Urban seismic network detects human sounds Posted: 29 Oct 2014 05:39 PM PDT When listening to the Earth, what clues can seismic data reveal about the impact of urban life? Although naturally occurring vibrations have proven useful to seismologists, until now the vibrations caused by humans haven't been explored in any real depth. Researchers have described their efforts to tap into an urban seismic network to monitor the traffic of trains, planes, automobiles and other modes of human transport. |
Plump turtles swim better: First models of swimming animals Posted: 29 Oct 2014 05:37 PM PDT |
Innovative study utilizing video games shows sleep apnea may affect memory of everyday events Posted: 29 Oct 2014 05:37 PM PDT Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research suggests. The study demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory in humans even when other sleep stages are intact. |
Low carb, high fat diets may reduce seizures in tough-to-treat epilepsy Posted: 29 Oct 2014 05:37 PM PDT |
Novel ultrasound technology to screen for heart conditions developed by engineers Posted: 29 Oct 2014 11:56 AM PDT Engineers have determined, for the first time, the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart, and have developed a novel ultrasound technology that makes screening cheaper and much easier, making it possible to reach a large number of people and even infants. |
Ammonium source in open ocean tracked by researchers Posted: 29 Oct 2014 11:56 AM PDT To understand the extent to which human activities are polluting Earth's atmosphere and oceans, it's important to distinguish human-made pollutants from compounds that occur naturally. A new study finds that deposition of ammonium, a source of nitrogen pollution, over the open ocean comes mostly from natural marine sources, and not from human activity. |
Tiny carbon nanotube pores make big impact Posted: 29 Oct 2014 11:56 AM PDT Scientists have created a new kind of ion channel based on short carbon nanotubes, which can be inserted into synthetic bilayers and live cell membranes to form tiny pores that transport water, protons, small ions and DNA. These carbon nanotube "porins" have significant implications for future health care and bioengineering applications. |

Clean smell doesn't always mean clean air Posted: 29 Oct 2014 11:12 AM PDT Scientists are taking a closer look at aerosol formation involving an organic compound -- called limonene -- that provides the pleasant smell of cleaning products and air fresheners. This research will help to determine what byproducts these sweet-smelling compounds are adding to the air while we are using them to remove germs and odors. |
Dozens of genes associated with autism in new research Posted: 29 Oct 2014 11:12 AM PDT Two major genetic studies of autism, involving more than 50 laboratories worldwide, have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms that govern whether, when, and how genes are activated overall. |
Planet-forming lifeline discovered in a binary star system Posted: 29 Oct 2014 11:12 AM PDT |
In autoimmune diseases affecting millions, researchers pinpoint genetic risks, cellular culprits Posted: 29 Oct 2014 11:12 AM PDT Scores of autoimmune diseases afflicting one in 12 Americans -- ranging from type 1 diabetes, to multiple sclerosis (MS), to rheumatoid arthritis, to asthma -- mysteriously cause the immune system to harm tissues within our own bodies. Now, a new study pinpoints the complex genetic origins for many of these diseases, a discovery that may lead to better diagnosis and ultimately to improved treatments. |

Contamination likely explains 'food genes in blood' claim Posted: 29 Oct 2014 11:12 AM PDT |
Posted: 29 Oct 2014 10:34 AM PDT Many factors, both genetic and environmental, have been blamed for increasing the risk of a diagnosis of schizophrenia. Some, such as a family history of schizophrenia, are widely accepted. Others, such as infection with Toxoplasma gondii, a parasite transmitted by soil, undercooked meat and cat feces, are still viewed with skepticism. A new study used epidemiological modeling methods to determine the proportion of schizophrenia cases that may be attributable to T. gondii infection. The work suggests that about one-fifth of cases may involve the parasite. |

Projecting a robot's intentions: New spin on virtual reality helps engineers read robots' minds Posted: 29 Oct 2014 09:45 AM PDT In a darkened, hangar-like space inside MIT's Building 41, a small, Roomba-like robot is trying to make up its mind. Standing in its path is an obstacle — a human pedestrian who's pacing back and forth. To get to the other side of the room, the robot has to first determine where the pedestrian is, then choose the optimal route to avoid a close encounter. As the robot considers its options, its "thoughts" are projected on the ground: A large pink dot appears to follow the pedestrian — a symbol of the robot's perception of the pedestrian's position in space. |

Largest ever dataset of individual deaths in Africa, SE Asia reveals changing health Posted: 29 Oct 2014 09:45 AM PDT |
Liberal or conservative? Reactions to disgust are a dead giveaway Posted: 29 Oct 2014 09:45 AM PDT The way a person's brain responds to a single disgusting image is enough to reliably predict whether he or she identifies politically as liberal or conservative. As we approach Election Day, the researchers say that the findings come as a reminder of something we all know but probably don't always do: 'Think, don't just react.' |
Can social media help stop the spread of HIV? Posted: 29 Oct 2014 09:45 AM PDT In addition to providing other potential benefits to public health, all of those tweets and Facebook posts could help curb the spread of HIV. Although public health researchers have focused early applications of social media on reliably monitoring the spread of diseases such as the flu, a new article tells of a future in which social media might predict and even change biomedical outcomes. |
EEG test to help understand, treat schizophrenia Posted: 29 Oct 2014 09:43 AM PDT |
Potential target for treating triple-negative breast cancer identified Posted: 29 Oct 2014 09:43 AM PDT A protein that could prevent metastasis and recurrence of breast cancer has been identified by researchers. So-called "triple-negative" breast cancer represents between 12 and 17 percent of all breast cancers. It derives its name from the lack of receptors for estrogen, progesterone and Her2. The absence of these receptors rules out proven hormone therapies such as tamoxifen. Triple-negative breast cancer can be more aggressive and is more likely to recur than other breast cancers. |
Cinema-like environment helps audiences become immersed in movies even when shown on cell phones Posted: 29 Oct 2014 07:26 AM PDT If the surroundings are designed to be sufficiently stimulating, even a simple computer screen is enough to generate an intense cinematic experience. After observing some 300 study subjects, researchers concluded that the angle of viewing does not play a vital role in the cinematic experience, thus disproving various hypotheses. According to the results of their study, the presence of so-called contextual visual cues plays a greater role in actually drawing viewers into a movie. |
New solar power material converts 90 percent of captured light into heat Posted: 29 Oct 2014 06:54 AM PDT A multidisciplinary engineering team developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. |

Gentle caffeine boost for premature babies Posted: 29 Oct 2014 06:54 AM PDT |
Genome sequencing of the jujube tree completed Posted: 29 Oct 2014 06:54 AM PDT The complete, high quality sequencing of the jujube genome has been announced by researchers. Jujube is the most economically important member of the Rhamnaceae family, and the jujube genome is particularly difficult to sequence due the high level of heterozygosity and other complicating factors. It is the first time that a genome in the Rhamnaceae, Buckthorn, family has been sequenced. |
Nestling birds struggle in noisy environments Posted: 29 Oct 2014 06:53 AM PDT Unable to fly, nestling birds depend on their parents for both food and protection: vocal communication between parents and offspring helps young birds to determine when they should beg for food and when they should crouch in the nest to avoid a predator seeking an easy meal. A group of researchers has found that ambient, anthropomorphic noise -- from traffic, construction and other human activities -- can break this vital communications link, leaving nestlings vulnerable or hungry. |
To reap the brain benefits of physical activity, just get moving Posted: 29 Oct 2014 06:52 AM PDT |
Posted: 29 Oct 2014 06:52 AM PDT Researchers have deciphered the role of nanostructures around brain cells in the central nervous system. An accumulation of a protein called amyloid-beta into large insoluble deposits called plaques is known to cause Alzheimer's disease. One aspect of this illness that has not received much attention is which role the structure of the brain environment plays. How do macromolecules and macromolecular assemblies, such as polysaccharides, influence cell interaction in the brain? |
Aortic valve replacement appears safe, effective in very elderly patients Posted: 29 Oct 2014 06:51 AM PDT |
Genome sequenced of enterovirus D68 circulating in St. Louis Posted: 29 Oct 2014 06:50 AM PDT |
ECG on the run: Continuous ECG surveillance of marathon athletes is feasible Posted: 29 Oct 2014 05:41 AM PDT The condition of an athlete's heart has for the first time been accurately monitored throughout the duration of a marathon race. The real-time monitoring was achieved by continuous electrocardiogram (ECG) surveillance and data transfer over the public mobile phone network to a telemedicine center along the marathon route. This new development in cardiac testing in endurance athletes, said investigators, 'would allow instantaneous diagnosis of potentially fatal rhythm disorders.' |
Diets high in fruit, vegetables, whole grains and nuts among factors to lower first-time stroke risk Posted: 29 Oct 2014 05:41 AM PDT |
Brain abnormalities found in chronic fatigue patients Posted: 29 Oct 2014 05:41 AM PDT |
Saving lots of computing capacity with a new algorithm Posted: 29 Oct 2014 05:40 AM PDT The control of modern infrastructure such as intelligent power grids needs lots of computing capacity. Scientists have developed an algorithm that might revolutionize these processes. With their new software researchers are able to forego the use of considerable amounts of computing capacity, enabling what they call micro mining. |
Ghrelin stimulates an appetite for drinking alcohol Posted: 29 Oct 2014 05:40 AM PDT Ghrelin is a hormone released by the stomach and it stimulates appetite and food intake. Alcohol is commonly viewed as a psychoactive substance that primarily affects brain function, but it is also a highly caloric food. This knowledge, combined with findings from animal studies, led researchers to the hypothesis that ghrelin has the potential to stimulate alcohol craving. |
Evolution of competitiveness: Scientists explain diversity in competitiveness Posted: 29 Oct 2014 05:40 AM PDT Virtually all organisms in the living world compete with members of their own species. However, individuals differ strongly in how much they invest into their competitive ability. Some individuals are highly competitive and eager to get access to high-quality resources, while others seem to avoid competition, instead making prudent use of the lower-quality resources that are left over for them. Moreover, the degree of competitiveness in animal and human societies seems to fluctuate considerably over time. A new study sheds some new light on these findings. |
Prenatal phthalate exposures and anogenital distance in swedish boys Posted: 29 Oct 2014 05:36 AM PDT The first study to examine prenatal exposure to the phthalate DiNP finds it is associated with a shorter anogenital distance (AGD) in Swedish boys at the age of 21 months. These findings raise concern since animal research has linked DiNP exposure to a shorter AGD, and studies on humans have related shorter AGD to male genital birth defects as well as impaired reproductive function in adult males, and the levels of DiNP metabolites in humans are increasing globally. |
Gold nanoparticle chains confine light to the nanoscale Posted: 29 Oct 2014 05:36 AM PDT Physicists and chemists have shown that crystalline gold nanoparticles aligned and then fused into long chains can be used to confine light energy down to the nanometer scale while allowing its long-range propagation. Light can be used to transmit information. This property is, for instance, used in fiber optics, and provides an interesting alternative to microelectronics. |
The secret life of the sea trout Posted: 29 Oct 2014 05:36 AM PDT Sea trout, also known as brown trout, live complicated lives. Like salmon, they begin their lives in a river, hatched from eggs that were laid in small nests, called redds. As the young fish mature, they go through several developmental stages, all of which involve substantial physiological changes. The most important stage from this perspective is when the fish becomes a smolt, after about 2 years. Entering the smolt stage is like being given a passport out to the sea, because the physiological changes allow the fish to tolerate salt water. |
Genetic architecture of kidney cancer uncovered by research Posted: 29 Oct 2014 05:36 AM PDT An apparent link between exposure to aristolochic acid and incidence of kidney cancer, has been uncovered by researchers conducting a new study on a large cohort of kidney cancer patients in Europe. This study sheds light on the genetic architecture of the disease, and underscores the importance of investigating possible sources of exposure to aristolochic acid. |
