Crucially, they showed that the synapses were capable of Hebbian learning, the process by which the strength of the connection between two neurons increases or decreases based on activity. This is key to the way information is encoded into the brain, with the strengths of connections between neurons controlling the function of different brain circuits.

In biological neurons this ability to alter the strength of connections—known as plasticity—operates at two distinct timescales. Over shorter timescales, regular firing of the neuron leads to a buildup of ions that temporarily increase the ease with which signals pass across. In the long term though, regular activity can cause new receptors to grow at a synapse, resulting in more durable increases in the strength of the connection.

With the artificial synapses, short-term plasticity operates in much the same way due to a buildup of ions. But boosting the connection strength in the long term relies on using voltage pulses to essentially grow new material out of a soup of chemical precursors at the synapse, which increases its conductivity.

Lab experiments pinpoint extra brain growth orchestrated by a single gene change in modern humans.

A gene that evolved in humans over 3 millions years ago accelerated brain growth — but it came with a serious catch.

Construction data can quickly scale into gigabytes and terabytes of data. The field is complicated because teams use various file formats to design, construct and operate a building or facility. Teams must often load the whole file into proprietary rendering tools before showing off a new design or collaborating on schedules. These files can be even more complex when building out large-scale digital twins of whole cities like Helsinki or Singapore.

Bentley Systems hopes to change that. At a technology demonstration event in London, Bentley showed off a new 3D streaming codec for the infrastructure metaverse called 3DFT. It’s already running on the Epic Unreal Engine, and Bentley plans to support other platforms down the road.

3DFT is not the first format for streaming metaverse data. The GIS industry has been streaming 2D data for years using tiles. And the Open Geospatial Consortium has been working on the 3D Tiles standard to extend streaming into the third dimension.

As everyday technologies get more and more advanced, cyber security must be at the forefront of every customer. Cyber security services have become common and are often used by private companies and the public sector in order to protect themselves from potential cyber attacks.

One of these services goes under the name Darktrace and has recently been acquired by Cybersprint, a Dutch provider of advanced cyber security services and a manufacturer of special tools that use machine learning algorithms to detect cyber vulnerabilities. Based on attack path modeling and graph theory, Darktrace’s platform represents organizational networks as directional, weighted graphs with nodes where multi-line segments meet and edges where they join. In order to estimate the probability that an attacker will be able to successfully move from node A to node B, a weighted graph can be used. Understanding the insights gained will make it easier for Darktrace to simulate future attacks.

At 2022 Tesla AI Day, Elon Musk gave the public its first look at his company’s humanoid robot nicknamed Optimus. He expects the production model to cost less than $20,000.

Today we’ll take a look at Tesla’s AI Day and the real star of the show. But first…

Musk and Twitter are set to go to Delaware Chancery Court in mid-October over the Tesla CEO’s attempt to get out of his $44 billion deal to buy the company.

Tesla has unveiled its Optimus humanoid robot at its AI Day 2022 today and Elon Musk believes Tesla can bring it to market for “less than $20,000”.

As expected, the event started with Tesla unveiling a working prototype of its humanoid robot – a project first announced at Tesla’s AI day in 2021.

There were two prototypes unveiled at the event.
