Daylight Saving Time: More Trouble Than It's Worth?

If you’re feeling tired due to the daylight savings shift, you’re not alone. One researcher at Washington University says the time change may cause more problems than it solves.

Erik Herzog studies the biological clocks of mammals. He says several studies have shown that daylight saving is hard on us humans, especially the “spring ahead.” Effects like sleep deprivation result in increased traffic accidents for three days after the time change.

Herzog says the effect in the fall is the opposite – there are fewer traffic accidents – but that effect lasts only one day.

Seated in his office on the second floor of Brookings Hall on the eastern edge of the Washington University campus, Provost Holden Thorp has a pretty good metaphor for what his job entails compared with that of university Chancellor Mark Wrighton.

“You can see the chancellor’s office is across the hall,” Thorp said in a recent interview. “His office faces the park and the Arch and downtown. My office is on this side and faces out to the old quad.

Obesity has increased dramatically in the United States over the past several decades.

In Missouri, almost two-thirds of adults ― and more than a quarter of children and teens ― are either overweight or obese.

Research led by Washington University confirms that medication and lifestyle changes are safer and more effective at preventing certain strokes than surgery.

Most strokes are caused by a reduction in blood flow to the brain ― usually from a blocked artery in the heart or neck. In about a tenth of cases, a narrowed brain artery is to blame.

A multi-disciplinary study released today finds that in relation to school dropout rates, health plays a bigger role than one might think.

The study is part of ‘For The Sake of All,’ a five part series from Washington University and Saint Louis University that focuses on the health of African Americans in the St. Louis region.

Employment in the field of information security, web development and computer networks—cybersecurity—is expected to increase 22 percent by 2020, according to the Bureau of Labor and Statistics. Washington University and Fontbonne University are offering new cybersecurity programs this Fall in response to the growing demand in the workforce for people in this field.

This summer, the Washington University School of Medicine intends to break ground on a new research facility.

The six-story, 138,000 square-foot facility is part of an ongoing effort by the university to encourage interdisciplinary research in biology and medicine.

The $75 million project is slated to house researchers involved in genetics, genomics and biological regeneration.

Washington University says the new facility will help replace aging laboratories with energy-efficient, flexible and open research space.

It has been just over three months since the federal spending cuts known as sequestration first took effect.

A handful of programs were spared — but not scientific research, which amounts to about $140 billion in annual government spending.

As St. Louis Public Radio’s Véronique LaCapra found out, at universities here in St. Louis, some scientists are worried about what the budget cuts will mean for their research — and for their students.

Four of the top twenty-one influential researchers in the world live in the St. Louis area.

The researchers are from Washington University in St. Louis and all are in the field of genomics.  The findings come from Thomson Reuters ScienceWatch, an open web resource for science metrics and analysis.

A Washington University researcher has received a $100,000 global health grant from the Bill & Melinda Gates Foundation to support research focused on preventing the transmission of parasitic diseases in developing countries.

Although there are drugs to help kill parasitic worms and their eggs in the human body, stopping their transmission in the environment is challenging.


One of the country’s largest startup incubators will soon be moving into the Cortex bioscience district in St. Louis.

The move marks Cambridge Innovation Center’s first expansion out of the Boston area, where it houses more than 500 small to mid-sized companies.

CIC’s president and CEO, Ranch Kimball, says he expects the new St. Louis facility to attract mostly technology startups, but says CIC will be open to a variety of businesses.

If you live in any big city in the Midwest, and St. Louis in particular, you’re probably all too familiar with the site of vacant, empty land where homes and businesses used to be. 

This issue of vacant land in an otherwise urban environment presents tough challenges for cities.  This weekend ground will be broken on several projects which aim to change the way neighborhoods and cities deal with vacant property.

Researchers from all over the world are gathering today at Washington University for a conference on global health.

The event is the first to be organized by the university’s recently-created Center for Global Health and Infectious Disease. St. Louis Public Radio’s Véronique LaCapra spoke with the Center’s director Bill Powderly about its mission.

Researchers at Washington University and the University of Illinois at Urbana-Champaign have developed miniaturized electronic devices small enough to safely insert into the brains of live mice. The tiny wireless devices can target specific brain cells and influence behavior.

University of Illinois materials scientist John Rogers co-led the study and helped design the devices. He says they’re on the same size-scale as cells, so they can penetrate far down into the brain.

Researchers at Washington University have genetically-engineered cells to react to light.

By taking light-sensing receptors from the eye — called opsins — and inserting them into immune cells, the researchers were able to trick the cells into moving toward a laser beam, in the same way they would move toward a bacterial infection.

Washington University molecular biologist N. Gautam led the research.


In 2005, President Bill Clinton established the Clinton Global Initiative (CGI).  The goal of the ongoing project is to “create and implement innovative solutions to the world's most pressing challenges.”

For many years, it’s been thought that Stonehenge, the ancient monolith in southwestern England, was created by Druids around 460 B.C.  

New research shows that is incorrect.  “Even today, a lot of people think Stonehenge is connected to Druids.  We are very certain from radon carbon dating that it happened before,” said British archaeologist Mike Parker Pearson, Professor at the Institute of Archaeology, University College London and leader of the Stonehenge Riverside Project.
