Scientists have identified 23 new genetic variants that indicate a person's risk of prostate cancer, enabling them to explain up to a third of inherited risk. Screening for prostate cancer has seen huge advances, with scientists recently identifying 23 new genetic variants associated with risk of the disease.

Tiny marine algae can evolve fast enough to cope with climate change in a sign that some ocean life may be more resilient than thought to rising temperatures and acidification, a study showed. Evolution is usually omitted in scientific projections of how global warming will affect the planet in coming decades because genetic changes happen too slowly to help larger creatures such as cod, tuna or whales.

RESEARCH into the genetic causes of epilepsy has received a cash boost after a A 50,000 donation from the Buckinghamshire Freemasons. The group gave the Chalfont St Peter-based Epilepsy Society the cash windfall in order for the charity to fund work into finding a molecular cause to the condition.

One of the hot research techniques these days, "optogenetics," uses gene therapy to deliver light-sensitive proteins to specific cells. Then researchers use light to control the cells.
Using a zebrafish model of a human genetic disease called neurofibromatosis , a team from the Perelman School of Medicine at the University of Pennsylvania has found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches. They published their results this month in Cell Reports .
Through the power of technology, humans are set to upgrade ourselves and surmount evolution. Ultimately, we can become entirely new beings that set the stage for a post-human future.
New molecular genetics approaches have been developed over the past several years to study brain serotonin neuron development and the roles of 5-HT neurons in behavior and physiology. These approaches were enabled by manipulation of the gene encoding the Pet-1 ETS transcription factor whose expression in the brain is restricted to developing and adult 5-HT neurons.
Researchers at the RIKEN Center for Developmental Biology in Japan surgically transplanted a sheet of retinal pigment cells into the eye of a 70-year old woman on Friday. The cells are the first induced pluripotent stem cells, or iPS cells, given to a human patient.
Sickle cell disease had been considered a pediatric ailment since people with it generally didn't live to adulthood. Pediatricians report that 95% now live to their 20th birthday.
A small protein named GILZ appears to protect against the bone loss that often accompanies arthritis and its treatment, researchers report. Arthritis as well as aging prompt the body to make more fat than bone, and the researchers have previously shown GILZ can restore a more youthful, healthy mix.
Physicians envision a future in which genomic data from patients is heavily used to manage care, but experts have questioned the accuracy and reliability of these analyses. Now, a study by 150 researchers in 12 countries finds real strength and agreement across RNA genomic sequencing techniques and laboratories -- as well as ways to improve what little variability exists to set a new high standard.
Scientists have created an advanced model aimed at exploring the role of neutral evolution in the biogeographic distribution of ocean microbes. Over the past sev eral decades, ecol o gists have come to under stand that both natural selec tion and neu tral evolution -- that vari a tion within and between species is caused by genetic drift and random mutations -- play a role in the bio geo graphic pat terns of ocean microbes.
Geneticist Wendy Chung describes what it's like to chip away at the mysteries of autism, and the excitement of uncovering tiny but critical clues. Wendy Chung is the director of clinical research at the Simons Foundation Autism Research Initiative , which does both basic and applied science to serve people affected by autism spectrum disorders.
Endometriosis often takes a long time to be diagnosed and affects all areas of a women's life, a study has found. Research led by Monash University's Kate Young published in the Journal of Family Planning and Reproductive Health Care found that endometriosis affects women 's sex lives, personal relationships , work life, and emotional wellbeing.
No Silicon Valley company better embodies the promise and the pitfalls of working in health care than DNA testing firm 23andMe. Launched in 2006 to a flurry of media coverage, the Mountain View, California-based company seemed to have every strategic advantage: millions in startup cash, celebrity endorsements, and a chief executive married to one of the co-founders of Google.
A scientific team led by UCSF microbiome expert Michael Fischbach, PhD, identified more than 3,000 clusters of bacterial genes at different body sites that contain the blueprints for cellular factories that make drug-like molecules. One of the molecules discovered based on gene-cluster identification, an antibiotic the researchers named lactocillin, is assembled by enzymes encoded by genes within the circular DNA plasmid of the bacterium, Lactobacillus gasseri, a common resident of the vagina.
