As more states legalize medical marijuana, there's one stage in the process nobody wants to talk about: the part where people still have to break the law.
A nurse who protested being kept in a tent in New Jersey over the weekend despite lacking symptoms after caring for Ebola patients in West Africa was to be released Monday as scientists and federal officials clashed with state officials over quarantine policies.
Researchers have now discovered that FLRT proteins on the surface of progenitor cells can induce repellent and attractant signals depending on its binding partner.
A hormone seen as a popular target to develop weight loss drugs works by directly targeting the brain and triggering previously unknown activity in the nervous system, obesity researchers have found.
Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists.
A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.
Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists have now uncovered a new protein that participates in active HIV replication.
Researchers have uncovered the genes that are normally activated during recovery from bacterial infection. The finding could lead to ways to jumpstart this recovery process and possibly fend off autoimmune diseases and chronic inflammatory disorders.
The World Health Organization says millions of doses of two experimental Ebola vaccines could be ready for use in 2015 and five more experimental vaccines will start being tested in March.
Officials tried to tamp down New Yorkers' fears Friday after a doctor was diagnosed with Ebola in a city where millions of people squeeze into crowded subways, buses and elevators every day.
Physicians will tell you: They are not winning the war on ovarian cancer. But researchers have combined medicine and advanced nanotechnological engineering to create a smarter, more targeted therapy that could overcome the most lethal gynecologic cancer.
Using an innovative exome sequencing strategy, a team of international scientists has shown that TUBA4A, the gene encoding the Tubulin Alpha 4A protein, is associated with familial amyotrophic lateral sclerosis (ALS).
Stem cell therapies are being hailed as a potential cure for many major health conditions, but there is much still to learn about the highly complex environments needed to optimize these therapies, according to new research.
Researchers have identified an unusual process by which the body can sense the presence of pathogenic bacteria and destroy them. Rather than detect the microbes directly, individual cells monitor how the bacteria interfere with the functioning of energy-producing cellular structures called mitochondria.
Researchers now developed a new way to model the effects of these genetic mutations in mice. The approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.
Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, researchers working with mice report they have devised a way to detect and monitor in real time infections with a class of dangerous Gram-negative bacteria.
All travelers who come into the U.S. from three Ebola-stricken West African nations will now be monitored for three weeks, the latest step by federal officials to keep the disease from spreading into the country.
The Bertarelli Program in Translational Neuroscience and Neuroengineering, a collaborative program between Harvard Medical School and the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, has announced a new set of grants worth $3.6 million for five research projects.
Children with autism spectrum disorder (ASD) were more likely to have been exposed to higher levels of certain air toxics during their mothers’ pregnancies and the first two years of life compared to children without the condition, according to a new study.
Before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists are reporting that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.
Drawing blood and testing it is standard practice for many medical diagnostics. As a less painful alternative, scientists are developing skin patches that could one day replace the syringe.
Researchers have pinpointed a set of intriguing characteristics in a previously unknown subpopulation of melanoma cancer cells in blood vessels of tumors.
Researchers are facing increasing demands from colleagues, peers and publishers for process documentation including adequate controls, and for extensive documentation of experimental parameters. Without such consideration, there would be little chance to repeat, or even validate, findings.
A top Red Cross official says he is confident the Ebola epidemic can be contained within four to six months. The Ebola outbreak has killed more than 4,500 people since it emerged 10 months ago, with Liberia, Guinea and Sierra Leone the worst-affected countries.
