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 ...

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 ...

Children with autism often have problems developing motor skills, such as running, throwing a ball or even learning how to write. But scientists have not known whether those difficulties run in families or are linked to autism. New research at Washington University School of Medicine in St. Louis points to autism as the culprit. Their findings were reported in the journal Autism. "From our results, it looks like motor impairments may be part of the autism diagnosis, rather than a trait genetically carried in the family," says lead author Claudia List Hilton, PhD, assistant ...

Groundwater in aquifers on the East Coast and in the Central U.S. has the highest risk of contamination from radium, a naturally occurring radioactive element and known carcinogen. According to a study conducted by the USGS, radium was detected in concentrations that equaled or exceeded U.S. Environmental Protection Agency drinking water standards in more than one in five wells tested in the Mid-Continent and Ozark Plateau Cambro-Ordovician aquifer systems, underlying parts of Ark., Ill., Ind., Iowa, Mich., Minn., Mo, and Wis.; and the North Atlantic Coastal Plain aquifer ...

COLUMBUS, Ohio -- According to a new study, smoking causes the body to turn against its own helpful bacteria, leaving smokers more vulnerable to disease. Despite the daily disturbance of brushing and flossing, the mouth of a healthy person contains a stable ecosystem of healthy bacteria. New research shows that the mouth of a smoker is a much more chaotic, diverse ecosystem—and is much more susceptible to invasion by harmful bacteria. As a group, smokers suffer from higher rates of oral diseases -- especially gum disease -- than do nonsmokers, which is a challenge ...

WASHINGTON -- Scientists and engineers at the National Nuclear Security Administration's (NNSA) three national security laboratories appear committed to their work and core mission of maintaining the country's nuclear weapons stockpile, but according to a new National Research Council report, a "broken relationship" between NNSA and the labs threatens to erode the quality of the scientific research and engineering being conducted there. The committee that wrote the report said that an intrusive degree of oversight stemming from past security and safety concerns at one ...

Children may be receiving the highest exposure to nanoparticles of titanium dioxide in candy, which they eat in amounts much larger than adults, according to a new study. Published in ACS' journal, Environmental Science & Technology, it provides the first broadly based information on amounts of the nanomaterial – a source of concern with regard to its potential health and environmental effects – in a wide range of consumer goods. In the study, Paul Westerhoff, Ph.D., and colleagues point out that titanium dioxide is a common additive to many consumer products, from food ...

When patients receive dental treatment their first reaction is to tell friends and family of their experience. For that reason, Dr. Khoury, Milpitas dentist, invites patients to not only share their positive experiences with their friends and family, but to also share it with other patients by leaving reviews of Montague Dental Excellence online. The patient reviews allow Drs. Khoury and Kolnes, dentists in Milpitas, to not only improve upon the office's practices, but it also encourages new patients to make appointments at Montague Dental Excellence knowing their next ...

Astronomers know how massive stars collapse to form small black holes a few times the mass of the Sun. However, it is not clear how supermassive black holes, which can have masses of millions or even billions of times the Sun's, form in the cores of galaxies. One idea is that supermassive black holes may build up through the merger of small and mid-sized black holes, a view supported by a new study using Hubble. Sean Farrell of the Sydney Institute for Astronomy in Australia and the University of Leicester, UK, discovered a middleweight black hole in 2009 using the European ...

ANN ARBOR, Mich. -- As the Diagnostic and Statistical Manual of Mental Disorders is revised for the first time since 1994, controversy about psychiatric diagnosis is reaching a fever pitch. Suggested changes to the definitions of autism spectrum disorders and depression, among others, are eliciting great concerns. However, there are larger concerns about the DSM as a whole. "Almost no one likes the DSM, but no one knows what to do about it," said University of Michigan psychiatrist Randolph Nesse. The current round of revisions is the fifth since the DSM was originally ...

DENVER - As oncologists already know and newly diagnosed lung cancer patients learn, the kind of treatment given to patients is increasingly becoming dependent on the specific gene mutation present in the cancer. But, as lung cancer moves from being one common disease to multiple different diseases at the molecular level, learning about and getting access to the right treatment within clinical trials can be challenging for these subpopulations of patients that may be widely dispersed around the globe. Dr. Howard (Jack) West, medical director of the Thoracic Oncology Program ...
