What 'fecal prints' of microbes can tell us about Earth's evolution Posted: 23 Dec 2014 10:28 AM PST The distinctive "fecal prints" of microbes potentially provide a record of how Earth and life have co-evolved over the past 3.5 billion years as the planet's temperature, oxygen levels, and greenhouse gases have changed. But, despite more than 60 years of study, it has proved difficult, until now, to "read" much of the information contained in this record. |
Could playing Tchaikovsky's 'Nutcracker' and other music improve kids' brains? Posted: 23 Dec 2014 10:25 AM PST In a study called 'the largest investigation of the association between playing a musical instrument and brain development,' a child psychiatry team has found that musical training might also help kids focus their attention, control their emotions and diminish their anxiety. |
'July effect' does not impact stroke outcomes, according to new study Posted: 23 Dec 2014 10:25 AM PST Patients with strokes caused by blood clots -known as acute ischemic strokes- who were admitted in July had similar outcomes compared to patients admitted any other month, according to a new study. The findings challenge concerns about the possibility of lower quality of care and the potential risk of poorer outcomes in teaching hospitals when new medical residents start each July - sometimes called the 'July effect.' |
Echolocation acts as substitute sense for blind people Posted: 23 Dec 2014 10:25 AM PST Human echolocation operates as a viable 'sense,' working in tandem with other senses to deliver information to people with visual impairment, according to new research. Ironically, the proof for the vision-like qualities of echolocation came from blind echolocators wrongly judging how heavy objects of different sizes felt. |
Genetic study sheds light on how mosquitoes transmit malaria Posted: 23 Dec 2014 10:25 AM PST The genetic sequencing of 16 mosquitoes (Anopheles genus) -- the sole carriers of human malaria -- has been determined by an international team of researchers, providing new insight into how they adapt to humans as primary hosts of the disease. |
Overweight teens lose weight for the right reasons, study shows Posted: 23 Dec 2014 09:22 AM PST A new study looked at formerly obese or overweight teens who had lost weight and kept it off. Their motives were more intrinisic, such as being healthy and feeling good. Parents can help by being supportive during major life transitions, the researchers say. |
Way to control internal clocks discovered Posted: 23 Dec 2014 09:22 AM PST Researchers hypothesize that targeting components of the mammalian clock with small molecules like REV-ERB drugs may lead to new treatments for sleep disorders and anxiety disorders. It also is possible that REV-ERB drugs may be leveraged to help in the treatment of addiction. |
Molecular mechanism behind health benefits of dietary restriction identified Posted: 23 Dec 2014 09:22 AM PST A key molecular mechanism behind the health benefits of dietary restriction has been identified by researchers. Also known as calorie restriction, dietary restriction is best known for its ability to slow aging in laboratory animals. The findings here show that restricting two amino acids, methionine and cysteine, results in increased hydrogen sulfide (H2S) production and protection against ischemia reperfusion injury, damage to tissue that occurs following the interruption of blood flow as during organ transplantation and stroke. |
That smartphone is giving your thumbs superpowers Posted: 23 Dec 2014 09:22 AM PST When people spend time interacting with their smartphones via touchscreen, it actually changes the way their thumbs and brains work together, according to a new report. More touchscreen use in the recent past translates directly into greater brain activity when the thumbs and other fingertips are touched, the study shows. |
Dirty pool: Soil's large carbon stores could be freed by increased CO2, plant growth Posted: 23 Dec 2014 08:42 AM PST An increase in human-made carbon dioxide in the atmosphere could initiate a chain reaction between plants and microorganisms that would unsettle one of the largest carbon reservoirs on the planet -- soil. Researchers developed the first computer model to show at a global scale the complex interaction between carbon, plants and soil. |
Mechanics of cells' long-range communication modeled by researchers Posted: 23 Dec 2014 08:42 AM PST Interdisciplinary research is showing how cells interact over long distances within fibrous tissue, like that associated with many diseases of the liver, lungs and other organs. By developing mathematical models of how the collagen matrix that connects cells in tissue stiffens, the researchers are providing insights into the pathology of fibrosis, cirrhosis of the liver and certain cancers. |
Store remodelling benefits bottom line Posted: 23 Dec 2014 08:42 AM PST Retail sales increase by nearly 50 per cent when shops are upgraded, according to new research. "The in-store experience continues to have high relevance; retailers must keep their appearance modern, fresh and in line with that of competitors," said one researcher. "The look, feel, and mood of a firm's retail or service environment are unique and crafted purposefully to contribute to the brand and ultimately, its profitability." |
How electrons split: New evidence of exotic behaviors Posted: 23 Dec 2014 08:42 AM PST Electrons split into electrical charge and magnetic moment in a two-dimensional model, a study has shown for the first time. The discovery marks a new understanding in the discovery of exotic materials such as high-temperature superconductors. |
Strong neighborhood ties can help reduce gun violence Posted: 23 Dec 2014 08:42 AM PST The bonds that tie a neighborhood together can help shield community members from gun violence, according to new findings. "Violence results in chronic community-level trauma and stress, and undermines health, capacity, and productivity in these neighborhoods," said the study's lead author. "Police and government response to the problem has focused on the victim or the criminal. Our study focuses on empowering communities to combat the effects of living with chronic and persistent gun violence." |
Greater risk of premature deaths in neighborhoods with high concentrations of check-cashing places Posted: 23 Dec 2014 08:42 AM PST A new research paper suggests a relation between the density of both check-cashing places and alcohol outlets in a given neighborhood and the risk of premature death in people ages 20-59 years. The findings suggest that the strategic placement of check-cashing places and alcohol outlets in certain areas may provide local residents with ready access to quick cash and-or the purchase of alcohol. |
Bacteria could be rich source for making terpenes Posted: 23 Dec 2014 08:40 AM PST Bacteria could be a rich source of terpenes, the natural compounds common in plants and fungi that are used to make drugs, food additives, perfumes, and other products, a new study suggests. The work also suggests that there may be many new terpene products as yet undiscovered hiding in the genomes of bacteria. |
Armed virus shows promise as treatment for pancreatic cancer Posted: 23 Dec 2014 08:40 AM PST A new combination of two different approaches -- virotherapy and immunotherapy -- is showing 'great promise' as a treatment for pancreatic cancer, according to new research. The study investigated whether the effectiveness of the Vaccinia oncolytic virus -- a virus modified to selectively infect and kill cancer cells -- as a treatment for pancreatic cancer, would be improved by arming it with a gene which modulates the body's immune system. |
Buffer zone guidelines may be inadequate to protect produce from feedlot contamination Posted: 23 Dec 2014 08:40 AM PST The pathogen Escherichia coli O157:H7 can spread, likely airborne, more than one tenth mile downwind from a cattle feedlot onto nearby produce, according to a new paper. "The high percentages of leafy greens contaminated with E. coli suggest great risk for planting fresh produce 180 m [590 feet] or less from a feedlot," the investigators write. |

Researchers have teamed up to stop this mercury where it starts. |
Hunt for Big Bang particles offering clues to the origin of the universe Posted: 23 Dec 2014 08:38 AM PST Billions upon billions of neutrinos speed harmlessly through everyone's body every moment of the day, according to cosmologists. The bulk of these subatomic particles are believed to come straight from the Big Bang, rather than from the sun or other sources. Experimental confirmation of this belief could yield seminal insights into the early universe and the physics of neutrinos. But how do you interrogate something so elusive that it could zip through a barrier of iron a light-year thick as if it were empty space? |
The business-minded veterinarian Posted: 23 Dec 2014 08:38 AM PST The interaction between animals and humans secures the continuous demand for practicing veterinarians, and the fewer veterinarians we have, the larger potential for catastrophic disease. But, newly practicing veterinarians are facing financial struggles today, due to high student loan debt and low starting salaries. Additionally, experts say some rural areas are in need of veterinarians but do not have enough animals to financially support a full-veterinarian for that particular area. |

Trial confirms Ebola vaccine candidate safe, equally immunogenic in Africa Posted: 23 Dec 2014 05:40 AM PST Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa. |
Weight training appears key to controlling belly fat Posted: 23 Dec 2014 05:39 AM PST Healthy men who did 20 minutes of daily weight training had less of an increase in age-related abdominal fat compared with men who spent the same amount of time doing aerobic activities, according to a new study. Combining weight training and aerobic activity led to the most optimal results. Aerobic exercise by itself was associated with less weight gain compared with weight training. |
Genes show the way to better treatment of hepatitis A Posted: 23 Dec 2014 05:39 AM PST One of the most common causes of hepatitis A (formerly known as infectious hepatitis) is a hepatitis C virus infection in the liver. The disease can be treated medically, but not all patients are cured by the treatment currently available. New research shows that the response to medical treatment depends on genetic factors. |
Using laparoscopy for ventriculoperitoneal shunt placement Posted: 23 Dec 2014 05:39 AM PST Researchers conducted a prospective randomized controlled clinical trial to compare a laparoscopic procedure with a mini-laparotomy for insertion of a peritoneal catheter during ventriculoperitoneal shunt surgery. The deciding factor was the rate of shunt malfunction. Although overall shunt failure rates did not differ substantially between patients in the two surgery groups, the authors identified a significant reduction in the rate of distal shunt failure in patients in whom laparoscopy was used. |
Newly discovered assassin bug was incognito, but now it's incognita Posted: 23 Dec 2014 05:39 AM PST A North American assassin bug that has remained hidden for over 100 years has been determined to be a new species. The new bug, Sinea incognita, is described in a new article. |
