Google Pay now supports school IDs in campuses across the US

  Google Pay now supports school IDs in campuses across the US Android-using students and faculty members from 15 schools across the US will soon be able to use Google Pay as their campus ID. The tech giant's mobile wallet has been able to handle more than just payment transactions for a while now: last year, it added support for tickets and loyalty cards. Now Transact, a company that provides billing and payment services for students, has launched a feature that allows users to save school IDs to their Google Pay app. Fifteen educational institutions have already signed up to be part of the program, and at least one has already started testing out the use of a mobile wallet as a school ID.

A joint effort between Google and the Janelia Research Campus has just achieved a significant breakthrough in brain mapping . They've published the largest high - resolution map of brain connectivity to date, offering a 3D model of 25,000 fruit fly neurons across a diverse range of cell

Scientists from Google and the Janelia Research Campus in Virginia have published the largest high - resolution map of brain connectivity in any animal, sharing a 3D model that traces 20 million synapses connecting some 25,000 neurons in the brain of a fruit fly. The model is a milestone in the

Scientists from Google and the Janelia Research Campus have published the largest ever high-resolution map of a brain: the hemibrain connectome.

On Wednesday, the "largest synaptic-level connectome ever reconstructed" -- created by scientists at Google and the Janelia Research Campus -- was published for the public to explore. The map of brain connections, the hemibrain connectome, outlines none other than that of a fly.

Despite this insect's small size, this map contains about 25,000 neurons grouped into thousands of cell type categories which span multiple regions of the brain.

It's the largest brain map of this type -- called a connectome -- ever created, for any animal, according to the research project website and a paper describing the work. © Provided by CNET Researchers from Google and Janelia Research Campus made a complex map of the brain of a fruit fly.

To do this, a fly's brain was cut into very fine slices using a hot knife. Each section was then placed under an electron microscope and the resulting images were stitched back together to create a 3D rendering of the brain. During this process, the scientists identified over 4,000 types of neurons.

The data is now available for anyone to download. While the neuron construction of a fly's brain may appear to be an unproportionally large feat for such a small insect, it is the largest high-resolution map to date and paves the way for mapping out the brains of larger animals and eventually humans.
