The basics of photosynthesis are something that every student learns in school: carbon dioxide, water and light in; oxygen and sugar for growth out. In a world where atmospheric carbon dioxide levels are rising, it is plausible ...

The low-latitude highlands region of southwestern China experienced two major climate events in recent years: a severe drought in 2009–2010 and an extreme heat wave in 2019. Though both sprang from similar large-scale atmospheric ...

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its neighboring galaxy, it ...

Plastics are not inert: they gradually break into fragments over time, forming micro- and then nanoplastics (i.e., particles

For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is published in Nature Communications ...

Dr. David Schwimmer, an expert on the giant North American crocodilian genus Deinosuchus and a Columbus State University geology professor, has contributed his research to the creation of the first-ever scholarly accurate, ...

Researchers from the High Energy Nuclear Physics Laboratory at the RIKEN Pioneering Research Institute (PRI) in Japan and their international collaborators have made a discovery that bridges artificial intelligence and nuclear ...

Though ice sheet melting is widely talked of and debated, there is limited knowledge about what happens after the period of melting. Researchers dig into this "after" period and see how it relates to previous patterns.

Ribosomes—the tiny factories that build proteins in our cells—don't all work with the same efficiency. Researchers from Japan have discovered that ribosomes actually compete with one another, and those that perform poorly ...

Researchers from Yunnan University, the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences, and the National Astronomical Observatory of Japan have unveiled new insights into the fragmentation mechanisms ...

A multinational scientific team led by UiT has uncovered the deepest known gas hydrate cold seep on the planet. The discovery was made during the Ocean Census Arctic Deep–EXTREME24 expedition and reveals a previously unknown ...
