Four year $1.4 million Air Force grant supports WVU biologists to explore moths’ olfactory systems

As humans walk and talk, we sense our own movements or sounds. Yet, we can distinguish our actions from everything else in our environment that affects our senses.

Newly-discovered mutation highlights complex genetic network that underpins blood disorder

Porphyrias, a group of eight known blood disorders, affect the body's molecular machinery for making heme, which is a component of the oxygen-transporting protein, hemoglobin. When heme binds with iron, it gives blood its hallmark red color.

Inflammation originating from abdominal fat precedes development of sleep apnea, findings suggest

Inflammation is traditionally thought of as a symptom of sleep apnea, but it might actually precede the disorder, potentially opening the door for new ways to treat and predict sleep apnea, according to researchers.

Researchers identify cytotoxic nature of two-dimensional black phosphorous

When environmental and soil chemist Baoshan Xing at the University of Massachusetts Amherst began reading in 2014 that a new, two-dimensional material known as layered black phosphorous (BP) was gaining the attention of biomedical researchers for use in drug delivery systems and tumor photothermal therapy, he was both intrigued and concerned.

Olfactory tissue regeneration requires inflammatory processes that create loss of smell

In a mouse study designed to understand how chronic inflammation in sinusitis damages the sense of smell, scientists at Johns Hopkins say they were surprised to learn that the regeneration of olfactory tissue requires some of the same inflammatory processes and chemicals that create injury and loss of smell in the first place.

Researchers find increase in adverse birth outcomes due to high levels of pesticide exposure

Although common opinion holds that exposure to pesticides increases adverse birth outcomes, the existing body of scientific evidence is ambiguous. Logistical and ethical barriers -- pesticide use data are not widely available and randomized control trials are impossible -- have gotten in the way of more accurate conclusions.

Study examines link between flame retardants and pregnancy outcomes in women undergoing fertility treatments

Women with higher urinary concentrations of a common type of flame retardant had reduced likelihood of clinical pregnancy and live birth than those with lower concentrations, according to researchers at Harvard T.H. Chan School of Public Health.

Study reveals impact of flame retardants on reduced clinical pregnancy outcomes

A study conducted by a team of researchers at the Harvard T.H. Chan School of Public Health has found that for women with an increased concentration of a common type of flame retardant in their urine, there is a decreased possibility of clinical pregnancy as well as live birth when compared to those with a lower concentration.

Scientists develop new attract-and-kill technique to eradicate mosquitoes

Mosquitoes aren't just blood thirsty. They also have a sweet tooth, relying on plant nectar to get the sugar they need to survive. Exploiting this weakness, scientists have developed an environmentally friendly eradication method.

New high-throughput technique accelerates chemical screening to prioritize toxicity testing

Researchers from North Carolina State University have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more.

Study reveals possible medical and industrial properties of avocado seed husks

A new study presented at the 254th National Meeting & Exposition of the American Chemical Society (ACS), suggests that avocado seed husks contain a treasure of unidentified chemical compounds which has the potential to be used in treating various debilitating diseases such as, cancer and heart diseases, as well as in enhancing perfumes, cosmetics and other consumer goods.

Antimicrobial agents in common household products inhibit cell energy, estrogenic functions

A new in-vitro study by University of California, Davis, researchers indicates that quaternary ammonium compounds, or "quats," used as antimicrobial agents in common household products inhibit mitochondria, the powerhouses of the cell, as well as estrogenic functions in cells.

Fruit flies' pheromones reveal sexual attractiveness of females

Life as a fruit fly seems pretty simple: Hatch, grow, eat some fruit, find a mate, produce hundreds of tiny offspring and die -- all in a month or so.
