A new, finely tuned light-based treatment kills cancer cells in mice without harming the tissue around them, and could conceivably used to treat a wide range of human cancers, researchers say. The therapy is much more precise than other light-therapy methods attempted to date, and it has the potential to replace chemotherapy and radiation.
BAE Systems's Adaptiv technology enables objects as big as tanks to completely vanish from view--when seen at night with an infrared sensor, admittedly, but that's still a major advantage. An Adaptiv-outfitted tank can change its thermal signature to look like anything from a big rock to a truck to nothing at all, fading into the background and becoming invisible.
The PIN digits you punch into an ATM’s keypad to authenticate your transactions are leaving traces of themselves behind in the form of heat, says a paper recently presented by a team of UC San Diego security researchers. Someone following immediately behind an ATM user can use a digital infrared camera to determine what keys were pushed with about 80 percent accuracy, their study shows. Even a full minute later the camera can pick up the correct digits about half the time.
Using NASA’s Wide-field Infrared Survey Explorer telescope, astronomers have finally spotted a collection of ultra-cool brown dwarfs they have been hunting for more than a decade. These tepid almost-star orbs are nearly impossible to see with a normal telescope, but WISE’s infrared vision was able to pick them out.
The center of the Milky Way is hard to see in visible light, because interstellar dust blocks our view. But the Spitzer Space Telescope’s infrared vision can penetrate the dust and see through to our galaxy’s jam-packed core.
This is a newly updated version of the plane of the Milky Way captured by the Spitzer telescope. NASA says the area shown here is immense: Horizontally, it spans 2,400 light years, or 5.3 degrees of the sky, and vertically it covers 1,360 light years, or 3 degrees.
For a team of technology whiz kids at the University of Groningen in the Netherlands, having a 3-D theater to work in just wasn’t enough. Using the curved 33-by-9-foot 3-D screen, a group there has created a touchscreen capable of more than 100 points of simultaneous contact.
After months of calibration and testing, NASA’s flying telescope made its first excursion this morning, and the space agency is looking forward to analyzing the results. But, um, isn’t this sort of blurry?
Huge cost overruns caused by mismanagement of the James Webb Space Telescope are delaying NASA’s keystone science project yet again, and could wreak havoc on the agency’s remaining astrophysics budget, a congressional panel found this week.
German researchers at the Fraunhofer Institute for Digital Media Technology have developed an eyetracking device that could soon help keep drowsy drivers alert on the road for a fraction of the cost of existing systems.
After almost a year of successfully surveying the entire sky one-and-a-half times over, NASA's Wide-Field Infrared Survey Explorer has run out of coolant – quite expectedly – and reached the end of its primary mission. Since its launch last December, the mission snapped more than 1.8 million images in four different infrared wavelengths, providing astronomers with enough data to keep them busy combing through it for decades. That is to say, WISE has had a very productive year.
