Limiting a certain protein in the brain reverses Alzheimer’s symptoms in mice, report neuroscientists at MIT’s Picower Institute for Learning and Memory. Researchers found that the overproduction of the protein known as p25 may be the culprit behind the sticky protein-fragment clusters that build up in the brains of Alzheimer's patients.
Indiana University researchers have detected new early-warning signs of the potential loss of...
Scientists have created a new model of memory that explains how neurons retain select memories a...
In a feat of reverse tissue engineering, Stanford University researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform myriad biological tasks.
Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of defenders that patrol only one area, a single organ, instead of an entire city, the body.
The Food and Drug Administration is warning women that a device-assisted procedure for treating growths in the uterus could inadvertently spread cancer to other parts of the body. The agency is discouraging doctors from performing the procedure, which uses an electronically powered device to...
DUBAI, United Arab Emirates (AP) — A recent spate of infections from a frequently deadly Middle East virus is raising new worries about efforts to contain the illness, with infectious disease experts urging greater vigilance in combatting its spread. More than 20 people, many of them health-care...
Researchers used an MRI-based method to identify and confirm the presence of brown adipose tissue in a living adult, which could prove to be an essential step towards a new wave of therapies to aid the fight against diabetes and obesity.
The Ebola virus that has killed scores of people in Guinea this year is a new strain - evidence that the disease did not spread there from outbreaks in some other African nations, scientists report.
In the midst of the diabetes epidemic, a glimmer of good news: Heart attacks, strokes and other complications from the disease are plummeting. Over the last two decades, the rates of heart attacks and strokes among diabetics fell by more than 60 percent, a new federal study shows. The research...
Teenagers who have suffered a traumatic brain injury such as a concussion are at “significantly greater odds” of attempting suicide, being bullied and engaging in a variety of high risk behaviors, a new study has found.
Cases of diabetes and pre-diabetes in the United States have nearly doubled since 1988, suggests new research, with obesity apparently to blame for the surge.
Psychologists have presented the first study to reveal that our brains rely on an active suppression mechanism to avoid being distracted by salient irrelevant information when we want to focus on a particular item or task.
It’s long been known that certain strains of human papillomavirus (HPV) cause cancer. Now, researchers have determined a new way that HPV might spark cancer development– by disrupting the human DNA sequence with repeating loops when the virus is inserted into host-cell DNA as it replicates.
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.
Using just a single drop of blood, a team of UW-Madison researchers has developed a faster, cheaper and more accurate tool for diagnosing even mild cases of asthma. This handheld technology—which takes advantage of a previously unknown correlation between asthmatic patients and the most abundant type of white blood cells in the body—means doctors could diagnose asthma even if their patients are not experiencing symptoms during their visit.
Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
