Nasa 'Could Have Prevented' Astronaut's Near-Drowning In Space Walk

Dusty Space Cloud

This image shows the Large Magellanic Cloud galaxy in infrared light as seen by the Herschel Space Observatory, a European Space Agency-led mission with important NASA contributions, and NASA's Spitzer Space Telescope. In the instruments' combined data, this nearby dwarf galaxy looks like a fiery, circular explosion. Rather than fire, however, those ribbons are actually giant ripples of dust spanning tens or hundreds of light-years. Significant fields of star formation are noticeable in the center, just left of center and at right. The brightest center-left region is called 30 Doradus, or the Tarantula Nebula, for its appearance in visible light.

This enhanced-color image shows sand dunes trapped in an impact crater in Noachis Terra, Mars. Dunes and sand ripples of various shapes and sizes display the natural beauty created by physical processes. The area covered in the image is about six-tenths of a mile (1 kilometer) across. Sand dunes are among the most widespread wind-formed features on Mars. Their distribution and shapes are affected by changes in wind direction and wind strength. Patterns of dune erosion and deposition provide insight into the sedimentary history of the surrounding terrain.

This image obtained by the framing camera on NASA's Dawn spacecraft shows the south pole of the giant asteroid Vesta. Scientists are discussing whether the circular structure that covers most of this image originated by a collision with another asteroid, or by internal processes early in the asteroid's history. Images in higher resolution from Dawn's lowered orbit might help answer that question. The image was recorded with the framing camera aboard NASA's Dawn spacecraft from a distance of about 1,700 miles (2,700 kilometers). The image resolution is about 260 meters per pixel.

This undated photo shows a classic type 1a supernova remnant. Researchers Saul Perlmutter and Adam Riess of the United States and US-Australian Brian Schmidt won the 2011 Nobel Physics Prize on October 4, 2011 for their research on supernovae.

A quartet of Saturn's moons, from tiny to huge, surround and are embedded within the planet's rings in this Cassini composition. Saturn's largest moon, Titan, is in the background of the image, and the moon's north polar hood is clearly visible. See PIA08137 to learn more about that feature on Titan (3,200 miles, or 5,150 kilometers across). Next, the wispy terrain on the trailing hemisphere of Dione (698 miles, or 1,123 kilometers across) can be seen on that moon which appears just above the rings at the center of the image. See PIA10560 and PIA06163 to learn more about Dione's wisps. Saturn's small moon Pandora (50 miles, or 81 kilometers across) orbits beyond the rings on the right of the image. Finally, Pan (17 miles, or 28 kilometers across) can be seen in the Encke Gap of the A ring on the left of the image. The image was taken in visible blue light with the Cassini spacecraft narrow-angle camera on Sept. 17, 2011. The view was obtained at a distance of approximately 1.3 million miles (2.1 million kilometers) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 27 degrees. Image scale is 8 miles (13 kilometers) per pixel on Dione.

Combining almost opposite ends of the electromagnetic spectrum, this composite image of the Herschel in far-infrared and XMM-Newton's X-ray images obtained January 20, 2012, shows how the hot young stars detected by the X-ray observations are sculpting and interacting with the surrounding ultra-cool gas and dust, which, at only a few degrees above absolute zero, is the critical material for star formation itself. Both wavelengths would be blocked by Earth's atmosphere, so are critical to our understanding of the lifecycle of stars . (AFP / Getty Images)

Resembling looming rain clouds on a stormy day, dark lanes of dust crisscross the giant elliptical galaxy Centaurus A. Hubble's panchromatic vision, stretching from ultraviolet through near-infrared wavelengths, reveals the vibrant glow of young, blue star clusters and a glimpse into regions normally obscured by the dust.

A bubbling cauldron of star birth is highlighted in this image from NASA's Spitzer Space Telescope. Infrared light that we can't see with our eyes has been color-coded, such that the shortest wavelengths are shown in blue and the longest in red. The middle wavelength range is green. Massive stars have blown bubbles, or cavities, in the dust and gas--a violent process that triggers both the death and birth of stars. The brightest, yellow-white regions are warm centers of star formation. The green shows tendrils of dust, and red indicates other types of dust that may be cooler, in addition to ionized gas from nearby massive stars.

This composite image shows the central region of the spiral galaxy NGC 4151. X-rays (blue) from the Chandra X-ray Observatory are combined with optical data (yellow) showing positively charged hydrogen (H II) from observations with the 1-meter Jacobus Kapteyn Telescope on La Palma. The red ring shows neutral hydrogen detected by radio observations with the NSF's Very Large Array. This neutral hydrogen is part of a structure near the center of NGC 4151 that has been distorted by gravitational interactions with the rest of the galaxy, and includes material falling towards the center of the galaxy. The yellow blobs around the red ellipse are regions where star formation has recently occurred. (NASA / CXC / CfA / J. Wang)

Kelowna scientist joins NASA funded simulated mission to Mars on Hawaiian mountain

Posted: at 4:44 pm

KELOWNA - A Kelowna scientist is joining the crew of a NASA-funded simulated mission to Mars after beating out hundreds of applicants from around the world.

Ross Lockwood and five others will spend four months inside a sealed environment high on the slopes of a Hawaiian mountain.

The main purpose of the mission, starting March 28, is to help the space agency develop psychological guidelines that will be used to select future astronauts capable of making a real trip to Mars.

``It's incredibly exciting to participate in a research project that will be used to help in space exploration,'' Lockwood said.

``I'm really looking forward to this, but I'm also a little bit nervous as well.''

Lockwood, 27, is doing his doctorate in condensed matter physics at the University of Alberta.

Along with his longtime interest in space-related research and astronomy, Lockwood has worked in educational programs at the University of Alberta Observatory.

His scientific background and experience in various university leadership roles helped him succeed in his application to participate in the simulated Mars mission, which is led by Cornell University and the University of Hawaii.

The researchers will enter the 11-metre diameter dome built in an old rock quarry at an elevation of 2,500 metres on the slopes of Mauna Koa.

Inside the habitat, they will spend several hours a day taking psychoogical tests and continuing with their own research endeavours as part of the venture dubbed HI-SEAS, for Hawaii Space Exploration and Analog Simulation.

Enviornment ministry green light for gene modification field trials: Veerappa Moily

Posted: at 4:44 pm

Environment Minister M Veerappa Moily has cleared a Genetic Engineering Appraisal Committee (GEAC) decision to allow gene modification field trials for certain food crops after the same was put on hold for about a year by his predecessor, Jayanthi Natarajan.

Environment Minister M Veerappa Moily has cleared a Genetic Engineering Appraisal Committee (GEAC) decision to allow gene modification field trials for certain food crops after the same was put on hold for about a year by his predecessor, Jayanthi Natarajan.

While giving his nod, Moily, however, sought to downplay the approval row, saying there was some "misunderstanding" over the issue and there was no "embargo" from Supreme Court on such trials. The minister's nod will pave the way for GM field trails for rice, wheat, maize and cotton.

Moily, however, made it clear that the trials are subject to approval by state governments and fulfilment of certain conditions.

The clearance will enable companies such as Bayer Bioscience, Mahyco and BASF and Monsanto India to carry out field trials for the crops. Bayer Bioscience, for example, has been given clearance to test GM rice across the country.

Earlier, Natarajan had blocked the approval obtained by GEAC in March of last year, reportedly because the issue was pending in the apex court.

But Moily said he had examined the case with officials and found that there was no embargo on the clearance by Supreme Court, Moily said.

"It is a report from a statutory committee. I don't think a ministry or a minister will have any business holding it back. We can't do that. We have to work with the rules... and the law of the land is same for everyone. That is why, as a law-abiding minister, I approved it," Moily told reporters here.

The minister also said that the Environment Ministry, Agriculture Ministry and the Department of Biotechnology had a "common position" on the issue, which would be placed before Supreme Court. Natarajan had, in fact, not "disagreed" with the decision of the GEAC, he further stated.

The next meeting of GEAC has been called on March 21 to discuss some more issues, he said.

Opinion: Three-Parent Babies Are an Ethical Choice

Posted: at 4:44 pm

Perhaps the biggest fear raised by advances in genetic engineering like the ability to create a baby with three parents is that we are heading straight down a road that leads to eugenics the attempt to create perfect "designer" babies.

From "Star Trek" to "Star Wars" to many more films like "Gattaca" and "The Boys from Brazil," Hollywood has warned us time and again that genetic engineering of animals or people is nothing but bad news.

History sadly also shows the horror that eugenics programs have produced in Germany, Japan and many other nations when some people are deemed more desirable and others are seen as defective, burdensome or subhuman. Death camps, forced sterilization, restrictions on marriage, exile, concentration camps, prohibitions on immigration all have all been carried out in the name of eugenics.

But Hollywood is wrong. Not everything about genetic engineering is morally horrible. Nor is human genetic engineering always motivated by eugenic goals.

"Hollywood is wrong. Not everything about genetic engineering is morally horrible."

The FDA is considering approving an experiment to repair a genetic disease in humans by creating embryos with DNA from three parents. Genes would be transferred from a healthy human egg to one that has a disease and the "repaired" egg then fertilized in the hope that a healthy baby will result. The goal of the experiment in genetic engineering is not a perfect baby but a healthy baby.

One in 4,000 children inherit terrible diseases due to genetic mutations in their mitochondria. The mitochondria are the batteries of cells. They provide the energy that lets cells divide and grow. All mitochondria are inherited from the mother from her eggs. And, the mitochondria are separate, tiny units in the egg meaning you can pick them out and transplant them.

So if you know that a mitochondrial disease runs in your family, you might want to try getting pregnant using one of your eggs that has been genetically engineered to have mitochondria from a donor egg.

None of this should raise concerns about abortion. Only eggs, not embryos, would be involved. There are, however, safety concerns. We won't really know if mitochondrial transplants work until healthy young people exist who have been made using the technique. Studies in primates look promising but safety in humans is still a risk.

"How far we go in engineering future generations through genetic manipulations is up to us."

FDA Explores '3-Person' Embryo Fertilization

Posted: at 4:43 pm

By Dennis Thompson HealthDay Reporter

TUESDAY, Feb. 25, 2014 (HealthDay News) -- U.S. Food and Drug Administration hearings opened Tuesday on a controversial fertilization technique that uses the DNA from three people -- two women and one man -- with the goal of preventing inherited genetic diseases.

The technique involves the unfertilized eggs, or "oocytes," from two females. Parts of each egg are combined to weed out inherited genetic disorders contained in one woman's DNA, and the resulting healthy egg is then fertilized using a male's sperm.

The FDA's two-day hearing is meant to provide a forum for discussing how this technique might be tested in human clinical trials.

But the discussion is expected to veer into the ethics of manipulating human genetics to produce "perfect" babies.

"The potential benefits are huge, but the potential harms are also huge," said Dr. Michelle Huckaby Lewis, a faculty member at the Johns Hopkins Berman Institute of Bioethics and the Genetics and Public Policy Center, in Washington, D.C.

The procedure could have unintended health consequences both for newborns and for future generations, as the genetic tinkering reverberates through time, Lewis said.

In addition, she said, the technique raises troubling questions of parental rights and family structure.

"When you use a technology in a new way like this, it really challenges our notions of what it means to be a parent and what it means to be a family," Lewis said.

The hearing was prompted by the work of Shoukhrat Mitalipov, an associate scientist at Oregon Health & Science University (OHSU).

Genetics May Explain Why Autism Is More Common in Boys

Posted: at 4:43 pm

When it comes to developmental disorders of the brain, men and women are not created equal.

Decades of research have shown that males are at far greater risk for neurodevelopmental disorders such as autism spectrum disorder (ASD) than females. Boys, on average, are five times more likely to have autismthan girls.What causes this disparity has largely remained unknown.

Now scientists haveuncovered compelling genetic evidence to explain why the biological scales arent balanced.

According to a team of geneticists in the U.S. and Switzerland,it all boils down to whats called the female protective model. This suggests that girls have a higher tolerance for harmful genetic mutations and therefore require a larger number ofthem than boys to reach the diagnostic threshold of a developmental disorder. With identical genetic mutations, then, a boy could show symptoms of ASD while a girl could show none.

But because the female mutation threshold is higher, when girls are diagnosed with ASD, they tend to fall on the more severe end of the spectrum.

Researchers believe the same dynamic could explain why more boys are diagnosed withADHD, intellectual disabilities and schizophrenia. The findings were published Thursday in the American Journal of Human Genetics.

Geneticists analyzed DNA samples from 16,000 boys and girls with neurodevelopmental disorders.They found that, on average, females diagnosed with ASD had 1.3 to 3 times more harmful genetic alterations than males diagnosed with the disorder.

The findings suggest that as the male brain develops, smaller and more subtle genetic changes can trigger autism spectrum disorders. Female brains require a greater number or severity of mutations before showing symptoms, so their symptoms tend to be worse.

Theres no application in terms of treatment, said study author Sbastien Jacquemont of University Hospital of Lausanne in Switzerland, but it does help understand the inheritance dynamics in families.
