All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided between two daughter cells. ...

The halomethane compound bromoform (CHBr3) has devastating effects on the ozone layer. In the upper layers of the atmosphere, bromoform reacts with UV radiation, releasing bromine molecules which destroy ozone molecules. ...

Cases of Borna disease virus 1 (BoDV-1) are extremely rare in humans, but in those who develop disease, the outcome is severe, almost always resulting in fatal encephalitis or inflammation in the brain. This zoonotic virus ...

Rapid ocean warming is likely to make tropical cyclone rainfall more intense and longer lasting, increasing flood risks in parts of the North Atlantic region. A new study led by Newcastle University using satellite data shows ...

Inspired by the collective dynamics of bacteria like E. coli and Bacillus subtilis, researchers at the University of Twente asked a simple but fundamental question: what happens when artificial swimmers are made rod-shaped ...

Mercury released into the oceans affects marine environments worldwide. Traditionally, its distribution and quantity have been estimated using marine biogeochemical simulation models.

A remarkable new discovery is shedding light on one of the greatest survival stories in Earth's history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence ...

For more than 1 million years, early humans in the Levant region of the eastern Mediterranean used a range of heavy tools, such as massive handaxes and stone balls, for important tasks, including processing animal carcasses. ...

Gas separation membranes are vital for carbon capture, biogas upgrading, and hydrogen purification, all of which require the separation of carbon dioxide from gases like nitrogen, methane and hydrogen. However, the membranes ...

Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...

Professor Gyu Rie Lee of the Department of Biological Sciences successfully designed artificial proteins that selectively recognize specific compounds using AI through joint research with Professor David Baker. The research, ...

A global study by the University of Basel, Switzerland, reveals a surprising picture: While 42% of treelines worldwide are shifting upslope, 25% are retreating. This seemingly contradictory trend involves more than just warming. ...
