Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
Operator storefronts and portals now account for just 6% of content downloads worldwide, with Google Play and Apple's App Store now comprising nearly 70% between them. The increasing popularity of OTT (Over The Top) stores had led to many operators closing their own mobile storefronts.
Fluoride is good but too much of anything can be bad. However, a filter system developed in India using a medicinal herb is very, very good.
The technology uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.
The divergent lineage of the oldest known genetic branch of the human Y chromosome, the hereditary factor determining male sex, has been pushed back in time.
The new divergent lineage, found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record.
Deleting a specific gene in mice prevents them from becoming obese - even on a high fat diet, according to a two-year study funded by the National Institutes of Health and the U.S. Department of Agriculture and published in the Journal of Lipid Research.
Each year more than 40 million Americans become sick with foodborne infections. Among those who become ill, 128,000 will be hospitalized and 3,000 will die. Foodborne illness also takes a toll on our economy: Broad estimates are that the US loses $77 billion in lost productivity due to people who become sick - adding in more estimates of economic impact a foodborne illness outbreak has on the affected industry.
Usually, a great deal of effort has gone into preventing foodborne illness outbreaks. In 2010, the Obama administration got the Food Safety Management Act passed but it hasn't been funded or implemented, though they have scuttled other food testing divisions of the government that have been focused on preventing contamination of food supply.
The gravitational field surrounding the massive cluster of galaxies called Abell 68 acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies.
Like a fun house mirror, lensing creates a fantasy landscape of arc-like images and mirror images of background galaxies. The foreground cluster is 2 billion light-years away, and the lensed images come from galaxies far behind it.
In this photo, the image of a spiral galaxy at upper left has been stretched and mirrored into a shape similar to that of a simulated alien from the classic 1970s computer game "Space Invaders!" A second, less distorted image of the same galaxy appears to the left of the large, bright elliptical galaxy.
The first evidence for an extinct giant camel in Canada's High Arctic has been revealed. The discovery is based on 30 fossil fragments of a leg bone found on Ellesmere Island, Nunavut and represents the most northerly record for early camels, whose ancestors are known to have originated in North America some 45 million years ago.
The fossils were collected over three summer field seasons (2006, 2008 and 2010) and are about three-and-a-half million years old, dating from the mid-Pliocene Epoch. Other fossil finds at the site suggest this High Arctic camel lived in a boreal-type forest environment, during a global warm phase on the planet.
How did the now extinct Falkland Islands wolf come to be the only land-based mammal there, when they islands are almost 300 miles from Argentina?.
Previous hypotheses floated the idea that the wolf somehow rafted on ice or vegetation, crossed via a now-submerged land bridge or was even semi-domesticated and transported by early South American humans.
Human embryonic stem cells still get all of the attention - a company in California might be able to do a clinical trial for an applied hESC treatment and it was in the news everywhere, but researchers at the University of Minnesota's Lillehei Heart Institute have shown why the un-controversial induced pluripotent stem cell technology may deserve it more. Researchers have combined genetic repair with cellular reprogramming to generate stem cells capable of muscle regeneration in a mouse model for Duchenne Muscular Dystrophy (DMD).
The nucleic and amino acids caught up in the infamous "selfish" segregation distorter (SD) saga may be just inanimate chemical compounds to most of us, but they have put on a soap opera for biologists since the phenomenon was discovered in fruit flies 50 years ago.
When male flies make their sperm, the SD gene (call it "A") manages to rig meiosis — the specialized cell division that makes sex cells — so that maturing sperm that bear chromosomes with the susceptible allele (call that one "a") end up defective and discarded. They never even leave the testes. It is murder, of a sort. Similar selfish systems occur in mammals, including humans.
Remarkably well-preserved fossils of two crocodilians and a mammal previously unknown to science during recent Panama Canal excavations have led to discovering of new species.
The two new ancient, extinct alligator-like animals and an extinct hippo-like species inhabited Central America during the Miocene about 20 million years ago. The fossils shed new light on scientists' understanding of species distribution because they represent a time before the formation of the Isthmus of Panama, when the continents of North and South America were separated by oceanic waters.
It's among the most ancient of questions in history, covering metaphysics, chemistry, biology and theology: What are the origins of life on Earth?
