A new discovery reveals the least inhabited place on Earth.

The seafloor sediments in the middle of the South Pacific have fewer living cells than anywhere else measured, a new study found.

Oceanographer Steven D’Hondt of the University of Rhode Island and colleagues took a boat out to the middle of the ocean and collected cores, or cylindrical samples of sediment, from the bottom of the sea about 2.5 to 3.7 miles (4 to 6 km) deep.

They found about 1,000 living cells in each cubic centimeter of sediment — a tally that is roughly 1,000 times less than in other seafloor sediments.

“People were previously just taking cores in parts of the ocean fairly close to shore and assuming their results were typical of the ocean as a whole,” D’Hondt told LiveScience.

The NASA Mars Rovers, Spirit and Opportunity, where only designed to operate for 3 months on the Martian surface, but after a five year anniversary, they are still collecting data and exploring the planet.

The rovers are now showing some serious signs of wear and tear.
Spirit has to drive backwards everywhere it goes because of a jammed wheel; and Opportunity’s robotic arm has a glitch in a shoulder joint because of a broken electrical wire.
There have been times also when the vehicles’ have been dangerously short on power because of the dust covering on their solar panels.

Shower-Curtain Effect

“In physics, the shower-curtain effect is the phenomenon in which a shower curtain gets blown inwards with a running shower, regardless of the temperature of the water. The problem of the cause of this effect has been featured in Scientific American magazine, with several theories given to explain the phenomenon but no definite conclusion. [...]

Effects of Radiation on the Human Body

“Effects of Radiation on the Human Body Brain cells do not reproduce, so they’re not damaged directly unless exposure is at 5,000 rems or greater. As with the heart, radiation kills nerve cells and small blood vessels, and can result in seizures and immediate death. ”
