In very rare cases, fungal infections can spread below the skin’s surface and onto the lymph nodes, bones, digestive tract or even the brain. Researchers have now discovered a genetic deficiency that allows the fungus to spread in this way, a condition called deep dermatophytosis.
Human breast milk is sold for babies on several online sites for a few dollars an ounce, but a new study says buyer beware: Testing showed it can contain potentially dangerous bacteria including salmonella.
Argentine farmworker Fabian Tomasi was never trained to handle pesticides. His job was to keep the crop-dusters flying by filling their tanks as quickly as possible, although it often meant getting drenched in poison. Now, at 47, he's a living skeleton, so weak he can hardly leave his house in Entre Rios province.
Depression is twice as likely in migraine sufferers, say researchers. Both depression and suicidal ideation are much higher among individuals with migraine, a new study found.
A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by a team of international scientists.
New research indicates that brain scans show signs of autism that could eventually support behavior-based diagnosis of autism and effective early intervention therapies.
A colorful wheel developed bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
Researchers have connected very rare and precise duplications and deletions in the human genome to their complex disease consequences by duplicating them in zebrafish.
When we sleep, our brains get rid of gunk that builds up while we're awake, suggests a study that may provide new clues to treat Alzheimer's disease and other disorders.
Determining whether a bacterium is harmful typically requires growing cultures from samples of saliva or blood— a time-intensive laboratory procedure. Now, researchers have developed a microfluidic device that could speed the monitoring of bacterial infections associated with cystic fibrosis and other diseases.
The formation of long-term memory is dependent on protein synthesis at a specific location and time in brain tissues. A research team recently developed a new imaging technique to pinpoint exactly where and when cells produce new proteins.
Examining 12 major types of cancer, scientists have identified 127 repeatedly mutated genes that appear to drive the development and progression of a range of tumors in the body.
Scientists have developed new drugs that— at least in a laboratory dish— appear to halt the brain-destroying impact of a genetic mutation at work in some forms of two incurable diseases, ALS and dementia.
The question of how the complex networks of nerves and blood vessels develop in tandem has remained largely unanswered. Although recent consensus holds that nerves form first and direct blood vessels to follow their lead, new research has uncovered an alternate process in a more complex tissue: the base, or pad, of mouse whiskers.
A team of scientists has discovered that a gene mutation found in some bladder cancers is indicative of low-risk tumors that are unlikely to recur or progress after surgery.
In two parallel projects, researchers have created new genomes inside the bacterium E. coli in ways that test the limits of genetic reprogramming and open new possibilities for increasing flexibility, productivity and safety in biotechnology.
What many commuters choking on smog have long suspected has finally been scientifically validated: air pollution causes lung cancer. The International Agency for Research on Cancer declared today that air pollution is a carcinogen.
Living standards have risen significantly in the developed world over the past 50 years, so why aren’t we happier than our grandparents? A new study argues that the psychological benefits from income rises are wiped out by much smaller income losses.
Researchers have created a peptide, linked to a light-responsive dye, capable of switching "on" death pathways and altering critical interactions in B-cell lymphoma cancer cells.
New research shows that chronic itching, which can occur in many medical conditions, is different from the fleeting urge to scratch a mosquito bite because because chronic itching appears to incorporate more than just the nerve cells that normally transmit itch signals.
Scientists have long believed that the neurons that are responsible for relaying touch signals to the central nervous system followed a linear path to the brain with a "labeled-lines" structure. But new research on mouse whiskers reveals that the sensory system's wiring diagram doesn't have a set pattern.
Spraying a plant hormone on broccoli— already one of the planet’s most nutritious foods— boosts its cancer-fighting potential, and researchers say they have new insights on how that works.
For the first time, neuroscientists have observed the neural activity that appears to produce the disordered thinking that causes delusions or hallucinations in patients with schizophrenia.
Researchers have found "America’s favorite cookie,” the Oreo, is just as addictive as cocaine– at least for lab rats. And just like most humans, rats go for the middle first.
