    The Eastern Slovakia Museum in Kosice has presented two unique bronze helmets from the late Bronze Age. A mushroom picker found them last year near the village of Trhoviste in Michalovce county. The finder brought the objects to the museum in January of this year. The museum's archaeologist Dárius Gasaj informed the Regional Monument's Board. "This precious finding consists of two Bronze helmets, partly stuck to each other. There were also two pairs of protective cheek pads and two spiral arm guards," said Róbert Pollák, director of the museum, as quoted by the SITA newswire. The finder wishes to remain...

    The bullae were used in ancient times for the sealing of letters and scrolls written on papyrus. If a letter arrived with a broken bulla, it meant it had been opened. Unfortunately, those letters and scrolls did not survive through the 2,200 years that have passed, only the seals remained, to tell the story of the archive. Dr. Donald Zvi Ariel of the Israel Antiquities Authority, one of the world's leading experts on bullae, examined a group of 300 bullae and identified on the seal impressions figures of Greek gods such as Athena, Apollo and Aphrodite, as well as cornucopia,...

    Do you see an old woman or a young woman? They are both trapped in this famous optical illusion that first appeared on an 1888 German postcard and was later adapted by British cartoonist William Ely Hill, who published it in a humor magazine in 1915 with the title "My Wife and My Mother-in-Law." Using Amazon's Mechanical Turk, an online crowdsourcing platform, researchers showed the illusion for half a second to 393 U.S. participants between the ages of 18 and 68. They were then asked if they saw an animal or a person and, if they said a person, what...

    A section of the San Andreas Fault on the Carrizo Plain in California. Image: Doc Searls/Flickr The detection of strange, unpredicted behavior deep below the surface near the San Andreas and San Jacinto faults suggests scientists have an incomplete understanding of the processes responsible for earthquakes in the region. Over the past four decades, geoscientists have recorded thousands of small earthquakes in California’s San Bernardino basin near the San Andreas and San Jacinto faults. New research published in Geophysical Research Letters suggests many of these quakes, some of which occur at depths between 6 and 12 miles (10 and 20 kilometers),...

    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 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 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...
