Images made by NASA’s 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

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

A study of a common wild mouse by two University of Illinois at Chicago biologists has found evidence of dramatic evolutionary change in a span of just 150 years, suggesting genetic evolution can occur a lot faster than many had thought possible.
The findings are the first report of such quick evolution in a mammal and appear in the May 22 issue of the journal Nature.

A microbiological survey of households finds little significant difference in levels of bacteria or antibiotic resistance between those that use antibacterial cleaning products and those who do not. Researchers from Tufts University School of Medicine report their findings today at the 103rd General Meeting of the American Society for Microbiology.

“The use of biocides, also called antibacterials, has become increasingly popular for regular household use. While originally developed to contr
