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.
Combat is correlated in some to depression and substance abuse - post-traumatic stress disorder is part of the lexicon today, real and claimed by clerks who never heard a gunshot while in the military and then a general malaise for people who had any kind of stress.
But soldiers who endure the highest stress - those who kill in the heat of combat - are least likely to self-medicate, according to analysis of data by researchers with the Walter Reed Army Institute of Research and American University.
In "Changes in Alcohol Use after Traumatic Experiences: The Impact of Combat on Army National Guardsmen" in the journal Drug and Alcohol Dependence, they contradict common sociological wisdom.
Advocates for open borders and amnesty for illegal aliens often claim that they are doing jobs legal residents won't. That isn't really true, they just do some jobs for less, because their illegal status makes them unable to compete.
The most dangerous jobs actually pay quite well - and they don't hire people who are not allowed to be in America legally. But jobs that are hazardous and can be done without concern for legal status can be done by illegal aliens - it just doesn't pay well.
Researchers from the U.S. Geological Survey and McGill University have found here is new permafrost forming around Twelvemile Lake in the interior of Alaska.
Twelvemile Lake, and many others like it, have been shrinking over the past thirty years, now being 15 feet shallower than three decades ago.
As the lake recedes, bands of willow shrubs have grown up on the newly exposed lake shores over the past twenty years. What Martin Briggs from the U.S. Geological Survey and Prof. Jeffrey McKenzie from McGill's Dept. of Earth and Planetary Science have just discovered is that the extra shade provided by these willow shrubs has both cooled and dried the surrounding soil, allowing new permafrost to expand beneath them.
Bipolar disorder (BD) is a burdensome conditions, known for its dramatic highs of extreme euphoria, racing thoughts and decreased need for sleep, as well as its profound lows of sadness and despair.
Because it is also associated with a heightened risk of suicide, substance abuse, hypersexuality, familial discord and aggressive behavior, bipolar disorder affects not just those suffering from it, but also those around them — especially their children.
While previous research has shown that children of parents with
bipolar disorder are at a greater risk of developing psychiatric disorders, the psychosocial implications of being raised by parents with bipolar disorder has been ignored — until now.
How were the earth and the moon formed? A giant impact between Earth's ancestor and a planet-sized body occurred
At the Goldschmidt Geochemistry Conference in Sacramento, researchers from the University of Lorraine say that occurred 40 million years after the start of solar system formation, which makes the earth around 60 million years older than previously thought.
Take a quick guess; what law addressed a problem everyone in America knew we had, was passed with overwhelming bipartisan support, it had Republican John Boehner and Democrat Ted Kennedy hugging on the dais, met all of its targets and was still vilified in a political marathon?
It was No Child Left Behind. Under the program, minority scores went up across the board and girls achieved math parity with boys for the first time in history - and we were told teachers hated it. Educators union threatened to withhold millions of dollars in political contributions and a whole lot of votes from Democrats, so after President Barack Obama saw he might lose control of the House in the 2010 election, he began gutting the program.
In April, the Centers for Medicare and Medicaid Services (CMS) released the most detailed data in its history about $77 billion worth of physician billings to Medicare.
In analysis of the data, sites like Science 2.0 and The New York Times showed that only a small percentage of healthcare providers slurp up nearly 25 percent of all federal payments - and unsurprisingly most of them are friends with the politicians who like getting more money from taxpayers and spending it. In 2012, more than $600 million went to just 100 doctors.
What did USC biomedical engineering assistant professor Megan McCain think when she first saw a real human heart, with all of those thin valves that have to open and close every second of our lives?“Wow, there’s a lot of plaques of fat. I need to stop eating French fries.”Nine years later, the “cardiac tissue engineer,” is trying to re-create the human heart on a chip.
People may associate the concept of the chastity belt with medieval Europe but other parts of the animal kingdom used them long before that.Male dwarf spiders, for instance, have evolved a mechanical safeguard to ensure their paternity - mating plugs to block off the genital tract of the female they have just mated with. The larger and older the plug, the better the chances are that other males will not make deposits in a female's sperm storage organ, too. Yes, dwarf spider males (Oedothorax retusus) insert mating plugs into the two copulatory ducts of the females they have mated with.
Last month, the National Climate Assessment report did what the UN Intergovernmental Panel on Climate Change has repeatedly asked science bodies and journalists not to do, no matter how well they mean and how much they want to defend science: it claimed that that the impact of climate change is already being felt in the form of isolated weather events, such as drought, wildfires and heat waves. And that mistake is being used to make policy.
A recent study from the Center for Mind and Brain at the University of California, Davis makes a bold conjecture; that our ability to make choices — and sometimes mistakes — might arise from random fluctuations in the brain's background electrical noise.
The brain has a normal level of 'background noise', says Jesse Bengson, a postdoctoral researcher at the center and first author on the paper.
As electrical activity patterns fluctuate across the brain, decisions can be predicted based on the pattern of brain activity immediately before a decision was made.
Space looks empty but unseen to the naked eye, a wind of charged particles pummels us from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth’s magnetic field, but one of the questions about how this actually occurs is difficult to answer.When two areas with plasma (electrically charged gas) and magnetic fields with different orientations collide, the magnetic fields can be “clipped off” and “reconnected” so that the topology of the magnetic field is changed. This magnetic reconnection can give energy to eruptions on the solar surface, it can change the energy from the solar wind so that it then creates aurora, and it is one of the obstacles to storing energy through processes in fusion reactors.
