Researchers expand the known defensive abilities of CRISPR–Cas systems

Viruses can infect bacteria and archaea, just as they can humans. These microbes have evolved their own immune defense mechanisms to combat their pathogens. Bacterial defenses, like CRISPR-Cas systems, contain a variety of proteins and functions that aid bacteria in protecting themselves from foreign intruders.

The detrimental effects of alcohol consumption during pregnancy

For the first time, researchers at the University of Helsinki in Finland examined the effects of prenatal alcohol exposure on the epigenome and gene function of the placenta. The epigenome is a molecular coating on a DNA strand that controls how genes are expressed.

Improving cancer immunotherapies with bioengineered synthetic gene circuits

In two distinct studies, scientists show how synthetic biology can be used to address a challenging problem in cancer immunotherapy: the way immunotherapy-related approaches focused on the short-term killing of tumor cells could fail to eradicate tumors because tumor growth occurs on longer timescales.

RXR: A key protein in the balanced production of different blood cells

In the regulation of hematopoietic stem cells—which are the immature stem cells that produce all the blood cell lineages—the cell protein retinoid X receptor (RXR) is an important element.

Researchers gain insights into how density may change gene expression in some insects

A grasshopper hatched in a crowded environment may look and behave differently than a grasshopper hatched in isolation -; even if they have the same genes.

New biobattery could power ingestible cameras in the small intestine

Tech companies have developed many devices that work outside the body, such as cell phones, smart watches, tablets and hundreds of others. Inside the body, though? That's obviously trickier for several reasons, but power for a device is a big one.

Using CRISPR technology to reduce the symptoms of Huntington’s disease

A neurological condition called Huntington's disease (HD) results in a progressive decline in movement, coordination, and mental ability. It is brought on by a mutation in the huntingtin, or HTT, gene.
