Museums are safest indoor activity, study finds

For people fatigued with quarantine amid the COVID-19 pandemic, a new study from Germany recommends what to do after getting out of the house.

Don’t go out to eat or get a haircut, don’t go shopping for food or go to the gym —  go to a museum.

According to the Berlin Institute of Technology (TU Berlin) in Germany, the risk of COVID-19 infection via aerosol particles is far lower in museums than in supermarkets, restaurants, offices and on public transportation.

Variables considered were the quality of the airflow, the type of activity carried out in the space, and the dose of aerosol particles inhaled by people in a room.

“What is clear from the study is that it is above all the situations in which we like to be that are unfavorable,” said Martin Kriegel, who helped lead the study. “Situations in which many people come together in a confined space: there you can not ventilate sufficiently, it will always be an unfavorable situation.”

Outdoor activities all increased last year in the face of canceled indoor events and cautions about the dangers of catching the virus while around other people inside.

The study said food shopping, dining indoors or exercising in a gym are at least twice as risky as visiting a museum to view art.

Museums, however, haven’t been considered essential to the populace.

Celeste DeWald, the executive director of the California Association of Museums, told the New York Times earlier this month: “It’s frustrating to see crowded shopping malls and retail spaces and airports, yet museums are completely closed and many have not been able to reopen at all for the last 10 months. […] There is a unique impact on museums.”

Critics think museum closure is a political matter.

In a column for the Los Angeles Times, art critic Carolina A. Miranda called California Gov. Gavin Newsom’s policies “absurd.” Museums in the Golden State remain closed to visitors.

“The wildly uneven criteria speak more to the powerful, well-funded lobbies helping shape public health policy than to anything resembling science or even common sense,” Miranda wrote. “At a moment in which it is possible to get a tattoo or paw the goods at Chanel in Beverly Hills, it should be possible to visit a museum. Period.”

Bill Gates said to be growing potatoes for McDonald’s fries

Bill Gates said to be growing potatoes for McDonald's fries

Next time you savor a McDonald’s french fry, remember to thank Bill Gates for the tasty spud.

As reported in The Post, the soon-to-be single computer magnate happens to own more farmland than anyone else in the United States. Known for loving fast food — although his burger of choice comes from the Washington-based chainlet Burgermaster — Gates, according to NBC News, grows potatoes for McDonald’s in fields so vast they can be scoped from outer space.

Although Gates has focused his energies on saving our climate, he has made clear that the tater patches are strictly money-making operations.

“My investment group chose to do this,” stated Farmer Bill during an AMA on Reddit. “It is not connected to climate.”

Considering that Gates is said to own 269,000 acres of fertile land in 18 states, it’s easy to imagine him keeping track of it all on some souped-up series of spreadsheets. If so, gangs of divorce lawyers — including some who worked on the Jeff Bezos bust-up — have surely been scrutinizing the potato haul. Gates, the fourth-richest person in the world, married his impending ex, Melinda, without a prenuptial agreement, so they will be splitting property via a so-called “separation contract.”

No word on whether or not she will soon reign as McDonald’s potato queen.

Honeybee worker can produce millions of identical clones, study shows

Honeybee worker can produce millions of identical clones, study shows

A South African subspecies of the honeybee is reportedly able to produce millions of clones of itself. 

According to new research published in the journal Current Biology and Proceedings of the Royal Society B, one such insect – known as the Cape honeybee or Apis mellifera capensis– has managed to do so many times over the past 30 years. 

It’s a process called thelytokous parthenogenesis, which a group of international scientists said is akin to the “virgin birth of a female.” 

While asexual reproduction is fairly common, genetically identical offspring is not. 

The exchange of genetic material between different organisms, or “recombination,” normally leads to the production of offspring with combinations of different traits.

If there even is only one parent, New Scientist noted, offspring born from thelytokous parthenogenesis will still be born with a slightly different genetic makeup.

And yet, the worker Cape honeybee has reportedly found a way to reduce recombination and remain genetically healthy, whereas asexual reproduction has been lethal in honeybees before, resulting in inbred larvae that don’t survive. 

“For workers, it is important to reduce the frequency of recombination so as to not produce offspring that are homozygous.”

In order to learn more, the paper’s authors “experimentally manipulated” Cape workers and Cape queens to reproduce thelytokously.

“The two female castes of the Cape honeybee, Apis mellifera capensis, differ in their mode of reproduction. While workers always reproduce thelytokously, queens always mate and reproduce sexually,” the researchers explained in the paper’s abstract.

Performing fieldwork at South Africa’s Plant Protection Research Institute in Stellenbosch, the team instrumentally inseminated a queen with the semen of a single male and then introduced a brood comb holding several hundred eggs laid by the queen into a colony to be reared. 

Queens were made to reproduce asexually using what researchers said amounted to a “chastity belt.”

“When the queens were 5 days post eclosion we constrained them in an artificial insemination apparatus [37] without narcosis. We then glued a 5 mm piece of surgical tape (Micropore, 3M, Minnesota) over the sting chamber using nail varnish,” the paper explained. 

The researchers monitored the queens, confirming the chastity belts were intact after each flight around the colony and, eventually, compared asexually reproduced larvae of the queen to those of the workers.

“We monitored the queens closely for the next two weeks, to determine if and when oviposition had commenced. We collected larvae as soon as they appeared into ethanol,” the researchers wrote.

“Not all queens flew, not all returned from mating flights, and not all laid. In the end, we were able to harvest one queen and 25 of her larval progeny into ethanol.”

The group also genotyped four workers and 63 of their larvae.

Ultimately, the authors found that the queen showed levels of genetic recombination 100 times more than seen in the cloned offspring of the worker bees.

“Using a combination of microsatellite genotyping and whole-genome sequencing we find that a reduction in recombination is confined to workers only,” the abstract concluded.

Russia's navy kicks off large-scale drills in Pacific ocean

Large-scale drills of Russia’s Pacific Fleet began in the central part of the Pacific Ocean, the Russian Ministry of Defense reported on Thursday, June 10.

According to the ministry, 20 warships, submarines and support vessels are taking part in the exercises. In particular the missile cruiser “Varyag”, the large anti-submarine ship “Admiral Panteleev”, the frigate “Marshal Shaposhnikov” as well as other military and support vessels.

In addition, about 20 aircraft are involved in the exercise, including Tu-142mz long-range anti-submarine aircraft and MiG-31BM high-altitude fighter-interceptors.
