Revealing China's ancient past

Revealing China's ancient past

An archeologist at Washington University in St. Louis is helping to reveal for the first time a snapshot of rural life in China during the Han Dynasty.

The rural farming village of Sanyangzhuang was flooded by silt-heavy water from the Yellow River around 2,000 year ago.

New criteria proposed for diagnosing fibromyalgia

The American College of Rheumatology (ACR) is proposing a new set of diagnostic criteria for fibromyalgia that includes common symptoms such as fatigue, sleep disturbances, and cognitive problems, as well as pain. The new criteria are published in the May issue of the ACR journal Arthritis Care & Research.

Research on self-healing concrete yields cost-effective system to extend life of structures

Efforts to extend the life of structures and reduce repair costs have led engineers to develop "smart materials" that have self-healing properties, but many of these new materials are difficult to commercialize. A new self-healing concrete developed and tested by a graduate student at the University of Rhode Island, however, may prove to be cost-effective.

Scientists to study impact of gulf oil spill on marine food webs

New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. But how will these communities be affected over time? Scientists currently know very little about how long it takes for the hydrocarbons and heavy metals in crude oil to work their way through marine food webs.

Nile delta natural gas potential is significant

An estimated 223 trillion cubic feet (tcf) (mean estimate) of undiscovered, technically recoverable natural gas are in the Nile Delta Basin Province, located in the Eastern Mediterranean region.

Undiscovered, technically recoverable resources are those that have yet to be discovered, but if found, could be produced using currently available technology and industry practices.

Precise trace gas analysis, without the noise

Precise trace gas analysis, without the noise

RICHLAND, Washington – Analyzing trace atmospheric gases can now be considerably more precise with the help of a device that delivers stable and reliable power to the lasers used in gas sensors.

Rice University bioengineering students really get their teeth into their senior design projects. This year, one team got everybody else's teeth into it, too.

Five Rice seniors have created a portable dental suction device, an inexpensive, battery-powered version of the vacuum system commonly used in dentists' offices to remove blood and saliva from a patient's mouth.

Future antibiotics? Blasting silver nitrate solution with electron beam

Writing in the International Journal of Nanoparticles, Rani Pattabi and colleagues at Mangalore University, explain how blasting silver nitrate solution with an electron beam can generate nanoparticles that are more effective at killing all kinds of bacteria, including gram-negative species that are not harmed by conventional antibacterial agents.

Residential care home workers need more training to give older people a 'home for life'

Carers working in residential homes need funding and support to upskill to ensure more older people have a home for life instead of being transferred to hospitals and nursing homes, according to a new report.

Research from the University of Warwick and the University of West England is calling for social care home workers to be trained in basic clinical nursing skills to meet the changing needs of residents as they get older.

The report, funded by the Joseph Rowntree Foundation, also recommends a new registration system with formal qualifications for social care staff.

Temperature and salt levels of the Western Mediterranean are on the increase

Temperature and salt levels of the Western Mediterranean are on the increase

Spanish scientists have analysed the temperature and salt levels of the Western Mediterranean Sea between 1943 and 2000 to study the evolution of each variable. Their research shows that, since at least the 1940s, the deep water has become progressively hotter and saltier, and that, since the 1990s, this process has speeded up.

The benefits of energy crop cultivation outweigh the costs

Champaign, Il – May 3, 2010 - An article in the current issue of Global Change Biology Bioenergy reveals that Miscanthus x giganteus, a perennial grass, could effectively reduce our dependence on fossil fuels, while lowering atmospheric CO2.

Estrogen-lowering drugs minimize surgery in breast cancer patients

Estrogen-lowering drugs minimize surgery in breast cancer patients

A nationwide study has confirmed the benefit of giving estrogen-lowering drugs before surgery to breast cancer patients. The treatment increased the likelihood that women could undergo breast-conservation surgery, also called lumpectomy, instead of mastectomy.

'Scrubbing' chemical-contaminated buildings clean with lasers

Dhiren Barot was an al Qaeda operative involved in plots to blow up the London subway, among other targets. To maximize the damage and the terror, he planned to pack some of his bombs with toxic gas. Fortunately, in August 2004, British authorities nabbed Barot and his accomplices before they could carry out their attacks.
