UW study links poor sleep to potential for Alzheimer’s

Channel3000.com

A study by University of Wisconsin researchers suggests that poor sleep in middle age could be one of the first symptoms of Alzheimer’s disease. Senior author Dr. Ruth Benca said in a release that despite correlation, the study doesn’t show whether poor sleep causes amyloid plaques to develop in the brain or whether amyloid plagues prevent quality sleep.

Inside America’s secretive biolabs

USA Today

Vials of bioterror bacteria have gone missing. Lab mice infected with deadly viruses have escaped, and wild rodents have been found making nests with research waste. Cattle infected in a university’s vaccine experiments were repeatedly sent to slaughter and their meat sold for human consumption. Gear meant to protect lab workers from lethal viruses such as Ebola and bird flu has failed, repeatedly.

State incidents highlight bioterror lab concerns

USA Today

High-profile biological lab accidents last year and this week with deadly pathogens like anthrax and Ebola put secretive bioterror labs under the microscope nationwide. The “high-containment” labs operate largely out of the public view in Wisconsin, even as mistakes happen.

‘Nano-paper’ chips end up in compost heaps, not landfills

Engadget

Today’s cast-off gadgets are far more likely to end up in a landfill than they are being responsibly disposed of. In fact, 41.8 million tons of e-waste were scrapped last year alone. To combat this, a team from the University of Wisconsin-Madison has invented a radically new kind of ecologically-friendly semiconductor chip made from wood. No, seriously.

The Open Source Seed Initiative wants to make carrot seeds more like software. That may seem like an odd project, but consider this: It’s currently possible to patent plants with certain traits, whether they are created through traditional breeding or biotech modification.

Madison-based scientists aim to bring home MIAs the military missed

Wisconsin State Journal

A group of Madison-based scientists is forming a team to find the remains of long-lost World War II veterans and bring them home for proper burial. If private fundraising goals are met, the Missing In Action Recovery and Identification Project would meld the skills of UW-Madison scholars of history, genetic analysis and archeology.

The dynamics of disaster

In August 2003, hundreds of Parisians returned from their summer holidays to an unholy smell. Ascending the stairs in their apartment buildings, they found the source: dead bodies. Between August 1st and 20th, a heat wave baked Europe, and nearly 15,000 people died in France alone. Richard Keller’s intrepid new book, Fatal Isolation, is a social autopsy of those deaths.

New UW program could help reunite families with remains of MIA military members

WKOW TV

Bill Eisch has spent the past two decades scouring Department of Defense reports and other historical documents trying to find answers. A new project at UW-Madison aims to help reunite people like Eisch with the remains of those declared missing in action. The effort is inspired by the case of PFC Lawrence Gordon, a man who fought for the United States, died in France, and never made it back home.

UW launches initiative to identify and recover missing soldiers

Milwaukee Journal Sentinel

A year after using cutting-edge DNA analysis to identify the remains of an American soldier mistakenly buried with the enemy after World War II, the University of Wisconsin-Madison announced Wednesday it will put its expertise in history, archaeology and forensic and genetic analysis behind the U.S. government’s tedious efforts to identify and recover other missing service members.

Did a megaflood kill off America’s first metropolis?

Daily Mail (UK)

It was America’s first metropolis.Cahokia, the largest prehistoric settlement in the Americas north of Mexico, flourished in the 1200s, with a population of 20,000 people at its peak – but was mysterious abandoned by 1400. Now researchers think they know why – a megaflood that raised the Mississippi River by 10m.

Study: Drinking questions from doctor don’t help those most in need of help

Alcohol consumption questions have become commonplace in the repertoire of a doctor’s assessment of a patient in Wisconsin, but the brief dialog isn’t prompting those most in need to seek treatment, a study shows. The study, performed by UW-Madison assistant professor of social work Joseph Glass, said the process known as screening and brief intervention helps people with milder drinking problems but not those who need counseling or treatment.

Mississippi floods shaped rise, collapse of prehistoric city

National Geographic

Researchers have long debated the reasons behind the rapid rise and swift disappearance of Cahokia, a sprawling, ancient city-state near the modern city of St. Louis. Now an analysis of sediment cores reveals that the city’s ups and downs correspond to the timing of Mississippi River megafloods, according to a recent study from University of Wisconsin geographers Sam Munoz and Jack Williams.

Short-term debt can depress more than your finances

HealthDay News

People with short-term debt, such as overdue bills or credit card debt, are more likely to be depressed than those who carry long-term debt through mortgages and other big loans, a new study suggests. “A 10 percent increase in short-term debt was associated with a 24 percent increase in depression symptoms,” said the study’s lead author, J. Michael Collins, faculty director of the Center for Financial Security at the University of Wisconsin-Madison.

Research by University of Wisconsin professor Holly Gibbs found that the Brazilian soy industry’s moratorium significantly decreased deforestation in the Brazilian Amazon, but that rates of deforestation in the Cerrado and other eco regions not covered by the moratorium, as well as in the Amazon biome outside of Brazil, increased.

Flooding May Have Contributed to Cahokia’s Decline

Archaeology Magazine

MADISON, WISCONSIN—Sediment cores from Horseshoe Lake, located in the Mississippi floodplain near the center of Cahokia, and Grassy Lake, roughly 120 miles downstream, provide clues to the rise and fall of the ancient city, according to geographers Samuel Munoz and Jack Williams of the University of Wisconsin, Madison.

Researchers: Major floods coincided with desertion of Cahokia Mounds

St. Louis Public Radio

The people who built and lived among the tall, sculpted mounds now preserved at Cahokia Mounds Historic Site have long presented a mystery to archeologists.One of the biggest mysteries: Why did they leave? A team of UW-Madison geographers studying pollen deposits buried in the sediment under Horseshoe Lake may have stumbled upon new evidence that helps explain Cahokia’s decline.

Floods might have doomed prehistoric American city

Nature

Cahokia was a pretty big deal in the 1100s. Founded by a complex cultural group that built tall mounds and sweeping plazas, the city near present-day St Louis, Missouri, was home to tens of thousands of people. But its population began declining around 1200, and by 1350, Cahokia was a ghost town.

What your smile says about where you’re from

If you come from a country of immigrants, you’re more likely to crack a friendly smile on the street. That’s the conclusion of a new study, which may explain why Americans beam more than their Chinese and Russian counterparts. Scientists have known for decades that societies have their own unwritten rules about when it’s appropriate to smile, frown, or get angry. These rules are part of a country’s “emotion culture,” the norms that influence how and when people express whether they’re pleased or upset. Researchers often study these differences geographically, finding that the United States and the West tend to be more expressive than China and the East. But those geographical studies overlook the important role migration played in shaping emotion culture, says Paula Niedenthal, a psychologist at the University of Wisconsin, Madison.

Ancient Native American city may have been done in by Mississippi floods

Ars Technica

Long before Europeans arrived to settle St. Louis, an impressive human construction stood on the eastern side of the Mississippi River. It was the Native American city of Cahokia. At its height, tens of thousands lived in and around Cahokia, leaving behind great earthen mounds as testament. The largest still stands about a hundred feet tall today, minus what was likely a temple that once adorned its crest.
