Bio-inspired Fibres Change Colour When Stretched

A team of materials scientists at Harvard University and the University of Exeter has invented a new fibre which changes colour when stretched. Inspired by nature, the researchers identified and replicated the unique structural elements, which create the bright iridescent blue colour of a tropical plant’s fruit.

The multilayered fibre, described in the journal Advanced Materials, could lend itself to the creation of smart fabrics that visibly react to heat or pressure.

“Our new fibre is based on a structure we found in nature, and through clever engineering we’ve taken its capabilities a step further,” says lead author Dr Mathias Kolle, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS). “The plant, of course, cannot change colour. By combining its structure with an elastic material, however, we’ve created an artificial version that passes through a full rainbow of colours as it’s stretched.” (more…)

Genome-wide Atlas of Gene Enhancers in the Brain On-line

Collaboration Led by Berkeley Lab Researchers Creates High-Resolution Map of Gene Regulatory Elements in the Brain

Future research into the underlying causes of neurological disorders such as autism, epilepsy and schizophrenia, should greatly benefit from a first-of-its-kind atlas of gene-enhancers in the cerebrum (telencephalon). This new atlas, developed by a team led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) is a publicly accessible Web-based collection of data that identifies and locates thousands of gene-regulating elements in a region of the brain that is of critical importance for cognition, motor functions and emotion.

“Understanding how the brain develops and functions, and how it malfunctions in neurological disorders, remains one of the most daunting challenges in contemporary science,” says Axel Visel, a geneticist with Berkeley Lab’s Genomics Division. “We’ve created a genome-wide digital atlas of gene enhancers in the human brain – the switches that tell genes when and where they need to be switched on or off. This enhancer atlas will enable other scientists to study in more detail how individual genes are regulated during development of the brain, and how genetic mutations may impact human neurological disorders.” (more…)

Even Adaptable Viruses Have Trouble Surviving Erratic Temperatures

Viruses such as those that cause the common cold are some of the most hardy and adaptable things on earth, but even they have trouble surviving the unpredictable and sudden temperature changes predicted by climate change models. (more…)

New Book Traces Black Panthers’ Evolution from Local Activists to Global Anti-Imperialists

History has long denied the political genius of the Black Panther Party. At worst, its members have been cast as unconscionable criminals. At best, such seminal figures as party founders Huey Newton and Bobby Seale and early supporter Stokely Carmichael have been portrayed as outlaw folk heroes who, propelled by the progressive winds of the late 1960s, dared to take on the establishment.

But a UCLA graduate student in sociology who worked alongside former Panthers a decade ago as a community organizer in Oakland, Calif., didn’t buy the conventional wisdom. (more…)

IBM Forges New Routes to Market with Power and Storage Systems Tuned for Big Data and Cloud Computing

Johannesburg, South Africa – 05 Feb 2013: IBM today accelerated its strategy to make big data and cloud computing a reality for businesses of all sizes with new Power Systems and Storage Systems that provide deep insights into big data, simplify data storage in the cloud, and can reduce costs through consolidation.

Mutant Gene Responsible for Pigeons’ Head Crests

Decoded genome reveals secrets of pigeon traits and origins

Scientists have decoded the genetic blueprint of the rock pigeon, unlocking secrets about pigeons’ Middle East origins, feral pigeons’ kinship with escaped racing birds and how mutations give pigeons traits like feather head crests.

“Birds are a huge part of life on Earth, but we know surprisingly little about their genetics,” says Michael Shapiro, one of the study’s two principal authors and a biologist at the University of Utah. (more…)

How Planets Form: Astronomers Weigh a Protoplanetary Disk with Unprecedented Accuracy

ANN ARBOR — In a study that gives astronomers new insights into how planets form, research led by the University of Michigan has enabled a dramatically more precise measurement of the amount of dust and gas in the planet-forming disk around a young star.

The findings speak, in a way, to a fundamental question: “Why are we here?” (more…)
