Like something straight out of a pulpy sci-fi horror flick, researchers at Tufts University and the University of Vermont (UVM) have engineered a new generation of living robots they call Xenobots, which demonstrate cooperative swarm activity while collecting piles of micro particles.

Last year, this same team of scientists and biologists created tiny self-healing bio-machines that exhibited movement, payload pushing abilities, and a sort of hive mentality. The blueprints for creating these biological bots, which technically aren’t a typical robot or a catalogued animal species, but instead are more akin to a distinct class of unique artifact that acts as a living, programmable organism.

Bay Area-based Rapid Robotics today announced a $12 million Series A. The new round, led by NEA, brings the company’s total funding up to $17.5 million. It joins a recently closed seed round, announced way back in November of last year. Existing investors Greycroft, Bee Partners and 468 Capital also took part in the round.

We noted at that stage that COVID-19 had a sizable impact on robotics investment. At the very least, the pandemic has served to accelerate interest in automation, as many “non-essential” workers have been unable to travel to their jobs. At present, manufacturing jobs often lack the ability to perform remotely.

Rapid notes that the company’s tech has been involved with the production of some 50 million parts over the past year, over a wide variety of different manufacturing verticals. And, like his predecessor, President Biden has already begun talking up strategies to return manufacturing jobs to the U.S. Of course, ambitious as it might be, any plan is going to have to be a balancing act between human jobs and automation.

Plus, we can bring along 1.5 tons.

Scientists have outlined the wild way humans could travel past Neptune in under 10 years—with over 1.5 tons of cargo on board.

This Trojan is detected as the first that is written in. NET, rather than Delphi. Read on to know more differences.

I just finished the most recent season of The Expanse – my current favourite Sci-Fi series. Unlike most of my other go-to Sci-Fi, The Expanse’s narrative is (thus far) mainly contained to our own Solar System. In Star Trek, ships fly about the galaxy at Faster-Than-Light speeds giving mention to the many light years (or parsecs *cough* Star Wars) travelled to say nothing of sublight journeys within solar systems themselves. The distances between stars is huge. But, for current-day Earthling technology, our Solar System itself is still overwhelmingly enormous. It takes years to get anywhere.

In The Expanse, ships use a fictional sublight propulsion called The Epstein Drive to travel quickly through the Solar System at significant fractions of light speed. We’re not nearly there yet, but we are getting closer with the announcement of a new theoretical sublight propulsion. It won’t be an Epstein drive, but it may come to be known as the Ebrahimi Drive – an engine inspired by fusion reactors and the incredible power of solar Coronal Mass Ejections.

Rocket engines have been the backbone of space exploration lifting humans to the Moon, rovers to Mars, and sending probes outside the Solar System. However, for all their blast-offy awesomeness, they are inherently inefficient and bulky. You can only get so much energy out of rocket fuel. As a result, most of your entire spacecraft is a giant fuel tank. The mass of a rocket destined for Mars could be as much as 78% fuel. To reduce weight, we need more efficient engines.

It’s not the next Higgs boson — yet. But the best explanation, physicists say, involves forms of matter and energy not currently known to science.

Researchers have used a quantum mechanical property to overcome some of the limitations of conventional holograms. The new approach, detailed in Nature Physics, employed quantum entanglement, allowing two photons to become a single “non-local particle.” A series of entangled photon pairs is key to producing new and improved holograms.

Classical holograms work by using a single light beam split into two. One beam is sent towards the object you’re recreating and is reflected onto a special camera. The second beam is sent directly onto the camera. By measuring the differences in light, its phase, you can reconstruct a 3D image. A key property in this is the wave’s coherence.

The quantum hologram shares some of these principles but its execution is very different. It starts by splitting a laser beam in two, but these two beams will not be reunited. The key is in the splitting. As you can see in the image below, the blue laser hits a nonlinear crystal, which creates two beams made of pairs of entangled photons.

In a new study, researchers from Australia and Canada have identified a ‘sweet spot’, using holes, where the qubit is least sensitive to noise.
