Poetry in motion: Gemini Observatory releases image of rare polar ring galaxy Posted: 18 Oct 2012 03:59 PM PDT Polar-ring galaxies are peculiar objects. Astronomers have found only a handful of them, so not much is known about their origins. Most have an early-type spiral system, called a lenticular galaxy, as the central showpiece. But NGC 660, which lies about 40 million light-years distant toward the direction of Pisces the Fishes, is the only polar-ring galaxy known with what is called a late-type lenticular galaxy as its host. All, however, display a ring of stars, dust, and gas that extends tens of thousands of light-years across space along an orbit nearly perpendicular to the main disk.

NASA pursues atom optics to detect the imperceptible Posted: 18 Oct 2012 03:59 PM PDT A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible: gravitational waves or ripples in space-time caused by cataclysmic events including even the Big Bang itself.

The hidden burden of bovine Tuberculosis Posted: 18 Oct 2012 03:59 PM PDT Up to 21 percent of herds clearing restrictions for bovine Tuberculosis (bTB) in Great Britain may be harbouring infection, according to a new study.

Tissue-engineered kidneys: Researchers make important strides Posted: 18 Oct 2012 03:48 PM PDT With a worldwide shortage of kidneys for patients who need kidney transplants, researchers are diligently working to find ways to engineer new kidney tissue from a patient's own cells or another source. They've come a step closer to realizing that goal with a breakthrough described in a new study.

High levels of estradiol, progesterone during pregnancy associated with increased risk for HR-negative breast cancer Posted: 18 Oct 2012 12:19 PM PDT Increased concentrations of the pregnancy hormones estradiol and progesterone were associated with an increased risk for hormone receptor-negative breast cancer diagnosed before age 50, according to the results of a nested case-control study.

Depression, shortened telomeres increase mortality in bladder cancer patients Posted: 18 Oct 2012 11:18 AM PDT Low depressive symptoms and a longer telomere length are compelling factors that contribute to a prolonged life for bladder cancer patients, according to researchers.

Modeling feat sheds light on protein channel's function Posted: 18 Oct 2012 11:18 AM PDT Chemists have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes. The feat required bridging timescales from the realm of nanoseconds all the way up to full minutes, exceeding the scope of earlier simulation efforts by more than six orders of magnitude. The result is a detailed molecular understanding of how the translocon works.

Elevated risk of blood clots in women taking birth control containing drospirenone, study shows Posted: 18 Oct 2012 11:18 AM PDT New research has found an increased risk of arterial thrombotic events and venous thromboembolic events -- commonly referred to as blockage of arteries and blood clots, respectively -- associated with drospirenone-containing birth control pills compared to four low-dose estrogen combined hormonal contraceptives.

Tropical collapse in Early Triassic caused by lethal heat: Extreme temperatures blamed for 'Dead Zone' Posted: 18 Oct 2012 11:18 AM PDT Scientists have discovered why the 'broken world' following the worst extinction of all time lasted so long -- it was simply too hot to survive. The end-Permian mass extinction, which occurred around 250 million years ago in the pre-dinosaur era, wiped out nearly all the world's species. Typically, a mass extinction is followed by a 'dead zone' during which new species are not seen for tens of thousands of years. In this case, the dead zone, during the Early Triassic period which followed, lasted for a perplexingly long period: five million years.

New technique for nanostructure assembly pioneered Posted: 18 Oct 2012 11:18 AM PDT A team of researchers has developed a new technique for growing new materials from nanorods. Materials with enhanced properties engineered from nanostructures have the potential to revolutionize the marketplace in everything from data processing to human medicine. However, attempts to assemble nanoscale objects into sophisticated structures have been largely unsuccessful. This latest study represents a major breakthrough in the field, showing how thermodynamic forces can be used to manipulate growth of nanoparticles into superparticles with unprecedented precision.

Optical vortices on a chip: Integrated arrays of emitters of 'optical vortex beams' on a silicon chip Posted: 18 Oct 2012 11:18 AM PDT Researchers have demonstrated integrated arrays of emitters of 'optical vortex beams' on a silicon chip. Contradicting traditional conception, light in such beams does not propagate in straight rays. Instead, its energy travels in a spiral fashion in a hollow conical beam shape. The beams therefore look very much like a vortex or cyclone, with its light rays 'twisted' either left-handed or right-handed. In theory, there is no limit to how twisted the light rays can be.

Researchers unveil 3-D structure of 'molecular machine' that initiates DNA transcription Posted: 18 Oct 2012 11:18 AM PDT Scientists have determined the three-dimensional structure of the transcription initiation complex, the key intermediate in the process by which cells read out genetic information in DNA. The "molecular machine" responsible for transcription initiation -- a protein complex that consists of the enzyme RNA polymerase and the initiation factor sigma -- recognizes a specific site on DNA preceding a gene, binds to DNA, unwinds the DNA helix, and pre-organizes the unwound DNA to enable subsequent reactions.

'Time-capsule' Japanese lake sediment advances radiocarbon dating for older objects Posted: 18 Oct 2012 11:18 AM PDT A series of radiocarbon measurements from Japan's Lake Suigetsu will give scientists a more accurate benchmark for dating materials, especially for older objects. Researchers extracted cores containing organic material from the bottom of the Japanese lake where it had lain undisturbed for tens of thousands of years. They provide a more precise way to examine radiocarbon ages of organic material for the entire 11,000-53,000-year time range.

No antibodies, no problem: Researchers identify how mosquito immune system attacks specific infections Posted: 18 Oct 2012 10:40 AM PDT Researchers have determined a new mechanism by which the mosquitoes' immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections.

Election 2012: Will voters follow their 'gut feelings' at polls? Posted: 18 Oct 2012 10:39 AM PDT Americans going to the polls generally pull the lever based on one thing: their gut feelings, says a presidential politics expert.

Germs in space: Preventing infection on long flights Posted: 18 Oct 2012 10:09 AM PDT On a long spaceflight unique conditions including microgravity could give microbes the upper hand, but not if astronauts and their spacecrafts are properly prepared.

Mutation that causes skin hyperproliferation identified Posted: 18 Oct 2012 09:33 AM PDT Scientists have identified a mutation in a gene that causes patches of very thick skin to appear on the palms and soles of affected people. This skin disorder is related, albeit in a much milder form, to that of the Indonesian "Tree Man", Dede Koswara.

Ozone affects forest watersheds Posted: 18 Oct 2012 09:33 AM PDT Scientists have found that rising levels of ozone, a greenhouse gas, may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams, and other water bodies. Such effects could potentially reduce water supplies available to support forest ecosystems and people in the southeastern United States.

Genes and immune system shaped by childhood poverty, stress Posted: 18 Oct 2012 09:30 AM PDT New research has revealed that childhood poverty, stress as an adult, and demographics such as age, sex and ethnicity, all leave an imprint on a person's genes. And, that this imprint could play a role in our immune response.

Scientists harness immune system to prevent lymphoma relapse Posted: 18 Oct 2012 09:30 AM PDT Scientists hope that lymphoma patients could benefit from a new drug that triggers the cancer-fighting properties of the body's own immune system, after highly promising early laboratory results.

Rethinking toxic proteins on the cellular level: Lipid droplets play an unexpected role in embryo development Posted: 18 Oct 2012 09:30 AM PDT Histones are proteins needed to assemble DNA molecules into chromosomes. They have long represented a classic balancing act in biology; too few histone molecules result in DNA damage, while too many histones are toxic to the cell. New research is causing a fundamental shift in the concept of histone balance and the mechanism behind it.

Treating vascular disorders with a cell-based strategy Posted: 18 Oct 2012 09:30 AM PDT A new approach for generating large numbers of circulatory system cells, known as vascular endothelial cells (VECs), from human amniotic-fluid-derived cells is reported in a new study. The strategy, which shows promise in mice, opens the door to establishing a vast inventory of VECs for promoting organ regeneration and treating diverse vascular disorders.

From the twitching whiskers of babes: Naptime behavior shapes the brain Posted: 18 Oct 2012 09:30 AM PDT The whiskers of newborn rats twitch as they sleep, in a whisker equivalent of rapid-eye-movements, and that could open the door to new understandings about the intimate connections between brain and body. The discovery reinforces the notion that such involuntary movements are a vital contributor to the development of sensorimotor systems, say researchers.

Avoiding future stock market crashes: 'Diversification effect' that protects portfolio of shares disappears during general slump Posted: 18 Oct 2012 07:30 AM PDT A 72-year study of the Dow Jones could help avoid the kind of stock market crash that struck the world economy in 2008. New research reveals that the 'diversification effect' that protects a portfolio of shares through the vagaries of the stock market disappears when there is a general slump in the market.

Manufacturing complex 3-D metallic structures at nanoscale made possible Posted: 18 Oct 2012 07:30 AM PDT The fabrication of many objects, machines, and devices around us rely on the controlled deformation of metals by industrial processes such as bending, shearing, and stamping. Is this technology transferrable to nanoscale? Can we build similarly complex devices and machines with very small dimensions? Scientists in Finland and the U.S. have just demonstrated this to be possible. By combining ion processing and nanolithography they have managed to create complex three-dimensional structures at nanoscale.

World's largest subwoofer: Earthquakes 'pump' ground to produce infrasound Posted: 18 Oct 2012 07:29 AM PDT Earthquakes sway buildings, buckle terrain, and rumble -- both audibly and in infrasound, frequencies below the threshold of human hearing. New computer modeling by a team of researchers indicates that most of the low-frequency infrasound comes from an unexpected source: the actual "pumping" of Earth's surface. The researchers confirmed their models by studying data from an actual earthquake.

Taking the bite out of baseball bats Posted: 18 Oct 2012 07:29 AM PDT Miss hitting the "sweet spot" on a baseball bat and the resulting vibrations can zing your hands. Bat companies have tried for decades to reduce these painful shocks with limited success. But acoustics researcher Daniel Russell has figured out that bat vibrations between 600 and 700 hertz (Hz) cause the most pain and that specifically tuned vibration absorbers are the best at combating the sting.

Short booms still annoying: How mid-level noise bursts affect concentration of arithmetic-solving test subjects Posted: 18 Oct 2012 07:29 AM PDT Noise can be distracting, especially to a person trying to concentrate on a difficult task. Studying annoying noises helps architects design better building environments and policy makers choose effective noise regulations. To better understand how short noise bursts affect humans' mental state, researchers played quarter-second-long white noise clips to test subjects as they worked on arithmetic problems. The researchers noticed a slight general trend toward lower performance when louder noises were played, and also identified sound level ranges that caused participants to report significant levels of annoyance.

Dinosaur-era acoustics: Global warming may give oceans the 'sound' of the Cretaceous Posted: 18 Oct 2012 07:29 AM PDT Global temperatures directly affect the acidity of the ocean, which in turn changes the acoustical properties of sea water. New research suggests that global warming may give Earth's oceans the same hi-fi sound qualities they had more than 100 million years ago, during the Age of the Dinosaurs.

Helmet-to-helmet collisions: Scientists model how vibrations from football hits wobble the brain Posted: 18 Oct 2012 07:29 AM PDT Hard collisions can lead to player concussions, but the physics of how the impact of a helmet hit transfers to the brain are not well understood. A research team has created a simplified experimental model of the brain and skull inside a helmet during a helmet-to-helmet collision.

Decreased gene activity is likely involved in childhood risk for anxiety and depression Posted: 18 Oct 2012 07:27 AM PDT Decreased activity of a group of genes may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new study.

New drug to target and destroy tumor cells developed: Minnelide gives new hope for treating pancreatic cancer Posted: 18 Oct 2012 07:27 AM PDT Researchers have developed new drug to target tumor cells in pancreatic cancer. The study is based on successful outcomes in a mouse model -- results researchers expect to carry over to human patients when the drug potentially begins human trials in 2013. The drug, Minnelide, is a type of injectable chemotherapy designed to target tumor cells. The drug works by inhibiting a heat shock protein, HSP 70, which has been proven to aid the growth of tumor cells. By stopping HSP 70 from working, Minnelide disperses the cells integral to the tumor's growth and the cancer disintegrates.

Weight loss does not improve fertility, but does improve sexual function, research finds Posted: 18 Oct 2012 07:27 AM PDT Losing weight does not necessarily lead to improved fertility in women, but it can improve sexual function, according to a recent study that followed morbidly obese women of reproductive age for up to two years after Roux en Y gastric bariatric bypass surgery
