Scientists identify specific genes associated with post-traumatic stress disorder

A research team has found 18 specific, fixed positions on chromosomes (called loci) that seem to be linked to post-traumatic stress disorder (PTSD).

Study reveals NLRP1 protein that serves as a sensor for invasive pathogens

Researchers are paving the way to a more in-depth understanding of the race between pathogens and the host organisms they search to infect.

Researchers identify key molecule involved in immune regulation

The majority of the molecules in human bodies support the immune system to keep individuals healthy but they do so without reacting excessively, as this may otherwise drive the immune cells to cause problems, like autoimmune disorders.

Ocean acidification could be affecting lobsters on a molecular scale

The American lobster, which supports the most valuable fishery in North America, maybe more susceptible to the effects of climate change than previously thought, according to a new study published in Ecology and Evolution.

Trade restrictions by a few countries could create global food price spikes

Recent events such as the Covid-19 pandemic, locust infestations, drought and labour shortages have disrupted food supply chains, endangering food security in the process.

Study shows TALEN is five times more efficient than CRISPR-Cas9 tool

Using single-molecule imaging, scientists have compared the CRISPR-Cas9 and TALEN genome editing tools.

Study shows how stem cell niche maintain their self-renewal capacity

A typical trait of all stem cells is their potential to renew on their own; however, scientists are unsure about how this ability is sustaining throughout life.

Juicing technique can influence phytochemical content, antioxidant activity of vegetable juices

With the New Year, many people are making resolutions to eat healthier, by eating more vegetables, for example. But those who don't like the taste or texture of some vegetables might prefer to drink them in a home-squeezed juice.

Researchers produce a high-quality reference sequence of the switchgrass genome

Gardeners and farmers around the country recognize that crop varieties grow best in certain regions. Most plant species have adapted to their local environments; for example, crop and ornamental seeds sold for the upper Midwest are often very different than those bred for Texas.

LEAFY protein licenses cell reprogramming to floral fate

Cells don't express all the genes they contain all the time. The portion of our genome that encodes eye color, for example, doesn't need to be turned on in liver cells. In plants, genes encoding the structure of a flower can be turned off in cells that will form a leaf.

Genetic changes in tumors could help predict patient's response to immunotherapy drugs

Researchers at the Francis Crick Institute, the UCL Cancer Institute, and the Cancer Research UK Lung Cancer Centre of Excellence have identified genetic changes in tumours which could be used to predict if immunotherapy drugs would be effective in individual patients.

Unique proteomics-based technology can help diagnose breast cancer more accurately

Breast cancer could be identified more precisely than existing methods using blood specimens and exclusive proteomics-based technology.

Researchers publish a complex genome analysis of switchgrass

Biologists believe they are one step closer to a long-held goal of making a cheap, widely available plant a source for energy and fuel, meaning one of the next big weapons in the battle against climate change may be able to trace its roots to the side of a Texas highway.
