Cells in the body proliferate at different rates. Some divide constantly and throughout life, like the ones that line the gut. Others divide only rarely, sometimes resting for several years in a non-dividing state. Now, a study led by scientists at MIT's Whitehead Institute sheds light on the molecular mechanisms […]

MIT biologists have discovered an unexpected effect of a ketogenic, or fat-rich, diet: They showed that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a large pool of adult stem cells, which are crucial for keeping the intestinal lining healthy. The […]

Cytokines are a type of proteins that are important to the signaling between cells in the body's immune system, for example in the case of an infection or injury. A new study in the Journal of Allergy and Clinical Immunology, by researchers at Karolinska Institutet and Lund University, is now […]

Fat-soluble statins can prevent liver cancer and reduce mortality in patients with chronic viral hepatitis. These are findings from a study conducted by researchers at Karolinska Institutet in Sweden, among others. The study is published in Annals of Internal Medicine. Chronic viral hepatitis (hepatitis B and C) are severe conditions […]

It’s well established that chronic inflammation can lead to colon cancer, but the molecular mechanisms behind this association aren’t fully understood. Research at Vanderbilt University Medical Center into the role that the signaling protein SMAD4 plays in this process has received funding from the National Cancer Institute. The co-principal investigators […]

Vitamin D deficiency in middle childhood could result in aggressive behavior as well as anxious and depressive moods during adolescence, according to a new University of Michigan study of school children in Bogotá, Colombia. Children with blood vitamin D levels suggestive of deficiency were almost twice as likely to develop […]

As you age your blood pressure is likely to change. That is a normal part of life, which is predictable and can be easily addressed with our current medication. Blood pressure is not to be taken lightly, because it is a major indicator of cardiovascular health. Now a UCL-led research […]

Developing new medicines is notoriously challenging and expensive — especially in cancer. And for academic researchers, there’s limited funding available to advance new ideas to the point where they’re ready to compete for the large-scale federal or foundation funding needed to fully develop them. That’s why the University of Michigan […]

Researchers at University of Utah Health have identified a link between autism and steroid hormone changes detected in the mother’s blood. These changes, which suggest increased estrogen activity, can be seen early in the second trimester. The pilot study, published in the Journal of Autism and Developmental Disorders, opens a new direction in […]

Brain metastases are among the deadliest tumor metastases, with a median survival period of less than one year, and the incidence of brain metastasis is rising. A new Tel Aviv University study finds that melanoma brain metastasis occurs when tumor cells “hijack” an inflammatory pathway in the brain. Blocking this pathway could […]

Some cases of the flu are so severe they cause lasting injury to the lungs. New research from the University of Pennsylvania now points to a strategy that may one day offer protection against this damage. The scientists found that transplanting a certain type of lung cell from healthy mice to […]

Researchers in the University at Buffalo School of Nursing have received two grants totaling more than $260,000 to develop interventions that help young adults quit smoking and improve sleep among people with multiple sclerosis. The projects, led by Eunhee Park, PhD, assistant professor, and Rebecca Lorenz, PhD, associate professor, are […]

In 2006, scientists discovered a way to “reprogram” mature cells – adult skin cells, for example – into stem cells that could, in principle, give rise to any tissue or organ in the body. Many assumed it was only a matter of time until this groundbreaking technique found its way […]

Technique could allow cells to be extracted in real time, help prevent cancer from spreading. Researchers at UCLA and NantWorks have developed an artificial intelligence-powered device that detects cancer cells in a few milliseconds — hundreds of times faster than previous methods. With that speed, the invention could make it […]

The University of Washington School of Medicine and VA Puget Sound Health Care System today announced a two-year partnership to develop new uses of 3D printing to aid in the diagnosis and treatment of complex heart conditions. The collaboration is expected to help cardiologists better visualize the complex anatomy unique […]

Retiring from your full-time job might not be the best thing for your brain as you age, according to a new study out of Florida State University. A team of researchers led by FSU Associate Professor of Sociology Dawn Carr found that people in so-called low-cognitive-complexity jobs, such as truck […]

One of nature’s most familiar phenomena is collective behavior—fish swimming in schools, locusts marching together, birds flocking. The same thing happens in humans, with individual cells synchronizing into circadian rhythms, part of a biological clock that tells our bodies when to eat, sleep or reproduce. How this happens is something of […]

Mothers who drink moderate to high levels of alcohol during pregnancy may be changing their babies’ DNA, according to a Rutgers-led study. “Our findings may make it easier to test children for prenatal alcohol exposure – and enable early diagnosis and intervention that can help improve the children’s lives,” said […]

New insights into why a faulty gene involved in a devastating form of a kidney condition called nephrotic syndrome leads to disease in some patients have been identified in new Kidney Research UK-funded research led by the University of Bristol. The findings, published in the Journal of the American Society […]

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.

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 […]
