SPACE  SUITS  are    wear  by  the  Astronauts    who  go  into   space.It   protects  them .Earlier   Astronauts   had  only  one  type  of space suits,but  today  they  wear  different  type  of  space suits  for  different  activities.For    working   in   a  space station there   is  a  light    weight   space  suite,a  special  space  suit   for  to  and  fro  flight .For   walking  outside  the   spaceship   ,air  sealed  space suit  is  used.The   space suit  for  walking  in  the  space  comprise  many  many  layers  of  plastic   and textiles  .Coolants  run  through  the  tubes   in  the  inner  most  layer,which  protect  the  astronauts  against  over heating   during  strenuous   work.A   middle  layer    maintains  the   inside   pressure   against  the&nbsp ; extreme  low  pressure  of  the  empty  space.Space  suits    are   very   important  with out   the  space  suit   the  air  would   escape  from  the  lungs  of   the  astronauts ,  an

Our genes determine our physical characteristics such as height, weight, and skin color. These genes sometimes experience mutations that alter the physical traits observed. Gene mutations are changes that occur in the segments of DNA that compose a gene. These changes can be inherited from our parents through sexual reproduction or acquired throughout our lifetime. While some mutations can lead to diseases or death, others may have no negative impact on or may even benefit an individual.  Other mutations can produce traits that are  cute.  Some  cute features caused by gene mutations. Dimples.   Dimples are a genetic trait that causes the skin and muscles to form indentations in the cheeks. Dimples can occur in either one or both cheeks. Dimples are typically an inherited trait passed down from parents to their children. The mutated genes that cause dimples are found within the sex cells of each parent and are inherited by the offspring wh

Swiss engineers have invented a pacemaker based on an clockwork wristwatch which is powered by the motion of the heart. The prototype, which has been successfully tested in pigs, could mean that patients no longer have to undergo repeat surgery when the batteries in their device run out. The invention, presented to the European Society of Cardiology Congress in Barcelona, is based on the concept behind a self-winding wristwatch. Currently pacemakers, which are used to help the heart beat more regularly, need to be replaced on average every seven years, when batteries fail More than 40,000 people a year are fitted with pacemakers in England. The devices are used for patients with unusually fast, slow or irregular heart rhythms. The new model, stitched directly on to the heart, is based on the concept of automatic clockwork developed by Swiss watchmakers in 1777 and generates electrical current using the movement of heart muscle.  Automatic watches work beca

Japanese  mobile  phone  giant   ' Kyocera '  has  created   a phone  that  can  be  washed   with  soap  without  any  damage  to  the  hand set .Expert   in   Japan  announced  they  have created  the  device  which   allows  users  to  sanitize  their  phone  -riding  it  of  bugs  and  muck . The  average  phone   is  thought  to  be  covered  in  bacteria   picked   from  people's  hand  and  clothing. Test  have  revealed  that  most even   have  more  bacteria   than  the  average  toilet . Now ,   Kyocera   have   created  a  device  that  can  be   cleaned. The  phone  named  'Digno Rafre'    can  be   cleaned  as  thoroughly   as  a  piece  of  cloth  and  is   to  be  released    next  week   Japan.   The    developers    have   remained  silent   on  the  secrets  how  it   keeps  working  while  wet .They  have  only   announced   that  the  phone  has  no  speaker  and  instead  transmit  sound  through  "connective  tissue&qu

Use your best judgement on this, but if in doubt, take your jewelry off. Keep reading to learn about the importance of where you store your j

THE   brain  is  made  up  of  two  halves.Different    areas   of  the brain  have  different   functions.All   nerve  cells in  the  brain ,  about  100.billion  of  them   are  connected  to  one  another  and  transmit  information.This  network  of  nerve  cells  is  expanded  through  learning  and  training.  Our  brain  controls  our  actions ,   regulates  our  sleep and  allows  us to  feel  sensations  like  pain  and  joy.If  it is  damaged ,due  to  stroke  or some  other reason ,one has  to  relearn  a  lot  of  things  like speaking, walking,or eating. NERVE  CELLS  TRANSMIT  SIGNALS .This   process  is  quite   complicated.Like  other  cells ,nerve  cells  also  have   a  cell  body  with  a  nucleus .These  are  fine   extended   branches   known  as  dendrites  and  a  long  tail   called  axon   on  the  body   of   the  nerve  cells.Axon    in  the  brain   are  smaller   than  1mm,  whereas   in  the  spinal  cord they  can  be  as  long   as 

THE  EARTH  IS  ROUND  ,IT  has  been   known  for  more  than  2000   years,but  we  were  able  to   actually   see  this   much  later  only  when   we  flew  into   space .The  Earth  is  made  up  of rocks,   soils  ,and  water.It  is surrounded   by   an  air  cover   called  the  atmosphere. INTERNAL    STRUCTURE   OF  THE  EARTH .-Like   an  Onion  Earth  has  several  layers.The  outer  most  layer,  the  Earth's  crust,has   an  average   depth  of  40  k.m.As   compared  with  the  diameter   of  the  Earth  ,which  is  around,12,700 km,the  Earth's  crust  is  very  small.It  is  primarily  made   up  of   solid  rocks.Below  the  crust   is  the  mantle   reaching  to  a  depth  of  about   2900km.Due  to  the  heat   inside  the   earth   ,the  mantle  consist  of  solid  and   molten  rocks..Below  the  mantle  is  core,made   up  of   Iron   and  Nickle.The  deeper  one  travels  inside  the  Earth  ,the  hotter  it  is .The   temperature   in  t
