NYU Abu Dhabi researchers design simulator to help stop the spread of 'fake news'

Apr 27 2021 - 00:04
To improve news literacy and reduce the spread of misinformation, NYUAD Center for Cybersecurity researcher and lead author Nicholas Micallef is part of a team that designed Fakey, a game that emulates a social media news feed and prompts players to use available signals to recognize and scrutinize suspicious content and focus on credible information. Players can share, like, or fact-check individual articles.

Few young adult men have gotten the HPV vaccine, study finds

Apr 27 2021 - 00:04
Using data from the 2010-2018 National Health Interview Surveys, Michigan Medicine researchers found that just 16% of men who were 18 to 21 years old had received at least one dose of the HPV vaccine at any age. In comparison, 42% of women in the same age bracket had gotten at least one shot of the vaccine.

Exploiting non-line-of-sight paths for terahertz signals in wireless communications

Apr 27 2021 - 00:04
After developing a link discovery method in 2020 using terahertz radiation, Brown and Princeton researchers addressed what would happen if a wall or other reflector creates a non-line-of-sight path from the base station to the receiver. In APL Photonics, they consider two different generic types of transmitters and explore how their characteristics can be used to determine whether an NLOS path contributes to the signal received by the receiver.

New 2D superconductor forms at higher temperatures than ever before

Apr 27 2021 - 00:04
Researchers at the US Department of Energy's Argonne National Laboratory have discovered a new way to generate 2D superconductivity at an interface of an insulating oxide material, at a higher transition temperature than ever seen before for these materials.

Researchers find mechanism underlying muscle weakness in Becker disease

Apr 27 2021 - 00:04
Muscle weakness in patients with Becker disease is caused by unusual electrical activity in muscle fibres termed 'plateau potentials' that make them temporarily inactive, says a study published today in eLife.

Researchers show new holistic approach to genetics and plant breeding

Apr 27 2021 - 00:04
A group of researchers has discovered a new approach to cereal plant breeding that takes into account the internal "calculator" of plant seeds that makes them continuously reorganize themselves (global coherence). The approach includes unforeseen and unintended changes in the plant when genetically manipulated by the plant breeders. The researchers expect that the method can be used to improve the world's crops much more efficiently.

Salk scientists reveal how brain cells in Alzheimer's go awry, lose their identity

Apr 27 2021 - 00:04
Despite the prevalence of Alzheimer's, there are still no treatments, in part because it has been challenging to study how the disease develops. Now, scientists at the Salk Institute have uncovered new insights into what goes awry during Alzheimer's by growing neurons that resemble--more accurately than ever before--brain cells in older patients. And like patients themselves, the afflicted neurons appear to lose their cellular identity.

Polymer-based coatings on metallic implants improve bone-implant integration

Apr 27 2021 - 00:04
Although bone has some capacity to regenerate, large bone defects cannot be healed without major medical procedures. Metallic implants are widely used, but their bioinertness poses a challenge. In Biointerphases, researchers showcase approaches that are alternatives to metallic implants and use natural polymer coatings to improve bone-implant integration, also known as osseointegration. Establishing a strong chemical interaction between a metal and a completely organic and natural polymer is a significant advancement in bone tissue engineering.

Solar-powered desalination unit shows great promise

Apr 27 2021 - 00:04
Freshwater accounts for only about 2.5% of water on Earth, so much of the world experiences serious water shortages. In AIP Advances, scientists report the development of a highly efficient desalination device that uses a titanium-containing layer capable of absorbing solar energy. When sunlight strikes the layer, it heats rapidly and vaporizes the water. By placing the unit in a transparent container with a sloped quartz roof, the water vapor can be condensed and collected.

California campaign lowers statewide C-section rate, Stanford-led study finds

Apr 27 2021 - 00:04
A four-year effort has reduced the rate of cesarean sections for low-risk, first-time mothers in California, according to a study led by researchers at the Stanford University School of Medicine and the California Maternal Quality Care Collaborative.

Fair climate policy could help reduce extreme poverty

Apr 27 2021 - 00:04
Ambitious climate policies could help to reduce extreme poverty in developing countries. This is the result of a new study by scientists of the Potsdam Institute for Climate Impact Research (PIK) - a result that is in contrast to wide-spread assumptions that climate change mitigation comes with a trade-off for poverty reduction. To turn climate policies and poverty reduction into a win-win situation for planet and people, a progressive redistribution of emission pricing revenues and a fair international burden sharing are key.

Association of facial paralysis with mRNA COVID-19 vaccines

Apr 27 2021 - 00:04
What The Study Did: This analysis uses the World Health Organization pharmacovigilance database to explore the potential safety signal of facial paralysis after COVID-19 vaccination. When compared with other viral vaccines, mRNA COVID-19 vaccines did not display a signal of facial paralysis.

USPSTF reaffirms recommendation of screening for high blood pressure in adults

Apr 27 2021 - 00:04
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) reaffirms its earlier recommendation of screening for high blood pressure in adults 18 years or older with office blood pressure measurement and obtaining measurements outside of the clinical setting for confirming a diagnosis of high blood pressure before starting treatment.

Benefits of AstraZeneca COVID-19 vaccine outweigh its risks

Apr 27 2021 - 00:04
The AstraZeneca COVID-19 vaccine is suspected of being linked to a small number of deep vein thrombosis cases, which led several countries to suspend AstraZeneca injections. Researchers explored a hypothesis that this pause, even if short, could cause additional deaths from the faster spread of COVID-19. They report using an epidemiological model and statistical analysis to estimate excess deaths resulting from suspending AstraZeneca vaccinations and those potentially linked to DVT-adverse events in France and Italy.

Nontoxic, flexible energy converters could power wearable devices

Apr 27 2021 - 00:04
Wearable electronics have increasingly become a part of everyday life, so researchers wondered if these could be powered by harvesting electricity from waste heat. Further inspiration came from a desire to ultimately fabricate energy converting devices from the same materials as the active devices themselves. In Applied Physics Letters, the researchers report the design and fabrication of single-wall carbon nanotube thermoelectric devices on flexible polyimide substrates as a basis for wearable energy converters.

Physicists net neutron star gold from measurement of lead

Apr 27 2021 - 00:04
Nuclear physicists have made a new, highly accurate measurement of the thickness of the neutron "skin" that encompasses the lead nucleus in experiments conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility and just published in Physical Review Letters. The result, which revealed a neutron skin thickness of .28 millionths of a nanometer, has important implications for the structure and size of neutron stars.
