Recently, a team of South Korean scientists led by Director C. Justin Lee of the Center for Cognition and Sociality within the Institute for Basic Science made a discovery that could revolutionize both the diagnosis and treatment of Alzheimer’s Disease. The group demonstrated a mechanism where the astrocytes in the brain uptake elevated levels of acetates, which turns them into hazardous reactive astrocytes. They then went on to further develop a new imaging technique that takes advantage of this mechanism to directly observe the astrocyte-neuron interactions.

Alzheimer’s disease (AD), one of the major causes of dementia, is known to be associated with neuroinflammation in the brain. While traditional neuroscience has long believed that amyloid beta plaques are the cause, treatments that target these plaques have had little success in treating or slowing the progression of Alzheimer’s disease.

On the other hand, Director C. Justin Lee has been a proponent of a novel theory that reactive astrocytes are the real culprit behind Alzheimer’s disease. Reactive astrogliosis, a hallmark of neuroinflammation in AD, often precedes neuronal degeneration or death.

In the brains of people without schizophrenia, concepts are organized into specific semantic domains and are globally connected, enabling coherent thought and speech.

In contrast, the researchers reported that the semantic networks of people with schizophrenia were disorganized and randomized. These impairments in semantics and associations contribute to delusion and incoherent speech.

Lithium-ion batteries power our lives.

Because they are lightweight, have and are rechargeable, the batteries power many products, from laptops and cell phones to electric cars and toothbrushes.

However, current have reached the limit of how much energy they can store. That has researchers looking for more powerful and cheaper alternatives.

Researchers in Carnegie Mellon University’s Robotics Institute (RI) have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam—a feat that is likely the first of its kind.

“This experiment was huge,” said Zachary Manchester, an assistant professor in the RI and head of the Robotic Exploration Lab. “I don’t think anyone has ever successfully done balance beam walking with a before.”

To the team’s knowledge, this is the first instance of a successfully walking on a narrow balance beam. Their paper, “Enhanced Balance for Legged Robots Using Reaction Wheels,” was accepted to the 2023 International Conference on Robotics and Automation. The annual conference will be held May 29–June 2, in London.

An instrument on the International Space Station has revealed new information about how the Sun’s magnetic field affects cosmic rays on their way to Earth.

Galactic cosmic rays (GCRs) are highly energetic charged particles that are produced through various acceleration mechanisms in astrophysical objects such as supernova remnants. These particles propagate through the Galaxy and can reach the heliosphere, a region dominated by plasma originating from the Sun. Within the heliosphere, GCRs interact with the turbulent plasma environment in a way that decreases their flux, causing them to diffuse in space and to lose energy [1]. Most of the impact of this “solar modulation” on GCRs is independent of particle charge. But GCR drift is also influenced by large-scale gradients in, and curvatures of, the heliospheric magnetic field and by the current sheet—a tenuous structure that separates the heliosphere into regions of opposite magnetic-field polarity [2].

To build a workforce that can meet the expected future demand in the quantum sector, we need to train many more quantum-literate educators and marshal support for them.

In 2018 the US federal government passed the National Quantum Initiative Act, a program designed to accelerate the country’s quantum research and development activities. In the next decade, quantum information science and quantum technologies are expected to have a significant impact on the US economy, as well as on that of other countries. To fulfill that promise, the US will need a “quantum-capable” workforce that is conversant with the core aspects of quantum technologies and is large enough to meet the expected demand. But even now, as quantum-career opportunities are just starting to appear, supply falls behind demand; according to a 2022 report, there is currently only around one qualified candidate for every three quantum job openings [1]. We call for education institutions and funding agencies to invest significantly in workforce development efforts to prevent the worsening of this dearth.

Most of today’s jobs in quantum information science and technology (QIST) require detailed knowledge and skills that students typically gain in graduate-level programs [2]. As the quantum industry matures from having a research and development focus toward having a deployment focus, this requirement will likely relax. The change is expected to increase the proportion of QIST jobs compatible with undergraduate-level training. However, 86% of QIST-focused courses currently take place at PhD-granting research institutions [3]. Very few other undergraduate institutions offer opportunities to learn about the subject. To meet the future need, we believe that aspect needs to change with QIST education being incorporated into the curricula at predominantly undergraduate institutions and community colleges in the US. However, adding QIST classes to the curricula at these institutions will be no easy task.
