Glowing fish shed light on metabolism
A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders.

Cell surface transporters exploited for cancer drug delivery
According to Whitehead Institute researchers, a protein known as monocarboxylate transporter 1 (MCT1), which is highly expressed in a subset of metabolically altered cancer cells, is needed for the entry of the investigational cancer drug 3-bromopyruvate (3-BrPA) into malignant cells. This work may open a new avenue for cancer therapeutic research, as other transport molecules have already been identified on the surface of certain cancer cells.

A shock to pollution in chemistry
Solvents are everywhere in chemistry and a major environmental concern. High-frequency milling is an energy-efficient alternative: the impact of steel balls in a rapidly moving jar drives reactions. Direct observation of the underlying chemistry is difficult but scientists used X-rays to observe, for the first time, in real time the chemistry when a mill mixes, grinds and transforms simple ingredients into a complex product. The study opens new opportunities in Green Chemistry and environmentally-friendly synthesis.

Origin of intelligence and mental illness linked to ancient genetic accident
Scientists have discovered for the first time how humans -- and other mammals -- have evolved to have intelligence. Researchers have identified the moment in history when the genes that enabled us to think and reason evolved.

Scientists at Scripps Research Institute discover how 2 proteins help keep cells healthy
Scientists at The Scripps Research Institute have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health. This discovery opens the door for research on substances that could interfere with the formation of these organelles and lead to new therapies for cancer.

Genes linked to low birth weight, adult shortness and later diabetes risk
An international team of genetics researchers has discovered four new gene regions that contribute to low birth weight. Three of those regions influence adult metabolism, and appear to affect longer-term outcomes such as adult height, risk of type 2 diabetes and adult blood pressure. The cumulative effect of the genes is equivalent to the effect of maternal smoking during pregnancy.

New gene-sequencing tools offer clues to highest-risk form of a childhood cancer
Using powerful gene-analysis tools, researchers have discovered mutations in two related genes, ARID1A and ARID1B, that are involved in the most aggressive form of the childhood cancer neuroblastoma. While these findings do not immediately improve clinical treatments, they identify a novel pathway that is defective in these cancers, a pathway that scientists can now study to develop potential new therapies.

The role of the cellular entry point of anthrax identified
Anthrax uses a receptor on the surface of cells to inject its lethal toxins. However, the physiological function of this receptor, named Anthrax Toxin Receptor 2a (Antxr2a), remained unknown until now. A team led by Marcos Gonzalez-Gaitan, a professor at the University of Geneva, Switzerland, in collaboration with Gisou van der Goot at EPFL, reveals that Antxr2a actually plays a role in embryonic development, orienting cell division along a specific plane.

Insights into the genetic causes of coronary artery disease and heart attacks
By identifying a further 15 genetic regions and 104 independent genetic variants associated with coronary artery disease, one of the most common causes of death in the worldwith, researchers have identified some of the most prominent biological pathways that underlie the disease. These pathways that control CAD could be targets for the development of new drug treatments in the future.

X-ray analysis deciphers master regulator important for skin cancer
With the X-ray vision of DESY's light source DORIS, a research team from Hamburg and Iceland has uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma. The results, published in the scientific journal "Genes & Development", throw new light on the workings of the so-called Microphthalmia-associated Transcription Factor MITF, that is not only connected to skin cancer, but also to a variety of hereditary diseases.

Long-term research reveals how climate change is playing out in real ecosystems
Around the world, the effects of global climate change are increasingly evident and difficult to ignore. However, evaluations of the local effects of climate change are often confounded by natural and human induced factors that overshadow the effects of changes in climate on ecosystems. Now, a group of scientists writing in the journal BioScience report a number of surprising results that may shed more light on the complex nature of climate change.

Researchers identify a mechanism for the transformation of colon polyps
The causes underlying the development of certain types of common cancers have not yet been elucidated. In order to better determine the origin and the sequence of events responsible for the onset of colon cancer, the teams led by Thanos Halazonetis and Stylianos Antonarakis, professors at the UNIGE, Switzerland, have sequenced the DNA of biopsied tissue from colon polyps. The results show that these precancerous lesions have a specific profile.

Native Americans and Northern Europeans more closely related than previously thought
Using genetic analysis, scientists have discovered that Northern European populations descend from a mixture of two very different ancestral populations, and one of these populations is related to Native Americans. This discovery helps fill gaps in scientific understanding of both Native American and Northern European ancestry, while providing an explanation for some genetic similarities among what would otherwise seem to be very divergent groups.

Making sustainability policies sustainable
Sweeping environmental policies come with hidden challenges -- not only striving to achieve sustainability and benefit the environment -- but over time ensuring the program itself can endure. Scientists at Michigan State University and their colleagues in China are examining China's massive Grain to Green Program -- an effort to persuade farmers to return cropland to forest through financial incentives. Their results were reported in this week's journal Ecological Indicators.
