    Types of Repressed Memory Cases At the heart of repressed memory cases is a fundamental set of assumptions: That people routinely banish traumatic experiences from consciousness because they are too horrifying to contemplate; that these forgotten experiences cannot be recalled by any normal process but only by special techniques; that these special techniques produce reliable recovery of memory; that before such recovery, these forgotten experiences cause miserable symptoms; that healing is possible only by digging out and reliving the forgotten experiences. In point of fact there is no cogent scientific support for this repression folklore, and and ample reason to...

    The researchers, from the College's Department of Materials Science and Engineering, report that the MXene titanium carbide can be dissolved in water to create an ink or paint. The exceptional conductivity of the material enables it to transmit and direct radio waves, even when it's applied in a very thin coating. "We found that even transparent antennas with thicknesses of tens of nanometers were able to communicate efficiently," said Asia Sarycheva, a doctoral candidate in the A.J. Drexel Nanomaterials Institute and Materials Science and Engineering Department. "By increasing the thickness up to 8 microns, the performance of MXene antenna achieved...

    Feeding knowledge directly into your brain, just like in sci-fi classic The Matrix, could soon take as much effort as falling asleep, scientists believe. Researchers claim to have developed a simulator which can feed information directly into a person’s brain and teach them new skills in a shorter amount of time, comparing it to “life imitating art”. They believe it could be the first steps in developing advanced software that will make Matrix-style instant learning a reality. In the neo-noir sci-fi classic, protagonist Neo is able to learn kung fu in seconds after the martial art is ‘uploaded’ straight to...

    The suspense is over: Two tiny hopping robots have successfully landed on an asteroid called Ryugu — and they've even sent back some wild postcards from their new home. The tiny rovers are part of the Japan Aerospace Exploration Agency's Hayabusa2 asteroid sample-return mission. Engineers with the agency deployed the robots early Friday (Sept. 21), but JAXA waited until today (Sept. 22) to confirm the operation was successful and both rovers made the landing safely. The rovers are part of the MINERVA-II1 program, and are designed to hop along the asteroid's surface, taking photographs and gathering data. In fact, one of the...

    Did the octopus evolve its unique intelligence by playing fast and free with the genetic code? Elizabeth Finkel investigates -BIG snip- How did the octopus get so smart? Some 400 million years ago, cephalopods – creatures named for the fact that their heads are joined to their feet – ruled the oceans. They feasted on shrimp and starfish, grew to enormous sizes like the six-metre long Nautiloid, Cameroceras, and used their spiral-shaped shells for protection and flotation. Then the age of fishes dawned, dethroning cephalopods as the top predators. Most of the spiral-shelled species became extinct; modern nautilus was one...

    Actual title: "This ice-covered Icelandic volcano may emit more carbon dioxide than all of the country’s other volcanoes combined" Despite being mostly smothered by a glacier averaging 200 meters thick, one of Iceland’s largest and most active volcanoes still manages to belch surprisingly large quantities of carbon dioxide (CO2) into the atmosphere, new research reveals. To help lift the veil on Katla (center right, above), which lies near the southernmost tip of Iceland, researchers flew a sensor-laden aircraft around the peak at low altitude three times in 2016 and 2017. At some points near the volcano, CO2 levels were about...

    In this mini world, the concepts of "before" and "after" dissolve, such that two events can both precede and succeed each other. In other words, event A can occur before event B, and event B can occur before event A... This idea, called a "quantum switch," was first proposed in 2009 by another team and has since been explored both theoretically and experimentally. Previous experiments showed event A could both precede and succeed event B, but the research couldn't say that these two scenarios were happening at the same place, said Cyril Branciard, co-author of this new study and a...

The snake was spotted last week in a Woodbridge, Va. resident’s backyard, according to the department. In addition to the photos, wildlife management officials shared a video of the two-headed serpent twisting and wriggling inside a container . . .

    The human gut is lined with more than 100 million nerve cells—it’s practically a brain unto itself. And indeed, the gut actually talks to the brain, releasing hormones into the bloodstream that, over the course of about 10 minutes, tell us how hungry it is, or that we shouldn’t have eaten an entire pizza. But a new study reveals the gut has a much more direct connection to the brain through a neural circuit that allows it to transmit signals in mere seconds. The findings could lead to new treatments for obesity, eating disorders, and even depression and autism—all of...

A team of researchers in the US decided to give a group of octopuses MDMA, often referred to as ecstasy or Molly to see how it would alter their behaviour.After being dosed, the sea creatures become much more social, friendly and interested in others.It made the animals — normally anti-social creatures...

    A previously unclassified creature that lived over 500 million years ago, considered the "Holy Grail of paleontology," has finally been identified, thanks to fossil fat. The creature, known as Dickinsonia, was previously found in northwest Russia near the White Sea. It had not been classified before, until other recently found Dickinsonia fossils showed the presence of organic tissue, allowing researchers to identify molecules of cholesterol, described as "a hallmark" of animals. Brocks added: “Scientists have been fighting for more than 75 years over what Dickinsonia and other bizarre fossils of the Edicaran Biota were: giant single-celled amoeba, lichen, failed experiments...

    Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate. Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air. Worldwide efforts to make sodium-ion batteries just as functional as lithium-ion batteries have long since controlled sodium's tendency to explode, but not yet resolved how to prevent sodium-ions from "getting lost" during the first few times a battery charges and discharges. Now,...

    Cornell says Brian Wansink “committed academic misconduct,” and is leaving the university. He’s a cautionary tale in bad incentives in science. Thirteen of Wansink’s studies have now been retracted, including the six pulled from JAMA Wednesday. ...To date, 13 of his papers have been retracted. And that’s stunning given that Wansink was so highly cited and his body of work was so influential. Wansink also collected government grants, helped shape the marketing practices at food companies, and worked with the White House to influence food policy in this country.
  • The Truth About Polygraph Tests: They're Junk Science,

    City Journal ^ | Claire Berlinski
    News organizations would render a valuable service if, whenever they report that someone has taken or proposes to take a polygraph, they reminded readers (or explained to them) that polygraphs are voodoo. Junk science. They are no more reliable than a pack of Tarot cards. Polygraph evidence is inadmissible in court. There is a good reason for that. To check Brett Kavanaugh’s qualifications for the Supreme Court, Congress would do well to ask him whether he believes Frye v. United States and United States v. Scheffer were correctly decided. This would be far more illuminating (and meaningful) to anyone trying...

    Star Trek’s Spock comes from the planet Vulcan, which of course doesn’t exist. But new research might give us the next best thing—an exoplanet orbiting the real-life star that Vulcan is said to be orbiting in the Star Trek universe. In 1991, Gene Roddenberry wrote a letter to Sky & Telescope about what kind of star the planet Vulcan was likely to orbit. In that letter, he specifically picks out one such star, 40 Eridani. Later, 40 Eridani became the canon Vulcan star system featured in a handful of episodes of Star Trek: Enterprise.
