Sweetpotato weevils differentially attracted to certain colors Posted: 03 Jan 2014 05:56 AM PST New research shows that sweetpotato weevils are attracted to different colors, depending on whether they are indoors or outdoors.

How 'slippers' can end mascara irritation Posted: 03 Jan 2014 05:56 AM PST An end to mascara testing on animals could be in sight thanks to tiny organisms nicknamed "slipper" and "eyelash."

Scientists make advance in cancer research Posted: 03 Jan 2014 05:53 AM PST A protein that has been at the center of cancer drug design for the last 20 years should not be overlooked according to new research.

Alternative to yogurt Posted: 03 Jan 2014 05:53 AM PST Researchers have obtained new products fermented with probiotic bacteria from grains and nuts - what is known as plant-based or vegetable "milks" - which are an alternative to conventional yogurts. The products are specially designed for people with allergies to cow's milk, lactose or gluten intolerance, as well as children and pregnant women.

Nordic study: few persons with metabolic syndrome adhere to nutrition recommendations Posted: 03 Jan 2014 05:53 AM PST Adherence to dietary recommendations is weak among people suffering from metabolic syndrome or having increased risk for metabolic syndrome, according to the Nordic SYSDIET study. In most cases, the diet is too high in salt and saturated fat, and too low in dietary fibre and unsaturated fat; many don't have enough vitamin D. Metabolic syndrome is becoming increasingly widespread, and is associated increased risk of diabetes and cardiovascular diseases. Adherence to dietary recommendations is of vital importance for those belonging to this risk group.

Higher vitamin D levels in pregnancy could help babies become stronger Posted: 03 Jan 2014 05:52 AM PST Children are likely to have stronger muscles if their mothers had a higher level of vitamin D in their body during pregnancy, according to new research. Low vitamin D status has been linked to reduced muscle strength in adults and children, but little is known about how variation in a mother's status during pregnancy affects her child.

Knut the polar bear's medical legacy Posted: 03 Jan 2014 05:52 AM PST Keeping wild animals is an important component of the mission of zoos to educate the public and preserve endangered species. When animals die, tracking the potential cause becomes an investigation of pathogens from around the world. This is because zoo animals are not only potentially exposed to pathogens occurring where the zoo is located, but also to those pathogens harbored by other zoo animals. In other words: the diagnostic challenge is enormous.

Odors expressible in language, as long as you speak right language Posted: 03 Jan 2014 05:52 AM PST It is widely believed that people are bad at naming odours. This has led researchers to suggest smell representations are simply not accessible to the language centers of the brain. But is this really so? New evidence for smell language has been found in the Malay Peninsula.

Dogs sense small variations in Earth's magnetic field, new research suggests Posted: 03 Jan 2014 05:52 AM PST Researchers analyzed the body orientation of 70 dogs of different breeds, while the dogs relieved themselves in the open country and without being on the leash. The statistical analysis of the more than 7,000 observations was initially frustrating. But then the researchers made a striking discovery.

25 years of DNA on computers Posted: 03 Jan 2014 05:52 AM PST DNA carries out its activities "diluted" in the cell nucleus. In this state, it synthesizes proteins and, even though it looks like a messy tangle of thread, in actual fact its structure is governed by precise rules that are important for it to carry out its functions. Biologists have studied DNA by observing it experimentally with a variety of techniques, which have only recently been supplemented by research in silico, that is to say, the study of DNA by means of computer simulations.

Fear of childbirth predicts postpartum depression Posted: 03 Jan 2014 05:52 AM PST Expectant women with prenatally diagnosed fear of childbirth are at an increased risk of postpartum depression, according to a study of over 500,000 mothers in Finland. Women with a history of depression are at the highest risk of postpartum depression. The fact that fear of childbirth puts women without a history of depression at an approximately three times higher risk of postpartum depression is a new observation which may help health care professionals in recognising postpartum depression.

Shingles linked to increased risk of stroke in young adults Posted: 02 Jan 2014 01:56 PM PST Having shingles may increase the risk of having a stroke years later, according to research.

More funding for community health centers improves access to care Posted: 02 Jan 2014 12:23 PM PST Increased federal funding for community health centers has helped low-income adults get access to primary and dental care, according to a new study.

Doctors experienced with using EHRs say they add value for patients Posted: 02 Jan 2014 12:23 PM PST A majority of surveyed physicians said they were alerted to a potential medication error or critical lab value by an electronic health record, finds a new study.

Genetically identical bacteria can behave in radically different ways Posted: 02 Jan 2014 11:20 AM PST When a bacterial cell divides into two daughter cells there can be an uneven distribution of certain survival mechanisms. The resulting cells can behave differently from each other, depending on which parts they received in the split. This is another way that cells within a population can diversify and enhance the odds that some members of a population of bacteria can avoid threats, such as antibiotics.

Animal cells can communicate by reaching out, touching, study shows Posted: 02 Jan 2014 11:20 AM PST In a finding that directly contradicts the standard biological model of animal cell communication, scientists have discovered that typical cells in animals have the ability to transmit and receive biological signals by making physical contact with each other, even at long distance.

Molecule discovered that protects brain from cannabis intoxication Posted: 02 Jan 2014 11:20 AM PST Two INSERM research teams recently discovered that pregnenolone, a molecule produced by the brain, acts as a natural defense mechanism against the harmful effects of cannabis in animals. Pregnenolone prevents THC, the main active principle in cannabis, from fully activating its brain receptor, the CB1 receptor, that when overstimulated by THC causes the intoxicating effects of cannabis. By identifying this mechanism, the INSERM teams are already developing new approaches for the treatment of cannabis addiction.

Study: Having Medicaid increases emergency room visits Posted: 02 Jan 2014 11:20 AM PST Adults who are covered by Medicaid use emergency rooms 40 percent more than those in similar circumstances who do not have health insurance, according to a unique new study that sheds empirical light on the inner workings of health care in the US.

Call for better social science research transparency Posted: 02 Jan 2014 11:20 AM PST A group of social scientists from across the United States say it is time for more stringent and transparent standards in social science research to improve the work's substance, impact and credibility.

New MRI technique illuminates wrist in motion Posted: 02 Jan 2014 10:36 AM PST Radiologists, medical physicists and orthopaedic surgeons have found a way to create "movies" of the wrist in motion using a series of brief magnetic resonance imaging scans.

New cell mechanism discovery key to stopping breast cancer metastasis Posted: 02 Jan 2014 10:36 AM PST Researchers have discovered a cellular mechanism that drives the spread of breast cancer to other parts of the body (metastasis), as well as a therapy which blocks that mechanism.

Atlas Mountains in Morocco buoyed up by superhot rock, study finds Posted: 02 Jan 2014 10:36 AM PST The Atlas Mountains defy the standard model for mountain structure in which high topography must have deep roots for support, according to a new study from Earth scientists.

Roses are red: Why some petunias are blue Posted: 02 Jan 2014 10:32 AM PST Researchers have uncovered the secret recipe to making some petunias such a rare shade of blue. The findings may help to explain and manipulate the color of other ornamental flowers, not to mention the taste of fruits and wine, say researchers. From the flowers' point of view, the findings also have important implications, since blue petals instead of red might spell disaster when it comes to attracting pollinators.

Longmanshen fault zone still hazardous, suggest new reports Posted: 02 Jan 2014 10:32 AM PST The 60-kilometer segment of the fault northeast of the 2013 Lushan rupture is the place in the region to watch for the next major earthquake, according to research. Recent research papers suggest the 2008 Wenchuan earthquake triggered the magnitude 6.6 Lushan quake.

Earthquake lights linked to rift environments, subvertical faults Posted: 02 Jan 2014 10:32 AM PST Rare earthquake lights are more likely to occur on or near rift environments, where subvertical faults allow stress-induced electrical currents to flow rapidly to the surface, according to a new study.

The mouse that ROR’ed Posted: 02 Jan 2014 10:30 AM PST Researchers report that an oncogene dubbed ROR1, found on chronic lymphocytic leukemia (CLL) B cells but not normal adult tissues, acts as an accelerant when combined with another oncogene, resulting in a faster-developing, more aggressive form of CLL in mice.

Solution found to problem limiting development of human stem cell therapies Posted: 02 Jan 2014 10:30 AM PST Biologists have discovered an effective strategy that could prevent the human immune system from rejecting the grafts derived from human embryonic stem cells, a major problem now limiting the development of human stem cell therapies. Their discovery may also provide scientists with a better understanding of how tumors evade the human immune system when they spread throughout the body.

Study finds patients give 'broad endorsement' to stem cell research Posted: 02 Jan 2014 10:30 AM PST In an early indication of lay opinions on research with induced pluripotent stem cells (iPSCs), a new study by bioethicists indicates that despite some ethical concerns, patients give the research "broad endorsement".

More evidence suggests type 2 diabetes is inflammatory disease Posted: 02 Jan 2014 09:34 AM PST As people's waistlines increase, so does the incidence of type 2 diabetes. Now scientists have a better understanding of exactly what happens in the body that leads up to type 2 diabetes, and what likely causes some of the complications related to the disease. Specifically, scientists have found that in mice, macrophages, a specific type of immune cell, invade the diabetic pancreatic tissue during the early stages of the disease.

Berst ways to get seed money through crowdfunding Posted: 02 Jan 2014 08:31 AM PST Early on in our careers, many of us were tutored as to how to best write an effective and attention-getting curriculum vitae in looking for a job. But in today's world, many are looking not for just a job, but are engaged in wide, often Internet-based searches for seed money to launch entrepreneurial ventures of one sort of another. But what guidelines exist as to the best way to go about securing this kind of funding?

Scientists explain age-related obesity: Brown fat fails Posted: 02 Jan 2014 08:23 AM PST As most people resolve themselves to lose weight this New Year, here's why it seems to get easier and easier to pack on unwanted pounds: New research shows that as we age, the thermogenic activity of brown fat is reduced. Brown fat is a "good" fat located in the backs of our necks that helps burn "bad" white fat around our bellies.

Fishing; More protection for big ones Posted: 02 Jan 2014 08:22 AM PST Many popular measures to combat overfishing help conserve mostly small juvenile fish. The results from a set of international studies may now revolutionize fishing regulations.

Minimally invasive aortic valve replacement advantageous for some very elderly patients Posted: 02 Jan 2014 08:20 AM PST Transcatheter aortic valve implantation (TAVI) appears to be an effective alternative to surgical aortic valve replacement (AVR) for the treatment of aortic stenosis in very elderly patients, including those age 85 years and older

Decreasing need for blood transfusion during aortic valve replacement can help reduce complications, costs Posted: 02 Jan 2014 08:20 AM PST Incorporating a blood conservation strategy (BCS) during aortic valve replacement (AVR) can reduce the likelihood of transfusion-related complications, as well as reduce blood-product utilization.

High blood pressure potentially more dangerous for women than men Posted: 02 Jan 2014 08:20 AM PST Doctors may need to treat high blood pressure in women earlier and more aggressively than they do in men, according to scientists.

When being called 'incredibly good' is bad for children Posted: 02 Jan 2014 08:20 AM PST Parents and other adults heap the highest praise on children who are most likely to be hurt by the compliments, a new study finds.

Pennies vs. Pounds: How 'supersizing' could actually lead to healthier choices Posted: 02 Jan 2014 08:20 AM PST New research has found that consumers may be just as willing to buy healthy food if they feel they're still getting a "supersize" deal.
