Biologists are studying retinal regeneration in zebrafish to find ways to combat human eye diseases. The small, minnow-like fish have eyes that develop in a way very similar to humans, but have the ability to regenerate retinal cells following an injury.
A new study demonstrates that the ‘memory’ of nutrition during pregnancy can be passed through sperm of male offspring to the next generation, increasing risk of disease for grandchildren as well. In other words, to adapt an old maxim, ‘you are what your grandmother ate.’
A new study indicates that middle-aged adults with a history of problem drinking are more than twice as likely to suffer from severe memory impairment in later life.
Researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).
Researchers have found a missing link that helps to explain how ALS, one of the world’s most feared diseases, paralyses and ultimately kills its victims. The breakthrough is helping them trace a path to a treatment or even a cure.
Individuals with major depressive disorder or bipolar disorder who receive low-field magnetic stimulation (LFMS) show immediate and substantial mood improvement, researchers report.
When you're expecting something— like the meal you've ordered at a restaurant— or when or when something captures your interest, unique electrical rhythms called gamma oscillations sweep through your brain. New research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.
Researchers have identified a mechanism that overrides the cells’ warning signals, enabling cancers to continue to divide even without a robust blood supply.
Bioengineers have designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease.
U.S. health officials are monitoring the Ebola outbreak in Africa but say the risk of the deadly germ spreading to the United States is remote. The Centers for Disease Control on Monday sent a health alert to U.S. doctors about the outbreak.
A new research project shows that many adolescents suffer from knee pain for several years. The pain impacts both sporting activities and quality of life.
Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson’s disease, including six that had not been previously reported.
In a massive effort to catalog the molecular causes of stomach cancer, scientists have identified four subtypes of tumors based on shared mutations and other molecular abnormalities.
Microorganisms can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. Now, a new study has shown that microorganisms can use a temporary silencing of drug targets to gain the benefits of drug resistance without the commitment.
A new study has found that turning the thermostat down a few notches at night may expand brown fat tissue mass and activity, which could lead to metabolic benefits such as more effective disposal of glucose.
Two recent studies— one human, one mouse— have found cloning creates better pluripotent stem cells than the Nobel Prize-winning induced pluripotent stem cell (iPSC) method. A third study also came out supporting the conclusions.
Nigerian health authorities raced to stop the spread of Ebola on Saturday after a man sick with one of the world's deadliest diseases brought it by plane to Lagos, Africa's largest city with 21 million people.
When it comes to preventing the spread of germs, maybe the president is on to something with his fondness for fist bumps. The familiar knocking of knuckles spreads only one-twentieth the amount of bacteria that a handshake does, researchers report.
Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers.
The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.
Scientists at The New York Stem Cell Foundation (NYSCF) Research Institute are one step closer to creating a viable cell replacement therapy for multiple sclerosis from a patient's own cells.
In a new study, biophysicists describe– in minute detail- how actin filaments are stabilized at one of their ends to form a basic muscle structure called the sarcomere.
Trillions of bacteria live in each person’s digestive tract, but their role in human health is not well understood. To help shed light on the role of these bacteria, a team of researchers recently tracked fluctuations in the bacterial populations of two research subjects over a full year.
