Microsoft, Google, Hewlett-Packard, and a host of other companies are providing funds and resources to the Startup America Partnership to further the group's goal of fostering the entrepreneurial spirit.
More than 15 companies will kick in a total of $400 million in money, services, training, and other benefits that will go directly to entrepreneurs trying to get their ideas and businesses off the ground.
Two professors at Binghamton University in New York are using a novel imaging technique to observe the behavior of an enzyme--called tubulin tyrosine ligase, or TTL--as its behavior can suggest whether certain cancer cells might grow more aggressively than others.
"Potentially, we could put [a tumor sample] in our labeling system and say, 'Yes, that has a problem with the TTL system, and therefore you should be more aggressive with it,'" says Gal, whose work is funded by the National Institute of General Medical Sciences. "Or we could say, 'That's probably OK, so you can treat it with normal chemotherapy.'"
The enzyme TTL involves microtubules, which both help chromosomes line up correctly during cell division and provide part of the scaffolding of a cell's structure. Those microtubules are made of proteins called tubulin; the enzyme carboxypeptidase clips an amino acid called tyrosine off the ends of some of these proteins, and later the enzyme TTL puts that tyrosine back on.
Bane says it's unclear why tyrosine is clipped off only to be reattached, but it's clearly an important part of the cell's cycle: "We do know that if you don't have that enzyme, you'll die."
In some cancer cells, that cycle of removing and reattaching tyrosine is disrupted, with too many tubulins lacking tyrosine altogether. Tumors made of those cells, Bane says, "tend to grow more aggressively."… Read more
Two companies tied to prominent technology entrepreneurs are among those that received funding through the NASA's Commercial Crew Development effort, the government agency announced yesterday.
Blue Origin, which was started by Amazon founder Jeff Bezos, received $22 million in the funding round. PayPal co-founder Elon Musk's SpaceX received $75 million. They were flanked by Sierra Nevada and Boeing, which received $80 million and $92.3 million, respectively.
The Commercial Crew Development program, which began in 2009, is arguably one of the most important efforts under way at NASA. Its goal is to help U.S. private enterprises develop … Read more
One of the annoying things about getting older--and yes, there are more than a few--is how frequently you discover that what you were taught either is now outdated or simply flat wrong. But don't get too down about it. Scientists only now are realizing that they've misunderstood the physics of what keeps bicycles upright.
For as long as anyone can remember, the science behind why a bike remains stable once it reaches a certain speed had to do with wheel rotation and the stability generated by so-called gyroscopic effects. Also, there was the proper distance between the steering … Read more
Any time someone concatenates the words "Paul Allen," "brain," and "science" in one sentence, two assumptions can safely be made: What's being described will be expensive; what's being described will be newsworthy.
And so it comes as little surprise that the Seattle-based Allen Institute for Brain Science announced this week a world first: a highly detailed guide to both the anatomy and the genes of the human brain that includes 1,000 anatomical landmarks backed by 100 million data points measuring the strength of gene activity at each landmark. The cost of … Read more
Mobile gadgets like Apple's iPad and iPhone could offer glasses-free 3D courtesy of a new, developing technology created by researchers in France.
Known as Head-Coupled Perspective, the technology uses the front-facing camera on a mobile device to create a glasses-free monocular 3D display. By tracking the position of the user's head, the projected 3D image can change its perspective and offer greater interaction. Even further, the technology doesn't rely on the accelerometer built into the iPhone and iPad, so it could conceivably work for other types of mobile devices.
The researchers behind this budding technology are Professor … Read more
If you're a commuter stuck in traffic, it doesn't help you all that much to know what road conditions are like right now. You already know you're being delayed. But what if there was a way to alert you to problems before you even get in your car?
That's the premise behind a new project being announced tonight by IBM Research, the California Department of Transportation (Caltrans), and the University of California at Berkeley's California Center for Innovative Transportation (CCIT).
The idea behind the project is simple: as a commuter, you're better off if … Read more
CAMBRIDGE, Mass.--Tim Berners-Lee, who invented the underpinnings of the World Wide Web, isn't just concerned about getting browsers on more mobile devices. Architects of the Web need to consider how it will affect all humanity as it evolves.
KENNEDY SPACE CENTER, Fla.--Ending months of suspense, NASA Administrator Charles Bolden today announced the winners of a national competition to display the agency's three space shuttles after the fleet is retired and decommissioned later this year, choosing sites in Florida, California, and, as expected, the Washington, D.C., area.
Speaking on the 30th anniversary of the first shuttle flight on April 12, 1981, Bolden said the shuttle Discovery, NASA's senior orbiter, will be displayed near Washington at the Smithsonian National Air and Space Museum's Steven F. Udvar-Hazy Center.
The shuttle Atlantis will remain at the Kennedy … Read more
The crew of the International Space Station joined Russian leaders and space officials, their NASA counterparts, and international partners around the world to celebrate the 50th anniversary of Yuri Gagarin's launch on April 12, 1961, to become the first human in space.
"In the 20th century, it has become the most extraordinary event, the most significant event not only in Russia but the whole world and we're very proud of the fact that the first cosmonaut went into space on April 12, 1961, and he was our compatriot," Anatoly Perminov, director general of the Russian space … Read more
