Doubt cast over air pollution link between childhood leukemia and power lines
Researchers from the UK have called into question a theory suggesting that a previously reported risk of leukemia among children born close to overhead power lines could be caused by an alteration to surrounding air pollution.

Self-reported cognitive difficulties better for patients with tinnitus in clinical trial
Using the medication D-cycloserine in conjunction with a computer-assisted cognitive training program to try to improve the bother of tinnitus (persistent ringing in the ears) and its related cognitive difficulties was no more effective than placebo at relieving the bother of the annoying condition although self-reported cognitive deficits improved, according to a study published online by JAMA Otolaryngology-Head & Neck Surgery.

Why scratching makes you itch more
Turns out your mom was right: scratching an itch only makes it worse. New research from scientists at the Center for the Study of Itch at Washington University School of Medicine in St. Louis reveals that scratching causes the brain to release serotonin, which intensifies the itch sensation.

Hygienic funerals, better protection for health workers offer best chance to stop Ebola
Hygienic funeral practices, case isolation, contact tracing with quarantines, and better protection for health care workers are the keys to stopping the Ebola epidemic that continues to expand in West Africa, researchers said today in a new report in the journal Science. They said broad implementation of aggressive measures they recommend could lead to its control in Liberia, the focal point, by mid-March.

Frailty increases kidney transplant recipients' risk of dying prematurely
Regardless of age, frailty is a strong risk factor for dying prematurely after a kidney transplant. The finding, which comes from a new study published in the American Journal of Transplantation, suggests that patients should be screened for frailty prior to kidney transplantation, and that those who are identified as frail should be closely monitored after the procedure.

Air quality and unconventional oil and gas sites
Research suggesting air pollutants released by unconventional oil and gas production are well over recommended levels in the US is published today in the open access journal Environmental Health. High levels of benzene, hydrogen sulfide and formaldehyde were found. The study is the first to be based on community sampling by people who live near production sites and could be used to supplement official air-quality monitoring programs.

Science casts light on sex in the orchard
Persimmons are among the small club of plants with separate sexes -- individual trees are either male or female. Now scientists at the UC Davis and Kyoto University in Japan have discovered how sex is determined in a species of persimmon, potentially opening up new possibilities in plant breeding.

Rewiring cell metabolism slows colorectal cancer growth
A University of Utah-led study reports that cancers select against a protein complex called the mitochondrial pyruvate carrier, and re-introduction of MPC in colon cancer cells impairs several properties of cancer, including growth. The research, which appears online on Oct. 30 in Molecular Cell, implicates changes in a key step in metabolism -- the way cellular fuel is utilized -- as an important driver of colon cancer that is also likely to be important in many other cancer settings.

Scripps Research Institute scientists capture picture of 'MicroRNA' in action
Biologists at The Scripps Research Institute have described the atomic-level workings of 'microRNA' molecules, which control the expression of genes in all animals and plants. The findings add greatly to the understanding of a fundamental system of regulation in biology, and should accelerate the development of therapies that harness its power.

Smithsonian scientist discovers populations of rare songbird in surprising new habitat
With only 90,000 breeding individuals sparsely distributed across 15 US states, the Swainson's warbler is a species of high conservation concern that, for decades, has left conservationists with little confidence that its populations would ever be fully secure. New research reveals that populations of Swainson's warbler are increasing in a surprising new habitat found mostly on private lands -- pine plantations on nearly 16 million hectares on the coastal plain from eastern Texas to southeastern Virginia.

Mediterranean diet may help protect kidney health
Every one-point increase in a Mediterranean diet score was associated with a 17 percent decreased likelihood of developing chronic kidney disease. Dietary patterns that closely resembled the Mediterranean diet were linked with a 50 percent reduced risk of developing chronic kidney disease and a 42 percent reduced risk of experiencing rapid kidney function decline.

Genetic factors behind surviving or dying from Ebola shown in mouse study
A newly developed mouse model suggests that genetic factors are behind the mild-to-deadly range of responses to the Ebola virus. The frequency of different manifestations of the disease across the lines of these mice are similar in variety and proportion to the spectrum of clinical disease observed in the 2014 West African outbreak. The new mouse model might be useful in testing candidate therapeutics and vaccines for Ebola, and in finding genetic markers for susceptibility and resistance to the disease.

How 'trained immunity' mediates BCG therapy of bladder cancer
Bacillus Calmette-Guerin is a vaccine widely used in low and middle-income countries to protect against childhood tuberculosis. Besides its specific anti-tuberculosis effects, Bacillus Calmette-Guerin can also function as a general immune-booster, and in this capacity is used in the treatment of certain bladder cancers. A study published on Oct. 30 in PLOS Pathogens now reports that autophagy, the removal and degradation of unnecessary or dysfunctional components within cells, plays a central role in mediating the non-specific immune effects of Bacillus Calmette-Guerin.

Emerging disease could wipe out American, European salamanders
A fungal disease from Asia wiped out salamanders in parts of Europe and will likely reach the US through the international wildlife trade in Asian newts sold as pets, say US experts. In an Oct. 31 Science paper, an international team reports the fungus arose in Asia 30 million years ago and is lethal to many European and American newt species. It has not yet been found in North American wild amphibians.

Lou Gehrig's disease study: Renewing brain's aging support cells may help neurons survive
Lou Gehrig's disease, also known as amyotrophic lateral sclerosis, or ALS, attacks muscle-controlling nerve cells -- motor neurons -- in the brain, brainstem and spinal cord. Now, with publication of a study by investigators at the Cedars-Sinai Board of Governors Regenerative Medicine Institute, ALS researchers know the effects of the attack are worsened, at least in part, by the aging and failure of support cells called astrocytes, which normally provide nutrients, housekeeping, structure and other forms of assistance for neurons.

'Nanomotor lithography' answers call for affordable, simpler device manufacturing
What does it take to fabricate electronic and medical devices tinier than a fraction of a human hair? Nanoengineers at the University of California, San Diego recently invented a new method of lithography in which nanoscale robots swim over the surface of light-sensitive material to create complex surface patterns that form the sensors and electronics components on nanoscale devices. Their research was published recently in the journal Nature Communications.

Griffith scientists propose existence and interaction of parallel worlds
Griffith University academics are challenging the foundations of quantum science with a radical new theory on parallel universes. In a paper published in the journal Physical Review X, Professor Howard Wiseman and Dr. Michael Hall from Griffith's Centre for Quantum Dynamics, and Dr. Dirk-Andre Deckert from the University of California, propose that parallel universes really exist, and that they interact. They show that such an interaction could explain everything that is bizarre about quantum mechanics
