The nucleus: Not just a bag of chromosomes
... is an orchestrated process similar to the pulling apart of the chromosomes. It seems to involve the same structures and the same tiny motors. It's almost a practice run for moving the chromosomes." Wilson notes that no college textbook yet reflects current understanding of the nucleus.

If reared, by what Dr. Suomi refers to as "super moms", not only are these monkeys less likely to express these traits, but in some instances do better than normal peers who did not ha...Scientists crack the black box of coastal ecosystems

...ion. "The challenge to scientists becomes teasing apart these agents to understand their interactions," the researchers said in this article. "Humans and other animals may be affected by the same environmental insults harming amphibians. We should heed their warning."...Researchers link melanopsin gene to unexplored light detection system within the eye
...t. "Our research has led us to believe that, quite apart from regulating pupil size, the melanopsin photoreceptors may be responsible for a broad range of responses to light, including its ability to keep us awake and alert. It is also likely that these photoreceptors are responsible for resetting our inte...Food for thought: Cells dine on their own brains to stay fit and trim

...f species," Root explained. "I call it the tearing apart of communities. For example, four types of warblers feed on spruce budworm caterpillars. But the birds are shifting north. What happens when the birds no longer are present in the southern portion of their ranges, and the caterpillar population is no......1B controls a key enzyme needed to help cells pull apart at the end of mitosis, the final step in cell division. "These results clearly link FoxM1B with the failure of tissues to mend," Costa said. "And in old age, when the FoxM1B gene is essentially out of action, we see the results."...Chicken pox vaccine OK for children with kidney disease
...la vaccine for chicken pox given one to two months apart can be safe and effective in children with chronic kidney disease. The findings, reported in the January issue of Pediatric Nephrology, are critical for chronic kidney disease patients, particularly children who will eventually undergo a kidney tran...Arsenic in Bangladesh drinking wells may be linked to crop irrigation, MIT study finds
...r. They installed 17 research wells about 4 meters apart at depths ranging from 5 to 165 meters, and collected three sediment cores, determining that the sediment was typical of southern Bangladesh. They did not find peat, which has been associated with dissolved arsenic, but did find a fairly even distri...Rutgers and Albert Einstein College of Medicine researchers seek fountain of youth among the worms

The fly's ovary is an artichoke-like structure occupying most of its abdomen. The goal was to count each of the ovary's ovarioles so the researchers could localize where ...MRI technique lets researchers directly compare monkey and human brains
