The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis — one of the longest known going back to this period — was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of …

Teens from larger families have poorer mental health than those with fewer siblings, according to a large analysis of children in the United States and China. The details of the pattern vary depending on factors such as the spacing of sibling ages and the age of the siblings. But the fact that the overall pattern …

Oxidative coupling of methane (OCM) is now one step closer to leaving the lab and entering the real world. Researchers have developed an OCM catalyst that exceeds 30 percent when it comes to the production of ethylene. Oxidative coupling of methane (OCM) is now one step closer to leaving the lab and entering the real …
Researchers have developed a unique catalyst that promises to revolutionize drug synthesis. It overcomes a common problem associated with the production of drugs from ketones. Using their catalyst, the researchers synthesized a key component of the commonly used incontinence drug oxybutynin. Their results underscore the potential of the catalyst to improve drug discovery and development. …

Researchers use light-reactive molecules to influence the acidity of a liquid and thereby capture of carbon dioxide. They have developed a special mixture of different solvents to ensure that the light-reactive molecules remain stable over a long period of time. Conventional carbon capture technologies are driven by temperature or pressure differences and require a lot …

The warming climate has not lead to an expected increase in atmospheric moisture over arid and semi-arid regions of the world. The finding, which has surprised scientists, indicates that some regions may be even more vulnerable to future wildfires and extreme heat than projected. The warming climate has not lead to an expected increase in …
