A Colorado prison is now the site of the state’s largest confirmed COVID-19 outbreak as mass testing confirms that 238 inmates at Sterling Correctional Facility have the virus.

The number of positive cases at the facility spiked as more results from the 472 tests administered last week became available. Of those tested, half were positive. Sixteen tests were inconclusive, 216 were negative and two were still pending Tuesday afternoon, Colorado Department of Corrections spokeswoman Annie Skinner said in an email.

Four of the sick inmates were in the hospital Tuesday afternoon, Skinner said.

Researchers from MIT have designed artificial muscles filled with water and powered by lithium batteries.

Researchers at the National Astronomical Observatory of Japan (NAOJ) have used the infrastructure of the former TAMA300 gravitational wave detector in Mitaka, Tokyo, to demonstrate a new technique to reduce quantum noise in detectors. This new technique will increase the sensitivity of the detectors comprising a collaborative worldwide gravitational wave network, allowing them to observe fainter waves.

When it began observations in 2000, TAMA300 was one of the world’s first large-scale interferometric gravitational wave detectors. At that time TAMA300 had the highest sensitivity in the world, setting an upper limit on the strength of gravitational wave signals; but the first detection of actual gravitational waves was made 15 years later in 2015 by LIGO. Since then, detector technology has improved to the point that modern detectors are observing several signals per month. The scientific results obtained from these observations are already impressive, and many more are expected in the coming decades. TAMA300 is no longer participating in observations, but is still used as a testbed for new technologies to improve other detectors.

The sensitivity of current and future gravitational wave detectors is limited at almost all the frequencies by quantum noise caused by the effects of vacuum fluctuations of the electromagnetic fields. But even this inherent quantum noise can be sidestepped. It is possible to manipulate the vacuum fluctuations to redistribute the quantum uncertainties, decreasing one type of noise at the expense of increasing a different, less obstructive type of noise. This technique, known as vacuum squeezing, has already been implemented in gravitational wave detectors, greatly increasing their sensitivity to higher frequency gravitational waves. But the optomechanical interaction between the electromagnetic field and the mirrors of the detector causes the effect of vacuum squeezing to change depending on the frequency. So at low frequencies, vacuum squeezing increases the wrong type of noise, actually degrading sensitivity.

Idaho-based beef purveyor Snake River Farms is donating 35,000 10-ounce steaks to Bay Area food banks, with a total value of $2 million, the San Francisco Chronicle reports. It’s part of a larger initiative the company announced last week, which will send $8 million worth of its American wagyu to cities around the country to feed hospital workers, laid-off restaurant staff and other communities affected by the Covid-19 crisis. Snake River is relying on regional distribution partners in Los Angeles, Seattle, New York and San Francisco to help them get their donation to nonprofits.

With restaurants shut down, Snake River Farms is giving its premium beef a good home.

Like all communities, space colonies need to be socially stable. What do succeeded and failed Utopia’s on Earth teach us?

Most utopian communities are, like most start-ups, short-lived. What makes the difference between failure and success?

Let us not forget to finally get rid of this old killer.
