Phys.org / Most people cooperate—and underestimate others' willingness to cooperate, global study reveals
The study "Homo cooperans: Understanding the nature of human cooperation" arrives at a clear result: 69% of study participants chose to cooperate. At the same time, the study published in the journal Science shows that people ...
Phys.org / D&D-seq maps DNA-protein interactions in single cells with multi-omics compatibility
A new technology allows scientists to map, in single cells, the DNA binding sites of transcription factors and other regulatory proteins that control gene activity, according to a study led by investigators at Weill Cornell ...
Phys.org / Billions are going into fish passage projects, but planning methods can undercut results
Fish that split their lives between fresh and salt water often face obstacles getting back and forth. Dams and roads fracture river networks and interfere with traditional migratory routes, sparking concerns about fish health ...
Phys.org / Can fighting via text be good for a relationship?
Today, many of our social interactions are routed through technology: text messages, video calls, voice messages, emails and instant messaging apps. In romantic relationships, couples often use these methods to deal with ...
Phys.org / DNA repair enzyme uses one-dimensional sliding to detect key sites, researchers reveal
DNA is the blueprint of the human body. However, tens of thousands of DNA lesions occur in our bodies every day. In particular, if "apurinic/apyrimidinic sites" (AP sites, damaged sites where one letter of DNA information ...
Phys.org / On-demand Arctic observations with low-cost balloon systems could sharpen local storm forecasts
Arctic communities are increasingly exposed to dangerous weather events due to climate change and rely on accurate weather forecasts. However, conditions in the lower atmosphere remain poorly observed in the Arctic because ...
Phys.org / Not too sunny, not too shady, just right for Japanese macaques
As climate change alters the temperatures of animal habitats, it seems natural that endotherms, warm-blooded animals, would prefer to hang out in the shade during hot weather. The use of microhabitats in the sun and shade ...
Phys.org / How honeybees really crown their queens
For generations, scientists believed a queen honeybee was made almost entirely by diet: feed an ordinary larva enough royal jelly and a ruler emerges. But new research suggests queens are created through a more elaborate ...
Phys.org / Extraordinary fossils solve a 500-million-year mystery: Bryozoans were there at the dawn of animal life
Bryozoans are tiny, filter-feeding colonial invertebrates that thrive in the world's oceans today, yet for decades their origins presented a puzzling gap in the fossil record. While nearly every other major animal group made ...
Phys.org / Violating the 3rd law of black hole mechanics in vacuum gravity
Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts ...
Phys.org / Warming unlocks ancient carbon in Tibetan permafrost, triggering climate tipping point
A new study in Nature Communications finds a critical climate tipping point in Tibetan permafrost ecosystems. Warming of 2–4 degrees Celsius triggers a self-reinforcing cycle of carbon release that could significantly accelerate ...
Phys.org / Octopuses learn mirror-guided navigation to locate prey
Octopuses are remarkably intelligent creatures, as was demonstrated by Inky the Octopus's famous escape from the National Aquarium of New Zealand through a drainpipe back to sea in 2016. A new Dartmouth study shows octopuses ...
