... engineered structures appear to have regenerative powers that could potentially lead to therapies for conditions such as Alzheimers, nerve injury and brain damage from stroke. Dr. Andrew Maynard, chief science advisor for the Wilson Centers Project on Emerging Nanotechnologies, and Dr. Mauro Ferrari, cha...

Research without borders: Head of Santa Fe Institute to address NSF

...increase with exponents which are typically simple powers of 1/4. It will be shown how these scaling laws follow from fundamental generic principles embedded in the dynamical and geometrical structure of underlying networks, leading to a general quantitative theory that captures essential features of many...

Researcher finds negative effects of colonization on slash-and-burn farming method in western Borneo

...d growth forests. During this period, the colonial powers sought to pacify the Iban and stop their traditional practice of headhunting. Punitive expeditions involved burning Iban longhouses, slashing rice fields and felling fruit trees. In the process, Wadley argues, the Iban became unsettled and demoralize...

Research project tackles 'regeneration' gap

...ets of regeneration from creatures with remarkable powers of self-renewal, such as salamanders, newts, starfish and flatworms. Fueled by about $6 million in private donations, university support and state matching funds, "The Regeneration Project" will connect scientists who work with adult human stem cel...

Researchers figure out what makes a simple biological clock tick

...th adenosine triphosphate (ATP), the chemical that powers biological reactions. "That was a big surprise," says Carl Johnson, the professor of biological sciences who headed the new study. "We all thought the system was much more complicated and required feedback from the cells genetic machinery in order to...

Cholera pathogen reveals how bacteria generate energy to live

...and inside. This gradient acts like a battery that powers essential cell functions, such as the movement of the bacteriums tail, the flagellum. Most cells, including human cells, use gradients of protons for this energy conservation function, but enzymes that work with sodium ions are ideal for experiment...

How does a zebrafish grow a new tail?

... creatures, might still have untapped regenerative powers hidden in their genes. People are constantly renewing blood components, skeletal muscles and skin. We can regenerate liver tissue and repair minor injuries to bone, muscle, the tips of our toes and fingers, and the corneas of our eyes. Finding out m...

Breakthrough for future exploration unrecoverable gas reserves

... is made up of many thin channels, the centrifugal powers press the droplets to the outer side of the channels. The CO2 and H2S can then be relatively easily separated from the natural gas. Prototype The prototype Van Wissen built can process a gas stream of 60 m3 an hour. Very little, compared to the m...

The pull of bacterial chromosome segregation

...1st issue of G&D reveals that a mitotic-like motor powers chromosome segregation in prokaryotes. Studying the bacteria Vibrio cholerae, Drs. Michael Fogel and Matthew Waldor (Tufts University School of Medicine) determined that the chromosome-encoded Par proteins generate a pulling force similar to that fo...

Microorganisms one part of the solution to energy problem, says report

...electricity that warms your home, cooks your food, powers your television and washes your clothes. All these futuristic energy technologies may become reality some day, thanks to the work of the smallest living creatures on earth: microorganisms," Wall says. The world faces a potentially crippling energy ...

Dartmouth researchers identify a gene that enhances muscle performance

...at the carbohydrate, glucose, is a major fuel that powers muscles, and this contributes directly to a muscle's ability to repetitively contract during exercise. The activated AMPK in the Dartmouth mouse appears to have increased glycogen content by actually switching on a gene that normally synthesizes live...

Ants were trained to search for food between two cylinders of different sizes and then tested with the training cylinders replaced by two cylinders of the same size. Would ants know which cylinder is which...

Of I robots go solar; new system could drastically reduce herbicide use

...They have also mounted the curved solar panel that powers the robot. "We custom-built a shelf that holds the solar panel," said Gingrich. "It also protects the machine from weather and gives it shade for its vision system." Although the robot is equipped with ultrasonic sensors that go all the way aroun...

Researchers image molecular motor structural changes

...rt materials within cells generate the energy that powers their movements. The knowledge could lead to better understanding of the underlying mechanisms of a range of human disorders such as Down syndrome caused by faulty molecular motors, and possibly to the development of new treatments, the researchers ...

Animal physiology conference sheds light on human physiology

...of the bags: The Red Knot's pectoral muscle, which powers its wings, increases by 30-50% of its normal size in the weeks leading up to migration. Its heart grows bigger, fat stores balloon and digestive tracts shrink precipitously. The bird's blood thickens, making it possible to deliver more oxygen to the ...

Super-high resolution optical microscopes, with powers that seemed physically impossible a decade ago, are poised to open a new era in imaging in molecular biology, according to a report scheduled for the Sept. 4 issue of Chemical & Engineering News, the ACS' weekly news magazine. The new optical micro...
