It’s often said that talent runs in the family. If that is true‚ then Wow Family Circus is a prime example. This talented bunch share some of their daring moves online‚ garnering themselves quite the following. There’s the parents‚ Ilya and Regina‚ but even more impressively‚ there’s their circus kids: Tagir (9 years old)‚ Zara (6)‚ and Iliana (4). With one quick glance at their social media accounts‚ it’s clear that this talented family trains hard to pull off daring feats (that means the rest of us should not try this at home!) Still‚ I can only imagine how much time and effort it takes to do anything even remotely close to this! @wow_family_circus Ответ пользователю @ ♬ The Greatest Show – Hugh Jackman &; Keala Settle &; Zac Efron &; Zendaya &; The Greatest Showman Ensemble Thanks to their training‚ this family has been able to take their circus act on the road. Plus‚ it seems they even have classes so they can teach other kiddos how to soar through the sky — safely‚ of course! In any case‚ I still have no idea how these kids manage to learn how to do this stuff! Daring Performances by Circus Kids Will Take Your Breath Away @wow_family_circus #acro #acrobatics #acromens ♬ Rocky – The Intermezzo Orchestra Each member of the Wow Family Circus is ridiculous talented‚ of course‚ but Zara in particular has recently garnered quite a bit of attention.

The rate at which the rare but crucial quantum phenomenon known as tunneling occurs has been measured experimentally for the first time‚ and found to match theoretical calculations. The theoretical estimates in this area had been regarded as highly uncertain‚ so confirmation in one specific case allows for greater confidence in estimating the frequency of other tunneling events.Quantum tunneling is one of the many phenomena where subatomic particles behave in ways classical physics would say is impossible. In this case‚ an object trapped in a way that classically requires a certain energy to escape leaves the trap‚ despite having less than that amount of energy. It’s a consequence‚ and proof of‚ the dual wave/particle nature of objects like electrons – a pure particle could not escape‚ but a wave occasionally can. Phenomena like alpha decay of atomic nuclei depend on quantum tunneling to occur.Tunneling is essential to quantum physics‚ and calculations based on simple examples are set in undergraduate courses. Real-world examples are considerably more complex‚ however; knowing tunneling will occasionally occur in a specific situation‚ and knowing how often‚ are very different things. In a new paper‚ a team at the Universität Innsbruck provide the first measure of the reaction between a hydrogen molecule and a deuterium anion‚ finding it to be the slowest reaction involving charged particles ever observed.Although there is no solid wall keeping deuterium anions and hydrogen molecules apart‚ physicists imagine the energy barrier as a physical wall‚ which quantum tunneling occasionally allows protons to penetrate.Image credit: Universität Innsbruck/Harald RitschThe reaction (H2 + D− → H− + HD) involves a shift between a molecule of two hydrogen atoms – protons without neutrons – and an atom consisting of a proton and neutron orbited by two electrons. After tunneling occurs‚ one of the components of the molecule has a neutron‚ while the unattached atom‚ still negatively charged‚ is neutron-less. Although it looks like a neutron has been transferred‚ the reaction is considered to represent proton exchange.Since hydrogen still makes up most of the universe‚ events like this that require no heavier elements happen very frequently on a cosmic scale‚ despite the odds in any specific encounter between hydrogen and deuterium being low. Moreover‚ if we are to have any hope of modeling more complex tunneling events we need to anchor our estimates with measures of simpler examples like this.The Innsbruck team tested the rate of occurrence experimentally by filling a trap with a mix of deuterium ions cooled to 10 K (-263°C/-441°F) (warmed by collisions to 15 K) and hydrogen gas. At these temperatures transfer is classically impossible‚ but the presence of negatively charged hydrogen ions after 15 minutes indicated it had happened‚ albeit not often.The rate is measured in cubic centimeters per second‚ giving a value of 5.2 × 10−20 cubic centimeters per second‚ with a margin of error of around a third‚ which is unlikely to mean much to anyone other than a quantum physicist.It translates‚ however to transfer occurring one in every hundred billion times a deuterium anion collides with a hydrogen molecule. This might seem too rare to worry about‚ but even a small patch of gas contains many billions of molecules. Add enough deuterium and the number of collisions becomes immense.Measuring the rate “requires an experiment that allows very precise measurements and can still be described quantum-mechanically‚” senior author Professor Roland Wester said in a statement.  The idea for the experiment came to Wester 15 years ago‚ but the tunneling is so rare it took considerable effort to construct an experiment where it could be measured. The study is published in Nature. An earlier version of this article was published in March 2023.

     All organisms are made of living cells. While it is difficult to pinpoint exactly when the first cells came to exist‚ geologists’ best estimates suggest at least as early as 3.8 billion years ago. But how much life has inhabited this planet since the first cell on Earth? And how much life will ever exist on Earth?In our new study‚ published in Current Biology‚ my colleagues from the Weizmann Institute of Science and Smith College and I took aim at these big questions.Carbon on EarthEvery year‚ about 200 billion tons of carbon is taken up through what is known as primary production. During primary production‚ inorganic carbon — such as carbon dioxide in the atmosphere and bicarbonate in the ocean — is used for energy and to build the organic molecules life needs.Today‚ the most notable contributor to this effort is oxygenic photosynthesis‚ where sunlight and water are key ingredients. However‚ deciphering past rates of primary production has been a challenging task. In lieu of a time machine‚ scientists like myself rely on clues left in ancient sedimentary rocks to reconstruct past environments.In the case of primary production‚ the isotopic composition of oxygen in the form of sulfate in ancient salt deposits allows for such estimates to be made.In our study‚ we compiled all previous estimates of ancient primary production derived through the method above‚ as well as many others. The outcome of this productivity census was that we were able to estimate that 100 quintillion (or 100 billion billion) tons of carbon has been through primary production since the origin of life.Big numbers like this are difficult to picture; 100 quintillion tons of carbon is about 100 times the amount of carbon contained within the Earth‚ a pretty impressive feat for Earth’s primary producers.Primary productionToday‚ primary production is mainly achieved by plants on land and marine micro-organisms such as algae and cyanobacteria. In the past‚ the proportion of these major contributors was very different; in the case of Earth’s earliest history‚ primary production was mainly conducted by an entirely different group of organisms that don’t rely on oxygenic photosynthesis to stay alive.A combination of different techniques has been able to give a sense of when different primary producers were most active in Earth’s past. Examples of such techniques include identifying the oldest forests or using molecular fossils called biomarkers.In our study‚ we used this information to explore what organisms have contributed the most to Earth’s historical primary production. We found that despite being late on the scene‚ land plants have likely contributed the most. However‚ it is also very plausible that cyanobacteria contributed the most.Total lifeBy determining how much primary production has ever occurred‚ and by identifying what organisms have been responsible for it‚ we were also able to estimate how much life has ever been on Earth.Today‚ one may be able to approximate how many humans exist based on how much food is consumed. Similarly‚ we were able to calibrate a ratio of primary production to how many cells exist in the modern environment.Despite the large variability in the number of cells per organism and the sizes of different cells‚ such complications become secondary since single-celled microbes dominate global cell populations. In the end‚ we were able to estimate that about 1030 (10 noninillion) cells exist today‚ and that between 1039 (a duodecillion) and 1040 cells have ever existed on Earth.How much life will Earth ever have?Save for the ability to move Earth into the orbit of a younger star‚ the lifetime of Earth’s biosphere is limited. This morbid fact is a consequence of our stars life cycle. Since its birth‚ the sun has slowly been getting brighter over the past four and half billion years as hydrogen has been converted to helium in its core.Far in the future‚ about two billion years from now‚ all of the biogeochemical fail-safes that keep Earth habitable will be pushed past their limits. First‚ land plants will die off‚ and then eventually the oceans will boil‚ and the Earth will return to a largely lifeless rocky planet as it was in its infancy.But until then‚ how much life will Earth house over its entire habitable lifetime? Projecting our current levels of primary productivity forward‚ we estimated that about 1040 cells will ever occupy the Earth.Earth as an exoplanetOnly a few decades ago‚ exoplanets (planets orbiting other stars) were just a hypothesis. Now we are able to not only detect them‚ but describe many aspects of thousands of far off worlds around distant stars.But how does Earth compare to these bodies? In our new study‚ we have taken a birds eye view of life on Earth and have put forward Earth as a benchmark to compare other planets.What I find truly interesting‚ however‚ is what could have happened in Earth’s past to produce a radically different trajectory and therefore a radically different amount of life that has been able to call Earth home. For example‚ what if oxygenic photosynthesis never took hold‚ or what if endosymbiosis never happened?Answers to such questions are what will drive my laboratory at Carleton University over the coming years.Peter Crockford‚ Assistant Professor‚ Earth Sciences‚ Carleton UniversityThis article is republished from The Conversation under a Creative Commons license.

You may have heard of the Fermi Paradox‚ but if you haven't‚ here it is in a nutshell: Given the high probability that alien life exists out there in the universe‚ why has nobody got in touch? If there are so many other civilizations out there‚ possibly at far more advanced stages than we are because of how long the universe has dragged on for (no offense universe‚ but get to the point)‚ why are they not doing what we're doing‚ sending out probes and desperately searching for other signs of life? One idea is the Great Filter. The hypothesis goes that before alien civilizations can make it to the point where they are able to leave their solar system and begin colonizing their galaxy‚ something happens to prevent them from doing so‚ or we'd see evidence for this in our own Milky Way. Whether this is the step from multi-cell life to animals that can use tools‚ or from where we are now to exploring the galaxy‚ we just don't know.What makes this so interesting is we wouldn't know if we are past the "great filter" or whether it's going to happen in our future. Could it be that most don't make it past single-cell life and we have made it past this filter? Or at some point yet to come are we‚ like other alien civilizations out there‚ about to destroy ourselves before we are able to leave Earth‚ perhaps through war or using up our resources before we can escape?Somewhat disconcertingly‚ some philosophers and scientists have suggested that this means if we were to find life on‚ say‚ Mars it would have some less-than-ideal implications for where we are in relation to the Great Filter. Oxford University philosophy professor Nick Bostrom says that he hopes the search for extraterrestrial life turns up nothing. If we found very simple life forms‚ Bostrom argued in an article published in the MIT Technology Review in 2008‚ then we could conclude that the filter happens sometime after that point of life. If we found multi-cellular life‚ this would narrow down the point at which the Great Filter could take place.Bostrom believes that in order to narrow down where the filter takes place‚ we should look at life on Earth to see which steps are improbable. "One criterion is that the transition should have occurred only once‚" he wrote. "Flight‚ sight‚ photosynthesis‚ and limbs have all evolved several times here on Earth‚ and are thus ruled out."He also argued that evolutionary features that took a long time to occur even after prerequisites were met would indicate that this evolutionary step was improbable‚ eg the original emergence of life. The step from animals to humans took place over a relatively short time period‚ geologically speaking‚ suggesting it's a weak candidate for a Great Filter event.If we were to find evidence of vertebrates on Mars (very unlikely‚ but we can dream!) he believed that would be terrible news‚ as it would suggest that the bulk of the Great Filter is still in our future‚ and we'll have to face the probability that we will go extinct before we are technologically mature enough to travel through the galaxy."Such a discovery would be a crushing blow. It would be by far the worst news ever printed on a newspaper cover‚" Bostrom wrote. "This is why I’m hoping that our space probes will discover dead rocks and lifeless sands on Mars‚ on Jupiter’s moon Europa‚ and everywhere else our astronomers look. It would keep alive the hope for a great future for humanity."So‚ though there are many other possible solutions to the Fermi Paradox that are worth looking at if you enjoy that sort of thing‚ if Bostrom is correct it means that finding evidence of advanced civilizations is good news‚ but finding the wrong stages of life that evolved independently in our own Solar System would be the worst possible news we could receive.An earlier version of this article was first published in November 2020.

Jordan Rubin‚ a legal blog writer at MSNBC‚ is getting very very nervous to the point of appearing to anxiously rub worry beads over the delay the U.S. Court of Appeals is taking to rule on Donald Trump's immunity appeal which threatens to also delay his J6 trial scheduled for March 4. Here is Rubin on Friday in a state of high anxiety over the appeal delay in "What’s taking the Trump immunity appeal ruling so long?" It’s been more than two weeks and still no word from the U.S Court of Appeals for the D.C. Circuit panel that heard argument Jan. 9. While there’s no single satisfying answer to this pressing question‚ there are some factors we can identify to help understand what’s at play. First‚ the judges know that this opinion needs to be airtight. Whatever they decide will inevitably be appealed‚ which would mean not only their colleagues on the full D.C. Circuit — in what’s known as en banc review — but also potentially Supreme Court justices reviewing their work. While some observers are eager for a ruling as soon as possible to avoid further delay of Trump’s federal election interference trial‚ which technically is set to start March 4‚ whether the opinion takes weeks instead of days isn’t the judges’ greatest concern. That said‚ the court agreed to consider the case on an expedited timeline — they didn’t do that to take months to issue a ruling‚ even if they might wish they had more time for this historic case. You can almost hear poor Rubin's worry beads rubbing against each other as he agonizes that‚ despite the case being considered on an expedited timeline‚ it is now being delayed because of what Rubin claims to possibly be annoying dissenting judges gumming up the works for liberals anxious to see the March 4 J6 trial to commence on time‚ so to imagine Trump convicted before voting in the general election begins. Of course‚ some disagreements are insurmountable‚ which leads to dissent. If a judge is intent on dissenting here‚ then that could take more time for the respective opinions to respond to one another. That is‚ if you look at decisions that have dissents in them‚ you may see majority and dissenting opinions responding to the other opinion’s position‚ which can take more time to sort out with the back-and-forth. Sometimes a dissenter can be brought along to the majority view during the drafting process. Under any of these scenarios‚ then‚ you can see what may build additional time into the process. Again‚ that doesn’t specifically answer the question of why it would take‚ say‚ three weeks instead of two weeks to reach a ruling‚ but those might be some of the things that the judges are grappling with. Rubin's current immunity appeal delay anxiety hilariously contrasts with his recent confidence on January 9 when he declared that "The D.C. Circuit is hearing the case on an expedited timeline‚ so we can expect a quick ruling."
