Pakistan suspends winter ascents after 3 climbers go missing

ISLAMABAD — Pakistani authorities suspended all winter ascents, effective immediately, after three climbers went missing while attempting to scale K2 amid harsh weather in the country’s north, a mountaineering official said Wednesday.

The development comes after Pakistan’s climber Ali Sadpara, Jon Snorri of Iceland and Juan Pablo Mohr of Chile lost contact with base camp on Saturday. Their support team has not received any communications from the 28,250-foot high K2, the world’s second highest peak, sometimes referred to as “killer mountain.”

A search and rescue operation could not resume for the straight second day Wednesday because of bad weather, said Karrar Haidri, head of the Pakistan Alpine Club.

He said about two dozen climbers from various countries, who were trying to scale K2, were heading back to their base camps after the immediate suspension of winter expeditions.

Located in the Karakorum mountain range, K2 is one of the most dangerous climbs — one never accomplished in winter until last month, when a team of 10 Nepalese climbers made history by scaling it.

Bad weather has plagued the search. It was halted on Monday as heavy clouds enveloped most of K2. Since then, no helicopter could fly amid diminishing hope for the survival of missing climbers, Haidri said.

He said authorities were meeting Wednesday to decide how to handle the situation amid continuing bad weather. At K2, winds can blow at more than 200 kph (125 mph) and temperatures can drop to minus 60 degrees Celsius (minus 76 Fahrenheit).

In one of the deadliest mountaineering accidents ever, 11 climbers died in a single day trying to scale K2 in 2008. Sadpara’s son Sajid Ali Sadpara, who had began the climb with his father but was forced to abandon the summit attempt after his equipment failed, has said only a miracle could bring the climbers back alive.

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.
