A new species of chameleon has been discovered in a threatened forest in Tanzania. Researchers first spotted the animal while surveying monkeys in the Magombera Forest when they disturbed a twig snake eating one.

Surplus biomass from the production of flax sheaves, and generated from Brassica carinata, a yellow-flowered plant related to those which engulf fields in spring, can be used to produce bioethanol.

Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.

Scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight -- creatures that somehow manage a living in a frigid black world down to 5000 meters (three miles) below the ocean waves.

With the introduction of a single bacterial gene into yeast, researchers have achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol'

In foods, soil samples or customs checks, plant fragments sometimes need to be quickly identified. The use of DNA "barcodes" to itemize plant biodiversity was proposed during the 1992 Rio de Janeiro Summit. Researchers have now tested this method in the tropical forest.

A team of scientists has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth. They focused specifically on the complex process of producing red blood cells (erythrocytes). These cells contain large amounts of hemoglobin, a molecule essential for transporting oxygen throughout the body. The research results could help in the development of important new therapies to combat sickle-cell disease.

When asked to compare apples to apples, consumers said they would pay more for locally grown apples than genetically modified (GMO) apples. But in a second questionnaire consumers preferred GMO apples -- that is, when they were described, not as GMO, but as having a Reduced Environmental Impact. The research demonstrated that product labeling makes a difference when it comes to consumer acceptance.

Amphibians like frogs and toads have existed for 360 million years and survived when the dinosaurs didn't, but a new aquatic fungus is threatening to make many of them extinct, according to a new article.

Two recent studies investigating the use of human umbilical cord blood stem cell (UCB) transplants for lung and heart disorders in animal models found beneficial results. When human UCB-derived mensenchymal cells were transplanted into newborn laboratory rats with induced oxygen-deprived injury, the effects of the injury lessened. A second study found that UCB mononuclear cells transplanted into sheep with a right ventricular malfunction beneficially altered the malfunction and enhanced diastolic function.

The time of day matters to forest trees dealing with drought, according to a new article.

Food production of modern human societies is mostly based on large-scale monoculture crops, but it now appears that advanced insect societies have the same practice. Our societies took just ten thousand years of (mainly cultural) evolution to adopt this habit and we are far from convinced that it is sustainable. Farming ants and termites had tens of millions of years to evolve their fungus farming systems and here monocultures are apparently evolutionary stable.

Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research.

Bird flu viruses would have to make at least two simultaneous genetic mutations before they could be transmitted readily from human to human, according to new research.

A new study suggests that naturally occurring bacteria on the skin of salamanders could help protect other amphibians, including some species of endangered frogs, from a lethal skin disease.

Most countries throughout the world participate in the $40-million-per-year culinary trade of frog legs in some way, with 75 percent of frog legs consumed in France, Belgium and the United States. Scientists have found that this trade is a potential carrier of pathogens deadly to amphibians.

Rodent, reptile and ant lion species behave differently on either side of the Israel-Jordan border. Researchers found that Israeli gerbils are more cautious than their Jordanian friends, and the funnel-digging ant lion population in Israel is unmistakably larger than in Jordan.

A nutritionist in Nigeria says that malnutrition and iron deficiency in schoolchildren could be reduced in her country by baking up snail pie. She explains snail is not only cheaper and more readily available than beef but contains more protein.

Roughly 15,000 years ago, at the end of the last ice age, North America's vast assemblage of large animals -- including such iconic creatures as mammoths, mastodons, camels, horses, ground sloths and giant beavers -- began their precipitous slide to extinction.

New DNA barcoding shows that nearly a third of the tuna plated in sushi restaurants was bluefin -- even if it was not labeled bluefin on the menu.
