Billionaire’s 2nd SpaceX trip featuring spacewalk aims for early summer launch

Billionaire Jared Issacman, who flew to space once with SpaceX, is already set for launch No. 2 in early summer.

The mission calls for new spacesuits introduced this past weekend designed so the can survive the plan to suck out all of the air of the spacecraft and allow Issacman and a crewmate to make the first commercial spacewalk in history.

Flying on the Crew Dragon Resilience again, the mission dubbed Polaris Dawn is the first of up to three flights Issacman wants to fly, culminating in what is supposed to be the first crewed mission of SpaceX’s Starship.

Josh Mitteldorf on programmed aging

Irina Conboy, Michael Conboy and Josh Mitteldorf discuss one of the central questions in aging research: is aging an active process of the body or is aging a passive process of damage accumulation? See the whole debate on our YouTube Channel: @HealesMovies Josh Mitteldorf, PhD, runs the blog “Aging Matters” (https://joshmitteldorf.scienceblog.com/) and is a consultant in mathematical modeling and creative data analysis. His research areas include evolutionary ecology, biology of aging, and the epidemiology of COVID-19. On the field of aging research, he has published two books,” Cracking The Aging Code”, co-written with Dorion Sagan (https://www.amazon.com/Cracking-Aging-Code-Science-Growing/d…atfound-20 and “Aging is a Group-Selected Adaptation” (https://drive.google.com/file/d/1bs0faQEV3T9cu-Eq079-e5bIGgMwNH08/view).

Molecular analysis confirms T. Rex’s evolutionary link to birds

face_with_colon_three year 2008.

Putting more meat on the theory that dinosaurs’ closest living relatives are modern-day birds, molecular analysis of a shred of 68-million-year-old Tyrannosaurus rex protein — along with that of 21 modern species — confirms that dinosaurs share common ancestry with chickens, ostriches, and to a lesser extent, alligators.

The work, published this week in the journal Science, represents the first use of molecular data to place a non-avian dinosaur in a phylogenetic tree that traces the evolution of species. The scientists also report that similar analysis of 160,000-to 600,000-year-old collagen protein sequences derived from mastodon bone establishes a close phylogenetic relationship between that extinct species and modern elephants.

“These results match predictions made from skeletal anatomy, providing the first molecular evidence for the evolutionary relationships of a non-avian dinosaur,” says co-author Chris Organ, a postdoctoral researcher in organismic and evolutionary biology at Harvard University.

Tweaking the beak: Retracing the bird’s beak to its dinosaur origins, in the laboratory

Year 2015 😗😁

New Haven, Conn. — Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird beaks.

Using the fossil record as a guide, a research team led by Yale paleontologist and developmental biologist Bhart-Anjan S. Bhullar and Harvard developmental biologist Arhat Abzhanov conducted the first successful reversion of a bird’s skull features. The scientists replicated ancestral molecular development to transform chicken embryos in a laboratory into specimens with a snout and palate configuration similar to that of small dinosaurs such as Velociraptor and Archaeopteryx.

Just don’t call them dino-chickens.
