Chinese researchers made a huge splash when they announced that they had used a satellite to distribute quantum-entangled photons between locations 1200 km apart. Media coverage lauded the accomplishment but also emphasized the competition between the Chinese research team and other scientists to demonstrate and develop global quantum networks. Two of the main players in that "quantum space...

Last year planetary scientists Mike Brown and Konstantin Batygin made the case for the existence of a large unseen planet lurking in the outer solar system; they call it Planet Nine. Now, after analyzing the orbits of hundreds of icy objects beyond Neptune, a team of researchers reports no evidence of dynamical effects caused by the hypothetical planet. Although some media outlets reported the...

Some birds have eggs that are nearly spherical; other birds' eggs are wildly elliptical or asymmetric. After studying nearly 50,000 bird eggs, researchers have discovered some clear links between the look of the egg and the traits of the bird. The length of the egg correlates with body size, while the shape of the egg depends on how strong a bird is at flight. This interesting visual story...

Happy birthday Maria Zuber! Born in 1958, Zuber is a geophysicist and the vice president for research at MIT. Zuber grew up in Summit Hill, Pennsylvania, where she spent many nights with her coal-miner grandfather stargazing through a telescope he scrimped to buy. Fascinated by astronomy, Zuber attended the University of Pennsylvania, where she received her BA in both astronomy and geology....

Einstein’s general theory of relativity predicts that in the gravitational field of a massive body, light rays should bend by an angle that depends on the body’s mass. Researchers at the Space Telescope Science Institute have now exploited that effect, known as gravitational lensing, to determine the mass of a star. The new result agrees with astrophysical models of white dwarfs and may help...

Today the Supreme Court announced that it would review President Trump's controversial travel ban, which restricts people from six countries from entering the US. In the meantime, parts of the ban will be allowed to take effect. Physics Today has analyzed the impact of Trump's executive order on scientists and scientific research.

The good news: Although the world is still emitting lots of carbon dioxide, the rate of increase has slowed significantly in recent years. The bad news: The concentration of carbon dioxide in the atmosphere continues to rise at record rates. Climate scientists are trying to figure out why.

At the age of 22 he was appointed physics professor at Glasgow University. Although Thomson had wide interests, including electromagnetism, his research focused on establishing a mathematical framework for...

Science fiction has always had science at its heart, but fan conventions usually focus pretty closely on the books, movies, tv shows, and other media. A convention held here in Washington, DC, has gone out of its way in past years to highlight the real-world science related to the stories and characters that attendees come to celebrate. And this year's convention was no exception, with a...

Jerry Nelson, who along with Terry Mast and George Gabor, created an innovative segmented telescope mirror that has been the basis for both ground- and space-based optical telescopes ever since, has passed away.

The construction of the 5-m Hale Telescope in 1949 pushed the boundaries for single-mirror telescopes. At such a large size the mirror has to be thick enough to support its own weight...

In the US there has been concern for many years among academics of the rise of adjuncts doing most of the teaching at universities, and of temporary contracts for researchers. The same themes also appear in Germany as this piece in Chemistry World points out:

"Around 93% of non-professorial academic staff at German universities are on fixed-term contracts, about half of them shorter than...

Many people, particularly those stuck at Phoenix airport in Arizona, want to know, why is it that when temperatures get too high, planes are grounded? For Bombardier CRJ airliners its around 118 F degrees. Bigger planes from Airbus and Boeing stop flying about 126 F degrees.

Physicist Rhett Allain explains why in Wired.
