Researchers have made synthetic lipids called pseudoceramides that are involved in skin cell growth and could be used in treating skin diseases in which skin cells grow abnormally.

Ceramides are lipids found in the outermost skin layer called the stratum corneum, which is made of dead skin cells and mainly serves as a physical barrier. Ceramides' main biological function is to control how skin cells grow and differentiate - a process through which skin cells become specialized.

Yes, last week science said Song Debunked: Breaking Up Actually Not So Hard To Do but it's a new week and this is a different study.

They use the same song example, though.

Dr. Bronwen Lichtenstein, UA assistant professor of criminal justice who specializes in women’s issues, recently completed a study of the health risks women over age 35 faced when they returned to the dating scene after the breakup of a long-term relationship.

Lichtenstein was investigating the theory that after an older woman leaves a long-term relationship she may make risky dating choices.

A study about predicting the outcome of actual conflicts found that the forecasts of experts are little better than those of novices, according to a new study.

When presented with actual crises, such as a disguised version of a 1970s border dispute between Iraq and Syria and an unfolding dispute between football players and management, experts were able to forecast the decisions the parties made in only 32% of the cases, little better than the 29% scored by undergraduate students. Chance guesses at the outcomes would be right 28% of the time.

Kesten C. Green of Monash University in Australia says, “Political leaders in the West are pondering how best to deal with the threat of the Iranian government’s nuclear ambitions.

Twenty-two years of dedicated research has finally resulted in success, reports a British team headed by Steven V. Ley at the University of Cambridge. They have created the first synthesis of azadirachtin, a natural compound that stops predatory insects from feeding.

Plants have a variety of defense mechanisms to deter insect attack. One such compound is azadirachtin, which was first isolated from the neem tree (also known as the Indian lilac) in 1968. The name of this natural product is derived from the botanical name of the plant, Azadiracta indica. Azadirachtin is a highly active substance that inhibits the development of the larvae of a broad spectrum of destructive insects but is harmless to mammals and beneficial insects, such as bees and ladybugs.

Six American high-school students took the top honors in the 2007 International Linguistics Olympiad in St. Petersburg, Russia earlier this month. This year was the first time a delegation represented the United States at the annual competition. Their victory brings a new focus on computational linguistics.

This year's International Olympiad featured 15 teams representing 9 different countries, including the Netherlands, Russia and Spain. Competitors were given problem sets consisting of sentences in languages most people are not familiar with, including: Tatar; Georgian; a language spoken by indigenous people in Bolivia called Movima; the Papua New Guinean language Ndom; Hawaiian; Turkish; and their English translations.

Italians, Irish and European Jews were all once considered 'non-white' by the standards of their day but that's hardly the case now - and certainly not the case with the descendants of those immigrants.

But a new study on Latino immigrants finds that, in contrast to past generations of European immigrants, a significant share of second-and-third-generation Latino-Americans still identify with a Latino racial category.

Joseph Michael, a UC doctoral student in the Department of Sociology and a researcher at the National Opinion Research Center at the University of Chicago, and Jeffrey Timberlake, University of Cincinnati assistant professor of sociology, are examining how the immigration of Latinos to the United States compares to the earlier European immigration waves of white ethnic

Cocaine abuse in the U.S. is widespread, with nearly 35 million Americans reporting having ever tried cocaine and an estimated 7.3 million users, including 15 percent of young adults ages 18 to 25, according to the National Institute on Drug Abuse.

Life-threatening emergencies related to cocaine use include sudden cardiac death, high blood pressure, stroke and acute myocardial infarctions.

UT Southwestern Medical Center researchers have discovered a treatment that counteracts the effects of cocaine on the human cardiovascular system, including lowering the elevated heart rate and blood pressure often found in cocaine users.

Researchers at Sandia National Laboratories in Albuquerque, N.M. and Livermore, Calif., are part of a Defense Advanced Research Projects Agency (DARPA) -funded team led by UOP, LLC, a Honeywell company, looking at the production of military Jet Propellant 8 (JP-8) fuel based on the use of renewable biomass oil crop feedstocks, including microalgae.

The goal of the 18-month effort, which is backed by a $6.7 million project award from DARPA, is to develop and commercialize a process to produce the Jet Propellant 8 (JP-8) fuel used by U. S.

Alcohol and smoking can be harmful, if not deadly. While the desire for these substances can be due to environmental cues, genomic factors also play an important role. The etiology of these desires is multifactorial and a result of complex interactions with the environment. Adoption and twin studies have shown that the use of these substances is likely to be inherited. Such studies have provided evidence that one’s sex can influence the genetic factors for alcohol and tobacco use.

In an attempt to find the genomic determinants underlying alcohol and tobacco use, researchers examined 120 families (approximately 900 individuals). The researchers identified an area relating to alcohol and tobacco use on chromosome 1. They found another area relating to alcohol on chromosome 3.

Oregon Health & Science University researchers have figured out how to turn a mouse into a factory for human liver cells that can be used to test how pharmaceuticals are metabolized.

The technique could soon become the gold standard not only for examining drug metabolism in the liver, which helps scientists determine a drug's toxicity.
