This research letter documents bone cancer in a 240-million-year-old stem-turtle from the Triassic period, helping to provide more data about the history of cancer in tetrapod evolution. This is a case study about a highly malignant bone tumor on the femur of a shell-less stem-turtle.
An analysis of the 15 highest ranked social sciences and public health universities in the US, UK, and Canada show that clear gender and ethnic disparities remain at the most senior academic positions, despite numerous diversity policies and action plans in place at these universities.
Almost three quarters (70 percent) of biomedical research papers do not report outcomes for men and women, according to a new analysis of over 11.5 million medical research papers published between 1980 and 2016. Additionally, female authors were more likely to report on sex-differences, highlighting that diversity in the workforce -- as well as the research population -- is essential to produce the most rigorous and effective research.
Researchers from Georgia Institute of Technology, University of California San Diego and Massachusetts Institute of Technology have reported new findings about perovskite solar cells that could lead the way to devices that perform better.
The weather these days is wild and will be wilder still within a century. In part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A study published today in Nature is the first to simulate the effects, under current climate policies, that the two melting ice sheets will have on ocean temperatures and circulation patterns as well as on air temperatures by the year 2100.
After reconstructing southern Greenland's climate record over the past 3,000 years, a Northwestern University team found that it was relatively warm when the Norse lived there between 985 and 1450 C.E., compared to the previous and following centuries.
Our actions are guided by moral values. However, monetary incentives can get in the way of our good intentions. Neuroeconomists at the University of Zurich have now investigated in which area of the brain conflicts between moral and material motives are resolved. Their findings reveal that our actions are more social when these deliberations are inhibited.
The grandchildren of adolescent mothers have lower school readiness scores than their peers, according to a study published Feb. 6, 2019, in the open-access journal PLOS ONE by Elizabeth Wall-Wieler of Stanford University, USA, and colleagues at the University of Manitoba.
At least 200 species of large animals are decreasing in number and more than 150 are under threat of extinction, according to new research that suggests humans' meat consumption habits are primarily to blame.
