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.
Nine women in Sweden have successfully received transplanted wombs donated from relatives and will soon try to become pregnant, the doctor in charge of the pioneering project has revealed. The women were born without a uterus or had it removed because of cervical cancer. Most are in their 30s and are part of the first major experiment to test whether it's possible to transplant wombs into women so they can give birth to their own children.
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 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.
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.
Researchers have developed a bio-inspired adhesive that they say can rapidly attach biodegradable patches inside a beating heart— in just the places where holes occur in conditions such as ventricular heart defects.
A rare genetic mutation that disrupts production of histamine in the brain is a cause of the tics and other abnormalities of Tourette syndrome, according to new findings.
The partial model for Obamacare—Massachusetts’ near-universal health care program, adopted in 2006—resulted in measurably improved health. According to a study conducted by researchers from Harvard University and the University of Michigan—with help from the Centers for Disease Control (CDC)—the health of Massachusetts residents rose more in the first five years of the program than did the health of residents in other New England states.
Talk about mind over matter: A quirky new study suggests patients' expectations can make a big difference in how they feel after treatment for a migraine.
We ring in the New Year with hopes of being healthy, wealthy and wise. A new study from epidemiological researchers suggests that health and wealth may be more strongly connected than previously thought.
Researchers have discovered a promising strategy for treating cancers that are caused by one of the most common cancer-causing changes in cells.
A new neuroscience study sheds light on the biological underpinnings of obesity. The in vivo study reveals how a protein in the brain helps regulate food intake and body weight.
Researchers have discovered a possible new target for treating movement disorders such as Huntington’s disease and Parkinson’s disease.
Engineers hope a new type of vaccine they have shown to work in mice will one day make it cheaper and easy to manufacture on-demand vaccines for humans. Immunizations could be administered within minutes where and when a disease is breaking out.
The controversial idea that vertebrate evolution can happen rapidly, in the merest handful of generations, has been given a boost. Harvard University evolutionary geneticist Nicolas Rohner and colleagues recently reported finding the mechanism by which some cavefish are born eyeless after the species moves from surface waters to dark caves.
Anti-smoking measures have saved roughly 8 million U.S. lives since a landmark 1964 report linking smoking and disease, a study estimates, yet the nation's top disease detective says dozens of other countries do a better job on several efforts to cut tobacco use.
Researchers have zoomed in on what is going on at the molecular level when the body recognizes and defends against an attack of pathogens, and the findings, they say, could influence how drugs are developed to treat autoimmune diseases.
In adults, some brain regions retain a “childlike” ability to establish new connections, potentially contributing to our ability to learn new skills and form new memories as we age, according to new research.
A cancer-research team has identified a protein that may be a major culprit when breast cancer metastasizes to the brain. The cancer’s spread to the brain is often undetected until patients start to develop symptoms such as seizures, headaches, and trouble thinking.
By attaching a cancer-killer protein to white blood cells, biomedical engineers have demonstrated the annihilation of metastasizing cancer cells traveling throughout the bloodstream.
