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.

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.

Key protein in blood vessel's growth identified      (via sciencedaily.com)     Original source 

New research identifies the class II PI3K-C2b protein, a member of the PI3 family of kinases, as one of the key regulators of blood vessels growth in humans and other mammals. Mutations in these family of proteins may lead to vascular malformations and the precise understanding of the whole process is instrumental in opening the door to new therapeutic approaches in the future.

Releasing brakes on biocatalysis      (via sciencedaily.com)     Original source 

Enzymes from microorganisms can produce hydrogen (H2) under certain conditions, which makes them potential biocatalysts for biobased H2 technologies. In order to make this hydrogen production efficient, researchers are trying to identify and eliminate possible limiting factors. These include formaldehyde, which occurs naturally as a metabolic product in cells and inhibits the particularly efficient [FeFe] hydrogenase.

How do you make a robot smarter? Program it to know what it doesn't know      (via sciencedaily.com)     Original source 

Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates a much higher degree of uncertainty -- and triggers the robot to ask for clarification.
