Researchers in the US have developed a new drug that can be delivered directly into the eye via an eye dropper to shrink down and dissolve cataracts - the leading cause of blindness in humans.  While the effects have yet to be tested on humans, the team from the University of California, San Diego hopes to replicate the findings in clinical trials and offer an alternative to the only treatment that’s currently available to cataract patients - painful and often prohibitively expensive surgery.  Affecting tens of millions of people worldwide, cataracts cause the lens of the eye to become progressively cloudy, and when left untreated, can lead to total blindness. This occurs when the structure of the crystalline proteins that make up the lens in our eyes deteriorates, causing the damaged or disorganized proteins to clump and form a milky blue or brown layer. While cataracts cannot spread from one eye to the other, they can occur independently in   ...

An eerily life-like robot has been turning heads at the World Robot Exhibition in Beijing   last  week. Named Android Geminoid F, the robot has a legion of fans, with some even describing her as 'sexy'. She is designed act like a human with rubber 'skin' and a woman's face - but can't walk and has to be wheeled around. The robot was created by Hiroshi Ishiguro Laboratory at Osaka University who plan on creating a better model in the future. The 5ft 6 inch android is capable of eye movements, response to eye-to-eye contact and can recognize body language.  Our final goal is creating some artificial intelligence by using this robot,' Kohei Ogawa, assistant professor said.  'Most voice recognition systems do not work, especially in this kind of noisy environment. 'In the future we're going to create some perfect AI system by using this robot. The current version of Geminoid F cost $108,600 (£72,000), which Ishiguro ho...

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...

Life in zero gravity is much different than life on Earth.  We   get to enjoy both the taste and the smell of drinking hot coffee from a mug. Astronauts on the International Space Station don’t have this luxury and must drink their coffee using a straw that draws the liquid out of a closed container. This diminished coffee experience may change for the astronauts thanks to a new 3D-printedcup designed to help NASA study the behavior of fluids in micro-gravity. The idea for studying coffee and other liquids consumed in space surfaced after Italian European Space Agency astronaut Samantha Cristoforetti received an espresso machine. The opportunity to study capillary flow, liquid containment, and low-gravity fluid dynamics was too great to pass up. A team of researchers was assembled by NASA, and they went to work designing six different transparent polymer cups for use on the space station.  Five of the cups hold 150ml, while the sixth, a smaller 60ml...

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 ...

According  to  a  new  research   ,regular  brisk  walking   is  a   more  effective   method   for  weight  loss  than   going  to  the  Gym. e="font-size: x-large;"> A study by the London School of Economics found that those who engaged in “regular, brisk walking” for longer than half an hour had lower Body Mass Indexes (BMI) and smaller waists than those who did other exercise such as going the gym or playing football or rugby. The results were particularly true for women, people over 50 and those on low incomes. Dr Grace Lordan, who led the research said: “The results thus provide an argument for a campaign to promote walking… Given the obesity epidemic and the fact that a large proportion of people are inactive, recommending that people walk briskly more often is a cheap and easy policy option.” ...
