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
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
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
Ultracold experiment opens door for basic studies in quantum computing
Physicists at Rice University have completed the first real-time measurement of individual electrons, creating an experimental method that for the first time allows scientists to probe the dynamic interactions between the smallest atomic particles.
The research, which appears in the May 22 issue of the journal Nature, is important for researchers developing quantum computers, a revolutionary type of compu
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
There are many mysterious objects seen in the night sky which are not really well understood. For example, astronomers are puzzled by the “jets” emerging from planetary nebulae. However, the S-shaped jet from Henize 3-1475 is the most perplexing of all.
“Jets” are long outflows of fast-moving gas found near many objects in the Universe, such as around young stars, or coming from black holes, neutron stars, and planetary nebulae, for example. The NASA/ESA Hubble Space Telescope has imaged th
