Cotton Candy Machine Could Lead to the Creation of Artificial Organs

February 10, 2016 | by Bevin Fletcher, Associate Editor | Comments

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.


Sleep Apnea Takes a Toll on Brain Function

February 12, 2016 10:43 am | by UCLA | Comments

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.


WHO: Possible Zika Vaccines Months Away From Broad Trials

February 12, 2016 10:38 am | by The Associated Press | Comments

The World Health Organization says possible Zika vaccines are at least 18 months away from large-scale trials.


Gene Signature Could Lead To A New Way Of Diagnosing Lyme

February 12, 2016 10:35 am | by UCSF | Comments

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.


E-cigarettes May Change Immune Response in Lungs

February 12, 2016 10:27 am | by UNC | Comments

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.


Pinpointing Loneliness in the Brain

February 12, 2016 10:20 am | by Anne Trafton, MIT News Office | Comments

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.

February 12, 2016 9:46 am | by Malcolm Ritter, AP Science Writer | Comments

A new study says a person's risk of becoming depressed or hooked on smoking may be influenced by DNA inherited from Neanderthals.


New Device Could Enable Brain Control of Exoskeletons

February 12, 2016 9:01 am | by Bevin Fletcher, Associate Editor | Comments

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.

February 11, 2016 12:07 pm | by Joshua Goodman, Associated Press | Comments

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.


Scientists Find Leukemia's Surroundings Key to its Growth

February 11, 2016 12:02 pm | by University of Texas at Austin | Comments

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.


Chemical Cages: New Technique Advances Synthetic Biology

February 11, 2016 11:32 am | by Arizona State University | Comments

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.

Dementia Risk Varies Significantly Among Racial And Ethnic Groups, Study Finds

February 11, 2016 10:30 am | by UCSF | Comments

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.


Sneezes, Frame by Frame

February 11, 2016 10:22 am | by Jennifer Chu, MIT News Office | Comments

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.

February 11, 2016 10:14 am | by The Associated Press | Comments

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.


Poor Fitness May Affect Brain Volume Decades Later

February 11, 2016 9:44 am | by Bevin Fletcher, Associate Editor | Comments

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.
