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.
There is a looming drug crisis approaching and the results of a new paper about the FDA understanding of clinical trials is only going to make it worse.
Right now, the private sector conducts drug development and they are vilified by the media, the public and their competitors in government-funded academia. But drug development fails 95% of the time before getting to market, it costs billions, has to undergo rigorous testing and then has a short window for sales, during which time everyone complains that greedy companies charge too much. As a result of a hostile business climate and increased regulation, drug development is disappearing rapidly, to be replaced by...nothing. Government-controlled science can't do applied research.
What if nearly half of the cars on the road today were replaced by the electric kind, those vehicles that environmentalists and electric vehicle marketing groups claim are "90% efficient" and worth the extra cost? How much better would our emissions scenario be?
It wouldn't make much difference. Even a sharp increase in the use of electric drive cars (hybrid, plug-in hybrid and battery electric) by 2050, up to as much as 42 percent of passenger vehicles in the U.S., would not significantly reduce emissions of high-profile pollutants like carbon dioxide, sulfur dioxide or nitrogen oxides.
Cocaine users display worse memory performance, concentration difficulties, and attentional deficits. They have difficulties understanding the perspective of others, show less emotional empathy, find it more difficult to recognize emotions from voices, behave in a less prosocial manner in social interactions and report fewer social contacts.
So why is it the second most popular drug in Europe, after marijuana?
Scholars at the Psychiatric Hospital of the University of Zurich say the worse emotional empathy was correlated with a smaller social network and the social cognitive deficits contribute to the development and perpetuation of cocaine addiction.
Do you understand the complexities of the brain's working memory? No one really does. Yet everyone knows how much RAM is in their phone or tablet or PC.
Using the RAM analogy, researchers say that working memory - a temporary memory system that keeps information readily accessible for a few minutes - in the brains of primates is a lot like a computer. But it's also in simpler mammals like rodents. RAM does not work like the brain, the brain works like RAM. Ray Kurzweil's singularity just came a little closer after you read that sentence.
Relic moss samples exposed by modern Arctic warming have been found to date as far back as 44,000 years ago, according to radiocarbon dating.
How bad is pollution in China? So bad you can see it from space.Wait, can't you do that in the US? Anyone who has flown into Los Angeles in the morning surely sees pollution. This is different. And worse. Plumes of several anthropogenic pollutants, especially particulate matter and carbon monoxide, at ground level over China can now be detected from space - something that was only possible higher up previously. The team used measurements by the Infrared Atmospheric Sounding Interferometer on board the MetOp satellite and the findings represent a crucial step towards improved monitoring of regional pollution and forecasting of local pollution episodes, especially in China.
Conservationists and animal activists have created a mythology that poaching is mostly illegal hunting for trophies or something like ivory for decoration.It's not the case at all, and that confusion is why anti-poaching efforts are about as effective as the 'War on Drugs' in America.
A new battery that runs on sugar has an "unmatched energy density", according to the team behind it.
Other sugar batteries have been developed but energy density has always been the problem. There is a reason gasoline is still popular after 150 years and that reason isn't big oil marketing, it is that the energy density of gasoline is terrific.
The energy density of this new battery is order of magnitude higher than others, allowing it to run longer before needing to be refueled, said Y.H. Percival Zhang, an associate professor of biological systems engineering at Virginia Tech. They believe the technology could progress enough that it could be running in some devices starting in three years. And they could be cheaper, refillable and biodegradable.
World War II had consequences for continental Europeans. Living in a war-torn country increased the likelihood of a number of physical and mental problems later in life, according to a paper by economists.
Seismic waves penetrating to a depth of almost 200 miles report the discovery of an anomaly that likely is the volcanic mantle plume of the Galapagos Islands - it's just not where geologists and computer modeling had assumed.
You can always tell when someone does not have a lot of experience in something. They are anxious, they start too soon, perhaps confused. With practice and training, situations become rote. Athletes talk about how time slows down when they have locked into what they are doing.
Older brains are more experienced, obviously, and a new paper in Topics in Cognitive Science finds that rather than being a decline in brain function, older brains may take longer to process because they have ever increasing amounts of knowledge.
Near the center of Antarctica, measurements from CryoSat - which exists to make comprehensive measurements of the polar regions in an unusually high-inclination orbit and latitudes of 88° north and south - have detected an unusual pattern in the ice sheet’s elevation. CryoSat carries a radar altimeter that can ‘see’ through clouds and in the dark, providing continuous measurements over areas like central Antarctica that are prone to bad weather and long periods of darkness. The radar measures the surface height variation of ice by timing the interval between the transmission and reception of very short radar pulses as the satellite orbits Earth. CryoSat collects data over Antarctica while passing on northbound and southbound orbits.
