Phys.org / Talking to your children about consent and sexual violence can be hard. Here's how to start the conversation
There have been multiple high-profile alleged incidents of sexual violence against women and girls in news headlines this month. Some involve teenage boys.
Phys.org / Low oxygen could limit insects' uphill escape from climate warming
Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...
Tech Xplore / Aurivillius-type materials could lower the operating temperature of fuel cells
Fuel cells, devices that generate electricity by converting the chemical energy of hydrogen or other fuels via electrochemical reactions, are promising solutions for powering large electric vehicles, industrial sites and ...
Phys.org / Candida fungi can burst immune cells and shape-shift to evade immunity
Candida auris and Candida albicans are microscopic fungi that cause life-threatening human infections, killing almost a million people globally every year. The World Health Organization lists both species among the top four ...
Medical Xpress / No benefit of heart CT scan in patients with acute chest pain, trial finds
Coronary CT angiography (CTCA) scans do not reduce the risk of heart attacks or cardiac death over three years in patients with acute chest pain whose heart attacks have been excluded, according to the results of a trial ...
Phys.org / Compound with the potential to treat drug-resistant HIV identified
A large international team has developed a new compound that showed strong antiviral activity against HIV, including some drug-resistant variants.
Phys.org / Discovery reveals rapid pathways to complex aromatic molecules in space
A team of researchers led by the University of Hawaiʻi at Mānoa Department of Chemistry has uncovered a faster way large carbon-based molecules may form in space, helping solve a long-standing mystery about how some of the ...
Tech Xplore / Vertical microrods boost electricity generation from evaporation by accelerating ion flow
Evaporation, the process by which water becomes vapor and disperses into the environment, draws heat from its surroundings. This heat, also known as atmospheric thermal energy, is abundant but diffuse, making it difficult ...
Phys.org / ASTRID traces 13.5 billion years of black hole and galaxy evolution
In dark skies at night, distant starlight twinkles and speaks to vast cosmic histories almost as old as time itself. New data from instruments such as NASA's James Webb Space Telescope are helping astrophysicists probe deep ...
Tech Xplore / Life cycle assessment identifies cleaner biodiesel pathways across five feedstocks
To mitigate climate change and limit global warming to within 1.5°C, scaling up global renewable energy capacity is an important goal. However, the transition to clean energy faces significant resource constraints.
Dialog / Beyond the gold standard: An ultrathin chromium layer makes durable perovskite solar cells more affordable
Gold has been the safe choice for perovskite solar cells. We found a way to stop needing it.
Phys.org / Mirror-image molecules steer electron spins and lift perovskite solar cell efficiency
Some molecules come in two "handed" forms. This property, called chirality, can influence not only how molecules interact with light but also which electron spins they allow to pass. Researchers at the University of Osaka ...
