Quantum systems hold the promise of tackling some complex problems faster and more efficiently than classical computers. Despite their potential, so far only a limited number of studies have conclusively demonstrated that quantum computers can outperform classical computers on specific tasks. Most of these studies focused on tasks that involve advanced computations, simulations or optimization, which can be difficult for non-experts to grasp.
Researchers at the University of Oxford and the University of Sevilla recently demonstrated a quantum advantage over a classical scenario on a cooperation task called the odd-cycle game. Their paper, published in Physical Review Letters, shows that a team with quantum entanglement can win this game more often than a team without.
“There is a lot of talk about quantum advantage and how quantum systems will revolutionize entire industries, but if you look closely, in many cases, there is no mathematical proof that classical methods definitely cannot find solutions as efficiently as quantum algorithms,” Peter Drmota, first author of the paper, told Phys.org.
Twenty-four stroke patients have already used the complete system, consisting of an exoskeleton for the arm and shoulder in combination with FES as part of the ReHyb research project. Half of them were patients at the Schön Klinik Bad Aibling Harthausen, which is leading the study. The researchers also used a computer game that automatically adapts to the individual player’s capabilities. It trains them to grip and move their arms shortly after a stroke by reacting to colored balls flying toward them at varying speeds on a screen. The task is to catch the balls and match them with color-coded boxes.
At the center of TUM Professor Sandra Hirche’s setup is a digital twin that records the individual requirements of each patient and places them in a control loop. Among other things, the researchers have to determine how well each patient can move their arm and hand. In the event of a stroke, for example, paralysis can be caused by damage to the motor area in the brain responsible for movement. However, it is impossible to predict how severely the signals transmitted from the brain to the muscles in the forearm will be impaired after the stroke. “Individual muscle strands in the forearm can be stimulated to the right extent for hands and fingers to move,” says Prof. Hirche, who holds the Chair of Information-Oriented Control at TUM. In addition to information on muscle activity in the forearm, the researchers need to know how strongly the muscles should be stimulated in conjunction with the exoskeleton assistance.
Growing functional human organs outside the body is a long-sought “holy grail” of organ transplantation medicine that remains elusive. New research from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Wyss Institute for Biologically Inspired Engineering brings that quest one big step closer to completion.
A team of scientists created a new method to 3D print vascular networks that consist of interconnected blood vessels possessing a distinct “shell” of smooth muscle cells and endothelial cells surrounding a hollow “core” through which fluid can flow, embedded inside a human cardiac tissue. This vascular architecture closely mimics that of naturally occurring blood vessels and represents significant progress toward being able to manufacture implantable human organs. The achievement is published in Advanced Materials .
Multiple tumour-agnostic kinase inhibitors have been approved that are clinically effective regardless of tumour location. This Review describes the origins of tumour-agnostic drug development, focusing on small-molecule inhibitors that target kinase pathway aberrations, and discusses the challenges in developing tissue-agnostic agents.
Glial replication and proliferation support JC virus demyelination.
In HIV infected patients, JC virus (JCV) can cause a devastating demyelinating disease of the CNS known as progressive multifocal leukoencephalopathy (PML).
JCV replicates in human glial progenitor cells and astrocytes, which undergo viral T-antigen-triggered mitosis, enabling viral replication.
The authors were able to demonstrate that dividing human astrocytes supported JCV propagation to a substantially greater degree than did mitotically quiescent cells.
They also show that JCV infection greatly accentuated by cuprizone-induced demyelination and its associated mobilization of glial progenitor cells and triggered the death of both uninfected and infected glia, reflecting significant bystander death. https://sciencemission.com/JCV-infection-models
This scientific commentary refers to ‘JC virus spread is potentiated by glial replication and demyelination-linked glial proliferation’ by Li et al. (https://doi.org/10.1093/brain/awae252).

A technology developed by the Brazilian company brain4care has been shown to be able to measure absolute values of intracranial pressure (ICP) more accurately than existing non-invasive methods. This is the result of a study published in the journal npj Digital Medicine by researchers from the University of São Paulo in Brazil, the University of Cambridge in the United Kingdom, Emory University in the United States, and the company itself.
“The study included the largest number of patients and showed that the technology we developed had the lowest error in estimating the value of intracranial pressure among all the non-invasive methods already available in the world,” Gustavo Frigieri, scientific director of brain4care and one of the authors of the study, told Agência FAPESP.
The technology developed by the Brazilian company consists of a sensor placed on the patient’s head that registers the nanometric expansions of the skull in each cardiac cycle and generates, in real time, a wave that indicates the variations in volume and intracranial pressure. The data obtained are processed by an artificial intelligence platform that generates reports to help doctors make decisions.
