Skin, eye and hair pigmentation requires a delicate balance of acidity within the cellular...
Combining two cutting-edge techniques reveals that neurons in the prefrontal cortex are built to...
It is not surprising that a good night’s sleep improves our ability to remember what we learned...
Researchers at Johns Hopkins University School of Medicine have discovered why delaying bedtime causes chronic sleepiness. The results, in fruit flies, may help people with sleep disorders.
Johns Hopkins researchers report they have inadvertently found a way to make human muscle cells bearing genetic mutations from people with Duchenne muscular dystrophy (DMD).
A new study shows how a gene mutation found in several human cancers, including leukemia, gliomas and melanoma, promotes the growth of aggressive tumors.
National Institutes of Health expert reviewers are finding flaws in the agency's new study that connects heavy cell phone radiation to a slight increase in brain tumors in male rats.
Research led by the Achucarro Basque Center for Neuroscience, the University of the Basque Country (UPV/EHU), and the Ikerbasque Foundation has revealed the mechanisms that keep the brain clean during neurodegenerative diseases.
Some species of sea urchins live to extraordinary old ages and -- even more remarkably -- do so with no signs of poor health, such as a decline in regenerative capacity or an increase in age-related mortality.
Scientists have developed a quicker and more efficient method to alter the genes of mice with CRISPR-Cas9, simplifying a procedure growing in popularity because of the ease of using the new gene-editing tool. The new method gets around a time-consuming bottleneck in creating knockout mice: using microscopic needles to inject gene-editing molecules into a fertilized egg.
An antibody, produced by the body's own immune system, preferentially attacks only cancer cells, according to a new study from researchers at Duke University Medical Center. It works by dismantling the cancer cell's defense system.
Scientists have identified a molecular key that breast cancer cells use to invade bone marrow in mice, where they may be protected from chemotherapy or hormonal therapies that could otherwise eradicate them.
A stress receptor in the brain is found to regulate metabolic responses to stressful situations differently in male and female mice.
When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area. Now, researchers describe a new technique that combines the best of both worlds — it captures a detailed snapshot of global activity in the mouse brain.
The fruit fly Drosophila bifurca is only a few millimeters in size but produces sperm that are almost six centimeters long. A team of researchers now provides the first conclusive explanation for the evolution of such giant sperm.
Dogs are an excellent animal model for studying cancer, a recent study published in PLOS Genetics found. The research identified genes that could possibly play a role in the development of brain cancer in both dogs and humans.
Santa Cruz Biotechnology, Inc. has agreed to pay a $3.5 million fine, and revoke its research registration and dealer license in accordance with terms of a legal settlement with the U.S. Dept. of Agriculture.
