"Scirus is the most comprehensive scientific research tool on the web. With over 410 million scientific items indexed at last count, it allows researchers to search for not only journal content but also scientists' homepages, courseware, pre-print server material, patents and institutional repository and website information.

"Coffee addicts have an excuse for blaming their genes. According to new research, genetic factors could explain why some people consume large amounts of caffeine. US researchers scanned genetic variations in over 40,000 individuals to search for links with high caffeine intake."

"A collaborative research project has brought the world a step closer to producing a new material on which future nanotechnology could be based. Researchers across Europe, including the UK's National Physical Laboratory (NPL), have demonstrated how an incredible material, graphene, could hold the key to the future of high-speed electronics, such as micro-chips and touchscreen technology."

"In particular, rapid swings in the density of plants and fleas indicated the food web was unstable and about to change. The idea that such early warning signals ought to exist is not new - but the researchers say this is the first time it has been demonstrated experimentally. "For a long time, ecologists thought these changes couldn't be predicted," said research leader Stephen Carpenter from the University of Wisconsin in Madison, US. "But we've now shown that they can be foreseen. The early warning is clear; it is a strong signal.""

"Todd Rider, a research scientist at the Massachusetts Institute of Technology, is developing an antiviral drug called Draco, which has proven successful against all 15 viruses to which it has been applied in lab trials with human tissue and mice. These include the common cold, H1N1 or swine flu, a polio virus, dengue fever and the notorious and fatal Ebola virus. To produce it, Mr Rider took an unusual approach, "wiring together" two natural proteins - one that detects virus entry, and another that acts as a suicide switch that kills the infected cell."

"Researchers from the University of Michigan discovered that a session of aerobic exercise increases storage of fat in muscle, which actually improves insulin sensitivity. Low insulin sensitivity, or insulin resistance, is an impaired ability of the body to take up sugar from the blood, which can lead to high blood sugar and diabetes."

"A dizzying array of research suggests alcohol can have both good and bad effects, but making sense of such studies all comes down to who you are and how much you drink. That point was driven across Tuesday with the release of a U.S. study suggesting women who consume three to six alcoholic beverages a week face a small increased risk of breast cancer, but it's not enough of a danger to stop drinking. The study in the Journal of the American Medical Association involved 105,986 nurses who were tracked for three decades."

"The onset of wrinkles, muscle wasting and cataracts has been delayed and even eliminated in mice, say researchers in the US. It was done by "flushing out" retired cells that had stopped dividing. They accumulate naturally with age. The scientists believe their findings could eventually "really have an impact" in the care of the elderly."

"The team from the French National Institute for Agricultural Research (INRA) surveyed the composition of plant species within five-metre SGS in 10 fields and found the set-aside land resulted in a "sharp decrease" in the number of weeds encroaching into the cropped area."

"Think the school you chose for your child is good? Better than that academic straggler just down the road? Think again. A new study is raising questions about the information parents commonly use to chose a school for their children, especially in provinces like Alberta and British Columbia, where families commonly shop around for an education."

"A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 meters."

Join Bill Nye as he delves into the Greatest Discoveries in Biology. This program explains how the early use of microscopes and Anton Van Leeuwenhock's accidental discovery set the stage for studying microorganisms. It explores 19th century research breakthroughs and covers cell division, sex cell division, and cell differentiation. Learn how the discovery of mitochondria has helped us understand reproduction, ancestral lines, and cancer; how cells convert sugars, fats, and proteins into energy in the Krebs Cycle; and how they communicate through neurotransmitters and hormones. Explore the process of photosynthesis and how the discovery of the ecosystem process bridged biology with physics, chemistry, and other fields of science that describe the environment.

Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem. The algorithm computes the two numbers that multiply together to form a given figure, and has until now required laboratory-sized optical computers. This kind of factoring is the basis for a wide variety of encryption schemes.

Arctic temperatures are now higher than at any time in the last 2,000 years, research reveals. Changes to the Earth's orbit drove centuries of cooling, but temperatures rose fast in the last 100 years as human greenhouse gas emissions rose. Scientists took evidence from ice cores, tree rings and lake sediments.

Created for scientists by scientists, SciVee provides synchronization tools and resources that connect science publications to media rich online video communication for scientific research communities.

The Physics Factbook™ is an encyclopedia of scientific essays written by high school students that can be used by anybody. It is an exercise in library research methods in which students are sent out in search of a measurement with the intent of having them find more than just a number with a unit. It is an ongoing project with no foreseeable end date or limits.

"Every so often a giant emerges on the stage of science, someone who transcends the narrow boundaries of a particular line of research and alters our perspective on the world. E.O. Wilson is such a man."
