Breaking up is hard to do (especially for sex chromosomes)

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the instructions for initiating ...

Have resistance, will travel

Around the world, pest insects like mosquitoes often become resistant to the insecticides meant to control them, causing problems for agriculture and public health.

Microbial cyborgs: Bacteria supplying power

Electronic devices are still made of lifeless materials. One day, however, "microbial cyborgs" might be used in fuel cells, biosensors, or bioreactors. Scientists of Karlsruhe Institute of Technology (KIT) have created the ...

Using DNA-like punch cards to store data

A team of researchers at the University of Illinois and the University of Texas has developed a new way to use DNA as a data storage medium—by using them like punch cards. In their paper published in the journal Nature ...

Research sheds light on how silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the ...

Better plant edits by enhancing DNA repair

A new genome editing system enhances the efficiency of an error-free DNA repair pathway, which could help improve agronomic traits in multiple crops.

Technique reveals how crystals form on surfaces

The process of crystallization, in which atoms or molecules line up in orderly arrays like soldiers in formation, is the basis for many of the materials that define modern life, including the silicon in microchips and solar ...
