Regulate armed robots before it's too late
Unmanned machines now carry out more and more military and police missions; soon these robots will be allowed to make autonomous life-and-death decisions: when to shoot — and at whom; a philosopher argues that we should be more mindful of the ethical implications of this trend

New design allows for using less steel in concrete beams
NC State researchers discover how to use 30 percent less reinforcing steel in the manufacture of the concrete beams; the success of the project is already drawing interest from the concrete industry

New anti-crime approach: vigilant windows
Windows are coated with special polymer which contains nanoparticles that convert light into fluorescent radiation; this radiation is channeled to the edges of the window where it is detected by sensors; when a person approaches the window, the sensors wirelessly relay this currency information to a computer program, which alerts security officials of the potential intruder

Beads behavior may help in avalanche prediction
Scientists blame the seeming impossibility of predicting the next big avalanche or earthquake on the inherent unpredictability of complex systems; a unique experiment, however, suggests that this idea may be wrong

New reactor design solves waste, weapon proliferation problems
A new nuclear reactor design — called Traveling-Wave reactor — is noteworthy for three things: it comes from a privately funded research company, not the government; it would run on what is now waste, thus reducing dramatically the nuclear waste and weapon proliferation problems; and it could theoretically run for a couple of hundred years without refueling

Economists: copyright and patent laws killing innovation, hurting economy
Two Washington University researchers argue that innovation is key to reviving the economy; trouble is, the current patent/copyright system discourages and prevents inventions from entering the marketplace

Economists: Markets outperform patents in promoting intellectual discovery
Researchers say that the problem with patents is that they give the prize to the winner only; whoever comes in second or third walks away empty-handed; allowing people to benefit even if they only tackle a part of a problem might well lead to more collaboration, and to the faster development of an ultimate solution to the whole problem

Researchers develop plutonium which is good for power but not for weapons
Israeli researcher finds that adding the rare-earth isotope Americium-241 in due proportion during reprocessing “declaws” plutonium, making suitable for power generation but not for weapons

Ejector-seat ambulance design
U.K. design students produce a novel concept: an ambulance with ejector seats; when paramedics arrive on the scene of the disaster, they and their equipment are “hurled” toward the victims to ensure faster treatment

U.S. military is looking for all-in-one triggering device
At present, soldiers wishing to blow something up usually have to assemble firing circuits, electronics, detonators, and main charges in the field — or, at any rate, lash them together with gaffer tape and so forth prior to parachuting, submarining, or helicoptering into action; Pentagon research arm want a better way of triggering an explosive

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
