Titan glowing at dusk and dawn Posted: 22 Oct 2014 02:01 PM PDT New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one. |
Finally: Missing link between vitamin D, prostate cancer Posted: 22 Oct 2014 01:40 PM PDT A new study offers compelling evidence that inflammation may be the link between vitamin D and prostate cancer. Specifically, the study shows that the gene GDF-15, known to be upregulated by vitamin D, is notably absent in samples of human prostate cancer driven by inflammation. |
Real-time tracking system developed to monitor dangerous bacteria inside body Posted: 22 Oct 2014 01:40 PM PDT Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, researchers working with mice report they have devised a way to detect and monitor in real time infections with dangerous Gram-negative bacteria. These increasingly drug-resistant bacteria are responsible for a range of diseases, including fatal pneumonias and various bloodstream or solid-organ infections acquired in and outside the hospital. |
Paralyzed patients have weaker bones, higher risk of fractures than expected Posted: 22 Oct 2014 01:39 PM PDT People paralyzed by spinal cord injuries lose mechanical strength in their leg bones faster, and more significantly, than previously believed, putting them at greater risk for fractures from minor stresses, according to a study by researchers. The results suggest that physicians should begin therapies for such patients sooner to maintain bone mass and strength, and should think beyond standard bone density tests when assessing fracture risk in osteoporosis patients. |
Bipolar disorder discovery at the nano level Posted: 22 Oct 2014 12:47 PM PDT A nano-sized discovery helps explain how bipolar disorder affects the brain and could one day lead to new drug therapies to treat the mental illness, researchers report. |

Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans Posted: 22 Oct 2014 11:36 AM PDT BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans. Subjects studied showed a rapid increase of BPA in their blood after using a skin care product and then touching a store receipt with BPA. |
Baby cries show evidence of cocaine exposure during pregnancy Posted: 22 Oct 2014 11:36 AM PDT A new study provides the first known evidence of how a similar acoustic characteristic in the cry sounds of human infants and rat pups may be used to detect the harmful effects of prenatal cocaine exposure on nervous system development. |
Highly effective new anti-cancer drug shows few side effects in mice Posted: 22 Oct 2014 11:35 AM PDT A new drug, OTS964, can eradicate aggressive human lung cancers transplanted into mice, scientists report. It inhibits the action of a protein that is overproduced by several tumor types but is rarely expressed in healthy adult tissues. Without it, cancer cells fail to complete the cell-division process and die. |
Fast modeling of cancer mutations Posted: 22 Oct 2014 10:14 AM PDT A new genome-editing technique enables rapid analysis of genes mutated in tumors, researchers report. Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with cancer. However, sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process -- until now. |
As permafrost soils thaw soil microbes amplify global climate change Posted: 22 Oct 2014 10:14 AM PDT Scientists have discovered how an invisible menagerie of microbes in permafrost soils acts as global drivers of Earth processes such as climate via gas exchange between soils and the atmosphere. These findings will help climate modelers more accurately predict Earth's future climate. |
How lymph nodes expand during disease Posted: 22 Oct 2014 10:06 AM PDT The same specialized immune cells that patrol the body and spot infections also trigger the expansion of immune organs called lymph nodes, scientists have discovered. The immune system defends the body from infections and can also spot and destroy cancer cells. Lymph nodes are at the heart of this response, but until now it has never been explained how they expand during disease. |
Posted: 22 Oct 2014 10:06 AM PDT The HARPS instrument at ESO's La Silla Observatory in Chile has been used to make the most complete census of comets around another star ever created. Astronomers have studied nearly 500 individual comets orbiting the star Beta Pictoris and has discovered that they belong to two distinct families of exocomets: old exocomets that have made multiple passages near the star, and younger exocomets that probably came from the recent breakup of one or more larger objects. |
Some scientists share better than others Posted: 22 Oct 2014 09:35 AM PDT Some scientists share better than others. While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go. New research explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built, said a co-author of the paper. |
Bariatric surgery success influenced by how people view their own weight Posted: 22 Oct 2014 09:35 AM PDT Negative feelings about one's own weight, known as internalized weight bias, influence the success people have after undergoing weight loss surgery, according to research. The study is considered the first and only study to examine internalized weight bias in relation to post-surgical weight loss success in adults. |
Karakoram glacier anomaly resolved, a cold case of climate science Posted: 22 Oct 2014 09:35 AM PDT Researchers may have hit upon an answer to a climate-change puzzle that has eluded scientists for years, namely why glaciers in the Karakoram range of the Himalayas have remained stable and even increased in mass while glaciers nearby and worldwide have been receding. Understanding the 'Karakoram anomaly' could help gauge the future availability of water for hundreds of millions of people. |
Shifting precipitation patterns affect tea flavor, health compounds, study shows Posted: 22 Oct 2014 09:34 AM PDT Major antioxidant compounds that determine tea health properties and taste fell up to 50 percent during an extreme monsoon, a study concludes. The findings are based on samples taken from tea gardens in southwest China. The researchers collected samples from two extreme weather events -- an extreme drought and an extreme monsoon -- and performed a chemical analysis of the samples. |
Lessons from 'Spanish flu,' nearly 100 years later Posted: 22 Oct 2014 09:34 AM PDT Just in time for flu season, a new study of 'the mother of all pandemics' could offer insight into infection control measures for the flu and other epidemic diseases. Researchers studied the evolution of the 1918 influenza pandemic, aka the "Spanish flu." In 1918, the virus killed 50 million people worldwide, 10 to 20 million of whom were in India. In the United States alone, the Spanish flu claimed 675,000 lives in nine months. |
Brain simulation raises questions Posted: 22 Oct 2014 09:34 AM PDT What does it mean to simulate the human brain? Why is it important to do so? And is it even possible to simulate the brain separately from the body it exists in? These questions are discussed in a new paper. |
Drones help show how environmental changes affect the spread of infectious diseases Posted: 22 Oct 2014 09:34 AM PDT Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new article, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases. |
Lose the weight, not the potatoes, study says Posted: 22 Oct 2014 09:33 AM PDT People can eat potatoes and still lose weight, a new study demonstrates. The study sought to gain a better understanding of the role of calorie reduction and the glycemic index in weight loss when potatoes are included in the diet. "Some people have questioned the role of potatoes in a weight loss regimen because of the vegetable's designation as a high glycemic index food," explained the lead investigator of the study. "However, the results of this study confirm what health professionals and nutrition experts have said for years: it is not about eliminating a certain food or food groups, rather, it is reducing calories that count." |
Project screenings show need for more mental health services in youth detention Posted: 22 Oct 2014 09:32 AM PDT More mental health screenings and services are needed for juvenile offenders, experts say. The intent of this study was to implement mental health screening; determine the percentage of youth detainees in need of services; assess the availability and extent of detention center mental health follow-up and referral services; and assess whether a disparity exists due to the size and geographic location of the detention center. |
Aging in place: Does a loved one need a geriatric assessment? Posted: 22 Oct 2014 09:32 AM PDT By a tremendous margin – over 95 percent – older Americans choose to live at home or with relatives. Families making that choice should consider seeking the assistance of a geriatric specialist, especially when they see changes in their loved one's behavior, an expert says. |

Quality of biopsy directly linked to survival in patients with bladder cancer Posted: 22 Oct 2014 09:30 AM PDT The quality of diagnostic staging using biopsy in patients with bladder cancer is directly linked with survival, meaning those that don't get optimal biopsies are more likely to die from their disease, researchers have shown for the first time. |
Mathematical model shows how brain remains stable during learning Posted: 22 Oct 2014 09:30 AM PDT Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists. Neuronal networks form a learning machine that allows the brain to extract and store new information from its surroundings via the senses. Researchers have long puzzled over how the brain achieves sensitivity and stability to unexpected new experiences during learning -- two seemingly contradictory requirements. |
Human skin cells reprogrammed directly into brain cells Posted: 22 Oct 2014 09:30 AM PDT Scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntington's disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types, report researchers. |
An effective, cost-saving way to detect natural gas pipeline leaks Posted: 22 Oct 2014 07:35 AM PDT Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Scientists say they have now developed a new software-based method that finds leaks even when they're small, which could help prevent serious incidents -- and save money for customers and industry. |
A 'Star Wars' laser bullet -- this is what it really looks like Posted: 22 Oct 2014 07:35 AM PDT Action-packed science-fiction movies often feature colourful laser bolts.

Protecting us from our cells: Research could speed trials to treat auto-immune diseases Posted: 22 Oct 2014 05:42 AM PDT Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body's natural defense against this 'friendly fire', scientists have found. The findings are especially exciting because IGF-1 is already approved for use in patients, which could speed up the move to clinical trials for treating auto-immune diseases. |
Genes exhibit different behaviours in different stages of development Posted: 22 Oct 2014 05:42 AM PDT The effect that genes have on our brain depends on our age, researchers say. It has been known for a number of years that particular genetic variations are of importance for the functioning of neural circuits in the brain. Just how these effects differ in the various stages of life has until recently not been fully understood. This international study has been able to demonstrate that genetic variations at different times in our lives can actually have opposite effects on the brain, which provides an explanation for the differences that clinicians observe in the psychiatric symptoms and response to medications of adolescents and adults. |
Cheaper silicon means cheaper solar cells Posted: 22 Oct 2014 05:42 AM PDT Researchers have pioneered a new approach to manufacturing solar cells that requires less silicon and can accommodate silicon with more impurities than is currently the standard. Those changes mean that solar cells can be made much more cheaply than at present. |
