A team of researchers from the University of Minnesota and University of Massachusetts Amherst has discovered new technology that can speed up chemical reactions 10,000 times faster than the current reaction rate limit. These findings could increase the speed and lower the cost of thousands of chemical processes used in developing fertilizers, foods, fuels, plastics, and more.

In chemical reactions, scientists use what are called catalysts to speed reactions...

Reaction turns CO2 into molecular oxygen. Researchers have demonstrated a new reaction for generating oxygen that could help humans explore the universe and perhaps even fight climate change at home. Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason – we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to come by.

So, when we explore space, we need to bring our own oxygen supply. That is not ideal because a lot of energy is needed to hoist things into space atop a rocket, and once the supply runs out, it is gone.

One place molecular oxygen d...

Researchers have uncovered a wealth of well-preserved meteorites that allowed them to reconstruct the rate of falling meteorites over the past two million years. Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet’s surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a wealth of well-preserved meteorites that allowed them to reconstruct the rate of falling meteorites over the past two million years.

Neurodevelopmental condition can result from mutations in the noncoding regions of the human genome, research shows. Leveraging artificial intelligence techniques, researchers have demonstrated that mutations in so-called ‘junk’ DNA can cause autism. The study, published May 27 in Nature Genetics, is the first to functionally link such mutations to the neurodevelopmental condition.

The research was led by Olga Troyanskaya in collaboration with Robert Darnell. Troyanskaya is deputy director for genomics at the Flatiron Institute’s Center for Computational Biology (CCB) in New York City and a professor of computer science at Princeton University...
