This simple fitness test might predict how long you'll live
A simple test of your balance, strength and flexibility, known as the sitting-rising test, could be an early indicator of how long you'll live, according to a large-scale new study of mobility and mortality.
The study, published Wednesday in the European Journal of Preventive Cardiology, looked at how well 4,282 men and women aged between 46 and 75 could lower themselves from a standing position to the floor and then stand back up again with as little assistance as possible from their hands, knees, furniture or human helpers.

The test assesses 'all the aspects of fitness that are not aerobic,' said Claudio Gil Araújo, the study's lead author and research director at an exercise-medicine clinic in Rio de Janeiro, where the data were collected. Those aspects include muscular health, balance, flexibility and body composition, he said, each of which is important for longevity and health.
In the study, middle-aged and older people who needed no support to sit or stand were about six times less likely to die of heart disease and other cardiovascular conditions during the next decade or so than people who wobbled and had great difficulty completing the task. They also were less likely to die of other natural causes, including cancer.
There are many tests of balance or strength or flexibility, Araújo said. 'But what makes this test special is that it looks at all of them at once, which is why we think it can be such a strong predictor' of longevity, he said.

Want to try the sitting-rising test yourself? First find a partner. 'Don't do this test on your own,' Araújo said. Your partner will watch you, score your test and, most important, steady you if you start to topple. (If you have disabilities or serious joint problems, such as hip, spine or knee arthritis, you probably shouldn't do the test, Araújo said, since it could cause unnecessary pain or injury.)
Next:
-Clear a level space so you have room to maneuver but also, if needed, still have a wall, chair or other support nearby.
-If the floor is bare, put down a pad in case you land with a thump while sitting.
-Remove your shoes and socks.
-Stand with your feet slightly apart, then cross one foot in front of the other. Hold your arms however you'd like.
-Lower yourself until you're seated on the ground. Try not to wobble or use any support to get yourself settled, such as a hand, forearm or any part of your legs.
-From this seated position, stand back up, trying to remain steady and not rely on any support, including using your hands.
To score your test, start with 10 points. Your partner then subtracts one point every time you use a hand or any other support to help you lower down or rise up and half a point every time you noticeably wobble.

In the new study, men and women who scored between 0 and 4 were far more likely to die of cardiovascular problems and other natural causes during about a 12-year-long follow-up period than those scoring a perfect 10. (The scientists screened out deaths from suicides or accidents, such as car crashes, that wouldn't be considered natural causes.)
Men and women scoring between 4.5 and 7.5 had about a threefold heightened risk of dying during the follow-up period, compared to those who scored a 10.
A relatively low score, below about a 7.5 for healthy middle-aged and older people, 'should be a cause for some concern,' Araújo said. He's 69 and recently scored an 8.5, he said. (No one in the study group was older than 75, so it's not clear if the findings apply to anyone 76 or older.)
These new results update a 2014 study from Araújo's group that likewise showed an association between how people scored and their longevity. A score between 8 and 10 'indicated a particularly low risk of death' in subsequent years, Araújo and his co-authors wrote.
That study involved about 2,000 men and women and a follow-up period of about six years. The new study doubled both the participants and follow-up time, making the updated results 'that much stronger,' Araújo said.

The sitting-rising test is not a foolproof indicator of our health or longevity, though. It incorporates so many aspects of fitness, for one thing, it's hard to know which are weakest if our scores are low, said Avril Mansfield, a professor of physical therapy at the University of Toronto, who studies mobility and balance. She wasn't involved with the new study.
Is the problem mostly our flexibility, strength, range of motion, balance or some combination of several of those? 'Working with a professional like a physiotherapist or a clinical exercise specialist could help you identify the specific physical limitations' that are impairing your score, she said, 'and design an exercise program to address those limitations.'
This test also could be daunting or inappropriate for many people, said Lora Giangregorio, a professor at the University of Waterloo in Canada who studies falls and bone health and wasn't involved with the study. 'It requires people to get off of the floor in a prescribed way that requires very good joint mobility.'
If you have joint pain or other disabilities or are older and feel infirm, other tests of mobility are likely to be safer and more reliable, she said. Try, for instance, the 30-second chair stand test, which is recommended by the Centers for Disease Control and Prevention to assess physical performance in older people, she said. Simply count how many times you can rise from and sit back onto a chair seat in 30 seconds, without using your hands. Men younger than 60 should manage, at minimum, 15 and women that age at least 13. Average scores decline by one or two per decade after that.
The sitting-rising test and the new study also don't tell us why the test predicts mortality, although Araújo believes low scores indicate underlying disease and frailty. People who are inflexible also often have stiff arteries, he said, contributing to heart disease, while people with poor balance could be predisposed to serious falls, which can precipitate physical decline and death.
Perhaps most important, though, a low score is a portent, but not a promise, he said. 'People ask me all the time, 'If my score is low, does that mean I'll be dead in five years?' I tell them, 'Of course not,'' Araújo said. But it can be a wake-up call, he added. 'It's telling you, maybe you need to make some changes.'

How Astronomers Will Deal With 60 Million Billion Bytes of Imagery
It was not that long ago that astronomers would spend a night looking through a telescope, making careful observations of one or a few points of light. Based on those few observations, they would extrapolate broad generalizations about the universe. 'It was all people could really do at the time, because it was hard to collect data,' said Leanne Guy, the data management scientist at the new Vera C. Rubin Observatory. Rubin, located in Chile and financed by the U.S. Department of Energy and the National Science Foundation, will inundate astronomers with data. Each image taken by Rubin's camera consists of 3.2 billion pixels that may contain previously undiscovered asteroids, dwarf planets, supernovas and galaxies. And each pixel records one of 65,536 shades of gray. That's 6.4 billion bytes of information in just one picture. Ten of those images would contain roughly as much data as all of the words that The New York Times has published in print during its 173-year history. Rubin will capture about 1,000 images each night. As the data from each image is quickly shuffled to the observatory's computer servers, the telescope will pivot to the next patch of sky, taking a picture every 40 seconds or so. It will do that over and over again almost nightly for a decade. The final tally will total about 60 million billion bytes of image data. That is a '6' followed by 16 zeros: 60,000,000,000,000,000. Rubin's 3.2 Gigapixel Camera At the heart of the Rubin observatory is the largest digital camera in the world, a supercooled grid with hundreds of high-resolution sensors. See how the camera works.

The Rubin Observatory is throwing a big party to reveal its first pictures — and you're invited
After more than 20 years of planning and construction, the Vera C. Rubin Observatory is ready for its grand opening, and the world is invited. The observatory in the foothills of the Chilean Andes features a monster of a telescope, with an 8.4-meter-wide (28-foot-wide) mirror, coupled with what's said to be the world's largest digital camera. It will survey the night sky every night for at least 10 years, producing about 20 trillion bytes of data every 24 hours. It would take you more than three years of watching Netflix, or over 50 years of listening to Spotify, to use that amount of data, according to the Rubin team. The first images and videos are due to be unveiled on Monday, during a 'First Look' webcast that will be shared online and at more than 300 in-person watch parties across the globe. What will the images look like? Mario Juric knows, but he isn't telling. 'I cannot tell you what's on them, but I can tell you we just finished them, and they look amazing,' Juric, a member of the Rubin team and the director of the University of Washington's DiRAC Institute, says on the Fiction Science podcast. 'I did not spend a day doing what I was supposed to be doing, because I just spent it browsing through the images. … I could teach an entire class by just zooming in on different parts of this image and explaining what this object is.' There could be a lot of teachable moments ahead: The observatory's Simonyi Survey Telescope is expected to detect millions of previously unseen celestial bodies in our solar system, potentially including a hypothetical world known as Planet X or Planet 9. It'll serve as an early warning system for transient cosmic phenomena such as supernovas or gamma-ray bursts. And it could help scientists shed new light on the mysteries behind dark energy and dark matter. Mario Juric (UW Photo) The dark matter angle is particularly apt, because the observatory is named after the late Vera Rubin, an astronomer who analyzed the rotation rates of galaxies to come up with some of the most solid evidence we have that invisible dark matter exists. Even before Rubin died in 2016, her fellow scientists were laying the groundwork for the observatory that would eventually bear her name. In 2003, they started discussing potential sites for what was then called the Large Synoptic Survey Telescope, or LSST. Juric recalls attending one of the early discussions in Seattle. At the time, astronomers were just finishing up a successful project known as the Sloan Digital Sky Survey. 'People were asking, what do we build next? What's the next major step in this idea to go and digitize the cosmos?' Juric says. 'And the idea was to build something like Rubin.' In 2008, the project received a $30 million boost from Microsoft executive Charles Simonyi and the company's co-founder, Bill Gates. Eventually, the National Science Foundation and the U.S. Department of Energy kicked in hundreds of millions of dollars to support the observatory's construction in Chile. Turning data into discoveries The observatory's Simonyi Survey Telescope features a unique three-mirror design that maximizes the instrument's field of view. It's made to move across a swath of sky in just a few seconds, allowing the LSST Camera to capture a 3,200-megapixel image in 15 seconds and then switch to take the next image five seconds later. That speed makes it possible for the observatory to map the sky in high resolution every three days. It takes less than 60 seconds to transfer each image over fiber-optic cables from Chile to the SLAC National Accelerator Laboratory in California for an initial round of processing. The flood of imagery is distributed to data centers around the world, and scientists can access and filter the data through an online portal. Astronomical data analysis is the specialty of UW's DiRAC Institute. Its name is an acronym, standing for Data-intensive Research in Astrophysics and Cosmology. Astronomers have traditionally been 'physicists who look up,' Juric says, but he argues that working with Rubin's rush of data will require a new set of skills — the kinds of skills that are being taught at the DiRAC Institute. 'You now need to become a data scientist, and you need to become a really good statistician,' he says. 'That's the kind of background that you're going to need to make sense out of all these data that Rubin is going to deliver to us.' A software tool that Juric helped develop, known as Sorcha, hints at the enormity of the task ahead. Sorcha makes predictions about how much data will be generated by the Rubin Observatory, and how many discoveries could be made as a result. 'The number that I like to quote is, it took all of mankind about … 225 years to discover the first one and a half million asteroids. And in less than two years, Rubin is going to double that, and then go on and triple that a few years later,' Juric says.

What about Planet 9, which astronomers have been trying to detect on the edge of the solar system for more than 10 years? 'If it's out there, we have something like a 70 or 80% chance to find it,' Juric says. 'Even if we don't directly notice it, my guess is in about three years or so, that's how much time it will take us to accumulate this data to sufficient precision [that] we'll confidently be able to say whether it is there and just really, really hard to find — or whether this whole thing has been just us astronomers hoping a little bit too much.' There's even a chance that the Rubin Observatory will pick up evidence of alien signals. Some astronomers, including UW's James Davenport, have speculated that Rubin could detect anomalous patterns that might be associated with extraterrestrial spaceships. 'The nice thing with this telescope is, we're going to collect so much data that we'll be able to go and look for these rare, unusual, anomalous signals. And who knows, maybe one of them is an E.T. shining a laser at us,' Juric says. 'It'll be fun.' The fun begins at 8 a.m. PT on Monday when the First Look webcast goes online. 'A couple of days after that, on the 26th, we're going to have an extended version of that for the general public on the UW Seattle campus, at Kane Hall,' Juric says. 'We really invite everyone here from Seattle or the Pacific Northwest, however far you want to drive, to come over and see that with us in person.' The in-person event on June 26 will start at 7 p.m. and feature an hourlong presentation about Rubin's first images. Speakers will include Juric as well as UW astronomer Zeljko Ivezic, director of Rubin construction; and Andrew Connolly, who was the DiRAC Institute's founding director and is now the director of UW's eScience Institute. Juric expects the fun, and the hard work of discovery, to continue for at least the next decade. 'Rubin should have the kind of impact that when we look at textbooks 10 years from now, almost every textbook has to change something because Rubin has added to that piece of human knowledge,' he says. 'It's a fairly high bar to meet, but it is a big, expensive telescope. That's what we're aiming for: It's got to be transformational.'
