The ability to change vocal sounds (vocal plasticity) and develop an accent is potentially far more widespread in mammals than previously believed, according to new research on goats from Queen Mary, University of London. Vocal plasticity is the ability of an individual to modify the sound of their voice according to their social environment. Humans benefit from an extreme form of vocal plasticity which allows us to produce a wide range of sounds and accents, but in most other mammals (except, for example, bats and whales) vocalisations were thought to be genetically ...

The study of more than 11,000 pregnant women, in partnership with Mars Petcare, showed that those who owned dogs were approximately 50% more likely to achieve the recommended 30 minutes of exercise a day through high levels of brisk walking than those without dogs. Scientists suggest that as it is a low-risk exercise, walking a dog could form part of a broader strategy to improve the health of pregnant women. Previous studies have shown that maternal obesity and large weight gain during pregnancy has adverse outcomes for mother and child. Studies show, for example, that ...

CINCINNATI -- As part of the first national, randomized clinical trial to study two methods of drug delivery for seizing patients, researchers have shown that using an auto-injector, similar to an EpiPen, to deliver anticonvulsant medication stops prolonged seizures more quickly and effectively than drug delivery through an IV line. The research, which will be published in the Feb. 16 edition of the New England Journal of Medicine, was conducted as part of the Rapid Anticonvulsant Medication Prior to Arrival Trial (RAMPART), which included University of Cincinnati (UC) ...

VTT Technical Research Centre of Finland, the leading multi-technological applied research organisation in Northern Europe, has developed an optical accessory that turns an ordinary camera phone into a high-resolution microscope. The device is accurate to one hundredth of a millimetre. Among those who will benefit from the device are the printing industry, consumers, the security business, and even health care professionals. A new Finnish enterprise called KeepLoop Oy and VTT are already exploring the commercial potential of the invention. The first industrial applications ...

BOSTON, MA (February 15, 2012) — For decades, researchers have sought a genetic explanation for idiopathic dilated cardiomyopathy (DCM), a weakening and enlargement of the heart that puts an estimated 1.6 million Americans at risk of heart failure each year. Because idiopathic DCM occurs as a familial disorder, researchers have long searched for genetic causes, but for most patients the etiology for their heart disease remained unknown. Now, new work from the lab of Christine Seidman, a Howard Hughes Investigator and the Thomas W. Smith Professor of Medicine and Genetics ...

When a person is experiencing a prolonged convulsive seizure, quick medical intervention is critical. With every passing minute, the seizure becomes harder to stop, and can place the patient at risk of brain damage and death. This is why paramedics are trained to administer anticonvulsive medications as soon as possible -- traditionally giving them intravenously before arriving at the hospital. Now a major clinical trial has shown that an even faster method that involves injecting the drugs into the thigh muscle using an autoinjector (similar to a pre-loaded syringe) ...

Like a stream of air shooting out of an airplane's broken window to relieve cabin pressure, scientists at Scripps Institution of Oceanography at UC San Diego say lava formations in eastern Oregon are the result of an outpouring of magma forced out of a breach in a massive slab of Earth. Their new mechanism explaining how such a large volume of magma was generated is published in the Feb. 16 issue of the journal Nature. For years scientists who study the processes underlying the planet's shifting tectonic plates and how they shape the planet have debated the origins of ...

Astronomers using NASA's Hubble Space Telescope have found a cluster of young, blue stars encircling the first intermediate-mass black hole ever discovered. The presence of the star cluster suggests that the black hole was once at the core of a now-disintegrated dwarf galaxy. The discovery of the black hole and the star cluster has important implications for understanding the evolution of supermassive black holes and galaxies. "For the first time, we have evidence on the environment, and thus the origin, of this middle-weight black hole," said Mathieu Servillat, who worked ...

On the health front, the poor often have at least two things going against them: a lack of insurance and chronic illnesses, of which diabetes is among the most common. The federal Affordable Care Act would expand the capacity of the nation's 8,000 community health centers to provide care for low-income, largely minority patients — from the current 20 million to about 40 million by 2015. The federal government is also trying to ensure that these community health centers deliver high-quality primary care, including diabetes care. A crucial part of this is the implementation ...

Pasadena, CA— Eta Carinae, one of the most massive stars in our Milky Way galaxy, unexpectedly increased in brightness in the 19th century. For ten years in the mid-1800s it was the second-brightest star in the sky. (Now it is not even in the top 100.) The increase in luminosity was so great that it earned the rare title of Great Eruption. New research from a team including Carnegie's Jose Prieto, now at Princeton University, has used a "light echo" technique to demonstrate that this eruption was much different than previously thought. Their work is published Feb. 16 in ...

CORVALLIS, Ore. – Half of the young adult Latino men and women responding to a survey in rural Oregon acknowledge not using regular effective contraception – despite expressing a desire to avoid pregnancy, according to a new Oregon State University study. Researchers say the low rate of contraception among sexually active 18- to 25-year-olds needs to be addressed – and not just among Latino populations. Research has shown many young adults from all backgrounds eschew contraception for many reasons including the mistaken belief that they or their partners cannot get pregnant. "The ...

Faced with the inevitability of death, we all wish for good caregiving during the final stage of our lives. A new study from Karolinska Institutet and Umeå University shows that non-pharmacological caregiving at the end of life in specialized palliative care is not as basic as one might believe but is based on complex professional decisions that weave physical, psychosocial and existential dimensions into a functional whole. The researchers have found that particularly important aspects of palliative care are an aesthetically pleasing, safe and comfortable environment, ...

Scientists at the University of Illinois, USA have discovered a new species of tiny, grasshopper-like insect in the tropical rainforests of the Toledo District in southern Belize. Dr Sam Heads and Dr Steve Taylor co-authored a paper, published in the open access journal ZooKeys, documenting the discovery and naming the new species Ripipteryx mopana. The name commemorates the Mopan people – a Mayan group, native to the region. "Belize is famous for its biodiversity, although very little is known about the insect fauna of the southern part of the country. This is particularly ...

There is an urgent need to increase the number of organ donors from black and minority ethnic (BME) groups in countries with a strong tradition of immigration, such as the UK, USA, Canada and the Netherlands, in order to tackle inequalities in access and waiting times. That is the key finding of a research paper on ethnicity and transplants, published by the Journal of Renal Care in a free online supplement that includes 15 studies on different aspects of diabetes and kidney disease. "BME groups are disproportionately affected by kidney problems for a number of ...

Stress levels of unemployed people are linked more to their surroundings than their age, gender, disposable income, and degree of deprivation, a study shows. The presence of parks and woodland in economically deprived areas may help people cope better with job losses, post traumatic stress disorder, chronic fatigue and anxiety, researchers say. They found that people's stress levels are directly related to the amount of green space in their area – the more green space, the less stressed a person is likely to be. Researchers measured stress by taking saliva samples ...

A drastic switch to low carbon-emitting technologies, such as wind and hydroelectric power, may not yield a reduction in global warming until the latter part of this century, research published today suggests. Furthermore, it states that technologies that offer only modest reductions in greenhouse gases, such as the use of natural gas and perhaps carbon capture and storage, cannot substantially reduce climate risk in the next 100 years. The study, published today, Thursday 16 February, in IOP Publishing's journal Environmental Research Letters, claims that the rapid ...

Scientists at The University of Nottingham have discovered a new molecule that could offer the hope of new treatments for people allergic to the house dust mite. The team of immunologists led by Dr Amir Ghaem-Maghami and Professor Farouk Shakib in the University's School of Molecular Medical Sciences have identified the molecule DC-SIGN which appears to play a role in damping down the body's allergic response to the house dust mite . The molecule can be found on the surface of the immune cells which play a key role in the recognition of a major allergen from house dust ...

Laser light in combination with certain drugs – known as photodynamic therapy – can destroy cancer tumours, but is today used mostly to cure skin cancer. The reason that internal tumours are not treated with the method is that the technology does not exist to check that the precise amount of light is administered. However, software developed by researchers in atomic physics at Lund University in Sweden looks like being able to solve the problem. "I think we are about to see a real breakthrough, both for us and for other research groups around the world who conduct research ...

A study from North Carolina State University shows that Toyota's safety-related recalls that began in 2009 made little to no impact on how consumers perceived the brand. "These findings highlight the importance of establishing and maintaining a reputation for quality," says Dr. Robert Hammond, an assistant professor of economics at NC State and lead author of a paper describing the study. "Not only will it help you sell cars in the first place, but it will help you weather public scrutiny in the event of a recall." Hammond launched the study because he wanted to see ...

Despite new regulations restricting UK TV advertisements for food, children are still exposed to the same level of advertising for junk foods which are high in fat, salt and sugar, researchers have found. Unexpectedly, academics at Newcastle University also found that since the new restrictions were introduced five years ago, viewers of all ages are seeing many more adverts for unhealthy foods. In work funded by National Prevention Research Initiative and published today in PLoS ONE, the team describe how they examined the nutritional content of TV ads 6 months before ...

TORONTO, Ont. -- One of the first things people ask new parents is how much does their baby weigh. For some immigrant parents, especially South Asians, the question may be stressful. Many of their newborns are incorrectly diagnosed as being significantly underweight, meaning they could be at higher risk of developmental issues. Researchers at St. Michael's Hospital say many of these infants are in fact the correct birthweight for their ethnic group and should not be compared to those of babies of Canadian-born mothers. The researchers, led by Dr. Joel Ray, have developed ...
