When more rivals are around, they create and add extra protein to their seminal fluid making it extra potent. This boosts the number of offspring their partners produce, but the extra effort comes at a cost: it tires the male out and makes him sluggish to remate. It previously wasn’t […]

Sharks don’t only have powerful jaws. They also have enviably strong spines. Their spines constantly flex when they swim, but never wear out during the fish’s lifetime. Human bones, however, cannot endure the same kind of bending and become more fragile as people age. Northwestern Medicine scientist Stuart Stock is […]

A study from Vanderbilt-Ingram Cancer Center and the Department of Veterans Affairs led by Anna Vilgelm, MD, PhD, and Ann Richmond, PhD, has identified a possible second-line treatment for melanoma patients. The potential treatment would render CDK4/6 inhibitors, a class of drugs prescribed for some breast cancers, also effective against […]

Metastasis, in which cancer cells break free from the primary tumor and form tumors at other sites, worsens the prognosis for many cancer patients. The lymph nodes — glands of the immune system located throughout the body — are typically the traveling cells’ first destination. Now, researchers have developed a […]

You’ve probably heard someone say, “Eat your carrots, they’re good for your eyes.” You may have also seen advertisements for nutritional supplements for eye health. What minerals and vitamins benefit your eyes most? A few nutrients can help maintain eye function, protect against harmful light and reduce the development of […]

Experts from the University of Alberta and two universities of California are teaming up to launch the world’s first open-source database for spinal cord injury research. The Open Data Commons for preclinical Spinal Cord Injury research (ODC-SCI) will improve research and treatment worldwide by making data more accessible, according to […]

Purdue aerospace engineer Alexey Shashurin assisted in the development of the Canady Helios Cold Plasma System and Scalpel, which has been approved by the FDA for use in clinical trials.

More than three decades of research on Alzheimer’s disease have not produced any major treatment advances for those with the disorder, according to a UCLA expert who has studied the biochemistry of the brain and Alzheimer’s for nearly 30 years. “Nothing has worked,” said Steven Clarke, a distinguished professor of […]

In the battle of the sexes, males appear to have the innovative edge—from a genetic standpoint, at least. Scientists are finding that the testes are more than mere factories for sperm; these organs also serve as hotspots for the emergence of new genes, the raw material for the evolution of […]

Visit any drugstore and you’ll find a dizzying array of choices for skin-care products. That’s no surprise, says UC San Francisco dermatology professor Peter Elias, MD, since at least half of Americans, maybe more, have sensitive skin or a diagnosed skin condition such as eczema, atopic dermatitis or rosacea. But […]

Mice scurry around while foraging for food, but genetics may be the unseen hand controlling these meandering movements. Researchers at University of Utah Health are using machine learning to draw links between genetic controls that shape incremental steps of instinctive and learned behaviors. The results are available online in Cell Reports. “Patterns of […]

For a guy who studies other people's stress for a living, Robert-Paul Juster certainly seems to handle it well himself.
