Our brains are among the most complex objects in the known universe. Deciphering how they work could bring tremendous benefits, from finding ways to treat brain diseases and neurological disorders to inspiring new forms of machine intelligence.

But a critical starting point is coming up with a parts list. While everyone knows that brains are primarily made up of neurons, there are a dazzling array of different types of these cells. That’s not to mention the various kinds of glial cells that make up the connective tissue of the brain and play a crucial supporting role.

That’s why the National Institutes of Health’s BRAIN Initiative has just announced $500 million in funding over five years for an effort to characterize and map neuronal and other types of cells across the entire human brain. The project will be spearheaded by the Allen Institute in Seattle, but involves collaborations across 17 other institutions in the US, Europe, and Japan.

BGI Genomics, in collaboration with Southwest University, the State Key Laboratory of Silkworm Genome Biology, and other partners, has constructed a high-resolution pangenome dataset representing almost the entire genomic content in a silkworm.

This research paper, providing genetic insights into artificial selection (domestication and breeding) and ecological adaptation, was published on September 24 in Nature Communications.

Previously, due to the scarcity of wild silkworms and technical limitations of former studies, many trait-associated sites were missing. This is the first research ever to digitize silkworm gene pool and create a “digital silkworm”, greatly facilitating functional genomic research, promoting precise breeding, and thus enabling additional silk use cases.

A collaborative effort has succeeded in upgrading solar-powered microbots – each of which now has their own built-in, miniature computer – allowing them to walk autonomously and without being externally controlled.

Cornell researchers and others had previously developed microscopic machines able to crawl, swim, walk, and fold themselves up. However, these always had “strings” attached; to generate motion, they needed wires to provide electrical current, or laser beams focused directly onto specific parts of robots.

“Before, we literally had to manipulate these ‘strings’ in order to get any kind of response from the robot,” explained Itai Cohen, Professor at Cornell’s Department of Physics. “But now that we have these brains on board, it’s like taking the strings off the marionette. It’s like when Pinocchio gains consciousness.”

A new method allows MIT’s Mini Cheetah to learn how to run fast and adapt to walking on challenging terrain. This learning-based method outperforms previous human-designed methods and allowed the Mini Cheetah to set a record for speed.

The work was supported by DARPA Machine Common Sense Program, Naver Labs, MIT Biomimetic Robotics Lab, and the NSF AI Institute of AI and Fundamental Interactions. The research was conducted at the Improbable AI Lab.

Post-mortem brains of SuperAgers reveal significantly larger neurons in memory region. SuperAger neurons are even larger than those in individuals 20 to 30 years younger These neurons do not have tau tangles that are a hallmark of Alzheimer’s Larger neurons in the brain’s memory region.

The streets in this meticulously planned neighborhood were designed to flood so houses don’t. Native landscaping along roads helps control storm water. Power and internet lines are buried to avoid wind damage. This is all in addition to being built to Florida’s robust building codes.

Some residents, like Grande, installed more solar panels on their roofs and added battery systems as an extra layer of protection from power outages. Many drive electric vehicles, taking full advantage of solar energy in the Sunshine State.

Climate resiliency was built into the fabric of the town with stronger storms in mind.

Let your cargo follow you while you travel comfortably with the gita plus cargo carrying robot. Double the size of the gita mini robot, this robot comes with pedestrian etiquette. In fact, this robot is perfect for families who need larger cargo space, business owners, or anyone who wants an extra set of hands. The sleek design looks unique and one of a kind. In fact, this robot also has a built-in speaker. It allows you to use the mygita app to stream music from your smartphone. With the help of cameras and radar technology, this robot can see its surroundings and pair with its user. In fact, it takes just one tap for the gita plus to pair to you. It stands and self-balances, braking automatically when needed and adjusting its speed to keep pace along the way.
