Astronauts as cable guys: Biggest wiring job in space station history (+video)

Posted: February 22, 2015 at 9:45 pm

Cape Canaveral, Fla. Astronauts stepped out on a spacewalk Saturday to perform some tricky cable work needed before new American-made crew capsules can dock at the International Space Station.

It was the first of three spacewalks planned for NASA astronauts Butch Wilmore and Terry Virts over the coming week.

Altogether, Wilmore and Virts have 764 feet of cable to run outside the space station. The longest single stretch, for installation Saturday, is 43 feet.

NASA considers this the most complicated cable-routing job in the 16-year history of the space station. Equally difficult will be running cable on the inside of the complex.

The extensive rewiring is needed to prepare for NASA's next phase 260 miles up: the 2017 arrival of the first commercial spacecraft capable of transporting astronauts to the orbiting lab. NASA is paying Boeing and SpaceX to build the capsules and fly them from Cape Canaveral, which hasn't seen a manned launch since the shuttles retired in 2011. Instead, Russia is doing all the taxi work for a steep price.

The first of two docking ports for the Boeing and SpaceX vessels still under development is due to arrive in June. Even more spacewalks will be needed to rig everything up.

Virts, who arrived at the space station in December, savored the moment as he floated out on his first spacewalk high above the South Pacific. "Pretty cool," Virts said. The men hauled out with them a big white bundle containing cables. Saturday's space walk began at 7:45 a.m. EST and was expected to last 6.5 hours. NASA is broadcastingthe spacewalk live online.

The second spacewalk will be Wednesday and the third on March 1.

Spacesuit concerns stalled the work by a day.

NASA wanted to make certain that the suits worn by Wilmore and Virts had reliable fan and pump assemblies. Two other fan-pump units failed aboard the space station in recent months and were returned to Earth earlier this month for analysis. Corrosion was discovered, the result of water intrusion from testing.

Genetics guru to lecture in Chennai

Posted: at 9:44 pm

Chennai, February 22:

Geneticist Eric Steven Lander who pioneered the general principles for identifying human disease genes and their application to medicine will deliver a lecture in Chennai on Wednesday as part of the Cell Press-TNQ India Distinguished Lectureship Series 2015.

Lander will talk on The Human Genome and Beyond: A 35-year journey of genomic medicine, on February 25, at 6.00 pm at the Sir Mutha Venkatasubba Rao (Lady Andal) Auditorium. N Ram, Chairman and Publisher of The Hindu Group of publications will introduce the speaker, said a press release from the organisers.

Lander who was appointed by US President Barack Obama in 2008 to co chair the US Presidents Council of Advisors on Science and Technology is concurrently Professor of Biology at MIT and Professor of Systems at the Harvard Medical School.

The mathematician turned biologist turned geneticist was one of the principle leaders of the Human Genome Project which mapped the human genetic code between 1990 and 2003.

Cell Press, based in Cambridge, Massachusetts, is an imprint of Elsevier Press which publishes 31 highly cited journals. The Chennai-based TNQ delivers pre publishing services and publishing solutions.

Scientists show DNA evidence can be faked!

Posted: at 9:43 pm

A drinking cup or piece of hair might itself be left at a crime scene to frame someone, but blood or saliva may be more believable.

VIDEO INSIDE

KUALA LUMPUR: DNA evidence is key to the conviction or exoneration of suspects of various types of crime, from theft to rape and murder.

However, the disturbing possibility that DNA evidence can be faked has been overlooked by judges.

Adopting an authentication assay for casework samples as part of the forensic procedure is necessary for maintaining the high credibility of DNA evidence in the judiciary system.

Scientists in Israel have demonstrated that it is possible to fabricate DNA evidence, undermining the credibility of what has been considered the gold standard of proof in criminal cases.

The scientists fabricated blood and saliva samples containing DNA from a person other than the donor of the blood and saliva. They also showed that if they had access to a DNA profile in a database, they could construct a sample of DNA to match that profile without obtaining any tissue from that person.

You can just engineer a crime scene, said Dan Frumkin, lead author of the paper, which has been published online by the journal Forensic Science International: Genetics. Any biology undergraduate could perform this.

Dr. Frumkin is a founder of Nucleix, a company based in Tel Aviv that has developed a test to distinguish real DNA samples from fake ones that it hopes to sell to forensics laboratories.

The planting of fabricated DNA evidence at a crime scene is only one implication of the findings. A potential invasion of personal privacy is another.
