A University of Alberta geomicrobiologist and his PhD student are part of a research team that has identified phosphorus as the mystery ingredient that pushed oxygen levels in the oceans high enough to establish the first animals on Earth 750 million years ago.

URBANA – Finding good child care and being able to engage easily in important interactions with your child care provider are critical to any mother's ability to work outside the home.

"Suppose you're living in the rural Midwest and you don't speak English very well. Can you imagine leaving your child with a child care provider if you couldn't communicate well with that person?" said Angela Wiley, a University of Illinois associate professor of applied family studies.

"The immigrant moms we interviewed for this study faced just this dilemma," she said.

PHILADELPHIA — Researchers have identified two small-molecule inhibitors that effectively targeted the focal adhesion kinase (FAK), an enzyme present in certain cancers that helps tumors thrive and survive.

If the drugs are developed into oral therapeutic agents in the future, they could open up the potential for more effective and less toxic cancer therapies, according to research presented at The American Association for Cancer Research special conference on Colorectal Cancer: Biology to Therapy, held Oct. 27-30, 2010.

Race may not be as important as previously thought in determining who buddies up with whom, suggests a new UCLA–Harvard University study of American college students on the social networking site Facebook.

Millions of Medicare recipients have been forcibly reassigned to different prescription drug plans because Part D reimbursements to insurance companies covering low-income patients are lower than the actual costs incurred, according to a study released online today by Health Affairs. The report describes how a system designed to encourage competition and to subsidize care for low-income Medicare patients instead has led companies to raise their premiums in an effort to price themselves out of the low-income segment of the Part D market.

Ancient gardens are the stuff of legend, from the Garden of Eden to the Hanging Gardens of Babylon. Now researchers at Tel Aviv University, in collaboration with Heidelberg University in Germany, have uncovered an ancient royal garden at the site of Ramat Rachel near Jerusalem, and are leading the first full-scale excavation of this type of archaeological site anywhere in the pre-Hellenistic Levant.

Professor Zhipeng Wu has invented a portable scanner based on radio frequency technology, which is able to show in a second the presence of tumours – malignant and benign – in the breast on a computer.

Using radio frequency or microwave technology for breast cancer detection has been proven by researchers in the US, Canada and UK. However, up to now, it can take a few minutes for an image to be produced, and this had to be done in a hospital or specialist care centre.

Patients with cancer found at the end of the large intestine called the rectum who receive one week of radiation therapy before surgery have a 50 percent reduction in chance that their cancer will return after 10 years, according to a large, randomized study presented at the plenary session, November 1, 2010, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO).

Members of the public could form the backbone of powerful new mobile internet networks by carrying wearable sensors.

According to researchers from Queen's University Belfast, the novel sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.

The engineers from Queen's renowned Institute of Electronics, Communications and Information Technology (ECIT), are working on a new project based on the rapidly developing science of body centric communications.

The equipment, based on automatic camera surveillance and wireless network connection, is handily located on a mobile trailer unit. The police are thus able to monitor traffic and impose penalties for violations more comprehensively and fairly. The monitoring information is gathered into a common database available to the police, road operators and environmental authorities. A pilot system has been launched in Tampere enabling the police to test the equipment.

Cincinnati, OH, October 28, 2010 -- The American Academy of Pediatrics (AAP) recommends that parents limit combined screen time from television, DVDs, computers, and video games to 2 hours per day for preschool-age children. In a study soon to be published in The Journal of Pediatrics, researchers found that many children are exposed to screen time both at home and while at child care, with 66% exceeding the recommended daily amount.

Medical schools and clinics could boost the number of primary care physicians in medically underserved areas by selecting and encouraging students from these communities, who often exhibit a strong sense of responsibility for and identification with the people there, according to a new study by UCLA researchers and colleagues published in the current issue of the American Journal of Public Health.

Extending its 26-year tradition of innovative quantum voltage standards, researchers at the National Institute of Standards and Technology (NIST) have begun shipping a new 10-volt standard to users around the world. The programmable system measures both direct current (DC) and alternating current (AC) voltages.NIST AC/DC 10-volt standard chip.

Better psychological and spiritual support, improved planning of care and stronger relationships with physicians are necessary to improve end-of-life care in Canada, according to a study by a Queen's University professor.

"High quality end-of-life care should be the right of every Canadian," says professor of Medicine and Epidemiology Daren Heyland, who is also a researcher at Kingston General Hospital. "But it's not always happening. We know from international studies that Canada ranks ninth in the world in terms of quality of care provided at the end of life."

Scientists are reporting development of a new approach for dealing with offensive household and other odors — one that doesn't simply mask odors like today's room fresheners, but eliminates them at the source. Their research found that a deodorant made from nanoparticles — hundreds of times smaller than peach fuzz — eliminates odors up to twice as effectively as today's gold standard. A report on these next-generation odor-fighters appears in ACS' Langmuir, a bi-weekly journal.
