On-chip training of machine learning algorithms is challenging for photonic devices. Here, the authors construct nonlinear mapping functions in silicon photonic circuits, and experimentally demonstrate on-chip bacterial foraging training for projection-based classification.
It’s effectively a new data set that will fuel the second wave of discoveries about Mars’ surface composition.
But while it was doing that work, it was also gathering lower-resolution mapping strips, about 83,000 of them. Now that CRISM is no longer active, the team is building their map from those strips.
Processing this much data into one cohesive map is a complicated task requiring powerful computing resources. It takes time to optimize the maps and account for environmental conditions and discrepancies between the different images.

We know the brain changes after traumatic injury, and now we have maps from mice showing what that change looks like.
A team of scientists has traced connections between nerve cells throughout the entire brain of mice, showing that distant parts of the brain become disconnected after a head injury.
The stunning visualizations of brain-wide connectivity could help scientists understand how a traumatic brain injury, or TBI, alters cross-talk between different cells and brain regions, first in mice and then in humans.

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
“We looked at the current knowledge of the configuration of plate boundary zones and the past construction of the continental crust,” said Dr. Derrick Hasterok, Lecturer, Department of Earth Sciences, University of Adelaide who led the team that produced the new models.

Scientists have created the first reference charts for the human brain, mapping its growth from infancy to 100 years old. Now, they have to grapple with difficult ethical questions about how they should — and perhaps shouldn’t — be used.
The reference charts are visualizations created from aggregating analyses of over 120,000 brain scans to show ranges in brain size, or gray matter volume, for each age. They also track the human brain’s rapid expansion early in life and its gradual shrinking over time. The researchers primarily developed the charts to provide a standardized measurement that other neuroscientists could use for brain imaging research, with the hope that maybe one day it could lead to a tool used in clinics.
“It’s an absolutely spectacular advancement in neuroscience and neuroimaging,” said Judy Illes, professor of neurology and neuroethics at the University of British Columbia.
Shield AI, an artificial intelligence company focusing on drones and other autonomous aircraft, is on a mission to build “the world’s best AI pilot.” To that end, the San Diego startup has raised $90 million in equity and $75 million in debt as part of a Series E fundraising round. The funding values Shield AI at $2.3 billion.
Hivemind employs state-of-the-art algorithms for planning, mapping, and state-estimation to enable drones to execute dynamic flight maneuvers. On aircraft, Hivemind enables full autonomy and is designed to run fully on the edge, disconnected from the cloud, in high-threat GPS and communication-degraded environments.
Scientists are attempting to map the wiring of the nearly 100 billion neurons in the human brain. Are we close to uncovering the mysteries of the mind or are we only at the beginning of a new frontier?

Google’s AI division is creating digital versions of – normally hand-drawn – maps of electricity cables, in a move that could benefit the global utility industry.
The firm’s DeepMind engineers have partnered with UK Power Networks which delivers electricity across London, the East and South East, to create digital versions of maps covering more than 180,000km of electricity cables.
The work involves new image recognition software scanning thousands of maps – some of which date back decades – and automatically remastering them into a digital format for future use.
