Opinion - Three researchers working in collaboration have developed a truck/SUV spoiler that is unlike other spoilers. The team adapted fluid dynamics algorithms to produce an unexpected design which they claim yields a 5% reduction in drag and a complete reversal of lift. While stating the average SUV user could save $100 or more in annual fuel costs, the designers are being rather tight-lipped about this new design.
The path toward reliably and effectively creating sheets of graphene has just gotten one step closer. Researchers at UCLA used a bath of hydrazine (nitrogen + hydrogen) and graphite oxide paper to create the sheets which are just one atom thick. In addition, and perhaps most exciting, the electrical properties of graphene created in this way allow field-effect devices (semiconductors) with drive currents 1000x higher than has been previously reported. In short, the elusive dream of graphene-based technologies applied to semiconductors, optics, solar cells, batteries, and pretty much everything else, is closer now than ever before.
Researchers at Germany's Fraunhofer-Gesellschaft have developed a liquid crystal lubricant that reduces friction to almost zero. Built of the same materials inside our LCD monitors, for applications like gears and bearings this new discovery may put oil out of business.
NASA officials said Monday that the organization’s Phoenix Mars Lander
has ceased communications after operating for more than five months or
152 Martian days. The end may have come sooner than expected as there
is not enough sunlight for the solar arrays to charge the lander’s
batteries and provide power for its instruments. The mission concluded
with a dramatic series of discoveries, such as clear evidence of water
on Mars as well as Martian snow.
Zhong Lin Wang and a team of researchers from Georgia Institute of Technology (GIT) have developed a super-tiny zinc-oxide alternator that generates power through vibrations. Wang believes that someday an energy source of this kind may provide power for nano-devices operating inside the human body - those powered by internal vibrations coming from blood flow. Such a device may also be worn as clothing, generating power through regular daily activity.
In a paper so potentially significant that only two-thirds of the physicists involved were willing to sign their name to it at this early stage, evidence is beginning to leak out that researchers at Fermilab may have discovered a new particle. While yet unnamed, the scientists are being extremely cautious moving forward. They've released a paper at this unusually early stage to help tame speculation and conjecture. It's being reported that no "Standard Model" accounts for the observations witnessed in 23% of collisions, a value too far outside the range statistical fluctuation to be mere coincidence.
Honda today unveiled what some may consider, at least at first sight,
as the ultimate anti-workout tool – a walking assist device with a
dedicated bodyweight support system. Walking up stairs too exhausting?
No problem, this device can help. And no, it is not a product that aims
to support handicapped people. But Honda claims that there are
occasions in which we all can benefit from a device that puts extra
muscles around your legs.
Dr. Wu-chun Feng of Virginia Tech University created the Green500 list, a metric of performance per watt of the top 500 supercomputers in the world. By calling attention to power consumption issues, his ranking serves as a type of gage allowing outsiders to view computing power in relative terms. A company called SiCortex believes that much more is needed in this area and proposes a new Green Computing Performance Index (GCPI) that changes the way performance-per-watt is measured across an entire server farm.
About a year ago, The Pirate Bay, one of the most popular BitTorrent
tracking services in the world, reported about 8 million users. On
Thursday, the service reported that it now has a global user base of 22
million users who share software, movies, music, games and pretty much
anything else that can be distributed as digital files.
Gary A. Strobel, professor of plant pathology at Montana State University, has recently published his findings on a type of microscopic fungus living in trees, called Gliocladium roseum, which naturally gives off components of rocket fuel and diesel fuel. Strobel believes organisms like these which shed raw hydrocarbon components could be partially responsible for the vast underground oceans of crude oil we have today. In addition, he also sees them as a path toward new ways of producing bio-fuels. Could the fungus among us be the key in a tree which powers our needs to eternity?
Scientists at the University of South Florida have created some of the smallest usable solar cells ever constructed. So small that 20 of them could line up one inch. Each array generates about 7.8 volts at very low amperage. They provide power for nano-sized chemical sensors (made from carbon nanotubes) to detect chemical leaks at remote locations inside factories and transports. These researchers are proving that smaller can be better.
Feature - More numbers about the 2008 presidential campaign are
surfacing: Join us for a look at the web audience, fundraising, cost
and young voter turnout surrounding a billion dollar election.
This year’s presidential election made history in several ways and it
appeared that news networks were also in a competition to show off the
most elaborate technology to explain polls and other election events.
It all started with fancy Surface tables and a “Magic Wall”, but if
there was one technology that completely stood out form everything
else, it was certainly CNN’s holograms.
