The findings, published in Nature Medicine, show that a substance best known for spurring […]

A new study has identified several key factors in postmenopausal women that are associated with height loss, a common occurrence in this age group that is known to increase the risk for death and disease. One factor goes back to what study participants may — or may not — have […]

With summer coming, it’s only a matter of time before the smells and tastes of barbecued foods dominate the neighborhood. But there’s a downside to grilling that can literally get under your skin. In a study appearing in Environmental Science & Technology, scientists report that skin is a more important pathway […]

The team of researchers has successfully ‘trained’ a respiratory virus to recognise ovarian cancer and completely destroy it without infecting other cells. The reprogrammed virus could also be used to treat other cancers such as breast, pancreatic, lung and oral. Dr Alan Parker from Cardiff University’s School of Medicine said: […]

We know a lot about how genes get passed from parent to child, but scientists are still unraveling how so-called epigenetic information—instructions about which genes to turn on and off—is conveyed from generation to generation. Using the tiny worm Caenorhabditis elegans, a simple and powerful model for uncovering the fundamental workings of […]

Anyone who’s taken a bite of a sandwich with too much spicy mustard or a piece of sushi with too much wasabi can attest to the tear-inducing sensation these condiments can cause. These loud warnings to the nervous system of exposure to potentially harmful chemicals are triggered by TRPA1, a […]

Zebrafish embryos are transparent and develop outside the mother’s body, enabling scientists to get a detailed view of early development. A research team led by Lila Solnica-Krezel, the Alan A. and Edith L. Wolff Distinguished Professor and head of the Department of Developmental Biology at Washington University School of Medicine in St. Louis, […]

A new Tel Aviv University study identifies a previously unknown mechanism involved in the development of Lou Gehrig's disease, or amyotrophic lateral sclerosis (ALS). The research focuses on a specific microRNA whose levels were found to decrease as a result of ALS-causing muscular mutations. The study highlights, for the first time, the […]

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does another decide to build cartilage rather than […]

New clues may help improve speech for people with dysarthria, a type of speech disorder commonly found in patients with amyotrophic lateral sclerosis (ALS). Findings in a study led by Jimin Lee, assistant professor of communication sciences and disorders at Penn State, could aid patients with dysarthria. Dysarthria can cause […]

 A new interdisciplinary research and education center at the University of California, Irvine will apply the power of mathematics to some of the more vexing mysteries in cell biology. The MathBioSys Center on Multiscale Cell Fate is being initiated with $10 million in funding, half from the National Science Foundation […]

The brain's ability to form new neural connections, called neuroplasticity, is crucial to recovery from some types of brain injury, but this process is hard to study and remains poorly understood. A new study of neural circuit repair in the retina shows that neurons can make new connections to the […]

Mammals have bipartite blood circulation, i.e. pulmonary and systemic circulation. The heart is also divided: each circulatory system has an atrium and a ventricle, with the left and right halves of the heart differing in form and function. Scientists from the Max Planck Institute for Heart and Lung Research in […]

Glioblastoma multiforme, a type of brain tumor, is one of the most difficult-to-treat cancers. Only a handful of drugs are approved to treat glioblastoma, and the median life expectancy for patients diagnosed with the disease is less than 15 months. MIT researchers have now devised a new drug-delivering nanoparticle that […]

WEST LAFAYETTE, Ind. – Beta-amyloid peptides, protein fragments that form naturally in the brain and clump into plaques in Alzheimer’s disease patients, are thought to be responsible for neuron death, but it hasn’t been clear how the substances kill cells. Now, a Purdue University scientist has shown through computer simulations […]

Recovery after severe spinal cord injury is notoriously fraught, with permanent paralysis often the result. In recent years, researchers have increasingly turned to stem cell-based therapies as a potential method for repairing and replacing damaged nerve cells. They have struggled, however, to overcome numerous innate barriers, including myelin, a mixture […]

Cranking up your headphones or scrambling for a front-row spot at rock shows could be damaging more than your hearing. New research from The Ohio State University has found that young people with subtle hearing loss – the kind they aren’t even aware of – are putting demands on their […]

Researchers have identified a compound that blocks the spread of pancreatic and other cancers in various animal models. When cancer spreads from one part of the body to another in a process called metastasis, it can eventually grow beyond the reach of effective therapies. Now, there is a new plan […]

A review of the most comprehensive body of evidence on acute lymphoblastic leukaemia (ALL) — the most common type of childhood cancer – conducted by Professor Mel Greaves from the Institute of Cancer Research in London (ICR) indicates the disease is likely caused by genetic mutation coupled with exposure to […]
