Study: Space travel causes higher heart rates and more fainting in women than men




Excerpt from 
thespacereporter.com



Space travel has different health effects on men than it does on women, according to a recent study jointly conducted by NASA and by the National Space Biomedical Research Institute (NSBRI).
The study, which looked at 477 male astronauts and 57 female astronauts, all of whom had been to space up to June 2013, was conducted in anticipation of longer duration spaceflights in the future. One of these will include a manned mission to Mars in the 2030s.

Six working groups studied data from the spaceflights in which the astronauts had participated. They concentrated on cardiovascular, sensorimotor, behavioral, musculoskeletal, immunological, and reproductive systems and negative impacts on these due to having spent long periods in space.

In several of these areas, men appear to tolerate spaceflight better than women. Female astronauts tended to experience increased heart rates in times of stress and had higher rates of Urinary Tract Infections (UTIs), as well as higher rates of cancer caused by radiation, than their male counterparts.

After returning to Earth, women astronauts also had a harder time standing without fainting–a condition known as orthostatic intolerance–than did men.

Men were found to be more likely to experience loss of hearing and vision as consequences of space travel, the study indicated.

Behavioral responses appeared the same in both genders.

The study is reported in a recent issue of the Journal of Women’ Health.

Tail Discovered On Long-Known Asteroid

By Scott Sheppard 

A two-person team of Carnegie’s Scott Sheppard and Chadwick Trujillo of the Gemini Observatory has discovered a new active asteroid, called 62412, in the Solar System’s main asteroid belt between Mars and Jupiter. It is the first comet-like object seen in the Hygiea family of asteroids.

Active asteroids are a newly recognized phenomenon. 62412 is only the 13th known active asteroid in the main asteroid belt. Sheppard and Trujillo estimate that there are likely about 100 of them in the main asteroid belt, based on their discovery.

Active asteroids have stable orbits between Mars and Jupiter like other asteroids. However, unlike other asteroids, they sometimes have the appearance of comets, when dust or gas is ejected from their surfaces to create a sporadic tail effect. Sheppard and Trujillo discovered an unexpected tail on 62412, an object which had been known as a typical asteroid for over a decade. Their findings reclassify it as an active asteroid. The reasons for this loss of material and subsequent tail in active asteroids are unknown, although there are several theories such as recent impacts or sublimation from solid to gas of exposed ices.

Discoveries such as this one can help researchers determine the processes that cause some asteroids to become active. Further monitoring of this unusual object will help confirm the activity’s source.

Sheppard and Trujillo have a paper about this work in press at The Astronomical Journal.

Rosetta Mission: European Space Agency Scientists Worry Philae Probe Is Running Out of Battery Power


Philae lander harpooned into comet

Situation Could Mean Early End for Important Experiments on Comet 


Scientists at the European Space Agency fear that the Philae probe now sitting on a comet’s surface may be on the verge of running out of battery power, a scenario that could bring key scientific experiments to a premature end.

The researchers will only know whether the primary batteries have drained or not late Friday, when they try to re-establish a radio link to the probe via Rosetta, a spacecraft in orbit around the comet. The probe and Rosetta can typically communicate twice a day because at other times the orbiter is below the horizon and can’t establish a direct signal.

Scientists are hoping to get contact around 10 p.m. German time, said Stephan Ulamec, who oversees operation for the lander. But if Philae fails to send a signal, he added, it would mean the battery had run out of juice.

The plan was for Philae to do scientific experiments for an initial 2 ½ days on primary battery power and then switch to solar panels that would keep it ticking for another three months. But because of an awkward landing near the face of cliff, the probe’s solar panels are being exposed to far less sunlight than was expected.

Despite the hitch, Philae has already done a significant amount of science on its new home. Its 10 instruments have so far garnered between 80%-90% of the data they were designed to collect, according to Dr. Ulamec.

It has beamed back detailed photographs of the comet’s rough terrain, analyzed the gases, and taken the comet’s temperature. It is now using radio waves to probe the comet’s nucleus and searching for organic molecules on the hostile surface.

Anticipating a possible loss of battery power, ESA scientists activated a drill during their last contact with the lander. The machine is designed to dig up the comet’s subsurface material and rotate it through an onboard oven to investigate its components. 

There may still be a way to extend Philae’s working life. During every 12-hour rotation of the comet, one of the lander’s solar panels is now exposed to an hour and 20 minutes of sunlight, while two other panels get the sun for less than 30 minutes each. 

Provided the signal to Philae can be re-established, scientists said they could rotate the lander slightly so that one of its larger solar panels can catch more sunlight. Another option is to eject the probe from its current location in the hope it lands in a spot where there is more sun.

U.S. Creates Largest Protected Area in the World ~ 3X Larger than California

NEW YORK—The Obama administration announced Thursday that it will create the largest marine reserve in the world by expanding an existing monument around U.S.-controlled islands and atolls in the central Pacific.


The Pacific Remote Islands Marine National Monument will now be nearly 490,000 square miles, nearly three times the size of California and six times larger than its previous size. Commercial fishing, dumping, and mining will be prohibited in the reserve, but recreational fishing will be allowed with permits, and boaters may visit the area.


The protected area that Secretary of State John Kerry announced this morning is actually smaller than the 782,000 square miles that the president initially considered. But environmentalists, preservationists, and conservation groups that had pushed for the expansion called President Barack Obama's designation a historic victory in their efforts to limit the impact of fishing, drilling, and other activities that threaten some of the world's most species-rich waters.

"What has happened is extraordinary. It is history making. There is a lot of reason we should be celebrating right now," said Elliott Norse, founder and chief scientist of the Seattle-based Marine Conservation Institute.


Enric Sala, an ocean scientist and National Geographic Explorer-in-Residence, called the newly expanded monument "a great example of marine protection."


During the past several years, Sala and National Geographic's Pristine Seas project—which aims to explore, survey, and protect several of the last wild places in the world's oceans—have been key players in expeditions to the region that helped to put a spotlight on its biodiversity. Sala also met with White House officials to make the scientific case for expanding the Pacific Remote Islands monument.

In announcing the expansion of protected marine areas, Kerry said, “We’re committed to protecting more of the world's ocean. Today, one to three percent of the ocean is protected, that's it. That's why President Obama will sign a proclamation today that will create one of the largest maritime protected areas in the world. It will be protected in perpetuity.”

Michael Boots, chairman of the White House's Council on Environmental Quality, made clear that by expanding protected areas, the administration sought to balance the need to preserve a range of marine species with concerns from the fishing industry, which had warned about the economic impact of curtailing deep-sea fishing areas.

"We thought [the monument decision] was a good way to balance what the science was telling us was important to protect and the needs of those who use the area," Boots said.


The administration said in a statement late Wednesday that "expanding the monument will more fully protect the deep coral reefs, seamounts, and marine ecosystems unique to this part of the world, which are also among the most vulnerable areas to the impacts of climate change and ocean acidification."


In June, when he first announced his intent to expand the monument, Obama said, "I'm using my authority as president to protect some of our nation's most pristine marine monuments, just like we do on land."


The June announcement was followed by a public comment period and further analysis by the White House, officials said. Thousands of people submitted comments, with many conservation groups and scientists offering their support. Some fishing and cannery groups, as well as a few members of the U.S. Congress opposed the expansion, citing the potential a loss of commercial fishing grounds. 


Norse said that the newly protected areas will safeguard endangered seabirds and other key species, including five endangered sea turtle species (such as loggerheads and leatherbacks), sooty terns and other terns, silky sharks and oceanic whitetip sharks, beaked whales, manta rays, red-tailed tropic birds, and deep-sea corals.

The expanded monument will help ensure that "there are some places that are as pristine as possible for as long as possible," Norse said. "I think a hundred years from now, people will be praising Barack Obama for having the vision to protect the Pacific remote islands."


"A Big Step"


Obama's Democratic administration is building on a national monument that was first created by his predecessor, Republican President George W. Bush, suggesting that "ocean protection may be one of the last bipartisan issues" in the politically divided United States, says David Helvarg, the author of several books on the ocean and the founder of the advocacy group Blue Frontier Campaign.

Democratic and Republican presidents going all the way back to Teddy Roosevelt, a Republican who served from 1901 to 1909, have used the 1906 Antiquities Act to designate national monuments. The law requires simply that an area be unique and considered worthy of protection for future generations. This is the 12th time Obama has used his authority under the Antiquities Act to protect environmental areas.

The area being protected by the administration will expand the protected areas from 50 miles offshore to 200 miles offshore around three areas—Wake Island, Johnston Atoll, and Jarvis Island—the maximum reach of the United States’ exclusive economic zone. The current 50-mile offshore protections around the Howland and Baker islands, and Kingman Reef and Palmyra Atoll, will not change.


"Although 71 percent of our planet is covered with saltwater, we have protected much more of the land than the ocean," Helvarg said. But the newly expanded monument is a big step in the right direction, he added.

Enforcing fishing bans in the monument will be a big challenge, Kerry acknowledged. "Agreements won't matter if no one is enforcing them," he said. "It's going to take training and resources."
Kerry said one measure that could help deter illegal fishing in the region, as well as around the world, would be to implement the Port State Measures Agreement, an international treaty that requires member nations to prevent illegally caught fish from entering the market. Eleven nations or parties have ratified the agreement, but a total of 25 must sign before the treaty will take effect.

"Our goal is to get this done this year," Kerry said.


Meanwhile, efforts to preserve more biologically diverse waters continue.


This week, National Geographic Society announced that it is dramatically expanding its campaign to help protect marine areas, with a goal of persuading governments to officially safeguard more than 770,000 square miles.


The plan, announced by former President Bill Clinton, includes programs that target the Seychelles—an archipelago in the Indian Ocean—northern Greenland, and South America's Patagonia region. The program builds on National Geographic's Pristine Seas project, which has financed ten scientific expeditions to remote areas of ocean around the world, including in the South Pacific and off Africa, Russia, and South America.

The Meaning of Peace in the Bhagavad Gita

V. Susan Ferguson, ContributorThe superb Sanskrit text, The Bhagavad Gita, is an amazing guide and in my view the ultimate ‘user’s manual’ for the human adventure. This ancient text is a dialogue between two mighty warrior heroes: Krishna and Arjuna. Krishna represents the God within us all, who is always waiting patiently to guide us – if we can listen. Arjuna is the greatest warrior of the time and Krishna is his charioteer, his guide in the battle of life. He wil [...]
