In recent experiments, Craig and his team found that a molecule made with a polynorbornene backbone can act as a lever to open a ring embedded within the molecule 1000 times faster than a similar ring being tugged at on a polybutadiene scaffold. The
under the influence of psychiatric drugs or withdrawing from such drugs. At least 5,000 other news stories, including school shootings, link psychiatric drugs to violent crime on the web site SSRI Stories.
The innovative production technique means that graphene can easily be integrated and fabricated on plastic sheets that have been pre-patterned with metal gates. This produces transistors in which charge carriers can move extremely fast and in which e
Even casual divers know that diving too deep, or surfacing too quickly, can cause a host of complications from sickness to seizures and even sudden death.
As for how they pass through glass, he says this is a result of a stream of ions accumulating on the outside of a glass window and the resulting electric field on the other side excites air molecules to form a ball discharge.
Carbon nanotubes, miniscule pipes of rolled up carbon atoms, have amazing properties that have taken the world by storm.
The U.S. military is already using, or fast developing, a wide range of technologies meant to give troops what California Polytechnic State University researcher Patrick Lin calls “mutant powers.” Greater strength and endurance. Superior cognition. B
While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right.

copper can prevent horizontal transmission of genes, which has contributed to the increasing number of antibiotic-resistant infections worldwide.
While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right.
A lens coated in carbon nanotubes that converts light to sound may eventually lead to an invisible scalpel for noninvasive surgery.
In the debate over IQ vs. hard work, there's an ongoing discussion about how much perceived talent can be traced back to genetics.
developed a foam-based product that can control hemorrhaging in a patient’s intact abdominal cavity for at least one hour, based on swine injury model data. The foam is designed to be administered on the battlefield by a combat medic, and is easily r
tumour cells appear to co-opt normal cells around them, in effect “talking” them into helping the cancer set up shop in other parts of the body. The process, called metastasis, is what often makes malignancies so challenging to treat — and typica
A massive whale, some 60 feet (18 meters) long, beached itself on Wednesday morning in New York City, where, despite rescue efforts, it seemed to have little chance of survival.
In September, a team from Germany claimed to have found evidence that water-soaked grains of carbon superconduct at room temperature
Greater strength and endurance. Enhanced thinking. Better teamwork. New classes of genetic weaponry, able to subvert DNA.
Children in Fukushima are getting fatter as outdoor activities have been cut in the area due to radiation fears after last year’s nuclear disaster, a Japanese government report said Tuesday.
Former US president George H.W. Bush celebrated Christmas in a Texas hospital with his family Tuesday after a series of health setbacks that have delayed his release, his spokesman said.
uous fiber-reinforced structures are difficult to shape, on the other, joining the continuous fibers with a highly viscous thermoplastic matrix material is a highly complex process. To date, there is no economically profitable production technology f
A unique spider in the Amazon rainforest was recently spotted using bits of leaves and dead insects to create larger-scale decoy spider shapes in its web, which it uses to ward off predators.
Bad Pharma is the story of the ways in which the pharmaceutical industry, with the help of regulators, doctors and academics, seeks to pervert and obfuscate the research done to test new medicines.
The Chinese government is rapidly building a bigger, more sophisticated military. Here’s what they have, what they want, and what it means for the U.S.
Athletes in the U.S. suffer 3.8 million sports-related concussions each year. While helmet makers dither with small improvements, Swedish scientists have built something that could protect us all.
A Microsoft Research project offloads data and calculations to save battery life.
The chemical-sniffing setup will send data to the Web so doctors and patients can get a better sense of what causes attacks.
Photonic crystals of tungsten emit visible light but without the same wasteful emission of infrared, say researchers aiming to reinvent the light bulb
Devices from two startups could be used to treat people with anxiety disorders—and one of the devices may eventually diagnose pain.
Researchers describe a way to make solar cells that can be applied like stickers to different surfaces, broadening applications.
