CRISPR technology shown to dial down gene activity in bacteria

In a series of experiments with laboratory-cultured bacteria, Johns Hopkins scientists have found evidence that there is a second role for the widely used gene-cutting system CRISPR-Cas9—as a genetic dimmer switch for CRISPR-Cas9 ...

Astronomers detect an outbursting young stellar object

By analyzing datasets from the Palomar Gattini InfraRed survey (PGIR) and NASA's NEOWISE spacecraft, astronomers have identified an outbursting young stellar object (YSO) in the star-forming region NGC 281-W. The study, which ...

Model analyzes how viruses escape the immune system

One reason it's so difficult to produce effective vaccines against some viruses, including influenza and HIV, is that these viruses mutate very rapidly. This allows them to evade the antibodies generated by a particular vaccine, ...

Antibiotic resistance from random DNA sequences

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely ...

In situ sequencing of the fully structured genome

There is a sense in which the information encoded in a gene sequence can be represented by two bits per base pair location. The reality, however, is that this is far from a complete description. Although many academically ...

DeepTFactor predicts transcription factors

A joint research team from KAIST and UCSD has developed a deep neural network named DeepTFactor that predicts transcription factors from protein sequences. DeepTFactor will serve as a useful tool for understanding the regulatory ...
