Moscow Metro launches pay per face recognition | DW News

Posted by in categories: privacy, robotics/AI

Passengers on the Moscow metro can now pay for their commute using facial recognition technology. The system is called “Face Pay” — and connects passengers’ biometric data with their credit cards.
It’s been rolled out across all 241 stations in the Russian capital — but privacy activists are sounding the alarm.

UK to launch space missions from Scotland next year

Posted by in category: space

This is the first agreement Skyrora has made with a Scottish Spaceport. If successful, this could be the first commercial rocket to go to space from the UK.

The multi-launch agreement with SaxaVord will run for the next decade, giving Skyrora the ability to build towards their target of 16 launches a year by 2030.

#Skyrora is delighted to announce we’ve officially signed an LOI to launch our orbital vehicle, #SkyroraXL, from @Saxavord_Space at the end of 2022!

VanMoof unveils 31 mph ‘hyperbike’ electric bicycle with two motors and full suspension

Posted by in category: transportation

VanMoof has just announced a new high-speed electric bicycle model known as the VanMoof V, which will reach speeds of up to 31 mph (50 km/h). The company is referring to it as a “hyperbike,” which makes sense considering it is faster than just about any other e-bike available in the US or Europe.

VanMoof is largely known as an elegant, tech-forward electric bicycle brand. The Dutch company’s sleek, classy-looking e-bikes are heavy on the tech side but don’t attempt to win any awards on performance.

That makes today’s announcement of a high-speed electric bicycle all the more suprising.

How solar rockets can bring Uber to Musk’s Mars city

Posted by in categories: satellites, solar power, sustainability

One emergent company, Virgin Orbit wants to switch from a fuel-burning upper stage to solar energy, a move that could support future human habitats on other planets.

The satellite launch company has made a name for itself with its visually striking rocket launches. Strapped to the wing of a Boeing 747 the LauncherOne rocket doesn’t need the same launch pads and infrastructure as its competitors.

Ex-SpaceX Engineers Are Building a Cheap, Portable Nuclear Reactor

Posted by in categories: military, nuclear energy

Nuclear power is going portable in the form of relatively lightweight, cost-effective microreactors. A team of former SpaceX engineers is developing the “world’s first portable, zero-emissions power source” that can bring power to remote areas and also allows for quick installation of new units in populated areas, a press statement revealed.

Last year, the team secured $1.2 million in funding from angel investors for their startup Radiant to help develop its portable nuclear microreactors, which are aimed at both commercial and military applications.

Surprise: the Big Bang isn’t the beginning of the universe anymore

Cooling radio waves to their quantum ground state

Posted by in categories: biotech/medical, quantum physics

Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use in detecting ultra-weak magnetic resonance (MRI) signals or for quantum-sensing applications that can help the search for dark matter. The results have been published in Science Advances.

The radio waves we usually encounter in our daily lives, such as those that we listen to in our car or those that send signals to our baby monitors in our house, are hot: they contain noise that comes from the random motion of the in the things they are emitted from and even in the antenna you are using to listen to them. This is one of the reasons why you hear static when you tune the radio in your car to a frequency that has no .

Virtual reality: A front-row seat to the impact of (un)sustainable behavior

Posted by in categories: sustainability, virtual reality

Witness first-hand how your mountain of waste plastic expands over the years and what impact your food has on the rainforests. Virtual reality gives you a front-row seat to the impact of unsustainable behavior. Communication scientists Marijn Meijers and Hande Sungur have developed highly effective virtual worlds that give people an up-close and personal experience of how sustainable and unsustainable conduct make a substantial difference…


You walk around a supermarket and whenever you take a product from the shelves, a pop-up appears with information about the environmental impact of your choice, for example, clearcutting of tropical rainforest to cultivate the palm oil in your chocolate spread. You travel through time to see how much plastic waste your everyday products create in the future, and travel back to see how your mountain of waste shrinks when you make more sustainable decisions.

VR is shown to have a positive effect on sustainability.
