Is warfare really an immutable part of our nature, or is it something we can overcome? Some researchers now suspect the latter

"In the study, researchers took two groups of healthy young adults. Each group completed two learning sessions. The difference was that between the first and second sessions, one group got to take a 90-minute nap. The group that got the nap improved in their ability to learn by 10 percent, while the non-napping group did 10 percent worse."

ScienceDaily (July 26, 2011) - Scientists at Rensselaer Polytechnic Institute have found that when just 10 percent of the population holds an unshakable belief, their belief will always be adopted by the majority of the society. The scientists, who are members of the Social Cognitive Networks Academic Research Center (SCNARC) at Rensselaer, used computational and analytical methods to discover the tipping point where a minority belief becomes the majority opinion. The finding has implications for the study and influence of societal interactions ranging from the spread of innovations to the movement of political ideals.

ScienceDaily (July 27, 2011) - Using a measurement of the clustering of the galaxies surveyed, plus other information derived from observations of the early universe, researchers have measured the Hubble constant with an uncertainly of less than 5 percent. The new work draws on data from a survey of more than 125,000 galaxies.

ScienceDaily (July 18, 2011) - Researchers from Texas A&M University have returned from a trip to examine the scope and size of this year's "dead zone" in the Gulf of Mexico and have measured it currently to be about 3,300 square miles, or roughly the size of Delaware and Rhode Island combined, but some researchers anticipate it becoming much larger.

ScienceDaily (July 28, 2011) - The human brain is the most complex of all organs, containing billions of neurons with their corresponding projections, all woven together in a highly complex, three-dimensional web. To date, mapping this vast network posed a practically insurmountable challenge to scientists. Now, however, a research team from the Heidelberg-based Max Planck Institute for Medical Research has developed a method for tackling the mammoth task. Using two new computer programs, KNOSSOS and RESCOP, a group of over 70 students mapped a network of more than 100 neurons -- and they did so faster and more accurately than with previous methods.

What is cancer? Everyone knows that it is a terrifying disease and has some ideas about a mass of cells that grow uncontrollably but I get the feeling that many people don't quite understand how it actually happens.

International Stem Cell Corporation (ISCO) applauds the recent announcement by doctors at Sweden's Karolinska University Hospital on the creation of the world's first artificial trachea; ISCO would like our followers to understand that the concept of growing cells on a scaffold to treat diseases is showing success in our own research as exemplified by the following: 1) Collaboration with Cytograft in growing artificial blood vessels for treatment of lower limb ischemia.

"(Medical Xpress) -- Researchers from Japan recently published a paper in PLoS One describing their successful growth and transplantation of new teeth created from the stem cells of mice."

ScienceDaily (July 10, 2011) - University of Toronto researchers have derived inspiration from the photosynthetic apparatus in plants to engineer a new generation of nanomaterials that control and direct the energy absorbed from light.

ScienceDaily (July 11, 2011) - Researchers at Columbia Engineering School have built optical nanostructures that enable them to engineer the index of refraction and fully control light dispersion.

ScienceDaily (July 5, 2011) - Have you heard the saying "You only remember what you want to remember"? Now there is evidence that it may well be correct. New research from Lund University in Sweden shows that we can train ourselves to forget things.

A new study of twins released online on Monday marked an important shift in thinking about the causes of autism.

Drury, a geneticist, is a pioneer in new research exploring the biological impacts of early adversity on children. She is the first scientist to show that extreme stress in infancy can biologically age a child by shortening the tips of chromosomes, known as telomeres. These caps keep chromosomes from shrinking when cells replicate. Shorter telomeres are linked to higher risks for heart disease, cognitive decline, diabetes and mental illness in adults.

According to Mahendra Trivedi, nervous breakdown is not a regenerative term. It's not an infection without anybody else. It is simply an allegorical statement used by a common individual to clarify a larger issue.
