11:22 AM | Astronomy: Radio telescopes settle controversy over distance to Pleiades
A worldwide network of radio telescopes measured the distance to the famous star cluster the Pleiades to an accuracy within 1 percent. The result resolved a controversy raised by a satellite’s measurement that now is shown to be wrong. The incorrect measurement had challenged standard models of star formation and evolution. The astronomers studied the …

11:20 AM | Genomic sequencing reveals mutations, insights into 2014 Ebola outbreak
In response to an ongoing, unprecedented outbreak of Ebola virus disease in West Africa, a team of researchers has rapidly sequenced and analyzed more than 99 Ebola virus genomes. Their findings could have important implications for rapid field diagnostic tests. For the current study, researchers sequenced 99 Ebola virus genomes collected from 78 patients diagnosed …

11:17 AM | New DNA study unravels the settlement history of the New World Arctic
A new DNA study unravels the settlement history of the New World Arctic. We know people have lived in the New World Arctic for about 5,000 years. Archaeological evidence clearly shows that a variety of cultures survived the harsh climate in Alaska, Canada and Greenland for thousands of years. Despite this, there are several unanswered …

11:08 AM | Detecting neutrinos, physicists look into the heart of the sun
Using one of the most sensitive neutrino detectors on the planet, physicists have directly detected neutrinos created by the ‘keystone’ proton-proton fusion process going on at the sun’s core for the first time. The pp reaction is the first step of a reaction sequence responsible for about 99 percent of the Sun’s power, Pocar explains. …

11:06 AM | Early growth of giant galaxy, just 3 billion years after the Big Bang, revealed
The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Astronomers identified a dense galactic core, dubbed “Sparky,” using a combination …

11:04 AM | Marijuana compound may offer treatment for Alzheimer’s disease, study suggests
Extremely low levels of the compound in marijuana known as delta-9-tetrahydrocannabinol, or THC, may slow or halt the progression of Alzheimer’s disease, a recent study from neuroscientists suggests. Researchers from the USF Health Byrd Alzheimer’s Institute showed that extremely low doses of THC reduce the production of amyloid beta, found in a soluble form in …

11:01 AM | Shared biology: Powerful commonalities in biological activity
Researchers analyzing human, fly, and worm genomes have found that these species have a number of key genomic processes in common, reflecting their shared ancestry. The findings offer insights into embryonic development, gene regulation and other biological processes vital to understanding human biology and disease. Launched in 2007, the goal of modENCODE is to create …

10:58 AM | Evolution used similar molecular toolkits to shape flies, worms, and humans
Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression, according to a massive analysis of genomic data. Two related studies tell a similar story: even though humans, worms, and flies bear little obvious similarity to each other, evolution used remarkably similar molecular toolkits to …

10:51 AM | Orion Nebula may be brimming with pebble-size particles
Astronomers have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles — planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars. Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the …

11:40 PM | U.S. Announces Plans to Send Tanks and Troops to Eastern Europe
Following reports earlier this week of over 1,000 Russian troops and more than 100 Russian tanks crossing over into Ukraine, the U.S. has announced plans to send American tanks and troops to participate in military drills alongside the United States’ NATO allies. About 600 troops from the 1st Brigade, 1st Cavalry Division (also known as the “Iron Horse brigade”) will deploy from their base in Fort Hood, Texas in October. But unlike the 173rd Airborne Brigade troops […]

sagansense: child-of-thecosmos: Radio and television broadcasting may be only a brief passing phase in our technological development. When we imagine alien civilizations broadcasting signals with radio telescopes, are we any different from earlier generations who imagined riding cannon shells to the moon? Civilizations even slightly more advanced than ours may have already moved on to some other mode of communication, one that we have yet to discover or even imagine. Their messages could be […]

7:00 PM | Aerogel Monoliths Made Of Copper Nanowires And PVA Nano-Glue
Bending, stretching, twisting, folding, modern materials that are light, flexible and highly conductive are the future of products like artificial skin or electronic paper.  But these "aerogel monoliths" have required precious gold and silver nanowires, which keeps them squarely in the field of basic research.  Making such concepts affordable with copper nanowires and a PVA "nano glue" could be a game-changer, and researchers at Monash University and the Melbourne Centre for […]

5:08 PM | Will We Meet ET Microbes On Mars? Why We Should Care Deeply About Them - Like Tigers
Many people care deeply about the possibility of tigers, lemurs and such like becoming extinct in the wild. I'd like to suggest that we care as much about the possibility of microbes on Mars and elsewhere in our solar system becoming extinct through human activities. So what's so special about microbes on Mars? Well first, the uniqueness. Tigers are closely related to cats. They are wonderful and remarkable creatures - and would be a tremendous shame to lose them - but basically it's the […]
