Aggregate packing density One-dimensional compression strength tests have shown that in MICP-treated sand, at the micro level, the bonds between the calcium carbonate and the aggregates break first, followed by the destruction of calcium carbonate crystals and ultimately the breakage of aggregates20. Maximizing the aggregate content is therefore crucial for achieving high compressive strength of the biocemented material. Packing density optimization allows to increase the volume ratio of aggreg

An international team of scientists from the Schmidt Ocean Institute have captured the first ever footage of a colossal squid — the terrors of the sea that are legendary for both their monstrous proportions and elusiveness — roaming in its natural habitat. But to say it's a big discovery might be misleading. Found lurking in the depths of the South Atlantic Ocean, the specimen is a juvenile mollusk, measuring barely a foot in length. With a transparent body, you might mistake it for some form o

Tyrannosaurus rex may be the most famous dinosaur to ever roam the Earth, but these days, it’s at the center of a very modern problem: the luxury fossil trade. According to a study published in Palaeontologia Electronica, commercial fossil collecting has walled off so many T. rex fossils to scientists that it has severely hindered the scientific record. The study reveals a sobering stat: of the 141 scientifically useful T. rex fossils known to exist, over half—71 specimens—are in private or co

Scientists used precisely controlled soundwaves to suspend insect specimens, capturing detailed photographs from multiple angles without damaging the specimens. Macro photography of small specimens is a routine part of scientific research. However, the typical approach of “posing” subjects using pins can damage sensitive specimens and is not an option at all for the smallest specimens. Researchers from the Institute for Automation and Applied Infomatics, Karlsruhe Institute of Technology; the
