Major flooding risk could span decades after Chinese earthquake

Up to 20 million people, thousands of whom are already displaced from their homes following the devastating Chinese earthquake, are at increased risk from flooding and major power shortages in the massive Sichuan Basin over the next few decades and possibly centuries.

Dr Alex Densmore, a geographer from Durham University, makes the observations on returning from carrying out investigative fieldwork in the China earthquake zone, where nearly 100,000 people were killed in May 2008. He has been studying the active faults in Sichuan for the past eight years.

Scientists uncover Ebola cell-invasion strategy

GALVESTON, Texas — University of Texas Medical Branch at Galveston researchers have discovered a key biochemical link in the process by which the Ebola Zaire virus infects cells — a critical step to finding a way to treat the deadly disease produced by the virus.

Probably wireless

Wireless Sensor Networks (WSNs) used to detect and report events including hurricanes, earthquakes, and forest fires and for military surveillance and antiterrorist activities are prone to subterfuge. In the International Journal of Security and Networks, computer scientists at Florida Atlantic University describe a new antihacking system to protect WSNs.

Fermilab physicists discover 'doubly strange' particle

Batavia, Ill. - Physicists of the DZero experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b (Ωb). The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass.

Participating in religion may make adolescents from certain races more depressed

COLUMBUS, Ohio -- One of the few studies to look at the effects of religious participation on the mental health of minorities suggests that for some of them, religion may actually be contributing to adolescent depression.

Previous research has shown that teens who are active in religious services are depressed less often because it provides these adolescents with social support and a sense of belonging.

1 in 2 adults at risk for painful knee arthritis

ATLANTA, September 3, 2008– A landmark government study suggests nearly one in two people (46%) will develop painful knee osteoarthritis over their lifetime, with the highest risk among those who are obese. According to the Arthritis Foundation, the study underscores the immediate need for the public to understand what they can do to reduce the tremendous pain, disability and cost associated with arthritis.

A virtuous cycle: Safety in numbers for riders

It seems paradoxical but the more people ride bicycles on our city streets, the less likely they are to be injured in traffic accidents.

International research reveals that as cycling participation increases, a cyclist is far less likely to collide with a motor vehicle or suffer injury and death - and what's true for cyclists is true for pedestrians. And it's not simply because there are fewer cars on the roads, but because motorists seem to change their behaviour and drive more safely when they see more cyclists and pedestrians around.

How Salmonella bacteria contaminate salad leaves -- it's not rocket science

How Salmonella bacteria can cause food poisoning by attaching to salad leaves is revealed in new research presented today (3 September) at the 21st International ICFMH Symposium 'Food Micro 2008' conference in Aberdeen.

The new study shows how some Salmonella bacteria use the long stringy appendages they normally use to help them 'swim' and move about to attach themselves to salad leaves and other vegetables, causing contamination and a health risk.

Researchers locate geographic origins from DNA

ITHACA, N.Y. - One day soon, you may be able to pinpoint the geographic origins of your ancestors based on analysis of your DNA.

A study published online this week in Nature by an international team that included Cornell University researchers describes the use of DNA to predict the geographic origins of individuals from a sample of Europeans, often within a few hundred kilometers of where they were born.

Biological invasions increasing due to freshwater impoundments, says CU-Boulder study

The growing number of dams and other impoundments is increasing the number of invasive species and the speed at which they spread, putting natural lakes at risk, says a study led by the University of Colorado at Boulder.

Prehistoric funerary precinct excavated in northern Israel

Hebrew University excavations in the north of Israel have revealed a prehistoric funerary precinct dating back to 6,750-8,500 BCE.

The precinct, a massive walled enclosure measuring 10 meters by at least 20 meters, was discovered at excavations being undertaken at Kfar HaHoresh. The Pre-Pottery Neolithic B site in the Nazareth hills of the lower Galilee is interpreted as having been a regional funerary and cult center for nearby lowland villages.

Fraunhofer in Korea -- trends for mega cities

This press release is also available in German.

Housing as far as the eye can see – Seoul is one of the world's mega cities. South Korea's capital city has undergone exponential growth over the past few decades: Its population has quadrupled in fifty years. Ten million people live within the city boundaries today. If the count is extended to cover the metropolitan region surrounding the city, it comes to over 20 million. The population growth has had a dramatic impact on the environment, bringing about a huge increase in traffic noise and air pollution.

Cosmic connections: Imperial scientist locates the origin of cosmic dust

The research, published in the journal Geology, shows that some of the cosmic dust falling to Earth comes from an ancient asteroid belt between Jupiter and Mars. This research improves our knowledge of the solar system, and could provide a new and inexpensive method for understanding space.

Children with TVs in their room sleep less

Middle school children who have a television or computer in their room sleep less during the school year, watch more TV, play more computer games and surf the net more than their peers who don't – reveals joint research conducted by the University of Haifa and Jezreel Valley College.

Legal to freeze assets of Somalis in Sweden

The freezing of assets of the three Somalis residing in Sweden was not an infringement of international law. Those who criticize the action are undermining the legitimacy of UN sanctions, according to Fredrik Stenhammar, a doctoral candidate at the Department of Law, Stockholm University, in Sweden.
