Scientists have discovered a ‘hidden’ mechanism which could explain why some cancer therapies which aim to block tumor blood vessel growth are failing cancer trials. The same mechanism could play the role in the bacterial or viral septic shock — e.g. in Ebola fever — by destabilizing the blood vessels. —> Read More Here
Using whole genomic sequencing, scientists from RIKEN in Japan have for the first time demonstrated the profound effect that chronic hepatitis infection and inflammation can have on the genetic mutations found in tumors of the liver, potentially paving the way to a better understanding of the mechanisms through which these chronic infections can lead to cancer. —> Read More Here
Mussels could be the perfect ‘sentinel’ species to signal the health of coastal ecosystems. But a new study of blue mussels in estuary ecosystems along 600 kilometers of coastline in the Northeast uncovered three key mysteries that will have to be solved first. —> Read More Here

The clime’s speech: Data analysis supports prediction that human language is influenced by environmental factors
(Phys.org)—Human speech is not typically thought to adapt to the environment, and a standard assumption in linguistics is that sound systems are in fact immune to ecological effects. Recently, however, scientists at University of Miami and several Max Planck Institutes in Germany and The Netherlands have, in a single study, predicted that complex tone patterns should not evolve in arid climates by reviewing laryngology data on the negative effects of aridity on vocal cord movement, and – by analyzing climatic and phonological data on over 3,700 languages – found support for their prediction. —> Read More Here
Florida is said to have the highest concentration of freshwater springs on Earth. The Florida Wildlife Corridor #Glades2Gulf Expedition is traversing springs country near the Gulf of Mexico and recently explored several of these wonderful windows into the underground aquifer.
Our first plunge was into the headspring of the Chassahowitzka River before following the river’s 5-mile journey downstream to the Gulf of Mexico. In 2013, the Southwest Florida Water Management District led a restoration of the headspring that pumped out truckloads of sediment and sand. Nearly 4 tons of nitrogen were removed. Though upper springs are clear, the spring runs and river are still challenged by toxic algae fed by nutrient-laden runoff from development in the springshed.
Hats off to researchers in California. They’ve taken what appears to be a big step toward the development of a cure for hair loss, a condition that affects 50 million men and 30 million women in the U.S. alone.
The scientists, working at the Sanford-Burnham Medical Research Institute in La Jolla, Calif., showed that stem cells derived from human skin can be used to grow hair–at least in mice.
“The method is a marked improvement over current methods that rely on transplanting existing hair follicles from one part of the head to another,” Dr. Alexey Terskikh, an associate professor at the institute and a member of the team of researchers who demonstrated the experimental technique, said in a written statement. “Our stem cell method provides an unlimited source of cells from the patient for transplantation and isn’t limited by the availability of existing hair follicles.”
In other words, unlike conventional hair transplantation and other hair restoration treatments now in use, the technique could–at least in theory–grow lots of hair on the heads of men and women who are completely bald.
That would be a very big deal.

Crystal light: New family of light-converting materials points to cheaper, more efficient solar power and LEDs
Engineers have shone new light on an emerging family of solar-absorbing materials that could clear the way for cheaper and more efficient solar panels and LEDs. The materials, called perovskites, are particularly good at absorbing visible light, but had never been thoroughly studied in their purest form: as perfect single crystals. Using a new technique, researchers grew large, pure perovskite crystals and studied how electrons move through the material as light is converted to electricity. —> Read More Here
