Drones Can Be Hacked
A team of
researchers at the University of Texas at Austin won a $1,000 bet with the
Department of Homeland Security by hacking into an airborne drone and wresting
control from the pilot.
The
researchers, headed by Dr. Todd E. Humphreys, got control of the drone by
overloading it with false signals that were precisely matched up with authentic
satellite signals. Once that happened, the drone ignored the original pilot,
instead obeying the hackers’ every command.

Tea is Life : Strange Tea Facts
Tea was accidentally invented in
2737 BC when Chinese Emperor Shen Nung spotted some tea leaves blew into a pot
of boiling water and produced a pleasing aroma. 1.42 million pounds of tea are
consumed per day in the United States. An average of three billion cups of tea
are consumed daily worldwide.
Today tea is more popular than ever, and is
the second most consumed drink in the world, losing only to water. Scientific
studies are coming out regularly which are showing the health benefits of tea,
which perfectly fits the idea of people trying to live more healthy lives. Tea
is no longer expensive to buy, and is considered by some to be not just a
drink, but a part of their lives
Quotation :
Tea is a cup of life.
