Biological fireworks show 300 million years in the making

Five years ago, researchers at Northwestern University made international headlines when they discovered that human eggs, when fertilized by sperm, release billions of zinc ions, dubbed "zinc sparks."

Machine learning discovers new sequences to boost drug delivery

Duchenne muscular dystrophy (DMD), a rare genetic disease usually diagnosed in young boys, gradually weakens muscles across the body until the heart or lungs fail. Symptoms often show up by age 5; as the disease progresses, ...

Researchers discover new class of chemical reaction

A new study led by Michael P. Burke, assistant professor of mechanical engineering at Columbia Engineering, has identified the significance of a new class of chemical reactions involving three molecules that each participate ...

Researchers create artificial cells that act like living cells

In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that ...

Researchers advance new route to chemically recyclable plastics

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces ...

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 ...
