... and this is the experience the lucky candidates are having!

An illness that has been decimating US honeybees for more than three years probably isn't caused by a single virus, but by multiple viruses that wear down the bees' ability to produce proteins that can guard them against infection, according to a new study.

Scientists have discovered the amino acid glycine, a critical component of all living things, hiding in samples from the comet Wild 2. It's the first

Scientists are playing an exotic game of pitch and catch between Illinois and Minnesota. Their catcher's mitt is solid iron, weighs 5,500 tons, and is parked in northern Minnesota in an abandoned iron mine. With millions of dollars from the federal stimulus package, construction crews are now bui...

A single mega-colony of ants has colonised much of the world, scientists have discovered.

A team of scientists from the California Institute of Technology, Princeton, Drexel University, and the Massachusetts Institute of Technology have formed the first professional scientific organization based entirely in virtual worlds. Meta Institute for Computational Astrophysics (MICA) conducts professional seminars and popular lectures, among other events, for its growing membership.

Scientists at UW-Madison have reprogrammed skin cells and turned them into different kinds of retinal cells, raising hopes for treating disorders that rob millions of their vision.

Researchers demonstrate a role for the brain's connective tissue in learning a new task

Researchers have regressed human stem cells to an embryonic state using just a single transcription factor, as opposed to the four factors previously needed to induce pluripotency in human cells, according to a study published online today (August 28) in Nature.

Entropy can decrease, according to a new proposal - but the process would destroy any evidence of its existence, and erase any memory an observer might have of it. It sounds like the plot to a weird sci-fi movie, but the idea has recently been suggested by theoretical physicist Lorenzo Maccone, currently a visiting scientist at MIT, in an attempt to solve a longstanding paradox in physics.

Fifteen years since the last discovery of its kind, scientists have finally identified a new set of genes that may contribute to Alzheimer's disease. The three new genes, known as clusterin, complement receptor 1 (CR1) and PICALM, were uncovered by two separate research groups.

Dog owners often compare their pets to toddlers; many even treat their pooches like kids. It's easy to label such comparisons sentimental. But a new study suggests that the owners are right. A team of scientists has discovered that dogs behave surprisingly like 10-month-old infants on a classic psychological test--though there is one important difference.

Have a friend remove an object from a room you know well--say, a napkin holder from your kitchen--and then see if you can guess what he's taken away. Even if you don't know the answer, your eyes will unconsciously fixate on the stretch of countertop next to the toaster where the holder usually sits. Remembering what goes where in your kitchen is called relational memory, and now scientists have shown that your unknowing stare may be a sign that your brain remembers even when you don't.

Scientists may have discovered a way to glean information about stored memories by tracking patterns of eye movements, even when an individual is unable (or perhaps even unwilling) to report what they remember.

What happens to fat left over from a liposuction procedure? Brad Pitt might choose to turn it in to soap, but scientists at Stanford University have figured out a surprising alternative: stem cells.

The conventional view of human evolution and how early man colonised the world has been thrown into doubt by a series of stunning palaeontological discoveries suggesting that Africa was not the sole cradle of humankind. Scientists have found a handful of ancient human skulls at an archaeological site two hours from the Georgian capital, Tbilisi, that suggest a Eurasian chapter in the long evolutionary story of man.
