Socializing with friends and family can do more than lift the spirits of elderly women -- it can improve cognition and might help prevent dementia, according to a new study. The study began in 2001 and included women at least 78 years old who were free of signs of dementia. Researchers conducted follow-up interviews between 2002 and 2005.

Can human beings rev up their intelligence quotients, or are they stuck with IQs set by their genes at birth? Until recently, nature seemed to be the clear winner over nurture. But new research suggests that at least one aspect of a person's IQ can be improved by training a certain type of memory. Source: ScienceDaily: Latest Science News | 6 Jun 2008 | 9:00 pm
For the first time, research describing a new modified luminescent worm allows scientists to measure -- in real time -- the metabolism of an entire living organism. The key behind this capacity relies in the fact that the luminescence is produced using the animal's available energy, which reflects its metabolism that, as such, can be extrapolated from measuring the emitted light.

One of the most critical processes in biology is the transcription of genetic information from DNA to messenger RNA (mRNA), which provides the blueprint for the proteins that form the machinery of life. Now, researchers have discovered new details of how the cell's major transcriptional machinery, RNA polymerase II (Pol II), functions with such exquisite precision.

A UK researcher who oversees a global effort to develop an open-source machine that 'prints' three-dimensional objects is celebrating after the prototype machine succeeded in making a set of its own printed parts. The machine, named RepRap, works a bit like a printer, but, rather than squirting ink onto paper, it puts down thin layers of molten plastic which solidify Source: ScienceDaily: Latest Science News | 6 Jun 2008 | 6:00 pm

LiveScience.com - Scientists have discovered their first icequake, if you will - a movement of a huge stream of ice in Antarctica that creates seismic waves, just like an earthquake, and can be felt hundreds of miles away.
Starting in 2001, Douglas Wiens of Washington University in St. Louis deployed seismographs around Antarctica, which detected seismic signals between that year and 2003.
"At first we didn't know where the waves were coming from, but eventually we were able to narrow down the source to the ice stream," Wiens said. ... Source: Yahoo! News: Science News | 6 Jun 2008 | 2:25 pm
