Converting Human-Generated Waste Into Fuel in Space Posted: 25 Nov 2014 12:46 PM PST |
Endangered species success: Idaho salmon regaining fitness advantage Posted: 25 Nov 2014 11:08 AM PST Once on the brink of extinction with only a few fish remaining, Snake River sockeye salmon are regaining the fitness they need to rebuild wild populations. A new analysis shows that naturally spawned offspring of fish saved by a hatchery program are now surviving to return at increasing rate -- high enough to not only sustain the population but also to rebuild it. |
Mere expectation of treatment can improve brain activity in Parkinson's patients Posted: 25 Nov 2014 11:08 AM PST Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study. "The findings highlight the power of expectations to drive changes in the brain," said a co-author of the study. "The research highlights important links between psychology and medicine." |
Obstructive sleep apnea treatments may reduce depressive symptoms Posted: 25 Nov 2014 11:08 AM PST |

Long-term testosterone therapy does not increase risk of prostate cancer Posted: 25 Nov 2014 09:49 AM PST Testosterone (T) therapy is routinely used in men with hypogonadism, a condition in which diminished function of the gonads occurs. Although there is no evidence that T therapy increases the risk of prostate cancer (PCa), there are still concerns and a paucity of long-term data. In a new study, investigators examined three parallel, prospective, ongoing, cumulative registry studies of over 1,000 men. Their analysis showed that long-term T therapy in hypogonadal men is safe and does not increase the risk of PCa. |
Vegetable oil ingredient key to destroying gastric disease bacteria Posted: 25 Nov 2014 09:48 AM PST The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils. In mice, LipoLLA was safe and more effective against H. pylori infection than standard antibiotic treatments. |
Posted: 25 Nov 2014 09:48 AM PST Scientists predicts that a phenomenon known in physics as Fano resonance can exist in materials that are used in electronic devices. The discovery advances the fundamental understanding of ferroelectric relaxors, which were discovered in the early 1960s but whose properties are still poorly understood. |
Mining can damage fish habitats far downstream, study shows Posted: 25 Nov 2014 08:18 AM PST Anglers across the nation wondering why luck at their favorite fishing spot seems to have dried up may have a surprising culprit: a mine miles away, even in a different state. Scientists have taken a first broad look at the impacts of mines across the country and found that mining can damage fish habitats miles downstream, and even in streams not directly connected to the mines. |
Athletes' testosterone surges not tied to winning, study finds Posted: 25 Nov 2014 08:18 AM PST |
Pathology specialist contributes to debate on breast cancer gene screening Posted: 25 Nov 2014 08:18 AM PST |
E-health records used to search for hidden drug benefits Posted: 25 Nov 2014 08:18 AM PST With research and development costs for many drugs reaching well into the billions, pharmaceutical companies want more than ever to determine whether their drugs already at market have any hidden therapeutic benefits that could warrant putting additional indications on the label and increase production. |
Superbug in SE Michigan shows recent decline Posted: 25 Nov 2014 08:18 AM PST A new study finds a decrease in an emergent strain of methicillin-resistant S. aureus (MRSA) that is resistant to last line defense antibiotics. Researchers examined the prevalence of vancomycin-resistant Staphylococcus aureus (VRSA) infections in southeastern Michigan, where the majority of these infections have occurred in the US. |
Trojan horse tactic gives parasites edge over immune systems Posted: 25 Nov 2014 08:18 AM PST Parasites use Trojan horse subterfuge to suppress the immunity of their victims when causing infection, according to a study. Scientists have shown that parasites are able to secrete tiny sealed packages of genetic material into the cells of their victims, in order to suppress the immune response to infection. |
Blu-ray disc can be used to improve solar cell performance Posted: 25 Nov 2014 08:18 AM PST Who knew about Blu-ray discs? One of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to a new study. Researchers have discovered that the pattern of information written on a Blu-ray disc -- and it doesn't matter if it's Jackie Chan's 'Supercop' or the cartoon 'Family Guy' -- works very well for improving light absorption across the solar spectrum. |
Vultures evolved an extreme gut to cope with disgusting dietary habits Posted: 25 Nov 2014 08:18 AM PST |
Patients at emergency departments regarded as 'symptoms,' researcher says Posted: 25 Nov 2014 08:15 AM PST |
A 'hybrid vehicle' that delivers DNA Posted: 25 Nov 2014 08:15 AM PST A new hybrid vehicle is under development. Its performance isn't measured by the distance it travels, but rather the delivery of its cargo: vaccines that contain genetically engineered DNA to fight HIV, cancer, influenza and other maladies. The technology is a biomedical advancement that could help unleash the potential of DNA vaccines, which despite two decades of research, have yet to make a significant impact in the treatment of major illnesses. |
Pain and itch in a dish: Scientists convert human skin cells into sensory neurons Posted: 25 Nov 2014 07:43 AM PST Scientists have found a simple method to convert human skin cells into the specialized neurons that detect pain, itch, touch and other bodily sensations. These neurons are also affected by spinal cord injury and involved in Friedreich's ataxia, a devastating and currently incurable neurodegenerative disease that largely strikes children. |
Study maps how city neighborhoods affect diabetes risk Posted: 25 Nov 2014 07:21 AM PST Public health researchers in Philadelphia looked at how neighborhood and community-level factors -- not just individual factors like diet, exercise and education -- influence people's diabetes risk. Their new study adds insight into the role of the physical and social environment on diabetes risk, zip code by zip code throughout the city. |
Barriers to public health data-sharing; life-saving solutions Posted: 25 Nov 2014 07:21 AM PST |
Body size requires hormones under control Posted: 25 Nov 2014 07:19 AM PST The proper regulation of body size is of fundamental importance, but the mechanisms that stop growth are still unclear. Scientists have shed new light on how animals regulate body size. The researchers uncovered important clues about the molecular mechanisms triggered by environmental conditions that ultimately affect final body size. They show that the timing of synthesis of a steroid hormone called ecdysone is sensitive to nutrition in the fruit fly and describe the key proteins involved in this regulatory mechanism. This study explains what causes hormones to become environmentally-sensitive and provides important clues on body size regulation. |
Posted: 25 Nov 2014 07:19 AM PST Researchers have shed light on a gene mutation linked to autistic traits. The team already knew that some people with autism were deficient in a gene called neurexin-II. To investigate whether the gene was associated with autism symptoms, the Leeds team studied mice with the same defect. They found behavioral features that were similar to autism symptoms, including a lack of sociability or interest in other mice. |
New plastic that disappears when you want it to Posted: 25 Nov 2014 07:17 AM PST Plastic populates our world through everything from electronics to packaging and vehicles. Once discarded, it resides almost permanently in landfills and oceans. A new discovery holds scientific promise that could lead to a new type of plastic that can be broken down when exposed to a specific type of light and is reduced back to molecules, which could then be used to create new plastic. |
Gene linked to tamoxifen-resistant breast cancers Posted: 25 Nov 2014 07:17 AM PST |
Alzheimer's in a dish model converts skin cells to induced neurons expressing amyloid-beta and tau Posted: 25 Nov 2014 07:17 AM PST |
Circumstances are right for weed invasion to escalate, researchers say Posted: 25 Nov 2014 07:17 AM PST |
How environment contributes to several human diseases Posted: 25 Nov 2014 07:17 AM PST Using a new imaging technique, researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer's disease. |
Researchers Identify Genetic Markers That May Predispose Individuals for Kidney Injury Posted: 25 Nov 2014 07:17 AM PST |
Scientists completed the first orchid whole genome sequencing Posted: 25 Nov 2014 06:54 AM PST As one of the most diverse plant family, orchid now has its first genome sequenced. All around the world, orchids are highly endangered species because of illegal collection and habitat loss. The complete genome sequence of P. equestris will provide an important resource to explore orchid diversity and evolution at the genome level. |
Breakthrough in flexible electronics enabled by inorganic-based laser lift-off Posted: 25 Nov 2014 06:54 AM PST Engineers have developed an easier methodology to make high performance flexible electronics by using the Inorganic-based Laser Lift-off (ILLO), which enables nanoscale processes for high density flexible devices and high temperature processes that were previously difficult to achieve on plastic substrates. |
One-two punch of drugs better than either alone against colorectal cancer Posted: 25 Nov 2014 06:11 AM PST Experimental anti-cancer agents PF-04691502 and PD-0325901 excel in lab tests against colorectal cancer models and enter phase 1 trial, scientists report. "This study demonstrates strong potential for this combination in treating laboratory models of colorectal cancer. We hope that if we can discover biomarkers that predict which tumors respond and which don't respond to the combination that we can optimize its use," one researcher says. |
Sialic acid shields human cells from attack by immune system Posted: 25 Nov 2014 06:11 AM PST Biochemists have identified molecular structures that allow the immune system to tell friend from foe. The researchers identified and crystallized a complex that forms the contact point between the healthy human cell and the complement system. Using nuclear magnetic resonance spectroscopy and X-ray structure analysis, they were able to solve the molecular structure of the complex. It is composed of a glycan containing sialic acid and two domains of the complement system regulator, factor H. |

Asymptomatic atherosclerosis linked to cognitive impairment Posted: 25 Nov 2014 04:48 AM PST In a study of nearly 2,000 adults, researchers found that a buildup of plaque in the body's major arteries was associated with mild cognitive impairment. Atherosclerosis is a condition in which fat, cholesterol and other substances collect in the arteries, forming a substance called plaque that can build up, limiting blood flow. It can occur in any artery of the body, including the carotid, which supplies blood to the brain, coronary arteries and the aorta, which carries oxygenated blood from the heart through the abdomen to the rest of body. |
New device may ease mammography discomfort Posted: 25 Nov 2014 04:48 AM PST |
Homosexuality may help us bond, experts say Posted: 25 Nov 2014 04:47 AM PST Homosexual behavior may have evolved to promote social bonding in humans, according to new research. Researchers found that heterosexual women who have higher levels of progesterone are more likely to be open to the idea of engaging in sexual behaviour with other women. Similarly, when heterosexual men are subtly reminded of the importance of having male friends and allies, they report more positive attitudes toward engaging in sexual behaviour with other men. This pattern is particularly dramatic in men who have high levels of progesterone. |

Problem gambling, personality disorders often go hand in hand Posted: 25 Nov 2014 04:47 AM PST The treatment of people who cannot keep their gambling habits in check is often complicated because they also tend to suffer from personality disorders. Problem gambling creates a multitude of intrapersonal, interpersonal and social difficulties for the roughly 2.3 percent of the population internationally that suffers from this behavior. |
Bitcoin, virtual money: User's identity can be revealed much easier than thought Posted: 25 Nov 2014 04:47 AM PST Bitcoin is the new money: minted and exchanged on the Internet. Faster and cheaper than a bank, the service is attracting attention from all over the world. But a big question remains: are the transactions really anonymous? Several research groups worldwide have shown that it is possible to find out which transactions belong together, even if the client uses different pseudonyms. However it was not clear if it is also possible to reveal the IP address behind each transaction. This has changed: researchers have now demonstrated how this is feasible with only a few computers and about €1500. |
New ways to drain cancer's 'fuel tank' discovered Posted: 25 Nov 2014 04:47 AM PST A potential weakness in cancer's ability to return or become resistant to treatment has been discovered, targeting the 'fuel' part of stem cells which allows tumors to grow. By observing cancer stem cells in a lab setting, researchers discovered that mitochondria are especially important for the proliferative expansion and survival of cancer stem cells, also known as 'tumor initiating cells', which would then promote treatment resistance. |
Better assessment of decision-making capacity Posted: 25 Nov 2014 04:47 AM PST |
Proton pump inhibitors decrease diversity in gut microbiome, increase risk for complications Posted: 25 Nov 2014 04:46 AM PST |
Schistosomas: Tropical parasite uses swim stroke not shared by any other creature Posted: 25 Nov 2014 04:46 AM PST For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Schistosomiasis, are driven by the powerful thrusts of their unique forked tails and chewing enzymes. The parasite's swimming patterns are crucial for its human-seeking chemotactic activity - and are the focus of researchers who ultimately seek to break the chain of infection. |
Fluid dynamics explain what happens when dogs drink water Posted: 25 Nov 2014 04:46 AM PST If you've ever watched a dog drink water, you know that it can be a sloshy, spilly, splashy affair -- in other words, adorable. Behind all of the happy, wet messes, however, lies the mechanical logic of carnivorous compensation -- dogs splash when they drink because they have the cheeks of a predatory quadruped. By studying the drinking habits of various dog breeds and sizes, researchers have recently identified and modeled the fluid dynamics at play when dogs drink water. |

Conserving soil, water in world's driest wheat region Posted: 24 Nov 2014 03:01 PM PST In the world's driest rainfed wheat region, researchers have identified summer fallow management practices that can make all the difference for farmers, water and soil conservation, and air quality. Wheat growers in the Horse Heaven Hills of south-central Washington farm with an average of 6-8 inches of rain a year. Wind erosion has caused blowing dust that exceeded federal air quality standards 20 times in the past 10 years. |
CT scans of coral skeletons reveal ocean acidity increases reef erosion Posted: 24 Nov 2014 03:01 PM PST For coral reefs to persist, rates of reef construction must exceed reef breakdown. Prior research has largely focused on the negative impacts of ocean acidification on reef growth, but new research demonstrates that lower ocean pH also enhances reef breakdown: a double-whammy for coral reefs in a changing climate. |
Boy moms more social in chimpanzees: Watching adult males in action may help youngsters prepare Posted: 24 Nov 2014 03:01 PM PST Four decades of chimpanzee observations reveals the mothers of sons are 25 percent more social than the mothers of daughters, spending about two hours more per day with other chimpanzees than the girl moms did. Researchers believe mothers are giving young males the opportunity to observe males in social situations to help them develop the social skills they'll need to thrive in adult male competition. |
'Dramatic' early phase 1 results for AG-120 in IDH1 mutated AML Posted: 24 Nov 2014 03:00 PM PST |
Posted: 24 Nov 2014 01:29 PM PST Scientists laid out a new framework based on in situ observations that will allow them to describe and understand how phytoplankton assimilate limited concentrations of phosphorus, a key nutrient, in the ocean in ways that better reflect what is actually occurring in the marine environment. This is important because nutrient uptake is a property of ocean biogeochemistry, and in many regions controls carbon dioxide fixation, which ultimately can play a role in mitigating climate change. |
How does the brain react to virtual reality? Completely different pattern of activity in brain Posted: 24 Nov 2014 01:29 PM PST Neurophysicists studying a key brain region where Alzheimer's disease begins have discovered how the brain processes virtual reality. 'The pattern of activity in a brain region involved in spatial learning in the virtual world is completely different than in the real world,' said the professor of physics, neurology, and neurobiology. |
