Dentists and their patients will soon benefit from a tiny new high-resolution X-ray camera. A Swedish company has adapted an advanced technique used for miniaturising space hardware to make a visit to the dentist a little more comfortable.
The researchers have discovered that the different behaviour of the gene in each plant is linked to one amino acid. Although the genes look very similar, the proteins they encode don't always have this amino acid.
new polymer, “conjugated polyelectrolyte (CPE) with an arylene-ethynylene repeat-unit structure,” to kill antibiotic-resistant Staphylococcus aureus bacteria – S. aureus is responsible for about 19,000 deaths every year in the U.S. alone.
Casein is already used in some adhesives and paper coatings, but it lacks strength and is water-soluble. The small amount of clay in the foam gives the casein the needed water resistance, while the addition of a biocompatible agent called glyceraldeh
Moreover, the system is concealed in a shaft, minimizing the impact on the landscape and waterways. There are thousands of locations in Europe where such power plants would be viable, in addition to regions throughout the world
Protein tougher than metal could be used to print out body armor
Researchers at Fermilab are building a “holometer” so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension
The scientists argue that when researchers are developing new ways of controlling malarial mosquitoes, for example by creating new insecticides or trying to interfere with their ability to reproduce, they need to make sure that they are effective in
Scientists from University College London studied thousands of over-50s for the English Longitudinal Study of Aging and found that wealthier participants had higher levels of the life-lengthening hormone DHEAS.
The capillary forming process begins with pieces of thin metal film, which serve as both catalyst and template, being laid down on a silicon wafer. These pieces of film have various shapes, which will determine the form of the finished nanotube struc
Any scientist can tell you how people catch fire in the movies. Only our columnist sets himself ablaze
he electrowetting effect controls the contact angle of a liquid on a hydrophobic surface through the application of an electric field. With two immiscible fluids in a transparent cell, they can actively control the contact angle along the fluid-fluid
In this research, a team led by Cedric Dicko of the University of Oxford has for the first time studied the production of pure silk, extracted in small quantities from silk worms. Using a series of small angle neutron-scattering experiments at the In
The rest of the world is trying to find alternatives to these crucial materials.
Unlike nearly every mammal that has seven vertebrae in its neck no matter how long or short its neck, sloths stand out as oddballs with up to 10. Now it turns out sloths are part of the fold (sort of) — what seem like extra neck vertebrae actually co
Engineers at MIT have now used a new microchip technology to rapidly test potential drugs on tiny worms called C. elegans, which are often used in studies of the nervous system. Using the new technology, associate professor Mehmet Fatih Yanik and his
he added: “The important thing about our study is that it gives a historical perspective to this disease. We can make very clear statements on the cancer rates in societies because we have a full overview. We have looked at millennia, not one hundred
Essentially, he took effects that are considered valid and reliable in psychology - studying improves memory, priming facilitates response times - and simply reversed their chronological order.
A Toronto-based company called Interaxon has been developing a system that allows you to manipulate surroundings with your mind. Right now the technology is fairly simple. By tracking your brainwaves with an Electroencephalograph (EEG), Interaxon’s s
Nanocomposites can also serve as “molds” for the production of porous substances. These have potential application in the areas of gas storage, catalysis, or materials separation.
Mohanram likened the new transistor's abilities to that of a water tap. "Turn it on and the water flows," he said. “Turn it off and the water stops. That's what a traditional transistor does. It's a unipolar device – it only opens and closes in
The Hoover Dam bypass bridge is a study in superlatives. The highest and longest arched concrete bridge in the Western Hemisphere. The second-highest bridge of any kind in the US and 14th in the world. The world's tallest concrete columns of their ki
Cancer is the bane of the modern world. It kills millions of people annually. Yet the strange fact is, that there is almost no trace of the insidious killer among the remains of ancient peoples.This incredible epiphany rocked researchers on their hee
Mahtab Jafari's research shows curry's main ingredient has more to offer than good flavor. It extended the lifespan of fruit flies by up to 20 percent, while improving locomotion and having tumor-prevention properties.
If just 3 percent of the dissolved minerals precipitate -- an estimate based on earlier studies -- the ocean floor would hold reserves vastly greater than those on land, Cathles said.
We expected the debris field to expand dramatically, like shrapnel flying from a hand grenade," said astronomer David Jewitt of the University of California in Los Angeles, who is a leader of the Hubble observations. "But what happened was quite th
Is nonconformity and freethinking a mental illness? According to the newest addition of the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders), it certainly is. The manual identifies a new mental illness called “oppositional defiant dis
Hydrophobic materials have all kinds of practical applications, from creating surfaces that never have to be cleaned to making supertankers and container ships glide more efficiently through the water.

Scientists recently pulled together the pieces of the world’s most powerful laser and, in a first-ever complete dry run, pulled the trigger on a peppercorn-sized pellet of nuclear fuel. In short: It worked.
