Male Infertility New mouse model allows researchers to track defective sperm and potentially find ways to correct it. One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm […]

Can’t remember something? Try waiting until later in the day. Researchers have identified a gene in mice that seems to influence memory recall at different times of day and tracked how it causes mice to be more forgetful just before they normally wake up. “We may have identified the first […]

E-cigarette use significantly increases a person’s risk of developing chronic lung diseases like asthma, bronchitis, emphysema or chronic obstructive pulmonary disease, according to new UC San Francisco research, the first longitudinal study linking e-cigarettes to respiratory illness in a sample representative of the entire U.S. adult population. The study also […]

In recent years, researchers all over the world have been seeking a deeper understanding about the impact of people’s gut bacteria—their so-called microbiome—on their health and risk of developing different diseases. Researchers from the National Food Institute, Technical University of Denmark (DTU), in cooperation with Rigshospitalet, have investigated the microbiome […]

For most of our evolutionary history — for most of the time anatomically modern humans have been on Earth — we’ve shared the planet with other species of humans. It’s only been in the last 30,000 years, the mere blink of an evolutionary eye, that modern humans have occupied the […]

The progression of cancer has been studied extensively, and the key steps in this journey have been well mapped, at least in some solid tumors: Lesions to genes that confer risk of cancer accumulate and alter normal cell behaviors, giving rise, scientists believe, to early-stage cancer cells that eventually swamp […]

It starts off small, just a skin blemish. The most common moles stay just that way — harmless clusters of skin cells called melanocytes, which give us pigment. In rare cases, what begins as a mole can turn into melanoma, the most serious type of human skin cancer because it […]

According to Samuel Tisherman, spokesperson from the University of Maryland, his team of researchers have successfully placed at least one human in suspended animation for the first time in history. The goal of this ground-breaking achievement is to enable medical professionals to fix traumatic injuries such as gunshot or stab […]

Teenage girls who experience clinical levels of anxiety could be at greater risk of eating disorders, according to associations identified in a study completed by researchers at the University of Bristol with UCL.

Reactive oxygen species (ROS), such as free radicals and peroxides, are produced in cells under oxidative stress. Whilst present in healthy cells in small amounts, excessive ROS in cells is damaging and can lead to cancer and neurodegenerative diseases such as Alzheimer’s Disease. The scientists at Bath, collaborating with researchers […]

Hydrogels for healing, synthesized from the molecules up by Rice University bioengineers, are a few steps closer to the clinic. Rice researchers and collaborators at Texas Heart Institute (THI) have established a baseline set of injectable hydrogels that promise to help heal wounds, deliver drugs and treat cancer. Critically, they’ve analyzed […]

In a new paper, researchers at North Carolina State University lift the veil on the “conductor” plant root stem cell gene that helps orchestrate and coordinate stem cell division of different root stem cell types, ensuring the harmonic communication necessary for plant growth and maintenance. Ross Sozzani, an NC State associate […]

One of most potent drugs for treatment of glioblastoma, the most deadly type of brain tumor, can’t be used in patients because of two problems. First, it can’t reach its target because it’s blocked by the blood-brain barrier, a microscopic structure that protects the brain from toxins in the blood. […]

Four months after treating them, Yasuhiro Shiga, MD, PhD, checked on his rats. Walking into the lab, he carried minimal expectations. Treating spinal cord injuries with stem cells had been tried by many people, many times before, with modest success at best. The endpoint he was specifically there to measure […]

By combining RNA sequencing, bioinformatics and mathematical modeling, University of California San Diego School of Medicine and Moores Cancer Center researchers identified a sudden transcriptomic switch that turns healthy liver tissue cancerous. The finding was used to develop a quantitative analytical tool that assesses cancer risk in patients with chronic […]

A recent study shows that people at low genetic risk for attention deficit hyperactivity disorder (ADHD) are not only less likely to have the disorder, they also have better than expected economic, health and behavioral outcomes in later life. The results, published in the journal Psychological Medicine, “capture far more than just […]

A team of researchers at CHU Sainte-Justine and Université de Montréal has discovered a new mechanism involved in a common congenital disease of the aortic valve.
