While the Cumberland sample may contain longer chains of fatty acids, SAM is not designed to detect them. But SAM’s ability to spot these larger molecules suggests it could detect similar chemical signatures of past life on Mars if they’re present, Williams said.

“Curiosity is not a life detection mission,” Freissinet said. “Curiosity is a habitability detection mission to know if all the conditions were right … for life to evolve. Having these results, it’s really at the edge of the capabilities of Curiosity, and it’s even maybe better than what we had expected from this mission.”

Before sending missions to Mars, scientists didn’t think organic molecules would be found on the red planet because of the intensity of radiation Mars has long endured, Glavin said.
Curiosity won’t return to Yellowknife Bay during its mission, but there are still pristine pieces of the Cumberland sample aboard. Next, the team wants to design a new experiment to see what it can detect. If the team can identify similar long-chain molecules, it would mark another step forward that might help researchers determine their origins, Freissinet said.

“That’s the most precious sample we have on board … waiting for us to run the perfect experiment on it,” she said. “It holds secrets, and we need to decipher the secrets.”

Briony Horgan, coinvestigator on the Perseverance rover mission and professor of planetary science at Purdue University in West Lafayette, Indiana, called the detection “a big win for the whole team.” Horgan was not involved the study.
“This detection really confirms our hopes that sediments laid down in ancient watery environments on Mars could preserve a treasure trove of organic molecules that can tell us about everything from prebiotic processes and pathways for the origin of life, to potential biosignatures from ancient organisms,” Horgan said.

Dr. Ben K.D. Pearce, assistant professor in Purdue’s department of Earth, atmospheric, and planetary sciences and leader of the Laboratory for Origins and Astrobiology Research, called the findings “arguably the most exciting organic detection to date on Mars.” Pearce did not participate in the research.

Arctic auroras

For getting around during winter, the Inuit here nowadays prefer snowmobiles, although they still keep their sled dogs. During winter they’ll offer intrepid visitors, wrapped up warm against the deep-freeze temperatures, dog-sledding jaunts. These can last either an hour or be part of expeditions over several days, sometimes with the added experience of learning how to build an igloo. Sisimiut on the west coast and Tasilaq in the southeast are active winter centers for dog sledding.

Winter’s most stellar attraction, though, is northern lights watching. With little urban light pollution, Greenland is a dark canvas for spectacular displays, and aurora borealis-watching vacations are becoming more popular.

Staying outdoors, Greenland is developing a reputation among adventure enthusiasts: from long-distance skiing expeditions and heliskiing on the icecap to hiking the 100-mile-long Arctic Circle Trail from Kangerslussuaq, where firearms need to be carried for warning shots in case of polar bear encounters.

Life is definitely changing here. The climate crisis is eating away at its icecap and Greenland may well end up as a pawn in a game of geopolitical chess. But for now, the bright glare of international attention should shine a favorable light on one of the wildest travel destinations on Earth.

Travel writer Mark Stratton is an Arctic specialist who has traveled to Greenland six times and counting. He’s marveled at the aurora borealis, sailed to Disko Island, dog-sledded with the Inuit, and once got stuck in an icefloe.

Ukrainian President Volodymyr Zelensky’s visit to the White House on Thursday could be his final chance to convince a receptive American president of his country’s war aims.
megaweb4.com
The precise details of the “victory plan” Zelensky plans to present in separate meetings to President Joe Biden and Vice President Kamala Harris are unknown, having been closely held until they are presented to the American leaders.

But according to people briefed on its broad contours, the plan reflects the Ukrainian leader’s urgent appeals for more immediate help countering Russia’s invasion. Zelensky is also poised to push for long-term security guarantees that could withstand changes in American leadership ahead of what is widely expected to be a close presidential election between Harris and former President Donald Trump.

The plan, people familiar with it said, acts as Zelensky’s response to growing war weariness even among his staunchest of western allies. It will make the case that Ukraine can still win — and does not need to cede Russian-seized territory for the fighting to end — if enough assistance is rushed in.

That includes again asking permission to fire Western provided long-range weapons deeper into Russian territory, a line Biden once was loathe to cross but which he’s recently appeared more open to as he has come under growing pressure to relent.

Even if Biden decides to allow the long-range fires, it’s unclear whether the change in policy would be announced publicly.

Biden is usually apt to take his time making decisions about providing Ukraine new capabilities. But with November’s election potentially portending a major change in American approach to the war if Trump were to win, Ukrainian officials — and many American ones — believe there is little time to waste.

Trump has claimed he will be able to “settle” the war upon taking office and has suggested he’ll end US support for Kyiv’s war effort.

“Those cities are gone, they’re gone, and we continue to give billions of dollars to a man who refused to make a deal, Zelensky. There was no deal that he could have made that wouldn’t have been better than the situation you have right now. You have a country that has been obliterated, not possible to be rebuilt,” Trump said during a campaign speech in Mint Hill, North Carolina, on Wednesday.

Comments like those have lent new weight to Thursday’s Oval Office talks, according to American and European officials, who have described an imperative to surge assistance to Ukraine while Biden is still in office.

As part of Zelensky’s visit, the US is expected to announce a major new security package, thought it will likely delay the shipping of the equipment due to inventory shortages, CNN previously reported according to two US officials. On Wednesday, the US announced a package of $375 million.

The president previewed Zelensky’s visit to the White House a day beforehand, declaring on the margins of the United Nations General Assembly his administration was “determined to ensure that Ukraine has what it needs to prevail in fight for survival.”

“Tomorrow, I will announce a series of actions to accelerate support for Ukraine’s military – but we know Ukraine’s future victory is about more than what happens on the battlefield, it’s also about what Ukrainians do make the most of a free and independent future, which so many have sacrificed so much for,” he said.

‘For the public to enjoy’
keplr wallet
The museum’s history starts in 1998, when Sheikh Faisal Bin Qassim Al Thani opened a building to the public on his farm some 20 kilometers (12 miles) north of Qatari capital Doha.

A distant relative of Qatar’s ruling family, founder and chairman of Al Faisal Holdings (one of Qatar’s biggest conglomerates), and a billionaire whose business acumen had him recognized as one of the most influential Arab businessmen in the world, Sheikh Faisal had already amassed a substantial private collection of historically important regional artifacts, plus a few quirky pieces of interest, allowing visitors an intimate look into Qatari life and history.

In an interview with Qatari channel Alrayyan TV in 2018, Sheikh Faisal said that the museum started as a hobby.

“I used to collect items whenever I got the chance,” he said. “As my business grew, so did my collections, and soon I was able to collect more and more items until I decided to put them in the museum for the public to enjoy.”

His private cabinet of curiosities has since evolved into a 130-acre complex. Through the fort-like entrance gate lies an oryx reserve, an impressive riding school and stables, a duck pond and a mosque built with a quirky leaning minaret. There’s now even a five-star Marriott hotel, two cafes and the Zoufa restaurant serving modern Lebanese cuisine.

Of course, there’s also the super-sized museum, with a recently-opened car collection housing everything from vintage Rolls-Royces to wartime Jeeps and colorful Buicks. Outside you’ll find peacocks roaming the grounds, and signs warning drivers to be aware of horses and ostriches.

Visitors to the FBQ museum are free to explore the grounds and can even enter the stables to pat the horses.

A long time in the making
Curiosity landed in Gale Crater on August 6, 2012. More than 12 years later, the rover has driven over 21 miles (34 kilometers) to ascend Mount Sharp, which is within the crater. The feature’s many layers preserve millions of years of geological history on Mars, showing how it shifted from a wet to a dry environment.

Perhaps one of the most valuable samples Curiosity has gathered on its mission to understand whether Mars was ever habitable was collected in May 2013.

The rover drilled the Cumberland sample from an area within a crater called Yellowknife Bay, which resembled an ancient lake bed. The rocks from Yellowknife Bay so intrigued Curiosity’s science team that it had the rover drive in the opposite direction to collect samples from the area before heading to Mount Sharp.
Since collecting the Cumberland sample, Curiosity has used SAM to study it in a variety of ways, revealing that Yellowknife Bay was once the site of an ancient lake where clay minerals formed in water. The mudstone created an environment that could concentrate and preserve organic molecules and trapped them inside the fine grains of the sedimentary rock.

Freissinet helped lead a research team in 2015 that was able to identify organic molecules within the Cumberland sample.

The instrument detected an abundance of sulfur, which can be used to preserve organic molecules; nitrates, which are essential for plant and animal health on Earth; and methane composed of a type of carbon associated with biological processes on Earth.

“There is evidence that liquid water existed in Gale Crater for millions of years and probably much longer, which means there was enough time for life-forming chemistry to happen in these crater-lake environments on Mars,” said study coauthor Daniel Glavin, senior scientist for sample return at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in a statement.

Guatemala has pledged a 40% increase in deportation flights carrying Guatemalans and migrants of other nationalities from the United States, President Bernardo Arevalo announced Wednesday during a press conference with US Secretary of State Marco Rubio.

Guatemala has also agreed to create a task force for border control and protection along the country’s eastern borders. The force, composed of members of the National Police and army, will be tasked with fighting “all forms of transnational crime,” Arevalo said.

Foreign nationals who arrive in Guatemala through deportation flights will be repatriated to their home countries, Arevalo said, adding that the US and Guatemala would continue to have talks on how the process would work and how the US would cooperate.

Arevalo also said that Rubio has voiced his support for developing infrastructure projects in the Central American nation. He added that his government would send a delegation to Washington in the coming weeks to negotiate deals for economic investments in Guatemala – which he said would incentivize Guatemalans to stay in their home country and not migrate to the US.

Arevalo said Guatemala has not had any discussions about receiving criminals from the US as El Salvador’s president has offered. He also insisted his country has not reached a “safe third country” agreement with the United States, which would require migrants who pass through Guatemala to apply for asylum there rather than continuing to the US.

Моя мама, та ещё модница. Каждые выходные, её можно было найти в нашем Торговом Комплексе (ТК). Пропадая там часами и толком ничего не купив, за такое проведённое время, если только так по мелочи, у меня это вызывало недоумение. И тут же напрашивался, естественно закономерный вопрос. Что можно там делать, целый день?
Жесткое порно
Конечно, я много раз навязывался на поход в ТК с мамой, объясняя разные причины, чтобы посетить, это «чудесное» заведение. Но каждый раз слышал, от неё только отказ.

Мама была у меня симпатичной женщиной с приличной грудью третьего размера, да и в меру обладая стройностью тела, выглядела в свои сорок лет, даже очень ничего. Многие мужчины, часто поглядывали в её сторону, на что мама строя им глазки, пыталась флиртовать с ними. Меня же это раздражало. Возможно во мне играла ревность, что не я центр её внимания.
Порно безкоштовно
Но странное поведение мамы, вынуждало меня узнать всё таки истинную причину, её не обычного влечения к шопомании.

Заранее купив новой одежды, чтобы не быть узнаным, и облачившись в эти шмотки, изменив облик, а на глаза нацепив солнцезащитные очки с бейсболкой, я решил проследить за мамой, когда она в очередной раз, пошла за покупками в ТК.
Домашнє порно
Неотступно ступая ей в след, я добрался с ней до ТК. Не распознав меня, хотя я перед мамой часто светился, проверяя свою маскировку, мы вошли во внутрь этого грандиозного здания. По началу она и вправду ходила по бутикам, оглядываясь не редко на мужчин, а с некоторыми даже беседовала, но коротко, перекидываясь всего парой фраз. Я не слышал о чем они говорили, но по виду мужчин, можно сказать, что оппоненты очень были заинтересованы в этом разговоре.

Спустя час, её брожения по лабиринтам этих бутиков, она остановилась в одном из них и выбрав какую-то блузку, двинулась в сторону кабинки. Подойдя к ней, она оглянулась по сторонам и еще раз взглянув на номер над шторкой и убедившись, что именно в эту примерочную ей надо, мама не суетясь зашла туда.

Подумав, что здесь нет ничего необычного, я приметил молодого человека, с которым мама останавливалась и разговаривала. Он бродил по бутику и высматривал вещи, всё время поглядывая на кабинки. Выбрав что-то из одежды, он подошёл именно к той самой примерочной, куда некоторое время назад зашла моя мама. На вид парень был, чуть старше меня и испуганно взирая по сторонам, открыв штору кабинки, прошёл не задерживаясь во внутрь.

Я глазам своим не мог поверить, что это происходит. Разные мысли в голове, стали меня посещать и в основном они были интимного характера. Неужели моя мама, встречается с этим юнцом и в тайне от отца, изменяет ему, таким способом в примерочной кабинке ТК.

Да, да. У мамы был муж, который приходился мне отцом. Но у меня и в мыслях не было, что мама может так незатейливо, наставлять ему рога, посреди бела дня, да ещё при скоплении множества народа.

Мне стало любопытно, что же они там делают, и я подошёл к кабинке поближе. Стоя у шторы и прислушиваясь, я ничего не мог расслышать. Вокруг голдели люди и звуки сливались, теряясь в пространстве. Смирившись с этим, я отошёл в сторону якобы высматривая, что купить, но неизменно поглядывая в сторону примерочных. Тут неожиданно я увидел ещё пару человек, с которыми мама разговаривала. Они тоже ходили по магазинчику и что-то выбирали, косясь на кабинки с соответствующим номером. Вскоре со временем у примерочной скопилось более пяти человек. И они тупо озираясь друг на друга, не понимали, что вообще происходит. Некоторые примерочные были пусты, но никто в них не заходил из парней, ждавшие не понятно чего, как мне казалось.

И вот, этот парень, что был первый, быстро вылетев из кабинки, как ошпаренный, тут же помчался прочь, поправляя на ходу свои штаны. Я не понимал, что твориться здесь, смотря ему в след, как он удаляется. И пока у меня в голове это переваривалось, в кабинку прошмыгнул следующий из очереди, что стихийно образовалась у заманчивой для них примерочной.
