Memory Control

Harvard Medical School researchers based at Massachusetts General Hospital and the Harvard Stem Cell Institute have identified a neural circuit mechanism involved in preserving the specificity of memories. They also identified a genetic “switch” that can slow down memory generalization, the loss of specific details over time that occurs in both age-related […]

Study suggests method for boosting growth of blood vessels and muscle

As we get older, our endurance declines, in part because our blood vessels lose some of their capacity to deliver oxygen and nutrients to muscle tissue. An MIT-led research team has now found that it can reverse this age-related endurance loss in mice by treating them with a compound that […]

Focus on early stage of illness may be key to treating ALS, study suggests

A new kind of genetically engineered mouse and an innovation in how to monitor those mice during research have shed new light on the early development of an inherited form of amyotrophic lateral sclerosis (ALS). An international team of scientists, including four from Brown University, conducted and analyzed tests using […]

Engineered cartilage template to heal broken bones

A team of UConn Health researchers has designed a novel, hybrid hydrogel system to help address some of the challenges in repairing bone in the event of injury. The UConn Health team, led by associate professor of orthopedic surgery Syam Nukavarapu, described their findings in a recent issue of Journal of Biomedical Materials […]

Forgetting details, getting the gist may prompt false memories in older adults

Older adults often complain about forgetting, but Penn State psychologists suggest that another problem may be misremembering. In a study, the researchers found that as people age, they may be more likely to rely on a type of memory — called schematic memory — that helps them remember the gist […]

NIH scientists search for the clocks behind aging brain disorders

To understand the link between aging and neurodegenerative disorders such as Alzheimer’s disease, scientists from the National Institutes of Health compared the genetic clocks that tick during the lives of normal and mutant flies. They found that altering the activity of a gene called Cdk5 appeared to make the clocks […]

Scientists caution that a rare childhood liver cancer can spread to the brain

A surprising finding by Rockefeller University scientists about a rare liver cancer’s behavior could lead to more comprehensive patient monitoring and hopefully better outcomes. The scientists recommend that people with advanced-stage fibrolamellar hepatocellular carcinoma, which mostly affects teenagers and young adults, receive regular neuroimaging scans because of the tumor’s apparent […]

A small protein with many applications

The research team has studied an important protein, called C3, from the part of the innate immune system known as the complement system. Upon recognition of pathogenic organisms or dying cells from our own body, C3 is cleaved by blood enzymes as part of a defence mechanism. These enzymes are […]

Scientists Discover How Gene Mutation Reduces the Need for Sleep

It’s every over-achiever’s dream: a gene mutation that allows them to function normally with just four to six hours of sleep a night instead of the normal eight. In 2009, UC San Francisco neurology professor Ying-Hui Fu, PhD, discovered a mutation in the gene DEC2 in a family of natural short […]

Improved capture of cancer cells in blood could help track disease

Tumor cells circulating throughout the body in blood vessels have long been feared as harbingers of metastasizing cancer — even though most free-floating cancer cells will not go on to establish a new tumor. But if these cast-offs could be accurately counted, they could provide an additional way to track […]

Weak hand grip could be sign of a failing heart

The study, published in the journal PLOS ONE and funded by the British Heart Foundation (BHF), discovered that a weak grip can be associated with changes in the heart’s structure and function, and could be used as a broad measure of someone’s heart health. By asking people to grip a device called a dynamometer […]

Aggressive breast cancer can be transformed into a treatable form

Approximately 10–15 per cent of breast cancer patients have so-called basal breast cancer that do not respond to treatment with hormone therapy, which means that they are more aggressive and often recur. Recent studies emphasise the importance of the communication of cancer cells with other cell types in the surrounding […]

Mind-controlling molecules from wasp venom could someday help Parkinson’s patients

After being stung by a parasitic wasp, the American cockroach loses control of its behavior, becoming host to the wasp’s egg. Days later, the hatchling consumes the cockroach alive. While this is a gruesome process for the cockroach, scientists report in ACS’ journal Biochemistry the discovery of a new family of peptides […]

New study shows how multimorbidity restricts life in the elderly

A progressive decline in physical function, commonly referred to as functional decline, is a strong health determinant in older people. The accumulation of chronic diseases, multimorbidity, plays a major role in functional decline and has a negative impact on quality of life. Cardiovascular and neuropsychiatric diseases are common in older […]
