    Is it a message from far beyond out own galaxy? A brief mysterious pulse detected by Arecibo telescope has baffled boffins. The discovery of a split-second burst of radio waves by scientists using the Arecibo radio telescope in Puerto Rico raises major new questions over what caused it. The finding by an international team of astronomers, published July 10 in The Astrophysical Journal, marks the first time that a so-called 'fast radio burst' has been detected using an instrument other than the Parkes radio telescope in Australia.

    Dr. Luce Irigaray has presented a philosophical statement that likely no other person has ever even considered: that E=Mc˛, the famed equation by Albert Einstein, is "sexed." Irigaray, who describes herself as a "Feminist Philosopher," wrote her thoughts in the 1987 book Parler n’est jamais neutre. The quote was listed proudly recently by her current employer, The European Graduate School, as a cutting-edge example of their faculty's thinking. The quote itself is as incoherent as it sounds, but we have decided to post it in its entirety below to make certain that all context is given: "Is E=Mc˛ a sexed...

    Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel, have you seen the movie "Interstellar?") and, if that were true, it would be "stable and navigable." This is the hypothesis put forward in a study published in Annals of Physics and conducted with the participation of SISSA in Trieste. The paper, the result of a collaboration between Indian, Italian and North American researchers, prompts scientists to re-think dark matter.

    A pulsar, one of deep space’s spinning “lighthouses”, has faded from view because a warp in space-time tilted its beams away from Earth. The tiny, heavy pulsar is locked in a fiercely tight orbit with another star. The gravity between them is so extreme that it is thought to emit waves and to bend space - making the pulsar wobble. By tracking its motion closely for five years, astronomers determined the pulsar’s weight and also quantified the gravitational disturbance. Then, the pulsar vanished. Its wheeling beams of radio waves now pass us by, and the researchers have calculated that this...

    The idea underlying string unification is as simple as it is seductive. Since the early 20th century, nature’s fundamental constituents have been modeled as indivisible particles—the most familiar being electrons, quarks and neutrinos—that can be pictured as infinitesimal dots devoid of internal machinery. String theory challenges this by proposing that at the heart of every particle is a tiny, vibrating string-like filament. And, according to the theory, the differences between one particle and another—their masses, electric charges and, more esoterically, their spin and nuclear properties—all arise from differences in how their internal strings vibrate. Much as the sonorous tones of...

Dubbed the compact fusion reactor (CFR), the device is conceptually safer, cleaner and more powerful than much larger, current nuclear systems that rely on fission, the process of splitting atoms to release energy. Crucially, by being “compact,” Lockheed believes its scalable concept will also be small and practical enough for applications ranging from interplanetary spacecraft and commercial ships to...

    Lockheed Martin, the aerospace and defense conglomerate based in Bethesda, Md., is claiming to have made a major breakthrough in nuclear fusion, which could lead to development of reactors small enough to fit on the back of a truck within a decade. In the simplest terms, nuclear fission breaks a single atom into two whereas nuclear fusion combines two atoms into one. Fusion, the holy grail of nuclear power, creates three to four times as much energy as fission. More importantly, fusion’s key advantage over fission is that it does not produce cancer-causing radioactive waste. (VIDEO-AT-LINK)Tom McGuire, who heads the...

    Fusion energy almost sounds too good to be true – zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply. Perhaps the biggest roadblock to adopting fusion energy is that the economics haven't penciled out. Fusion power designs aren't cheap enough to outperform systems that use fossil fuels such as coal and natural gas. University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output. The...

    New research from the University of Western Australia reveals that the amount of dark matter in the Milky Way is half as much as previously thought. Australian astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800,000,000,000 (or 8 x 1011) times the mass of the Sun. They probed the edge of the Milky Way, looking closely, for the first time, at the fringes of the galaxy about 5 million billion kilometers from Earth. Astrophysicist Dr Prajwal Kafle, from The University of Western Australia node of the...

    In 1909, Ernest Rutherford, Hans Geiger and Ernest Marsden took a piece of radium and used it to fire charged particles at a sheet of gold foil. They wanted to test the then-dominant theory that atoms were simply clusters of electrons floating in little seas of positive electrical charge (the so-called ‘plum pudding’ model). What came next, said Rutherford, was ‘the most incredible event that has ever happened to me in my life’. Despite the airy thinness of the foil, a small fraction of the particles bounced straight back at the source – a result, Rutherford noted, ‘as incredible as...

    The new Majorana particle showed up inside a superconductor, a material in which the free movement of electrons allows electricity to flow without resistance. The research team, led by Ali Yazdani of Princeton University, placed a long chain of iron atoms, which are magnetic, on top of a superconductor made of lead. Normally, magnetism disrupts superconductors, which depend on a lack of magnetic fields for their electrons to flow unimpeded. But in this case the magnetic chain turned into a special type of superconductor in which electrons next to one another in the chain coordinated their spins to simultaneously satisfy...

    Neil deGrasse Tyson faked a Bush quote and belatedly apologized for it after the resulting controversy spilled into the Washington Post. But true to Tysonism, his apology consisted of various empty profundities and self-promotion climaxing in… I will still mention Islamic Extremists flying planes into buildings in the 21st century. I will still contrast it with the Golden Age of Islam a millennium earlier. And I will still mention the President’s quote. But instead, I will be the one contrasting what actually happened in the world with what the Bible says: The Arabs named the stars, not God. Tyson is...

    The Federalist ^ | September 27, 2014 | Mollie Hemingway
    Popular scientist Neil deGrasse Tyson responded publicly to an email sent by Sean Davis of The Federalist. You can read it in its entirety on Facebook. To quickly review the situation that’s been unfolding in recent weeks, Sean found significant problems in various claims that Tyson makes as part of his public presentations on science. A newspaper headline touted for years by Tyson likely doesn’t exist. The exact quote he uses to bash members of Congress as being stupid also doesn’t exist. The details within one of Tyson’s favorite anecdotes — a story of how he bravely confronted a judge...

    ... Well, even 90 years isn't enough, it seems, so right now, we are entering new waters – the denial of some basic results of general relativity, our modern theory of gravity that has been around and available to everyone since 1916. So in the last week, hundreds of publications informed their readers that it's been "mathematically proven" that the big bang theory is wrong and the black holes don't exist. These nutty claims boil down to some papers by a crackpot named Ms Laura Mersini-Houghton (no, I really, really won't accept her doctorate) who had previously claimed that she...

    Inflation is dead, long live inflation! The very results hailed this year as demonstrating a consequence of inflationary models of the universe – and therefore pointing to the existence of multiverses – now seem to do the exact opposite. If the results can be trusted at all, they now suggest inflation is wrong, raising the possibility of cyclic universes that existed before the big bang. In March experimentalists announced that primordial gravitational waves had been discovered. The team behind the BICEP2 Telescope in Antarctica had observed telltale twists and turns in the polarisation of the cosmic microwave background radiation (CMB)...

    Here's one certain sign that something is very wrong with our collective mind: Everybody uses a word, but no one is clear on what the word actually means. One of those words is "science." Everybody uses it. Science says this, science says that. You must vote for me because science. You must buy this because science. You must hate the folks over there because science. Look, science is really important. And yet, who among us can easily provide a clear definition of the word "science" that matches the way people employ the term in everyday life? So let me explain...
