A new brain-imaging technique enables people to "watch" their own brain activity in real time and to control or adjust function in pre-determined brain regions.
The probability of blindness due to the serious eye disease glaucoma has decreased by nearly half since 1980, according to a new study. The researchers speculate that advances in diagnosis and therapy are likely causes for the decrease.
A thickening of the brain cortex associated with regular meditation or other spiritual or religious practice could be the reason those activities guard against depression– particularly in people who are predisposed to the disease, according to new research.
Cancer cells have something that every prisoner longs for— a master key that allows them to escape. A study describes how a protein that promotes tumor growth also enables cancer cells to use this key and metastasize.
Exposing skin to sunlight may help to reduce blood pressure by altering levels of the small messenger molecule nitric oxide (NO) in the skin and blood, thus cutting the risk of heart attack and stroke, a new study says.
Researchers have decoded the genome of the hookworm, Necator americanus, finding clues to how it infects and survives in humans and to aid in development of new therapies to combat hookworm disease.
Researchers have identified a new molecular mechanism by which cocaine alters the brain's reward circuits and causes addiction. The research reveals how an enzyme and synaptic gene affect a key reward circuit in the brain, changing the ways genes are expressed.
As the country settles in for yet another winter full of colds and flu, imagine if your undershirt or socks not only kept you warm but also warned you about an oncoming infection.
Activation of a single type of neuron in the prefrontal cortex can spur a mouse to eat more— a finding that may pinpoint an elusive mechanism the human brain uses to regulate food intake.
New research has uncovered a quality control mechanism in brain cells that may help keep deadly neurological diseases in check for months or years. The research stemmed from two largely unexplained factors for prion infections: their long incubation periods of up to five decades, and a noted time discrepancy between the accumulation of the misfolded rogue prion protein in the brain and when the disease actually shows symptoms.
New findings from the team of Claudine Kraft at the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna give insights into how cells dispose of their waste. Malfunctions in this process have been linked to Alzheimer’s disease and cancer.
The habit of Googling for an online diagnosis before visiting a GP can provide early warning of an infectious disease epidemic. A new study claims internet-based surveillance has been found to detect infectious diseases such Dengue Fever and Influenza up to two weeks earlier than traditional surveillance methods.
MIT neuroscientists have now shown that they can extinguish well-established traumatic memories in mice by giving them a type of drug called an HDAC2 inhibitor, which makes the brain’s memories more malleable, under the right conditions.
New research from Queen Mary University of London has revealed – for the first time – how the condition Giant Cell Arteritis (GCA) may be caused by a certain group of white blood cells called ‘neutrophils’. GCA (also known as temporal arteritis) is a condition which causes severe inflammation in the blood vessels and primarily affects the elderly.
The immune system plays an important role in the heart’s response to injury. But until recently, confusing data made it difficult to distinguish the immune factors that encourage the heart to heal following a heart attack, for example, from those that lead to further damage. Now, researchers have shown that two major pools of immune cells are at work in the heart.
Google unveiled a contact lens that monitors glucose levels in tears, a potential reprieve for millions of diabetics who have to jab their fingers to draw their own blood as many as 10 times a day. The prototype, which Google says will take at least five years to reach consumers, is one of several medical devices being designed by companies to make glucose monitoring for diabetic patients more convenient.
A major mystery in heart disease—why most people who develop serious heart disease have normal blood pressure and cholesterol—may have been solved in a “tremendously significant” study. Some are already calling the study “important” and “frame-shifting.” The study—Multi-Ethnic Study of Atherosclerosis—found that coronary artery calcium scans can often more accurately predict heart disease than cholesterol and blood pressure readings.
Imagine seeing a dozen pictures flash by in a fraction of a second. You might think it would be impossible to identify any images you see for such a short time. However, a team of neuroscientists from MIT has found that the human brain can process entire images that the eye sees for as little as 13 milliseconds — the first evidence of such rapid processing speed.
McGill researchers, led by Dr. Maya Saleh of the Department of Medicine, have identified an enzyme, cIAP2 that helps the lungs protect themselves from the flu by giving them the ability to resist tissue damage. The results of the now suggest that one effective way of countering influenza infections may instead be offered by enhancing the body’s resistance to the virus.
The brain appears to synchronize the activity of different brain regions to make it possible for a person to pay attention or concentrate on a task, scientists have learned. Researchers think the process, roughly akin to tuning multiple walkie-talkies to the same frequency, may help establish clear channels for communication between brain areas that detect sensory stimuli.
The structure of the human brain is complex, reminiscent of a circuit diagram with countless connections. But what role does this architecture play in the functioning of the brain? To answer this question, researchers have for the first time analyzed 1.6 billion connections within the brain simultaneously.
The controversial notion that being overweight might actually be healthier for some people with diabetes — seems to be a myth, researchers report. A major study finds there's no survival advantage to being large, and a disadvantage to being very large.
Biotech drugmaker Amgen and Illumina, a maker of genetic testing equipment, said Wednesday they are developing a test that will identify patients who might be helped by Amgen's colon cancer drug Vectibix. Vectibix is approved as a treatment for colorectal cancer that has spread and hasn't rresponded to chemotherapy.
Immunotherapy—the art and science of training peoples’ immune systems to fight their own cancers—was named Breakthrough of the Year by Science. Prominently mentioned was an approach seeing clinical success: genetically tweaking patients’ own T cells to make them more potent, proliferative, and targeted.
Everybody feels pain differently, and brain structure may hold the clue to these differences. In a new study, scientists at Wake Forest Baptist Medical Center have shown that the brain’s structure is related to how intensely people perceive pain.
