Irreversible hotter and drier climate over inner East Asia

Researchers warn that heatwaves and concurrent droughts of Mongolia's semi-arid plateau have increased significantly during the past two decades, with troubling implications for the future. The change also has ramifications for atmospheric conditions across the Northern Hemisphere.

Scientists reveal regions of the brain where serotonin promotes patience

In a study on mice scientists pinpoint specific areas of the brain that individually promote patience through the action of serotonin.

A route for avoiding defects during additive manufacturing

Research reveals how pores form during metals additive manufacturing and become defects trapped in solidifying metal. The practical value of this research is that it can inform industry on how to predict and improve 3D printing processes.

Research shows bariatric surgery may reduce severity of COVID-19 in patients with obesity

A new study shows that among patients who have obesity and who tested positive for COVID-19, a past history of bariatric surgery was significantly associated with a lower risk of hospital and intensive care unit admission.

SARS-CoV-2 mutations do not appear to increase transmissibility

None of the mutations currently documented in the SARS-CoV-2 virus appear to increase its transmissibility in humans, according to a new study.

How dolphins avoid 'the bends'

New evidence indicates that dolphins are able to consciously slow down their heart rates when preparing to dive, and can even adjust their heart rates according to the length of their intended dive. This allows them to conserve oxygen and adjust their body to the changing pressure as they dive, therefore avoiding issues such as ''the bends''.

New insights into how the CRISPR immune system evolved

Although CRISPR-Cas has found many uses in biotechnology and medicine, it originates in nature, where it functions as a microbial immune system. Scientists shed new light on how CRISPR-Cas emerged early during the development of life on Earth, as well as how this immune system is constantly adapting to new challenges.

Scientists design model to predict cellular drug targets against COVID-19

A computational model of a human lung cell has been used to understand how SARS-CoV-2 draws on human host cell metabolism to reproduce. This study helps understand how the virus uses the host to survive, and enable drug predictions for treating the virus to be made.

Exploring links between infant vocabulary size and vocal interactions with caregivers

Analysis of recordings from infants' homes reveals that certain types of vocal interactions between adults and infants are associated with a larger infant vocabulary.

Obesity is not only the individual's responsibility

Analysis of survey results has revealed that in women, obesity is linked to various social and economic factors. In addition, this study is the first in Japan to illuminate the connection between abuse during childhood and obesity in adulthood. These results highlight the importance of taking these factors into account when implementing policies to...
