Many cases of dementia may arise from non-inherited DNA ‘spelling mistakes’

Only a small proportion of cases of dementia are thought to be inherited – the cause of the vast majority is unknown. Now, in a study published in the journal Nature Communications, a team of scientists led by researchers at the University of Cambridge believe they may have found an explanation: […]

When Is Genetic Testing for Breast Cancer Appropriate?

If you have a family history of breast cancer, you may also be at higher risk of developing the disease. This knowledge can boost surveillance and prevention efforts. One in 8 American women will be diagnosed with breast cancer in her lifetime. Among all cases, about 10 percent are caused by the […]

In pursuit of the elusive stem cell

How does the body renew itself? How do cancer cells use the same or similar processes to form tumors and spread throughout the body? How might we use those processes to heal injuries or fight cancer? A new research program at MIT is tackling fundamental biological questions about normal adult […]

Protein has unique effects on information processing

Our cognitive abilities come down to how well the connections, or synapses, between our brain cells transmit signals. Now new study by researchers at MIT’s Picower Institute for Learning and Memory has dug deeply into the molecular mechanisms that enable synaptic transmission to show the distinct role of a protein that, when mutated, […]

Blood test identifies more treatable cancer mutations than biopsies alone

Researchers from the Abramson Cancer Center found that they could identify significantly more mutations through liquid biopsy instead of a solid tissue biopsy alone—and patients responded favorably to targeted therapies. The findings, published in in JAMA Oncology, show that the addition of liquid biopsy nearly doubled the number of mutations detected compared to what […]

Team simulates how Alzheimer’s disease spreads through the brain

For the first time, scientists have developed a computer simulation of how clumps of defective proteins in neurodegenerative diseases like Alzheimer’s spread through the brain, much of the time in stealth mode, over as long as 30 years. “We hope the ability to model neurodegenerative disorders will inspire better diagnostic […]

The fine print: 3-D-printing cells to produce human tissue

With today’s technology, we can 3-D-print sculptures, mechanical parts, prosthetics, even guns and food. But a team of University of Utah biomedical engineers have developed a method to 3-D-print cells to produce human tissue such as ligaments and tendons, a process that will greatly improve a patient’s recovery. A person […]

Early Alzheimer’s Brain Pathology Linked to Psychiatric Symptoms

UC San Francisco researchers, in collaboration with the unique Brazilian Biobank for Aging Studies (BBAS) at the University of São Paulo, have shown that the earliest stages of the brain degeneration associated with Alzheimer’s disease (AD) are linked to neuropsychiatric symptoms including anxiety, depression, loss of appetite, and sleep disturbances.

Scientists get the drop on the cell's nucleus

A team of physicists has devised a novel strategy that uses naturally occurring motions inside the human cell nucleus to measure the physical properties of the nucleus and its components. The method, which reveals that human nucleoli behave as liquid droplets, offers a potential new means for illuminating the physical […]

Calm the Immune System, Halt Premature Birth

Premature birth is the leading cause of infant death and disability in the U.S., and costs billions in dollars and heartache every year. Now, University of Connecticut researchers reported in Reproductive Sciences a potential treatment that could stop many cases of premature labor and birth in their tracks. UConn Health’s Christopher Nold, […]

Building a Patchwork Brain to Study Neurological Disease

Scientists at UCSF and Boston Children’s Hospital have developed a new technique for making mice with brains that combine the genetics of two different mouse strains. The authors aim to use this technique to learn more about how brain cancers form, about how genetic alterations in different parts of the […]

‘Cancer in all forms is our enemy’

Since he took the reins of the Abramson Cancer Center in July 2017, there hasn’t been one day where Robert H. Vonderheide hasn’t felt a thrill. “This place is on fire,” he says. “Drugs are being approved, there are new discoveries, we are excited by all the Nature, Science, and Cell papers. People are flocking here to find […]

Immune cells involved in triple-negative breast cancer could offer future therapeutic target

About 15 percent of breast cancers are classified as triple-negative, lacking receptors for estrogen, progesterone, and Her2. These cancers do not respond to targeted hormonal therapies, and they tend to be particularly aggressive, often resisting systemic chemotherapy and metastasizing to other tissues. Researchers had observed that triple-negative breast cancer (TNBC) […]

Students want to combat Alzheimer’s with light

A newly developed light seeks to reduce degradation of the brain in patents with Alzheimer’s disease. The technology has been approved, a company has been founded, and clinical trials await. A dramatic breakthrough in the treatment of patients with Alzheimer’s may be underway at DTU. For 18 months, a group […]

Study to explore how cognitive development shapes attitudes about physical activity

Even though we know the benefits of physical activity, many of us would rather watch TV than exercise. The reason we avoid working out may stem from our childhood experiences. Iowa State University researchers are working to understand how the emotional connection we develop with physical activity as children influences […]

‘10,000 Immunomes’ Database Opens a Window on Healthy Immunity

Scientists at UC San Francisco have painstakingly assembled a searchable database of normal human immunity that researchers can now use as an instant comparison group in studies of the immune system and immune dysfunction. The new open-access data tool, called the 10,000 Immunomes Project (10KIP), pieces together the results of […]

New immunotherapy offers potential cure for advanced pancreatic cancer

The new cell-based immunotherapy, which has not yet been tested in humans with pancreatic cancer, led to mice being completely cancer-free, including cancer cells that had already spread to the liver and lungs. Each year around 9,800 people in the UK are diagnosed with pancreatic cancer. The disease is particularly […]
