In fairness, he did have a lot on his mind.Our experience of space, which started with Russian cosmonaut Yuri Gagarin in April 1961, was still quite limited when Apollo 8 made a trip 'round the moon in December 1968, the first time humans had ever broken free of Earth's orbit.But after a total of six moon landings for the Apollo program in less than four years, that was it.NASA spent the next several decades focusing its manned spaceflight efforts on the space shuttle and on missions to the International Space Station.Meanwhile, Amazon founder Jeff Bezos and SpaceX founder Elon Musk also have their eyes on lunar adventures.The Apollo missions needed roughly three days' travel time each way -- Apollo 11 got from Earth to lunar orbit at midday on day three of its mission.

The English rock band Joy Division released their debut studio album “Unknown Pleasures” 40 years ago.To mark the anniversary of the album, we recorded a signal from the same pulsar with a radio telescope in Jodrell Bank Observatory, only 14 miles (23 km) away from Strawberry Studios where the album was recorded.Peter Saville – graphic designer and co-founder of Factory Records – designed the album cover based on a picture spotted by band member Bernard Sumner in an encyclopedia.The picture itself can be traced to the work of the postgraduate student Harold Craft, who published the image in his PhD thesis in 1970.What we see in this enigmatic image is the signal produced by a pulsar known as B1919+21, the first pulsar ever discovered.A pulsar is formed during the violent death of a star several times more massive than our sun.

The newest Star Wars Luke Skywalker action figure, unveiled during San Diego Comic-Con 2019, promises to look super Skywalker-ey with its realistic rubber exterior skin and internal skeletal structure that makes for poses that can be held.Hasbro's Skywalker joins the toy maker's Star Wars: The Black Series Hyperreal line, which so far includes an 8-inch Darth Vader.The figures are higher end than the standard figures in the Black Series line, with seamless joints and 28 points of hyper-articulation that allow for a variety of poses.The Hyperreal line was inspired by the growing popularity of toy photographs on Instagram and the desire to make those pictures look more realistic, the designers have said."Stop-motion maquettes were definitely part of what spawned the internal structure," Patrick Schneider, Star Wars senior brand manager, told StarWars.com."We wanted something was going to not only be posable, but would also hold that pose.

The new 2020 Corvette may have a hybrid in its not-too-distant future, with Chevrolet refusing to shut down chatter of electrified versions of the brand new sports car.Revealed this week, the eighth-generation 2020 Corvette Stingray has a 6.2-liter naturally-aspirated V8, which Chevy has dubbed the LT2.However, it’s also set the mid-engined car’s platform up to accommodate very different drivetrains.The Stingray may be expected to start at under $60,000, but it still delivers as much as 495 horsepower and 470 lb-ft of torque.That’s much in line with previous Corvette strategy.What would be new – and arguably more interesting – is a hybrid Corvette, or even a fully-electric Corvette.

Sometimes, all it takes to make a transmission better is a little bit of programming.That's the case with Hyundai's latest transmission tech, which aims to not only improve shift times, but also the general driving experience.Hyundai this week unveiled its Active Shift Control technology.By the sounds of it, ASC is largely based on an update to the shift control logic in the hybrid system's control unit.It monitors the transmission 500 times per second and tells the electric motor in the hybrid powertrain when to align the engine's and transmission's rotational speeds.According to Hyundai, the benefits are twofold.

Humans have been getting tattoos since ancient days, but modern science is giving them a new purpose: health condition monitoring.Researchers have detailed a new type of permanent tattoo that changes color when certain health biomarkers in the body change, offering visual indicators that something is wrong and the patient needs to visit their doctor.The new diagnostic tool was developed by researchers in Germany and recently published as a study in the journal Angewandte Chemie.Though both appear similar when injected into the skin as a tattoo, the newly detailed health tattoo features a colorimetric analytic formulation instead of typical tattoo ink.Three colorimetric chemical sensors were adapted to produce different colors when certain biomarkers in the body changed.One ‘ink’ changes from yellow to blue when the body’s pH level changes from five to nine.

In a move that is bound to piss off more than a couple of publishers, Google is readying to fix the “loophole” that allowed sites to see when you’re browsing in Incognito Mode.Google announced in a blog post on Thursday that the update will arrive with the release of Chrome 76 on July 30.The tip-off to sites that you’re browsing in private mode is an unintended result of Chrome’s FileSystem API, which is disabled in Incognito.If a site searches for the FileSystem API and determines it’s disabled, it can, as Google puts it, “give the user a different experience.”News of this kind of behaviour by websites has been cropping up for years, and it’s a huge pain in the ass if you’re, say, trying to get around a publisher’s paywall.But while it’s kind of a bummer for publishers if they can’t force you to log in, subscribe, or switch to a normal browsing mode, Google notes there are serious circumstances under which Incognito Mode users might need to protect their privacy, including political oppression or domestic abuse.

Success in all funding lines of the German Excellence Strategy competition: after the positive funding decision for two Clusters of Excellence in September 2018, the University of Konstanz has now once again been selected as one of eleven universities or university consortia that will receive funding as Universities of Excellence in Germany.The university's concept "University of Konstanz - creative.together" will therefore receive funding in the context of the Universities of Excellence funding line of the German Excellence Strategy over the next seven years.We are ecstatic and very proud that our institutional strategy and our achievements were recognized again", says Professor Kerstin Krieglstein, Rector of the University of Konstanz.The new concept "creative.together" builds on the previous university strategy and further develops its "culture of creativity" in a systematic way.The university has positioned itself as a young campus and reform university, while building its reputation as both a place for encounters and exchange as well as a Denkwerkstatt where new ideas are developed and put into practice.As a pioneer in the promotion of early career researchers, the university's Zukunftskolleg facilitates independent research in an international, intergenerational and interdisciplinary community.

“There will be significant process and technology costs associated with aggregation, cleaning, curating, hosting, analyzing and protecting the transformation of these raw data records”NHS data – held in some 55 million patient records – could be worth £5 billion each year to commercial partners, consultancy EY said in a new report published Friday, highlighting a further £4.6 billion in annual potential benefits to patients if the datasets of the single largest integrated health care provider in the world were put to use.The latter could be realised through operational savings, and wider economic benefits generated through “Big Data”, AI and personalised medicine, EY claimed.The report by EY’s Pamela Spence, from the company’s Global Health Sciences division, notes that creating a curated, accessible NHS dataset would be no mean feat, even before policy makers are brought round and privacy issues are tackled.Cleaning and Curating Would Come with “Significant Costs”“There will be significant process and technology costs associated with aggregation, cleaning, curating, hosting, analyzing and protecting the transformation of these raw data records into a consolidated longitudinal patient-level dataset,” she wrote.

Simulations from researchers in Japan provide new insights into the reactions occurring in solid-oxide fuel cells by using realistic atomic-scale models of the active site at the electrode based on microscope observations as the starting point.Extremely promising for the clean and efficient electricity generation, solid-oxide fuels cells produce electricity through the electrochemical reaction of a fuel with air, and they have already begun to find their way into homes and office buildings throughout Japan.The oxide ions then travel through an electrolyte to the other side of the device, where they react with the fuel and release their extra electrons.These electrons flow through outside wires back to the starting side, thereby completing the circuit and powering whatever is connected to the wires.Although this overall reaction is well known and relatively simple, the reaction step limiting the overall rate of the process remains controversial because the complicated structures of the electrodes--which are generally porous materials as opposed to simple, flat surfaces--hinder investigation of the phenomena at the atomic level.Since detailed knowledge about the reactions occurring in the devices is vital for further improving the performance and durability of fuel cells, the challenge has been to understand how the microscopic structures--down to the alignment of the atoms at the different interfaces--affect the reactions.

We've known about the 2020 Cadillac CT5 for quite some time, but one of the last pieces in the puzzle that we didn't know for sure was its price.Certainly, a brand spanking new replacement for the Cadillac CTS can't be too inexpensive, right?As it turns out, it's still pretty affordable.The 2020 Cadillac CT5 will start at $37,890, including destination.That will net you a base CT5 Luxury, but there's loads of standard equipment on this entry-level trim, including a 10-inch touchscreen infotainment system, keyless entry, active noise cancellation and a suite of safety features that include automatic braking and a rear-seat alert.Rear-wheel drive is standard on the CT5, and moving up to AWD changes the price to $40,490, but it adds standard heated seats and a heated steering wheel, too.

Computer vision has improved massively in recent years, but it’s still capable of making serious errors.So much so that there’s a whole field of research dedicated to studying pictures that are routinely misidentified by AI, known as “adversarial images.” Think of them as optical illusions for computers.But while a lot attention in this field is focused on pictures that have been specifically designed to fool AI (like this 3D printed turtle which Google’s algorithms mistakes for a gun), these sorts of confusing visuals occur naturally as well.To demonstrate this, a group of researchers from UC Berkeley, the University of Washington, and the University of Chicago, created a dataset of some 7,500 “natural adversarial examples.” They tested a number of machine vision systems on this data, and found that their accuracy dropped by as much as 90 percent, with the software only able to identify just two or three percent of images in some cases.You can see what these “natural adversarial examples” look like in the gallery below:In an accompanying paper, the researchers say the data will hopefully help train more robust vision systems.

Perhaps because the Watergate scandal left America distrustful of the government, and perhaps because Kaysing’s time with Rocketdyne (which supplied NASA with engines for the Saturn rocket), the book struck a chord with a small but fervent slice of the population (a 2001 Gallup poll estimated that 6 percent of Americans doubted the authenticity of the lunar landing).He includes a picture from the landing with the pitch-black void in the background, a caption asking “Stars?A theory that a pizza parlor was actually a front for a child sex-slave facility led to an armed man entering the restaurant and demanding the release of the children.In the ‘90s, one imagines that PizzaGate may have been limited to a dingy Geocities page buried in the dark corners of the web.Users on Facebook and Twitter who find themselves enchanted by a conspiratorial work can distribute it to everyone they know, and all of those people can distribute it to everyone they know, a viral transmission with no input or oversight.Emotional bonding and intellectual exchange were the vision of the Facebook era, and for a while in the early 2010s, which seemed to be a good thing.
