Vascular composites enable dynamic structural materials
Vascular composites enable dynamic structural materials
CHAMPAIGN, Ill. Taking their cue from biological circulatory systems, University of Illinois researchers have developed vascularized structural composites, creating materials that are lightweight and strong with potential for self-healing, self-cooling, metamaterials and more. "We can make a material now that's truly multifunctional by simply circulating fluids that do different things within the same material system," said Scott White, the Willet Professor of aerospace engineering who led the group.

Researchers Create the First Artificial Neural Network Out of DNA
PASADENA, Calif.—Artificial intelligence has been the inspiration for countless books and movies, as well as the aspiration of countless scientists and engineers. Researchers at the California Institute of Technology (Caltech) have now taken a major step toward creating artificial intelligence—not in a robot or a silicon chip, but in a test tube.

Honey bee tolerates some synthetic pesticides
Honey bee tolerates some synthetic pesticides
CHAMPAIGN, lll. A new study reveals how enzymes in the honey bee gut detoxify pesticides commonly used to kill mites in the honey bee hive. This is the first study to tease out the precise molecular mechanisms that allow a pollinating insect to tolerate exposure to these potentially deadly compounds.

New light on otter mystery
New light on otter mystery
The solitary and mysterious lives of British otters are being uncovered by Cardiff scientists - thanks to help from the public. Otters were already understood to use scent as their main means of communication. However, little was known about what information was communicated or the social functions of the scent.

Diesel particles pose heart risks
Tiny chemical particles emitted by diesel exhaust fumes could raise the risk of heart attacks, research has shown. University scientists have found that ultrafine particles produced when diesel burns are harmful to blood vessels. They can increase the chances of blood clots forming in arteries, leading to a heart attack or stroke.

Research update: New way to store sun’s heat
Modified carbon nanotubes can store solar energy indefinitely, then be recharged by exposure to the sun. CAMBRIDGE, Mass. A novel application of carbon nanotubes, developed by MIT researchers, shows promise as an innovative approach to storing solar energy for use whenever it's needed. Storing the sun's heat in chemical form ' rather than converting it to electricity or storing the heat itself in a heavily insulated container ' has significant advantages, since in principle the chemical material can be stored for long periods of time without losing any of its stored energy.

Large human study links phthalates, BPA and thyroid hormone levels
Listen to podcast ANN ARBOR, Mich.—A link between chemicals called phthalates and thyroid hormone levels was confirmed by the University of Michigan in the first large-scale and nationally representative study of phthalates and BPA in relation to thyroid function in humans. The U-M School of Public Health study also reported suggestive findings consistent with a previously reported link between a chemical called bisphenol-A and thyroid hormone levels.

DNA cages 'can survive inside living cells'
DNA cages 'can survive inside living cells'
Scientists at Oxford University have shown for the first time that molecular cages made from DNA can enter and survive inside living cells. The work, a collaboration between physicists and molecular neuroscientists at Oxford, shows that artificial DNA cages that could be used to carry cargoes of drugs can enter living cells, potentially leading to new methods of drug delivery.

Pigment patterns from the prehistoric past
Pigment patterns from the prehistoric past
An international collaboration led by researchers at The University of Manchester has for the first time revealed chemical traces of pigments in bird, fish and squid fossils, some over 100 million years old. Publishing their findings in Science , the researchers have been able to show a remarkable relationship between copper and pigment within exceptionally preserved feathers and other soft tissues.

Discovery of the most distant quasar lets astronomers observe the nascent universe
Discovery of the most distant quasar lets astronomers observe the nascent universe
by Simon Levey Thursday 30 June 2011 An international team of astronomers has announced the discovery of the most distant quasar yet seen. The quasar is an extremely bright source of light visible at infrared wavelengths, emitted as gas falls into a very massive black hole. The scientists have named it ULAS J1120+0641.

Preventing diabetes damage: Zinc’s effects on a kinky, two-faced cohort
ANN ARBOR, Mich.—In type 2 diabetes, a protein called amylin forms dense clumps that shut down insulin-producing cells, wreaking havoc on the control of blood sugar. But zinc has a knack for preventing amylin from misbehaving. Recent research at the University of Michigan offers new details about how zinc performs this "security guard" function.

Archaeological dig uncovers artefacts
Scientific equipment belonging to an Enlightenment figure has been found in an archaeological dig at the University. The eighteenth-century items, including laboratory apparatus and brightly coloured chemicals, almost certainly were the property of Joseph Black. Black was Professor of Chemistry at Edinburgh and is best known for his discovery of carbon dioxide gas.

Researchers solve problem filling space -- without cubes
Researchers solve problem filling space -- without cubes
by Gale Scott Whether packing oranges into a crate, fitting molecules into a human cell or getting data onto a compact disc, wasted space is usually not a good thing. Now, in findings published June 20 in the Proceedings of the National Academy Sciences, Princeton University chemist Salvatore Torquato and colleagues have solved a conundrum that has baffled mathematical minds since ancient times - how to fill three-dimensional space with multi-sided objects other than cubes without having any gaps.

New discoveries in diabetes
New discoveries in diabetes
[NEWS 21 June 2011] A new signal pathway that renders the insulin-releasing beta cell more sensitive to high levels of blood glucose has been discovered by researchers at Karolinska Institutet. A second new study reveals a possible way to delay the disease by inhibiting a lipoprotein. A new joint study published and conducted by researchers at Karolinska Institutet's Department of Molecular Medicine and Surgery and their American colleagues provides new insights into how beta cells react to raised concentrations of blood sugar, which occur, for example, after a meal.

Do steaks make you big?
Do steaks make you big?
Adjusting the intake of high protein foods like meat, eggs and milk products could determine whether you become a rugby player or marathon runner and may help you lose weight, according to new research published this month in the Journal of Biological Chemistry . Dr Stefan Broer, head of the molecular nutrition group in the ANU College of Medicine, Biology and Environment at The Australian National University, said the study by a group of ANU and Sydney researchers could potentially lead to the development of new weight-loss drugs.
