Collaborative research reveals a new view of cell division
Basic research into the mechanisms of cell division, using eggs and embryos from frogs and starfish, has led researchers to an unexpected discovery about how animal cells control the forces that shape themselves. During a key point in cytokinesis a cell's cortex becomes an excitable medium resulting in waves that serve to regulate enzyme activities.

OU research team selected to develop aeroecology national research training program
A research team from the University of Oklahoma has been awarded a $2.9 million National Science Foundation grant to develop an aeroecology training program that will be used as a model at OU and other universities to train graduate students from science, technology, engineering and mathematics, and other disciplines. The program will fulfill a national need to train data scientists in the field of aeroecology and its rapidly growing use of Earth-observation data for societal benefits.

Researchers transform slow emitters into fast light sources
Phosphors are efficient light emitters but they're not optimal for high-speed communications because they turn on and off slowly. Researchers from Brown and Harvard have now found a way to modulate light from phosphor emitters three orders of magnitude faster using phase-change materials, which could make phosphors useful in a range of new optoelectronic applications.

Creating a new market for Northeast forest products
A new three-year study funded by a $390,000 National Science Foundation grant to researchers at the University of Massachusetts Amherst is expected to show that a strong new building material known as cross laminated timber (CLT) can incorporate currently underused wood species grown in the northeast United States, creating a market for local trees and opening jobs in rural communities.

CWRU biologists find keys to driving a cockroach
Researchers at Case Western Reserve University have identified neurons in a cockroach's brain that control whether the insect walks slow or fast, turns right or left or downshifts to climb. Electrical stimulation selectively applied to these central-complex cells alters reflexes and consistently causes the insects to replicate movements.

The ties that bind: WPI researchers search for the hidden genetic code across species
When species as different as humans and yeast share common genetic elements, those snippets of DNA are likely to perform fundamental biological functions. The National Science Foundation has awarded Worcester Polytechnic Institute $768,000 to identify such elements across all known genomes of plants, animals, fungi, and other complex organisms to gain insight into the roles they play. A team led by Dmitry Korkin will conduct the search using mathematical algorithms and advanced computing technology.

3-D map of the brain
The animal brain is so complex, it would take a supercomputer and vast amounts of data to create a detailed 3-D model of the billions of neurons that power it. But computer scientists and a professor of ophthalmology at the University of Utah have developed software that maps out a monkey's brain and more easily creates a 3-D model, providing a more complete picture of how the brain is wired.

Technology companies alone will need to fill more than 650,000 new jobs by 2018.

Study finds key molecular mechanism regulating plant translational activity
Plants can't get up and run away when they're being attacked, so they need mechanisms to rapidly respond to a stressful event and then quickly transition back to normal conditions when the stress level subsides. In a paper published in the journal Cell, North Carolina State University researchers show how plants handle -- at the molecular level -- the release of ethylene, an important gaseous stress hormone that, among other functions, regulates plant growth and stimulates the fruit ripening process.

Astronomers peer inside stars, finding giant magnets
Caltech astronomers have for the first time probed the magnetic fields in the mysterious inner regions of stars. Using a technique called asteroseismology, which uses sound waves generated by turbulence on the surface of stars to determine their inner properties, the scientists found that the fusion-powered cores of red giants, stars that are evolved versions of our sun, are strongly magnetized. The findings will help astronomers better understand the evolution of stars.

Ocean heat content reveals secrets of fish migration behaviors
Researchers at the University of Miami Rosenstiel School of Marine and Atmospheric Science developed a new method to estimate fish movements using ocean heat content images, a dataset commonly used in hurricane intensity forecasting. With Atlantic tarpon as the messenger, this is the first study to quantitatively show that large migratory fishes, such as yellowfin and bluefin tunas, blue and white marlin, and sailfish have affinities for ocean fronts and eddies.

Beavers take a chunk out of nitrogen in Northeast rivers
Beavers, once valued for their fur, may soon have more appreciation in the Northeastern United States. There they are helping prevent harmful levels of nitrogen from reaching the area's vulnerable estuaries. By creating ponds that slow down the movement of water, they aid in removing nitrogen from the water.

Caltech scientists find cells rhythmically regulate their genes
Even in a calm, unchanging environment, cells are not static. Among other actions, cells activate and then deactivate some types of transcription factors -- proteins that control the expression of genes -- in unpredictable and intermittent pulses. A Caltech study shows that pulsing can allow two proteins to interact in a rhythmic fashion that allows them to control genes. These rhythms may underlie core processes in the cells of organisms across the kingdoms of life.

Study in mice shows how brain ignores distractions
In a study of mice, scientists discovered that a brain region called the thalamus may be critical for filtering out distractions. The study, published in Nature and partially funded by the National Institutes of Health, paves the way to understanding how defects in the thalamus might underlie symptoms seen in patients with autism, attention deficit hyperactivity disorder (ADHD), and schizophrenia.

Analysts see nations' misuse of 'rational use' when it comes to fishing rights
The term 'rational use,' as applied to fishing rights in Antarctic waters, has been misused by certain countries, an analysis by a team of researchers has concluded. Its work, which comes ahead of the 34th international convention where these matters are negotiated, posits that some nations mistakenly see the term as a license for unrestricted fishing.
