Diversion of an HIV Vaccine Immune Response by Antibodies Reactive with Gut Microbiome

A recent HIV vaccine trial testing the HIV envelope as an immunogen was unsuccessful for protection against HIV infection. A new study has found that this vaccine selectively recruited antibodies reactive with both the HIV envelope and common intestinal microbes — a phenomenon previously reported by the same investigators to occur in the setting of acute HIV infection.

An Exceptional Planetary System Discovered in Cassiopeia by Astronomers of UNIGE

Astronomers from the University of Geneva (UNIGE) and members of the NCCR PlanetS have teased out a secret planetary system hiding in the arms of Cassiopea, just 21 light years away from us. The remarkable system, named HD219134, hosts one outer giant planet and three inner super-Earths, one of which transits in front of the star. The transiting super-Earth has a density similar to the Earth’s.

Telescopes Team Up to Find Distant Uranus-Sized Planet Through Microlensing

Astronomers using NASA's Hubble Space Telescope and the W. M. Keck Observatory in Hawaii have confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing. These results appear in two papers in The Astrophysical Journal.

Health experts have warned for years that the overuse of antibiotics is creating “superbugs” able to resist drugs treating infection. Now scientists at Indiana University and elsewhere are finding evidence that an invisible war between microorganisms may also be catching humans in the crossfire.

Older Americans receive prescriptions for mental health drugs at more than twice the rate that younger adults do, but they’re much less likely to be getting their mental health care from a psychiatrist, a new study shows. Some seniors could be at risk of problems caused interactions between drugs.

Tiny Grains of Rice Hold Big Promise for Greenhouse Gas Reductions, Bioenergy

ricecomparison.jpg

Rice is the staple food for more than half of the world’s population, but the paddies it’s grown in contributes up to 17 percent of global methane emissions -- about 100 million tons a year. Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane, more starch for a richer food source and biomass for energy production, as announced in the July 30 edition of Nature and online.
