An unlikely tool is behind a new technique that could someday lead to the creation of life-sized artificial livers, kidneys and other essential organs: a cotton candy machine.
Imagine that before performing surgery, doctors could consult software that would determine the...

According to new research people with sleep apnea show significant changes in the levels of two important brain chemicals, which could be a reason that many have symptoms that impact their day-to-day lives.
The World Health Organization says possible Zika vaccines are at least 18 months away from large-scale trials.
Researchers may have found a new way to diagnose Lyme disease, based on a distinctive gene “signature” they discovered in white blood cells of patients infected with the tick-borne bacteria.
Smoking cigarettes dramatically increases a person’s risk for a host of diseases, and there’s an assumption that electronic cigarettes, or e-cigarettes, are not harmful because users do not inhale smoke full of known carcinogens. New findings suggest the story is not that simple.
Neuroscientists have identified a brain region that represents feelings of loneliness. This cluster of cells, located near the back of the brain in an area called the dorsal raphe nucleus (DRN), is necessary for generating the increased sociability that normally occurs after a period of social isolation, the researchers found in a study of mice.
A new study says a person's risk of becoming depressed or hooked on smoking may be influenced by DNA inherited from Neanderthals.
The device that may someday give people with spinal cord injuries the ability to walk just by thinking, is the size of a matchstick and can be implanted into a blood vessel in the brain without the need for invasive surgery.
Brazil has signed an agreement with the University of Texas Medical Branch to develop a vaccine against the Zika virus, adding the goal is for the vaccine to be ready for clinical testing within 12 months.
Researchers have discovered that a type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous.
Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules--the enzymes. In a new study, scientists presents clever means of localizing and confining enzymes and the substrate molecules they bind with, speeding up reactions essential for life processes.
In the largest and longest study thus far of ethnic disparities in dementia risk, researchers compared six ethnic and racial groups within the same geographic population and found significant variation in dementia incidence among them.
New high-speed videos captured by researchers show that as a person sneezes, they launch a sheet of fluid that balloons, then breaks apart in long filaments that destabilize, and finally disperses as a spray of droplets, similar to paint that is flung through the air.
The secretary-general of the Swedish panel that awards the Nobel medicine prize has resigned because of an investigation into disputed stem-cell scientist Paolo Macchiarini.
More evidence for the benefits of physical fitness comes to light in a new Neurology study that found an association between lack of exercise in mid-life and smaller brain size 20 years later.
