There is a discovery out there that has shown some success with multiple sclerosis, with amyotrophic lateral sclerosis (ALS - Lou Gehrig's Disease), and has even improved the function of aging hearts – but despite all that, you have probably never heard of it.

No, this is not a story about how a revolutionary breakthrough got bought up by some giant corporation and stuck in a warehouse to protect their profits - it is instead a story about how potentially good products may never see the light of day for lots of reasons. It happens more often than you think.

Images of Saturn's auroras as the planet's magnetic field is battered by charged particles from the Sun have led a team to claim decisive evidence for the hypothesis that Saturn's auroral displays are often caused by the dramatic collapse of its "magnetic tail".

Just like comets, planets such as Saturn and the Earth have a "tail" – known as the magnetotail – that is made up of electrified gas from the Sun and flows out in the planet's wake.

When a particularly strong burst of particles from the Sun hits Saturn, it can cause the magnetotail to collapse, with the ensuing disturbance of the planet's magnetic field resulting in spectacular auroral displays. A very similar process happens here on Earth.

New research does not support claims that fluoridating water adversely affects children's mental development and adult IQ.

The researchers were testing the claim that exposure to levels of fluoride used in community water fluoridation is toxic to the developing brain and can cause IQ deficits.  The data used in the American Journal of Public Health article used data from the Dunedin Multidisciplinary Study, which   has followed nearly all aspects of the health and development of around 1,000 people born in Dunedin in 1972-1973 up to age 38.  

ATS 2014, SAN DIEGO ─ Despite being touted by their manufacturers as a healthy alternative to cigarettes, e-cigarettes appear in a laboratory study to increase the virulence of drug- resistant and potentially life-threatening bacteria, while decreasing the ability of human cells to kill these bacteria

Researchers at the VA San Diego Healthcare System (VASDHS) and the University of California, San Diego (UCSD), tested the effects of e-cigarette vapor on live methicillin-resistant Staphylococcus aureus (MRSA) and human epithelial cells. MRSA commonly colonizes the epithelium of the nasopharynx, where the bacteria and epithelial cells are exposed constantly to inhaled substances such as e-cigarette vapor and cigarette smoke.

An analysis that included approximately 7 million hospitalizations finds that sepsis contributed to 1 in every 2 to 3 deaths, and most of these patients had sepsis at admission, according to a study published by JAMA. The study is being released early online to coincide with its presentation at the American Thoracic Society International Conference.

Sepsis, the inflammatory response to infection, affects millions of patients worldwide. However, its effect on overall hospital mortality has not been fully measured, according to background information in the article.

Physicists say they have discovered how to create matter from light - a feat thought impossible when the idea was first theorized 80 years ago. There is just one problem. In order to test the newest hypothesis, a new& machine would have to be built.

In just one day over several cups of coffee in a tiny office at Imperial College London, three physicists believe they worked out a relatively simple way to physically prove a theory first devised by scientists Breit and Wheeler in 1934. Yes, they solved a puzzle that has eluded the rest of the world in an afternoon. Well, on paper.

A University of Florida study shows that the same bacteria that cause gum disease also promotes heart disease – a discovery that could change the way heart disease is diagnosed and treated. Researchers report their findings today at the annual meeting of the American Society for Microbiology.

"We report evidence that introduction of oral bacteria into the bloodstream in mice increased risk factors for atherosclerotic heart disease. Our hope is that the American Heart Association will acknowledge causal links between oral disease and increased heart disease. That will change how physicians diagnose and treat heart disease patients," says Irina M. Velsko, a graduate student in the University of Florida's College of Medicine, who presented the data.

There is a reason why peeing in your house is not actually a good idea - but some doctors have perpetuated the idea that urine is sterile by using that as a test for urinary tract infections.

Not that you should ever use Wikipedia for anything, but the non-expert hacktivists there botch the urine entry as further evidence. And every year the myth is debunked but it persists.

Bacteria live in the bladders of healthy women, researchers from Loyola University Chicago noted again, this time at the 114th General Meeting of the American Society for Microbiology in Boston.

Patients with pancreatic cancer have a different and distinct profile of specific bacteria in their saliva compared to healthy controls and even patients with other cancers or pancreatic diseases, according to research presented today at the annual meeting of the American Society for Microbiology. These findings could form the basis for a test to diagnose the disease in its early stages.

"Our studies suggest that ratios of particular types of bacteria found in saliva may be indicative of pancreatic cancer," says Pedro Torres of San Diego State University who presented the research.
