Police appeal for information after baby seal shot

<p>Authorities have offered up a reward of $20,000 USD ($29,000 AUD) in exchange for information after a baby seal was shot dead on a beach in Southern California. </p> <p>The fatally wounded male sea lion was discovered on August 7th between two lifeguard stations at Bolsa Chica State Beach in Orange County, according to the National Oceanic and Atmospheric Administration (NOAA).</p> <p>The animal was estimated to be just two years old and died the day after it was found, with an examination revealing the seal had a gunshot wound to the back, according to a statement from NOAA.</p> <p>The agency said its law enforcement division was offering the reward "for information leading to a civil penalty or criminal conviction" in connection with the shooting, as the federal Marine Mammal Protection Act prohibits harassing, hunting, capturing or killing sea lions and other marine mammals.</p> <p>Violators can face criminal penalties, fines, and the forfeiture of any vessel involved in the incident.</p> <p>NOAA spokesperson Michael Milstein told <em><a href="https://www.usatoday.com/story/news/nation/2024/10/10/sea-lion-shot-california-beach-noaa-reward-offered/75605210007/" target="_blank" rel="noopener">USA TODAY</a></em> that the agency hopes "the reward offer will help encourage someone who may have seen something or heard something unusual to let us know to help us identify a suspect in this case."</p> <p>"We do get sea lions regularly that have been shot but this animal was still alive when found, so the wound was fresh and it was on a public beach, which hopefully increases the odds that someone knows something about what happened," Milstein added.</p> <p><em>Image credits: NOAA</em></p>

“This is life-changing information”: Shopper discovers little-known Bunnings hack

<p>A shopper has revealed the details of a little-known Bunnings store policy that will ensure a blooming garden. </p> <p>Georgia Magill, a young woman from Perth, was shopping for plants in the hardware store when she was urged by the cashier to keep her receipt.</p> <p>The uni student was shocked why she should hold on to the receipt for a small house plant, as the worker went on to explain why. </p> <p>“She was like, ‘Oh because they come with a 12 month warranty’,” Georgia explained in a now-viral TikTok video.</p> <p>“And then she goes: ‘It doesn’t really matter how they die we’ll just replace them for you within a 12 month period.’”</p> <p>The hardware store created the ‘Perfect Plant Promise’ in February 2020 which states all plants, except for seedlings, can be returned within 12 months of purchase if they die. </p> <p>Bunnings won’t just replace the plant, it also offers money back, if you’d prefer to give up on your gardening dreams.</p> <p>"This is life-changing information,” she concluded in the video. </p> <p>While the policy has been around for several years, many Aussies hadn’t heard of it either, commenting in shock on the TikTok video, which has been viewed almost 1.5 million times. </p> <p>“What? I have literally had Bunnings plants die within weeks,” one wrote,</p> <p>“I did know this… but I also refuse to let Bunnings know how many plants I’ve murdered,” another stated. </p> <p>Another person declared, “It’s such a good idea. I can’t believe I didn’t know it!!”</p> <p>Among the comments were more tips for former and current Bunnings workers, offering some extra tips on how to utilise the policy. </p> <p>“Ex Bunnings worker here, keep the original pot so we know what plant it is, not everyone in store is a plant expert,” one remarked.</p> <p>“(From a Bunnings worker) either take a photo of your receipt or ask for it to be sent via SMS as they fade! For any warranty item,” another suggested. </p> <p>However, one worker urged Aussies not to take advantage of the offer, saying, “We will return your plant with a receipt and ‘proof’ but please don’t abuse this system. Plants die.”</p> <p><em>Image credits: Getty Images / TikTok</em></p>

Plea for information after house fire kills four children

<p dir="ltr">Police have issued an urgent call for information following a devastating house fire in Melbourne’s southwest on Sunday. Four children died in the blaze, while their parents and an eight-year-old brother managed to escape.</p> <p dir="ltr">Two boys, aged 10 and three, and two girls, aged six and one, perished in the fire that broke out at around 1 am on Sunday at a family home in Werribee. Firefighters managed to gain entry to the home by breaking in through the garage.</p> <p dir="ltr">Mr Milloy, who was one of the 40 firefighters on the scene that managed to get the fire under control within an hour, said of the blaze, "The fire itself we've seen many times before, but the complexity involved, then having four children trapped inside the house and in a way feeling a bit helpless you can't get in there.” One firefighter was taken to hospital with chest pains.</p> <p dir="ltr">Victoria Police Detective Senior Sergeant Ashley Ryan said, "our hearts go out to the family and to the community". Arson Squad detectives spent Sunday combing through the scene, and they are still trying to piece together what caused the fire and where it started. Senior Sergeant Ryan said it was too early to say whether or not the fire was suspicious.</p> <p dir="ltr">Police have asked anyone who may have witnessed the inferno to get in touch with information. "We are calling on anyone who may have information who was driving past at the time, any dashcam footage, anything that may be able to assist us with the investigation.”</p> <p dir="ltr">Tributes have been growing at the site since the tragic event, with friends and loved ones of the family gathering in the street, and well-wishers leaving flowers, teddy bears, and messages of support near what remains of the home. A family friend, visibly emotional with grief, told 9News, "The family that survive … it's devastating.</p> <p dir="ltr">“It's just too sad. Too sad."</p> <p dir="ltr">The parents and son who survived the fire remain in stable condition at the Alfred Hospital.</p> <p dir="ltr"><em>Image: 9 News</em></p>

Four artists explain how science informs and inspires their work

<p>“The greatest scientists are artists as well,” said Albert Einstein. For as long as artistic expression has existed, it has benefited from interplay with scientific principles – be it experimentation with new materials or the discovery of techniques to render different perspectives. Likewise, art has long contributed to the work and communication of science.</p> <p>We asked four outstanding artists to comment on their work and its relationship to science. “Science is my muse,” replied Xavier Cortada, who marked the discovery of the ‘God particle’ with a set of triumphal banners. The same can be said for the other three: Suzanne Anker renders small worlds in petri dishes, Lia Halloran explores serendipity in science, and Daniel Zeller translates images from alien realms in his own artistic language.</p> <p>Credit: Raul Valverde</p> <p><strong>Suzanne Anker</strong></p> <p><img style="width: 496px; height: 496px;" src="https://oversixtydev.blob.core.windows.net/media/7843784/art-suzanne-anker-um.jpg" alt="" data-udi="umb://media/b5d9c04404f441f7a95f03be92b1a842" /></p> <p>Employed as a container for working with fungi, bacteria and even embryos, the glass dish named after bacteriologist Jules Petri is not only a fundamental of laboratory research: it has become a cultural icon.</p> <p>In my Remote Sensing series I use the Petri dish to juxtapose microscopic and macroscopic worlds. The title refers to new digital technologies that can picture places too toxic or inaccessible to visit.</p> <p>The fabrication of this piece began with 2D digital photographs, which were then converted into 3D virtual models. This petri dish with its luxuriant growth emerged from the 3D printer.</p> <p>These micro-landscapes offer the viewer a top-down topographic effect assembled by zeros and ones. Each configuration of these works takes the geometry of a circle, inspired by the Petri dish, and crosses the divide between the disciplines of art and science.</p> <p>The ‘bio art’ of Suzanne Anker explores the intersection of art and the biological sciences. Based in New York, Anker works in a variety of traditional and experimental mediums ranging from digital sculpture and installation to large-scale photography and plants grown under LED lights. Her work has been exhibited at the J. Paul Getty Museum in Los Angeles, the Pera Museum in Istanbul, and the International Biennial of Contemporary Art of Cartagena de Indias, Colombia. Anker is co-author of The Molecular Gaze: Art in the Genetic Age (2004) and co-editor of Visual Culture and Bioscience (2008). </p> <p><a href="http://www.suzanneanker.com">www.suzanneanker.com</a></p> <p>Credit: Lia Halloran</p> <p><strong>Lia Halloran</strong></p> <p><img style="width: 500px; height: 500px;" src="https://oversixtydev.blob.core.windows.net/media/7843785/art-lia-halloran-um.jpg" alt="" data-udi="umb://media/b408465517604d788b927db09d523746" /></p> <p>The 18th-century French astronomer Charles Messier set his telescopic sights on the grand prize of finding a lonely, wandering comet. He ended up amassing an astronomical inventory filled with galaxies, clusters and nebulae. A catalogue of 110 objects is credited to his journals and drawings.</p> <p>Deep Sky Companion is a series of 110 pairs of paintings and photographs of night sky objects drawn from the Messier catalogue.</p> <p>These works are about discovery and all the things we find when we are not seeking them. It relates to my own challenging first stabs at observing the night sky. In college I was given a small Celestron telescope for Christmas. Observing the Orion Nebula and nearby galaxies seemed to create a fold in time between Messier and myself.</p> <p>I would imagine his sessions observing through his telescope and the drawings he made to classify the natural world and make sense of the unknown above him.</p> <p>Each painting in the Deep Sky Companion series was created in ink on semi-transparent paper, which was then used as a negative to create the positive photographic equivalent using standard black-and-white darkroom printing. This process connects to the historical drawings by Messier, here redrawn and then turned back into positives through a photographic process mimicking early glass-plate astrophotography.</p> <p>Lia Halloran is an artist and academic based in Los Angeles. At Chapman University, in California’s Orange County, she teaches painting as well as courses that explore the intersection of art and science. Her art often makes use of scientific concepts and explores how perception, time and scale inform the human desire to understand the world, and our emotional and psychological place within it. She has held solo exhibitions in New York, Miami, Boston, Los Angeles, London, Vienna and Florence. Her work is held in public collections that include the Guggenheim in New York. </p> <p><a href="http://www.liahalloran.com">www.liahalloran.com</a></p> <p>Credit: Courtesy NASA Art Program</p> <p><strong>Daniel Zeller</strong></p> <p><img style="width: 440px; height: 440px;" src="https://oversixtydev.blob.core.windows.net/media/7843786/art-daniel-zeller-um.jpg" alt="" data-udi="umb://media/0f926a1a4fbf4b3ba0ca9804420ba3a8" /></p> <p>I was very grateful to have the Cassini mission as a launching point for this drawing. (Cassini’s 20-year mission ended in September 2017 when it crashed into Saturn.) There are obvious reasons Titan is so appealing: Saturn’s largest moon has an atmosphere, deserts and seas – it is an alien world with some characteristics we can relate to.</p> <p>The probe generated so much fascinating source material it was difficult to choose any single viewpoint, but there was something particularly intriguing about the image of Titan I finally settled on. Greyscale imagery naturally lends itself to broad interpretation, and the radar-mapping method suited my curiosity and my process; it seems to relay its subject as somehow simultaneously familiar and completely alien. Titan’s surface became a scaffold on which I could build and explore. The relative ambiguity of the source image allowed me wide latitude to interpret the moon as a stand-in for any not-yet-discovered world or landscape, while still allowing it to be grounded in the recognisable projection of topography.</p> <p>The Cassini mission was a truly amazing foray into the unknown. We are greatly enriched by the knowledge it collected. My work is but a humble homage to our immediate neighbourhood – once so far away and now a little bit closer – and to what is yet to be discovered on many frontiers.</p> <p>Daniel Zeller is an illustrator and painter based in New York.

My art wound up honouring the Nobel Prize-winning discovery of the Higgs boson, the particle that imbues all the others with mass. Five banners depict the five experiments used to make the discovery.</p> <p>Identifying the Higgs required the most complex machine humans have ever built, the Large Hadron Collider (LHC). The particle accelerator shoots protons at almost the speed of light along a 27 km tunnel. Every second 40 million protons collide with one another. These high-energy collisions make new particles and new mass.</p> <p>The LHC’s detectors did not directly measure the Higgs.</p> <p>They measured the paths taken by the photons, quarks and electrons created in the collisions. The curvature of the paths  revealed the charge and momentum of the particles, and the size of the signal their energy. The data told scientists there was another particle – the Higgs boson – produced in the collisions.</p> <p>Let me tell you why these experiments were so important. When physicists first came up with the Standard Model of physics, a theory to describe the forces and particles of nature, they couldn’t figure out how to give those particles mass.</p> <p>This was quite a problem, because particles with no mass would move at the speed of light and be unable to slow down enough to form atoms. Without atoms the universe would be very different.</p> <p>In the 1960s British physicist Peter Higgs and others independently came up with a theory to solve that problem. Just as marine creatures move in water, all particles in the universe move in a fundamental energy field – now commonly known as the Higgs field. As particles travel through the field, their intrinsic properties generate more or less mass – much as the properties of an animal create different degrees of drag as it moves through water.  Think of a barracuda and a manatee. The sleeker barracuda is going to move faster.</p> <p>Mathematically, the theory required the existence of a particle representing the ‘excited state’ of the field. This new particle – dubbed the Higgs boson – would be to the Higgs field what photons are to the electromagnetic field. Finding the particle involved scientists from 182 universities and institutes in 42 countries. On 4 July 2012, half a century after it was first postulated, CERN scientists announced its discovery.</p> <p>The detection itself was intricate and multilayered, and so were the artworks I created. Stained glass references the LHC as a modern-day cathedral that helps us understand the universe and shape our new world view. The oil painting technique honours those who came before us, the repetition of motifs across the five works celebrates internationalism, and rendering the work as ‘banners’ marks this as a monumental event.</p> <p>Most importantly, the background for the banners honours the scientific collaboration. It is composed of words from the pages of 383 joint publications and the names of more than 4,000 scientists, engineers and technicians. With this piece I wanted to create art from the very words, charts, graphs and ideas of this coalition of thinkers.</p> <p>It was a supremely important moment for humanity. I wanted the art to mark that event at the exact location where the experiment took place. These five banners hang at the exact location of the LHC, where the Higgs boson was discovered. That is where a scientific theory crystallised into a proven truth.</p> <p>It is my hope these banners will inspire future generations of physicists to continue to move humanity forward.</p> <p>Xavier Cortada is a painter based in Miami, Florida. His art regularly involves collaboration with scientists. As well as his art installation for CERN, he has worked with a population geneticist on a project exploring our ancestral journey out of Africa 60,000 years ago, with a molecular biologist to synthesise DNA from participants visiting his museum exhibit, and with botanists on eco-art projects. He estimates his installation at the South Pole using a moving ice sheet as an instrument to mark time will be completed in 150,000 years.</p> <p><a href="http://www.cortada.com">www.cortada.com</a></p> <p><strong>Related reading:</strong></p> <ul> <li><a href="https://cosmosmagazine.com/society/when-arts-and-science-collide/">When arts and science collide</a></li> <li><a href="https://cosmosmagazine.com/biology/how-eye-disorders-may-have-influenced-the-work-of-famous-painters/">Eye disorders influence famous painters</a></li> <li><a href="https://cosmosmagazine.com/technology/sciences-war-on-art-fraud/?hilite=%27artist%27">Science’s war on art fraud</a></li> </ul> <p><a href="https://cosmosmagazine.com/people/society/four-artists-influenced-by-science/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/cosmos-editors">Cosmos</a>. </p> <p> </p>

Surprising new coronavirus symptom has people itching for information

$350,000 reward for information on great-grandmother’s death

<p>A reward of $350,000 has been offered for information about the suspected hit-and-run death of a great-grandmother at a suburban intersection in Sydney’s south-west five years ago.</p> <p>On February 17, 2015, just after her 83rd birthday, Jean Harrison was found injured on the road at the corner of Shropshire Street and Dorset Place at Miller, near Liverpool.</p> <p>She was reportedly on her daily walk to the local shops when she was hit.</p> <p>Mrs Harrison suffered from cuts to her arm and the back of her neck but was unable to give police any information as she could not recall what had happened.</p> <p>She was taken to Liverpool Hospital in a serious condition and died the next morning.</p> <p>Soon after her death, a police strike force was established, which determined just how severe her injuries were after what they believe, was a hit and run case. However, other possibilities have not been ruled out.</p> <p>“Our investigators believe there are those in community who know more about how she came to be injured on the roadway but for some reason have not come forward,” said Liverpool City Police Area Command Crime Manager Detective Inspector Timothy Liddiard.</p> <p>“To them, I say, ‘Put yourself in the shoes of the family and imagine what it would be like to not know what happened to your loved one.’”</p> <p>Mrs Harrison had lived in the same house in Miller for close to 50 years after migrating to Australia from England. She was a grandmother and great-grandmother to at least 40 children.</p> <p>Her daughter Linda Edwards appealed to the public on Monday, saying there had been “seven more great-grandchildren and two great-great-grandchildren born who she will never get to hold”.</p> <p>“Mum was such a caring person who loved to help others and was truly happy when surrounded by her children, grandchildren and great-grandchildren,” said Ms Edwards.</p> <p>“We just want to find out what happened to Mum. Please if you know anything, contact police and let them know.”</p>

How the use of lasers and small satellites helps information get through space

<p>Satellites are becoming increasingly important in our lives, as they help us meet a demand for more data, exchanged at higher speeds. This is why we are exploring new ways of improving satellite communication.</p> <p>Satellite technology is used to navigate, forecast the weather, monitor Earth from space, receive TV signals from space, and connect to remote places through tools such as satellite phones and <a href="https://www.nbnco.com.au/learn/network-technology/sky-muster-explained">NBN’s Sky Muster satellites</a>.</p> <p>All these communications use radio waves. These are electromagnetic waves that propagate through space and, to a certain degree, through obstacles such as walls.</p> <p>Each communication system uses a frequency band allocated for it, and each band makes up part of the <a href="https://imagine.gsfc.nasa.gov/science/toolbox/emspectrum1.html">electromagnetic spectrum</a> – which is the name given to the range of all types of electromagnetic radiation.</p> <p>But the electromagnetic spectrum we are able to use with current technology is a finite resource, and is now completely occupied. This means old services have to make room for new ones, or higher frequency bands have to be used.</p> <p>While this poses technological challenges, one promising way forward is optical communication.</p> <p><strong>Communication with lasers</strong></p> <p>Instead of using radio waves to carry the information, we can use light from lasers as the carrier. While technically still part of the electromagnetic spectrum, optical frequencies are significantly higher, which means we can use them to transfer data at higher speeds.</p> <p>However, one disadvantage is that a laser cannot propagate through walls, and can even be blocked by clouds. While this is problematic on Earth, and for communication between satellites and Earth, it’s no problem for communication between satellites.</p> <p>On Earth, optical communication via fibre optic cables connects continents and provides enormous data exchanges. This is the technology that allows <a href="https://www.vox.com/2015/4/30/11562024/too-embarrassed-to-ask-what-is-the-cloud-and-how-does-it-work">the cloud</a> to exist, and online services to be provided.</p> <p>Optical communication between satellites doesn’t use fibre optic cables, but involves light propagating through space. This is called “free space optical communication”, and can be used to not only deliver data from satellites to the ground, but also to connect satellites in space.</p> <p>In other words, free space optical communication will provide the same massive connectivity in space we already have on Earth.</p> <p>Some systems such as the <a href="https://artes.esa.int/edrs-global">European Data Relay System</a> are already operational, and others like SpaceX’s <a href="https://www.space.com/see-spacex-starlink-satellites-in-night-sky.html">Starlink</a> continue to be developed.</p> <p>But there are still many challenges to overcome, and we’re limited by current technology. My colleagues and I are working on making optical, as well as radio-frequency, data links even faster and more secure.</p> <p><strong>CubeSats</strong></p> <p>So far, a lot of effort has gone into the research and development of radio-frequency technology. This is how we know data rates are at their highest physical limit and can’t be further increased.</p> <p>While a single radio-frequency link can provide data rates of 10Gbps with large antennas, an optical link can achieve rates 10 to 100 times higher, using antennas that are 10 to 100 times smaller.</p> <p>These small antennas are in fact optical lenses, and their compact size allows them to be integrated into small satellites called CubeSats.</p> <p>CubeSats are not larger than a shoebox or toaster, but can employ high speed data links to other satellites or the ground.</p> <p>They are currently used for a wide range of tasks including earth observation, communications and scientific experiments in space. And while they’re not able to provide all services from space, they play an important role in current and future satellite systems.</p> <p>Another advantage of optical communication is increased security. The light from a laser forms a narrow beam, which has to be pointed from a sender to a receiver. Since this beam is very narrow, the communication doesn’t interfere with other receivers and it’s very hard, if not impossible, to eavesdrop on the communication. This makes optical systems more secure than radio electromagnetic systems.</p> <p>Optical communication can also be used for <a href="https://qt.eu/understand/underlying-principles/quantum-key-distribution-qkd/">Quantum Key Distribution</a>. This technology allows the absolute secure exchange of encryption keys for safe communications.</p> <p><strong>What can we expect from this?</strong></p> <p>While it’s exciting to develop systems for space, and to launch satellites, the real benefit of satellite systems is felt on Earth.</p> <p>High speed communication provided by optical data links will improve connectivity for all of us. Notably, remote areas which currently have relatively slow connections will experience better access to remote health and remote learning.</p> <p>Better data links will also let us deliver images and videos from space with less delay and higher resolution. This will improve the way we manage our resources, including <a href="https://www.ga.gov.au/scientific-topics/community-safety/flood/wofs">water</a>, agriculture and forestry.</p> <p>They will also <a href="https://www.ga.gov.au/scientific-topics/earth-obs/case-studies/mapping-bushfires">provide vital real-time information in disaster scenarios such as bushfires</a>. The potential applications of optical communication technology are vast.</p> <p><strong>Banding knowledge together</strong></p> <p>Working in optical satellite communication is challenging, as it combines many different fields and research areas including telecommunication, photonics and manufacturing.</p> <p>Currently, our technology is far from achieving what is theoretically possible, and there’s great room for improvement. This is why there’s a strong focus on collaboration.</p> <p>In Australia, there are two major programs facilitating this - the Australian Space Agency run by the federal government, and the <a href="https://smartsatcrc.com/">SmartSat Cooperative Research Centre</a> (CRC), also supported by the federal government.</p> <p>Through the SmartSat CRC program, my colleagues and I will spend the next seven years tackling a range of applied research problems in this area.<!-- Below is The Conversation's page counter tag.

“Poorly informed teenager”: Vladimir Putin weighs in on Greta Thunberg

<p>Russian President Vladimir Putin has taken aim at Swedish schoolgirl and climate change activist Greta Thunberg, calling her a “poorly informed teenager” who is being “used by adults”. </p> <p>The world leader, 66, said the 16-year-old should quit “telling developing countries why they should live in poverty” over her campaign to cut fossil fuel use.</p> <p>While at the energy forum today Putin expressed he did not share the same excitement about Thunberg’s United Nations speech last month. </p> <p>The swede unleashed at the UN summit in New York when she denounced world leaders for failing to tackle climate change issues. </p> <p>While Putin did not name any specific groups, he said it was “deplorable” Thunberg was being used by groups to achieve their own goals. </p> <p>“I may disappoint you,” the Russian leader said at  a session titled<span> </span>Energy Partnership for Sustainable Growth<span> </span>in Moscow, Russia. </p> <p> “But I don't share the common excitement about the speech by Greta Thunberg.</p> <p>“No one has explained to Greta that the modern world is complex and different and...people in Africa or in many Asian countries want to live at the same wealth level as in Sweden.</p> <p>“Go and explain to developing countries why they should continue living in poverty and not be like Sweden.”</p> <p>US President Donald Trump mocked Thunberg and Canadian Member of Parliament Maxime Bernier labelled her alarmist and mentally unstable. </p> <p>Thunberg was not deterred by the comments however and said the mockery of children who were protesting showed her message had become “too loud to handle”. </p> <p>Putin said while young people who paid attention to environmental issues should be supported, he believes: “when someone is using children and teenagers in personal interests, it only deserves to be condemned.</p> <p>“I'm sure that Greta is a kind and very sincere girl. But adults must do everything not to bring teenagers and children into some extreme situations.”</p> <p>Thunberg made international headlines in September as she inspired millions of people across 150 countries to take to the streets for the Global Strike 4 Climate.</p>

URGENT: Major security breach after customers banking information hacked

<p>An urgent warning has been issued after hackers broke into a new payment system that put tens of thousands of customers’ personal banking information at risk.</p> <p>The scammers were able to obtain phone numbers, customer names, BSB and account numbers which were all linked to PayID. The fraudsters targeted unsuspecting customers with fake texts and phone calls in order to access the New Payments Platform (NPP) database and steal millions of dollars, according to the<span> </span><a rel="noopener" href="https://www.heraldsun.com.au/" target="_blank"><em>Herald Sun</em></a>.</p> <p>All big four banks around the country were affected as those impacted include Commonwealth Bank, National Australia Bank, ANZ and Westpac.</p> <p>Westpac emailed its customers urging them to remain vigilant, as the stolen data could be used to commit fraud.</p> <p>It is understood that the breach initially took place at another bank, but soon spread to other financial institutions.</p> <p>“We have heightened monitoring on your account and ask that you are on the lookout for any suspicious activity,” read the email.</p> <p>“We ask that you also be vigilant with any messages received via text or phone calls from an unidentified source.</p> <p>“We are urging all customers to be wary of any SMS phishing attempts – for example, a personalised message which looks like a legitimate message from Westpac or another bank, in an attempt to acquire banking credentials and password,” it said.</p> <p>The NPP was a highly anticipated initiative that was introduced in 2018, promising to deliver 24/7 instant transfers, as it moved cash in seconds.</p>

My Health Record: Why deleting your personal information is harder than it sounds

<p><strong><em>Robert Merkel is a lecturer in Software Engineering at Monash University. </em></strong></p> <p>Since the period for opting out of My Health Record began on July 16, experts in health, privacy and IT have raised concerns about the security and privacy protections of the system, and the legislation governing its operation.</p> <p>Now federal health minister Greg Hunt has <span style="text-decoration: underline;"><strong><a href="http://www.health.gov.au/internet/ministers/publishing.nsf/Content/health-mediarel-yr2018-hunt100.htm">announced</a></strong></span> two key changes to the system.</p> <p>First, the legislation will be amended to explicitly require a court order for any documents to be released to a law enforcement agency. Second, the system will be modified to allow the permanent deletion of records:</p> <p><em>In addition, the Government will also amend Labor’s 2012 legislation to ensure if someone wishes to cancel their record they will be able to do so permanently, with their record deleted from the system.</em></p> <p>But while this sounds like a simple change, permanently and completely deleting information from IT systems is anything but straightforward.</p> <p><strong>Systems designed for retention, not deletion</strong></p> <p>The My Health Record database is designed for the long-term retention of important information. Most IT systems designed for this purpose are underpinned by the assumption that the risk of losing information – through a hardware fault, programming mistake, or operator error – should be extremely low.</p> <p>The exact details of how My Health Record data is protected from data loss are not public. But there are several common measures that systems like it incorporate to greatly reduce the risks.</p> <p>At a most basic level, “deletion” of a record stored in a database is often implemented simply by marking a record as deleted. That’s akin to deleting something on paper by drawing a thin line through it.</p> <p>The software can be programmed to ignore any such deleted records, but the underlying record is still present in the database – and can be retrieved by an administrator with unfettered permissions to access the database directly.</p> <p>This approach means that if an operator error or software bug results in an incorrect deletion, repairing the damage is straightforward.</p> <p>Furthermore, even if data is actually deleted from the active database, it can still be present in backup “snapshots” that contain the complete database contents at some particular moment in time.</p> <p>Some of these backups will be retained – untouched and unaltered – for extended periods, and will only be accessible to a small group of IT administrators.</p> <p><strong>Zombie records</strong></p> <p>Permanent and absolute deletion of a record in such a system will therefore be a challenge.</p> <p>If a user requests deletion, removing their record from the active database will be relatively straightforward (although even this has some complications), but removing them from the backups is not.</p> <p>If the backups are left unaltered, we might wonder in what circumstances the information in those backups would be made accessible.</p> <p>If, by contrast, the archival backups are actively and irrevocably modified to permit deletion, those archival backups are at high risk of other modifications that remove or modify wanted data. This would defeat the purpose of having trusted archival backups.</p> <p><strong>Backups and the GDPR's 'right to be forgotten'</strong></p> <p>The problem of deleting personal information and archival backups has been raised in the context of the European Union’s General Data Protection Regulation (<span style="text-decoration: underline;"><strong><a href="https://ec.europa.eu/commission/priorities/justice-and-fundamental-rights/data-protection/2018-reform-eu-data-protection-rules_en">GDPR</a></strong></span>). This new EU-wide law greatly strengthens privacy protections surrounding use of personal information in member states.</p> <p>The “right to erasure” or “right to be forgotten” – <span style="text-decoration: underline;"><strong><a href="https://gdpr-info.eu/art-17-gdpr/">Article 17</a></strong></span> of the GDPR – states that organisations storing the personal information of EU citizens “shall have the obligation to erase personal data without undue delay” in certain circumstances.</p> <p>How this obligation will be met in the context of standard data backup practices is an interesting question, to say the least. While the legal aspects of this question are beyond my expertise, from a technical perspective, there is no easy general-purpose solution for the prompt deletion of individual records from archived data.</p> <p>In an <a href="https://www.acronis.com/en-us/blog/posts/backups-and-gdpr-right-be-forgotten-recommendations"><span style="text-decoration: underline;"><strong>essay</strong></span></a> posted to their corporate website, data backup company Acronis proposes that companies should be transparent about what will happen to the backups of customers who request that records be deleted:</p> <p><em>[while] primary instances of their data in production systems will be erased with all due speed … their personal data may reside in backup archives that must be retained for a longer period of time – either because it is impractical to isolate individual personal data within the archive, or because the controller is required to retain data longer for contractual, legal or compliance reasons.</em></p> <p><strong>Who might access those backups?</strong></p> <p>Data stored on archival backups, competently administered, will not be available to health professionals. Nor will they be available to run-of-the-mill hackers who might steal a practitioner’s credentials to gain illicit access to My Health Record.</p> <p>But it’s not at all clear whether law enforcement bodies, or anyone else, could potentially access a deleted record if they are granted access to archival backups by the system operator.</p> <p>Under amended legislation, such access would undoubtedly require a court order. Nevertheless, were it to be permitted, access to a deleted record under these circumstances would be contrary to the general expectation that when a record is deleted, it is promptly, completely and irrevocably deleted, with no prospect of retrieval.</p> <p><strong>Time required to work through the details </strong></p> <p>In my view, more information on the deletion process, and any legislative provisions surrounding deleted records, needs to be made public. This will allow individuals to make an informed choice on whether they are comfortable with the amended security and privacy provisions.</p> <p>Getting this right will take time and extensive expert and public consultation. It is very difficult to imagine how this could take place within the opt-out period, even taking into account the <a href="https://www.news.com.au/national/breaking-news/ehealth-records-opt-out-period-extended/news-story/d245f3601ee494959b854eb9b8c8ae15"><span style="text-decoration: underline;"><strong>one-month extension</strong></span></a> just announced by the minister.</p> <p>Given that, it would be prudent to pause the roll-out of My Health Record for a considerably longer period. This would permit the government to properly address the issues of record deletion, as well as the numerous other privacy and security concerns raised about the system.</p> <p><em>Written by Robert Merkel.

Why respite care is so important for informal carers

<p><em><strong>Marissa Sandler is the CEO and co-founder of <span style="text-decoration: underline;"><a href="http://www.careseekers.com.au/" target="_blank">Careseekers</a></span>. Previously a social justice lawyer and researcher for over 15 years, Marissa is passionate about helping people live with dignity and finding innovative solutions to problems.</strong></em></p> <p>The end of the year is a great time of year, no school traffic, quiet streets and most of Australia takes a break. However, if you are an informal carer this may not be the case. Caring is a full-time job and doesn’t stop because its summer or Christmas or New Years. It is however very important that as a carer you do take a break. The best way to do this is by engaging respite care services of some description.</p> <p>Here are some fast facts to read about respite care so that you can take a break over the festive season.</p> <p><strong>What is respite care?</strong></p> <p>Respite care is care that is taken over by someone else to relieve an informal carer of their care giving duties for a loved one.</p> <p><strong>How does it work?</strong></p> <p>Respite care can be delivered in many forms.</p> <p><strong>1. Respite care in the home</strong> – A care or support worker can come into your home and take the load off you by looking after a loved one for a few short hours or even a few days/weeks. Connecting directly to care and support workers on platforms like <span style="text-decoration: underline;"><strong><a href="http://www.careseekers.com.au/" target="_blank">Careseekers</a></strong></span> is one way to find people who deliver respite care services.</p> <p><strong>2. Respite care in the community</strong> – Most local communities have adult day centres or neighbourhood centres where a loved one can go for the day. They will do casual drop ins as well on days when you may be feeling extra frazzled.</p> <p><strong>3. Residential based respite care</strong> – This type of centre enables loved ones to stay for an extended period of time – a few weeks and can be helpful if you need to travel.</p> <p><strong>4. Family or friend care respite</strong> – Close family and friends may be available to help you, especially if you open up and explain your situation and how additional help would lighten your load. There are also organisations who can send a volunteer to do some respite care.</p> <p>Emergency respite care and information on other types of respite care is available through <span style="text-decoration: underline;"><strong><a href="https://www.myagedcare.gov.au/caring-someone/respite-care" target="_blank">My Aged Care</a></strong></span> or  <span style="text-decoration: underline;"><strong><a href="https://www.carergateway.gov.au/what-is-respite-care?gclid=EAIaIQobChMIn5rRgJTo1wIVRyQrCh3uXQGuEAAYAiAAEgIomfD_BwE" target="_blank">The Carer Gateway</a></strong></span>.</p> <p><strong>Real life story</strong></p> <p>It was difficult for Cathy to watch her vivacious, opinionated mother Mary spiral into the depths of dementia. As her mother deteriorated further, Dora and her siblings assessed their options. They were adamant about keeping Mary at home. Luckily Cathy was able to move in with her mother and take on a full time caring role.</p> <p>Caring can be exhausting and Cathy soon found she needed some time out. With her other siblings unable to help, the family decided to hire in-home care workers. During her time off Cathy would book into a hotel and just have some down time. It made all the difference to the type of carer she was to her mum during the week. “It really recharged me for the week ahead. I was more patient and as a result mum was happier. If you are a full-time carer for a loved one you just have to have some time out.”</p>

Tennis Australia embracing the information age

<p>Tennis Australia had other goals in mind, besides keeping the weather out, when they had the roof built at Margaret Court Arena. Those goals included taking the arena and tennis championships into the information age. The first step? Wi-Fi antennas built into the gantries that surround the sliding ceiling that beam web access to every ticket holder.&nbsp;</p><p>“The other day I got 48 megabits,” boasts Tennis Australia chief information officer Samir Mahir said.</p><p>Mahir and his team of 200 people (during the tournament, it's usually 24) manage a computer stack of hundreds of terabytes of data, and they must make the collection and dispersal of that data seamless for the punters watching. So what exactly does this mean? Good question. They’re responsible for creating and distributing apps to offer a range of experiences, and watch social media for good or bad impressions.</p><p>They monitor crowd density and movement with sensors throughout the precinct, learning from the police in cities like New York and Chicago how to sense trouble before it begins. They capture video from every court and beam it to security, referees, and journalists with a presentation that is tailored to the audience.</p><p>Being able to monitor what is happening allows the tennis, and everything that goes within the precinct, to be a seamless experience for all – for example, when one of the several food stores around the precinct is running low on soda, Mahir can monitor the situation down to the type of soda that is needed via an iPad app built to centrally monitor inventory.&nbsp;</p><p>“Two years ago we had a supervisor for each group of [ball] kids,” Mahir revealed. “They took notes about each ball kid. At the end of the day, they talk to them, and after the matches are over, they put [the information] into spreadsheets.&nbsp;</p><p>“Now we have the iPad app, they can balance the skill set of each ball kid for each court. They capture on the iPad app straight away – by the time the game is over, they already have a report.”</p><p>Tennis Australia has bigger picture goals in mind here: to get more people on the court.&nbsp;“My goal is to see how we can convert some of those technologies and customise for the grassroots,” Mahir explained. “It's no longer about people coming into the website... or coming into a clinic, but providing tools and looking into technology that can give us data and service them properly.”</p><p>This includes making it easy and accessible for players to get the information that will help them. Manufacturers including Babolat and Wilson are now making racquets capable of capturing data on every swing –&nbsp;down to the exact speed and trajectory of spin on the ball at the moment of contact.</p><p>Mahir imagines capturing this data in a central warehouse, which could also monitor players' engagement, how often they are playing, to make sure they don't give up on the game. He wants one million players, one million fans and one grand slam champion in “the next couple of years”.</p>
