Geoscientists at Sandia National Laboratories used 3D-printed rocks and an advanced, large-scale computer model of past earthquakes to understand and prevent earthquakes triggered by energy exploration.

Injecting water underground after unconventional oil and gas extraction, commonly known as fracking, geothermal energy stimulation and carbon dioxide sequestration all can trigger earthquakes. Of course, energy companies do their due diligence to check for faults—breaks in the earth’s upper crust that are prone to earthquakes—but sometimes earthquakes, even swarms of earthquakes, strike unexpectedly.

Spurred on by quantum experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.

Summary: Study identified 300 “hub genes” that appear to control separate gene networks in brain tissue samples. The SAMD3 gene appears to be a master regulator to control the activity of many of the gene hubs and the genes the hubs control.

UT Southwestern scientists have identified key genes involved in brain waves that are pivotal for encoding memories. The findings, published online this week in Nature Neuroscience, could eventually be used to develop novel therapies for people with memory loss disorders such as Alzheimer’s disease and other forms of dementia.

Researchers have developed a new data transfer system that is 20 times faster than USB 3.0.

This combines high-frequency silicon chips with a polymer cable as thin as a strand of hair. The system could boost energy efficiency in data centres and lighten the loads of electronics-rich spacecraft. Researchers presented their breakthrough at the recent IEEE International Solid-State Circuits Conference, held virtually.

“There’s an explosion in the amount of information being shared between computer chips – cloud computing, the Internet, big data. And a lot of this happens over conventional copper wire,” says Jack Holloway, who led the research. Holloway completed his PhD in MIT’s Department of Electrical Engineering and Computer Science last year and currently works for Raytheon.

It was the 6th launch and landing for this Falcon 9 first stage.

A SpaceX Falcon 9 rocket launched a new batch of 60 Starlink internet satellites to orbit early this morning (March 11) and nailed its landing on a floating platform at sea.

“This is a fascinating study of gut microbiome in older adulthood,” wrote Barbara Bendlin from the University of Wisconsin, Madison. “While the investigators did not look at brain health or cognitive outcomes, it’s interesting to see that they found that healthy aging was accompanied by gut microbiomes that became increasingly more unique to each person starting in middle age. This type of divergence is also observed in brain aging.” (Full comment below.)

Past studies have shown that the gut microbiome undergoes rapid changes in the first three years of life, followed by a longer period of relative stability, then more change once again in later years (Yatsunenko et al., 2012; O’Toole and Jeffery, 2015). Research has also found that centenarians have fewer of the gut microbes commonly seen in younger, healthy people. Instead, they live with an increasingly rarefied microbiota (Kim et al., 2019). This suggests that gut microbiomes become increasingly personalized as people get older, but little is known about how these gut profiles affect the aging process or longevity.

To find out, first author Tomasz Wilmanski and colleagues analyzed gut microbiomes, personal traits, and clinical data from more than 9000 people 18 to 101 years old. They came from three independent cohorts. One was a group of 3653 people aged 18 to 87 who had signed up with Arivale, a now-defunct scientific wellness company co-founded by systems biology pioneer Leroy Hood and Price. Arivale provided personalized wellness coaching by collecting and analyzing data on participants’ genomes and other systems, including their gut microbiomes. Hood founded the Institute for Systems Biology.

All of us, even physicists, often process information without really knowing what we’re doing.

Russia and China have unveiled plans for a joint lunar space station, with the Russian space agency Roscosmos saying it has signed an agreement with China’s National Space Administration (CNSA) to develop a “complex of experimental research facilities created on the surface and/or in the orbit of the moon”.

The CNSA, for its part, said the project was “open to all interested countries and international partners” in what experts said would be China’s biggest international space cooperation project to date.
