It has long been known that tropical climate – by redistributing vast amounts of solar energy through welling hot air and the formation of towering cumulous clouds – influences weather in other parts of the world.
It remains unclear, however, how much the tropics can be affected by higher latitudes.
Now, with the help of a sophisticated computer model, scientists at the University of Wisconsin-Madison have shown that vast atmospheric “bridges” and oceanic “tunnels,” created by overturn
An innovative medical discovery that has the potential to vastly improve the lives of people suffering from coronary artery disease was implanted today in the first human patient. The antibody coated stent, developed by Dr. Michael Kutryk, a cardiologist and clinician scientist with St. Michaels Hospital and assistant professor, University of Toronto, was implanted into the first human patient at Thoraxcenter, University Hospital Rotterdam in Holland. The procedure was transmitted via a live fe
An enzyme crucial to formation of Alzheimers plaques and tangles may hold promise as a target for future medications, suggest studies in mice and cells. By blocking the enzyme, lithium stems the accumulation of beta amyloid, which forms Alzheimers plaques, scientists funded by the National Institutes of Health (NIH) report in the May 22, 2003 Nature. Inhibiting the enzyme, glycogen synthase kinase – 3 alpha (GSK-3 alpha), also blocks formation of neurofibrilary tangles by the tau protein.
Images made by NASAs Chandra X-ray Observatory have revealed two distant cosmic construction sites buzzing with activity. This discovery shows how super massive black holes control the growth of massive galaxies in the distant universe.
X-rays were detected from vast clouds of high-energy particles around the galaxies 3C294 and 4C41.17, which are 10 and 12 billion light years from Earth, respectively. The energetic particles were left over from past explosive events that can be traced
The identification and duplication of a gene that controls production of plants outermost protective coating may allow Purdue University researchers to create crops with increased drought resistance.
Scientists cloned the gene WAX2 after they discovered a fast-wilting mutant of Arabidopsis, a commonly used experimental plant. The gene is directly associated with the synthesis of the protective layer of plants, called the cuticle, and its contained waxes, according to the study publ
One-year study shows diet may be as effective and safe as conventional diets
A 3-center study led by researchers at the Weight and Eating Disorders Program of the University of Pennsylvania School of Medicine reports the results of the first controlled trial of the Atkins Diet. The Atkins Diet limits carbohydrates but permits unrestricted amounts of protein and fat. Compared to a conventional, high- carbohydrate, low-calorie approach, Atkins dieters lost twice as much weight at 3 and
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
