Monday’s test firing of Ship 25 seems to have gone resoundingly well. On Tuesday afternoon (June 27), SpaceX tweeted images from the previous day’s proceedings, and they highlight the sheer power generated by Starship’s engines. The smoke and dust from ignition managed to stay low enough to the ground, and diffuse enough, for Starship to remain perfectly in frame, engine fire imparting an orange glow to the black tiles of the vehicle’s heat shield.

SpaceX founder and CEO Elon Musk also tweeted an image from the static-fire test early on Tuesday morning. This one, from an upward perspective, shows the extreme bright light emanating from the flames, with Starship centered in the shine.

A robot fish named Belle could be the “spy on the marine life” that researchers have been looking for.

This isn’t the first time NASA has encouraged the public to add their names to objects bound for space, including those aboard Artemis I, as well the Preservation Rover and InSight on their multiple trips to Mars. In 1977, Voyager 1 and 2 both launched with gold-plated phonographic records aboard featuring 90 minutes of music, including a concerto by Bach and Chuck Berry’s “Johnny B. Goode.”

At the time of writing, over 305,000 people from nearly every nation across the world have already signed the Europa Clipper’s roster, and earthbound participants have until the end of 2023 to enter in their names. Until then, you can also tune into regular livestreams of the Europa Clipper’s construction and assembly.

Four people were locked in a simulated mission to Mars.

A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in eukaryotes—organisms that include fungi, plants, and animals.

In a study published in Nature, the team describes how the system is based on a protein called Fanzor. They showed that Fanzor proteins use RNA as a guide to target DNA precisely, and that Fanzors can be reprogrammed to edit the genome of human cells. The compact Fanzor systems have the potential to be more easily delivered to cells and tissues as therapeutics than CRISPR/Cas systems, and further refinements to improve their targeting efficiency could make them a valuable new technology for human genome editing.

CRISPR/Cas was first discovered in prokaryotes (bacteria and other single-cell organisms that lack nuclei) and scientists including Zhang’s lab have long wondered whether similar systems exist in eukaryotes. The new study demonstrates that RNA-guided DNA-cutting mechanisms are present across all kingdoms of life.

Each fungus may “speak” with many other species— and it turns out they have a lot to say.

For the first time, researchers have shown that reduced oxygen intake, or “oxygen restriction,” is associated with longer lifespan in lab mice, highlighting its anti-aging potential. Robert Rogers of Massachusetts General Hospital in Boston, US, and colleagues present these findings in a study published May 23rd in the open access journal PLOS Biology.

Research efforts to extend healthy lifespan have identified a number of chemical compounds and other interventions that show promising effects in mammalian lab animals— for instance, the drug metformin or dietary restriction. Oxygen restriction has also been linked to longer lifespan in yeast, nematodes, and fruit flies. However, its effects in mammals have been unknown.

To explore the anti-aging potential of oxygen restriction in mammals, Rogers and colleagues conducted lab experiments with mice bred to age more quickly than other mice while showing classic signs of mammalian aging throughout their bodies. The researchers compared the lifespans of mice living at normal atmospheric oxygen levels (about 21%) to the lifespans of mice that, at 4 weeks of age, had been moved to a living environment with a lower proportion of oxygen (11%—similar to that experienced at an altitude of 5,000 meters).
