Even when they are smaller than a short grain of rice, larvae of the Philippine mantis shrimp display ultra-fast movements, according to a new study.
Their ultra-fast punching appendages measure less than 1 millimeter (0.039 inches), and develop right when the larva exhausts its yolk reserves, moves away from its nest, and out into the big wide sea. It immediately begins preying on organisms smaller than a grain of sand.
Although they accelerate their arms almost 100 times faster than a Formula One car, Philippine mantis shrimp (
Gonodactylaceus falcatus) larvae are slower than larger adults, which goes against the theoretical expectation that smaller is always faster.

DURHAM, N.C. – Mantis shrimp don’t need baby food. They start their life as ferocious predators who know how to throw a lethal punch.
A new study appearing April 29 in the Journal of Experimental Biology shows that larvae of the Philippine mantis shrimp (Gonodactylaceus falcatus) already display the ultra-fast movements for which these animals are known, even when they are smaller than a short grain of rice.

RALEIGH –AURA Technologies, a fast-growing artificial intelligence company in Raleigh, has landed a $50 million contract with the US Army Research Office.
The contract includes:
computer vision
image recognition
It’s a big win in terms of financial and news impact for AURA, which launched in 2015.
AURA is coming off a big growth year in 2020 when it cracked the INC. 5000 list of fastest growing privately held companies at No. 125. AURA reported 2,933% growth in revenues over three years.

An MIT team has fabricated a hydrogel-based material that mimics the structure of the lobsters underbelly, the toughest known hydrogel found in nature.

Abstract:
A lobsters underbelly is lined with a thin, translucent membrane that is both stretchy and surprisingly tough. This marine under-armor, as MIT engineers reported in 2019, is made from the toughest known hydrogel in nature, which also happens to be highly flexible. This combination of strength and stretch helps shield a lobster as it scrabbles across the seafloor, while also allowing it to flex back and forth to swim.
