In an article published July 17, 2018 by Nature Communications, a highly collaborative team of researchers at the Medical University of South Carolina (MUSC) and Ohio State University report that normal breast cells can prevent successful radiation treatment of breast cancer due to dysregulation between tumor suppressors and oncogenes. Tumor suppressors act like brakes that stop cells from undergoing uncontrolled growth, while oncogenes are the gas pedal. The tumor suppressor gene of interest in this study is PTEN, which is often mutated in human cancer cells.

Montreal, Aug. 1, 2018 - Treatment of latent tuberculosis is set to transform after a pair of studies from the Research-Institute of the McGill University Health Centre (RI-MUHC) revealed that a shorter treatment was safer and more effective in children and adults compared to the current standard. These findings are published today in the New England Journal of Medicine.

Rochester, MN, August 1, 2018 - Sauna bathing is an activity used for the purposes of pleasure, wellness, and relaxation. Emerging evidence suggests that beyond its use for pleasure, sauna bathing may be linked to several health benefits.

DURHAM, N.C. -- For a small, reddish-beaked bird called the zebra finch, sexiness is color-coded. Males have beaks that range from light orange to dark red. But from a female's point of view, a male's colored bill may simply be hot, or not, new findings suggest.

Due to a phenomenon called categorical perception, zebra finches partition the range of hues from red to orange into two discrete categories, much like humans do, researchers report August 1 in the journal Nature.

Washington, DC--Blue diamonds--like the world-famous Hope Diamond at the National Museum of Natural History--formed up to four times deeper in the Earth's mantle than most other diamonds, according to new work published on the cover of Nature.

"These so-called type IIb diamonds are tremendously valuable, making them hard to get access to for scientific research purposes," explained lead author Evan Smith of the Gemological Institute of America, adding, "and it is very rare to find one that contains inclusions, which are tiny mineral crystals trapped inside the diamond."

Soil is full of life, essential for nutrient cycling and carbon storage. To better understand how it functions, an international research team led by EMBL and the University of Tartu (Estonia) conducted the first global study of bacteria and fungi in soil. Their results show that bacteria and fungi are in constant competition for nutrients and produce an arsenal of antibiotics to gain an advantage over one another. The study can also help predict the impact of climate change on soil, and help us make better use of natural soil components in agriculture.

Keratinocyte skin cells are common targets of the beta subtype of human papilloma virus. This usually harmless infection causes skin disease in people with rare gene mutations.[/caption]

You're probably infected with one or more subtypes of the human papilloma virus--and, as alarming as that may sound, odds are you will never show any symptoms. The beta subtype of the virus, ß-HPV, is widespread in the general population and the least pathogenic; in fact, most carriers don't even know that they have it.

ALBUQUERQUE, N.M. -- Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve the detection sensitivity for chemicals in explosives or drugs.

"Our supercrystals have more sensing capability than regular spectroscopy instruments currently in use, just like a dog's nose has more sensing capabilities than a human's," said lead Sandia researcher Hongyou Fan.

Eating high fibre foods may reduce the effects of stress on our gut and behaviour, according to new research published in The Journal of Physiology.

Stress is a significant health concern and can cause major changes in the gut and in the brain, which can cause changes in behaviour. In recent years there has been growing interest in the link between gut bacteria and stress-related disorders including anxiety, depression and irritable bowel syndrome.

CLEVELAND--Researchers at Case Western Reserve University are using wearable sensor technology to develop an automatic alert system to help people quit smoking.

The smart-phone app, initially limited to android-based operating systems, automatically texts 20- to 120-second video messages to smokers when sensors detect specific arm and body motions associated with smoking.

There is no shortage of products or programs--from nicotine gum to hypnosis--to help people stop smoking. More recently, wearable technology has gained popularity in the fight against addiction.
