Using a type of human stem cell, researchers say they have created a 3-D complement of human retinal tissue in the laboratory, which includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.
Researchers are a step closer to establishing the link between a protein with a split personality and type 1 diabetes. New research shows how the protein GAD65 changes its shape when it turns itself on and off. This characteristic may also link it to type 1 diabetes.
Researchers have discovered that oxytocin– a hormone associated with maternal nurturing, social attachments, childbirth and sex– is indispensable for healthy muscle maintenance and repair, and that in mice it declines with age.
A daily supplement of an extract found in tomatoes may improve the function of blood vessels in patients with cardiovascular disease, according to new research.
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique — and important — properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide that enables it to target tumor cells. What’s more, the shell is etchable so those nanoparticles that don’t hit their target can be broken down and eliminated.
Researchers have found that hormone replacement therapy in young women with primary ovarian insufficiency (POI) led to increases in their bone mineral density, restoring levels to normal. The findings provide important treatment information for women with POI and their physicians.
Twelve years ago, researchers found that a protein called Set2 plays a role in how yeast genes are expressed– specifically how DNA gets transcribed into messenger RNA. Now, it has been discovered that Set2 is also a major player in DNA repair, a complicated and crucial process that can lead to the development of cancer cells.
New genomic research revealed that two common gene variants that lead to longer telomeres, the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging, also significantly increase the risk of developing the deadly brain cancers known as gliomas.
Vitamin D has been shown to play an important role in liver function. Now, a new study in Western Europeans shows that vitamin D lowers the risk of developing hepatocellular carcinoma (HCC), the main form of liver cancer.
Infants exposed to rodent and pet dander, roach allergens and a wide variety of household bacteria in the first year of life appear less likely to suffer from allergies, wheezing and asthma, according to a new study.
The current state of science on the adverse health effects of marijuana use links the drug to several significant adverse effects including addiction, a new review reports.
Scientists have identified problems in a connection between brain structures that may predispose individuals to hearing the “voices” that are a common symptom of schizophrenia. Researchers linked the problem to a gene deletion.
Cytomegalovirus, or CMV, is perhaps one of the biggest pathogens you’ve never heard of—big, both proportionately and epidemiologically. If you’re healthy, it’s harmless, but if you have an impaired immune system, the virus can assert itself with a vengeance. Now, researchers have discovered a menu of tactical secrets CMV employs.
The calorie-burning triggered by cold temperatures can be achieved biochemically– without the chill– raising hopes for a weight-loss strategy focused on the immune system rather than the brain, according to a new study.
Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs. Now, researchers have identified a critical weakness that actually exploits one of these cells’ apparent strengths—their ability to move and invade tissues.
A large new analysis of DNA from thousands of patients has uncovered several underlying gene networks with potentially important roles in autism. These networks may offer attractive targets for developing new autism drugs or repurposing existing drugs that act on components of the networks.
Improved diagnosis and management of one of the most common cancers in men- prostate cancer- could result from research, which has discovered that seminal fluid (semen) contains biomarkers for the disease.
You are what you eat, but researchers are beginning to realize that what and when you eat is controlled by a myriad of underlying biological triggers acting in concert.
A new study shows how exposure to air pollution early in life produces harmful changes in the brains of mice, including an enlargement of part of the brain that is seen in humans who have autism and schizophrenia.
The popular “Paleo diet,” oft described as an ancient diet dominated by grasses and modeled after diets from the Paleolithic period, may not quell hunger better than the modern “McDonald’s” diet.
Surgery and radiation for a glioblastoma have only limited effectiveness because the tumor is particularly aggressive, infiltrating brain tissue surrounding the primary tumor. Scientists have developed a technique designed to open the blood-brain barrier at targeted locations just far enough to allow the passage of drug-bearing nanoparticles.
By studying laboratory mice, scientists have succeeded in plotting the labyrinthine paths of some of the largest nerve cells in the mammalian brain: cholinergic neurons, the first cells to degenerate in people with Alzheimer’s disease.
Scientists have discovered that bacteria can reshape their DNA to survive dehydration. The research shows that bacterial DNA can change from the regular double helix to the more compact A-DNA form, when faced with hostile conditions such as dehydration.
While it was known that a specific birch pollen protein causes the immune system to overreact, the exact reason why many people are allergic to birch pollen had not yet been fully clarified. Now, scientists at the Vetmeduni Vienna have discovered what makes the protein an allergen.
