Evacuating 70,000 sports fans in less than an hour?

What sports fan hasn't grumbled while waiting in a long, snaking lines to get into the stadium for the big game? It's enough to discourage even a diehard fan. But if you think it's a hassle getting into a sold-out game, imagine trying to get out after a bomb explodes—or even to get out under a bomb threat, for that matter.

Let's start with the emergency lights failing. If you're thinking of feeling your way out by the light of your cell phone, join the crowd—they're right beside you, pushing fifty-across and a thousand-deep in a stampede. It's everyone for himself.

Clovis, Mammoths and saber tooth cat extinction - not an asteroid, says new study

A team of researchers from the University of Arizona has revisited evidence pointing to a cataclysmic event thought by many scientists to have wiped out the North American megafauna – such as mammoths, saber tooth cats, giant ground sloths and Dire wolves – along with the Clovis hunter-gatherer culture some 13,000 years ago. The team obtained their findings and published them in the Proceedings of the National Academy of Sciences (PNAS).

Girls and young women who drink alcohol increase their risk of benign (noncancerous) breast disease, says a study by researchers at Washington University School of Medicine in St. Louis and Harvard University. Benign breast disease increases the risk for developing breast cancer.

Energy conservation in south could save billions, create jobs

DURHAM, N.C. – Energy-efficiency measures in the southern U.S. could save consumers $41 billion on their energy bills, open 380,000 new jobs, and save 8.6 billion gallons of water by 2020, according to a new study from the Nicholas Institute for Environmental Policy Solutions at Duke University and the Georgia Institute of Technology. The study concludes that investing $200 billion in energy efficiency programs by 2030 could return $448 billion in savings.

Natural gas potential assessed in Eastern Mediterranean

An estimated 122 trillion cubic feet (tcf) (mean estimate) of undiscovered, technically recoverable natural gas are in the Levant Basin Province, located in the Eastern Mediterranean region.

Technically recoverable resources are those producible using currently available technology and industry practices.

This is the first U.S. Geological Survey assessment of this basin to identify potentially extractable resources.

Annual chlamydia screening may not protect women from pelvic inflammatory disease

It is unlikely that single screening for chlamydia will prevent women developing pelvic inflammatory disease in the following year, according to research published on bmj.com today.

The study concludes that most cases of pelvic inflammatory disease occurred in women who did not have chlamydia infection when they were screened, suggesting they may have become infected later.

Family tree research can open a 'Pandora's Box' of secrets that may cause rifts, research says

People researching their ancestors can open a "Pandora's Box" of secrets that may cause conflict and widen rifts in the family, new research says.

While most people derive pleasure and satisfaction from researching their ancestry, for some it brings to light "secrets and skeletons", the study says.

Dr Anne-Marie Kramer, of the University of Warwick, told the British Sociological Association's annual conference in Glasgow today [9 April] that of 224 people who gave her details of family history research, around 30 mentioned conflict.

Researchers find compound effective in destroying antibiotic-resistant biofilms

Researchers at North Carolina State University have found a chemical compound that, when used in conjunction with conventional antibiotics, is effective in destroying biofilms produced by antibiotic-resistant strains of bacteria such as the Staphylococcus strain MRSA and Acinetobacter. The compound also re-sentsitizes those bacteria to antibiotics.

Different strokes for married folks?

Death, injury benefits a casualty of new war strategy, study says

CHAMPAIGN, Ill. — A hole in public policy is shortchanging U.S. soldiers and civilian workers who become casualties of a new-age war strategy that leans heavily on private contractors, a new University of Illinois study says.

Law and labor professor Michael LeRoy says contractors employ workers who now perform risky duties such as transportation and security that were once handled by the military, and also routinely supervise troops on non-combat projects such as building roads and schools.

How dangerous are air pollutants really?

Through this system, it will be possible for the first time ever to channel substances from the air, under precisely controlled conditions, through the lung cells or skin cells, and simultaneously observe the reactions of these cells under the microscope.
