The team says that until ChEA was developed, no centralized database integrated results from, for instance, ChIP-seq and ChIP-chip experiments (these are used to identify how "transcription factor" proteins might regulate all genes in humans and mice). Now this new computational method should help streamline how scientists analyze these gene expression experiments.
Space Adventures, the company that brokered eight private flights to the International Space Station aboard Russian Soyuz spacecraft, is working with Boeing to launch wealthy space tourists and other non-NASA fliers aboard a capsule under development by the U.S. aerospace giant, officials announced Wednesday.
The Boeing CST-100 capsule, being designed to launch atop Lockheed Martin Atlas 5 rockets, Boeing's Delta 4, or the SpaceX Falcon 9, is intended to carry NASA and European Space Agency astronauts to and from the International Space Station under a NASA initiative to encourage development of private-sector spacecraft.
Fancy a ride to the International Space Station? Boeing will offer space tourism flights in low Earth orbit aboard its Crew Space Transportation-100 (CST-100) spacecraft, expected to be operational by 2015, the company said Wednesday.
Boeing says it has agreed to market the flights through Space Adventures, which has already flown seven private individuals to the International Space Station aboard Russian Soyuz spacecraft.
Extra seats on the CST-100 will be available to private individuals, companies and nongovernmental organizations.
The CST-100 can carry seven people on missions up to 100 kilometers (62 miles) above the Earth's surface. It will deploy … Read more
Four veteran astronauts were named Tuesday to train for a rescue flight aboard the shuttle Atlantis if the crew of NASA's final currently planned mission, scheduled for launch in February, gets stranded in orbit. If not, and if Congress approves funding, NASA hopes to launch the crew for real next June on a final flight to deliver spare parts and supplies to the International Space Station.
But it is not yet clear when differences between the House and Senate versions of NASA's fiscal year 2011 budget will be resolved or when a decision will be made about whether … Read more
Wireless networks and Bluetooth keyboards can free people from some cable clutter, but Fujitsu believes new research could help whisk away some power cords, too.
Fujitsu said Monday that it's overcome design hurdles for a mechanism for wireless charging of electronic devices and that it plans to use the technology in products to be sold in 2012.
The general idea, which Intel, MIT, and other organizations have been researching for years, offers the prospect of a laptop or phone that charges when you set it on a desk or table, potentially getting rid of some cables and making travel easier. Fujitsu has bigger ideas in mind, too: transmitting power within a computer chassis and charging electric cars, for example. … Read more
The dream of having a robot do the dishes may get a step closer with a touch-sensitive electronic skin made of flexible sensors, according to engineers at University of California at Berkeley. And presumably, it wouldn't get dishpan hands.
In a letter published by Nature Materials, the researchers describe a low-power but robust material that would have some of the properties of human skin, such as the ability to feel and touch. Such artificial skin might also help restore limb feeling to amputees.
The e-skin is based on inorganic single crystalline semiconductors. The engineers including Ali Javey and Kuniharu Takei grew germanium/silicon nanowires on a cylinder and then rolled them onto a polyimide film substrate, depositing the wires in a pattern.
The result was a shiny, thin, and flexible electronic material organized into a matrix of transistors, each of which with hundreds of semiconductor nanowires.
A pressure-sensitive rubber was added to the surface of the matrix for sensing. It has the ability to detect pressure from 0 to 15 kilopascals, equivalent to the force needed to grasp light objects. A robot with e-skin hands could handle wine glasses without breaking them.
To show how it can detect pressure, a rubber mold in the shape of the letter C (for "Cal") was placed over the matrix, and about 15 kilopascals of pressure was applied. As seen in the study, the matrix pixels imaged the pressure profile into a blurry but recognizable C.
I'm getting used to the idea of test-driving machines I've never touched, or seen, in person. That's what telepresence robots are all about.
After scooting around in an Anybots' QB robot in July, I recently logged on to a Texai robot (formerly, Texas) over at Willow Garage.
The Silicon Valley firms have been developing wheeled, interactive droids in the belief that people will want to communicate with remote colleagues and friends in a way that some believe is richer than a phone, teleconference, or Web chat. Consumers will likely choose a robot based on design and usability, and the Texai does well on both counts.
The Texai is a Skype- and Web browser-operated remote robot (Willow Garage calls it a "remote presence system") whose main feature is a large color LCD screen showing the pilot. Mostly built from off-the-shelf components, it has two laser range finders, a wide-angle navigation camera, a pan-tilt camera, microphone, and speakers.
Once I was logged on, piloting the Texai through the Willow Garage office was pretty much a snap. With the Skype video call window showing the front and low-angle camera views, I moved around by clicking on and dragging a red ball in a Texai navigation window in my browser. I liked the fact that everyone could clearly see who I am on the screen, and I could easily see the faces of other Texai pilots through my Skype window.
The Texai lacks some features of the Anybots QB robot, such as the laser pointer, doorway navigation assist, and remote room lighting controls. But it's very intuitive to navigate once you get used to the setup--I poked my LCD head into a Willow Garage meeting, rolled into the company lounge and ran into another Texai user in the hallway, like robots passing in the night. … Read more
Schwartz wasn't very forthcoming about the nature of the start-up, saying on his personal blog Thursday little specifically besides that "We're focusing on the intersection of innovation and public health."
As of this week, they're finally available to the general public. The helper robots we've been seeing in sci-fi movies for years are here to fold your laundry, wash your dog, care for your elderly relatives, and lie to your spouse--if you have $400,000, that is.
The open-source PR2 robot from Willow Garage stands about 5 feet tall, has two articulated arms and stereo vision, and is apparently very smart. The bots can be programmed to undertake tons of jobs using more than 1,000 software libraries, if you're up to the task.
KENNEDY SPACE CENTER, Fla.--Running a day late because of a ruptured water main, the shuttle Discovery was hauled from its processing hangar to the Vehicle Assembly Building Thursday for attachment to an external tank and twin solid-fuel boosters. If all goes well, the orbiter will be moved to launch pad 39A on September 21, setting the stage for launch November 1 on a space station resupply mission.
It will be the shuttle program's 133rd flight and the 39th and final voyage of Discovery before NASA's oldest shuttle is retired and put on public display, most likely at … Read more
