Scientist Says Astronauts Should Take Psychedelic Mushrooms in Space

In the future, when space agencies start to send human crews deep into space to explore or terraform distant worlds, we may need to send them off with extra goodies to keep morale high. When astronauts are feeling lonely, depressed, traumatized, or just generally bad, a little pick-me-up in the form of psychedelic mushrooms could help, mycologist Paul Stamets suggested to Scientific American.

With Millennials Renting Homes Like Crazy, It's a Great Time To Buy Rental Property

Wondering if it's a good idea to buy rental property? You definitely should be. Single-family rental properties have always made outstanding investments. But right now, with a huge population of Millennials coming of age and starting their own households, this asset class is stronger than ever. Anyone looking to grow their wealth and build that nest egg needs to take advantage of this opportunity. The only question is, what's the best way to go about doing that?

Running quantum software on a classical computer

Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning algorithm that closely mimics the behavior of near-term quantum computers.

Artificial stomach reveals fluid dynamics of food digestion

In efforts to fight obesity and enhance drug absorption, scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how the complex flow patterns and mechanical stresses produced in the stomach contribute to digestion.

Mott insulator exhibits a sharp response to electron injection

In a finding that will give theorists plenty to ponder, an all-RIKEN team has observed an unexpected response in an exotic material known as a Mott insulator when they injected electrons into it. This observation promises to give physicists new insights into such materials, which are closely related to high-temperature superconductors.

New viable means of storing information for quantum technologies?

Quantum information could be behind the next technological revolution. By analogy with the bit in classical computing, the qubit is the basic element of quantum computing. However, demonstrating the existence of this information storage unit and using it remains complex, and hence limited. In a study published on 3 August 2021 in Physical Review X, an international research team consisting of CNRS researcher Fabio Pistolesi1 and two foreign researchers used theoretical calculations to show that it is possible to realize a new type of qubit, in which information is stored in the oscillation amplitude of a carbon nanotube.

Built-in vibration control may help soundproof spaces

A different kind of design for absorbing vibrations could help better soundproof walls and make vehicles more streamlined, a new study shows.

Acquisition of channel state information for mmWave MIMO: Traditional and machine learning approaches

Millimeter wave (mmWave) communications have attracted extensive interest from academia, industry, and government as they can make full use of abundant frequency resources at the high-frequency band to achieve ultra-high-speed data transmission. The mmWave communication systems are usually equipped with large antenna arrays, known as mmWave massive multiple-input multiple-output (MIMO), to generate highly directional beams and compensate for the severe path loss in the high frequency band. However, the performance of directional beamforming largely relies on the accuracy of channel state information (CSI) acquisition. Compared to the traditional MIMO systems, the CSI acquisition in mmWave massive MIMO systems is challenging. On one hand, the large antenna arrays form a high dimension channel matrix, whose estimation consumes more resources, e.g., pilot sequence overhead, sounding beam overhead, and computational complexity. On the other hand, the mmWave massive MIMO typically employs a hybrid beamforming architecture, where the radio frequency (RF) chains are much fewer than the antennas. Therefore, we can only obtain a low-dimension signal from the RF chains instead of directly getting a high-dimension signal from the frontend antennas, which makes CSI acquisition much more challenging than usual.

Vapor-collection technology saves water while clearing the air

About two-fifths of all the water that gets withdrawn from lakes, rivers, and wells in the U.S. is used not for agriculture, drinking, or sanitation, but to cool the power plants that provide electricity from fossil fuels or nuclear power. Over 65 percent of these plants use evaporative cooling, leading to huge white plumes that billow from their cooling towers, which can be a nuisance and, in some cases, even contribute to dangerous driving conditions.
