From the ability to detect the smell of wet soil to the scent of ripe fruit, the human olfactory system has evolved over thousands of years in response to how people live and what they eat, according to a new genetic study ...

The study of ancient cultures around Ethiopia during the Middle Stone Age (MSA) time period is important for understanding how some of the first Homo sapiens lived and eventually left Africa. Unfortunately, there are not ...

Scientists from Skoltech and the University of Potsdam have developed a physical theory that sheds light on how molecular motors organize the three-dimensional structure of the genome. Using theoretical polymer physics and ...

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their ...

New research led by the University of Houston suggests that formerly incarcerated people are more likely to receive job search assistance if they voluntarily disclose their past while highlighting accomplishments earned during ...

Nearly a week after their Pacific splashdown, the astronauts who crewed the Artemis II mission that flew around the moon told reporters Thursday they have yet to fully grasp the magnitude of the moment.

Scientists from UC San Diego's Scripps Institution of Oceanography and the Centro para la Biodiversidad Marina y la Conservación in Mexico have developed a tool that identifies mangrove patches facing the greatest risk of ...

Physicists in China have simulated the effect of "false vacuum decay": a phenomenon believed to play out constantly in the seemingly empty expanses of space, and which one theory even suggests could bring an abrupt end to ...

If humans or animals eat something that causes them to feel unwell, they subsequently avoid this food source. Until now, it has been unclear precisely how this avoidance learning takes place. A new study shows that communication ...

Powerful cyclones can push seawater miles inland, threatening densely populated communities and critical infrastructure built along coastal areas. A combination of exposure and complexity makes the Bay of Bengal in Southeast ...

Conversational AI tools denied blunt requests for harmful content by researchers posing as intimate partner abusers, but these guardrails were easily circumvented when they requested the content under false pretenses, a new ...
