Gene mutation causes low sensitivity to pain
Gene mutation causes low sensitivity to pain
A UCL-led research team has identified a rare mutation that causes one family to have unusually low sensitivity to pain. The researchers hope the findings, published today in Brain , could be used to identify new treatments for chronic pain. They studied an Italian family, the Marsilis, which includes six people who have a distinctive pain response that has not been identified in any other people.

Cells remember infections decades later
A perplexing question in immunology has been, how do immune cells remember an infection or a vaccination so that they can spring into action decades later? Research led by scientists at the UCalifornia, Berkeley, in collaboration with investigators at Emory University, has found an answer: A small pool of the same immune cells that responded to the original invasion remain alive for years, developing unique features that keep them primed and waiting for the same microbe to re-invade the body.

27% of California adolescents are gender nonconforming, study finds
It is the first representative survey of the state's youth population to measure gender expression Rachel Dowd A new UCLA study finds that 27 percent, or 796,000, of California's youth, ages 12 to 17, report they are viewed by others as gender nonconforming at school. The study also assessed differences in mental health among gender nonconforming youth and gender conforming youth in the state, and found no significant difference in the rates of lifetime suicidal thoughts and suicide attempts between gender nonconforming youth and their gender conforming peers.

Cellular Self-Digestion Process Triggers Autoimmune Disease
Autophagy refers to a fundamental recycling process of cells that occurs in yeast, fungi, plants, as well as animals and humans. This process allows cells to degrade their own components and thus activate energy resources to be able to adapt to nutritional needs. In addition, autophagy plays a central role in steering an organism's immune response.

Reporting a few cases of negative side effects is alarmist and damaging
A story aired on the ABC that reported on issues concerning long-acting contraceptives was unbalanced and alarmist writes Associate Professor Kirsten Black. Last night ABC's 7.30 featured a report on long-acting reversible contraception (LARC) that was unbalanced and alarmist. This could have a long-lasting detrimental impact on women's reproductive health in Australia.

Pediatric cancer providers give medical marijuana a cautious thumbs-up
New research by Yale Cancer Center (YCC) researchers shows a majority of pediatric cancer providers endorse the potential use of medical marijuana for children with advanced cancer, although providers who are legally eligible to certify its use are more cautious than those who aren't. The findings also show clinicians would prefer to see much stronger clinical evidence that marijuana treatments can help in relieving symptoms, such as nausea and pain.

Ultra-thin tissue samples could help to understand and treat heart disease
Ultra-thin tissue samples could help to understand and treat heart disease
A new method for preparing ultra-thin slices of heart tissue in the lab could help scientists to study how cells behave inside a beating heart. The heart is made up of millions of individual muscle cells called cardiomyocytes that are kept in place by a criss-crossing network of collagen fibres. These cells work together, contracting in sync to create a strong and regular heartbeat.

How privacy policies affect genetic testing
How privacy policies affect genetic testing
Different types of privacy laws in U.S. states produce markedly different effects on the willingness of patients to have genetic testing done, according to a new study co-authored by an MIT professor. As the research shows, policies that focus on the privacy risks of genetic testing, and ask for patient consent to those risks, lead to a reduction in tests performed.

Scientists successfully demonstrate a new way to help nerve regeneration in spinal cord injury
Scientists successfully demonstrate a new way to help nerve regeneration in spinal cord injury
A new way of triggering nerve regeneration to help repair spinal cord injury and in the longer-term potentially paralysis has successfully been demonstrated by University of Bristol scientists. The work is published in PLOS ONE today [Monday 11 December]. There is currently no cure for spinal cord injury or treatment to help nerve regeneration so therapies offering intervention are limited.
