Mechanism of black cohosh versus hot flashes revealed
The natural herb black cohosh is commonly used by women to treat menopausal symptoms such as hot flashes, but the molecular mechanisms underlying its action have eluded scientists - until now.   view more (2006-12-26)

Black cohosh does not relieve menopausal hot flashes, Group Health researchers find
The popular herbal supplement black cohosh does not relieve hot flashes among women going through menopause, according to a study by researchers from Group Health Cooperative, a Seattle-based health care system.   view more (2006-12-19)

UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and... view more (2001-01-19)

Why Nanolayers Buckle when Microbeams Bend
High-strength, ultra-light and elastic carbon materials are commonly used in high-performance sports goods and modern aerospace technology-for example in tennis rackets, racing tyres, heat shields and even guitars.   view more (2005-12-16)

Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times... view more (1999-06-08)

The critical importance of mangroves to ocean life
Mangroves, the backbone of the tropical ocean coastlines, are far more important to the global ocean's biosphere than previously thought.   view more (2006-02-28)

UCR Researchers Grow Bone Cells on Carbon Nanotubes
Researchers at the University of California, Riverside have published findings that show, for the first time, that bone cells can grow and proliferate on a scaffold of carbon nanotubes.   view more (2006-03-16)

Sprats With Polonium
There are many radioactive elements in the world. For example, natural element polonium has 33 radioactive isotopes. Fortunately, only one isotope, 210Po, has a relatively long (138.4 days) half-life period. This isotope appears in the atmosphere as a result of radon decay, sinks to oceans and... view more (2002-07-19)

Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate.   view more (2008-09-12)

Method could help carbon nanotubes become commercially viable
Carbon nanotubes are intriguing new materials which have been highly touted for their exceptional mechanical, thermal, optical and electrical properties.   view more (2006-10-05)

Climate change creates dramatic decline in red-winged black bird population
Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972.   view more (2006-11-14)

NJIT researchers seed, heat and grow carbon nanotubes in long tubing
In less than 20 minutes, researchers at New Jersey Institute of Technology (NJIT) can now seed, heat and grow carbon nanotubes in 10-foot-long, hollow thin steel tubing.   view more (2006-08-07)

Kentucky Geological Survey involved in global climate change research
Researchers at the Kentucky Geological Survey are studying options to reduce the amount of carbon dioxide emitted into the atmosphere. Carbon dioxide is produced by the burning of coal, gasoline, and natural gas and has been linked to global warming.   view more (2005-07-15)

Carbon monoxide may help prevent debilitating pregnancy condition
New findings by Queen's University researchers suggest that administering low doses of carbon monoxide to pregnant women may help prevent the potentially damaging effects to mother and baby of pre-eclampsia.   view more (2006-09-06)

CBEN: Buckyball aggregates are soluble, antibacterial
In some of the first research to probe how buckyballs will interact with natural ecosystems, Rice University's Center for Biological and Environmental Nanotechnology finds that the molecules spontaneously clump together upon contact with water, forming nanoparticles that are both soluble and toxic... view more (2005-06-23)

Add nanotubes and stir - with the right force
Polymer scientists at the National Institute of Standards and Technology have some stirring results to share with researchers and companies developing new, advanced composite materials with carbon nanotubes-mix carefully.   view more (2006-07-24)

Alcoholics underestimate the risk of bleeding
Gastrointestinal bleeding can be fatal - something which is not known to many alcoholics.   view more (2008-02-19)

Astronomers detect stellar ashes at dawn of time
Using a powerful instrument on a telescope in Hawaii, UK astronomers have found ashes from a generation of stars that died over 10 billion years ago. This is the first time that the tell-tale cosmic dust has been detected at such an early stage in the evolution of the universe.   view more (2002-04-10)

Uncovering Sex-Change Secrets Of The Black Sea Bass
In a former cowshed on the edge of the University of New Hampshire campus, David Berlinsky, assistant professor of zoology, peers into a big blue plastic tub.   view more (2006-04-12)

ESA steps towards a great black hole census
Astronomers using ESA's orbiting gamma-ray observatory, Integral, have taken an important step towards estimating how many black holes there are in the Universe.   view more (2006-09-08)

Study shows hibernating bears conserve more muscle strength than humans on bed rest do
A fascinating new study from the May/June 2007 issue of Physiological and Biochemical Zoology quantifiably measures the loss of strength and endurance in black bears during long periods of hibernation.   view more (2007-04-25)

Relic of life in that Martian meteorite? A fresh look
Since the mid-1990s a great debate has raged over whether organic compounds and tiny globules of carbonate minerals imbedded in the Martian meteorite Allan Hills 84001 were processed by living creatures from the Red Planet.   view more (2006-03-23)

UCR biologists unravel the genetic secrets of black widow spider silk
Biologists at the University of California, Riverside have identified the genes, and determined the DNA sequences, for two key proteins in the "dragline silk" of the black widow spider - an advance that may lead to a variety of new materials for industrial, medical and military uses.   view more (2007-06-13)
