How the first biomolecules could have been formed

The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this "primordial ...

Exploring monoatomic platinum catalysts

What happens when a cat climbs onto a sunflower? The sunflower is unstable, will quickly bend, and the cat will fall to the ground. However, if the cat only needs a quick boost to catch a bird from there, then the sunflower ...

Scientists discover crystal exhibiting exotic spiral magnetism

An exotic form of magnetism has been discovered and linked to an equally exotic type of electrons, according to scientists who analyzed a new crystal in which they appear at the National Institute of Standards and Technology ...

How metals work together to weaken hardy nitrogen-nitrogen bonds

Nitrogen, an element that is essential for all living cells, makes up about 78 percent of Earth's atmosphere. However, most organisms cannot make use of this nitrogen until it is converted into ammonia. Until humans invented ...

Platinum-free catalysts could make cheaper hydrogen fuel cells

The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency ...
