What happens when you combine 200 liters of Diet Coke and over 500 Mentos mints? It's amazing and completely insane.
Canadian scientists said they have created the first device able to re-grow teeth and bones. Researchers filed patents earlier this month in the US for the tool based on low-intensity pulsed ultrasound technology after testing it on a dozen dental pa
An asteroid possibly as large as a half-mile or more in diameter is rapidly approaching the Earth. There is no need for concern, for no collision is in the offing, but the space rock will make an exceptionally close approach to our planet early on M
Researchers said an earlier survey had led them to suspect they might find a rich, unexplored ecosystem in the Olympic Coast National Marine Sanctuary. Today the NOAA-led project released several photographs returned by a remotely operated vehicle fr
Researchers scouring swamps in the heart of Borneo island have discovered a venomous species of snake that can change its skin color, the conservation group WWF announced. The ability to change skin color is known in some reptiles, such as the cha
Cell phone emissions excite the part of the brain cortex nearest to the phone, but it is not clear if these effects are harmful, Italian researchers reported. Adds to a growing body of research about mobile phones, their possible effects on the brain
A uniform neural net of brain cells—a brain chip—has been created by a team of scientists lead by Yael Hanein of Tel Aviv University in Israel. 100-micrometer-wide bundles of nanotubes were used to get the rat neurons to form regular patterns on a
A raised eyebrow, quizzical look or a nod of the head are just a few of the facial expressions computers could soon be using to read people's minds. An "emotionally aware" computer being developed by British and American scientists w
Scientists have found 136-million-year-old piece of amber encasing pieces of web and trapped insects that helps fill in the gaps of the origin of orb webs. The finding also indicates predatory spiders likely played a role in the evolution of flying i
"The idea is to generate a clash between particles similar to what happened a thousandth of a second after the Big Bang and see what it could tell us about the standard model of matter." [It tells us the model isn't very good.]
For one type of orchid in China, procreating is a lonely affair. Rather than depending on insects or even the wind for pollination, scientists have discovered that the orchid Holcoglossum amesianum actually fertilizes itself, The orchid de
It's one of the greatest challenges for robotics engineers: Building a machine that actually walks like one of us. So far, most attempts have come off as, well, robotic. Scientists in the field of biologically inspired design are looking at na
Scientists have used stem cells and a soup of nerve-friendly chemicals to not just bridge a damaged spinal cord but actually regrow the circuitry needed to move a muscle, helping partially paralyzed rats walk.
The rapidly advancing world of regenerative medicine just got wilder as a team of researchers has reported a better technique for growing starter arteries for people with vascular disease who need replacements. The synthetic blood vessels cou
Scientists has succeeded for the first time in creating patches of substitute tissue that can conduct the electricity needed to pump the heart. The idea is to surgically implant tissue created from a patient's own cells to fix faulty electric
As if the blueprint for life wasn't busy enough, nanotech researchers are putting DNA to work in tiny mechanical devices and as templates for electronic circuits. Recent DNA constructions include microscopic patterns, tiny gears and a molecula
Antarctic waters hover just above freezing, but that doesn't stop fish from prospering in the chilly depths. The resilient fish—known as Antarctic notothenioids—keep from freezing solid thanks to a special "antifreeze protein" t
Natural killer cells form the body's front line of defense. When viruses and cancers attack, the cells keep the invaders at bay while the rest of the immune system prepares. Unlike our other immune cells, natural killer cells are always at the
Norway began construction of a "doomsday vault", a vast top-security seed bank in a mountain near the North Pole to ensure food supplies in the event of environmental catastrophe or nuclear war.
If there was a prize for biggest sperm in nature, it would go to Drosophila bifurca, a tiny fruit fly whose coiled sperm would measure more than 2 inches long if straightened out. That's 1,000 times longer than an average human sperm.
On the sun-splashed Caribbean island of St. Kitts, Yale University researchers are injecting millions of human brain cells into the heads of monkeys afflicted with Parkinson's disease.
Gritty rats and mice living in sewers and farms seem to have healthier immune systems than their squeaky clean cousins that frolic in cushy antiseptic labs, two studies indicate. The lesson for humans: Clean living may make us sick.
When scientists wanted to find the best way to collect water, they looked to the dime-sized Namib Desert beetle. Engineers from the MIT have developed some "biomimicry" material after reading about the insect's water-catching tactics
The first pictures showing a live specimen of a rodent species once thought to have been extinct for 11 million years have been taken by a retired Florida State University professor and a Thai wildlife biologist. They took video and still photogra
He was a millionaire who dreamed of saving humanity using the sperm of geniuses. But what became of Robert Klark Graham's master plan?
Separating the layers of sediment from an ancient lake was like turning the pages of a book to get a glimpse of life in the time of dinosaurs. "A world lost for more than 100 million years was being revealed to us," said Hai-lu You of the C
The northern polar cap of Mars sprawls across the top of the Red Planet for roughly 620 miles. At thickest, the cap piles up about 9,000 feet high, but becomes thinner toward its serrated edges, where deep canyons and smaller troughs carve a spiralin
A gene named after the mythical Celtic land of the ever young could help explain how to reprogram adult cells into embryonic stem cells to treat diseases. A gene they called Nanog helped to transform adult mouse cells into embryonic stem cells after
Walking upside-down requires a careful balance of adhesion and weight, and specialized trekking tools to combat the constant tug of gravity. Each fly foot has two fat footpads that give the insect plenty of surface area with which to cling. The ad
A legally blind poet at the Massachusetts Institute of Technology has designed a "seeing machine" that allows people with limited vision to see faces of friends, read or study the layouts of buildings they intend to visit.
