Study shows most water in lunar soil generated by solar wind, not result of comet or meteorite impacts

(Phys.org) —A pair of researchers with the Sorbonne Universités, Muséum National d'Histoire Naturelle, has determined that most of the water in the soil on the surface of the moon was formed due to protons in the solar wind colliding with oxygen in lunar dust, rather than from comet or meteorite impacts. In their paper published in Proceedings of the National Academy of Sciences, Alice Stephant and François Robert describe their study and the results they found.

Medicine & Health news

Research suggests people with autism may have an impaired predictive ability

(Medical Xpress)—People with autism might live in a "magical world" in which it's impossible to know what will happen next. Richard Held of the Massachusetts Institute of Technology and colleagues have hypothesized that people with autism have difficulty predicting future events, and that an impaired predictive ability would explain many of the symptoms of autism. The study appears in the Proceedings of the National Academy of Sciences.

A closer look at the blood-brain barrier

(Medical Xpress)—Thousands of people today have various kinds of stimulators placed deep in their brains in the hope of curing their ills. Many others require systems of tubes, catheters, and shunts penetrating deep into their brain ventricles to deliver chemotherapy, analgesics, or to drain overpressurized cerebral liquids. Invariably, as in the commonly used Ommaya reservior for example, these devices have a crude and bulky insertion that is simply plowed through healthy brain tissue, sparing little in its path. To develop more delicate instrumentation for the brain we must imagine working with its natural barriers and protections rather than against them. In other words, we must come to know the wisping membranes that balance the brain's fluid constitution, and the blood brain barrier that seals its vessels, as we would know our own skin.

New genetic variants associated with coffee drinking

A new, large-scale study has identified six new genetic variants associated with habitual coffee drinking. The genome-wide meta-analysis, led by Harvard School of Public Health and Brigham and Women's Hospital researchers, helps explain why a given amount of coffee or caffeine has different effects on different people and provides a genetic basis for future research exploring the links between coffee and health.

A new pathway discovered regulating autoimmune diseases

The main function of the immune system is to protect against diseases and infections. For unknown reasons our immune system attacks healthy cells, tissues and organs in a process called autoimmunity, which can result in diseases such as multiple sclerosis, type 1 diabetes, lupus or rheumatoid arthritis. There are currently no existing cures for these diseases.

I'll take that brain to go: Advancements in the transport of human brain samples and epilepsy research

USC biomedical engineers, neurologists and neurosurgeons develop new methods to advance the study of human brains and epilepsy Studying the human brain is logistically complicated. Living samples of the complex and sensitive organ are limited and difficult to preserve, which means that research on them must be conducted quickly before they expire. Furthermore, the electrodes currently used to record neural activity are largely unsophisticated.

Small molecule 'jams the switch' to prevent inflammatory cell death

(Medical Xpress)—Walter and Eliza Hall Institute scientists have discovered a small molecule that blocks a form of cell death that triggers inflammation, opening the door for potential new treatments for inflammatory disease such as rheumatoid arthritis, Crohn's disease and psoriasis.

Study reveals how deadly MERS virus enters human cells

(Medical Xpress)—Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

The 'cyberwar' against cancer gets a boost from intelligent nanocarriers

Two years ago, Prof. Eshel Ben-Jacob of Tel Aviv University's School of Physics and Astronomy and Rice University's Center for Theoretical Biological Physics made the startling discovery that cancer, like an enemy hacker in cyberspace, targets the body's communication network to inflict widespread damage on the entire system. Cancer, he found, possessed special traits for cooperative behavior and used intricate communication to distribute tasks, share resources, and make decisions.

Candidate H7N9 avian flu vaccine works better with adjuvant

An experimental vaccine to protect people against H7N9 avian influenza prompted immune responses in 59 percent of volunteers who received two injections at the lowest dosage tested, but only if the vaccine was mixed with adjuvant—a substance that boosts the body's response to vaccination. Without adjuvant, immune responses produced by the investigational vaccine were minimal regardless of vaccine dosage, according to findings from a clinical trial sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Sharing makes both good and bad experiences more intense

Undergoing an experience with another person—even if we do it in silence, with someone we met just moments ago—seems to intensify that experience, according to new research published in Psychological Science. The research shows that people who share experiences with another person rate those experiences as more pleasant or unpleasant than those who undergo the experience on their own.

Anorexia/bulimia: A bacterial protein implicated

Eating disorders (ED) such as anorexia nervosa, bulimia, and binge eating disorder affect approximately 5-10% of the general population, but the biological mechanisms involved are unknown. Researchers at Inserm Unit 1073, "Nutrition, inflammation and dysfunction of the gut-brain axis" (Inserm/University of Rouen) have demonstrated the involvement of a protein produced by some intestinal bacteria that may be the source of these disorders. Antibodies produced by the body against this protein also react with the main satiety hormone, which is similar in structure. According to the researchers, it may ultimately be possible to correct this mechanism that causes variations in food intake.
