Phys.org / Harmless viruses trap Salmonella on flexible polymer in portable microfluidic sensor
Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding ...
Phys.org / Thawing Arctic soil awakens only half of soil microbes, new study reveals
As the Arctic warms at an unprecedented rate, frozen soils that have remained locked in ice for most of the year are now thawing for longer periods. Yet new research led by an international team including scientists from ...
Dialog / Scientists uncover hidden parasite diversity in barb fish from the Sea of Galilee
When most people think about biodiversity in lakes and rivers, they imagine fish, plants, or perhaps birds and amphibians. But beneath the surface exists another world that often goes unnoticed: microscopic parasites that ...
Phys.org / Climate-driven extreme fire danger cannot be prevented by carbon neutrality alone, study warns
A new study warns that unless atmospheric carbon is reduced immediately, future summers will become even hotter and future wildfires even more destructive. A research team led by Professor Seung-Ki Min of the Department of ...
Phys.org / Gaming monkeys' curiosity: Japanese macaques actively explore moderately uncertain stimuli
The intrinsic information-seeking impulse we call curiosity is independent of extrinsic rewards, such as food or mating opportunities. Curiosity is purely the pursuit of understanding the unknown, driving both humans and ...

Phys.org / How cells 'back up' DNA replication to survive severe damage
Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks (ICLs), which chemically ...
Phys.org / Why plant extinctions may rise by 2100 even if species keep shifting ranges
No matter how fast a species under threat can move, escape can only be successful if the new destination can meet its needs. An ecological modeling study from the University of California, Davis, found that 7% to 16% of global ...
