“As several people mention in the replies to LenKusov, shooting or otherwise damaging that hefty lithium battery pack could make it explode—which is either very bad if you’re close-range, or exactly what you want if you’re somehow hitting it from a distance and trying for fireworks.”
It turns out that a flip through Spot’s user manual reveals its weaknesses.
Something completely logical. I’ve always wondered why these vehicles haven’t been designed to use the energy that wheel rotation produces to charge the batteries of the vehicle.
This month is a time to celebrate. CERN has just announced the discovery of four brand new particles at the Large Hadron Collider (LHC) in Geneva.
This means that the LHC has now found a total of 59 new particles, in addition to the Nobel prize-winning Higgs boson, since it started colliding protons – particles that make up the atomic nucleus along with neutrons – in 2009.
Excitingly, while some of these new particles were expected based on our established theories, some were altogether more surprising.
There’s more AI news out there than anyone can possibly keep up with. But you can stay tolerably up to date on the most interesting developments with this column, which collects AI and machine learning advancements from around the world and explains why they might be important to tech, startups or civilization.
To begin on a lighthearted note: The ways researchers find to apply machine learning to the arts are always interesting — though not always practical. A team from the University of Washington wanted to see if a computer vision system could learn to tell what is being played on a piano just from an overhead view of the keys and the player’s hands.
Audeo, the system trained by Eli Shlizerman, Kun Su and Xiulong Liu, watches video of piano playing and first extracts a piano-roll-like simple sequence of key presses. Then it adds expression in the form of length and strength of the presses, and lastly polishes it up for input into a MIDI synthesizer for output. The results are a little loose but definitely recognizable.
Uber and OpenAI researchers say an advance in Go-Explore AI in beating Atari games could have applications for robotics and drug design.
A new laser thruster could be a step towards new technology to push satellites rapidly between planets.
The demonstration model of the Photonic Laser Thruster (PLT) moved a 750-gram mock satellite along a track in the laboratory using only the power of light.
Volunteer students at Beihang University have reportedly lived in the Lunar Palace 1 biosphere environment for 370 days. Media outlets have reported that two groups of students took turns living in the biosphere over the course of 370 days, and required minimal supplies from the outside.
Many groups have tried building and living in biospheres over the years. The goal has always been to find out if it is possible to build a self-sustaining ecosystem that could be used on another planet. The most well-known was Biosphere 2—it was built in the Arizona desert and hosted people for two years, but ultimately failed in its goal to remain self-supporting. However, such efforts have led to a better understanding of how a real biosphere might work and how plants might be grown beyond Earth.
Over the past several years, the Chinese government has made it clear that they plan to send people to the moon in the coming years. They also plan to build a permanent colony there, to be shared with other countries, as soon as it is feasible. As part of that effort, they have been planning, building and testing biospheres since 2014. In 2017, they finished construction of the Lunar Palace 1 biosphere. Once set up and tested, four volunteers entered the facility and stayed for 110 days. Shortly thereafter, another group moved into the biosphere and stayed for 65 days—they were replaced immediately by another team who spent 200 days in the test environment. That team was then replaced by the first team, which spent an additional 105 days in the facility. Altogether, the two groups spent 370 consecutive days in the biosphere.
A former graduate student reflects on how Isadore Singer, who died on February 11, brought together mathematicians, physicists and anyone else interested in the deeper connections between diverse fields.
Astronomers using data from the eROSITA X-ray telescope aboard the Spektrum-Roentgen-Gamma (SRG) observatory have detected the largest supernova remnant ever discovered with X-rays.
Have you ever heard of “Allostatic Load” and “Operator Syndrome?”
I stumbled across the work of Christopher Frueh while doing some research on physiological, psychological and hormonal stress mitigation. Frueh, along with his team of researchers, psychologists and former SOF operators, has been exploring the human mind, defining PTSD and outlining Special Operator’s Syndrome. This is one of the only programs in the country specifically designed to help those suffering from this condition.
“Allostatic load” is the cost on your body of chronic stress and physical demands of a career with the military special forces, according to Science Direct. The military recipe for “burning the candle at both ends” includes high intensity physical fitness training, the high stress of operations and being away from home, the trauma of witnessing death, war or injury. Add in the inability to sleep or eat well, and the operator limits the two main recovery responses, which leads to chronic stress. This adds up to Allostatic Overload.
