Summary: Hippocampal adult-born neurons are responsible for memory consolidation during REM sleep.

The presence of dreaming during rapid-eye-movement (REM) sleep indicates that memory formation may occur during this sleep stage. But now, researchers from Japan have found that activity in a specific group of neurons is necessary for memory consolidation during REM sleep.
In 1965, Intel co-founder Gordon Moore predicted that the number of transistors that could fit on a computer chip would grow exponentially —- and they did, doubling about every two years. For half a century Moore’s Law has endured: computers have gotten smaller, faster, cheaper and more efficient, enabling the rapid worldwide adoption of PCs, smartphones, high-speed Internet and more.
This miniaturization trend has led to silicon chips today that have almost unimaginably small circuitry. Transistors, the tiny switches that implement computer microprocessors, are so small that 1000 of them laid end-to-end are no wider than a human hair. For a long time, the smaller the transistors were, the faster they could switch.
But today, we’re approaching the limit of how small transistors can get. As a result, over the last decade researchers have been scratching their heads to find other ways to improve performance so that the computer industry can continue to innovate.
The number of startup companies and the amount of investment dollars going into the field of cultivated meat has exceeded—and will likely continue to exceed—annual exponential growth.
As we race to find sustainable ways to feed the world’s insatiable appetite for meat, the field of cultivated meat has exceeded annual exponential growth— more than doubling every year in terms of the number of startup companies and investment dollars. In late 2015, one startup raised a few hundred thousand dollars. In 2020, there are dozens of cultivated meat companies around the world pursuing everything from shrimp and bluefin tuna to steak and kangaroo.
This year, the sector took another significant step forward when cultivated meat first-mover Memphis Meats closed a $161 million Series B funding round from lead investors Softbank, Norwest, and Temasek. This amount is greater than all other publicly disclosed investments in cultivated meat companies combined and brings total investment in the startup to $181 million.
What does an investment like this mean for cultivated meat companies and the field as a whole? Having tracked the sector since its inception, I think there are three key takeaways.
Rapamycin, a drug that has life-extending effects on mice (and possibly dogs and humans), also reverses age-related dental problems in mice. 🦷 Out now in eLife from researchers at The University of Washington School of Dentistry & JAX’s Kaczorowski Lab:
Rapamycin, which has life-extending effects on mice, also reverses age-related dental problems such as periodontitis and regrows bones in the animals.

Pleased to have been the guest on this most recent episode of Javier Ideami’s Beyond podcast. We discuss everything from #spaceexploration to #astrobiology!
In this episode, we travel from Ferdinand Magellan’s voyage to the first mission to Mars with Bruce Dorminey. Bruce is a science journalist and author who primarily covers aerospace, astronomy and astrophysics. He is a regular contributor to Astronomy magazine and since 2012, he has written a regular tech column for Forbes magazine. He is also a correspondent for Renewable Energy World. Writer of “Distant Wanderers: The Search for Planets Beyond the Solar System”, he was a 1998 winner in the Royal Aeronautical Society’s Aerospace Journalist of the Year Awards (AJOYA) as well as a founding team member of the NASA Astrobiology Institute’s Science Communication Focus Group.

The COVID-19 pandemic will have a profound impact on robotics, as more companies look to automation as a way forward. While wide-scale automation had long seemed like an inevitability, the pandemic is set to accelerate the push as corporations look for processes that remove the human element from the equation.
Of course, Locus Robotics hasn’t had too much of an issue raising money previously. The Massachusetts-based startup, which raised $26 million back in April of last year, is adding a $40 million Series D to its funds. That brings the full amount to north of $105 million. This latest round, led by Zebra Technologies, comes as the company looks to expand operations with the launch of a European HQ.
“The new funding allows Locus to accelerate expansion into global markets,” CEO Rick Faulk said in a release, “enabling us to strengthen our support of retail, industrial, healthcare, and 3PL businesses around the world as they navigate through the COVID-19 pandemic, ensuring that they come out stronger on the other side.”
