CRISPR method for conditional gene regulation

A team of engineers at the University of Delaware has developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene regulation. Their method, described ...

A molecular look at nascent HDL formation

Oil and water don't mix. But our aqueous blood is full of different types of hydrophobic lipids—including cholesterol. In order to travel via the bloodstream, those lipids need to hitch a ride on an amphipathic carrier. ...

Understanding how plants use sunlight

Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess ...

Sweet lysine degradation

Researchers from the Departments of Chemistry and Biology at the University of Konstanz have gained fundamental new insights into the degradation of the amino acid lysine—carcinogenic oncometabolites as intermediate products

Creating rings in natural antibiotic synthesis

Scientists at the University of Bristol have revealed the secrets of the key ring forming cascade in the biosynthesis of a globally used antibiotic. They hope their findings could lead to the development of antibiotics with ...

How does potassium enter cells?

For decades, it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers at Goethe University Frankfurt and University Groningen have ...

DNA origami full of potent anticancer agents

One of the most successful techniques to combat multidrug resistance in cancer cells is the downregulation of those genes responsible for drug resistance. Chinese scientists have now developed a nanoplatform that selectively ...
