Cygnus cargo craft readies to leave space station

Posted: at 11:46 pm

A private cargo ship built by Orbital Sciences Corporation is preparing to leave the International Space Station early Tuesday and burn up on re-entry into Earth's atmosphere, NASA said Monday.

The Cygnus spacecraft is scheduled to detach from the orbiting research outpost at 1000 GMT Tuesday and leave the ISS an hour and a half later.

"Orbital engineers then will conduct a series of planned burns and maneuvers to move Cygnus toward a destructive re-entry in Earth's atmosphere," NASA said in a statement.

Orbital said Cygnus is expected to re-enter the atmosphere on Wednesday, October 23 at 1818 GMT over the Pacific Ocean east of New Zealand.

The unmanned spaceship attached itself to the ISS on September 29, marking the first successful demonstration mission of a cargo resupply flight by Orbital Sciences.

It is the fourth such mission by a private company to ferry supplies to global astronauts, a capacity the United States lost when the space shuttle program ended in 2011.

The California-based SpaceX, owned by entrepreneur Elon Musk, in 2012 became the first private enterprise to send its own cargo-bearing spacecraft to the ISS and back.

Both companies have billion-dollar NASA contracts to deliver cargo to the ISS on multiple missions over the coming years.

Unlike SpaceX's Dragon capsule, Cygnus cannot return to Earth intact and will be destroyed after its mission is complete.

NASA Space Station Astronaut Calls Home to Speak with Minnesota Students

Posted: at 11:46 pm

NASA astronaut and Expedition 37 flight engineer Karen Nyberg, currently orbiting aboard the International Space Station, will speak with students in Henning, Minn., near her hometown, this week.

The live, station-to-ground video chat will take place at 9:45 a.m. CDT (10:45 a.m. EDT) Wednesday, Oct. 23, at the Henning School, 500 School Ave. It will be carried live on NASA Television and the agency's website.

Nyberg, who arrived at the station in May for a six-month mission, is a graduate of Henning, a small, rural school with an enrollment of approximately 400 students in grades K-12. During the event, the students will be able to ask Nyberg questions about life, work and research aboard the orbiting laboratory.

Media interested in attending the event can do so by contacting Henning School Principal Thomas Williams at 218-583-2927, ext. 8157, or twilliams@henning.k12.mn.us.

The students have been following Nyberg's mission, and NASA activities have been incorporated into classes at the school in preparation for the conversation. Linking students directly to astronauts aboard the space station provides them with an authentic, live experience of space exploration, space study and the scientific components of space travel and possibilities of life in space.

This in-flight education downlink is one in a series with educational organization in the United States to improve science, technology, engineering and mathematics (STEM) teaching and learning. It is an integral component of NASA's Teaching From Space education program, which promotes learning opportunities and builds partnerships with the education community using the unique environment of space and NASA's human spaceflight program.

Family of missing toddler Ben Needham seek DNA tests on mystery Greek girl

Posted: at 11:45 pm

The family of a missing British toddler has called for DNA tests to be carried out on children found at Roma settlements - starting with the allegedly abducted little girl discovered earlier this week in Greece.

The sister of Ben Needham, a 21-month-old toddler who was abducted from his grandparents home on the island of Kos in 1991, said she wanted police to carry out an investigation based on her own DNA beginning at the encampment near Farsala.

The settlement is at the centre of an international appeal to find the parents of a four-year-old girl, known only as Maria, who police believe may have been abducted.

An officer looked into Marias case when he saw the blonde-haired and blue-eyed child living in squalid conditions with a Roma couple and 13 other children whom she looked nothing like.

DNA tests confirmed that she was not related to the 39-year-old man and 40-year-old woman with whom she lived, and the couple have now been arrested on abduction charges.

The case has sparked new hope for the Needhams, who say they were told at the time by police that there was no way their toddler could have been abducted by Roma groups.

Bens mother Kerry told ITV: My family and I are extremely delighted at the news that a four-year-old girl has been found in a gypsy camp in Larissa, Greece.

We have always believed that Ben's abduction was gypsy-related and have had a long ongoing inquiry in Larissa. We hope that the investigation into Ben's disappearance will now be looked at again.

Ben's sister LeighannaNeedham, who at 20 had not been born when he went missing, said the discovery of Maria in the gypsy camp was welcome news and said DNA tests could be used to find Ben or perhaps even his children.

It's given us great hope, she told Sky News yesterday.

Florida Escape Probers Testing Forgeries for DNA

Posted: at 11:45 pm

Scientists are DNA testing the forged documents that allowed two convicted murderers to escape from a Florida prison as the two recaptured men are being questioned about possible accomplices.

Laboratory scientists in Pensacola, Fla., are testing the forged documents for DNA today, using a method called Touch DNA, according to the Florida Department of Law Enforcement.

Touch DNA is a method that analyzes skin cells possibly left on evidence.

FLDE Commissioner Gerald Bailey has indicated that more arrests would be made in connection with the jailbreak.

Agents are also back at Bay County Jail questioning Joseph Jenkins and Charles Walker.

Jenkins and Walker were apprehended without incident at the Coconut Grove Motor Inn in Panama City Saturday evening, officials said.

Law enforcement officials believe the two men may have paid someone thousands of dollars to create the forged release paper they used to con officials.

Shortly after 5 p.m. Saturday, about 20 members of the task force surrounded the hotel and told Jenkins and Walker to come out. About a minute later, both men came out with their hands in the air and were taken into custody without incident.

When the two convicted killers emerged from room 227, where they had been holed up, they told officials "they were relieved that it was over," U.S. Marshals Service Chief Inspector Frank Chiumento said.

The two convicted murderers who used forged documents to walk out of a Florida prison are not cooperating with investigators trying to find out where they got to phony release letters, police sources said.

Agents have been questioning Joseph Jenkins and Charles Walker at Bay County Jail since they were taken back into custody on Saturday, but neither man has answered any questions about possible accomplices, police said.

Laboratory scientists in Pensacola, Fla., were testing the forged documents for DNA today, using a method called Touch DNA, according to the Florida Department of Law Enforcement.

Touch DNA is a method that analyzes skin cells possibly left on evidence.

FLDE Commissioner Gerald Bailey has indicated that more arrests would be made in connection with the jailbreak.

Agents have pinpointed suspects for possible arrest and are building a case against them, but do not have any arrest warrants at this time, police said this evening.

Jenkins and Walker were apprehended without incident at the Coconut Grove Motor Inn in Panama City on Saturday evening, officials said.

Surprises discovered in decoded kiwifruit genome

Posted: at 11:45 pm

Provided

The recent decoding of the kiwifruit genome has discovered that the fruit has many genetic similarities to other plant species, including potatoes and tomatoes, among other surprises.

A new study that decoded the DNA sequence of the kiwifruit has concluded that the fruit has many genetic similarities between its 39,040 genes and other plant species, including potatoes and tomatoes. The study also has unveiled two major evolutionary events that occurred millions of years ago in the kiwifruit genome.

The kiwifruit is an economically and nutritionally important fruit crop. It has long been called the king of fruits because of its remarkably high vitamin C content and balanced nutritional composition of minerals, dietary fiber and other health-benefits, says Zhangjun Fei, a scientist from the Boyce Thompson Institute at Cornell who contributed heavily to study, which was conducted by a team of plant scientists from the United States and China and published Oct. 18 in Nature Communications.

The genome sequence will serve as a valuable resource for kiwifruit research and may facilitate the breeding program for improved fruit quality and disease resistance, Fei says.

Kiwifruit originated from the mountains and ranges of southwestern China and was not really known to the world until the early 20th century, when farmers in New Zealand discovered the fruit and began breeding it as a commercial crop. It is a form of berry that grows on woody vines, much like grapes, and belongs to the order of Ericales, where blueberries, tea bushes and Brazil nuts are also classified.

One of the most remarkable findings of the study was uncovered when scientists observed a high percentage of similarities within the kiwifruit DNA. The data revealed two unusual mishaps that occurred in the process of cell division about 27 and 80 million years ago, when an extensive expansion of genes arose from an entire extra copy of the genome, followed by extensive gene loss.

Fei explains, The kiwifruit genome has undergone two recent whole-genome duplication events.

When genes are duplicated, the extra genes can mutate to perform entirely new functions that were not previously present in the organism. This process, called neofunctionalization, can occur with no adverse effects in plants and, in the case of kiwifruit, was quite beneficial.

The duplication contributed to adding additional members of gene families that are involved in regulating important kiwifruit characteristics, such as fruit vitamin C, flavonoid and carotenoid metabolism, says Fei.
