The Clever Reason Elon Musk Tweets So Much

Posted by in categories: Elon Musk, sustainability, transportation

When Elon Musk has any news to share, you’re likely to hear about it first on Twitter. You’d think the guy who runs SpaceX, Neuralink, Tesla, The Boring Company wouldn’t have much time on his hands.

But as his companies grow, so do his number of tweets. They’ve been increasing steadily – as the Wall Street Journal notes in this graphic. His tweets are so frequent that when he announced he was taking a break from Twitter that one time, it made the news.

‘Deepfaking the mind’ could improve brain-computer interfaces for people with disabilities

Posted by in categories: information science, robotics/AI

Researchers at the USC Viterbi School of Engineering are using generative adversarial networks (GANs)—technology best known for creating deepfake videos and photorealistic human faces—to improve brain-computer interfaces for people with disabilities.

In a paper published in Nature Biomedical Engineering, the team successfully taught an AI to generate synthetic brain activity data. The data, specifically called spike trains, can be fed into to improve the usability of (BCI).

BCI systems work by analyzing a person’s brain signals and translating that into commands, allowing the user to control like computer cursors using only their thoughts. These devices can improve quality of life for people with motor dysfunction or paralysis, even those struggling with locked-in syndrome—when a person is fully conscious but unable to move or communicate.

Why is quantum theory so strange? The weirdness could be in our heads

Posted by in category: quantum physics

Quantum theory is peerless at explaining reality, but assaults our intuitions of how reality should be. It seems likely the fault lies with our intuitions.

A soft magnetic pixel robot that can be programmed to take different shapes

Posted by in categories: biotech/medical, robotics/AI

Magnetic soft robots are systems that can change shape or perform different actions when a magnetic field is applied to them. These robots have numerous advantageous characteristics, including a wireless drive, high flexibility and infinite endurance.

In the future, micro-scale magnetic soft robots could be implemented in a variety of settings; for instance, helping humans to monitor the environment or to remotely perform biomedical procedures. Most of the systems developed so far, however, can only complete simple tasks and take on a limited number of shapes.

Researchers at the Chinese Academy of Sciences have recently devised a new technique for creating shape-programmable magnetic soft robots. This technique, outlined in a paper pre-published on arXiv and presented at the CCIR2021 conference, allowed them to create a new based on magnetic pixels that can change shapes and complete a variety of actions or tasks.

Little-Known Glial Cells Are Critical Regulators of Heart Development and Function

Posted by in categories: biotech/medical, neuroscience

Discovery suggests glial cells may be important in other organs as well.

Glial cells in the heart help regulate heart rate and rhythm, and drive its development in the embryo, according to a new study publishing today (November 18th, 2021) in the open-access journal PLOS Biology by Nina Kikel-Coury, Cody Smith and colleagues at the University of Notre Dame. The discovery provides the most detailed portrait yet of a critical population of cells that had been previously poorly understood.

Glia are a diverse set of cell types, originally named after the Greek word for glue, and include cells that surround and nourish neurons, and others that mount immune responses within the central nervous system. In the peripheral nervous system, glia are present and presumably active in multiple organs, including the gut, pancreas, spleen, and lungs, although their function is not clear in most cases.

Orion Bar region investigated in detail

Posted by in categories: evolution, space

Using spacecraft and ground-based facilities, Russian astronomers have inspected the Orion Bar photodissociation region, focusing on the mid-infrared emission from this source. Results of the study could help astronomers to better understand the evolution of polycyclic aromatic hydrocarbons in space. The research was published November 10 on arXiv.org.

At a distance of about 1,300 away, the Orion Nebula is the nearest of massive star formation to Earth, with a complex and extensive gas structure. It hosts the so-called “Orion Bar”—a ridge-like feature of gas and dust formed by the intense radiation from nearby, hot, young stars, which appears to be shaped like a bar.

The Orion Bar is a photodissociation region or photon-dominated region (PDR). In general, PDRs are regions in the interstellar medium (ISM) at the interface between hot ionized gas and cool molecular gas that are energetically dominated by non-ionizing ultraviolet photons.
