Immunotherapy after stem cell transplantation effectively combats certain childhood nerve tumors

Posted by in category: biotech/medical

Scientists at St. Anna Children’s Cancer Research Institute and the Eberhard Karls University of Tübingen have shown that immunotherapy after stem cell transplantation effectively combats certain nerve tumors in children. Crucially, stem cells from a parent provide children with a new immune system that responds much better to immunotherapies. These results of an early clinical trial were published in the prestigious Journal of Clinical Oncology.

Childhood tumors of the nervous system, known as neuroblastomas, are associated with an unfavorable prognosis if the tumor is classified as a high-risk type. The chances are particularly poor for patients in the relapsed stage. In this case, immunotherapy following stem cell transplantation is now associated with long-term survival in a substantial proportion of the patients included in a recent study. Compared to an earlier study the survival rate was increased.

After the transplantation of stem cells from a parent, the patients are equipped with a new immune system. This enables a better immune response to the subsequent immunotherapy and clearly improves the outcome,” explains Prof. Ruth Ladenstein, MD, head of the Studies & Statistics group for Integrated Research and Projects (S2IRP) at St. Anna Children’s Cancer Research Institute and professor at the Department of Pediatrics and Adolescent Medicine at MedUni Vienna, who played a key role as co-first author.

New fuel cell architecture uses nanowires to deliver durability

Posted by in categories: economics, life extension, nanotechnology

A promising, more durable fuel cell design could help transform heavy-duty trucking and other clean fuel cell applications. Consisting of nanowires that are less susceptible to corrosion than other designs, the innovative electrode—the heart of a polymer electrolyte-membrane fuel cell—could usher in a new era for fuel cells, which use hydrogen as emission-free power for vehicles.

“In real-world terms, this means that we can have a more durable fuel cell that will provide high fuel economy over a longer lifetime,” said Jacob Spendelow, a scientist with the Los Alamos National Laboratory team that described its results in the journal Advanced Materials. “This work demonstrates that we can get rid of conventional carbon-based catalyst supports, eliminating the degradation problems associated with carbon corrosion, while still achieving high fuel cell performance.”

The improved durability makes this fuel cell a promising candidate for use in heavy-duty trucking applications, which require fuel cell lifetimes of more than 25,000 hours.

Long distance entanglement and high-dimensional quantum teleportation in the Fermi–Hubbard model

Posted by in category: quantum physics

Teleportation year 2023 😗😁.


The long distance entanglement in finite size open Fermi–Hubbard chains, together with the end-to-end quantum teleportation are investigated. We show the peculiarity of the ground state of the Fermi–Hubbard model to support maximum long distance entanglement, which allows it to operate as a quantum resource for high fidelity long distance quantum teleportation. We determine the physical properties and conditions for creating scalable long distance entanglement and analyze its stability under the effect of the Coulomb interaction and the hopping amplitude. Furthermore, we show that the choice of the measurement basis in the protocol can drastically affect the fidelity of quantum teleportation and we argue that perfect information transfer can be attained by choosing an adequate basis reflecting the salient properties of the quantum channel, i.e. Hubbard projective measurements.

Photons Crash Into Each Other—on a Time Mirror

Posted by in category: futurism

Scientists have designed a fundamentally new way to make light beams collide with each other—by reflecting them both on the same mirror in time. The team also showed off the beam-shaping capabilities of their technique, with possible applications in telecommunications and scientific measurement.

A particular way of creating quantum entanglement may improve accuracy of advanced quantum sensors

Posted by in categories: particle physics, quantum physics, satellites

Metrological institutions around the world administer our time using atomic clocks based on the natural oscillations of atoms. These clocks, pivotal for applications like satellite navigation or data transfer, have recently been improved by using ever higher oscillation frequencies in optical atomic clocks.

Now, scientists at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences led by Christian Roos show how a particular way of creating entanglement can be used to further improve the accuracy of measurements integral to an optical atomic clock’s function. Their results have been published in the journal Nature.

Observations of are always subject to a certain statistical uncertainty. “This is due to the nature of the quantum world,” explains Johannes Franke from Christian Roos’ team. “Entanglement can help us reduce these errors.”

Meteor fragments came from another solar system, says Avi Loeb

Posted by in category: space

When the meteor that Avi Loeb, director of the Institute for Theory and Computation at Harvard University calls IM1 streaked across the sky on 8 January 2014, it was nothing special.

Yes, at half a meter in diameter, it was big enough to put on a nice show for people on the ground, ending in a rapid series of explosions high in the atmosphere.

“There were some reports of flashes in the sky, and there was probably a boom, although I’ve never heard anyone say that,” says Loeb’s colleague, Rob McCallum of Cambridge, Massachusetts.
