Canal between ears helps alligators pinpoint sound
Alligators can accurately pinpoint the source of sounds. But it wasn't clear exactly how they did it because they lack external auditory structures. A new study shows that the alligator's ear is strongly directional because of large, air-filled channels connecting the two middle ears. This configuration is similar in birds, which have an interaural canal that increases directionality.

Natural history must reclaim its place
A group of scientists argues in the April BioScience that the study of natural history has waned in recent decades in developed countries. Declining course requirements and support for herbaria are among the documented evidence. Yet costly mistakes in policy relating to natural resources, agriculture, and health might have been avoided by paying attention to organisms' natural history, and future policies will be improved if natural history knowledge is used and expanded. New technologies offer ways to increase natural history research partnerships.

Model predicts blood glucose levels 30 minutes later
A mathematical model created by Penn State researchers can predict with more than 90 percent accuracy the blood glucose levels of individuals with type 1 diabetes up to 30 minutes in advance of imminent changes in their levels -- plenty of time to take preventative action.

Nanotube coating helps shrink mass spectrometers
Nanotechnology is advancing tools that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. When paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules. The research is detailed in a designated 'very important paper' by the journal Angewandte Chemie.

Lick's new Automated Planet Finder: First robotic telescope for planet hunters
Lick Observatory's newest telescope, the Automated Planet Finder, has been operating robotically night after night on Mt. Hamilton since January, searching nearby stars for Earth-sized planets. Its technical performance has been outstanding, making it not only the first robotic planet-finding facility but also one of the most sensitive.

Catheter innovation destroys dangerous biofilms
Duke University engineers have developed a new design that could help eliminate the threat of infection from millions of urinary catheters. The dual-channel design uses a mechanical method to uproot biofilms from their moorings so that they can easily be flushed away.

Plasma tool for destroying cancer cells
Plasma medicine is a new and rapidly developing area of medical technology. Specifically, understanding the interaction of so-called atmospheric pressure plasma jets with biological tissues could help to use them in medical practice. Under the supervision of Sylwia Ptasinska, Xu Han and colleagues conducted a quantitative and qualitative study of the different types of DNA damage induced by atmospheric pressure plasma exposure. The paper is published in European Physical Journal D.

EEG study shows how brain infers structure, rules when learning
A new study documents the brain activity underlying our strong tendency to infer a structure of context and rules when learning new tasks (even when a structure isn't valid). The findings, which revealed individual differences, shows how we try to apply task knowledge to similar situations and could inform future research on learning disabilities.

Scientists find a molecular clue to the complex mystery of auxin signaling in plants
Plants fine-tune the response of their cells to the potent plant hormone auxin by means of large families of proteins that either step on the gas or put on the brake in auxin's presence. Scientists at Washington University have learned that one of these proteins, a transcription factor, has an interaction region that, like a button magne, has a positive and negative face. Because of this domain, the protein can bind two other proteins or even chains of proteins arranged back to front.

Researchers see Kelvin wave on quantum 'tornado' for first time
A spinning tornado of very cold liquid helium obeys the laws of quantum mechanics. Sometimes, two quantum tornadoes flex into curved lines, cross over and form an X, swap ends, and then retract -- a process called reconnection. For the first time, researchers provide visual evidence that the reconnection of quantum vortexes launches Kelvin waves to quickly relax the system. Understanding turbulence in quantum fluids may offer clues to neutron stars, trapped atom systems and superconductors.

Ancient Indonesian climate shift linked to glacial cycle
Brown University researchers have compiled a detailed climate record for central Indonesia over the last 60,000 years. They find that prolonged dry spell in the region thousands of years ago correlates with the peak of the last ice age in the northern hemisphere. The data will help scientists understand the climate history of a region that wields a strong influence on global climate as a whole.
