    for the first time, scientists at Stanford and SLAC have created a silicon chip that can accelerate electrons—albeit at a fraction of the velocity of that massive instrument—using an infrared laser to deliver, in less than a hair's width, the sort of energy boost that takes microwaves many feet.

    This image, magnified 25,000 times, shows a section of a prototype accelerator-on-a-chip. The segment shown here are one-tenth the width of a human hair. The oddly shaped gray structures are nanometer-sized features carved in to silicon that focus bursts of infrared laser light, shown in yellow and purple, on a flow of electrons through the center channel. As the electrons travel from left to right, the light focused in the channel is carefully synchronized with passing particles to move them forward at greater and greater velocities. By packing 1,000 of these acceleration channels onto an inch-sized chip, Stanford researchers hope to create an electron beam that moves at 94 percent of the speed of light, and to use this energized particle flow for research and medical applications.

    Scientists may have stumbled upon a previously unknown class of massive collision in the universe. 

    On Monday, researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced that they had yet again detected ripples in space-time. They think these particular disturbances in the fabric of the universe - which were observed in April 2019 - came from the collision of two neutron stars, the super-dense remnants of dead stars.

    This article has some really amazing pictures/photos too.

    This supercomputer simulation shows one of the most violent events in the universe: a pair of neutron stars colliding, merging and forming a black hole. A neutron star is the compressed core left behind when a star born with between eight and 30 times the sun's mass explodes as a supernova. Neutron stars pack about 1.5 times the mass of the sun — equivalent to about half a million Earths — into a ball just 12 miles across. NASA Goddard

    Iranian plane crash

    Quote

    The Ukrainian flight that crashed just outside the Iranian capital of Tehran was struck by an anti-aircraft missile system, a Pentagon official, a senior U.S. intelligence official and an Iraqi intelligence official told Newsweek. None of the officials was authorized to speak publicly on the matter. 

    Ukraine International Airlines Flight 752, a Boeing 737–800 en route from Tehran Imam Khomeini International Airpot to Kyiv's Boryspil International Airport, stopped transmitting data Tuesday just minutes after takeoff and not long after Iran launched missiles at military bases housing U.S. and allied forces in neighboring Iraq. The aircraft is believed to have been struck by a Russia-built Tor-M1 surface-to-air missile system, known to NATO as Gauntlet, the three officials told Newsweek.

    Trump now wants US and Iran to work together

    Quote

    President Donald Trump said that the United States and Iran should work together against their common foe of the Islamic State militant group (ISIS), hoping the Islamic Republic would change course after the latest incident in the dramatic escalation of tensions in which Iran launched missiles at Iraqi military bases hosting U.S. and allied troops.

    Also, as pointed out in the OP, it's not the Mosquitoe that kills, it's the parasite it carries. 

    What about humans? Everything else seems to get along just fine until we show up and f**k it up. Having said that, the majority of people are kind and respectful, so maybe just a healthy purge instead. 🤑🥊 (joking of course)

    About 790,000 years ago, a meteor slammed into Earth with such force that the explosion blanketed about 10% of the planet with shiny black lumps of rocky debris. Known as tektites, these glassy blobs of melted terrestrial rock were strewn from Indochina to eastern Antarcticaand from the Indian Ocean to the western Pacific. For more than a century, scientists searched for evidence of the impact that created these pitted blobs.

  6. I agree completely, although there is some good quality channels on YouTube, if you don't understand the details and are just a layman it can be hard to tell if it's real or just a hypothesis. 

    But if you think their bad, you should see some of the stuff on Quora :lol:


  7. Iran plane crash. Experts doubt 'Technical failure'.

    Quote

    Doubts have been cast over Iranian claims that a plane crash near Tehran was the result of technical failures, with experts saying a "shootdown" was the most likely reason...."This is catastrophic and not the type of crash that comes from an engine failing...."It is very unusual, you would expect to see some wreckage but all we can see here is debris."

    What a wonderful start to the new year. A new war. 


  8. The brain has it's limitations just like everything else. But there impressive nonetheless. 

    Quote

    The human brain may be able to hold as much information in its memory as is contained on the entire Internet, new research suggests.

    Researchers discovered that, unlike a classical computer that codes information as 0s and 1s, a brain cell uses 26 different ways to code its "bits." They calculated that the brain could store 1 petabyte (or a quadrillion bytes) of information.

  9. Not sure if this will help you or not.

    Some of these are online and some are international, and they're expensive too.

    Edit- just read your OP title, 1-2 weeks. These will be useless then. Sorry. :wacko:

     

     


  10. A - Yes, it's called 'thinning', but it's controversial. Quick search found this from 2009.

    Quote- "Fire-science experts say that overgrown forests must be thinned. Environmentalists say that thinning is really an excuse to engage in destructive logging. And then everybody heads to court".

    https://www.csmonitor.com/Environment/Bright-Green/2009/0902/wildfires-the-causes-and-solutions

    B- I imagine this would require so much removal of forest when added up you'd run into the same problems as A.

     

     


  11. Not likely soon, but...

    New research has put forward another idea for what such a radical stellar engine might look like.

    Via this beautiful video via Kurgesagt you can learn all about the so-called Caplan Thruster, which would use the Sun's own energy to propel it across the galaxy and beyond. It's named after the scientist who came up with the design, astrophysicist Matthew Caplan from Illinois State University.
     

    ....The Caplan Thruster would sit close to the Sun, using electromagnetic fields to gather hydrogen and helium from the solar wind to use as fuel. That would power two jets of energy – one using helium, pushed through a fusion reactor to create a jet of radioactive oxygen that would move the Caplan Thruster forward, and one using hydrogen, to maintain distance from the Sun and to push it forward. The Caplan Thruster would essentially act as a kind of tugboat.

    The XENON1T detector has allowed scientists to observe an ultra-rare event: the radioactive decay of xenon-124.

     

    Quote

    In a subterranean laboratory, about a mile below Italy's Gran Sasso mountains, scientists are hunting for dark matter using an incredibly powerful detector full of liquid xenon. In their search for the elusive particle, they observed something else entirely.

    Their dark matter detector witnessed the rarest event ever recorded: the radioactive decay of xenon-124.

  13. Charles Darwin's work was based on observation and research over many years. 

    Quote

    Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species...

    His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author.[18]

     


  14. Let me get this right, You think nuclear and alien technology couldn't destroy a Pyramid? Why would aliens travel all this way and only bring one bomb :confused:

    And the reason people put themselves so deep into the soil is usually because they've died. So no need to worry about aliens or a nuclear attack. :-p

    1. Metametaphysics

      Metametaphysics is a branch of philosophy that explores the foundations of metaphysics. "Metaphysics is concerned with the foundations of reality. It asks questions about the nature of the world, such as: Aside from concrete objects, are there also abstract objects like numbers and properties? Does every event have a cause? What is the nature of possibility and necessity? When do several things make up a single bigger thing? Do the past and future exist? And so on. Metametaphysics is concerned with the foundations of metaphysics. It asks: Do the questions of metaphysics really have answers? If so, are these answers substantive or just a matter of how we use words? And what is the best procedure for arriving at them—common sense? Conceptual analysis? Or assessing competing hypotheses with quasi-scientific criteria?"

     


  16. U.K. police officers aren't above the law. Can't find a recent survey, I think they do them every five years. From 2015:-

    Quote

    A total of 1,629 police officers were arrested in the last five years for criminal offences which included assault, grievous bodily harm, and manslaughter, report the Sunday Times. Out of these, 500 were convicted of offences, or suspended from duty on suspicion of committing offences.

    Officers convicted of offences

    • PC Keith Wallis was jailed for 12 months for lying about witnessing an altercation in Downing Street involving the former Tory chief whip, Andrew Mitchell.
    • Osman Iqbal was given 7 years of jail time for prostitution, supplying a class-A drug, and money laundering in 2014.
    • Chris Higgs admitted to 16 crimes, including blackmail, fraud, perverting the court of justice, and witness interference, in March 2015.
    • Constable Trevor Jones jailed for 14 months after bombarding vulnerable women with sleazy text and voice messages in June 2015.
