In 2014, scientists found a giant 30,000 year old virus in Siberian permafrost. The virus, Pithovirus sibericum, was still infectious and began killing amoebas. This raised concerns that melting or drilling arctic ice could unearth previously undiscovered pathogenic viruses.

Pithovirus Pithovirus, first described in a 2014 paper, is a genus of giant virus known from two species, Pithovirus sibericum, which infects amoebas and Pithovirus massiliensis. It is a double-stranded DNA virus, and is a member of the nucleocytoplasmic large DNA viruses clade. The 2014 discovery was made when a viable specimen was found in …

In 1969, at the height of the Cold War, the Apollo 11 crew carried commemorative medals to the moon to honor two Soviet cosmonauts who died as part of the USSR’s human spaceflight program

Statement About Honoring American and Russian Space Heroes During the Apollo 11 Mission THE TWO MEN we hope will set foot on the moon represent all mankind. Their achievement will be the world’s achievement. It is fitting, therefore, that the first lunar explorers carry with them some recognition of the sacrifice made by other space …

The 2011 earthquake off the coast of Japan was so powerful – measuring almost 9.0 on the Richter scale – it moved Japan 8 feet closer to North America and shifted the planet on its axis, causing the length of a day to shorten by almost 1.8 microseconds

Quake moved Japan coast 8 feet, shifted Earth’s axis (CNN) — The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis. “At this point, we know that one GPS station moved (8 feet), and we …

Buzz Aldrin, the second man on the moon, singlehandedly calculated an orbital technique called “Mars Cycling” which would allow for spacecraft to perpetually travel between Earth and Mars with only a single initial boost. Crew would board and return via a secondary spacecraft, saving fuel.

Mars cycler Buzz Aldrin, discoverer of the Aldrin cycler A Mars cycler (or Earth–Mars cycler) is a kind of spacecraft trajectory that encounters Earth and Mars regularly. The term Mars cycler may also refer to a spacecraft on a Mars cycler trajectory. The Aldrin cycler is an example of a Mars cycler. Cyclers are potentially …

Purple is a “non-spectral color”, which means that it exists only in our minds: there is no wavelength of light that corresponds to it. Our brain perceives purple when it sees a mixture of strong red and strong blue light, without any green.

Color Perception The properties of color which are inherently distinguishable by the human eye are hue, saturation, and brightness. While we know that the spectral colors can be one-to-one correlated with light wavelength, the perception of light with multiple wavelengths is more complicated. It is found that many different combinations of light wavelengths can produce …

Neanderthals, which were traditionally thought of as extremely primitive humans, are now believed to have been extremely intelligent, even comparable to the intelligence of modern humans. They used tools, had social structures, thrived in hostile environments, and lived long lives.

Rethinking Neanderthals Bruno Maureille unlocks the gate in a chain-link fence, and we walk into the fossil bed past a pile of limestone rubble, the detritus of an earlier dig. We’re 280 miles southwest of Paris, in rolling farm country dotted with long-haired cattle and etched by meandering streams. Maureille, an anthropologist at the University …

Meet Kauaʻi ʻōʻō, a now-extinct species of bird, endemic to the island of Kaua’i in Hawaii. The last individual ever was a male, and he was recorded singing a mating call, to a female that would never come. He died in 1987.

Kauaʻi ʻōʻō The Kauaʻi ʻōʻō or ʻōʻōʻāʻā (Moho braccatus) was a member of the extinct genus of the ʻōʻōs (Moho) within the extinct family Mohoidae from the islands of Hawai’i. It was previously regarded as member of the Australo-Pacific honeyeaters (family Meliphagidae). This bird was endemic to the island of Kauaʻi. It was common in …

Helium can’t be artificially produced and is formed in natural gas wells as ancient uranium decays. The half-life of the most prevalent uranium isotope is billions of years old (older than Earth itself), so helium takes inordinate amounts of time to form.

Scientists Found a Huge Reservoir of Much-Needed Helium The federal government stockpiles it. Scientists hoard it. Entire industries—and even lives—could end without it. In this case, the “it” in question is helium, a gas used in everything from particle accelerators to MRI machines. A dearth of helium has long been of grave concern to researchers. …

Fish eggs can survive and hatch after passing through a duck, providing one explanation of how seemingly pristine, isolated bodies of water can become stocked with fish

Fish Eggs Can Survive a Journey Through Both Ends of a Duck In lakes and pools that appear physically cut off from other bodies of water, fish sometimes seem to materialize out of nowhere. This somewhat mystical sounding theory might not be far off: a new study suggests fish eggs may simply fall from the …
