First reconstitution of an epidermis from human embryonic stem cells
Stem cell research is making great strides. This is yet again illustrated by a study carried out by the I-STEM Institute, published in the Lancet on Nov. 21, 2009. The I-STEM team, directed by Marc Peschanski has just succeeded in recreating a whole epidermis from human embryonic stem cells. The goal is to one day be able to propose this unlimited resource of cells as an alternative treatment in particular for victims of third degree burns.

Unknowlingly consuming endangered tuna
New DNA barcoding from the Sackler Institute for Comparative Genomics at the American Museum of Natural History shows that nearly a third of the tuna plated in sushi restaurants was bluefin -- even if it was not labeled bluefin on the menu.

Developmental Cell
Technique finds gene regulatory sites without knowledge of regulators
A new statistical technique developed by researchers at the University of Illinois allows scientists to scan a genome for specific gene-regulatory regions without requiring prior knowledge of the relevant transcription factors. The technique has been experimentally validated in both the mouse genome and the fruit fly genome.

Environmental Health Perspectives
Cigarettes harbor many pathogenic bacteria: Study
Cigarettes are widely contaminated with bacteria, including some known to cause disease in people, concludes a new study conducted by a University of Maryland environmental health researcher and microbial ecologists at the Ecole Centrale de Lyon in France. The research team describes the study as the first to show that "cigarettes themselves could be the direct source of exposure to a wide array of potentially pathogenic microbes among smokers and other people exposed to secondhand smoke."

Anesthesiology
Surgery not linked to memory problems in older patients
For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study by School of Medicine researchers questions that assumption. In the 575 patients they studied, the investigators did not detect any long-term cognitive declines attributable to surgery.

SMOS satellite instrument comes alive
The MIRAS instrument on ESA's SMOS satellite, launched earlier this month, has been switched on and is operating normally. MIRAS will map soil moisture and ocean salinity to improve our understanding of the role these two key variables play in regulating Earth's water cycle.

Addiction
Women can quit smoking and control weight gain
Many women don't quit smoking because they are afraid of gaining weight. That's because nicotine suppresses appetite and boosts a smoker's metabolism. But a new meta-analysis shows that women who quit smoking while receiving treatment for weight control are better able to control their weight gain and are more successful at quitting cigarettes. The finding disproves clinical guidelines that say trying to diet and quit smoking at the same time will sabotage efforts to ditch cigarettes.

Science
Reference genome of maize, most important US crop, is published by team co-led by CSHL scientists
A four-year, multi-institutional effort co-led by three Cold Spring Harbor Laboratory scientists culminated today in publication of a landmark series of papers in the journal Science revealing in unprecedented detail the DNA sequence of maize. Maize, or corn, as it is commonly called by North American consumers, is one of the world's most important plants and the most valuable agricultural crop grown in the United States, representing $47 billion in annual value.

WPI researchers take aim at hard-to-treat fungal infections
Researchers at Worcester Polytechnic Institute have developed a new model system to study fungal infections. The system can be a powerful tool for screening potential drug targets for conditions like thrush, athlete's foot and vaginal yeast infections, which affect millions of people each year but are difficult to treat with existing medications. Using the new model, the researchers also identified a gene that may be a promising target for a new anti-fungal drug.

Let them eat snail
A nutritionist in Nigeria says that malnutrition and iron deficiency in schoolchildren could be reduced in her country by baking up snail pie. In a research paper to be published in the International Journal of Food Safety, Nutrition and Public Health, she explains snail is not only cheaper and more readily available than beef but contains more protein.

On the trail of a vaccine for Lyme disease: Yale researchers target tick saliva
A protein found in the saliva of ticks helps protect mice from developing Lyme disease, Yale researchers have discovered. The findings, published in the Nov. 19 issue of Cell Host & Microbe, may spur development of a new vaccine against infection from Lyme disease, which is spread through tick bites.

Asthma a significant risk factor for complications in children with H1N1
A new study on pediatric H1N1 influenza admissions has found that asthma is a significant risk factor for severe disease in children with pandemic H1N1 compared with the seasonal flu. The study, led by researchers from the Hospital for Sick Children in Toronto, Ontario, is published online today in CMAJ.

Technology Analysis & Strategic Management
Spanish biotechnology should focus on food and plant sectors to be more competitive
Spain and Latin American countries have an opportunity to take the lead in two small biotechnology sectors. Researchers from the University of Valencia, working together with the IDICHUS Foundation, have studied the productive fabric of the Spanish biotechnology industry. Their conclusion is that Spain's food and plant sectors have more clout than those in English-speaking countries.

Reflux esophagitis due to immune reaction, not acute acid burn
Contrary to current thinking, a condition called gastroesophageal reflux disease might not develop as a direct result of acidic digestive juices burning the esophagus, UT Southwestern Medical Center researchers have found in an animal study.

On the crest of wave energy
The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency and the need to be tethered to the seafloor.

New antioxidant compounds have been identified in foods such as olive oil, honey and nuts
Scientists from the University of Granada have used two new techniques, capillary electrophoresis and high resolution liquid chromatography, to enable them to identify and quantify a great part of the phenolic compounds in such foods. These compounds have a chemopreventive effect in humans and a great influence on the stability of oxidation levels of food.

Many pregnant women avoid HIV screening in Africa
"Prevention is the best cure" is a common expression, but what happens if preventative measures are not used? A large proportion of pregnant Ugandan women are going out of their way not to be HIV tested, increasing the risk of mother-to-child transmission.

Why can't some people give up cocaine?
Drug dependency is a recurrent but treatable kind of addiction. However, not all people who are drug dependent progress in the same way once they stop taking drugs. A new study shows that, in the case of cocaine, a high score on the so-called "scale of craving," an antisocial personality type and previous heroin abuse are the factors most commonly involved in people falling back into the habit.

Why Israeli rodents are more cautious than Jordanian ones
A series of studies carried out at the University of Haifa have found that rodent, reptile and ant lion species behave differently on either side of the Israel-Jordan border. "The border line, which is only a demarcation on the map, cannot contain these species, but the line does restrict humans and their diverse impact on nature," says Dr. Uri Shanas.
