Shuaiwen Leon Song, a researcher at the Pacific Northwest National Laboratory, studies high performance computing with the aim of making computers faster, smaller and more energy efficient.

The leap from supercomputers to video games started when Song asked if a hardware known as “3D stacked memory” could perform something it was never planned to execute: help deliver 3D graphics. 3D delivering has advanced science with models, visualizations and virtual reality- the material of video games.

Song and team worked to develop a new architecture for 3D stacked memory which increases 3D delivering speeds up to 65%.

A normal graphics card uses a GPU (graphics processing unit) to make images from the memory stored data. 3D stacked memory has an additional logic layer which enables the memory to do some processing too -- hence called "processing in memory." This reduces the data traveling from memory to GPU cores. And, less traffic means faster speeds.

The final step in delivering is known as anisotropic filtering. It creates the most traffic. They moved anisotropic filtering to the first step to achieve greatest performance boost. Song tested this architecture on renowned games like Half-life 2 and Doom 3.

The Road Has Got its Street Hockey

22 Sep 17

Street Hockey is also known as dek hockey, ball hockey and road hockey. The sport is a variation of ice hockey. The sport is played outdoors on foot or can be played using inline or roller skates. The ball and puck of street hockey are designed according to the non-ice surfaces. It is played by shooting the ball or puck into the opposing team’s net.

Street hockey is always played on an outdoor surface in its pure form. It is very often played on a street, parking lot, tennis court or the asphalt surface. It was believed that street hockey started when the roads were paved in the wealthy parts of North America. It was around 20th century. Street Hockey was then spread south to the United States. Children, teenagers and even all ice hockey players work on their skills by playing street hockey. They practice it often alone in driveways or out in the street in front of their houses.

Mary Fields Who Protected Wild West Stagecoaches

22 Sep 17

The Stagecoach Mary was the daring black pioneer who protected Wild West Stagecoaches. She was the first African-American woman mail carrier. The story of her life becomes clearer after the end of Civil War, when she was released from slavery.

Fields headed north to friendlier territory just like her former slaves did. She seems to have gone up the Mississippi River while working on riverboats and also worked as servants and laundress for families all along her way. It is not clear that how Mary found Ursuline Convent of the Sacred Heart in Toledo, Ohio. Dee Garceau-Hagen who a historian is told that one nun in the Convent remembered Mary’s anger when anyone disturbed her beautifully kept grounds.

In the year 1895, she received a contact from the postal service to become a star route carrier. She carried mail using stagecoach donated by Mother Amadeus. Her responsibility was to protect the mail on her way from thieves and bandits and to deliver mail. She performed this role for eight years.

As he was a great individual, The Aston Villa Supporters Trust has raised a good amount of money to clean up the grave of Mr. McGregor. Therefore the grave of the founder of the Football League has been rededicated. It was he who gave a league and a proper structure team format. The poor condition of the grave was brought into attention by Peter Lupson, a football author and a historian. Earlier in 2009 a statue of Mr McGregor was erected outside Villa Park. It is also proposed to engrave the sentence “Founder of the football league and chairman of Aston Villa FC” on his grave as he is valued as the father of all football leagues. It's a very important recognition, not just for Villa but for football in general across the world. This great person Mr. William, who died in 1911 at the age of 65, is going to be honoured in a grand ceremony and to be remembered forever for his great contribution.

Ancient Defense Mechanism is No Longer to Fight Viruses

21 Sep 17

It has never been easy for the living creatures like plants, insects, animals and the humans to survive with changing environment and elements that create threat to them. There is ancient defence mechanism in plants and insects that helps them to fight with various kinds of viruses which is encoded in the DNA.

It was considered by the scientists that the same kind of mechanism is present in humans that enable them to fight with viruses; however, researchers have come to a conclusion that this unique mechanism has come towards a big loss with time. There are two types of Argonaute proteins found in the organisms that are very important for the research namely: AGO1 and AGO2. It is essential that these proteins must evolve fast, as the viruses have a rapid adapting capability.

It was found during research that as AGO2 proteins indeed evolved much faster than that of AGO1 counterparts; however the speed was not the same in vertebrates. Over the time the capacity and speed of these Argonaute proteins have decreased. It is also true that with the developing of a secondary immune system in which antibodies, interferons, and T-cells are there to fight viruses; these proteins have lost their significance. Due to this it is found that RNA interference is more effective in insects than humans. We now depend upon other antibodies.
