WEST LAFAYETTE, Ind. - Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures.
"Imagine you're a water molecule in a glass of ice water, and you're floating right on the boundary of the ice and the water," proposes Emory University physicist Eric Weeks. "So how do you know if you're a solid or a liquid?"
WEST LAFAYETTE, Ind. - Researchers are developing a new class of tiny mechanical devices containing vibrating, hair-thin structures that could be used to filter electronic signals in cell phones and for other more exotic applications.
Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, "supernovae" for short, certainly works: it's how dark energy was discovered in the first place. Other independent techniques, such as weak gravitational lensing and baryon acoustic oscillation, also promise great power but are as yet unproven.
There's no "silver bullet" gene or gene region that controls so-called complex traits in maize, commonly known as corn.
ANN ARBOR, Mich.---With school days just around the corner, a University of Michigan researcher has some advice for parents who want to increase their children's academic success.
What do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common?
Here's a question. How many gumballs of different sizes can fit in one of those containers at the mall so as to reward a well-spent quarter? It's hard to believe that most people never consider it even when guessing the number of candies in a bowl at Halloween.
A team of researchers, led by chemical engineering and materials science professor Michael Tsapatsis in the University of Minnesota's Institute of Technology, have developed a more energy-efficient method of chemical separations that could revolutionize processes in the petrochemical and biofuels industries.
Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.
The ability to separate and purify specific molecules in a chemical mixture is essential to chemical manufacturing.
Scientists have joined forces in a groundbreaking assessment on the status of marine fisheries and ecosystems.
The two-year study, led by Boris Worm of Dalhousie University and Ray Hilborn of the University of Washington and including an international team of 19 co-authors, shows that steps taken to curb overfishing are beginning to succeed in five of the 10 large marine ecosystems that the
The ocean's smallest swimming animals, such as jellyfish, can have a huge impact on large-scale ocean mixing, researchers have discovered.
Athens, Ga. -- Most parts of living organisms come packaged with ribbons. The ribbons are proteins -- chains of amino acids that must fold into three-dimensional structures to work properly. But when for any reason the ribbons fold incorrectly, bad things can happen, and in humans misfolded-protein disorders include Alzheimer's and Parkinson's diseases.
Mammals and many species of birds and fish are among evolution's "winners," while crocodiles, alligators and a reptile cousin of snakes known as the tuatara are among the losers, according to new research by UCLA scientists and colleagues.
RIVERSIDE, Calif. -- Evidence for life on Earth stretches back billions of years, with simple single-celled organisms like bacteria dominating the record. When multi-celled animal life appeared on the planet after 3 billion years of single cell organisms, animals diversified rapidly.
