Tech Xplore / AI could make it easier to create bioweapons that bypass current security protocols
Artificial intelligence is transforming biology and medicine by accelerating the discovery of new drugs and proteins and making it easier to design and manipulate DNA, the building blocks of life. But as with most new technologies, ...
Phys.org / Trauma in a puppy's first six months linked to adult aggression, says new study
As many dog owners can attest, their four-legged companions are delightful and loving. But for others, their animals have an aggressive side, such as biting and attacking strangers, which may ultimately lead to them having ...
Phys.org / Ancient viral DNA is essential for human embryo development, study shows
Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ERVs) that infected our ...
Phys.org / Early humans dined on giant sloths and other Ice Age giants, archaeologists find
What did early humans like to eat? The answer, according to a team of archaeologists in Argentina, is extinct megafauna, such as giant sloths and giant armadillos. In a study published in the journal Science Advances, researchers ...
Phys.org / Microplastics reduce soil fertility and boost production of a potent greenhouse gas, study shows
More than 90% of plastic waste ends up in the soil, where it breaks down into microplastics that are invisible to the naked eye. Microplastic pollution of the soil poses a severe threat to soil health as it can harm essential ...
Phys.org / First comprehensive review of plastic pollution in the Amazon reveals contamination poses urgent health risks
Plastic may well be a useful everyday item, but its careless disposal in oceans and inland waterways is a pressing global problem. Plastic pollution poses a significant threat to human health and the health of our planet. ...
