The new study used simple multicellular organisms called Placozoa to reveal the beginnings of the nervous systems found in more complex […]

Neurons in the human brain receive electrical signals from thousands of other cells, and long neural extensions called dendrites play a critical role in incorporating all of that information so the cells can respond appropriately. Using hard-to-obtain samples of human brain tissue, MIT neuroscientists have now discovered that human dendrites […]

A new Tel Aviv University study finds that certain environmental conditions may precipitate structural changes that take place in myelin sheaths in the onset of multiple sclerosis (MS). Myelin sheaths are the “insulating tape” surrounding axons; axons carry electrical impulses in neurons. The research demonstrates that myelin sheaths undergo structural transitions when […]

A team from the University of Pennsylvania, Children’s Hospital of Philadelphia, and the University of Wisconsin-Madison are launching a project to develop new strategies for treating vision disorders using cells implanted in the retina.

The development of synthetic tissue […]

Almost eight years ago, Stanford University bioengineer Manu Prakash was looking for a way to watch every cell in an adult living, behaving animal in elaborate detail. He searched the catalog of life and happened upon the simple marine animal Trichoplax adhaerens – or Tplax, as Prakash has come to call it. This ultra-flat […]

A new blood test for children with brain tumors may offer a safe way to allow doctors to measure the effectiveness of treatment even before changes are identified on scans, according to research led by UCSF Benioff Children’s Hospitals and Children’s National Health System. Unlike a standard brain biopsy, which entails […]

A detailed new review of nutritional science argues that most American diets are deficient in a key class of vitamins and minerals that play previously unrecognized roles in promoting longevity and in staving off chronic diseases such as heart disease, cancer and, potentially, neurodegeneration. In the review, published as a […]

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: […]

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 […]

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 […]

Our cognitive abilities come down to how well the connections, or synapses, between our brain cells transmit signals.
