'Stealth' material hides hot objects from infrared eyes
Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, thanks to a new cloaking material that renders objects -- and people -- practically invisible.Source: https://www.sciencedaily.com/releases/2018/06/180622174752.htm
Accurate measurements of sodium intake confirm relationship with mortality
Eating foods high in salt is known to contribute to high blood pressure, but does that linear relationship extend to increased risk of cardiovascular disease and death? Recent cohort studies have contested that relationship, but a new study using multiple measurements confirms it.Source: https://www.sciencedaily.com/releases/2018/06/180622012101.htm
Our intestinal microbiome influences metabolism -- through the immune system
The innate immune system, our first line of defense against bacterial infection, has a side job that's equally important: fine-tuning our metabolism.Source: https://www.sciencedaily.com/releases/2018/06/180621172437.htm
US oil & gas methane emissions 60 percent higher than estimated
The US oil and gas industry emits 13 million metric tons of the potent greenhouse gas methane from its operations each year, 60 percent more than estimated by the US Environmental Protection Agency, according to a new study.Source: https://www.sciencedaily.com/releases/2018/06/180621141154.htm
Antarctic ice sheet is melting, but rising bedrock below could slow it down
An international team of researchers has found that the bedrock below the remote West Antarctic Ice Sheet is rising much more rapidly than previously thought, in response to ongoing ice melt.Source: https://www.sciencedaily.com/releases/2018/06/180621141119.htm
Psychiatric disorders share an underlying genetic basis
Researchers explored the genetic connections between brain disorders at a scale far eclipsing previous work on the subject. The team determined that psychiatric disorders share many genetic variants, while neurological disorders (such as Parkinson's or Alzheimer's) appear more distinct. The results indicate that psychiatric disorders likely have important similarities at a molecular level, which current diagnostic categories do not reflect.Source: https://www.sciencedaily.com/releases/2018/06/180621141059.htm
Einstein proved right in another galaxy
Astronomers have made the most precise test of gravity outside our own solar system. By combining data taken with NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope, the researchers show that gravity in this galaxy behaves as predicted by Albert Einstein's general theory of relativity, confirming the theory's validity on galactic scales.Source: https://www.sciencedaily.com/releases/2018/06/180621141043.htm
A mechanism behind choosing alcohol over healthy rewards is found
Changes in a brain signalling system contribute to the development of alcohol addiction-like behaviors in rats, according to a new study. The findings indicate a similar mechanism in humans.Source: https://www.sciencedaily.com/releases/2018/06/180621141032.htm
Caffeine from four cups of coffee protects the heart with the help of mitochondria
A new study shows that a caffeine concentration equivalent to four cups of coffee promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage.Source: https://www.sciencedaily.com/releases/2018/06/180621141008.htm
Nearly 80 exoplanet candidates identified in record time
Scientists have analyzed data from K2, the follow-up mission to NASA's Kepler Space Telescope, and have discovered a trove of possible exoplanets amid some 50,000 stars. The scientists report the discovery of nearly 80 new planetary candidates, including a particular standout: a likely planet that orbits the star HD 73344, which would be the brightest planet host ever discovered by the K2 mission.Source: https://www.sciencedaily.com/releases/2018/06/180621121901.htm
