Chili pepper cocktail points to wide-awake surgery

Imagine an epidural or a shot of Novocain that doesn`t paralyze your legs or make you numb yet totally blocks your pain. This type of pain management is now within reach. As a result, childbirth, surgery, and trips to the dentist might be less traumatic in the future, thanks to researchers at Massachusetts General Hospital (MGH) and Harvard Medical School (HMS) who have succeeded in selectively...

Honda Develops New Automatic Transmission System for Motorcycles

Honda Motor announced that it has developed the Human-Friendly Transmission (HFT), a new automatic transmission system for motorcycles using Honda`s own infinitely variable hydraulic mechanical transmission. Easy to operate, the HFT realizes outstanding relaxed riding comfort, riding feel with direct response and excellent transmission efficiency. The HFT will be installed on the DN-01, a new...

Living fossils have hot sex

University of Utah scientists discovered a strange method of reproduction in primitive plants named cycads: The plants heat up and emit a toxic odor to drive pollen-covered insects out of male cycad cones, and then use a milder odor to draw the bugs into female cones so the plants are pollinated.

Microneedles: Flu Vaccine in Painless Skin Patches under Development

Flu vaccine delivered through painless microneedles in patches applied to the skin could soon be an alternative to delivery through hypodermic needles, according to researchers at Emory University and the Georgia Institute of Technology in Atlanta. Using new grants from the National Institutes of Health (NIH) totaling approximately $11.5 million over five years, researchers from the two...

Researchers shed light on light-emitting nanodevice

An interdisciplinary team of Cornell nanotechnology researchers has unraveled some of the fundamental physics of a material that holds promise for light-emitting, flexible semiconductors. The discovery, which involved years of perfecting a technique for building a specific type of light-emitting device, is reported in the Sept. 30 online publication of the journal Nature Materials.

Sample Non-English Domains Coming Soon

(AP) -- Sample addresses in nearly a dozen languages will be added to the Internet's central directories as early as next week, paving the way for Web surfers around the world to get online without knowing any English.

Agent that triggers immune response in plants is uncovered

Although plants lack humans' T cells and other immune-function cells to signal and fight infection, scientists have known for more than 100 years that plants still somehow signal that they have been attacked in order to trigger a plantwide resistance. Now, researchers at the Boyce Thompson Institute for Plant Research (BTI) on the Cornell campus have identified the elusive signal in the process:...

Bain Capital Agrees to Security Review

(AP) -- Bain Capital Partners will submit for a national security review its planned $2.2 billion buyout of network equipment maker 3Com Corp. to address concerns about a Chinese telecommunications company's minority stake.

EU: Roaming Cap Cuts Cell Phone Bills

(AP) -- Mobile phone bills in Europe have been slashed by as much as 60 percent since the EU placed a cap on roaming charges over the summer, the European Commission said.

Hydrothermal vents: Hot spots of microbial diversity

Thousands of new kinds of marine microbes have been discovered at two deep-sea hydrothermal vents off the Oregon coast by scientists at the MBL (Marine Biological Laboratory) and University of Washington`s Joint Institute for the Study of Atmosphere and Ocean.

Negativity is contagious, study finds

Though we may not care to admit it, what other people think about something can affect what we think about it. This is how critics become influential and why our parents` opinions about our life choices continue to matter, long after we`ve moved out. But what kind of opinions have the most effect" An important new study in the Journal of Consumer Research reveals that negative opinions cause the...

New Material May Lead To Advances In Quantum Computing

Scientists at Florida State University`s National High Magnetic Field Laboratory and the university`s Department of Chemistry and Biochemistry have introduced a new material that could be to computers of the future what silicon is to the computers of today.

Salmonid hatcheries cause 'stunning' loss of reproduction

The rearing of steelhead trout in hatcheries causes a dramatic and unexpectedly fast drop in their ability to reproduce in the wild, a new Oregon State University study shows, and raises serious questions about the wisdom of historic hatchery practices.

Simplest circadian clocks operate via orderly phosphate transfers

Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein. This phosphate pattern is influenced by two other proteins, driving phosphorylation to oscillate according to a remarkably accurate 24-hour cycle.
