The Exolung is aiming for the sweet spot between scuba and snorkeling by using the power of kicking legs to pull a steady supply of air down from the surface.

Proton Technologies will target heavy oil deposits but leave carbon trapped underground.

Four newly-discovered species of shark are capable of trotting around on land, using four fins as stubby legs.

They’re the most recently-evolved types of sharks known to science, according to CNET. And while they still live in the water, using their fins to crawl across coral reefs, they can briefly wriggle across dry land to migrate from one tide pool to another.

Mark 50) is Tony Stark’s fiftieth Iron Man suit. It was built after the Mark XLVII. Mark XLVIII Hulkbuster Mark 2 whilst Mark XLIX is Rescue armor Mark 1 (confirmed by hot toys figure and other merchandise).

The Mark L has been used to battle Thanos and his allies. This armor is more advanced than any other previous armors, the entire armor is stored inside the detachable Arc reactor on Tony’s Chest, it possesses many capabilities and useful functions for Tony to use at his disposal.

Like the Marks XLV, XLVI, and XLVII, this armor has the F.R.I.D.A.Y OS built into it and possesses some of the most advanced technology and weapons compared to other armors Tony Stark has built.

The properties and origin of the solar cycle are still not well understood. They are nevertheless well described by a class of dynamo models that utilize the redistribution of magnetic flux due to systematic plasma flows, such as convection, differential rotation, supergranular diffusion, and meridional flows. These so called Babcock-Leighton-type (BL) dynamos^1,2 have been successful in reproducing the features of solar cycle, including the reversal of the global magnetic field occurring every 11 years, and the propagation of solar activity toward the equator as the cycle progresses. BL dynamos rest entirely on the presence of tilted bipolar magnetic fields, where sunspots usually appear. Grand minima (such as Maunder minimum 1645–1715) are an issue for this class of models, since the needed source terms vanish. There is evidence, however, that solar cycles were present even during these periods³ when almost no spots were seen.

Observers in the Maunder minimum era mostly used smaller refractors, with an estimated angular resolution of 2” at best. Taking into account the seeing, we estimated the resolving power to be around 5”. Therefore they were probably unable to see the tiny spots, i.e., pores. Moreover, there is evidence of a recent secular decrease of solar activity⁴ when small sunspots become more frequent whereas large spots become rarer⁵.

Have you ever thought about speaking up in a meeting and then decided against it because you did not want to appear unsupportive of the group’s efforts?

Or led a team in which the team members were reluctant to express their own opinions?

If so, you have probably been a victim of “Groupthink”.

The ancient frilled shark once lived alongside the T-Rex and has remained evolutionarily unchanged for 80 million years.

After scary news headlines, one study author said she didn’t get to read the final text.
