NEW YORK, March 1, 2012 – Probing the largely unexplored question of what characteristics make a leader among schooling fish, researchers have discovered that by mimicking nature, a robotic fish can transform into a leader of live ones.

WASHINGTON, March 1—As IP traffic continues to increase and the router interface rate extends beyond 100 gigabits-per-second (Gb/s), future optical networks—ones that would achieve unprecedented speeds of 1 terabit-per-second (Tb/s)—will be required to support the rapid growth of data services with different capacities and patterns on the same optical platform.

WASHINGTON, March 1—In yet another astounding application of the "wonder material" graphene, scientists at the University of California, Berkeley discovered that it makes an excellent active media for optical modulators. Graphene-based modulators are expected to significantly enhance ultrafast optical communication and computing. team will report on their findings at the Optical Fiber Communication Conference and Exhibition/National Fiber Optic Engineers Conference (OFC/NFOEC) taking place next week in Los Angeles.

Spanish consumers are defenceless against deceptive advertising broadcasted on the radio in areas that could affect their health, according to a study carried out by two lecturers at the Rey Juan Carlos University in Madrid. The project reports that this infringement of law takes place specifically in health-related advertisements.

The researchers show that the current methods oversimplify the measure by not accounting for water quality; the key measure of safety. In four of the five developing countries studied, the reduction in reported progress would be substantial. It is likely that MDG safe-water progress in other developing countries is similarly overstated.

WASHINGTON -- Almost everyone has seen the Periodic Table of the Elements, the chart gracing walls of science classrooms that shows relationships between the chemical elements that make up everything on Earth — and beyond. The American Chemical Society (ACS), the world's largest scientific society, now is offering viewers of its award-winning Bytesize Science series a tour of what may stake a claim to being the world's first and only Periodic Table table.

A novel system for processing embryos during IVF treatment has been shown to significantly improve the chances of pregnancy – by more than a quarter.

Pioneered by a Newcastle team of fertility experts at the University and within the NHS, the innovative design of interlinked incubators provides a totally enclosed and controlled environment within which every step of the IVF process can be performed.

The pecan weevil, Curculio caryae (Horn), is a major pest of pecans throughout the southeastern United States, as well as portions of Texas and Oklahoma.

Almost 80 percent of current farmland in the U.S. would have to be devoted to raising corn for ethanol production in order to meet current biofuel production targets with existing technology, a new study has found. An alternative, according to a study in ACS' journal Environmental Science & Technology, would be to convert 60 percent of existing rangeland to biofuels.

Law enforcement officials who are tasked with identifying a body based on partial skeletal remains have a new tool at their disposal. A new paper from North Carolina State University researchers details how to determine the biological sex of skeletal remains based solely on measurements of the seven tarsal bones in the feet.

Scientists at University College Dublin have discovered a new way of measuring the potential success rate of an embryo before it is transferred back into the womb during in vitro fertilisation (IVF).

According to the findings published online in the journal Fertility and Sterility, the fluid within a woman's ovaries that surrounds the egg or oocyte holds metabolic information that can improve predictions on which embryo is more likely to lead to pregnancy.

By means of cloud computing, enterprises can access scalable computing power and storage capacity. A people cloud, by contrast, supplies a scalable number of workers via the internet. It is used when non-automated tasks are executed, such as allocating images, searching information, or writing texts. The challenge is to maintain the quality of the work results on a constant high level. Now, this is achieved by a quality management system developed by KIT.

FEBRUARY 2012 -- A University of Toronto research team has developed a process to analyze the behavior of bitumen in reservoirs using a microfluidic chip, a tool commonly associated with the field of medical diagnostics. The process may reduce the cost and time of analyzing bitumen-gas interaction in heavy oil and bitumen reservoirs.

Research at the University of Liverpool, using computer models to reconstruct the jaw muscle of Tyrannosaurus rex, has suggested that the dinosaur had the most powerful bite of any living or extinct terrestrial animal.

The team artificially scaled up the skulls of a human, alligator, a juvenile T. rex, and Allosaurus to the size of an adult T. rex. In each case the bite forces increased as expected, but they did not increase to the level of the adult T. rex, suggesting that it had the most powerful bite of any terrestrial animal.

The invention of a long-lasting incandescent light bulb in the 19th century spurred on the second wave of the industrial revolution, illuminating homes, extending leisure time and bringing us to the point today where many millions of people use a whole range of devices from mood lighting to audiovisual media centers, microwave ovens to fast-freeze ice makers, and allergy-reducing vacuum cleaners to high-speed broadband connected computers in their homes without a second thought.
