Figuring out how blank slate stem cells decide which kind of cell they want to be when they grow up— a muscle cell, a bone cell, a neuron— has been no small task for science. Now, a team of researchers has added a new wrinkle to the cell differentiation equation.
Life can be so intricate and novel that even a single cell can pack a few surprises, according to a new study. The pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and rapidly reassemble those pieces when it's time to mate, the study says.
Working with mice, a multicenter team of researchers has found a new way to reduce the abnormal blood vessel growth and leakage in the eye that accompany some eye diseases.
Hundreds of children in about a dozen states have been sickened by a severe respiratory illness that public health officials suspect may be caused by an uncommon virus similar to the germ that causes the common cold.
The United States and Britain plan to send military personnel to help contain West Africa's Ebola outbreak, as the World Health Organization warned Monday that many thousands of new infections are expected in Liberia in the coming weeks.
The National Institutes of Health said it has uncovered a nearly century-old container of ricin and a handful of other forgotten samples of dangerous pathogens as it combs its laboratories for improperly stored hazardous materials.
Key discoveries about breast cancer, Parkinson's disease and the body's handling of defective proteins have earned prestigious medical awards for five scientists. The Albert and Mary Lasker Foundation announced the winners Monday.
A team of investigators has made a thought-provoking discovery about a type of cholesterol previously believed to be a "bad guy" in the development of heart disease and other conditions.
It may look like fresh blood and flow like fresh blood, but the longer blood is stored, the less it can carry oxygen into the tiny microcapillaries of the body, says a new study.
Postmenopausal women who eat foods higher in potassium are less likely to have strokes and die than women who eat less potassium-rich foods, according to new research.
Neurovascular relationships are especially important in the brain. Studies have shown that when neurons work hard, blood flow increases to keep them nourished. Scientists have been asking whether neural activity also changes the structure of local vascular networks. According to new research, the answer is yes.
A doctor who became infected with Ebola while working in Liberia is sick, but in stable condition at the Nebraska Medical Center, officials said Friday.
A popular park in downtown Tokyo has been closed temporarily after dozens of cases of dengue fever were contracted by people who visited the area.
ZMapp, an experimental drug that may have already have saved a few patients in Africa, is the most effective anti-Ebola therapy yet, according to a recent Nature paper on rhesus macaques monkeys.
The way in which some cells alter their behavior at the onset of osteoarthritis has been identified for the first time. Researchers found that changes in the rate at which molecules in joint cartilage called mRNA are created and destroyed are fundamental to causing this change in behavior.
Researchers are investigating markers for potential earlier diagnosis and treatment of Parkinson's disease. The researchers are studying the molecular basis of non-motor symptoms of Parkinson's disease, rather than the better-known clinical symptoms of impaired movement.
Scientists have discovered a new mechanism that can reverse chronic pain. Using an animal model, the research has found that pain signals in nerve cells can be shut off by interfering with the communication of a specific enzyme with calcium channels.
Smoking is banned in more than eight out of 10 U.S. homes— nearly twice as many as two decades ago, according to a new government study. The Centers for Disease Control and Prevention found smoking is even forbidden in nearly half of homes where an adult smoker resides.
An international team of researchers has identified a new inherited neuromuscular disorder. The rare condition is the result of a genetic mutation that interferes with the communication between nerves and muscles, resulting in impaired muscle control.
Sleep difficulties may be linked to faster rates of decline in brain volume, according to a new study. Sleep has been proposed to be “the brain’s housekeeper,” serving to repair and restore the brain.
A pharmacist who oversaw the sterile clean rooms at a Massachusetts compounding pharmacy responsible for a deadly meningitis outbreak was arrested Thursday as he was about to board a flight for Hong Kong, federal officials said.
On this episode of Bioscience Technology This Week, Christina Jakubowski reveals that probing the brain with electric currents can improve memory. Our second story highlights the relationship between individuals and their personalized microbes.
A team of researchers has uncovered an intriguing link between heart attacks and a protein that is of great interest to drug companies for its impact on cholesterol.
Scientists have made an important breakthrough in the fight against debilitating autoimmune diseases such as multiple sclerosis by revealing how to stop cells attacking healthy body tissue.
Cancerous brain tumors are notorious for growing back despite surgical attempts to remove them. But scientists are currently developing a new way to try to root out malignant cells during surgery so fewer or none get left behind to form new tumors.
