High levels of prenatal smoking exposure affect sleep patterns in preterm neonates
A study in the Dec. 1 issue of the journal Sleep is the first to show that high levels of prenatal smoking exposure strongly modify sleep patterns in preterm neonates, which places infants at a higher risk for developmental difficulties that could persist throughout early and middle childhood.   view more (2008-12-01)

New method for tracing metal pollution back to its sources
A new way of pinpointing where zinc pollution in the atmosphere comes from could improve pollution monitoring and regulation, says research out this week in the journal Analytical Chemistry.   view more (2008-11-20)

Bottoms up: Individualists more likely to be problem drinkers
What makes residents of certain states or countries more likely to consume more alcohol? According to a new study in the Journal of Consumer Research, high levels of individualism lead to more problem drinking.   view more (2008-11-18)

Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days.   view more (2008-11-06)

Hydrogen tank lighter than battery
Dutch-sponsored researcher Robin Gremaud has shown that an alloy of the metals magnesium, titanium and nickel is excellent at absorbing hydrogen.   view more (2008-11-05)

Gaining too much weight during pregnancy nearly doubles risk of having a heavy baby
A study by the Kaiser Permanente Center for Health Research of more than 40,000 women and their babies found that women who gained more than 40 pounds during their pregnancies were nearly twice as likely to have a heavy baby.   view more (2008-10-31)

Metal hazard from table wines
Potentially hazardous levels of metal ions are present in many commercially available wines. An analysis of reported levels of metals in wines from sixteen different countries, published in the open access Chemistry Central Journal, found that only those from Argentina, Brazil and Italy did not... view more (2008-10-30)

Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the... view more (2008-10-28)

Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics.   view more (2008-10-23)

Secret Lives of Catalysts Revealed
The first-ever glimpse of nanoscale catalysts in action could lead to improved pollution control and fuel cell technologies. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed catalysts restructuring themselves in response to various gases swirling around... view more (2008-10-22)

Scientists propose the creation of a new type of seed bank
While an international seed bank in a Norwegian island has been gathering news about its agricultural collection, a group of U.S. scientists has just published an article outlining a different kind of seed bank, one that proposes the gathering of wild species -- at intervals in the future --... view more (2008-10-16)

Men who never smoke live longer, better lives than heavy smokers
Health-related quality of life appears to deteriorate as the number of cigarettes smoked per day increases, even in individuals who subsequently quit smoking, according to a report in the October 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.   view more (2008-10-14)

Opening a can of worms: Serendipitous discovery reveals earthworms more diverse than first thought
Scientists have found that the UK's common or garden earthworms are far more diverse than previously thought, a discovery with important consequences for agriculture.   view more (2008-10-10)

Promising new material that could improve gas mileage
With gasoline at high prices, it's disheartening to know that up to three-quarters of the potential energy you are paying for is wasted. A good deal of it goes right out the tailpipe instead of powering your car.   view more (2008-10-10)

Waterborne disease risk upped in Great Lakes
An anticipated increased incidence of climate-related extreme rainfall events in the Great Lakes region may raise the public health risk for the 40 million people who depend on the lakes for their drinking water, according to a new study.   view more (2008-10-09)

More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope.   view more (2008-10-02)

Drinking alcohol before 15 years of age is risky for later alcohol problems
It may seem like a minor point, but it matters when someone takes their first drink of alcohol relative to later development of alcohol problems. A new study of the relationship between age at first drink (AFD) and the risk of developing alcohol-use disorders (AUDs) during adulthood has found that... view more (2008-09-30)

New research shows why metal alloys degrade
Metal alloys can fail unexpectedly in a wide range of applications---from jet engines to satellites to cell phones---and new research from the University of Michigan helps to explain why.   view more (2008-09-25)

An analysis of the surgical and perioperative complications in right hepatectomies
Adult living related liver donors play an essential role in filling the gap of transplants needed due to a heavy shortage of cadaveric donations.   view more (2008-09-18)

Cutting calories could limit muscle wasting in later years
Chemical concoctions can smooth over wrinkles and hide those pesky grays, but what about the signs of aging that aren't so easy to fix, such as losing muscle mass? Cutting calories early could help, say University of Florida researchers who studied the phenomenon in rats.   view more (2008-09-17)

U-M physicists' analysis leads to discovery of new particle
University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton.   view more (2008-09-11)

Fuel-saving designs improve efficiency of hydraulic systems
Researchers at Purdue University have shown how to reduce fuel consumption and dramatically improve the efficiency of hydraulic pumps and motors in heavy construction equipment.   view more (2008-09-10)

Tracking Down the Menace in Mexico City Smog
A new report by scientists who are part of the international MILAGRO Campaign indicates that some of the most harmful air pollution in Mexico City may not come from motor vehicles but instead originates with industrial sources - and that the culprit may be garbage incineration.   view more (2008-09-08)

Study shows heavy snoring is an independent risk factor for carotid atherosclerosis
A study in the Sept. 1 issue of the journal Sleep shows that objectively measured heavy snoring is an independent risk factor for early carotid atherosclerosis, which may progress to be associated with stroke.   view more (2008-09-02)

Fingerprint analysis technique could be used to identify bombmakers
University of Leicester experts have held discussions with military personnel in Afghanistan following the discovery of new technology to identify fingerprints on metal.   view more (2008-08-27)
