The "very tragic set of events" of the current Ebola outbreak may indeed raise public fears about handling potentially infected samples, said Catharine Conley, Planetary Protection Officer at NASA Headquarters in Washington DC.
"In that context," Conley said, "it is true that the greater public awareness of issues related to hazardous materials not being contained properly, and particularly the unfortunate examples of false negatives - like the person not appearing to be sick when he got off the plane in Dallas - do make it easier to communicate similar concerns in the area of planetary protection."

The current outbreak also highlights "the need to have good protocols in place prior to bringing potentially hazardous materials back to Earth, and having a very careful and well-tested plan for how to determine that they are 'safe,'" Conley told Space.com.
"This is something planetary protection has been working on for quite a while now ... but recent events demonstrate how important it is for Earth safety to avoid false negatives, as well as avoiding false positives to protect human activities at Mars," Conley said.

The chance to explore such radical modifications led Principal Investigator, Catharine Conley, a biologist at NASA Ames, to flatten some already flat-worms (or nematodes).
...
According to Conley, humans die after one minute at 10 G because the blood gets centrifuged from the head.But the worms, with no circulatory system and a sturdy constitution, don't have that problem.In fact, these worms can naturally withstand 1,000,000 G or a force-equivalent of over a million-times their terrestrial weight.
To examine the worms as they spin, scientists are using a video system designed and constructed by students at Harvey Mudd College, Claremont, Calif.
"By looking at what changes occur in the worms when they transition from high-G forces to normal gravity, we think we can predict what will happen to them when they experience near weightlessness during space flight," said Conley."In the future, we want to fly the worms in space, subjecting them to microgravity to see if our predictions are correct."Microgravity (one-million times less than terrestrial levels) is close to 'zero gravity.'
"Radiation levels in space are much higher than they are on the Earth's surface," Conley said."We know that elevated radiation increases the mutation rate of living things.Because these worms reproduce every four days, we can look quickly at many worm generations in space to see how radiation and microgravity may cause changes later," she explained.
...
"Worms have already flown aboard the space shuttle, and it was found that they went through several generations without gross structural changes to their bodies," Conley said.
...
"Should our hypothesis prove correct, it will validate Caenorhabditis elegans [nemotode] as an extremely useful and cost-effective model organism for studying responses to space flight at the molecular, genetic and whole-organism levels," Conley said.
When Conley was planning her current experiments that utilize a smaller, desktop centrifuge, she realized she would need a camera no bigger than an ice cube that could broadcast signals from the spinning apparatus to a TV monitor and recorder in real time.So she turned to the Student Engineering Clinic at Harvey Mudd College to produce the camera system.
...
"During spinning there are changes in the worms' gene expression that seem to help them compensate for the increased apparent gravity, allowing them to survive," Conley said.
