Researchers are set to decipher the genomes of a main bacterial cause of food poisoning, which results in over 21,000 hospital admissions and 100 deaths each year.
A new study conducted by sleep and systems biology researchers has found that the daily rhythms of many genes are disrupted when sleep times shift.
Scientists have discovered that two genes linked to hereditary Parkinson’s disease are involved in the early-stage quality control of mitochondria.
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.
A large global team of reproduction experts has found a way to even the score for older women seeking pregnancy using a process called preimplantation genetic diagnosis (PGD).
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.
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.
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.
In 2009, the first face transplant was performed at Brigham and Women’s Hospital, and lead surgeon, Dr. Bohdan Pomahac has been pioneering the procedure since. However, understanding the challenges, particularly around how the recipient accepts or rejects the donated face, is just beginning. Following any transplant, including facial transplant, T cells in the recipient mount an immune response to the donated tissue, threatening rejection.
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.
Exercises meant to boost mental sharpness can benefit older adults as many as 10 years after they received the cognitive training, researchers said. A multi-institutional team of researchers reported that older adults who had participated in the mental exercise programs reported less difficulty with everyday tasks of living than were those who had not participated, even after 10 years had passed.
High concentrations of serum long-chain omega-3 fatty acids may help reduce the risk of type 2 diabetes, according to a University of Eastern Finland study. The sources of these fatty acids are fish and fish oils. The Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) determined the serum omega-3 fatty acid concentrations of 2,212 men between 42 and 60 years of age at the onset of the study, in 1984–1989.
A comparison of Y chromosomes in eight African and eight European men dispels the common notion that the Y‘s genes are mostly unimportant and that the chromosome is destined to dwindle and disappear.
A new study suggests that activating the tumor suppressor p53 in normal cells causes them to secrete Par-4, another potent tumor suppressor protein that induces cell death in cancer cells.
Researchers have developed a technique which can pinpoint the factors which drive cell differentiation, including many that were previously unidentified. The method uses stem cells with a single set of chromosomes to uncover how cell differentiation works.
Researchers have found a new role in stemming bleeding and preventing obstruction of blood flow, explaining the need for speed in busting harmful clots.
Researchers have now developed a novel approach to study the ways in which genetic differences affect how strongly certain genes are "expressed"— that is, how they are translated into the proteins that do the actual work in cells.
Researchers have revealed a new, powerful technique to visualize the shape and motion of RNA at the atomic level using nuclear magnetic resonance spectroscopy (NMR).
Artificial bone marrow may be used to reproduce hematopoietic stem cells. A prototype has now been developed by scientists. The porous structure possesses essential properties of natural bone marrow and can be used for the reproduction of stem cells at the laboratory.
Researchers have taken an important step toward improving the success of hand, face and other transplants that involve multiple types of tissue. The team described how a procedure to induce immune tolerance to organ transplants also induces tolerance to a model limb transplant in miniature swine.
Researchers have mapped genetic variations associated with an increased risk of multiple sclerosis (MS) and myasthenia gravis (MG), bringing science one step closer to understanding these serious autoimmune disorders.
Scientists have published new findings on a system in the brain, known as the nociceptin system, which naturally moderates the effects of stress.
