A "brown dwarf" star with the catchy name of  WISE J085510.83-071442.5 appears to be the coldest of its kind.

When people think of stars, they think of hot fusion plasma bubbling and erupting.  WISE J085510.83-071442.5,  7.2 light-years away, making it the fourth closest system to our sun, is instead as frosty as Earth's North Pole.

PHILADELPHIA - Sometimes a full-on assault isn't the best approach when dealing with a powerful enemy. A more effective approach, in the long run, may be to target the support system replenishing the supplies that keep your foe strong and ready for battle. A group of researchers from the Abramson Cancer Center and the Perelman School of Medicine at the University of Pennsylvania is pursuing this strategy by employing a novel DNA vaccine to kill cancer, not by attacking tumor cells, but targeting the blood vessels that keep them alive. The vaccine also indirectly creates an immune response to the tumor itself, amplifying the attack by a phenomenon called epitope spreading. The results of the study were published this month in the Journal of Clinical Investigation.

The Dead Mouse Argument

By whatever choice of words it is often argued that because one thing leads to another, adverse consequences must inevitably follow if the opponent's proposed course of action is taken.

By whatever choice of words, the above purely rhetorical "proof" is a complete load of codswallop.

An ancient form of meditation and exercise could help women who suffer from urinary incontinence, according to a new study from UC San Francisco.

In a study scheduled to be published on April 25, 2014 in Female Pelvic Medicine & Reconstructive Surgery, the official journal of the American Urogynecologic Society, UCSF researchers discovered that a yoga training program, designed to improve pelvic health, can help women gain more control over their urination and avoid accidental urine leakage.

Mental health diagnoses have become common in children raised in developed nations.

Medication is often prescribed to treat the symptoms of these conditions but few population-based studies have examined the use of prescription medication to treat mental health problems among younger as well as older school-aged children (8–10). A new CDC report describes the sociodemographic characteristics of children aged 6–17 years prescribed medication or taking medication during the past 6 months for emotional or behavioral difficulties, and describes parental reports of the perceived benefit of this medication.

A new report in Molecular Systems Biology speculates about how primitive cells learned to synthesize their organic components – the molecules that form RNA, lipids and amino acids. The paper also suggests an order for the sequence of events that led to the origin of life. 

A simulated reconstruction of Earth's earliest ocean in the laboratory revealed the spontaneous occurrence of the chemical reactions used by modern cells to synthesize many of the crucial organic molecules of metabolism. Previously, it was assumed that these reactions were carried out in modern cells by metabolic enzymes, highly complex molecular machines that came into existence during the evolution of modern organisms.

A new study finds benefits to consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass.

The researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone.

It also showed a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle building.  

A new executive summary of an upcoming report adds to vegetarian claims that a normal human diet affects pollutant nitrogen emissions, climate change and land-use across Europe.

The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits and he geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time.

MADISON, Wis. – Marital stress may make people more vulnerable to depression, according to a recent study by University of Wisconsin-Madison researchers and their colleagues.

The long-term study, published in the April 2014 Journal of Psychophysiology, shows that people who experience chronic marital stress are less able to savor positive experiences, a hallmark of depression. They are also more likely to report other depressive symptoms.

The findings are important, says study leader Richard Davidson, UW-Madison William James and Vilas Professor of Psychology and Psychiatry, because they could help researchers understand what makes some people more vulnerable to mental and emotional health challenges.
