I guess humans aren’t the only ones getting the boot.🤣

According to a Wired report, Alphabet’s ‘Everyday Robots’ project — an unit under Google’s experimental X laboratories — has been shut down by Google CEO Sundar Pichai. It had trained 100 one-armed, wheeled robots to help clean the company’s cafeterias. Several of these robot prototypes were transported out of the lab and were doing useful duties throughout Google’s Bay Area facilities.

Classical chaos – or the butterfly effect – produces fractal patterns like the one shown. Classical chaos’s cousin – quantum information scrambling – encompasses even more exotic mechanisms such as quasiparticles hopping between molecules, which can dissipate energy.

At present, scientists study gravitational fields passively. They observe and try to understand existing gravitational fields produced by large inertial masses such as stars or planets, without being able to change them, as with magnetic fields. It was this frustration that led Füzfa to attempt a revolutionary approach: creating gravitational fields at will from well-controlled magnetic fields and observing how these magnetic fields could bend space-time.
In his article, Füzfa has proposed, with supporting mathematical proof, a device with which to create detectable gravitational fields. This theoretical device is based on superconducting electromagnets and therefore relies on technologies routinely used, for example, at CERN or the ITER reactor.

Simulations show that nonlinear spacetime dynamics manifest in the postmerger gravitational-wave signal of binary black hole coalescence.
“Spacetime tells matter how to move; matter tells spacetime how to curve.” This statement by physicist John Wheeler captures a defining feature of general relativity: its prediction of nonlinear spacetime dynamics. Such nonlinear evolution should be most evident in energetic spacetime events such as merging black holes, prompting the question of whether we can test for it using observations of gravitational waves emitted during such mergers. Two independent teams, led by Keefe Mitman at the California Institute of Technology [1] and Mark Ho-Yeuk Cheung at Johns Hopkins University in Maryland [2], show that this is the case. Using numerical simulations, they show the presence of nonlinearity in postmerger gravitational-wave signals.
Two teams demonstrate an innovative way to measure the states of spin-based qubits—a key task in quantum computing.
Researchers predict that the “scattering matrix” of a collection of particles could be used to slow the particles down, potentially allowing for the cooling of significantly more particles than is possible with current techniques.
When light travels through an environment containing many particles, information about the collective motion of the particles gets added to the light. This information leaves a measurable signature on a quantity known as the scattering matrix. Now researchers from the Vienna University of Technology predict that the information in this matrix could be used to alter the speeds of the particles [1, 2]. The team says that, if experimentally realized, the technique could allow scientists to study the collective quantum behavior of more particles than is possible with current techniques.
Researchers have long been fascinated with using light to slow down or even freeze the motion of a collection of particles. One motivation is that cooled particles can be isolated from outside influences in order to study quantum behaviors such as entanglement. To date, researchers have simultaneously cooled one or two particles, but they have struggled to scale techniques to cool additional particles.
Anxiety disorders are becoming increasingly common, with estimates suggesting that almost one in three people in the U.S. will experience high levels of anxiety at some point in their life. Anxiety is essentially a feeling of unease, worry or psychological discomfort, typically associated with catastrophic thoughts about a real or imagined future life event.
When they are anxious, humans experience the same sensations and physiological responses they would feel when they are afraid of a real and immediate threat, such as a lion chasing them, an ongoing natural disaster, and so on. To better support patients with anxiety disorders, neuroscientists and psychology researchers have been trying to understand the neural underpinnings of fear and anxiety for many years.
Ultimately, both fear and anxiety tend to promote defensive behaviors in response to real or imaginary threats, respectively. The most widely documented among these are the so-called freeze (i.e., staying still), flight (i.e., avoiding a feared situation or escaping), fight (i.e., arguing or becoming aggressive) and fawn (i.e., overpleasing or submitting to another human to avoid the escalation of conflict).
