Enjoy NASA's Curiosity rover's view of Gale crater about two years ago. This site has such incredibly beautiful landscapes, but we've gone portrait mode for this one. Notice the rim of the crater in the background. The colors in this image are natural.

It's time for another Trilobite Tuesday. The Trilobita, an extinct class of Paleozoic marine arthropods, was made up of 10 orders, over 150 families, about 5,000 genera, and over 25,000 described species. The diversity of their body configurations is mind-boggling: The eyes of this 1.6-in- (4-cm-) Cybelella, for example, are perched atop calcite-coated stalks that measure more than half its body length at 1-in (2.5 cm) long! This marine arthropod lived during the Upper Ordovician some 450 million years ago.

Metastasis (the spread of cancer from a primary tumor to other parts of the body) causes 90% of cancer deaths. Wenjun Guo, Ph.D., and colleagues found that mutations in MLL3 (a gene frequently mutated or deleted in breast cancer and other human cancers) allow cancer cells to reversibly switch between epithelial and mesenchymal cell states—transitions crucial for enabling cancer cells to adapt to the changing microenvironments they confront on the way to forming metastases.

In a key experiment, the researchers generated mouse mammary stem-cell organoids (clumps of mostly epithelial cells) in which MLL3 was deleted. As shown here, the MLL3 deletions caused many of the epithelial cells (green) to upregulate the mesenchymal marker vimentin (red), indicating the cells’ partial transition to the mesenchymal state. When transitional cells were injected into the tail veins of mice, they readily seeded in the lungs and formed metastases. The researchers also found that BET (bromodomain and extraterminal) protein inhibitors target MLL3-mutant cells in various types of cancer. The findings were published in January 2023 in Nature Cell Biology. Dr. Guo is an associate professor of cell biology at Einstein.

A Cornell study that revealed commercial eastern common bumblebee hives pose a threat to their wild counterparts has led one major pollination company to quickly adapt the bumblebee hive boxes they ship to growers.

The Helix Nebula, NGC 7293, is a planetary nebula formed by the dying star at the center of the blue field.

This star ejected its outer layers as it died, leaving behind a stellar core that emits intense ultraviolet radiation swaddled in a gaseous envelope. That radiation causes the ejected layers to glow.

Photographer Daniel Stern captured this photo in Rio Hurtado, Chile, using a PlaneWave CDK 17 telescope.

Rings and Bar of Spiral Galaxy NGC 1398

Why do some spiral galaxies have a ring around the centre? Spiral galaxy NGC 1398 not only has a ring of pearly stars, gas and dust around its centre, but a bar of stars and gas across its centre, and spiral arms that appear like ribbons farther out.

This deep image from Observatorio El Sauce in Chile shows the grand spiral galaxy in impressive detail. NGC 1398 lies about 65 million light years away, meaning the light we see today left this galaxy when dinosaurs were disappearing from the Earth.

The photogenic galaxy is visible with a small telescope toward the constellation of the Furnace (Fornax). The ring near the centre is likely an expanding density wave of star formation, caused either by a gravitational encounter with another galaxy, or by the galaxy's own gravitational asymmetries.
