  • Last year, Amazon.com founder Jeff Bezos announced that he had located some of the Apollo F-1 rocket engines and planned to recover them
  • his Bezos Expedition team were successful in recovering engines that helped power Apollo astronauts to the Moon and have now brought “a couple of your F-1s home,”
  • There is no indication so far from Bezos of which flight these engines were from
  • ...9 more annotations...
  • Last year
  • he said they had found the engines from Apollo 11, but it may be been difficult to determine exactly which flight the ones found were from
  • NASA launched 65 F-1 engines, five per flight, on 13 Saturn V boosters between 1967 and 1973
  • Supposedly there would be serial numbers to make the identification of which flight these engines were from
  • still on the ship, so perhaps the identification will come later
  • Each of the engines stands 19 feet tall by 12 feet wide and weigh over 18,000 pounds.
  • Five F-1 engines were used in the 138-foot-tall S-IC, or first stage, of each Saturn V
  • three weeks at sea, working almost 3 miles below the surface
  • photographed many beautiful objects in situ and have now recovered many prime pieces

  • The Remotely Operated Vehicles worked at a depth of more than 14,000 feet, tethered to our ship with fiber optics for data and electric cables transmitting power at more than 4,000 volts
  • bringing home enough major components to fashion displays of two flown F-1 engines
  • upcoming restoration will stabilize the hardware and prevent further corrosion

  • Mars explorer once again went into standby status as the result of a software discrepancy — although mission engineers diagnosed the new problem quickly and anticipate having the rover out of safe mode in a couple of days.
  • a very straightforward matter to deal with
  • can just delete that file, which we don’t need anymore, and we know how to keep this from occurring in the future
  • ...6 more annotations...
  • automated fault-protection action, entering ‘safe mode’ at about 8 p.m. PDT (11 p.m. EDT) on March 16,
  • It did not switch to the A-side computer, which was restored last week and is available as a back-up if needed. The rover is stable, healthy and in communication with engineers.
  • safe-mode entry was triggered when a command file failed a size-check by the rover’s protective software
  • Engineers diagnosed a software bug that appended an unrelated file to the file being checked, causing the size mismatch
  • another hiatus — this one planned — will commence on April 4, when Mars will begin passing behind the Sun from Earth’s perspective
  • Mission engineers will refrain from sending commands to the rover during a four-week period to avoid data corruption from solar interference.

Nanoparticles loaded with bee venom kill HIV - 0 views

scibyte86 HIVTreatment

shared by Mars Base on 15 Mar 13 - No Cached
  • Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed
  • The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS
  • hope is that in places where HIV is running rampant, people could use this gel as a preventive measure to stop the initial infection
  • ...15 more annotations...
  • Bee venom contains a potent toxin called melittin that can poke holes in the protective envelope that surrounds HIV, and other viruses
  • in addition to anti-viral therapy, the paper's senior author
  • has shown melittin-loaded nanoparticles to be effective in killing tumor cells.
  • The new study shows that melittin loaded onto these nanoparticles does not harm normal cells
  • because
  • added protective bumpers to the nanoparticle surface
  • When the nanoparticles come into contact with normal cells, which are much larger in size, the particles simply bounce off
  • HIV, on the other hand, is even smaller than the nanoparticle, so HIV fits between the bumpers and makes contact with the surface of the nanoparticle, where the bee toxin awaits
  • , an advantage of this approach is that the nanoparticle attacks an essential part of the virus' structure. In contrast, most anti-HIV drugs inhibit the virus's ability to replicate.
  • this anti-replication strategy does nothing to stop initial infection, and some strains of the virus have found ways around these drugs and reproduce anyway.
  • attacking an inherent physical property of HIV
  • Theoretically, there isn't any way for the virus to adapt to that
  • potential for using nanoparticles with melittin as therapy for existing HIV infections, especially those that are drug-resistant
  • Since melittin attacks double-layered membranes indiscriminately, this concept is not limited to HIV.
  • Many viruses, including hepatitis B and C, rely on the same kind of protective envelope and would be vulnerable to melittin-loaded nanoparticles

shared by Mars Base on 17 Mar 13 - No Cached
  • This week the Curiosity science team released its initial findings from its first ever drilled sample on Mars
  • Curiosity obtained her first drill sample and passed that sample on to her onboard analytical lab instruments, called CheMin and SAM
  • These powerful instruments tell us about what minerals are present in these rocks and whether they contain the ingredients necessary to sustain life as we know it.
  • ...9 more annotations...
  • When we combine what we have learned from our remote sensing and contact science instruments with the data that's coming in from CheMin and SAM, we get a picture of an ancient watery environment, which would have been habitable had life been present in it.
  • the information that we're getting from the CheMin instrument, tells us that the minerals that are present in this lakebed sedimentary rock at John Klein are very different from just about anything we've ever analyzed before on Mars
  • they tell us that the John Klein rock was deposited in a fresh water environment
  • This is an important contrast with other sedimentary environments that we've visited on Mars, like the Meridiani Planum landing site where the Mars Exploration Rover, Opportunity, has been operating since 2004.
  • At that site, the sedimentary rocks record evidence of an environment that was only wet on a very intermittent basis, and when it was, the waters that were there were highly acidic, very salty, and not favorable for the survival of organic compounds.
  • direct contrast to the fresh water environment we're seeing here at the John Klein Site
  • The SAM instrument is telling us that these rocks contained all of the ingredients necessary for a habitable environment
  • We found carbon, sulfur and oxygen, all present and a number of other elements in states that life could have taken advantage of.
  • these few tablespoons of powder from a Martian rock have provided the Curiosity science team with an exciting new dataset
