Privacy Risks of Home Security Cameras
Researchers have used data from a major home Internet Protocol (IP) security camera provider to evaluate potential privacy risks for users. The researchers found that the traffic generated by the cameras could be monitored by attackers and used to predict when a house is occupied or not.

Improving Ethical Models for Autonomous Vehicles
There’s a fairly large flaw in the way that programmers are currently addressing ethical concerns related to artificial intelligence (AI) and autonomous vehicles (AVs). Namely, existing approaches don’t account for the fact that people might try to use the AVs to do something bad.

Future Texas Hurricanes: Fast Like Ike or Slow Like Harvey?
Climate change will intensify winds that steer hurricanes north over Texas, increasing the odds for fast-moving storms like 2008’s Ike compared with slow-movers like 2017’s Harvey, according to new research.

Increases in Greenhouse Gas, Particulate Pollution Emissions Drive Drying around the Globe
Researchers have identified two signatures or “fingerprints” that explain why arid conditions are spreading worldwide, and why the Western United States has tended toward drought conditions since the 1980s while the African Sahel has recovered from its prolonged drought.

Heatwave Trends Accelerate Worldwide
The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950s. New research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons. As expected, that number is also on the rise.

Reverse Engineering of 3D-Printed Parts by Machine Learning Reveals Security Vulnerabilities
Over the past thirty years, the use of glass- and carbon- fiber reinforced composites in aerospace and other high-performance applications has soared along with the broad industrial adoption of composite materials. Machine learning can make reverse engineering of complex composite material parts easy.

Chances of 40°C Days in the U.K. Increasing
The highest temperature ever recorded in the U.K. is 38.7°C (101.6 F) set in Cambridge in July 2019. This prompts the question of whether exceeding 40°C is now within the possibilities of the U.K. climate. A new study by the Met Office says that on current global warming trends, Britain could see 40°C (104 F) days every 3-4 years on average within a few decades.

Coronavirus and Cancer Hijack the Same Parts in Human Cells to Spread – and Our Team Identified Existing Cancer Drugs that Could Fight COVID-19
Most antivirals in use today target parts of an invading virus itself. Unfortunately, SARS-CoV-2 – the virus that causes COVID-19 – has proven hard to kill. But viruses rely on cellular mechanisms in human cells to help them spread, so it should be possible to change an aspect of a person’s body to prevent that and slow down the virus enough to allow the immune system to fight the invader off. Nevan Krogan writes in The Conversation, “I am a quantitative biologist, and my lab built a map of how the coronavirus uses human cells. We used that map to find already existing drugs that could be repurposed to fight COVID-19 and have been working with an international group of researchers called the QBI Coronavirus Research Group to see if the drugs we identified showed any promise. Many have.

The Danger of Drug Research in a Hurry
The number of studies on COVID-19 is increasing just as rapidly as the number of infections at the beginning of the pandemic. Felicitas Witte writes in the Frankfurter Allgemeine Zeitung [in German] that in mid-March there were still 84, today there are more than 2,200. Wolf-Dieter Ludwig, chairman of the drug commission of the German medical profession and an oncologist in Berlin, is concerned about the number. “This is more mass than class,” he says. “Many of the ongoing studies are so badly planned that it is already clear that a reliable result will not come out.” The corona crisis culminated in what he had been criticizing for a number of years: Medicines should come onto the market faster and faster, but the quality of the studies and ultimately the patient suffered as a result.

A Coronavirus Vaccine Is Still Months Away, but an Antibody Treatment Could Be Closer
Vaccines have gotten all the attention in the race to fight Covid-19, but there is a major push in the United States to develop antibody therapies to treat coronavirus. Jen Christensen writes for CNN that there’s so much of a push that some scientists think these treatments may be available this year, even before a vaccine.

UA Little Rock to Offer New Bachelor’s Degree in Cybersecurity
The University of Arkansas at Little Rock is introducing a new four-year degree program in cybersecurity in the fall 2021 semester to help meet the rising demand for cybersecurity professionals. The university says the new degree program will attract more government and industry jobs to the region, while helping to fill a growing need for more trained cybersecurity professionals.

Controversy on COVID-19 Mask Study Spotlights Messiness of Science during a Pandemic
Late last week, a group of researchers posted a letter that they had sent to the Proceedings of National Academy of Sciences (PNAS) requesting the retraction of a study published the week before that purportedly showed mask use was the most effective intervention in slowing the spread of COVID-19 in New York City. Stephanie Soucheray writes for CIDRAP that though PNAS editors have yet to respond to the request, scientists have roundly criticized the study’s methodology, and the entire kerfuffle has highlighted the difficulty of “doing science” amid a full-blown pandemic.

The World's Biggest Waves: How Climate Change Could Trigger Large Landslides and “Mega-Tsunamis”
Natural hazards which are triggered, made more frequent, or exacerbated by climate change can’t be prevented, but damage to infrastructure and populations can be minimized. This can be achieved through scientific understanding of the physical processes, site-specific engineering risk analysis and coastal management of hazard-prone regions.
Ultrasensitive Measurements Detect Nuclear Explosions
Imagine being able to detect the faintest of radionuclide signals from hundreds of miles away. Scientists have developed a system which constantly collects and analyzes air samples for signals that would indicate a nuclear explosion, perhaps conducted secretly underground. The system can detect just a small number of atoms from nuclear activity anywhere on the planet. In terms of sensitivity, the capability – in place for decades – is analogous to the ability to detect coronavirus from a single cough anywhere on Earth.
Would You Fall for a Fake Video? Research Suggests You Might
Deepfakes are videos that have been manipulated in some way using algorithms. As concerns about election interference around the globe continue to rise, the phenomenon of deepfakes and their possible impact on democratic processes remains surprisingly understudied.
Security Solution Traps Cybercriminals in a Virtual Network
Researchers are developing a new cyber-security deception solution that uses artificial intelligence to lure hackers away and prevent breaches of network systems. The “Lupovis” solution under development by the team at the University of Strathclyde’s Center for Intelligent and Dynamic Communications makes the hunter become the hunted.
