Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

Study evaluates the risk posed by the fungus Bd to amphibians across the continent of Africa

Mass fungus infections that drive populations worldwide to near-collapse don't just occur in science fiction. Chytridiomycosis, the worst vertebrate disease in recorded history, has already wiped out hundreds of species of amphibians around the world. Due to a large part to this fungal disease, 41% of amphibians are currently threatened with extinction. Only species living in Africa seemed to have been relatively spared from the scourge of chytridiomycosis – at least so far.

Transforming the natural mineral shells of algae into functional perovskites

Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

CRISPR/Cas method could help save rice crops threatened by climate change

A review of gene editing techniques suggests that the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/Cas) method could be a possible 'savior' for rice crops threatened by climate change and high food demand.

Uncovering the complete 3D structure of p53 protein

By inducing cell repair or self-destruction, the tumor suppressor protein p53, often known as “the guardian of the genome,” shields the body’s DNA from daily stress or long-term damage.

Study elucidates the cellular changes caused by exposure to adversity during childhood

A new brain connection discovered by University of California, Irvine researchers can explain how early-life stress and adversity trigger disrupted operation of the brain's reward circuit, offering a new therapeutic target for treating mental illness. Impaired function of this circuit is thought to underlie several major disorders, such as depression, substance abuse and excessive risk-taking.
