Cutting edge CAR-T cell therapy drives remission of three life-threatening autoimmune diseases in patient.
Med by Cell Press.
This single-patient case report expands the indications in which CD19 CAR-T cell therapy demonstrates unprecedented clinical efficacy, achieving sustained, treatment-free remission. Following B cell abrogation, AIHA is stopped, antiphospholipid antibodies are abrogated, and an underlying ITP is stabilized without any CAR-typical side effects.
Frank Herbert’s Dune saga which has six books in its expanse is no doubt one of the most popular and most influential books in Science fiction. Dune is really about how putting all your hope into a hero or a “chosen one” and then to a set of beliefs can go awry wrong in a big terrifying way. The story shows how easily large groups of people can be influenced by ideas, especially when religion and politics get mixed together, it shows the great game of power on a galactic scale. It showcases how humanity would evolve and transform in the future, some which are familiar while others totally alien in appearance. Then the overall idea of a long “Golden Path” that is meant to ensure the survival of humanity becomes the overarching theme of the saga and along the way, different human types emerge in the storyline, some enhanced by genetic engineering, others by cloning and selective breeding. So, here in this video we will take a look at 10 of these enhanced or superhuman types in the canon Dune works.

Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing dream—the direct interaction with the microscopic world.
Particularly relevant are biological objects in aqueous environments, such as single cells or bacteria. Handling such objects in a controlled and targeted way has remained a major challenge.
A team of researchers have demonstrated how such microscopic cleaners can be employed and precisely controlled. The study is published in the journal Nature Communications. The nanorobots presented demonstrate that controlled manipulation, including collection and relocation of bacteria, is already achievable.
The default mode network (DMN) is a distributed set of interconnected brain regions that has long been associated with internally oriented cognition, such as remembering the past, thinking about the future, or thinking about oneself. Accumulating evidence also indicates that the DMN is engaged during tasks involving external perceptual input, such as language comprehension and social perception. However, the mechanism by which the same network supports both internally and externally oriented cognition has remained unknown.
Now, a research team led by Zhang Meichao from the Institute of Psychology of the Chinese Academy of Sciences (CAS) has identified an organizational principle within the DMN that helps explain how the network supports both internal and external cognition.
The study, published in PNAS, reveals that distinct subregions within the DMN act as “senders” and “receivers” of information, enabling flexible shifts between perception and memory-driven thought.
Macrophages, much like Alice of “Alice in Wonderland,” recognize and consume tumor cells that display “eat me” surface markers. However, tumor cells can evade detection by macrophages if they successfully present “don’t eat me” signals.
The team conducted a genome-scale loss of function screen in AML cell lines, systematically turning off individual genes and cataloging those that affected detection by macrophages.
Surprisingly, the classic CD47 “don’t eat me” signal had only a weak effect. Instead, the researchers found that another signal—CD43—had a much stronger influence on macrophage detection.
The inhibitory activity of CD43 was dependent on its sialic acid residues and the length of its ectodomain but independent of the canonical sialic acid–binding receptors SIGLEC-1, SIGLEC-7, and SIGLEC-9.
Inactivation of CD43 function restored the ability of macrophages to phagocytize AML. ScienceMission sciencenewshighlights.
Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding regulatory region caused XX mice, which would normally develop as females, to develop instead as males with testis and male genitalia.
The finding is especially striking because the mutation was not made in a gene itself, but in a distant stretch of DNA that helps control a key developmental gene. The study highlights the major role of the non-coding genome —the 98% of DNA that does not make proteins but helps regulate when and how genes are turned on and off.
“This is a remarkable finding because such a tiny change—just one DNA letter out of approximately 2.8 billion—was enough to produce a dramatic developmental outcome,” said Dr. Nitzan Gonen, from the Goodman Faculty of Life Sciences and Institute of Nanotechnology and Advanced Materials at Bar-Ilan University. “It shows that non-coding DNA can have a profound effect on development and disease.”
