New technique efficiently offers insight into gene regulation      (via sciencedaily.com)     Original source 

Researchers have developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other.

Scientists use A.I.-generated images to map visual functions in the brain      (via sciencedaily.com)     Original source 

Researchers have demonstrated the use of AI-selected natural images and AI-generated synthetic images as neuroscientific tools for probing the visual processing areas of the brain. The goal is to apply a data-driven approach to understand how vision is organized while potentially removing biases that may arise when looking at responses to a more limited set of researcher-selected images.

Researchers show an old law still holds for quirky quantum materials      (via sciencedaily.com)     Original source 

Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat. And in 1853, two scientists showed that those two admirable properties of metals were somehow related: At any given temperature, the ratio of electronic conductivity to thermal conductivity was roughly the same in any metal they tested. This so-called Wiedemann-Franz law has held ever since -- except in quantum materials. Now, a theoretical argument put forth by physicists suggests that the law should, in fact, approximately hold for one type of quantum material, the cuprate superconductors.

Clever dosage control mechanism of biallelic genes      (via sciencedaily.com)     Original source 

Researchers have uncovered a mechanism that safeguards the biallelic expression of haploinsufficient genes, shedding light on the importance of having two copies of each chromosome. A study identified the epigenetic regulator MSL2 an 'anti-monoallelic' factor that maintains biallelic gene dosage. This discovery not only reveals a communication system between parental alleles but also points to potential therapeutic strategies for diseases associated with haploinsufficient genes.

Tracing the evolution of the 'little brain'      (via sciencedaily.com)     Original source 

The evolution of higher cognitive functions in humans has so far mostly been linked to the expansion of the neocortex. Researchers are increasingly realizing, however, that the 'little brain' or cerebellum also expanded during evolution and probably contributes to the capacities unique to humans. A research team has now generated comprehensive genetic maps of the development of cells in the cerebella of human, mouse and opossum. Comparisons of these maps reveal both ancestral and species-specific cellular and molecular characteristics of cerebellum development.

The secret life of an electromagnon      (via sciencedaily.com)     Original source 

Scientists have revealed how lattice vibrations and spins talk to each other in a hybrid excitation known as an electromagnon. To achieve this, they used a unique combination of experiments on an X-ray free electron laser. Understanding this fundamental process at the atomic level opens the door to ultrafast control of magnetism with light.

Genomic tug of war could boost cancer therapy      (via sciencedaily.com)     Original source 

Researchers have discovered a 'genomic tug of war' in animal studies that could influence how well certain patients -- or certain cancers -- respond to decitabine, a drug used to treat myelodysplastic syndromes that is plagued by drug resistance issues. For the first time, researchers show that decitabine causes coding and non-coding regions of DNA to engage in a tug of war for a gene activator, called H2A.Z. Typically, deticabine draws this gene activator away from coding DNA, causing gene expression to grind to a halt and cells to die. However, many types of cancer have very high levels of H2A.Z, which may help them overcome this decitabine-induced tug of war, allowing the cancer to grow.

How cell identity is preserved when cells divide      (via sciencedaily.com)     Original source 

A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation.  Within each cell's nucleus, researchers suggest, the 3D folding patterns of its genome determines which parts of the genome will be marked by these chemical modifications.
