A good night's sleep protects against parasites, 3 hours agoAnimal species that sleep for longer do not suffer as much from parasite infestation and have a greater concentration of immune cells in their blood according to a study published in the open-access journal BMC Evolutionary Biology. How many scorpions? London Zoo does critter count, January 08
A meerkat investigates a clipboard during the annual animal count at London Zoo in London, Thursday, Jan. 8, 2009. A complete head count of every animal, insect and bird living at the zoo is to take place, with more than 650 different species to tally up.(AP Photo/Kirsty Wigglesworth)(AP) -- How do you count scorpions? Very gingerly, it turns out. "You use tongs and pick them up by the stinger," London Zoo senior keeper Tony Dobbs said. "You avoid the pincers at all costs. You could get a nasty nick if you're not counting carefully." 'Hobbit' fossils a new species, anthropologist says, January 08An analysis of an 18,000-year-old fossil, described as the remains of a diminutive humanlike creature, proves that genuine cave-dwelling "hobbits" once flourished in Southeast Asia, according to a Long Island anthropologist who conducted X-ray studies of a skull. Trophy heads reveal secrets about ancient South American civilization, January 08The Nasca civilization is perhaps best known for the drawings its people etched onto the desert floor in southwest Peru, a massive and mysterious body of simple and intricate works that span several hundred square miles. Looking through Galileo's eyes, January 08In 1609, exactly four centuries ago, Galileo revolutionised humankind's understanding of our position in the Universe when he used a telescope for the first time to study the heavens, which saw him sketching radical new views of the moon and discovering the satellites orbiting Jupiter. Researchers see exotic force for first time, January 07
This is an artist\'s rendition of how the repulsive Casimir-Lifshitz force between suitable materials in a fluid can be used to quantum mechanically levitate a small object of density greater than the liquid. Figures are not drawn to scale. In the foreground a gold sphere, immersed in Bromobenzene, levitates above a silica plate. Background: when the plate is replaced by one of gold levitation is impossible because the Casimir-Lifshitz force is always attractive between identical materials. Courtesy of the lab of Federico Capasso, Harvard School of Engineering and Applied Sciences(PhysOrg.com) -- For the first time, researchers have measured a long-theorized force that operates at distances so tiny they’re measured in billionths of a meter, which may have important applications in nanotechnology as scientists and engineers seek new ways to create devices far too small for the eye to see. Scientists Propose Thermal Memory to Store Data, January 07Most computers today store memory electronically, by maintaining a certain voltage. In contrast, a new kind of memory that stores data thermally, by maintaining temperature, is being investigated by researchers Lei Wang of the National University of Singapore and the Renmin University of China, and Baowen Li of the National University of Singapore and the NUS Graduate School for Integrative Sciences and Engineering. A miniature synchrotron for your home lab, January 07
The tomographic image of the frog above was reconstructed from 60 transmission projections recorded over 360 degrees. The reconstructed data set has 192 x 192 x 240 voxels, and an isotropic pixel size of 80 microns cubed. A standard filtered back projection algorithm with a Hamming cut off was used. Credit: Prof. Franz Pfeiffer and Lyncean TechnologiesIn 2004 Lyncean Technologies announced the construction of the Compact Light Source (CLS), a miniature synchrotron which uses inverse Compton scattering to produce high-intensity, tunable, near-monochromatic x-ray beams. The CLS was designed to bring state-of-the-art protein structure determination to the home laboratory -- but it has also promised to have a broad impact across the spectrum of x-ray science.

Carbon nanotube 'ink' may lead to thinner, lighter transistors and solar cells, January 08
An atomic force microscope image of semiconducting nanotubes, after the cycloaddition process of removing the metallic tubes. (PhysOrg.com) -- Using a simple chemical process, scientists at Cornell and DuPont have invented a method of preparing carbon nanotubes for suspension in a semiconducting "ink," which can then be printed into such thin, flexible electronics as transistors and photovoltaic materials. Researchers control the assembly of nanobristles into helical clusters, January 08

Courtesy of Aizenberg lab at the Harvard School of Engineering and Applied Sciences(PhysOrg.com) -- From the structure of DNA to nautical rope to distant spiral galaxies, helical forms are as abundant as they are useful in nature and manufacturing alike. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have discovered a way to synthesize and control the formation of nanobristles, akin to tiny hairs, into helical clusters and have further demonstrated the fabrication of such highly ordered clusters, built from similar coiled building blocks, over multiple scales and areas. A Better Way to Make Nanotubes, January 05
The shortest segment of a carbon nanotube has been synthesized for the first time. The compound, called cycloparaphenylene, could usher in a new era of more efficient carbon nanotube production.(PhysOrg.com) -- A compound synthesized for the first time by Berkeley Lab scientists could help to push nanotechnology out of the lab and into faster electronic devices, more powerful sensors, and other advanced technologies. The scientists developed a hoop-shaped chain of benzene molecules that had eluded synthesis, despite numerous efforts, since it was theorized more than 70 years ago. Using light to move and trap DNA molecules, January 02
Microphotos show DNA tagged with a fluorescent dye, flowing through a channel 100 microns (millionths of a meter) wide. Laser light in a slot waveguide laid across the channel traps some of the DNA, which is released when the light is turned off.(PhysOrg.com) -- A major goal of nanotechnology research is to create a "lab on a chip," in which a tiny biological sample would be carried through microscopic channels for processing. This could make possible portable, fast-acting detectors for disease organisms or food-borne pathogens, rapid DNA sequencing and other tests that now take hours or days. sciencenewsdaily.org Privacy Policy
