How to thermally cloak an object
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter......»»
Optimal information about the invisible
Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required—and this prerequisite is not always satisfied. In biomedicine, for example, structures are exami.....»»
New research demonstrates how the best camouflage can be found for an arbitrary environment
A new method, developed by scientists at the University of Bristol can determine the optimal colouration pattern to cover an object in order to make it as visible or concealed as possible, in any given environment......»»
A mathematical framework enables accurate characterization of shapes
In nature, many things have evolved that differ in size, color and, above all, in shape. While the color or size of an object can be easily described, the description of a shape is more complicated. In a study now published in Nature Communications,.....»»
Penn State Engineers Are Developing An Inexpensive, Thermally-Modulated Battery For Electric Cars
schwit1 shares a report from Penn State University: Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium.....»»
Astronomers detect an outbursting young stellar object
By analyzing datasets from the Palomar Gattini InfraRed survey (PGIR) and NASA's NEOWISE spacecraft, astronomers have identified an outbursting young stellar object (YSO) in the star-forming region NGC 281-W. The study, which reports the finding and.....»»
Samsung"s $30 Galaxy SmartTag tracker works like Tile"s but only with Galaxy phones
Samsung threw its hat in the ring on Thursday to challenge Tile with its object tracking solution, the Galaxy SmartTag. The fob easily attaches to a set of keys or stashes away in a backpack pocket to help users locate their belongings if they lose t.....»»
Astronomers find signature of magnetar outbursts in nearby galaxies
Apart from black holes, magnetars may be the most extreme stars in the universe. With a diameter less than the length of Manhattan, they pack more mass than that of our sun, wield the largest magnetic field of any known object—more than 10 trillion.....»»
What to expect from the first-ever virtual CES
Some big players are missing, along with over half of last year's exhibitors. Enlarge (credit: Subject/Object Manifest | Getty Images) Last year's CES in Las Vegas, Nevada, marked the last time for a long time many of us would be chatting face.....»»
Observations shed more light on the atmosphere of white dwarf GD 424
Astronomers have performed spectroscopic observations of a newly detected white dwarf star known as GD 424. Results of the observational campaign provide more insights into the atmosphere of this object. The study was presented in a paper published D.....»»
Chinese astronomers discover 591 high-velocity stars with LAMOST and Gaia
A research team, led by astronomers from National Astronomical Observatories of Chinese Academy of Sciences (NAOC), has discovered 591 high velocity stars based on data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and G.....»»
Due to Popular Demand, GM May Build More of Its "Hummer EV" Electric Pickups
FrankOVD shares this report from CNET: The people were really into the GMC Hummer EV when the brand finally ripped the cloak off the electric pickup truck earlier this year. So much so that the Hummer EV Edition 1 trim sold out in 10 minutes. Now, G.....»»
Iris Automation raises $13 million for visual drone object avoidance tech
It’s only a matter of time now before drones become a key component of everyday logistics infrastructure, but there are still significant barriers between where we are today and that future – particularly when it comes to regulation. Iris Aut.....»»
