Canada to conduct world’s first Zika vaccine test on humans

A Canadian university in July 2016 said that it will conduct the world's first Zika vaccine test on humans. The vaccine that is under development will be tested on humans in the near future. Until now, vaccines have been tested on mice.

Kobinger, a doctor of microbiology and professor of medicine at the university, is overseeing the study.
•    The disease is caused by a virus transmitted primarily by Aedes mosquitoes.
•    People with Zika virus disease can have symptoms including mild fever, skin rash, conjunctivitis, muscle and joint pain, malaise or headache. These symptoms normally last for 2-7 days.
•    There is scientific consensus that Zika virus is a cause of microcephaly and Guillain-Barré syndrome. Links to other neurological complications are also being investigated.
•    The virus is capable of causing serious birth defects and has traveled quickly through Latin America.
•    There is no existing treatment or vaccine for it.

China builds World's largest radio telescope

China has finished the installation of the world's largest radio telescope, according to reports from state media. 

•    The last of the telescope's 4,450 triangular panels was fitted into the dish this weekend, ahead of the telescope's planned launch in September. 
•    The Five Hundred Meter Aperture Spherical Telescope (or FAST) is the size of 30 soccer fields, and has taken over five years and $180 million to build.
•    FAST is nearly twice as big as the next largest radio telescope — the 300-meter-wide Arecibo Observatory in Puerto Rico. 
•    One of the scientists involved in building FAST said that if it the telescope's dish was filled with wine, there would be enough to give five bottles of the stuff to each of the Earth's 7 billion inhabitants.
•    The telescope will be put to more serious uses: searching for extraterrestrial life and exotica of the Universe such as pulsars, quasars, and gravitational waves. 
•    More than 9,000 residents living within a 5 kilometer distance of FAST were relocated during the telescope's construction. 
•    Each received 12,000 yuan ($1,800) in compensation from the Chinese government.

Rare dinosaur-era bird wings found in myanmar

Scientists have discovered specimens of complete wings of tiny, prehistoric birds that were trapped in amber 100 million years ago and preserved in exquisite detail.
•    Thousands of fossil birds from the time of the dinosaurs have been uncovered in China. However, most of these fossils are flattened in the rock, even though they commonly preserve fossils.
•    The new specimens, discovered by researchers including Xing Lida from the China University of Geosciences, and Mike Benton from the University of Bristol in the UK, come from a famous amber deposit in northeastern Myanmar, which has produced thousands of exquisite specimens of insects of all shapes and sizes, as well as spiders, scorpions, lizards, and isolated feathers.
•    This is the first time that whole portions of birds have been noted.
•    The fossil wings are tiny, only two or three centimetres long, and they contain the bones of the wing, including three long fingers armed with sharp claws, for clambering about in trees, as well as the feathers, all preserved in exquisite detail.
•    The Burmese amber deposits are producing a treasure trove of remarkable early fossils, and they document a particularly active time in the evolution of life on land, the Cretaceous terrestrial revolution.
•    Flowering plants were flourishing and diversifying, and insects that fed on the leaves and nectar of the flowers were also diversifying fasts, as too were their predators, such as spiders, lizards, mammals, and birds.
•    The research was published in the journal Nature Communications.

Newly renovated and expanded Panama Canal was reopened by the Panamanian President, Juan Carlos Varela.

Newly renovated and expanded Panama Canal reopened for bigger business on 26 June 2016.
The first ship to cross the canal using the third set of locks was a modern New Panamax vessel, the Chinese-owned container ship Cosco Shipping Panama.
The 5.25 billion US dollar project was unveiled nearly two years late after construction delays, labour strife and apparent cost overruns.
The project is expected to create demand for ports to handle New Panamax ships.
•    The Panama Canal expansion project is also called as the Third Set of Locks Project.
•    The project was formally proposed by the then-Panamanian President Martín Torrijos on 24 April 2006.
•    A national referendum approved the proposal by a 76.8 percent majority on 22 October 2006.
•    The project formally began in 2007.
•    The project has built two new sets of locks, one each on the Atlantic and Pacific sides, and excavated new channels to the new locks.
•    It also widened and deepened existing channels.
•    It also raised the maximum operating water level of Gatun Lake.
•    The expansion doubled the Canal’s capacity, and has a direct impact on economies of scale and international maritime trade.
•    The project doubled the capacity of the Panama Canal by:
•    Adding a new lane of traffic allowing for a larger number of ships
(b) Increasing the width and depth of the lanes and locks allowing larger ships to pass. The new larger size of ships is called New Panamax. They are about one and a half times the previous Panamax size and can carry over twice as much cargo.
•    The Panama Canal is a man-made 48-mile waterway in Panama.
•    It connects the Atlantic Ocean with the Pacific Ocean.
•    The canal cuts across the Isthmus of Panama.
•    It is a key conduit for international maritime trade.
•    France began work on the canal in 1881, but stopped due to engineering problems and a high worker mortality rate.
•    The United States took over the project in 1904, and opened the canal on 15 August 1914.
•    The Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans.
•    Colombia, France and later the United States controlled the territory surrounding the canal during construction.
•    The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for handover to Panama.
•    In 1999, the canal was taken over by the Panamanian government. It is now managed and operated by the government-owned Panama Canal Authority.
•    The American Society of Civil Engineers has called the Panama Canal one of the seven wonders of the modern world.

Scientists have developed a new stem cell-containing bio-ink that allows 3D printing of complex living tissues

The new bio ink containing stem cells allows scientists to 3D print of living tissue which is also known as bio-printing. 
•    The ink contains two different polymer components: a natural polymer and a sacrificial synthetic polymer. 
•    The natural polymer was extracted from seaweed. 
•    It provides structural support when the cell nutrients are introduced. The synthetic polymer used in the medical industry helps the bio-ink to change its state from liquid to solid when the temperature is raised. 
•    The special bio-ink formulation has helped scientists to construct complex living 3D architectures after it was extruded from a retrofitted benchtop 3D printer, as a liquid that later transformed to a gel at 37°C. 
•    Stem cell is an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells (through mitosis) of the same type and from which certain other kinds of cell may be formed by the cellular differentiation. 
•    In the stem cell treatments new adult cells are introduced into the damaged tissue through the intervention strategy to treat the disease. 
•    These treatments have potential to change the face of curing human diseases and alleviate suffering.
