Broken glass yields clues to climate change

Broken glass yields clues to climate change

Clues to future climate may be found in the way an ordinary drinking glass shatters.

Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart in patterns that are similar to the fragment patterns of broken glass and other brittle objects.

Enzyme cocktail could eliminate a step in biofuel process

Conversion of biomass to fuel requires several steps: chemical pretreatment to break up the biomass – often dilute (sulfuric) acid, detoxification to remove the toxic chemicals required in pretreatment, and microbial fermentation to convert the soluble sugars to fuels.

Newborns with low vitamin D levels at increased risk for respiratory infections

The vitamin D levels of newborn babies appear to predict their risk of respiratory infections during infancy and the occurrence of wheezing during early childhood, but not the risk of developing asthma. Results of a study in the January 2011 issue of Pediatrics support the theory that widespread vitamin D deficiency contributes to risk of infections.

How cells running on empty trigger fuel recycling

LA JOLLA, CA—Researchers at the Salk Institute for Biological Studies have discovered how AMPK, a metabolic master switch that springs into gear when cells run low on energy, revs up a cellular recycling program to free up essential molecular building blocks in times of need.

Texas AM professor helps develop first high-temp spin-field-effect transistor

COLLEGE STATION, Dec. 23, 2010 — An international team of researchers featuring Texas A&M University physicist Jairo Sinova has announced a breakthrough that gives a new spin to semiconductor nanoelectronics and the world of information technology.

The team has developed an electrically controllable device whose functionality is based on an electron's spin. Their results, the culmination of a 20-year scientific quest involving many international researchers and groups, are published in the current issue of Science.

Mortality rates are an unreliable metric for assessing hospital quality, study finds

BOSTON (December 22, 2010) -- Is quality in the eye of the beholder?

Researchers at Harvard Medical School and Massachusetts General Hospital have found wide disparities among four common measures of hospital-wide mortality rates, with competing methods yielding both higher- and lower-than-expected rates for the same Massachusetts hospitals during the same year.

Love-smitten consumers will do anything for their cars and guns

The way people treat their possessions looks like love, according to a new study in the Journal of Consumer Research.

"Is it possible for consumers to be in love with their possessions?" ask authors John L. Lastovicka (Arizona State University) and Nancy J. Sirianni (Texas Christian University). When it comes to cars, computers, bicycles, and firearms, the answer seems to be a resounding yes.
