  • Why NASA’s James Webb Space Telescope is such a fiscal black hole

    The Hill ^ | 4/12/18 | Mark Whittington
    The announcement by NASA that launch of the James Webb Space Telescope is going to be delayed over another year, now May 2020, felt like déjà vu. When the JWST was first proposed in 1997, it was supposed to launch in 2007 and cost half a billion dollars. Now the launch date is 13 years later and the cost is at least $8.8 billion. NASA will have to go back to Congress for more money if the huge space observatory exceeds previous cost caps. In the meantime, NASA is convening an independent review board that will examine the problems that...
  • Big Bang, Big Claim: Why This Bold Idea Is Right

    At 13.8 billion years ago, our entire observable universe was the size of a peach and had a temperature of over a trillion degrees. That's a pretty simple, but very bold statement to make, and it's not a statement that's made lightly or easily. Indeed, even a hundred years ago, it would've sounded downright preposterous, but here we are, saying it like it's no big deal. But as with anything in science, simple statements like this are built from mountains of multiple independent lines of evidence that all point toward the same conclusion — in this case, the Big Bang,...

  • Out of Africa: 90,000-Year-Old Human Finger Points to Much Earlier Migration

    04/23/2018 1:03:57 PM PDT · by SunkenCiv · 93 replies
    Researchers have directly dated the earliest-ever fossil from an anatomically modern human found outside of Africa and the Levant. This 90,000-year-old fossilized finger rewrites traditional theories of early migration, beating expectations by some 25,000 years. Homo sapiens, the team thinks, were exploring what was once the wet grassland of Saudi Arabia far earlier than previously thought. Humans may not have left Africa in one big wave, but in a series of trickles... Extensive testing at institutions around the world revealed not only was this the finger bone of a modern human, but it was also the oldest directly dated Homo...

    A galactic gold rush has been predicted for some time, with experts saying teams will race against each other to collect precious metals from space rocks. Earlier this year, physicist Michio Kaku described asteroids as “flying gold mine[s] in outer space” that could replenish any metal shortage on Earth. Examples of valuable asteroids include one rock measuring 3,000ft across that contains $5.4 trillion worth of platinum. And now it is predicted the first trillionaire will make their fortune in outer space.

    Researchers have long wondered about the composition of the clouds high up in Uranus' sky — specifically, whether they're dominated by ammonia ice, as at Jupiter and Saturn, or by hydrogen sulfide ice. The answer has proved elusive, because it's tough to make observations with the required detail on distant Uranus. (Not only are Jupiter and Saturn closer to Earth, they have also hosted dedicated orbiter missions. Uranus has been visited just once — a brief flyby by NASA's Voyager 2 probe in January 1986.) Irwin and his colleagues studied Uranus' air using the Near-Infrared Integral Field Spectrometer (NIFS), an...
  • Models of star and galaxy cluster formation incorrect

    Cosmos Magazine ^ | 05 Dec, 2017 | LAUREN FUGE
    The dominant explanation of the formation of star and galaxy clusters is flawed and misrepresents the nature of time, a team of Brazilian researchers claim, in a new study that uses simulations to explain a long-standing paradox in a process called ‘violent relaxation’. Clusters of stars and galaxies are tight groups of celestial bodies shackled together by gravity. Star clusters contain up to one million stars with a common origin and are up to 30 light-years across, while collections of galaxies are among the largest structures in the Universe, composed of up to 1000 galaxies with a mass of a...

    BufferApp ^ | 21 MAR 2013/30 SEP 2016 | Leo Widrich; Jocko Manning
    One of the things I fuss about a lot (especially at Buffer) are words—very simple words, in fact. Should it say “Hi” or “Hey?” Should it be “cheers” or “thanks?” How about “but” or “and?” There are many occasions when Joel and I sit over one line and change it multiple times, until we feel it really sits right. This is partly to improve our metrics for click rate and others. It is also to simply create the right emotion. The one key question we ask ourselves is: “How does this make you feel?” The question might sound very...
  • Is Lockheed Martin working on a nuclear fusion-powered fighter jet?

    As Dr Thomas McGuire, head of Skunk Works’ Compact Fusion Project, detailed in a 2014 report, the smaller reactor is more feasible than a large-scale one. If the system functions as expected, the CFR could take 11kg of fuel in the form of the hydrogen isotopes deuterium and tritium, and run the reactor for an entire year without needing to stop. Throughout that time, it would be consistently pumping out 100MW of power, enough to power up to 80,000 homes. When discussing how it could impact aircraft design, Lockheed Martin said that this amount of power would allow it to...

Select Dead Sea Scrolls are on display at the Denver Museum of Nature & Science in Denver, Colorado, from March 16 to September 3, 2018. Perhaps the most significant archaeological discovery of the 20th century, the Dead Sea Scrolls represent the earliest extant copies of the Hebrew Bible (Old Testament). In addition to Biblical texts, the scrolls contain numerous texts, such as the War Scroll (Scroll 1QM), penned by a sectarian community.

    A probe of the brain’s reward system looks at Drosophila sex (or lack thereof) and drinking. Moody red lighting in a lab is helping researchers figure out what fruit flies like best about sex. The question has arisen as scientists try to tease out the neurobiological steps in how the brain’s natural reward system can get hijacked in alcoholism, says neuroscientist Galit Shohat-Ophir of Bar-Ilan University in Ramat Gan, Israel. Male fruit flies (Drosophila melanogaster) were genetically engineered to ejaculate when exposed to a red light. Ejaculation increased signs in the insects’ brains of a rewarding experience and decreased the...

    On Thursday, April 19, a representative from NASA announced the space agency's plans during the Space Symposium conference. NASA is now in the process of selecting a contractor to build a spacecraft called the Lunar Orbital Platform-Gateway. The federal agency is likely to concentrate on making elements that would help power the Lunar Orbital Platform-Gateway next year. NASA would be following up on building the habitual components of the Lunar Orbital Platform-Gateway with hopes that it would be able to launch to the moon around 2022. NASA officials also hope that the Lunar Orbital Platform-Gateway would be fully orbital by...

We are taken by it. The rush of seconds, hours, years that hurls us towards life then drags us towards nothingness ... We inhabit time as fish live in water. Our being is being in time. Its solemn music nurtures us,...
