Female fruit flies sometimes choose males who are aggresive, sometimes choose males who do not fight at all, and sometimes choose males for no reason science can explain, write a team of biologists,…

Huge star streams in the outskirts of two nearby spiral galaxies have allowed astronomers to obtain a panoramic overview of ' galactic cannibalism' similar to that involving the Sagittarius dwarf…

The electric solar wind sail developed at the Finnish Meteorological Institute has moved rapidly from invention towards implementation. Electric sail propulsion might have a large impact on space…

A team of researchers from Case Western Reserve University has found that gravitational radiation—widely expected to provide “smoking gun” proof for a theory of the early universe known as “inflation…

Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy’s central black hole let loose a powerful flare three centuries ago. The finding…

Matter and anti-matter are believed to have been created in equal amounts when the universe came in to existence during the Big Bang, yet in the universe today there is only matter. The quest to…

Public scandals, such as Enron, Societe Generale and Global Crossing, the sub-prime mortgage problem, and the ensuing global credit crunch have led to dwindling confidence in the business world. A…

Half a century after the last earth-shattering atomic blast shook the Pacific atoll of Bikini, the corals are flourishing again. Some coral species, however, appear to be locally extinct. These are…

By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster.…

Researchers from the UAB Research Park have created the first nanomotor that is propelled by changes in temperature. A carbon nanotube is capable of transporting cargo and rotating like a…

If clumps of your hair start to fall out from a common form of baldness, a new review of existing research unfortunately offers little comfort. Patients who are afflicted by the condition known as…

A new method that uses nanotechnology to rapidly measure minute amounts of insulin is a major step toward developing the ability to assess the health of the body’s insulin-producing cells in real…

Researchers at the Duke School of Medicine apparently have solved the riddle of why cancer cells like sugar so much, and it may be a mechanism that could lead to better cancer treatments. Jonathan…

A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called “terahertz gap” has been engineered by a team of researchers from Boston College, Los…

University of Utah engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made waveguides -- the equivalent of wires -- that…

"The placenta is this amazing, complex structure and it's unique to mammals, but we've had no idea what its evolutionary origins are," says Julie Baker, PhD, assistant professor of genetics at…

Succession is one of the first things that students learn about in ecology. Each intervening stage modifies the environment in such a way that lays the groundwork for the next stage, while making the…

Each copy of the human genome consists of about 3,200,000,000 base pairs, and includes about 500,000 repeats of the LINE-1 transposable element (a LINE) and twice as many copies of Alu (a SINE), as…

The Interuniversity Microelectronics Centre(IMEC), an independent research center focusing on next generations chips and systems and enabling technologies for ambient intelligence, has developed a…

There is no question that Al Gore’s 2006 documentary "An Inconvenient Truth" is a powerful example of how scientific knowledge can be communicated to a lay audience. What continues to be debated is…
