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.
Many of the choices we make are informed by experiences we've had in the past but we know that sometimes it is better to throw all that out and take a risk on something new.
Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have shown that the brain can temporarily disconnect information about past experience from decision-making circuits, thereby triggering random behavior.
Concrete is the world’s most-used construction material and thus a leading contributor to global warming, producing perhaps 10 percent of industry-generated greenhouse-gas emissions. Industry is already reducing greenhouse emissions, such as by using more natural gas and less coal to generate cost-effective electricity, and a new suggests another low-impact way go green - reducing concrete emissions by more than half and getting a stronger, more durable material using science rather than rationing.
Mother Nature may be out to kill us but we shouldn't take it personally. She is out to kill everything. We just never noticed in the past.
Today, thanks to long-term science projects, we can see how nature pits species off against each other. And biologists are studying streams to optimize how to prevent tallgrass prairies from turning into shrublands and forests.
People who practice yoga and meditation long term can learn to control a computer with their minds faster and better than people with little or no yoga or meditation experience, find biomedical engineers at the University of Minnesota writing in TECHNOLOGY.
The nice thing about telescopes is that we can look back in time - light that is reaching us now may have originated a few hundred million years after the Big Bang, which means astronomers can view the universe as it was when it was much younger.
But sometimes we can be fooled by entire galaxies. DDO 68, otherwise known as UGC 5340, a ragged collection of stars and gas clouds, at first was thought to be a recently-formed galaxy in our own cosmic neighborhood.
But it's not as young as it looks.

For some people, their own standard is much more demanding that anything the outside world could expect. Perfectionism is a bigger risk factor in suicide than it is credited for, says York University Psychology Professor Gordon Flett, who is calling for closer attention to its potential destructiveness, adding that clinical guidelines should include perfectionism as a separate factor for suicide risk assessment and intervention.
A new evolutionary psychology paper says that men and women have different age preferences regarding sexual partners - but it's primarily women realize their preferences.
The human papillomavirus (HPV) vaccine has been controversial in both the United States and European countries like Germany. It prevents about 70% of cervical cancers, cervical cancer is uncommon and highly treatable, and it will need another vaccine before girls who are given it even become adults. Along with those data issues, academic scientists and the public have been engaged in a culture war against pharmaceutical companies - that vaccines are exempt from ordinary lawsuits and that the vaccine was marketed heavily just after an expensive settlement by manufacturer Merck was not lost on the public.
Does simultaneously using a mobile phone, a laptop and other media devices change the structure of our brains? Sure, so did reading that sentence. We all have different experiences and therefore different brains.
No one knows you like you know yourself so if you think your memory is slipping, you may be onto something. Self-reported memory complaints are strong predictors of clinical memory impairment later in life.
Richard Kryscio, PhD, Chairman of the Department of of Biostatistics and Associate Director of the Alzheimer's Disease Center at the University of Kentucky, and colleagues asked 531 people with an average age of 73 and free of dementia if they had noticed any changes in their memory in the prior year. The participants were also given annual memory and thinking tests for an average of 10 years. After death, participants' brains were examined for evidence of Alzheimer's disease.
Surveys are interesting and surveys can sometimes indicate what a certain number of people in a group might be thinking - but so can betting services. In the 2012 election, the Intrade betting service got as many states right in the presidential election as Democratic statistical wunderkind Nate Silver did - and Intrade is mostly Europeans who know nothing at all about American politics.
In our hyperactive media climate, where every incident is proof or not proof of something, it has become common to see claims that wildfires have become worse due to global warming even as American CO2 emissions have dropped.
Scientists have put a fire retardant on claims that Colorado's Front Range wildfires are becoming increasingly severe.
