Questions raised about certification of new nuclear warhead design
The Bush administrattion wants to replace cold war-era nuclear warheads with a newly designed Reliable Replacement Warhead (RRW); trouble is, a 1992 U.S.-Russia treaty imposed a moratorium on all nuclear tests, so the new design cannot be tested

Liquid explosives detection technology is almost here
After the plot to blow up trans-Atlantic airlines with liquid explosives was uncovered in London in August 2006, pressure has grown to find new ways to detect liquids in baggage and on airline passengers and figure out what they are

First true invisibility cloak created
University of Maryland researchers develop first true invisibility cloak; it is still small — well, at 10 micrometres in diameter, very small — and works only in two dimensions, but shows that true invisibility is practicable

Stanford researchers offer revolutionary design for computer chips
Moore’s law stipulates that the number of transistors squeezed onto a computer chip can be doubled about every two years; the law was threteaned by the damaging heat generated by the chips as their transistors become more densely packed; new design solves problem; “What we managed to do is basically get rid of the magnetic field,” says lead researcher

Mechanical mole seeks out disaster survivors under collapsed buildings
Robots already roll, walk, slither, and even “swarm” to locate or help survivors, so why not dig and burrow? University of Manchester rsearchers build a digging robot which imitates the common European mole

Herding swarming robots
Individual autonomous machines are now in wide use on land, in the air, and at sea for defense and homeland security missions; using several of these robots together, in a coordinated fashion, is difficult; an MIT researcher offers a way to use “swarming” robots which talk to each other

To Make Children Better Fact-Checkers, Expose Them to More Misinformation — with Oversight
“We need to give children experience flexing these skepticism muscles and using these critical thinking skills within this online context,” a psychology researcher said.
Social Media Platforms Aren’t Doing Enough to Stop Harmful AI Bots, Research Finds
While artificial intelligence (AI) bots can serve a legitimate purpose on social media — such as marketing or customer service — some are designed to manipulate public discussion, incite hate speech, spread misinformation or enact fraud and scams.
World War I Was the Crucible of Air Power. Ukraine Looks the Same for Drones
We seem to be seeing a new kind of air battle—lower, slower at close quarters and in a physical environment where fighter aircraft cannot intervene affordably or effectively. Could it be that Ukraine is to small unmanned systems what World War I was to aircraft?
Accelerating Clean Energy Geothermal Development on Public Lands
Geothermal energy is one of our greatest untapped clean energy resources on public lands. Replenished by heat sources deep in the Earth, geothermal energy generates electricity with minimal carbon emissions. Interior Department announces new leases and pioneering project approval, and proposes simplified permitting.
Major Lithium Mine Approved in Nevada, Supporting a Domestic Supply of Critical Minerals
Critical minerals are essential building blocks of the modern economy and America’s energy security, from clean energy technologies – like electric vehicle and grid storage batteries and wind turbines – to semiconductors to advanced defense systems and consumer electronics.
Revising the Cost of Climate Change
Climate scientists have warned of calamitous consequences if global temperatures continue their rise. But macroeconomists have largely told a less alarming story, predicting modest reductions in productivity and spending as the world warms. Until now. New study of economic toll yields projections ‘six times larger than previous estimates’.
