Researchers analyze probability of hurricane-force winds in 35 East Coast, Gulf of Mexico cities
Hurricane-force winds are most likely to strike this year in Cape Hatteras, N.C., and Miami Beach and Naples, Fla., according to an analysis of coastal cities by a University of Central Florida professor and a Georgia researcher released today. Cape Hatteras has a 10.31 percent chance of experiencing hurricane-force winds this year, followed by Miami Beach at 10.16 percent and Naple
In a presentation today at the Conference on Lasers and Electro-Optics (CLEO), researchers from Cedars-Sinai Medical Center’s Biophotonics Research and Technology Development Laboratory described recent progress on a device that stimulates, collects and measures light emissions from body tissues to diagnose critical atherosclerotic plaques (vulnerable plaques) and aggressive brain tumors.
In both disease processes, early detection and precision can impact patient outcomes. Ath
Mix-and-shake procedure leads to instant glass microbubbles
Chemical engineers from Rice University have developed a fundamentally new approach – the most environmentally sensitive yet devised – for making tiny hollow spheres called microcapsules. Microcapsule research is one of the most active fields in applied nanotechnology, with dozens of companies either developing or using the tiny containers – usually smaller than living cells – to deliver everything from drugs and imaging ag
Woods Hole Center for Oceans and Human Health cruise provided timely data for shellfish managers
With shellfish beds from Maine to the Cape Cod coast closed from the largest outbreak of red tide in 12 years in Massachusetts Bay, scientists from the Woods Hole Oceanographic Institution (WHOI) are studying the algae that causes these “red tides” and providing information to coastal managers using new molecular techniques and oceanographic models.
After a recent research cr
Rensselaer Researchers Detail Potential for Smart Lighting in Science
“Smart” solid-state light sources now being developed not only have the potential to provide significant energy savings, but also offer new opportunities for applications that go well beyond the lighting provided by conventional incandescent and fluorescent sources, according to E. Fred Schubert and Jong Kyu Kim of Rensselaer Polytechnic Institute.

The same kind of chemical coating used to shed rainwater from aircraft and automobile windows also dramatically enhances the sensitivity and reaction time of hydrogen sensors. Hydrogen sensor technology is a critical component for safety and other practical concerns in the proposed hydrogen economy. For example, hydrogen sensors will detect leaks from hydrogen powered cars and fueling stations long before the gas becomes an explosive hazard.
The discovery was made by a team led by
OHSU scientist participates in study supporting wider use of commercial microarrays
Technology for analyzing gene expression must be standardized among laboratories and across platforms around the world to support this age of human genome exploration, an Oregon Health & Science University researcher says.
Otherwise, scientists using DNA microarrays, also known as gene chips, risk having their research results called into question, said Peter Spencer, Ph.D., professor of ne
Tufts researchers recently reported that while the leading source of calories in the average American diet used to be from white bread, that may have changed. Now, according to preliminary research conducted by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, Americans are drinking these calories instead. The research was presented in abstract form at the Experimental Biology Conference in April of this year and a more comprehensive paper is being de
Some century-old chemistry could have a strong impact on important issues in biosensors and other nanotech devices, according to a Purdue University research group.
A team led by Alexander Wei has shown that amines, a large and important class of organic molecules, when mixed with carbon disulfide, can bond to gold more robustly than thiols, which are commonly used materials for giving new functions to metal surfaces. Gold surfaces are often used as baseplates of sensors and in nanom
Biomedical engineers at Duke University’s Pratt School of Engineering have created a new three-dimensional ultrasound cardiac imaging probe. Inserted inside the esophagus, the probe creates a picture of the whole heart in the time it takes for current ultrasound technology to image a single heart cross section.
The new probe has considerable potential not only for evaluating the condition of the heart, but also for use in guiding therapeutic treatment devices, the researcher
An international team of scientists, led by researchers at the Woods Hole Oceanographic Institution, Scripps Institution of Oceanography, University of Oregon and University of Sydney, has discovered an active underwater volcano near the Samoan Island chain about 2,400 miles southwest of Hawaii.
During a research cruise to study the Samoan hot spot, scientists uncovered a submarine volcano growing in the summit crater of another larger underwater volcano, Vailulu’u. Research
Quick subconscious thinking decides ‘how much louder?’ and which muscles to use
How someone tells you to “keep quiet” affects whether or how you might comply. But what happens when you’re asked to “talk louder,” or you’re talking and the background noise level suddenly goes up?
Purdue University researchers found that how you get louder is a function of how you’re told to speak louder and environmental cues. Far more surprising, they discovered that tryin
Violence may be viewed as infectious disease
In a study designed to isolate the root causes of violent behavior, Harvard Medical School researchers found that young teens who witnessed gun violence were more than twice as likely as non-witnesses to commit violent crime themselves in the following years. The study will appear in the May 27 issue of Science.
“Based on this study’s results, showing the importance of personal contact with violence, the best model for violence
Consumers of organic food should be more inquisitive about its quality, if they want to make sure they get the ‘real thing’, say European experts.
A team of researchers leading a pan-European organic food project also recommends that shoppers tell retailers if they are satisfied or not with the products and the information provided on their labels.
The advice is among a series of recommendations given in three new booklets aimed at informing consumers about organic food
Type Ic supernovae, or hypernovae, may be source of powerful bursts
Observations by two of the world’s largest telescopes provide strong evidence that a peculiar type of exploding star may be the origin of elusive gamma-ray bursts that have puzzled scientists for more than 30 years.
A team of astronomers from Italy, Japan, Germany and the United States, including the University of California, Berkeley, conclude from observations with the Keck and Subaru telescopes in H
New research from the National Center for Atmospheric Research (NCAR) links a particular magnetic structure on the Sun with the genesis of powerful solar storms that can buffet Earth’s atmosphere. The research may enable scientists to create more accurate computer models of the solar storms, known as coronal mass ejections (CMEs), and could eventually point the way to forecasting the storms days before they occur. Sarah Gibson, a scientist at NCAR’s High Altitude Observatory (HAO), wil
