The Pelican Nebula is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. [**]
Feast your eyes on the elegant grandeur of the Real Gabinete Português de Leitura (known in English as the Royal Portuguese Reading Room or the Royal Cabinet), a 19th-century library in Rio de Janeiro, Brazil. Constructed from 1880 to 1887 under the direction of architect Rafael da Silva e Castro, the magnificent library has the distinction of holding the largest and most valuable collection of Portuguese works outside of Portugal, with over 350,000 volumes filling its countless bookshelves.
Glaucus atlanticus, the blue dragon (also called sea swallow and blue angel), is a species of small-sized blue sea slug. This tiny animal spends its life floating upside-down on the surface of the Pacific, Atlantic, or Indian Ocean thanks to an air bubble which it swallows and keeps inside its belly, going wherever the currents and the wind take it.
This cute-looking creature is actually an aggressive predator that feeds on organisms much larger than itself, including the most venomous ones. It also can give you a poison sting when picking one up barehanded.
The New Science of Evolutionary Forecasting
Newly discovered patterns in evolution may help scientists make accurate short-term predictions.
Michael Lässig can be certain that if he steps out of his home in Cologne, Germany, on the night of Jan. 19, 2030 — assuming he’s still alive and the sky is clear — he will see a full moon. Lässig’s confidence doesn’t come from psychic messages he’s receiving from the future. He knows the moon will be full because physics tells him so. “The whole of physics is about prediction, and we’ve gotten quite good at it,” said Lässig, a physicist at the University of Cologne. “When we know where the moon is today, we can tell where the moon is tomorrow. We can even tell where it will be in a thousand years.” Early in his career, Lässig made predictions about quantum particles, but in the 1990s, he turned to biology, exploring how genes evolved. In his research, Lässig was looking back in time, reconstructing evolutionary history. Looking ahead to evolution’s future was not something that biologists bothered doing. It might be possible to predict the motion of the moon, but biology was so complex that trying to predict its evolution seemed a fool’s errand. But lately, evolution is starting to look surprisingly predictable. Lässig believes that soon it may even be possible to make evolutionary forecasts. Scientists may not be able to predict what life will be like 100 million years from now, but they may be able to make short-term forecasts for the next few months or years. And if they’re making predictions about viruses or other health threats, they might be able to save some lives in the process. “As we collect a few examples of predictability, it changes the whole goal of evolutionary biology,” Lässig said.
