When a bacterium goes over the top with making a particular gene transcript, it needs a way to degrade that mRNA before it invests too much energy and resources in creating unneeded proteins. A new Observation piece accepted for the inaugural issue of mBio reveals that antisense RNAs may be an ... Read More
A team of scientists based at San Diego State University, the University of Chicago, and the University of South Florida have analyzed all sequence data available in public databases from complete genomes and environmental community genomes, and found out that jumping genes (known as transposase...

Duke Univ. researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology.
They are exploring whether their glassification technique could bring about protein-based drugs that are cheaper to make and ... Read More
It’s wondrous how the vast and the infinitesimal combine to make our planet work. Scientists at Woods Hole Oceanographic Institution (WHOI) have found that bacteria in the ocean, gathering in sort of “microbial block parties,” communicate and cooperate with each other to have a significant impac...

Agricultural researchers at the Hebrew University of Jerusalem are developing an improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones.
The scientists thus hope to offer yet another efficient and promising avenue for supplying ... Read More
Researchers have come up with a new way of sterilising medical equipment - by using a microwave.
Low-cost technology to kill harmful bacteria has been developed at Glyndŵr University in Wrexham.
Researchers found that by attaching a vacuum vessel to a microwave oven, atomic oxygen and ozon... Read More
