Periodic bursts of genetic mutations drive prostate cancer
Cancer is typically thought to develop after genes gradually mutate over time, finally overwhelming the ability of a cell to control growth. But a new closer look at genomes in prostate cancer by an international team of researchers reveals that, in fact, genetic mutations occur in abrupt, periodic bursts, causing complex, large scale reshuffling of DNA driving the development of prostate cancer.

Quit smoking? Vitamin E may give extra boost to heart health
Taking a specific form of a vitamin E supplement can accelerate the health benefits that occur when people quit smoking, new research suggests.

New research from Wake Forest Baptist Medical Center finds that CVD risk factors may be overlooked during survivorship care.

Tumors with ALK rearrangements can harbor more mutations
The identification of potentially targetable kinase mutations has been an exciting advancement in lung cancer treatment. Although the mutations driving many lung carcinomas remain unknown, approximately 50 percent of lung adenocarcinoma cases harbor KRAS mutation, EGFR mutation, or ALK translocation, and an additional 5 percent or so have been shown to have mutations involving BRAF, PIK3CA, HER2, MET, MEK1, NRAS, and AKT. In the vast majority, these driver mutations are mutually exclusive.

New fatigue model leads to more durable ships
Heikki Remes, a researcher at the Aalto University in Finland, has developed a model making it possible to determine how fatigue sets in with various welded steel materials. The model allows for the development of lighter structures, and as a consequence, more energy-efficient ships.

Atherosclerosis -- sometimes called

Smartphone way to lose weight
Forget fad diets and hypnotherapy; your smartphone could be a key tool to losing those post-Easter egg pounds, according to scientists at the University of Leeds, UK.

Coelacanth genome surfaces
An international team of researchers has decoded the genome of the African coelacanth. The species was once thought to be extinct, but a living coelacanth was discovered off the African coast in 1938. Coelacanths today closely resemble the fossilized skeletons of their more than 300-million-year-old ancestors. Its genome confirms what many researchers had long suspected: genes in coelacanths are evolving more slowly than in other organisms.

New research examines connection between inflammatory stimulus and Parkinson's disease
Parkinson's disease is a progressive degenerative disease affecting a person's ability to coordinate and control their muscle movement. What starts out as a tremor in a finger will eventually lead to difficulty in writing and speaking, and ultimately the inability to walk without assistance.

Tiny octopus-like microorganisms named after science fiction monsters: UBC research
University of British Columbia researchers have discovered two new symbionts living in the gut of termites, and taken the unusual step of naming them after fictional monsters created by American horror author HP Lovecraft.

Reviving a foe of cancer
p53 is a vitally important tumor suppressor whose function is disrupted in one way or another in various cancer types. In the recent issue of Cancer Cell, a research team, led by Xin Lu, Ph.D., Ludwig director and member at the University of Oxford, describes how p53 is silenced in advanced melanomas by a protein named iASPP, and applies that information to restore p53 function in such cells.

Intensity modulated radiotherapy reduces side effects in patients with early breast cancer
Intensity modulated radiotherapy gives better results than standard radiotherapy in patients with early breast cancer, according to results from a randomized trial presented on Sunday to the 2nd Forum of the European Society for Radiotherapy and Oncology. IMRT is an advanced, high-precision form of radiotherapy that can deliver an even dose of radiation, thus reducing the cosmetic problems that can often occur after breast radiotherapy.

Although previous research has linked alcohol consumption to an increased risk of developing breast cancer, a new study has found that drinking before and after diagnosis does not impact survival from the disease.

Teens' brains are more sensitive to rewarding feedback from peers
Teenagers are risk-takers -- they're more likely than children or adults to experiment with illicit substances, have unprotected sex, and drive recklessly. But research shows that teenagers have the knowledge and ability to make competent decisions about risk. So what explains their risky behavior? In a new report, psychological scientist Laurence Steinberg and colleagues argue that this risky behavior may reflect the unique effect of peer influence on the still-developing teenage brain.

Vanderbilt study finds lack of exercise not a factor in health disparities
Health disparities between white and black adults in the South are not connected to a lack of exercise but more likely related to other factors such as access to health care, socioeconomic status and perhaps genetics, according to a Vanderbilt study published in the journal PLOS ONE.

How would you like your assistant -- Human or Robotic?
In a Georgia Tech study, more than half of healthcare providers interviewed said that if they were offered an assistant, they preferred it to be a robotic helper rather than a human. However, they don't want robots to help with everything. They were very particular about what they wanted a robot to do, and not do.

Endangered African language explored
Children growing up in the Rufiji region along the coast of Tanzania are learning Swahili as their first language. Consequently, their parents are expected to be the last generation to be fluent in the minority language Ndengeleko. A new doctoral thesis in African languages from the University of Gothenburg is the first, and maybe last, attempt ever to explore Ndengeleko grammatically.

Taken under the 'wing' of the small magellanic cloud
The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors. In fact, it was so bright that many navigators used this object to make their way across the oceans. A new composite image from three NASA telescopes -- Chandra, Hubble, and Spitzer -- shows this galaxy like Ferdinand Magellan, who lends his name to the SMC, could never have imagined.

Dedicated cleaning staff shown to reduce C. difficile contamination in hospital rooms
New research finds that a dedicated daily cleaning crew who adequately clean and disinfect rooms contaminated by C. difficile using a standardized process can be more effective than other disinfection interventions. The study is published in the May issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, in a special topic issue focused on the role of the environment in infection prevention.

Insights into deadly coral bleaching could help preserve reefs
Coral reefs are stressed because of climate change. Researchers from Northwestern University and The Field Museum of Natural History have discovered corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons. No one else has shown this before. Using optical technology designed for early cancer detection, the researchers discovered that reef-building corals scatter light in different ways to the symbiotic algae that feed the corals.
