Canadian researchers have found that when noise machines are used on a regular basis, they can produce sound levels that can be dangerous for infants' ears, which may lead to hearing, speech or learning problems. "I'm not saying that these devices will cause hearing loss — I'm just saying that they could," said Dr. Blake Papsin, a study author and otolaryngologist-in-chief at The Hospital for Sick Children in Toronto. However, by using infant sound machines, "people are taking a noisy environment and adding more noise to it, without even thinking about the amount," Papsin told LiveScience.

Now, researchers at MIT, in Cambridge, Mass., and the Université Pierre-et-Marie-Curie (UPMC), in Paris, are teasing out the physics of curly hair. "Our work doesn't deal with the collisions of all the hairs on a head, which is a very important effect for animators to control a hairstyle," study co-author Pedro Reis, an assistant professor in MIT's department of civil and environmental engineering, said in a statement. The researchers combined their lab demonstrations with computer simulations to identify several key parameters of curly hair: curvature (as a ratio of curvature to length) and weight (as a ratio of weight to stiffness).

Surveying 1,759 parents, researchers found that while they were able to teach parents that the vaccine and autism were not linked, parents who were surveyed who had initial reservations about vaccines said they were actually less likely to vaccinate their children after hearing the researchers messages. "The first message of our study is that the messaging we use to promote childhood vaccines may not be effective, and in some cases may be counterproductive," said Brendan Nyhan, an assistant professor in the department of government at Dartmouth College, who researches misconceptions about health care. "We need more evidence-based messaging about vaccines.

And the trackers out there aren't an ideal fit for the needs of children and their families, other experts say. But there are some reasons to think trackers could be effective in children.

The scientists have been studying one woman's response to HIV infection from stored samples of her blood and isolated the antibodies that she developed, said Lynn Morris, head of the virology unit at the NICD. The study, by a consortium of scientists from the NICD, local universities and the U.S. Vaccine Research Centre of the National Institute of Allergy and Infectious Diseases, was published in the journal Nature. Humans respond to HIV by producing antibodies to fight the virus.

| 5 Weird Facts About the Oscars The 86th annual Academy Awards are this Sunday, March 2. Ellen DeGeneres will host, stars will schmooze, and large portions of America will tune it to see who wore it best. But whether or not this year's Oscars hold any surprises, the awards ceremony has a strange history. The first person ever presented with an Academy Award was Emil Jannings, a silent-film actor who took the Best Actor award for two films. Read More » | ||||

| Barely There? Chinese Company Debuts World's Thinnest Condom A Chinese company has created the world's thinnest latex condom, snagging the Guinness World Record for the barely-there rubber. The ultra-thin condom was manufactured by Guangzhou Daming United Rubber Products, a China-based company that produces roughly 200 million condoms annually. Currently, the Aoni is available only in Asia, but Victor Chan, who led the project, is eventually hoping to introduce the product to North American markets. "It was quite tricky," Chan told The Province.

This was our first surprise," study author Yukari Takeuchi, of the University of Tokyo, said in a statement. Researchers knew for a long time that in sheep and goats, the males somehow stimulated the release of reproductive hormones in females, but now the new study has identified the actual compound at work, said John J. McGlone, a Texas Tech University professor, who was not involved in the study. "When there is a pheromone in one species, what we are learning is that it often has effects on other species."

Since an exceptionally warm 1998, there has been "a short-term slowdown in the warming of Earth's surface," Britain's Royal Society and the U.S. National Academy of Sciences said in a report. But, they said, that "does not invalidate our understanding of long-term changes in global temperature arising from human-induced changes in greenhouse gases." The warming slowdown has emboldened those who question the evidence about climate change and ask whether a shift in investments towards renewable energies such as wind and solar power, advocated by many experts, is really needed. A build-up of greenhouse gases from human activities, mainly the burning of fossil fuels, is warming the atmosphere and the oceans, raising sea levels and melting Arctic ice, the report said, supporting the long-held view of a U.N. panel of climate scientists.

Today (Feb. 27), the Food and Drug Administration announced plans to update nutrition labels to better reflect the latest nutrition science, and the growing understanding of the link between diet and chronic diseases, the agency said. The proposal comes as a growing number of Americans say they read nutrition labels. About 54 percent of U.S. consumers said they read these labels "often" in 2008, up from 44 percent in 2002, according to FDA statistics.

Harvard Researcher Says You May Doing It Wrong A recent study co-authored by Harvard University doctoral student Silvia Bellezza, suggested that people who go out on a limb with their clothing selections at work or in job interviews have the potential to appear more successful. Business News Daily recently reported on Bellezza's findings. Resistance to conformity pressures can take distinct forms across individuals. Of particular relevance to our work is Tian, Bearden and Hunter's (2001) conceptualization, which suggests that people exhibit three main behavioral manifestations of nonconformity.

In a recent Swiss study, researchers discovered that more bacteria cover a stethoscope's diaphragm (the part that's held against a patient's body) than all regions of a physician's hands, except the fingertips. There are no official guidelines that tell doctors how often they should clean their stethoscopes, the researchers said. "The more you have bacteria on the fingertips, the more you find bacteria on the membrane of the stethoscope," said study author Dr. Didier Pittet, director of infection control at the University of Geneva Hospitals.

Researchers found that blocking a type of genetic material called micro-RNA lowered the inflammation in mice that were grafted with skin from people with psoriasis. Psoriasis is an autoimmune disease (in which the immune system attacks the body's own tissues), and is one of the most common skin conditions worldwide, affecting about 3 percent of the human population. According to the National Psoriasis Foundation, the condition affects about 7.5 million Americans, including celebrities such as Kim Kardashian and country singer LeAnn Rimes.
