Google announced today it will be applying AI advancements, including a new technology called Multitask Unified Model (MUM) to improve Google Search. At the company’s Search On event, the company demonstrated new features, including those that leverage MUM, to better connect web searchers to the content they’re looking for, while also making web search feel more natural and intuitive.

One of the features being launched is called “Things to know,” which will focus on making it easier for people to understand new topics they’re searching for. This feature understands how people typically explore various topics and then shows web searchers the aspects of the topic people are most likely to look at first.

How close is nuclear fusion to break-even? If you trust the headlines we’re getting close and the international project ITER is going to be the first to produce energy from fusion power. But not so fast. Scientists have, accidentally or deliberately, come to use a very misleading quantity to measure their progress. Unfortunately we’re much farther away from generating fusion power than the headlines suggest.

A comet so massive that it was initially misidentified as a dwarf planet is on its way in from the outer Solar System.

There’s no need to be concerned; C/2014 UN271 (Bernardinelli-Bernstein), as the comet is known, will pass just outside Saturn’s orbit. However, its large size and close proximity will provide a once-in-a-lifetime opportunity to study a pristine object from the Oort Cloud and learn more about the formation of the Solar System.

“We have the privilege of having discovered perhaps the largest comet ever seen – or at least larger than any well-studied one – and caught it early enough for people to watch it evolve as it approaches and warms up,” co-discoverer and astronomer Gary Bernstein from the University of Pennsylvania said earlier this year.

The future of package delivery, taxis, and even takeout in cities may be in the air—above the gridlocked streets. But before a pizza-delivery drone can land safely on your doorstep, the operators of these urban aircraft will need extremely high-resolution forecasts that can predict how weather and buildings interact to create turbulence and the resulting impacts on drones and other small aerial vehicles.

While scientists have been able to run simulations that capture the bewilderingly complex flow of air around buildings in the urban landscape, this process can take days or even weeks on a supercomputing system—a timeline far too slow (and a task far too computationally expensive) to be useful to daily weather forecasters.

The gene-regulatory mechanisms driving prefrontal cortex expansion.

SAN FRANCISCO – Launchspace Technologies Corp., a company developing technology to capture orbital debris, is the latest space startup to seek funding on an equity crowdfunding platform.

As of Oct. 2 LaunchSpace had raised $58,351 at a valuation of nearly $49 million on Netcapital.

On the Netcapital site, LaunchSpace is heralding its recent grant from the nonprofit Center for the Advancement of Science in Space (CASIS) to support its plan to test technology for collecting orbital debris on the International Space Station.

DeversiFi’s faulty bill shows crypto, where “code is law”, is equally vulnerable to costly slip-ups that have no formal resolution mechanism.

“Right now, most of the users of DeFi are true believers in the technology and its potential, and so confidence may persist regardless of these events,” said Hilary Allen, professor of law at the American University Washington College of Law.

“But if DeFi is more broadly adopted by people less committed to the technology, confidence will become more vulnerable — and the potential for panics that can come with damaged confidence should give us pause,” she added.

Scientists in Montreal discover a new enzymatic complex that can stop cells from aging, opening the way to possible new cancer therapies.

Researchers at Université de Montréal and McGill University have discovered a new multi-enzyme complex that reprograms metabolism and overcomes “cellular senescence,” when aging cells stop dividing.

In their study published on September 16 2021, in Molecular Cell, the researchers show that an enzyme complex named HTC (hydride transfer complex) can inhibit cells from aging.
