2016 Chemistry Nobel Prize.

 1983- Jean-Pierre , Fr. succeeded in linking two ring-shaped molecules together to form a chain,  catenane. Normally, molecules are joined by strong covalent bonds in which the atoms share electrons, but in the chain they were instead linked by a freer mechanical bond. For a machine to be able to perform a task it must consist of parts that can move relative to each other. This satisfied the requirement.

 1991- Frasr Stoddart,Scot. developed a rotaxane. He developed a molecular axle and a molecular computer chip.

1999- Bernard Feringa, Netherland, developed a molecular motor; Using these, he has rotated a glass cylinder that is 10,000 times bigger than the motor. He  has also designed a nanocar.


Goat Milk Promises Cheap Cancer Treatments:

 New Zealand Scientists

“Genetically modified goat milk has been used to create a new biotechnology process that promises cheaper anti-cancer drugs, New Zealand scientists said Wednesday.”

Milking goats have been used to produce mono-clonal antibodies (MCA) in their milk, which are specifically used as human anti-cancer treatments, in a process developed by the government’s AgResearch institute.”

“Once a drug comes off patent, anyone can produce it, but the price is ultimately regulated by the cost of production and these drugs are typically very expensive,” Professor Peter Shepherd, leader of the University of Auckland team, said in a statement.

Kakapo Genome Sequencing a Whole Lot of Help

A group of kakapo will have their genomes sequenced in the hope it will improve the birds’ genetic diversity. There are only 125 kakapo left and every one of them will have their genetic make-up studied as part of the project.

This is the first time that genome sequencing of a whole population of one animal has taken place.

Scientists say analysing the data will help them to save the flightless kakapo from extinction by providing information on fertility and susceptibility to disease. It will also show which birds are closely related, so that inbreeding can be prevented.





4. Re directing Lightening Flashes.

A group led by Andre Mysycowicz  of ENSTA Paris Tech. France, using
LASERS, developing trillions of Watts just for a few femtoseconds
could divert lightning flashes . When a powerful beam is directed to a
cloud it ionises the air molecules. The electron discharge  from a
cloud follow this trail.  Ref. New Scientist 10/4/2012.National
Geographic of 16/4/2008 also reported an experiment of this nature
conducted in Mexico.

Re directing a Flash can protect people and property.

 

  •  4.    It may help to live longer.

 

A drug called RAPAMYCIN has been discovered that may extend your life. It has been tried out in laboratory mice and soon the human trials will start. The researchers were the health Centre of the University of Texas

1. Chemo sensory Perception

 It seems temperature  at which you take food has an effect to the taste.

Sournes ;-  Increases with temperature.

Bitterness decreases with temperature.

Sweetnes;- unaffected by temperature

 2. Oldest Biological Clock.

Scientists believe that the oldest Bio-clock is a substance known as PRX.

Peroxide redoxin

This substance seem to be present from the ancient bacteria up  to the  most advanced living things.
