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.
Research lab and hospital equipment are two areas where competition drives costs up - if Lab A has a need for a new piece of equipment, Lab B has to get it and that same goes for hospitals. Companies have no reason to undercut each other because the actual market is not that big.
Help may be on the way for a commonly used piece of equipment: the syringe pump. A team led by an engineer at Michigan Technological University has published an open-source library of designs that will let scientists slash its cost. Syringe pumps are used to dispatch precise amounts of liquid, as for drug delivery or mixing chemicals in a reaction. They can also cost hundreds or even thousands of dollars.
Asian-Americans are at higher risk of developing type 2 diabetes than Caucasian-Americans, and prone to develop the disease at lower body weights.
Can Asian heritage and ancestral reliance on a high-fiber, low-fat Asian mean extra risks for those of Asian heritage?
An ultracompact dwarf galaxy known as M60-UCD1 harbors a supermassive black hole – the smallest galaxy known to contain such a massive light-sucking object.
The astronomers used the Gemini North 8-meter optical-and-infrared telescope on Hawaii's Mauna Kea and photos taken by the Hubble Space Telescope to discover that M60-UCD1 has a black hole with a mass equal to 21 million suns. Their finding suggests plenty of other ultracompact dwarf galaxies likely also contain supermassive black holes – and those dwarfs may be the stripped remnants of larger galaxies that were torn apart during collisions with yet other galaxies.
Is chimpanzee intergroup aggression like primitive warfare, an adaptive strategy that gives the perpetrators an edge, or is it the consequence of human activities, such as provisioning - artificial feeding - by researchers or habitat destruction?
A new study of the pattern of intergroup aggression in chimpanzees and pygmy chimpanzees (bonobos), their close relatives, finds that human impact isn't the culprit.
The research project compiled data collected over five decades from 18 chimpanzee (Pan troglodytes) and four bonobo (Pan paniscus) communities.

The United States is one of few wealthy nations without national or socialized health care and, as a result, the Hippocratic Oath has always been paramount. Even when it hasn't been efficient, doctors have tried to save and extend lives.
As a result, the US health care system is not culturally prepared to deal with patients nearing the end of life and their families.

Northwestern Medicine researchers say they have developed the first blood test to diagnose major depression in adults, by measuring the levels of nine RNA blood markers.
RNA molecules are the messengers that interpret the DNA genetic code and carry out its instructions.
Humans may think we are eating paleo - like ancient ancestors - or organic - like before the advent of modern fertilizers and pesticides in the early 1800s - but nothing could be further from the truth. The microbiome of today shares little in common with people of even 100 years ago and if epigenetic claims about diet are true, our genome is different as well.
And nothing should be changed like pigs, which are commonly now descended from Asian and European mixes. But a team of Spanish researchers have obtained the first partial genome sequence of an ancient pig, sequences from remains found at the site of the Montsoriu Castle in Girona.
An older, mechanical car is a closed system - the only way to hack it is to be physically present. But as automobiles become increasingly chip-oriented, any way to update software remotely means the potential to be hacked. You won't be carjacked, you'll be carhackedThe car of the future will be safer, smarter and offer greater high-tech gadgets, but be warned without improved security the risk of car hacking is real, according to a QUT road safety expert.
What is dark matter? No one can say because it can't be detected or measured, but in science inference can help and we know that something is making gravity not work properly at the large scale.
What we know as matter - stars, planets, us and other organisms - is baryonic matter, but it is only a small fraction of the universe. The rest gets lumped under blanket terms like dark energy and dark matter. Dark matter must be a form of matter the particles of which move slowly in comparison with light and interact weakly with electromagnetic radiation.
Parasitic lamprey are a challenge to study but an important one - they are an invasive pest in the Great Lakes but difficult to study under controlled conditions because they live up to 10 years and only spawn for a few short weeks in the summer before they die.
Lamprey are slimy, eel-like parasitic fish with tooth-riddled, jawless, sucking mouths, and rather disgusting to look at, but thanks to their important position on the vertebrate family tree, they can offer important insights about the evolutionary history of brain development, according to a new paper in Nature.
Last decade, science faced an ecological puzzle: under hotter, drier conditions of global warming, forests should have been penalized but instead the rainforests thrived. It isn't the first time - the climate change that caused the death of the dinosaurs gave them a big boost also.
Wine, with its thousands of chemical combinations, can be hard to judge. As numerous studies have shown, getting experts to distinguish between a $4 bottle of wine and a $40 one is in the luck range
Can a nanosensor do better? Researchers at Aarhus University believe they are on that path, at least when it comes to dryness.
