Phys.org / Decoy molecules trick soil bacteria into attacking persistent pollutants without genetic engineering
In a study published in the Journal of Materials Chemistry A, Nagoya University researchers demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent ...
Phys.org / Wildlife trade increases pathogen transmission: What 40 years of data say about spillover
Hedgehogs, elephants, pangolins, bears or fennec foxes: many wild species are sold as pets, hunting trophies, for traditional medicine, biomedical research, or for their meat or fur. These practices, whether legal or illegal, ...
Phys.org / Mathematical signature spots when competition is fair, winner-take-all, or too soft
A University of Houston researcher and his collaborators have developed a mathematical model that helps identify whether a competitive environment is healthy, stagnant or skewed. Published in the journal npj Complexity, the ...
Phys.org / How surface chemistry impacts the performance of malaria nets
Insecticide-treated bed nets remain one of the most effective tools in malaria prevention, acting both as a physical barrier and as an insecticidal surface that kills or disables mosquitoes before they can transmit disease. ...
Phys.org / Keeping up with the phages: How V. cholerae neighbors swap defenses against viruses
Like most bacteria, Vibrio cholerae lives under constant attack from viruses. To survive, bacteria equip themselves with antiviral immune systems. Previous work has shown that V. cholerae carries a large genetic element called ...
Phys.org / What if dark matter came in two states?
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...
Phys.org / No more giants, no more heavy handaxes: Why early humans downsized their stone tools
For more than 1 million years, early humans in the Levant region of the eastern Mediterranean used a range of heavy tools, such as massive handaxes and stone balls, for important tasks, including processing animal carcasses. ...
Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began
Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
Phys.org / Why treelines don't simply rise with the climate
A global study by the University of Basel, Switzerland, reveals a surprising picture: While 42% of treelines worldwide are shifting upslope, 25% are retreating. This seemingly contradictory trend involves more than just warming. ...
Phys.org / Dragonflies share humans' red-light sensing trick, detecting wavelengths near 720 nm
Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study from Osaka Metropolitan University (OMU) has found that dragonflies sense red light similarly to mammals, ...
Phys.org / Single-shot imaging captures more information about ultrafast microscopic processes than previously possible
Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a powerful new tool to observe ...
Phys.org / Great apes mirror facial expressions with surprising precision, study shows
New research from the University of Portsmouth has found that great apes exhibit exactness in mimicking one another's facial expressions in social contexts. The study, published in Scientific Reports, explored how orangutans ...
