Tumors hijack export pathway in cells to resist chemotherapy and fuel disease progression Posted: 19 Dec 2015 11:49 AM PST Scientists have discovered a novel strategy that aggressive sarcomas use to promote drug resistance and cancer's spread plus evidence of how to reverse the process.

Immunotherapy drug more effective than chemotherapy in most patients with advanced lung cancer, study finds Posted: 19 Dec 2015 11:49 AM PST A new study has found immunotherapy to be more effective than chemotherapy in treating most previously treated patients with advanced lung cancer, and demonstrated effectiveness in a wider population of people than previously known to benefit from the therapy.

10,000-year record shows dramatic uplift at Andean volcano Posted: 19 Dec 2015 11:47 AM PST Ongoing studies of a massive volcanic field in the Andes mountains show that the rapid uplift which has raised the surface more than six feet in eight years has occurred many times during the past 10,000 years.

Magnetic reconnection: Magnetic explosions in Northern lights and solar flares Posted: 18 Dec 2015 01:14 PM PST Just under four months into the science phase of the mission, NASA's Magnetospheric Multiscale, or MMS, is delivering promising early results on a process called magnetic reconnection -- a kind of magnetic explosion that's related to everything from the northern lights to solar flares.

Examination of Earth's recent history key to predicting global temperatures Posted: 18 Dec 2015 01:14 PM PST Estimates of future global temperatures based on recent observations must account for the differing characteristics of each important driver of recent climate change, according to a new study.

'Which-hunting' and the hegemony of style guides Posted: 18 Dec 2015 01:14 PM PST A new study reveals just how strong the influence of mass-market books promoting a certain style of writing have had on authors since they were first published in the late 1950s.

Method for detecting latent stage of lymphedema identified Posted: 18 Dec 2015 01:14 PM PST Nursing researchers examined the validity, sensitivity, and specificity of symptoms for detecting breast cancer-related related lymphedema. The study also determined the best clinical cutoff point for the count of symptoms that maximized the sum of sensitivity and specificity.

Turn-taking in communication may be more ancient than language Posted: 18 Dec 2015 01:12 PM PST New research on turn-taking in conversation focuses on its implications for how languages are structured and for how language and communication evolved.

Teens with fewer mental health issues turn to e-cigarettes Posted: 18 Dec 2015 01:12 PM PST Teenagers with moderate mental health problems who may not have considered smoking conventional cigarettes are turning to electronic cigarettes, a new study has found. Today's teens perceive e-cigarettes as less harmful, addictive, smelly and difficult to obtain than conventional cigarettes.

Police shootings of black males: A public health problem Posted: 18 Dec 2015 01:12 PM PST A public health researcher is proposing immediate, concrete steps to stem police shootings of black males.

Bacterium carrying a cloned Bt-gene could help millions infected with roundworms Posted: 18 Dec 2015 01:12 PM PST Intestinal nematodes and roundworms infect more than one billion people worldwide, leading to malnutrition and developmental problems. Now a team of researchers has successfully inserted the gene for a naturally-occurring, insecticidal protein called Bt into a harmless bacterium, which could be incorporated into dairy products, or used as a probiotic to deliver the protein to the intestines of people afflicted with roundworms.

BAP1 mutation passed down over centuries and is associated with high incidence of several cancers Posted: 18 Dec 2015 01:12 PM PST Researchers have discovered that members of 4 families, apparently unrelated and living in different US States, shared the identical mutation of a gene called BAP1 that is associated with a higher incidence of mesothelioma, melanoma, renal carcinoma and other cancers. Through genetic and genealogical studies, it was demonstrated that the families were related, and that they descended from a couple that immigrated to the USA from Germany in the early 1700s.

Swedish researchers reveal security hole Posted: 18 Dec 2015 01:12 PM PST Quantum cryptography is considered a fully secure encryption method, but researchers have discovered that this is not always the case. They found that energy-time entanglement -- the method that today forms the basis for many systems of quantum cryptography -- is vulnerable to attack.

Grid cells: Reading the neural code for space Posted: 18 Dec 2015 01:12 PM PST The cognitive map for spatial navigation is thought to rely on grid cells. Scientists ahave now put forward a mathematical theory that explains key grid-cell features and how these give rise to a neural metric for space.

Rocket gets brief glimpse of a galaxy far, far away Posted: 18 Dec 2015 10:10 AM PST Rocketeers have launched the most sensitive instrument they've ever used to explore outer space, seeking clues to how galaxies grow with the birth of new stars, and how they stop growing.

Carnivore hunting policy and science don't align, researchers find Posted: 18 Dec 2015 10:09 AM PST An international group of biologists say that policies regulating the hunting of large carnivores do not always align with basic scientific data, which can undermine conservation efforts.

Bacteria battle: How one changes appearance, moves away to resist the other Posted: 18 Dec 2015 10:03 AM PST Two types of bacteria found in the soil have enabled scientists to get the dirt on how resistance to antibiotics develops along with a separate survival strategy.The study identifies an atypical antibiotic molecule and the way in which the resistance to that molecule arises, including the identity of the genes that are responsible.

Nanodevices at one-hundredth the cost Posted: 18 Dec 2015 10:03 AM PST Manufacturing microelectromechanical systems -- or MEMS -- has traditionally required sophisticated semiconductor fabrication facilities, which cost tens of millions of dollars to build. New studies now offer hope that that might change.

New method unlocks climate change secrets from the Tibetan ice Posted: 18 Dec 2015 08:05 AM PST

Fish populations at world's second largest freshwater lake Posted: 18 Dec 2015 08:03 AM PST Scientists are studying interactions between the biodiversity of East Africa's Lake Tanganyika and the human communities that live around the lake.
