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 ...
Phys.org / These monster black holes did not form the usual way—their history of violence is written into spacetime ripples
The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up through a series of ...
Phys.org / Novel nanoparticle therapy using manganese could improve cancer treatment
A research team led by the University of Michigan College of Pharmacy and the University of Texas MD Anderson Cancer Center has developed a new type of nanoparticle therapy that could make cancer immunotherapy safer and more ...
Phys.org / Every dollar spent on forest fuel treatments saves $3.75 in wildfire damages, study finds
Every dollar spent on forest fuel treatments saves about $3.75 in wildfire damages, according to a new study, led by researchers at the University of California, Davis, of nearly 300 fires in the western United States. The ...

Scientists from the Natural History Museum, London have described a new genus and species of parasitic wasp found within the Museum's collections, and named it as a birthday present for Sir David Attenborough.
Phys.org / Trafficked pangolin DNA reveals hotspots of illegal wildlife trade
Small samples of DNA can reveal hotspots and trade routes in the illegal wildlife trade, according to a study published in the open-access journal PLOS Biology by Sean Heighton and Philippe Gaubert of the University of Toulouse ...
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 ...
Phys.org / Archaeologists unearth evidence of dogs being traded within Mayan societies
A University of Calgary archaeologist has found evidence that the Classic Period Maya were trading live dogs over long distances between the northern Yucatan peninsula and central Chiapas regions.
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 / Sexual arousal can lead to tunnel vision, blinding people to rejection cues
Sexual arousal can lead to "tunnel vision" that makes it more difficult to recognize when someone is just not that into you, according to new research in Personality and Social Psychology Bulletin.
Phys.org / How evolution sculpts the facial shapes of birds and mammals
Shapes of beaks and snouts come in an extraordinary range of forms, reflecting adaptations to different lifestyles and environments. Yet beneath this diversity lies a paradox: across birds and mammals, faces are built using ...
Phys.org / Deforestation lessens Amazon rainfall—and climate change hastens that process, study finds
Climate change makes the southern Amazon's rain increasingly sensitive to deforestation, a new study finds. Clearing large areas of forest can trigger severe and lasting reductions in rainfall regardless of climate, but as ...
