Life & Non-humans

(A) Embryonic tissues elongate via convergent extension, where cell polarization directs active stresses, driving rearrangements (T1 transitions). (B) Fluctuating stresses fluidize tissues, enabling morphogenesis. (C) Key cell processes—force production, polarization, and adhesion—are modeled in robotic units: actomyosin as motorized gears, chemoreceptors as photodiodes, and cadherins as rolling magnets. Polarity conventions differ from biology. (D) Photos of two robotic units (top and isometric views), showing gear rotation and applied forces. Scale bar: 5 cm.

Researchers from Shinshu University and Chiba University develop a novel bio-hybrid drone using odor-sensing antennae from silkworm moths. Incorporation of an electroantennography (EAG) sensor to detect odorants and optimization of the electrode and enclosure structure in the robot enhanced the odor search range, detection precision, and system performance of the drone, thus, improving its application in diverse environments.

Nine years after the 2012 High Park Fire burned a stand of lodgepole pine that had been severely affected by the mountain pine beetle, lodgepole and aspen saplings were rebounding on this slope in the Arapaho and Roosevelt National Forests. A CSU-led study has found that forests are not regenerating fast enough to keep pace with climate change, wildfire, insects and disease. Photo by Katie Nigro, September 2021

A new model upends the decades-old “hard steps” theory that intelligent life was an incredibly improbable event and suggests that maybe it wasn't all that hard or improbable. The team of researchers said the new interpretation of humanity’s origin increases the probability of intelligent life elsewhere in the universe.

The Chinese Pangolin is one of two species that researchers have now provided high-quality, nearly gapless genome sequences and analyzed these for information to aid in conservation of these animals. The Chinese Pangolin and the Malayan Pangolin, also studied here, are listed as critically endangered on the Red List of the IUCN.

NASA’s SPHEREx mission will survey the Milky Way galaxy looking for water ice and other key ingredients for life. In the search for these frozen compounds, the mission will focus on molecular clouds — collections of gas and dust in space — like this one imaged by the agency’s James Webb Space Telescope.

Physiological and behavioral evidence of stress. Left: Schematics of two-photon imaging during baseline and repetitive stress conditions. In repetitive stress sessions, the mice were placed in a 50 ml tube for 30 min to achieve mild stress. The imaging session started directly after the restraint. Individual cells were tracked over imaging days. Shown are examples of 2 imaging planes on day 1 and day 9 (scale bar, 50 μm) and the noise-evoked responses of 3 exemplar cells (mean ± SE).
