Phys.org / Researchers reveal key role of interstellar polycyclic aromatic hydrocarbons in molecular clouds
Polycyclic aromatic hydrocarbons (PAHs) are important carriers of organic matter throughout the universe. As organic molecules, they play a central role in interstellar chemistry and are closely related to the origin of prebiotic ...
Phys.org / Interpretable machine learning to accelerate nanocatalyst discovery
A fast and accurate surrogate model screens over 10,000 possible metal-oxide supports for a platinum nanocatalyst to prevent sintering under high temperatures.
Dialog / Voodoo economics: How wildlife trade for ritual use is wiping out Africa's vultures
For some people, the mention of voodoo evokes something like a scene from the James Bond novel "Live and Let Die," featuring occult ceremonies with snakes and animal sacrifice. Animal sacrifice was widespread among human ...
Phys.org / How personalized algorithms lead to a distorted view of reality
The same personalized algorithms that deliver online content based on your previous choices on social media sites like YouTube also impair learning, a new study suggests.
Phys.org / Is the 'hot hand' real? 'Jeopardy!' offers clues
Stanford researchers found that contestants bet bigger on Daily Doubles when they're on a streak—even though their performance barely budges.
Phys.org / Unique aquatic plant has three concurrent CO₂-concentrating mechanisms
A new study led by the Wuhan Botanical Garden of the Chinese Academy of Sciences (WBG, CAS) has identified a unique trait in the aquatic plant Ottelia alismoides—it can simultaneously employ three distinct CO₂-concentrating ...
Phys.org / Urban fringe areas show great potential for forest restoration
A study conducted at the University of São Paulo (USP) by researchers from the Nucleus of Analysis and Synthesis of Nature-Based Solutions (BIOTA Synthesis), a FAPESP Science Center for Development (SCD), identified approximately ...
Medical Xpress / Five things to know about staying cool in the heat
Australia is no stranger to hot weather, and Griffith University researchers have compiled five handy things to be aware of so we do not place our health at risk during the summer months.
Phys.org / Golden retriever and human behaviors are driven by same genes, researchers discover
A study led by researchers at the University of Cambridge provides a window into canine emotions, revealing why some golden retrievers are more fearful, energetic or aggressive than others.
Tech Xplore / Low-cost green hydrogen: New electrode design dramatically reduces wear in membrane electrolyzers
A University of California, Berkeley chemist has engineered a new technology that could make hydrogen-producing fuel cells last longer and hasten the arrival of cost-competitive, eco-friendly versions of the fuel source.
Phys.org / When darkness shines: How dark stars could illuminate the early universe
Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be examples of dark stars. The concept of dark stars has existed for some time and could alter ...
Phys.org / Biobased concrete substitute can give coastal restoration a natural boost
An innovative alternative to concrete could enable important coastal restoration work to take place. The material Xiriton, made with local grass species and seawater, captures CO2 instead of emitting it, as conventional concrete ...
