Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
Depression can hit young fathers hard- with symptoms increasing dramatically during some of the...
The first human volunteer will receive red blood cells cultured in the laboratory within the...
A mumps outbreak in central Ohio has grown to more than 200 confirmed cases, public health officials said. A total of 212 cases of the contagious viral illness, with 132 of those linked to Ohio State University, have been reported.
A team of scientists published details of how a class of drugs called “HDACis” drive muscle-cell regeneration in the early stages of dystrophic muscles, but fail to work in late stages. The findings are key to furthering clinical development of HDACis for Duchenne muscular dystrophy (DMD), an incurable muscle-wasting disease.
Scientists at the University of Basel report first ever successful nose reconstruction surgery using cartilage grown in the laboratory. Cartilage cells were extracted from the patient’s nasal septum, multiplied and expanded onto a collagen membrane. The so-called engineered cartilage was then shaped according to the defect and implanted.
Synthetic collagen invented at Rice University may help wounds heal by directing the natural clotting of blood. The material, KOD, mimics natural collagen, a fibrous protein that binds cells together into organs and tissues. It could improve upon commercial sponges or therapies based on naturally derived porcine or bovine-derived collagen now used to aid healing during or after surgery.
Scientists are attempting to build a human heart with a 3-D printer. Ultimately, the goal is to create a new heart for a patient with their own cells that could be transplanted. It is an ambitious project to first, make a heart and then get it to work in a patient, and it could be years — perhaps decades — before a 3-D printed heart would ever be put in a person.
The more cups of coffee a person drank, the lower the risk for developing hepatocellular carcinoma (HCC), the most common type of liver cancer, according to new research.
When NASA sends an identical twin to the International Space Station next year, a Colorado State University researcher will be among just a few hand-picked scientists studying him and his brother to measure impacts of space travel on the human body.
An antimicrobial agent found in common household soaps, shampoos, and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection.
In a north London hospital, scientists are growing noses, ears and blood vessels in a bold attempt to make body parts in the laboratory. It's far from the only lab in the world that is pursuing the futuristic idea of growing organs for transplant. But the London work was showcased Tuesday as Mayor Boris Johnson announced a plan to attract more labs to do cutting-edge health and science research in the area.
A U.S. jury ordered Japanese drugmaker Takeda Pharmaceutical Co. and its U.S. counterpart, Eli Lilly and Co., to pay $9 billion in punitive damages over a diabetes medicine linked to cancer. The drug companies said Tuesday they will "vigorously challenge" the decision. The U.S District Court in western Louisiana ordered a $6 billion penalty for Takeda and $3 billion for its business partner and co-defendant Eli Lilly.
Researchers have devised a way to quickly bring to the clinic the technique of using blood samples to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient’s body and responses to treatment.
Scientists may have discovered a new way to treat a type of childhood brain tumor that has proved incurable up until now, according to a recent study.
Researchers have generated a 3-D model of the human malaria parasite genome at three different stages in the parasite’s life cycle— the first time such 3-D architecture has been generated during the progression of the life cycle of a parasite.
A research team was able to demonstrate for the first time that caffeine has a positive effect on tau deposits in Alzheimer's disease. Tau deposits, along with beta-amyloid plaques, are among the characteristic features of Alzheimer's disease.
In their pursuit of understanding how pain works at the molecular level, a research team has found a new function for MicroRNAs, short stretches of genetic material that signal genes to turn on or off.
Chances are you've heard of mapping genes to diagnose rare diseases, predict your risk of cancer and tell your ancestry. But to uncover food poisonings? The nation's disease detectives are beginning a program to try to outsmart outbreaks by routinely decoding the DNA of potentially deadly bacteria and viruses.
What began 20 years ago as an innovation to improve paper industry processes and dairy forage digestibility may now open the door to a much more energy- and cost-efficient way to convert biomass into fuel. New research focuses on enhancing poplar trees so they can break down easier and thus improving their viability as a biofuel.
Scleroderma is a rare and often fatal disease, causing the thickening of tissue, which currently lacks a cure and any effective treatments. A group of researchers, including a Michigan State University professor, is looking to change that. Neubig, along with several of his colleagues from the University of Michigan, have identified the core signaling pathway that activates the disease and the chemical compounds that can turn it off.
University of Utah neuroscientists report that when a region of the brain called the lateral habenula is chronically inactivated in rats, they repeatedly drink to excess and are less able to learn from the experience. The study has implications for understanding behaviors that drive alcohol addiction.
Be sure to pick up a watermelon—or two—at your local grocery store. It could save your life. A new study found that watermelon could significantly reduce blood pressure in overweight individuals both at rest and while under stress.
Improved thinking. Decreased appetite. Lowered blood pressure. The potential health benefits of dark chocolate keep piling up, and scientists are now homing in on what ingredients in chocolate might help prevent obesity, as well as type-2 diabetes. They found that one particular type of antioxidant in cocoa prevented laboratory mice from gaining excess weight and lowered their blood sugar levels.
The U.S. Food and Drug Administration has approved the first tablet for gradually reducing hay fever allergy symptoms, an alternative to uncomfortable allergy-desensitizing shots. Oralair, a tablet that dissolves quickly under the tongue, is approved for patients aged 10 through 65. It's to be...
Researchers from the University of California, San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences, in collaboration with materials scientists, engineers and neurobiologists, have discovered a new mechanism for using light to activate drug-delivering nanoparticles and other targeted therapeutic substances inside the body.
New research from Wake Forest Baptist Medical Center suggests that physicians are ordering vitamin D deficiency screening tests for preventive care purposes rather than after patients develop conditions caused by decreased bone density.
Clinical investigators at the Children’s Hospital of Eastern Ontario (CHEO) have developed a new screening tool to help diagnose obstructive sleep apnea in children. Evidence suggests that adults with a large neck circumference are more likely to develop obstructive sleep apnea (OSA), especially males. As neck circumference varies by age and sex, there have been no reference ranges to diagnose pediatric OSA up until now.
