Astronauts are covered with 13 layer of various clothes and fibres. When they are in space station like ISS, they don't wear any special suit but when they have to do some repairs and changing in the artificial satellites they have to wear a 13 layered suit with a bulky pack on back. So, my question is , if they have itching anywhere on their body in the spacesuit, then how they scratch them ? If you have any suggestions please comment down below and if you don't have any suggest, share it to your friends on your social accounts.
Fontanelle Fontanelles are soft spots on a baby's head which, during birth, enable the bony plates of the skull to flex, allowing the child's head to pass through the birth canal. The sphenoidal and posterior fontanelles close during the first few months after birth. Sphenoidal and posterior fontanelles are found just above the ear and behind the ear representatively . The ossification of the bones of the skull causes the anterior fontanelle to close over by 9 to 18 months. The term "fontanelle" is used to describe the resulting "soft spots". The relative positions of the bones continue to change during the life of the adult (though less rapidly), which can provide useful information inforensics and archaeology. In old age, cranial sutures may ossify (turn to bone) completely . The fusion of skull's bone at birth is known asCraniosynostosis . This is the amazing fact of your skull. This process is also seen in other animals like dogs and chimpanzee . Thank …
A breakthrough in quantum dot research by scientists at Los Alamos National Laboratory paved the way for windows that double as solar panels.Quantum dots - nano-crystals made of a semiconductor - were embedded in a transparent polymer in order to capture the sun's energy and harvest it as power.
Smart contact lenses
A smart contact lens that can monitor the glucose levels of diabetes sufferers was developed by Google in January.Coming out of the company's Google X skunk works division, best known for developing Google Glass, the contact lenses use chips and sensors the size of glitter to offer an early warning to the wearer by analysing tears.
Each thud of a hiker’s heel releases enough energy to illuminate a light bulb. Rather than waste that power, Matt Stanton, an engineer and avid backpacker, created a shoe insole that stores it as electricity.
To save more lives, a group of veterans, scientists, and engineers known as RevMedx has created …
Button - Buttons were made from seashell and were used in the Indus Valley Civilization (Now India and Pakistan ) for ornamental purposes by 2000 BCE. Buttons were carved into geometric shapes and had holes pierced into them so that they could be attached to clothing by using a thread. Ruler - Rulers were made from Ivory and used by the Indus Valley Civilization in 1500 BCE. The ruler was calibrated to about 1/16 of an inch which is less than 2 millimetres. The weights and measures of the Indus civilization also reached Persia and Central Asia, where they were further modified.Stirrup - The earliest evidence of the stirrup was a toe loop that held the big toe and was used in India late in the second century BC. This ancient foot support consisted of a looped rope for the big toe which was at the bottom of a saddle made of fiber or leather.Stepwell - The earliest stepwells most likely date to about 550 AD, but the most famous were built in medieval times. It is estimated that over 3,00…
