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.
Welcome to the first big solar flare of 2014.
The sun emitted a significant solar flare peaking at 1:32 p.m. EST on Jan.7, 2014. This is the first significant flare of 2014 and follows on the heels of mid-level flare earlier in the day. Each flare was centered over a different area of a large sunspot group currently situated at the center of the sun, about half way through its 14-day journey across the front of the disk along with the rotation of the sun.
An in vivo study reveals how a protein in the brain, alpha2/delta-1, helps regulate food intake and body weight and may help explain why medications that are prescribed for epilepsy and other conditions that interfere with this protein, such as gabapentin and pregabalin, can cause weight gain.
The alpha2/delta-1 protein has not been linked previously to obesity but the team led by Maribel Rios, Ph.D., associate professor in the department of neuroscience at Tufts University School of Medicine, found that alpha2/delta-1 facilitates the function of another protein called brain-derived neurotrophic factor (BDNF).
African-Americans having a shorter life expectancy and a greater likelihood of suffering from aging-related illnesses at younger ages compared to European-Americans.
A new paper claims that it may be racism impacting aging - at the cellular level. The correlation is that the epidemiologists, doing their part to turn their field into sociology, found signs of accelerated aging in African-American men who who had internalized anti-African-American attitudes or reported high levels of racial discrimination.
There are lots of female scientists in America, women get more Ph.D.s than men, yet in academia they also tend to leave more often because, the claim goes, academia lacks the potential for advancement and the family-friendly policies that the corporate world has.
Astronomers using NASA's Fermi observatory have made the first-ever gamma-ray measurements of a gravitational lens, thanks to B0218+357, located 4.35 billion light-years from Earth in the direction of a constellation Triangulum.
It's not really what it was designed to do. While radio and optical telescopes can resolve and monitor individual blazar images, Fermi's LAT cannot. Instead, the Fermi team exploited a "delayed playback" effect, which
opens new avenues for research, including a novel way to probe emission regions near supermassive black holes. It may even be possible to find other gravitational lenses with data from the Fermi Gamma-ray Space Telescope.
A Johns Hopkins University of research suggests that about 30 minutes of meditation daily may improve symptoms of anxiety and depression, without medication.
The scholars evaluated the degree to which self-reported symptoms changed in people who had a variety of conditions, such as insomnia or fibromyalgia. A minority had been diagnosed with a mental illness.
They were studying so-called "mindfulness meditation", a form of Buddhist self-awareness designed to focus precise attention on the moment at hand, and say it shows promise in alleviating some pain symptoms as well as stress. The researchers controlled for the possibility of the placebo effect but it should be noted that reviews of self-reported claims makes statistical reliability difficult.
No one wants to work for free; doctors have to pay for insurance and employees and their medical school loans, drug companies spend billions on each drug and 95 percent of the time the drugs will never make it to market.
And that chain of money flows to cancer patients as well. Cutting-edge pharmaceuticals are expensive and for poorer people, unless they get a cost waiver from the company, even the co-payment for insurance may be too much.
It's no surprise that when the patient's share of prescription costs becomes too high, many patients skip doses or stop taking medication entirely, according to research conducted at the University of North Carolina.
Residents of a small village on the Fijian island of Yasawa
went boating alone, without life vests, and gave no thought to shimmying up very tall coconut trees.
Inhibitors of both JAK and Src kinases represent promising targets for cancer therapeutics because of the central importance of these kinases in tumor cell proliferation and survival. In addition, in cancer cells activation of JAK has been reported as a compensatory effect in response to Src inhibitor exposure. This implies simultaneous inhibition of both kinases could have a synergy of anti-cancer effects compared to an agent that inhibits one or the other kinases.
A newly discovered system of two white dwarf stars and a superdense pulsar, all packed into a space smaller than the Earth's orbit around the sun, could allow astronomers to tackle the very nature of gravity itself.
The pulsar is 4,200 light-years from Earth and is spinning nearly 366 times per second – it was found to be in close orbit with a white dwarf star and the pair is in orbit with another, more distant white dwarf.
The three-body system is scientists' best opportunity yet to discover a violation of a key concept in Albert Einstein's theory of General Relativity: the strong equivalence principle, which states that the effect of gravity on a body does not depend on the nature or internal structure of that body.
The cockroach in the genus Ectobius is an invasive organism and the most common cockroach inhabiting a large region from northernmost Europe to southernmost Africa.
Astronomers has discovered the first Earth-mass planet that transits its host star and found that KOI-314c is the lightest planet to have both its mass and physical size measured.
Though it weighs the same as Earth, it is 60 percent larger in diameter, meaning that it must have a very thick, gaseous atmosphere, they note.
The team gleaned the planet's characteristics using data from NASA's Kepler spacecraft. KOI-314c orbits a dim, red dwarf star located approximately 200 light-years away. It circles its star every 23 days. The team estimates its temperature to be 220 degrees Fahrenheit, too hot for life as we know it.
