Resilient Space Internet Comes Down to Earth Gadgets with Android

A new Internet protocol designed for interplanetary transmissions is bringing its delay-tolerant magic to Earth

Google's Android does a lot more these days than just smart phones and nifty mobile gadgets. An Internet pioneer is using the platform to launch a interplanetary Internet protocol on Earth that could harden wireless networks against delays in data transmission.

How Much Power Does The Human Brain Require To Operate?

Simulating the brain with traditional chips would require impractical megawatts of power. One scientist has an alternative

According to Kwabena Boahen, a computer scientist at Stanford University, a robot with a processor as smart as the human brain would require at least 10 megawatts to operate. That's the amount of energy produced by a small hydroelectric plant. But a small group of computer scientists may have hit on a new neural supercomputer that could someday emulate the human brain's low energy requirements of just 20 watts--barely enough to run a dim light bulb.

Armored Airbags to Protect Vehicles from RPGs and Roadside Bombs

Airbags could prevent RPGs from exploding and neutralize the blast of improvised explosives

Despite the vehicles' armor, rocket-propelled grenades (RPGs) can still take out Humvees and MRAP vehicles with ease. But a company wants to change that equation with airbags that neutralize incoming RPGs and prevent them from exploding.

Nanoparticles Can Damage DNA Without Crossing Cellular Barrier

Metal nanoparticles use a newly observed cell signal process to wreak havoc indirectly

Scientists know that nanoparticles can damage DNA in cells through direct interaction. Now, though, it appears that nanoparticles can also mess with DNA on the far side of a cellular barrier, by creating signaling molecules -- a never-before-seen phenomenon.

Video: Microsoft Demonstrates Next-Gen Interface, with Motion Sensing and Eye Tracking

A transparent glass display adds touchless gestures and eye-tracking to human-computer interaction

Pen and voice input for computers is so early-millennium. Now Microsoft has created a next-gen computer concept that includes touchless gestures and eye-tracking, and has taken the device on a college tour with chief research and strategy officer Craig Mundie.

Space Hotel Reportedly On Track for 2012 Opening, Already Has Paying Guests

A company aiming to open the first space hotel already has 43 paying customers at $4.4 million a pop

Anyone with a cool $4 million and change might consider doing what 43 other people have done, and sign up for an orbital space vacation in 2012 with Galactic Suite Space Resort. The Barcelona-based company plans to open the first space hotel if all goes according to plan.

Remembering a Former Caltech Rocket Scientist and the Founder of China's Space Program

Qian Xuesen has died at 98; he helped found Caltech's Jet Propulsion Laboratory before being deported as a suspected Communist

One can only imagine how history might have played out if the United States had not deported a Chinese-born Caltech rocket scientist on suspicion of being a Communist in 1955. Qian Xuesen first fought his deportation, but later accepted his fate and went on to become the founder of China's missile and space programs. His death this past Sunday comes as China broadens its space exploration efforts to become a potential challenger to a troubled U.S. space program, or perhaps a partner.

New Genomic Zoo to Collect DNA of 10,000 Vertebrate Species

The massive Genome 10K Project will help biologists watch evolution in action on the genetic level

A new "genomic zoo" has launched, with the goal of sequencing the genomes of 10,000 vertebrate species. The project aims to help researchers understand recent and rapid adaptive changes among the species. It could also allow predictions of how certain species might respond to climate change, pollution, new diseases and competitors.

The Genome 10K Project will scour zoos, museums and universities worldwide for thousands of specimens. An international coalition of more than 68 scientists has outlined their plans in a paper that will appear tomorrow in the Journal of Heredity.

As Space Collision Threat Looms, Pentagon Upgrades Its Monitoring of Satellites

The U.S. Air Force has upgraded its ability to predict possible satellite collisions, as the risk from space debris increases

Satellites currently must dodge an ever-growing gauntlet of other satellites and clouds of space debris, and this year the Pentagon has quietly upgraded its surveillance accordingly. The U.S. military announced yesterday that it now tracks 800 maneuverable satellites, compared to less than 100 prior to a February collision between an active U.S. satellite and a retired Russian communications satellite.

Object-Detection Software to Enable Search Within Videos

Detection algorithms help computers find humans, or anything else, in YouTube videos or surveillance footage

Imagine running a Google search for basketball videos, and having your computer sift through actual footage of online videos rather than just the text of the descriptions. A new type of software could enable computers to run searches inside videos, and pick out humans and objects alike.
