Grey wolf populations have already rebounded in Europe, growing 1,800 percent since the 1960s. Declines in populations of big carnivores like lions, tigers and wolves may be driven more by rapid human economic development than habitat loss or climate change, according to a new study Tuesday. The researchers hope the findings could help to improve …

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have successfully demonstrated that autonomous methods can discover new materials. The artificial intelligence (AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind nanoscale “ladder.” The research was published today in Science Advances. The newly discovered structures were formed by a …

An analysis of 45 million papers and 3.9 million patents since 1945 shows that the rate of disruptiveness in science is steeply declining. Since 1945, the rate of disruptive scientific papers and patents is rapidly declining. This is the conclusion of a recent study, which analyzed 45 million papers and 3.9 million patents. Does this mean that …
With fewer disruptive studies, is science becoming an echo chamber? Read More »
