A   Company  in  France  has  developed  a  new  ,smart  umbrella  that ,  when  paired  with  a smart  phone  app,can  not  only  predict  the  weather   but  also  send you   a   notification,if  you  leave  it  behind . The  name  given  to  it  is  'Oombrella'.It  is fitted  with  a  capsule  having  sensors     for  air pressure,humidity,temperature    and  light . This   set  up  allows  umbrella to  tell  whether  or  not  rain  in  next   fifteen  minutes,notifying   the  user  via  an  app.It  can  also  record  weather data   and   can  held the  camera  on...

Two  academics have  shocked  the  world   of  Mathematics  by  discovering  a  pattern  in  Prime  numbers. Primes  -  numbers  greater  than  1  that  are  divisible   only  by    themselves   and  1  - are  considered   the  'building  blocks '  of   mathematics,  because  every  number  is either  a  prime  or  can  be  built  by  multiplying  prime  numbers  together  -84  ,  for  example ,   is  2x2x3x7. The  properties  of  prime  numbers  have  baffled  number  theorists  for  centuries ,  but   mathematicians   have  felt  safe   working  on  the  assumption  they could  treat  prime...

Soon  ,you  will  be  able   to  log  into  your  smart phone  with  sweeping  gestures  or  doodling  by  using  one  or  more  fingers. Researchers   from  Rutgers University  in  the  US  have  performed  the  first  study  of  free-form   gestures   passwords  for  smart phones  in  the  field .Free-  form  gestures passwords   allow  people  to  draw a password    of  any  shape  with  any  number  of  fingers,researchers  said. The  results  show  that  free-form  gesture  passwords  are  a serious  alternative   to  text or  other  log-in  methods  ,especially  for  mobile  devices ,  they  said.Free...

New research suggests that a lack of remaining domain names with easy to remember – and consequently valuable – word combinations is restricting Internet growth, with an untapped demand of as much as 25% of all current domains being held back. The study’s author contends that the findings show ICANN’s release of new top level domains could prove a wise policy.  As the digital age dawned, pioneers successfully snapped up broad swathes of the most popular and memorable domain names, such as nouns, places and combinations thereof – claiming valuable ‘virtual real estate’ under the top level domains such as dot-com, dot-co-dot-UK and so on. Now, the first research to try and define current demand for Internet domain names suggests that the drying up of intuitive and familiar word combinations has seen domain registration drop far below the expected appetite, given the extent to which we now live online, with new entrepreneurs struggling to find “their slice” o...

For the first time, scientists have identified the activity of a metabolic enzyme found in the batteries of human skin cells declines with age, an advance that may lead to powerful anti-aging treatments.  A Newcastle University study, published online in the Journal of Investigative Dermatology, has found that the activity of mitochondrial complex II significantly decreases in older skin.  This discovery brings experts a step closer to developing powerful anti-aging treatments and cosmetic products which may be tailored to counteract the decline in the enzyme's  activity levels, researchers said. The findings may also lead to a greater understanding of how other organs in the body age, which could pave the way for drug developments in a number of age-related diseases, including cancer.  As our bodies age, we see that the batteries in our cells run down, known as decreased bio-energy, and harmful free radicals increase," said Mark Birch-Machin, Prof...

Scientists developed the first implantable artificial kidney in the world. The artificial kidney contains a microchip filter and living kidney calls that can run using the patient's heart. The bio-hybrid kidney mimics the real organ by removing salt, water and waste products to keep patients from relying on dialysis. At the heart of the artificial kidney lies the microchip called silicon nanotechnology. Each artificial kidney contains 15 microchips in layers that are used as filters and a support system wherein the living cells will be placed. Dr. William H. Fissell IV explained that kidney cells can be grown in a laboratory dish and nurtured into a bioreactor of living cells. This will then become the 'Santa Claus' membrane that can distinguish 'naughty' and 'nice' chemicals.   they can reabsorb the nutrients your body needs and discard the wastes your body desperately wants to get rid of," said Fissell, an associate professor of ...

A new blood test that detects five different forms of cancer is one step closer to becoming a reality and could save millions of lives around the world. The team of scientists developing the new diagnostic tool have branded their discovery of a 'striking DNA signature' in five forms of the disease, an 'important step'. The signature occurs in colon, lung, breast, stomach and endometrial cancers, researchers at the National Human Genome Research Institute found. When tumors develop in any of these areas, one specific gene - known as' ZNF154 '- changes its chemical signature. It raises hopes that a simple blood test to diagnose these, and other forms of the disease, may become a reality in the near future. Researchers found when a person was suffering cancer, higher amounts of methylation occurred - a process where a gene is switched 'off'. They describe methylation as controlling the expression of genes 'like a dimmer on...
