How microbes deep in the earth purify water and accumulate carbon
However, a new study led by biologists at the University of Southern Denmark shows that nutrients may not be so scarce at depth, and microbes have access to a previously unknown source of dissolved organic food.
The sinking particles, called sea snow, begin to release dissolved carbon and nitrogen when they reach depths of 2–6 kilometers, providing nutrients to microbes in the surrounding seawater.
If the particles lose a significant portion of their carbon before they reach the seafloor, there is less carbon in deep-sea sediments than previously thought.
If you ignore the rock-dwelling community, you may miss a critical player in groundwater chemistry.
Archaeologists, who published their vision of what 1924.948 A is in the journal Egypt and the Levant, found traces of characteristic wear at the end of the rod - small grooves and rounding, which indicated that the tool was rotating quickly.
The artifact, just 63 mm long, was discovered in the 1920s in a predynastic burial (circa 3300 BC) in the Badari necropolis.
Chemical analysis showed that the alloy contained arsenic, nickel, as well as lead and silver impurities.
Andrei Sklyarov, who headed the Laboratory of Alternative History, once told Komsomolskaya Pravda about the mysterious technology and know-how of the ancients, who suspected that someone did help the pyramid builders.
American physicists have presented a unique installation in which small balls float in the air under the influence of sound waves and begin to move in a strictly repeating rhythm.
It sounds complicated, but the meaning is simple: just as an ordinary crystal has a repeating “pattern” in space, so here a repeating “pattern” appears in time - the particles go through the same cycle of movement again and again.
The main feature is how the balls “push” each other.
The installation continuously receives energy from the sound source, which allows the system to behave differently than in closed conditions without external recharge.
The discovery was made while studying samples from the asteroid Bennu delivered by NASA's OSIRIS-REx mission.
Early analysis showed the presence of glycine and other amino acids, interstellar dust particles, and traces of reactions with water, organics and saline.
Comparisons with amino acids from the Murchison meteorite, which fell in Australia in 1969, revealed isotope differences not only between objects, but also within the different forms of amino acids from Bennu.
Asteroid Bennu, a large body with an orbit close to Earth, has long been considered a potential threat.
