I try to stop the climbing death toll on this station, while getting high, mostly getting high though.

In space, water becomes a spherical ball, hovering in the air. Plants grow sideways. Humans lose muscle mass. Without earth #39;s gravity things behave...well, differently. Such is lifeand science...

Russia develops manned space program to replace ISS

Posted: at 2:51 am

Russia is developing a national program of manned space explorations which will replace the International Space Station (ISS) program after 2020, the Russian Federal Space Agency, Roscosmos, said Thursday.

"The development of the national strategy of manned spaceflight is underway now. Along with the Russian Academy of Sciences and the industrial sector we are preparing a certain concept beyond the ISS," Roscosmos Deputy Chief Sergei Savelyev told reporters at the 18th St. Petersburg International Economic Forum.

China and the European Space Agency, he added, were seen as the potential partners in the new strategy, but the key role will belong to Russia.

Russian Deputy Prime Minister Dmitry Rogozin, who is in charge of space and defense sectors, said earlier in the week that Moscow had no plans to extend the operation of the ISS beyond 2020, though the United States had proposed to extend ISS cooperation after that year.

On Tuesday, Rogozin also threatened that from June 1 Moscow would shut down 11 U.S. Global Positioning System (GPS) base stations on Russian territory in response to Washington's anti-Russia sanctions and its refusal to plant Russian Glonass ground base stations on U.S. territory.

Meanwhile, Roscosmos plans to resume talks over the placement of Glonass stations in the United States over the next few weeks, Savelyev said.

"I think it will happen in the very near future, over the next two or three weeks ... It would still give us a chance to walk away from the unpleasant situation over sanctions and continue cooperation," the Interfax news agency quoted the official as saying.

In object oriented programming, "Objects" usually refer to bundles of information. For example, you can describe a Car as having #39;number_of_wheels = 4 #39; and #39;license_plate = 4BIUO11 #39;, and this...

Breakthrough shows how DNA is 'edited' to correct genetic diseases

Posted: at 2:50 am

PUBLIC RELEASE DATE:

Contact: Philippa Walker 44-117-928-8086 University of Bristol

An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients.

Researchers at the Universities of Bristol, Mnster and the Lithuanian Institute of Biotechnology have observed the process by which a class of enzymes called CRISPR pronounced 'crisper' bind and alter the structure of DNA.

The results, published in the Proceedings of the National Academy of Sciences (PNAS) today, provide a vital piece of the puzzle if these genome editing tools are ultimately going to be used to correct genetic diseases in humans.

CRISPR enzymes were first discovered in bacteria in the 1980s as an immune defence used by bacteria against invading viruses. Scientists have more recently shown that one type of CRISPR enzyme Cas9 can be used to edit the human genome - the complete set of genetic information for humans.

These enzymes have been tailored to accurately target a single combination of letters within the three billion base pairs of the DNA molecule. This is the equivalent of correcting a single misspelt word in a 23-volume encyclopaedia.

To find this needle in a haystack, CRISPR enzymes use a molecule of RNA - a nucleic acid similar in structure to DNA. The targeting process requires the CRISPR enzymes to pull apart the DNA strands and insert the RNA to form a sequence-specific structure called an 'R-loop'.

The global team tested the R-loop model using specially modified microscopes in which single DNA molecules are stretched in a magnetic field. By altering the twisting force on the DNA, the researchers could directly monitor R-loop formation events by individual CRISPR enzymes.
