Phys.org / New plastic film covered in thousands of tiny pillars can tear apart viruses on contact
Think of how many surfaces you touch every day, from your kitchen bench to the handrail on the bus or train, your work desk and your phone screen.
Phys.org / Milk's hidden carbon bill is bigger than advertised as damaged grass and soils drive emissions higher
Livestock farming causes a significant share of the world's greenhouse gas emissions. According to a new study, the carbon footprint of milk may be considerably larger than commonly calculated when carbon released from the ...
Phys.org / Magnet with near-zero external field could reshape future electronics
An international research team led by DTU has developed a new magnetic material that features a stable internal magnetic structure, almost no external magnetic field, and retains these properties above room temperature. These ...
Phys.org / Carbon nanotubes are closing the gap on copper conductivity
Carbon nanotubes are one technology that many observers believe hasn't quite lived up to the extreme hype that surrounded them when they first appeared on the scene in the late 1990s. At that time, much was made of their ...
Phys.org / This life‑threatening bacterium's hidden motor just gave medicine an unexpected opening to fight back
Scientists have mapped in unprecedented detail the structure of Vibrio bacteria, which can cause life-threatening infections linked to antibiotic resistance. The King's College London team behind the study, published in Nature ...
Phys.org / Inside 18 years of ape minds, a vast record that may upend how human intelligence began
A pioneering project led by researchers from the University of Stirling and the Max Planck Institute has opened the door for new insights into the evolutionary origins of human intelligence, by compiling the largest dataset ...
Phys.org / Saturday Citations: Cruise ship pathogen spread in ancient Rome; Plus: Pomegranates, retinal implants
This week, researchers reported that malaria influenced population distribution in Africa thousands of years ago. Mathematicians at MIT report that classical physics formulations can explain quantum phenomena. And a study ...
Phys.org / 'Aquila Booster' challenges theoretical limits of particle acceleration in pulsar wind nebulae
The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron ...
Phys.org / Scraped from ancient Roman toilets, these crusted remains expose a pathogen found far earlier than expected
Modern analytical tools are no less than a time machine. From their 21st-century labs, researchers can peer into the everyday lives, hygiene, and even the parasites that plagued the people who lived centuries ago. In one ...
Phys.org / New approach to detect ultra-rare part-per-sextillion isotopes could also sharpen dark matter searches
The detection and study of isotopes, atoms of the same element that have different numbers of neutrons, could expand the scope of physics research and enable new scientific discoveries. So far, rare isotopes have been primarily ...
Medical Xpress / Microplastics in human liver could be fueling global surge in disease
There is considerable evidence that microplastics and nanoplastics are present in the livers of humans, and wild animal populations on land and in the ocean. Now experts in environmental and human health are investigating ...
Medical Xpress / Mechanical forces from the beating heart may help prevent cancer cell growth
Scientists may have discovered another way the human body tries to protect itself from cancer. New research on mice suggests that the heart's constant beating may prevent tumor growth in cardiac tissue. Most organs are vulnerable ...
