Getting computers to “think” like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. The human brain is a master of applying previously learned knowledge to new situations and constantly refining what’s been learned. This ability to be adaptive has been hard to replicate in machines.
Now, Salk researchers have used a computational model of brain activity to simulate this process more accurately than ever before. The new model mimics how the brain’s prefrontal cortex uses a phenomenon known as “gating” to control the flow of information between different areas of neurons. It not only sheds light on the human brain, but could also inform the design of new artificial intelligence programs.
Big read: Is there such thing as a humane eviction?

The tenants in the third-floor apartment had 30 minutes to leave. Deputies from the Hampden County Sheriff s Department in black uniforms, with bulletproof vests and gold star badges had climbed the back stairs with an eviction notice.
The tenants 22 and 23, in matching Tommy Hilfiger sweatshirts and Crocs were exhausted and dazed. They had stuffed some of their possessions into trash bags and suitcases, but much of what they owned would be left behind, in mounds on the floor. I m sorry it s so messy, said one of the women. In those last moments before becoming homeless, she stood at the sink, carefully washing out the baby bottles they used to feed their puppy.

More than half of Hudson River tidal marshes were created accidentally by humans
AMHERST, Mass. - In a new study of tidal marsh resilience to sea level rise, geologist and first author Brian Yellen at the University of Massachusetts Amherst and colleagues observed that Hudson River Estuary marshes are growing upward at a rate two to three times faster than sea level rise, suggesting that they should be resilient to accelerated sea level rise in the future, he says.
Writing in
Earth Surface Processes and Landforms, Yellen and colleagues documented that more than half of Hudson River tidal marshes formed since 1850. That year, the channel was straightened and a riverside railroad, berms, jetties and human-made islands of dredged soil were built. This all trapped sediment and created backwaters that often - but not always - turned into marshes, an unintended result of early industrial development, they state.
