Supplement treats schizophrenia in mice, restores healthy “dance” and structure of neurons

A simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia. After additional experiments, including visualizing the fluorescently stained dancing edge of immature brain cells, researchers concluded that the supplement likely protects proteins that build neurons’ cellular skeletons. The supplement betaine was first isolated from […]

New Algorithm Uses Online Learning for Massive Cell Data Sets

The method enables researchers to analyze millions of cells with the amount of memory found on a standard computer. The fact that the human body is made up of cells is a basic, well-understood concept. Yet amazingly, scientists are still trying to determine the various types of cells that make […]

Specialized technique captures unique protein structures in neuropathy disorders

Charcot Marie Tooth and Dejerine-Sottas syndrome are groups of diseases that involve the breakdown of the myelin sheath covering nerve axons. As this myelin sheath breaks down, people who have these disorders suffer nerve damage in the arms and legs—those with Dejerine-Sottas disease may never walk or may lose the […]

Omega-3 supplements do double duty in protecting against stress

A high daily dose of an omega-3 supplement may help slow the effects of ageing by suppressing damage and boosting protection at the cellular level during and after a stressful event, new research suggests. Researchers at Ohio State University found that daily supplements that contained 2.5 grams of omega-3 polyunsaturated […]

COVID-19 Data Shows the Importance of Thymic Atrophy in Aging

The decline of the immune system is of great importance in aging. Vulnerability to infection, a decreased surveillance of senescent cells and cancerous cells, and growing chronic inflammation all take their toll. A sizable fraction of this problem stems from the diminished supply of new T cells of the adaptive […]

Cancer cells may evade chemotherapy by going dormant

Cancer cells can dodge chemotherapy by entering a state that bears similarity to certain kinds of senescence, a type of “active hibernation” that enables them to weather the stress induced by aggressive treatments aimed at destroying them, according to a new study by scientists at Weill Cornell Medicine. These findings […]

Excess blood sugar promotes clogging of arteries: study

Excess sugar in the blood, the central feature of diabetes, can react with immune proteins to cause myriad changes in the immune system, including inflammatory changes that promote atherosclerosis, according to a new study from scientists at Weill Cornell Medicine and University of Massachusetts Medical School. The study, published in […]

Radiation may contribute to personalized cancer vaccine

Radiation therapy appears to increase the expression of genes with mutations that induce an immune response to malignant cells, according to preclinical research by Weill Cornell Medicine and NewYork-Presbyterian investigators. The findings suggest that radiation treatment directed to tumors in mice may help to improve a form of immunotherapy that […]

Sweet rewards valued more, may contribute to obesity

Next time you reward a child with a treat, consider offering fruit, nuts or a cereal bar instead of ice cream or candy, a Cornell economist suggests. Research by an international team including Michèle Belot, professor in the Department of Economics, found that children valued a sweet food more after receiving […]

Dietary cocoa improves health of obese mice; likely has implications for humans

Supplementation of cocoa powder in the diet of high-fat-fed mice with liver disease markedly reduced the severity of their condition, according to a new study by Penn State researchers, who suggest the results have implications for people. Cocoa powder, a popular food ingredient most commonly used in the production of […]

„Fat Jam“ in the Cell

In the journal “Nature Communications”, scientists of the German Center for Neurodegenerative Diseases (DZNE) report new findings on the mechanisms of “Niemann-Pick type C disease” (NPC). This rare brain disorder mainly manifests in childhood and includes severe neurological and psychiatric symptoms. Researchers led by Dr. Sabina Tahirovic have now found […]

Attacking Aortic Aneurysms Before They Grow

A new study investigates a genetic culprit behind abdominal aortic aneurysm, a serious condition that puts people at risk of their aorta rupturing – a potentially deadly event. Finding a viable genetic target for AAA could change the game, says senior author Katherine Gallagher, M.D., a vascular surgeon and an associate professor of […]

Women seeking help for unmet needs often overdue for cervical cancer screenings

More than half of cervical cancer cases in the United States occur in women who have not had timely Pap smears and/or HPV tests — screenings that allow for detection of precancerous or cancerous cells on the cervix. Encouraging low-income women, in particular, to participate in such screenings likely would […]

Are you sure you heard that sound?

A new study from Cold Spring Harbor Laboratory (CSHL) Research Investigator Katharina Schmack and Adjunct Professor Adam Kepecs uncovered how hallucinations are produced in human and mouse brains. Their new mouse model for hallucination-like behaviours should help uncover mechanisms and treatments for schizophrenia. Schmack was working as a psychiatrist at the Charité–Universitätsmedizin Berlin […]

Peptide ‘Trojan Horse’ Shows Promise in Preventing Heart Failure

For a while now, heart disease researchers have known that a protein called GRK5 – expressed throughout the body, though most notably in the lungs, heart, and placenta – normally dwells in the outer membrane of heart cells and, upon exposure to stress, moves into the cell nucleus, switching on […]

Treating Sleep Apnea Lowers Dementia Risk By 20-30%

The results of this epidemiological study suggest that suffering from untreated sleep apnea can raise the risk of later dementia and mild cognitive impairment by 20-30%. How the repeated hypoxia in the brain produced by sleep apnea results in a raised risk of dementia isn't understood in detail, but it […]

New CRISPR Technology Offers Unrivaled Control of Epigenetic Inheritance

Scientists have figured out how to modify CRISPR’s basic architecture to extend its reach beyond the genome and into what’s known as the epigenome – proteins and small molecules that latch onto DNA and control when and where genes are switched on or off. In a paper published in the […]

Metabolic switch may regenerate heart muscle following heart attack

Research from the University of Wisconsin–Madison finds that a new therapeutic approach for heart failure could help restore cardiac function by regenerating heart muscle. In a study recently published in the journal Circulation, the UW team describes its success in improving, in a mouse model, the function of heart muscle by […]

Advanced microscopy technique could help UW reach new frontiers in the biosciences

At its most basic level, it takes pictures. For UW–Madison biochemistry professor Elizabeth Wright, that’s the scaled-down explanation of cryogenic electron microscopy or cryo-EM. But it’s so much more than that. Through rapid freezing, controlled beams, and advanced lenses, this game-changing research tool reveals the intricate architecture of cells, viruses, and […]
