Water hits and sticks: Findings challenge a century of assumptions about soil hydrology

CORVALLIS, Ore. – Researchers have discovered that some of the most fundamental assumptions about how water moves through soil in a seasonally dry climate such as the Pacific Northwest are incorrect – and that a century of research based on those assumptions will have to be reconsidered.

A new study by scientists from Oregon State University and the Environmental Protection Agency showed – much to the surprise of the researchers – that soil clings tenaciously to the first precipitation after a dry summer, and holds it so tightly that it almost never mixes with other water.

Go easy on the environment -- and our wallets, says Generation Y

EAST LANSING, Mich. — When it comes to saving the environment, Generation Y is all for it – as long as it comes with an economic benefit, according to new research by Michigan State University in collaboration with Deloitte LLP.

Based on a scientific survey of 18- to 30-year-olds, researchers from MSU's Eli Broad Graduate School of Management found that young consumers will not pay a premium price for an automobile simply because it is environmentally friendly. Instead, the determining factor – by far – is fuel efficiency.

Obesity ups cancer risk, and here's how

Obesity comes with plenty of health risks, but there's one that's perhaps not so well known: an increased risk of developing cancer, and especially certain types of cancer like liver cancer. Now, a group of researchers reporting in the January 22nd issue of the journal Cell, a Cell Press publication, have confirmed in mice that obesity does indeed act as a "bona fide tumor promoter." They also have good evidence to explain how that happens.

Adverse reactions from gadolinium-based contrast agents used during MRI rarely occur, study suggests

Acute adverse reactions from gadolinium-based contrast agents used during magnetic resonance imaging (MRI) to help improve the information seen on the images rarely occur, according to a study published in the February issue of the American Journal of Roentgenology.

Engineers: New sensor could help treat, combat diabetes, other diseases

GAINESVILLE, Fla. — A tiny new sensor could provide fresh, inexpensive diagnosis and treatment methods for people suffering from a variety of diseases.

University of Florida engineers have designed and tested versions of the sensor for applications ranging from monitoring diabetics' glucose levels via their breath to detecting possible indicators of breast cancer in saliva. They say early results are promising — particularly considering that the sensor can be mass produced inexpensively with technology already widely used for making chips in cell phones and other devices.

UVa engineers find significant environmental impacts with algae-based biofuel

With many companies investing heavily in algae-based biofuels, researchers from the University of Virginia's Department of Civil and Environmental Engineering have found there are significant environmental hurdles to overcome before fuel production ramps up. They propose using wastewater as a solution to some of these challenges.

These findings come after ExxonMobil invested $600 million last summer and the U.S. Department of Energy announced last week that it is awarding $78 million in stimulus money for research and development of the biofuel.

Scientists using X-ray vision to produce more nutritious flour

Pioneering research combining plant breeding and high-intensity x-rays is being used by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) to explore the possibility of developing wheat which could be used to make potentially life-saving mineral enriched flour. The research is highlighted in the latest issue of Business, the quarterly highlights magazine of BBSRC.

Researchers develop new bushfire warning device

A new, low-cost bushfire detection and monitoring system is being developed by University of Adelaide researchers using mobile communications technology.

The same technology used to send SMS messages on mobile phones could be used to develop an efficient and cost-effective early warning message to authorities and people living in fire-risk areas, according to researchers from the School of Electrical and Electronic Engineering.

Heart attack victims who have ECGs in the field experience shorter time-to-treatment

A recent study found that individuals experiencing chest pain who had electrocardiogram (ECG or EKG) assessments prior to arriving at the hospital experienced a significantly reduced time-to-treatment or door-to-balloon (D2B) time. When EMS personnel responding to cardiac emergencies obtained ECGs of the subjects in the field, the mean D2B time was 60.2 minutes compared with 90.5 minutes for in-hospital ECGs.

Cave reveals Southwest's abrupt climate swings during Ice Age

Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic, according to new research.

The finding is the first to document that the abrupt changes in Ice Age climate known from Greenland also occurred in the southwestern U.S., said co-author Julia E. Cole of the University of Arizona in Tucson.

Springtime ozone increases over western North America linked to emissions abroad

Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. These increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study. Published online Wednesday, Jan. 20, in the journal Nature, the study analyzed large sets of ozone data captured since 1984.

Oral COTI-2 is effective in a second animal model of human pancreatic cancer

London, Ontario (January 20, 2010): Critical Outcome Technologies Inc. (COTI) (TSX Venture: COT)announced more positive results today from animal experiments carried out at a prominent Canadian cancer research facility. This new series of experiments adds to the impressive data package for COTI-2, demonstrating efficacy both as a single agent and in combination with current first line therapies, as well as low toxicity in several different animal models of human cancers.

An electrifying advance toward tomorrow's power suits

Could powering an iPod or cell phone become as easy as plugging it into your tee shirt or jeans, and then recharging the clothing overnight? Scientists in California are reporting an advance in that direction with an easier way of changing ordinary cotton and polyester into "conductive energy textiles" — e-Textiles that double as a rechargeable battery. Their report on the research appears in ACS' Nano Letters, a monthly journal.
