• A new study has found that hand dryers may be just spreading around bacteria in the bathroom and are not hygienic at all.
  • The study, published in the journal Applied and Environmental Microbiology, determined that hot air hand dryers spread around all the bacteria that gather in the bathroom despite the fact that they often advertise how hygienic they are
  • Toyoda Gosei unveiled a bizarre new concept Flesby II at Toyko Motor Show.
  • It has rubber airbags on the outside of the car, which move with electric power.
  • These rubber panels can even change the shape of the car, the firm says.
  • The car is still in the concept phase, but Toyoda Gosei estimates it could come to life around the year 2030.
  • The inside of the ultra-compact car is lined with ‘softly-textured material,’ according to the firm.
  • It also contains LED lighting, to create a ‘soothing space.’ With airbags on the outside, the car aims to make driving safer for both the rider and pedestrians, by absorbing the impact to minimize damage in a collision.

  • A Dutch startup is training crows to pick up cigarette butts from city streets. The crows will be rewarded with food for every butt they deliver.
  • More than 4.5 trillion cigarette butts thrown on the ground around the world each year.
  • 98 % of these butts are made from plastics like cellulose acetate that take more than 10 years to break down.
  • The cleanup of cigarette butts is difficult as they are dispersed across urban areas and can be moved into difficult to reach areas by wind and rain.
  • But a Dutch startup has the answer to fix the problem. And the answer is crows.
  • Ruben van der Vleuten and Bob Spikman, two designers have established the startup called Crowded Cities and their first product, is the Crowbar.
  • According to researchers, crows have an amazing memory and communicate very effectively.

What happened when NASA sent one identical twin brother to space for a year!

NASA had sent one identical twin brother for a year after, to assess how the human body changes as a result of space travel using Scott Kelly and his twin brother Mark Kelly as subjects.

After spending a year in space, he was 2 inches taller.

Scott spent 340 days aboard the International Space Station, Mark stayed on Earth, giving NASA the rare opportunity to compare two identical sets of DNA.

Scott and Mark have the same genes, but Scott's year in space appears to have strongly affected the way those genes are expressed.

Researchers knew that taking humans for a short journey outside Earth's protective atmosphere has plenty of effects on the human body, like stretching your spine, shrinking your muscles, and messing up your sleep cycle - but the effects of long-term exposure to space have been less well-known.

Here are some of the most interesting results so far:

- Scott's telomeres got longer, then shrunk back to normal.
- Scott's genes showed both increased and decreased levels of methylation, a process that results in genes getting turned on and off.
- Researchers noted differences between Scott's and Mark's gut bacteria.
- By sequencing the RNA in the twins' white blood cells, researchers found more than 200,000 RNA molecules that were expressed differently between the brothers. 

Space Graveyard on Earth

There is a dumping ground for retired spacecraft on earth.

Most fallen large satellites, space stations, and other space objects end up in Point Nemo, an area miles off the southeast coast of New Zealand. It’s also referred to as the most remote place on Earth.

"It's in the Pacific Ocean and is pretty much the farthest place from any human civilization you can find," NASA said.

This graveyard also called the Oceanic Pole of Inaccessibility or the South Pacific Ocean Uninhabited Area is 1,450 miles away from land and civilization and is a tomb for hundreds of retired satellites.

It stretches 3,000 kilometres from north to south, by about 5,000 kilometres from west to east. The depths are cold, dark and house little sea life. Mostly sponges, whales, viperfish and octopi.

Deposing of the smaller satellites is easy, Heat from air friction as it catapults toward Earth burns the satellite to dust before it hits the ocean. Larger satellites in a low orbit is a more significant problem as they will likely not burn completely.

Between 1971 and mid-2016, global space agencies dumped an estimated 260 spacecraft debris into Point Nemo.

Meet the first-ever robot citizen - a humanoid named Sophia that once said it would 'destroy humans'

Sophia the robot is the first robot in history to be granted full citizenship of a country.

Sophia the robot might not have a heart or brain, but it does have Saudi Arabian citizenship.
As of October 25, Sophia is the first robot in history to be a full citizen of a country.

Sophia was developed by Hanson Robotics, led by AI developer David Hanson. It spoke at this year's Future Investment Initiative, held in the Saudi Arabian capital of Riyadh.

Sophia once said it would "destroy humans," but this time around the robot spoke about its desire to live peaceably among humans.

‘Magic mushrooms’ may help ‘reset’ depressive brains

“Magic mushrooms can 'reboot' brain to treat depression,” reports the Daily Telegraph.

The news is based on a small UK study that looked at the effects of psilocybin, a chemical found in magic mushrooms, on patients with severe depression.
All 19 patients said their depression improved immediately after taking psilocybin and almost half said they still felt the benefits 5 weeks later.

The effects of psilocybin were measured using a functional MRI scan, an advanced MRI machine that measures blood flow in the brain.

The researchers believe psilocybin helps to change how networks of nerves communicate in the brain, which might disrupt negative thought patterns. A fall in blood flow suggests that brain activity has reduced.
