The installation converts a cell suspension into droplets and vitrifies it with a flow rate of 100 ml per hour. On July 27, a group from the University of Minnesota released a preprint on cryo-aerosolization: a vibrating nozzle breaks the cell suspension into microdroplets, and a jet of liquid nitrogen freezes them. After thawing, about 90% of human fibroblasts and induced pluripotent stem cel…

Researchers tracked the origin of immune cells in the brains of 20 elderly donors in a Nature article on July 30. They found descendants of bone marrow cells, similar to microglia, in all samples. Microglia clears cellular debris and responds to damage. In mouse experiments, it colonizes the brain before birth and then multiplies locally.
The team of Julia Belk checked if this is also the case i…

The authors of KinoPlex published a map of sites in human proteins where kinases can attach a phosphate on July 29. The researchers connected predicted AlphaFold structures of nearly 20,000 proteins with motifs - short sequence segments that kinases recognize. This map selects positions where a suitable motif matches the available arrangement in the protein's three-dimensional form.

The development by KAIST creates a fully two-way interface between the brain and a robotized exoskeleton. Unlike ordinary BCIs that can only read brain signals and convert them into commands, this development does two things - it receives signals from the brain and sends back sensory information from the robot. This transforms the exoskeleton into not just "external legs", but an extension of t…

A new method measures human muscle strength without implants, using ultra-wideband radar attached to the skin. This is crucial for exoskeletons, robotic prosthetics, and rehabilitation, as these systems must accurately know the force a person is trying to apply. Previously, precise measurements required implanting sensors directly into muscle tissue, making widespread use impossible.

The study, published on July 30, tracked how age alters chemical marks on cysteine, an amino acid found in many proteins. In mice, this shift affected the function of synapsin-1 and G3BP2, and the H₂S donor accelerated the clearance of stress granules in cells. Proteins within cells constantly assemble into small, temporary clusters and then disassemble.
This reversible assembly of p…

Aleksey Turchin proposed limiting AI to help fight aging. He suggests setting a boundary for AI capabilities so that technologies can assist in combating aging while keeping humans in control. Turchin's personal benchmark is an intelligence quotient of around IQ 200; a level of 300, in his opinion, would accelerate the development of nanotechnology.
In discussions about AI safety, the usual debate i…

Biomni and TusoAI have developed an open predictor of cell response to gene knockout. On July 30, Phylo presented the Biomni × TusoAI collaboration for automatic development of biological models. According to the company, the system tested around 500 variants and developed TusoPerturb, an open method for predicting changes in gene activity after CRISPR knockout of another gene.

The PROTEXI vaccine directed memory of COVID-19 against tumors in humanized mouse experiments. On July 27, a study on the dendritic cell vaccine PROTEXI was published in Nature Communications. In experiments on melanoma and breast cancer in mice, researchers pre-established CD4 memory to a model protein fragment and used it against the tumor. In a separate experiment on humanized mice with Spike pep…

Алика Паркс proposed an experiment to check if the mutant p53 unfolds faster than the normal one under weak stretching. On July 29, independent researcher Алика Паркс published a calculation and code for such an experiment. She suggests applying a constant weak force to a single molecule of mutant p53 and measuring how quickly the protein loses its folded form.

Anthropic published the results of Claude Mythos Preview's work on two cryptographic tasks on July 28. The model helped recover the HAWK-256 key and accelerate an attack on a seven-round version of AES-128. Digital signatures confirm who signed a message or owns a digital certificate. HAWK was a NIST candidate for post-quantum signatures, with its security based on a lattice problem.

Pure State Labs' Tayler Vitale has proposed measuring spin in quantum chemical calculations. On July 20, Vitale released an open audit of quantum chemical calculations of iron-sulfur clusters, checking the spin states obtained by the SQD method. Quantum chemistry seeks the electronic state of a molecule and compares the found options by energy.

View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999.
