Mechanism That Explains How Cancer Enzyme Winds Up On Ends Of Chromosomes Found

Researchers have shown a mechanism that explains how two essential components of human telomerase -- normally active only in early prenatal development but turned back on during cancer growth -- are "recruited" from distinct sites in the cell to the telomere, an area at the end of a chromosome that normally protects it from destruction.

Non-parental Care Of Infants Tied To Unfavorable Feeding Practices

With more new mothers in the workplace than ever before, there has been a corresponding increase in the number of child care facilities in the United States. At the same time, data from a variety of sources point to a growing prevalence of overweight infants and toddlers. Is there a connection? According to a new study, child care factors and feeding practices may indeed play a role.

Skyscraper Run-Ups: What It Takes To Be An Extreme Athlete

Scientists have recently become interested in the biomechanics of a very unusual activity: skyscraper run-ups. Competitors in this extreme sport ascend the steps inside the world's tallest buildings, the winners often scaling thousands of steps in just a few minutes. New research has shed light on the metabolic profile of athletes, as well as having a potential impact on studies of aging.

Will Our Future Brains Be Smaller?

New research has shown that the evolutionary pressures arising from the older, faster, but less accurate, part of the brain may have shaped the more recent development of the slower-acting but more precise cortex, found in humans and higher animals.

Controlling The Size Of Nanoclusters: First Step In Making New Catalysts To Control Polllution

Researchers have developed a new instrument that allows them to control the size of nanoclusters -- groups of 10 to 100 atoms -- with atomic precision. They created a model nanocatalyst of molybdenum sulfide, the first step in developing the next generation of materials to be used in hydrodesulfurization, a process that removes sulfur from natural gas and petroleum products to reduce pollution.

Sign of Katrina fatigue? Storm memorial delayed (AP)

Patsy Dupart, 58, the daughter of the Rev. Lonnie Garrison, a longtime pastor at Pilgrim Progress Missionary Baptist Church in New Orleans who died in the aftermath of Hurricane Katrina, stands outside of the site for the Katrina Memorial in New Orleans, Wednesday, July 2, 2008. Nine months after the land was designated to become a memorial to the storm's estimated 1,600 fatalities, what could have been an inspiring focal point for New Orleans has dissolved into a project that is forgotten, frustrated and delayed — much like the Katrina recovery itself. (AP Photo/Cheryl Gerber)AP - Between acres of aboveground tombs that are this marshy city's way to inter the dead, there is a strip of land that is an empty tribute to the victims of Hurricane Katrina.
