P. aeruginosa, is one of the strains of bacteria responsible for urinary tract and other types of infections in people. The researchers chose it to study as a means of learning more about the ways bacteria that actually infect people might behave in a zero-gravity environment. Such research is important as space agencies contemplate longer missions at much farther distances.In this latest effort, the researchers added the bacteria to several containers of simulated urine that were put aboard one of the last Shuttle missions—each with a different mix of nutrients and amount of bacteria. Astronauts aboard the shuttle were able to monitor bacterial growth as were researchers on the team after the samples were brought back home.In analyzing the results, the researchers found that after 72 hours when fed an abundance of nutrients P. aeruginosa concentrations in space were nearly identical to those of Earth-bound samples. But, when the nutrients were greatly reduced, the researchers found that the bacteria in space kept up the same pace—concentrations of the bacteria were nearly the same as those that had been given a lot of nutrients. Those bacteria in the lab back on Earth, on the other hand, when fed the same small amount, showed far less growth. The study indicates that scientists designing systems to protect future astronauts against bacterial infections, headed for places like Mars, may have their hands full. P. aeruginosais is a type of bacteria that could very easily infect human waste processing systems. Also getting rid of such colonies would be difficult as they are notoriously difficult to eradicate here on Earth. Now that it’s known they can thrive with even fewer available nutrients, the problem becomes even harder to solve.

In their paper published in BMC Microbiology, the researchers describe an experiment they conducted aboard NASA Shuttle Atlantis that showed that Pseudomonas aeruginosa, a very common type of bacteria, grows more dense cultures when in space than it does on Earth when available nutrients are restricted.
Everyone, at least for once, have come across the works of William Shakespeare or have in the least heard about him. Also, there are many, who are familiar with the name of Shakespeare, but might not have got a chance to witness his work through a book, a play or a movie.To introduce such people to the world of the greatest dramatist of all time and to commemorate his 400th death anniversary, six movies from different internationally acclaimed director were recently screened in the CD Deshmukh Auditorium at India International Centre (IIC) in the national Capital. Also Read – Add new books to your shelfThe film screening ‘A Date with Shakespeare’ was the part of IIC annual festival ‘The IIC Experience-2016’.The films screened included Macbeth, King Lear, All Night Long, Hamlet, Throne of Blood and Othello, which were directed by Roman Polanski, Peter Brook, Basil Dearden, Grigori Kozintsev and Iosef Shapiro, Akira Kurosawa and Orson Welles respectively. Each film was critically acclaimed at its time and had bagged many awards. Othello had received Grand Prize of the Festival at Cannes Film Festival in 1952.

While some portay the plays in traditional manner, others transport the action to other periods and setting. For example, Basil Dearden’s All Night Long, translate ‘Othello’ to the smoky world of sixties London jazz clubs, showing just how current and relatable the themes of Shakespeare’s work continue to be.King Lear (1971) is a noted tragedy in black and white, which delivered the saga of the aging, self-deluding regent in a evocative manner. Whereas Othello (1951) rearrange the order of the tragedy and starts with the funeral of the protagonist, thereby turning it into a film noir as the murder investigation takes place to find out the cause of their deaths. The movie concluded the film festival.William Shakespeare’s plays remains highly popular and are constantly studied, performed and reinterpreted in diverse cultural and political context throughout the world. Around 400 films based on Shakespeare have been made and shared online. Shakespeare has an annual commercial value of over $ 1 billion with over 5,000 individual stage production each year.
