Under the sea ice during the Arctic's pitch-black polar night, cells power photosynthesis on the lowest light levels ever observed in nature.

Research groups led by Prof. Xu Tongwen and Prof. Li Xingya from the University of Science and Technology of China (USTC) have proposed the concept of total dehydration of ions, and prepared metal-organic framework (MOF) confined crown ether membranes, which solved the problem of precise separation of ions in complex systems. The research results were published in Science Advances.

The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are anthropogenic, primarily from fossil fuel burning and other activities in the transportation and agriculture sectors. The remainder of the methane budget comes from…

Dr. Peter Attia explains why these tests are so important.

Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation in older men and women, according to a new study from the University of Eastern Finland.

Hydrogen (H2) is a clean carbon-free fuel with high gravimetric energy density and emerges as an attractive alternative to the unrenewable fossil resource. Photocatalytic water splitting over a semiconductor provides a promising economical and environmentally friendly route to convert unlimited solar energy to H2.

Researchers may have discovered the elusive cure to baldness in an unlikely place: those unsightly hairs that sometimes grow out of skin moles.

Sundyne's Centrifugal and Positive Displacement Compressors are Used Around the Globe in a Wide Range of Process Gas Applications

The heavy use of fossil fuels for driving industrial processes and human activities has resulted in increasingly excessive emissions of anthropogenic CO2 into our atmosphere, surpassing the 400 ppm level. This exceedingly high concentration of atmospheric CO2 has led to a series of negative consequences for our planet's climate system. However, CO2 can be a strategic carbon resource for synthesizing valued…

The science of the perfect second

But intensive glucose control didn't preserve pancreatic C-peptide secretion

To the world's timekeepers, the leap second is a kludge, a bane, a pain in the little hand. Now they're proposing to ditch it. Will our days ever be the same?

Our gastrointestinal system is lined with thick mucus as a barrier to prevent dangerous substances from getting inside. This is why some medicines—insulin, for example—must be injected instead of s…

Olefins are key building blocks to manufacture a wide range of value-added products such as polymers, lubricants, plasticizers, drugs, detergent and cosmetics.

What are antinutrients? We explore what the science says about these compounds and uncover whether or not they actually pose a risk to our health

Carbonating water at home to make seltzer using a CO2 gas supply and ordinary soda bottle

Per- and polyfluoroalkyl substances (known as PFAS) are long-lasting compounds that are showing up in soil, ground water, drinking water sources, even rainfall, and have been linked to cancer, liver damage, thyroid disease, and other ailments.
