Data on today’s youth reveal childhood clues for later risk of STDs

Here’s yet another reason to focus on kids’ early years. Children who grow up in well-managed households, enjoy school, and have friends who stay out of trouble report fewer sexually transmitted diseases in young adulthood, according to a new analysis.

The findings, from University of Washington longitudinal surveys of nearly 2,000 participants, suggest that efforts to curb the spread of sexually transmitted diseases should begin years before most people start having sex. (more…)

Newly found tactics in offense-defense struggle with hepatitis C virus

The hepatitis C virus has a previously unrecognized tactic to outwit antiviral responses and sustain a long-term infection. It also turns out that some people are genetically equipped with a strong countermeasure to the virus’ attempt to weaken the attack on it.

The details of these findings suggest potential targets for treating HCV, according to a research team led by Dr. Ram Savan, assistant professor of immunology at the University of Washington. The study was published in Nature Immunology. (more…)

Fruit flies – fermented-fruit connoisseurs – are relentless party crashers

That fruit fly joining you just moments after you poured that first glass of cabernet, has just used its poppy-seed-sized brain to conduct a finely-choreographed search, one that’s been described for the first time by researchers at the University of Washington.

The search mission is another example of fruit flies executing complex behaviors with very little “computational” power, their brains having 100,000 neurons compared to house flies with 300,000 neurons and humans with 100 billion. (more…)

Schnellster Gletscher Grönlands: DLR-Satelliten TerraSAR-X und TanDEM-X ermitteln Rekordgeschwindigkeit

Seit den 1990er Jahren gilt der Jakobshavn Isbrae als der sich am schnellsten bewegende Gletscher Grönlands. Seine Geschwindigkeit ist nun drastisch gestiegen, mit Rekordwerten für 2012 und 2013 – so das Ergebnis von Wissenschaftlern der University of Washington und des Deutschen Zentrums für Luft- und Raumfahrt (DLR). Räumlich und zeitlich hochaufgelöste Daten der deutschen Radarsatelliten TerraSAR-X und TanDEM-X ermöglichten besonders präzise Berechnungen. Die neue Studie wurde am 3. Februar 2014 in “The Cryosphere” veröffentlicht, einer Fachzeitschrift der European Geosciences Union (EGU).

“Wir beobachten Jakobshavn Isbrae bereits seit Mitte 2008 regelmäßig mit dem TerraSAR-X-Satellit. Es ist wirklich beeindruckend zu sehen, wie stark dieser Gletscher sich innerhalb kürzester Zeit verändert”, so Mitautorin Dr. Dana Floricioiu vom Institut für Methodik der Fernerkundung des DLR-Earth Observation Center in Oberpfaffenhofen.

Deaths attributed directly to climate change cast pall over penguins

Climate change is killing penguin chicks from the world’s largest colony of Magellanic penguins, not just indirectly – by depriving them of food, as has been repeatedly documented for these and other seabirds – but directly as a result of drenching rainstorms and, at other times, heat, according to new findings from the University of Washington.

Too big for parents to sit over protectively, but still too young to have grown waterproof feathers, downy penguin chicks exposed to drenching rain can struggle and die of hypothermia in spite of the best efforts of their concerned parents. And during extreme heat, chicks without waterproofing can’t take a dip in cooling waters as adults can. (more…)

Weapons tied to repeat domestic abuse

Women are up to 83 percent more likely to experience repeat abuse by their male partners if a weapon is used in the initial abuse incident, according to a new study that has implications for victims, counselors and police.

Michigan State University researcher Amy Bonomi and colleagues studied the domestic abuse police reports of nearly 6,000 couples in Seattle during a two-year period. An estimated one in four women in the United States experience domestic violence at least once in their lifetime. (more…)

Nighttime smartphone use zaps workers’ energy

Using a smartphone to cram in more work at night results in less work the next day, indicates new research co-authored by a Michigan State University business scholar.

In a pair of studies surveying a broad spectrum of U.S. workers, Russell Johnson and colleagues found that people who monitored their smart phones for business purposes after 9 p.m. were more tired and were less engaged the following day on the job. (more…)

Facelift complications eased with help of new 3-D imaging technique

Millions of people each year remove wrinkles, soften creases and plump up their lips by injecting a gel-like material into their facial tissue. These cosmetic procedures are sometimes called “liquid facelifts” and are said to be minimally invasive.

It’s rare, but sometimes things go wrong. In a matter of minutes, patients’ skin can turn red or blotchy white and the injected area becomes painful. Vital blood supply to the face is restricted and if untreated, parts of the tissue will die. That scenario is irreversible and can leave deep scars. (more…)
