Nature Of Consciousness: How Activity Of Single Neurons In Human Brain Reflect Conscious Perception
via ScienceDaily: Latest Science News by (author unknown) on February 18, 2008
Scientists have made a significant step into the understanding of conscious perception, by showing how single neurons in the human brain reacted to certain images. This line of research could lay the foundation for developing a neural prostheses which could read commands directly from the brain and transmit them to bionic devices such as a robotic arm that a patient with limited mobility could...

Bug Guts Map Brings Scientists Closer To Understanding Different Bugs' Role In The Body
via ScienceDaily: Latest Science News by (author unknown) on February 07, 2008
Scientists have made a major step towards understanding precisely which bugs in the gut are involved in which processes in the body, by mapping the different species of bugs living in seven members of the same Chinese family.

Fatty Acids Beneficial In Treatment For Dry Eye Syndrome
via ScienceDaily: Latest Science News by (author unknown) on February 14, 2008
Topical drop application of alpha-linolenic acid led to a significant decrease in clinical signs of dry eye syndrome in animal models. ALA is a fatty acid that cannot be made by the body, and must be supplied in the diet.

Web Sites Influence Users, Even When They Don't Communicate Directly
via ScienceDaily: Latest Science News by (author unknown) on February 15, 2008
Web surfers may get more than just the music, videos and news updates they were looking for when they log onto trendy next-generation sites such as Last.fm, YouTube and Digg, according to new research. Whether they know it or not, they also could be getting swayed -- toward musical genres that stretch their tastes or to video and news clips they might have overlooked without an endorsement by the...

There Is 'Design' In Nature, Biologist Argues
via ScienceDaily: Latest Science News by (author unknown) on February 16, 2008
A Brown University biologist says the best way to communicate evolution in a religious America is to acknowledge that there is indeed a "design" in living things. He says scientists should embrace the concept of "design" in a way that supports evolutionary theory. He argues that science itself, including evolutionary biology, is predicated on the idea of "design" -- the correlation of structure...

MRSA: Mathematical Modeling Offers New Approaches To Fight Dual-resistant Hospital Infections
via ScienceDaily: Latest Science News by (author unknown) on February 16, 2008
A mathematical model that looks at different strategies for curbing hospital-acquired infections suggests that antimicrobial cycling and patient isolation may be effective approaches when patients are harboring dual-resistant bacteria. In an era of "superbugs," such as methicillin-resistant Staphylococcus aureas (MRSA), this type of modeling, if used to develop policies and treatment protocols,...

Using High Efficiency Particle Air Filters May Improve Cardiovascular Health
via ScienceDaily: Latest Science News by (author unknown) on February 17, 2008
One day doctors may recommend using high efficiency particle air filters along with weight loss, smoking cessation, and exercise to improve cardiovascular health, according to researchers in Denmark. In a recent study, they found that using HEPA filters for just two days significantly improved a key measure of cardiovascular health in healthy, non-smoking elderly individuals.

... boats launched from each side of the doomed ship show a different pattern when it comes to percentage of men on board: on the port (left) side, the first few boats were only lightly loaded, and contained a large number of male passengers and crewmen. On the starboard side, where good order was maintained throughout, the boats were fully loaded -- and almost completely with women and children.

Does Socializing Make Us Smarter?
via ScienceDaily: Latest Science News by (author unknown) on February 18, 2008
Humans are social animals; we spend much of our time with others in groups. We are also wise. It is not our size, speed, or strength that distinguishes us from other mammals, but our intelligence. How might these two features -- being social and being smart -- go together? Researchers found that people who engaged in social interaction displayed higher levels of cognitive performance than the...

Immune System Protein Starves 'Staph' Bacteria, Could Lead To New Treatments
via ScienceDaily: Latest Science News by (author unknown) on February 18, 2008
Scientists have discovered that a protein inside certain immune system cells blocks the growth of "staph" bacteria by sopping up manganese and zinc. The findings support the notion that binding metals -- to starve bacteria -- is a viable therapeutic option for treating localized bacterial infections. New treatments are urgently needed to combat antibiotic-resistant forms of staph, such as MRSA.
