Playing tag with sugars in the cornfield
Grasses and crops such as maize attach sugars to chemical defenses called benzoxazinoids to protect themselves from being poisoned by their own protective agents. Then, when an insect starts feeding, a plant enzyme removes the sugar to deploy the active toxin. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now discovered why this defensive strategy fails to work against Spodoptera larvae. Armyworms deactivate the maize chemical defense by reattaching the sugar in the opposite configuration.

Syracuse's new cooling system heats up physics research
A physicist in Syracuse University's College of Arts and Sciences has received a major grant to support ongoing work in quantum information science. Britton Plourde, associate professor of physics, is the recipient of a $230,000 Defense University Research Instrumentation Program award from the Army Research Office. The award enables him to acquire a cryogen-free adiabatic demagnetization refrigerator for the College's Department of Physics.

'Skin-like' device monitors cardiovascular and skin health
A new wearable medical device can quickly alert a person if they are having cardiovascular trouble or if it's simply time to put on some skin moisturizer, reports a Northwestern University and University of Illinois study. The small device can be placed directly on the skin and worn 24/7 for around-the-clock health monitoring. The technology uses thousands of tiny liquid crystals on a flexible substrate to sense heat. When the device turns color, the wearer knows something is awry.

Study: Biochar alters water flow to improve sand and clay
New research from Rice University and Colorado College could help settle questions about one of biochar's biggest benefits -- the seemingly contradictory ability to make clay soils drain faster and sandy soils drain slower. The research about the popular soil amendment appears this week in PLOS ONE.

Alzheimer's patients can still feel the emotion long after the memories have vanished
A new University of Iowa study further supports an inescapable message: caregivers have a profound influence -- good or bad -- on the emotional state of individuals with Alzheimer's disease. Patients may not remember a recent visit by a loved one or having been neglected by staff at a nursing home, but those actions can have a lasting impact on how they feel.

Most stars are born in clusters, some leave 'home'
New modeling studies demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. These protostars are born out of rotating clouds of dust and gas, which act as nurseries for star formation. Rare clusters of multiple protostars remain stable and mature into multi-star systems. The unstable ones will eject stars until they achieve stability and end up as single or binary stars.

Water-quality trading can reduce river pollution
Allowing polluters to buy, sell or trade water-quality credits will reduce pollution in rivers and estuaries faster and at lower cost than requiring them to meet compliance costs on their own, a Duke-led study finds. Establishing trading markets at a river-basin scale and allowing interstate trades will yield optimal results, but regulators shouldn't let uncertainties over details bog down a program's launch, since trading at any scale will yield gains over no trading at all.

Recreating the stripe patterns found in animals by engineering synthetic gene networks
Researchers at the CRG try to understand how networks of genes work together to create specific patterns like stripes. They have gone beyond studying individual networks and have created computational and synthetic mechanisms for a whole 'design space' of networks in the bacteria Escherichia coli. The system proves to be more efficient and powerful than building networks one-by-one, and its results have been published in the journal Nature Communications.

Could suburban sprawl be good for segregation?
Racially and economically mixed cities are more likely to stay integrated if the density of households stays low, finds a new analysis of a now-famous model of segregation. By simulating the movement of families between neighborhoods in a virtual 'city,' Duke University mathematicians show that cities are more likely to become segregated along racial, ethnic or other lines when the proportion of occupied sites rises above a certain critical threshold -- as low as 25 percent.

Variability keeps the body in balance
Although the heart beats out a very familiar 'lub-dub' pattern that speeds up or slows down as our activity increases or decreases, the pattern itself isn't as regular as you might think. In fact, the amount of time between heartbeats can vary even at a 'constant' heart rate -- and that variability, doctors have found, is a good thing.
