Caught in the act! Researchers from the University of Bristol have observed mating for the first time in the microbes responsible for African sleeping sickness. This tropical disease is caused by trypanosomes, single-celled parasites that are found in the blood of those afflicted.

Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than 30 percent.
DURHAM, N.C. -- In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power.
In a new study, researchers from Duke University's Pratt School of Engineering used computational methods to identify dozens of platinum-group alloys that were previously unknown to science but could prove beneficial in a wide range of applications.
Children are likely to have stronger muscles if their mothers had a higher level of vitamin D in their body during pregnancy, according to new research from the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU) at the University of Southampton.
Low vitamin D status has been linked to reduced muscle strength in adults and children, but little is known about how variation in a mother's status during pregnancy affects her child.
SAN DIEGO – Research by the Scripps Translational Science Institute (STSI) has found that a small adhesive wireless device worn on the chest for up to two weeks does a better job detecting abnormal and potentially dangerous heart rhythms than the Holter monitor, which is typically used for 24 hours and has been the standard of care for more than 50 years.

(SACRAMENTO, Calif.) — If a picture is worth 1,000 words then a movie is worth far more, especially when it comes to diagnosing wrist problems.
UC Davis radiologists, medical physicists and orthopaedic surgeons have found a way to create "movies" of the wrist in motion using a series of brief magnetic resonance imaging scans. Called "Active MRI," the technique could be useful in diagnosing subtle changes in physiology that indicate the onset of conditions such as wrist instability.
Researchers from North Carolina State University and Johns Hopkins University have found that an increase in the use of wind power generation can make the power grid more fragile and susceptible to disruptions. But the researchers didn't just identify the problem – they have also devised a technique for coordinating wind power generation and energy storage in order to minimize the potential for such power disruptions.
Researchers Aalto University have revealed how emotions are experienced in the body.
Emotions adjust our mental and also bodily states to cope with the challenges detected in the environment. These sensations arising from the bodily changes are an important feature of our emotional experiences. For example, anxiety may be experienced as pain in the chest, whereas falling in love may trigger warm, pleasurable sensations all over the body. New research from Aalto University reveals, how emotions are literally experienced through the body.
It was recently shown that large-aperture lens antennas can be designed by using gradient-index (GRIN) metamaterials and that higher directivity and gain can be obtained than with traditional dielectric lens antennas. This provides an effective method to design high-performance lens antennas.
A team of researchers from the Department of Electrical & Computer Engineering at the National University of Singapore (NUS) Faculty of Engineering has developed a new Magnetoresistive Random Access Memory (MRAM) technology that will boost information storage in electronic systems. The innovative technology will drastically increase storage space and enhance memory which will ensure that fresh data stays intact, even in the case of a power failure. The team has already filed a US provisional patent for their technology.
Richland, Wash. -- Researchers have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. While life sciences researchers regularly use transmission electron microscopy to study wet environments, this time scientists have applied it successfully to rechargeable battery research.
Computer scientists are constantly searching for ways to squeeze ever more bandwidth from communications networks.
Now a new approach to understanding a basic concept in graph theory, known as "vertex connectivity," could ultimately lead to communications protocols — the rules that govern how digital messages are exchanged — that coax as much bandwidth as possible from networks.
The completion of the 30-day Lunar Laser Communication Demonstration or LLCD mission has revealed that the possibility of expanding broadband capabilities in space using laser communications is as bright as expected.
When a man in Israel was accused of sexually abusing his young daughter, it was hard for many people to believe — a neighbor reported seeing the girl sitting and drinking hot chocolate with her father every morning, laughing, smiling and looking relaxed. Such cases are not exceptional, however. Children react to sexual and physical abuse in unpredictable ways, making it hard to discern the clues.
