Packing more energy into batteries is the key to delivering electric cars with longer range, smartphones that can last days—and cheaper electronic products all around.

The promise: Lithium-oxygen batteries represent one of the more promising paths toward that end. They could boost energy density by an order of magnitude above conventional lithium-ion batteries—in theory, at least. In a paper published today in Science, researchers at the University of Waterloo identified ways of addressing some of the major hurdles to converting that potential into commercial reality.

The challenge: A critical problem has been that as a lithium-oxygen battery discharges, oxygen is converted into superoxide and then lithium peroxide, reactive compounds that corrode the battery’s components over time. That, in turn, limits its recharging ability—and any real-world utility.

The facial recognition technology the US is testing for airports has caught its first imposter merely three days after Washington Dulles International started using it. According to US Customs and Border Protection (CBP), a 26-year-old man from Sao Paulo, Brazil successfully fooled people with a French passport until he presented it to a Dulles officer who used the new facial comparison biometric technology. The system determined that his face wasn’t a match with the person in the passport, and he was sent for a comprehensive check, which revealed the Republic of Congo ID hidden inside his shoe.

Materials can deform plastically along atomic-scale line defects called dislocations. Many technical applications such as forging are based on this fundamental process, but the power of dislocations is also exploited in the crumple zones of cars, for instance, where dislocations protect lives by transforming energy into plastic deformation. FAU researchers have now found a way of manipulating individual dislocations directly on the atomic scale.

Using advanced in situ electron microscopy, the researchers in Prof. Erdmann Spiecker’s group have opened up new ways to explore the fundamentals of plasticity. They have published their findings in Science Advances.

Russia’s most famous weapons manufacturer has unveiled a 13ft tall walking killer robot operated by pilots who sit inside it.

Kalashnikov Concern presented the state-of-the-art bulletproof robot along with utility vehicles and new assault rifles at the Army 2018 fair at the Patriot Park just outside Moscow.

One of the most significant AI milestones in history was quietly ushered into being this summer. We speak of the quest for Artificial General Intelligence (AGI), probably the most sought-after goal in the entire field of computer science. With the introduction of the Impala architecture, DeepMind, the company behind AlphaGo and AlphaZero, would seem to finally have AGI firmly in its sights.

Let’s define AGI, since it’s been used by different people to mean different things. AGI is a single intelligence or algorithm that can learn multiple tasks and exhibits positive transfer when doing so, sometimes called meta-learning. During meta-learning, the acquisition of one skill enables the learner to pick up another new skill faster because it applies some of its previous “know-how” to the new task. In other words, one learns how to learn — and can generalize that to acquiring new skills, the way humans do. This has been the holy grail of AI for a long time.

Alt-aviation wizard Burt Rutan set out to design a plane that could haul rockets to the edge of space. Then he persuaded Microsoft cofounder Paul Allen to build a dual-fuselage beast with a wingspan longer than a football field.

Just like the way that cellphones used to be only for the rich, soon the idea of taking a personal flying machine to work is going to be a part of everyday life. Don’t believe us? Here are six examples of personal flying cars and even a personal jetsuit that will help us commute.

Our freeways and highways could really use this. What do you think?

In astronomy, cutting-edge technology often begins with a bunch of bulldozers, busted rocks, and dump trucks.

So it goes with the Giant Magellan Telescope (GMT), which will be the world’s largest and most powerful when it sees “first light” in 2024. Astronomers hope to use the huge observatory to study the ancient universe and look for signs of alien life.

Construction crews atop a Chilean mountain range broke ground for the $US1 billion project on Tuesday.
