Engineers put tens of thousands of artificial brain synapses on a single chip

Maria J. Danford

The layout could advance the development of tiny, portable AI equipment.

MIT engineers have designed a “brain-on-a-chip,” more compact than a piece of confetti, that is manufactured from tens of hundreds of synthetic mind synapses regarded as memristors — silicon-dependent parts that mimic the details-transmitting synapses in the human mind.

The researchers borrowed from principles of metallurgy to fabricate each memristor from alloys of silver and copper, alongside with silicon. When they ran the chip via quite a few visual jobs, the chip was able to “remember” stored photos and reproduce them lots of times about, in versions that were

Spiky neural networks | Technology Org

Engineering can choose cues from nature, but researchers can also use technology to improved fully grasp some natural phenomena. In a the latest experiment, researchers aimed to demonstrate the adaptable conduct of organic neural networks through the use of synthetic types.

They uncovered, counterintuitively, that adding some noisy spikes into the in any other case smooth manage sign of a robot’s neural network can in fact increase its stability of motion. This kind of conduct mimics what is seen in organic neurons. This exploration could be in particular helpful in improving how robots and other programs can adapt to unfamiliar

Protecting the solar energy grid from cyberattacks

A potential driven by renewables promises sustainable vitality and a cleaner environment – but that doesn’t mean it is with out threats. Incorporating supplemental points of era these as solar farms can inadvertently introduce comfortable accessibility points for cyber hackers trying to get to exploit weaknesses in the nation’s energy grid.

That is why Jin Ye and WenZhan Song, professors in the University of Georgia College of Engineering, are functioning with a consortium of partners from the public and personal sectors to shore up the country’s energy grid’s defenses.

The COVID-19 pandemic is impacting the way we do the job, socialize, and most importantly how we treatment for those who are most susceptible. Micron would like to carry alongside one another the neighborhood of builders, makers, tinkerers, and researchers to make a expense-productive and protected robotic resolution to improve area sanitation through the use of UV mild to deactivate pathogens.

Twitter takes down Beijing-backed influence operation – Software

Maria J. Danford

Twitter on Thursday claimed it eradicated extra than 170,000 accounts tied to a Beijing-backed impact procedure that deceptively unfold messages favourable to the Chinese government, such as about the coronavirus.

The corporation suspended a main community of 23,750 remarkably energetic accounts, as properly as a greater community of about 150,000 “amplifier” accounts employed to raise the main accounts’ articles.

Twitter, along with scientists who analysed the accounts, claimed the community was mostly an echo chamber of bogus accounts with out substantially more traction.

The corporation also eradicated two scaled-down condition-backed functions which it attributed to Russia and Turkey, the two
