Your nose is not the only organ in your body that can sense cigarette smoke wafting through the air. Scientists have shown that your lungs have odor receptors as well.
People with severe mental illness such as schizophrenia or bipolar disorder have a higher risk for substance use, especially cigarette smoking, and protective factors usually associated with lower rates of substance use do not exist in severe mental illness, according to a new study.
Researchers have found that dysfunction in a single gene in mice causes fasting hyperglycemia, one of the major symptoms of type 2 diabetes.
New research results suggest a link between the increasing number of people who have developed allergic asthma in the West and a lack of fruits and vegetables in Western diets.
Researchers have found a way to change alcohol drinking behavior in rodents, using the emerging technique of optogenetics, which uses light to stimulate neurons.
Researchers have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms of cancer.
In a finding that directly contradicts the standard biological model of animal cell communication, scientists have discovered that typical cells in animals have the ability to transmit and receive biological signals by making physical contact with each other, even at long distance.
Restricting calorie consumption is one of the few proven ways to combat aging and has been shown to prolong lifespan in yeast, worms, flies, monkeys, and, in some studies, humans. Now, researchers have developed a computer algorithm that predicts which genes can be "turned off" to create the same anti-aging effect.
Biologists have discovered an effective strategy that could prevent the human immune system from rejecting the grafts derived from human embryonic stem cells, a major problem now limiting the development of human stem cell therapies.
The Food and Drug Administration approved 27 first-of-a-kind drugs in 2013, down from 39 new medications in 2012, which was a 15-year high.
Doctors may need to treat high blood pressure in women earlier and more aggressively than they do in men, according to scientists.
Cancer investigators have genetically engineered a new mouse that mimics a common form of leukemia in humans. Studying the model could lead to new understanding of the disease, they say.
Having shingles, a viral infection that causes a painful rash, may increase the risk of having a stroke years later, according to new research.
New research has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide– a finding with potential links to the underlying causes of many cancers.
Scientists have revealed an atomic-level view of a genetic defect that causes a form of muscular dystrophy, myotonic dystrophy type 2, and have used this information to design drug candidates with potential to counter those defects.
High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, researchers have found.
A new technique for studying the structure of the RSV virion and the activity of RSV in living cells could help researchers unlock the secrets of the virus, including how it enters cells.
Researchers say vitamin E might slow the progression of mild-to-moderate Alzheimer's disease — the first time any treatment has been shown to alter the course of dementia at that stage.
When youngsters continually struggle to fall asleep at night, new research suggests maybe their body clock doesn't match their bedtime. But that doesn't mean tots should be up at all hours.
A study in The Journal of General Physiology helps explain how nicotine exploits the body's cellular machinery to promote addiction. The findings could lead to new therapies to help people quit smoking. According to the Center for Disease Control and Prevention, tobacco accounts for the greatest number of preventable deaths worldwide by any single agent.
Researchers at The Johns Hopkins University have found that introducing testosterone in select areas of a male canary’s brain can affect its ability to successfully attract and mate with a female through birdsong. They also found that enhancing song activity based on testosterone in one brain area can change the size of a separate brain area that regulates song quality.
New findings suggest the oxytocin receptor, a gene known to influence mother-infant bonding and pair bonding in monogamous species, also plays a special role in the ability to remember faces. This research has important implications for disorders in which social information processing is disrupted, including autism spectrum disorder.
One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 billion years ago, but in a primitive form that later evolved into the RNA and DNA molecules that we have in life today. New research shows one way this chain of events might have started.
A study begun in Mexico with the collaboration of university students analyzed the effect of weekend alcohol consumption on the lipids comprising cell membrane and its genetic material, i.e. DNA. Until now, the damage to the packaging of nuclear material in the early stages of alcohol abuse has never been documented.
A previous study of European Caucasian patients with sporadic amyotrophic lateral sclerosis demonstrated that a polymorphism in the microtubule-associated protein Tau (MAPT) gene was significantly associated with sporadic amyotrophic lateral sclerosis pathogenesis. To examine this in a different population, researchers investigated the association of the MAPT gene with sporadic amyotrophic lateral sclerosis in the Chinese Han population.
