Science, not romance, controls mating at Smithsonian's National Zoo

This Valentine’s Day, Cupid won’t be making a stop at the Smithsonian’s National Zoo. Unlike the spontaneous attraction that most humans equate with love and romance, mating and dating at the National Zoo is planned, strategic and science-based—quite an unromantic encounter.

Moss protein plays role in Alzheimer's disease

Preventing Alzheimer’s from developing is a goal of Raphael Kopan, Ph.D., professor of molecular biology and pharmacology at the Washington University School of Medicine. The moss plant (Physcomitrella patens) studied in the laboratory of Ralph S. Quatrano, Ph.D., Spencer T. Olin Professor and chair of the WUSTL biology department on the Danforth Campus, might inch Kopan toward that goal. Here’s how.

Exploring homicide in an international context

From cross-national to country-specific empirical analyses and exploratory studies, the special issue, guest edited by Indiana University’s William Alex Pridemore, examines homicide from diverse global, gender, age, and cultural directions, looking at such wide-ranging concepts as:

  • The association between alcohol consumption and homicide rates in Europe

  • How economic inequality affects homicide rates in 14 developed democracies

Workplace autopilot threatens security risk perception

Safeguarding sensitive information - no matter how sophisticated the IT system - can never be foolproof, according to research published this week by Leeds University Business School.

Listening for the cosmic symphony: New SU supercomputer will help scientists listen for black holes

Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole. The supercomputer, dubbed SUGAR (SU Gravitational and Relativity Cluster), will soon receive massive amounts of data from the California Institute of Technology (Caltech) that was collected over a two-year period at the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO is funded by the National Science Foundation and operated by Caltech and the Massachusetts Institute of Technology.

Studying rivers for clues to global carbon cycle

EVANSTON, Ill. --- In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part by studying one important segment -- rivers.

Discovery of good -- and bad -- liver stem cells raises possibility of new treatment

Many scientists believe up to 40 percent of liver cancer is caused by stem cells gone wild – master cells in the organ that have lost all growth control. But, despite years spent looking, no one has ever found these liver “cancer stem cells” – or even normal stem cells in the organ. Until now.

Mock CPR 'codes' expose weaknesses in hospital emergency response for children

Staging mock cardiac and respiratory arrests - “code” situations in hospital parlance - easily expose common failures in rapid response with CPR and other life-saving care for children and also set up powerful incentives to sharpen emergency skills and move fast to use them, suggests a study from the Johns Hopkins Children’s Center.

Study confirms that low-calorie sweeteners are helpful in weight control

Unravelling the Northwest's Viking past

The blood of the Vikings is still coursing through the veins of men living in the North West of England — according to a new study which has been just published.

Focusing on the Wirral in Merseyside and West Lancashire the study of 100 men, whose surnames were in existence as far back as medieval times, has revealed that 50 per cent of their DNA is specifically linked to Scandinavian ancestry.
