Discovery of new human kind of species in China

       Scientists reported on Friday that a gigantic fossilized skull dating back at least 140,000 years has been identified as a new species of ancient human, a discovery that could redefine how — and even where — our species, Homo sapiens, originated.      The skull of an adult guy with a large brain, gigantic brow ridges, deep-set eyes, and a bulbous nose was discovered. After a labourer discovered it at a building site in China, it had been hidden in an abandoned well for 85 years.      The new species was given the name Homo longi, and the nickname "Dragon Man" was given to it after the Dragon River region of northeast China, where the skull was discovered.      According to the researchers, Homo longi, not Neanderthals, was the most closely linked extinct human species to our own. If validated, it would affect how scientists see Homo sapiens' origins, which have been built up over time through fossil finds and ancien...

Is there dirty laundry floating about in space? Tide and NASA team together to take on the cleaning challenge

-

What is the best way for astronauts to do laundry in space? They aren't.

    They wear their underwear, exercise clothing, and anything else they have until they can no longer stand the filth and stench, at which point they discard it.

    NASA hopes to change that — if not on the International Space Station, then on the moon and Mars — and stop tossing away heaps of soiled garments every year, stuffing them in the garbage and letting them burn up in the atmosphere on rejected cargo ships. As a result, it's collaborating with Procter & Gamble Co. to figure out how to launder astronauts' garments in space so that they may be reused for months or even years, much like on Earth.

    The Cincinnati-based firm announced on Tuesday that it will send two Tide detergent and stain-removal experiments to the International Space Station later this year and next year, as part of the galactic fight against filthy and sweaty clothing.

    It's a significant issue, especially as the United States and other countries consider establishing outposts on the moon and Mars.

    There are other health — and ick — considerations.

    To prevent the muscular and bone thinning consequences of weightlessness, astronauts on the International Space Station exercise for two hours every day, swiftly sweating, smelling, and stiffening their training clothes. According to Leland Melvin, a former NASA astronaut and NFL player, their T-shirts, shorts, and socks are so filthy that they go through a pair every week.

    “After that, they're classified as toxic,” said Melvin, the project's spokesman. “They like to live on their own. All that sweat has made them stiff.”

    While NASA as well as other space station partners have investigated special antimicrobial clothing to extend wear, this is not a long-term answer.

    In its first experiment, P&G will launch a space-specific detergent in December to test how enzymes and other components react to six months of weightlessness. Then, in May, astronauts will be given stain-removal pens and wipe to test.

    At the same time, P&G is working on a washer-dryer combination that could be used on the moon or possibly Mars and would use very little water and detergent. A contraption like this could also be useful in desert areas on Earth.

    One of the major architectural issues is that the washing water would have to be reclaimed for drinking and cooking, similar to how urine and perspiration are recycled on the space station now.

    Melvin explained, “The best answers come from the most diverse teams, and how varied can you get than Tide and NASA?”

     On Thursday, about a month after we witnessed the uncommon phenomena of a total lunar eclipse coupled with a Supermoon and Bloodmoon in the night sky, Earth's natural satellite will appear brighter and bigger than before. The astronomical event is noteworthy for two reasons: first, it is a Strawberry Moon, and second, it is a late Supermoon. Supermoon      The Strawberry Moon is the last Full Moon of spring and the first Full Moon of summer. On June 21, the Northern Hemisphere's summer season began with the Summer Solstice, the year's longest day.      On Thursday, the Moon will appear larger than on other days as it approaches Earth in its orbit, and it will likely be visible for three days in a row. WHEN WILL INDIA BE ABLE TO SEE THE STRAWBERRY MOON?   In India, the Strawberry Moon will be visible until 12.10 a.m., when it will reach its brightest point. The moon will not be seen until it climbs beyond the horizon in the evening a...

Jagame Thanthiram Movie Overview: Dhanush, Kartik Subbaraj

    V icky, a software testing lead, begins by saying, “In IT businesses, they have a yearly group discussion.” We transition to a conference in London, where a group of techies are gathered around a table, staring at a white man who is pointing to a whiteboard that reads, "Q1 Appraisal Group Discussion." “A Tamil Nadu gangster". Vicky reveals that his advancement and pay raise are contingent on his ability to speak about the worst gangster they know. Suruli is mentioned by Vicky. Returning to Madurai, Vicky invites Suruli to join him in London to help a prominent English gangster take on another Tamil gangster.     This is the story of how a small-time Madurai thug became the right-hand man of a white supremacist. Jagame Thanthiram is a moderately entertaining affair if you're willing to fly alongside the film in such huge leaps of post-modern preposterousness.
