Many media outlets were less than thrilled with the treatment of science in President Trump's recently released budget proposal. Some chose to challenge the Heritage Foundation, the conservative think tank whose ideas are apparently informing the Trump administration's science priorities.

Today is the birthday of John Harrison, a master clockmaker who solved one of the biggest scientific problems of his era: how to determine one’s longitude. He was born in 1693 in Yorkshire, England. The lack of a reliable longitude measure had led to many shipwrecks, and the problem was deemed serious enough for Parliament to offer up to £20 000 for a simple, practical solution. Some thinkers...

"Future historians will look back on the past couple of decades as a time when space-faring nations became focused on, if not obsessed with, exploring Mars." Planetary scientist Ashwin Vasavada lays out the reasons for that obsession in a feature article for Physics Today.

New virtual-reality software allows anyone to explore virtual worlds that don't follow the typical rules of geometry. You can play racquetball on a virtual court on which the ball will always return to where you hit it, no matter which direction you struck it.

The video below takes you on a tour through the Milky Way that focuses on an often overlooked component: dust. It's crucial for astronomers to map the distribution of space dust because it can obscure distant astronomical objects and lead to the misinterpretation of data.

A Tour of the Milky Way and 3-D rendering of space dust

This animation shows a 3-D rendering of dust, as viewed in a several-kiloparsec (thousands of light years) loop through and out of the Milky Way's galactic p...

Today is the birthday of Pierre-Simon Laplace, a renowned mathematician, astronomer, and physicist. He was born in 1749 in Beaumount-en-Auge, France. Between 1770 and his election to the French Academy of Sciences in 1773, he submitted 13 papers to the academy, on such subjects as integral calculus, mechanics, and physical astronomy. His in-depth study of the motions of the planets and the...

The participation of women in science is increasing around the world, a new report shows. But there's still a lot of progress to be made, especially in the physical sciences. Only 21% of physicists and astronomers in the US are women, the report estimates, versus 40% of US scientists in all fields. The report also finds that female scientists publish fewer papers on average than their male...

Sea turtles use ocean currents to their advantage, a new study suggests. After tracking both loggerhead sea turtles and swirling currents called eddies, researchers found that the turtles preferentially spend time in the interior of anticyclonic eddies rather than in the periphery. The waters toward the center of those eddies have conditions more favorable for the turtles' prey to flourish.

Sea turtles don’t just go with the flow

The universe is expanding, and that expansion is speeding up. As distant galaxies continue to recede from us, some of them will disappear behind the cosmic horizon—light from those galaxies will never reach us. The implication: In hundreds of billions of years, residents of our neck of the cosmic woods won't be able to see any galaxies beyond their own. And because they won't see any galaxies,...

The New York Times used data from a recent survey to create six maps that illustrate Americans' thinking about climate change. The survey found that most Americans think that climate change is happening, and they support carbon emission limits from coal power plants. Most Americans also believe that the effects of climate change will harm other Americans—yet the vast majority don't think it...

Today is the birthday of physicist Robert Millikan, whose oil-drop experiment enabled the measurement of the electric charge of the electron, for which he was awarded the 1923 Nobel Prize in Physics. He was born in 1868 in Morrison, Illinois. Millikan first distinguished himself as a teacher and textbook author, producing a number of elementary physics texts that would become classics. But he...

Protons are tiny pieces of matter, but they are not fundamental—they are made up of quarks and gluons. In an effort to decipher the particle's internal structure, researchers took protons and bounced electrons and positrons off them.

The Einstein Fellowship is a great opportunity for researchers who want to think beyond their field of study. Fellows will spend five or six months in the garden cottage of Albert Einstein's summerhouse in Brandenburg and receive a stipend of 10 000 euro. The fellowship is open to people under age 35 who have a degree in the humanities, social sciences, or natural sciences but want to pursue...

The Abel Prize, the mathematics field's answer to the Nobel, has been awarded to Yves Meyer for his work with wavelets. The French mathematician's work has helped researchers in many fields extract useful information from noisy data. In fact, wavelet analysis was crucial in the detection of gravitational waves by LIGO last year. Another fun fact from this Nature article: Meyer's interest in...

Today is the birthday of Halton Arp, an award-winning astronomer known for a unique galactic atlas and for his doubts about Big Bang theory. He was born in 1927 in New York City. Arp's specialty was seeking out unusual galaxies, and in 1966 he assembled a collection of his observations into a book called The Atlas of Peculiar Galaxies. About the same time, Arp also began noticing a number of...

Mars has two moons and no rings. But in about 70 million years, the moon Phobos will get too close to Mars and get torn apart, leading to the formation of rings. A new study argues that the Red Planet may have gone through a cycle of rings and moons: A moon gets torn apart to form rings, and then the material in the rings clumps together to form new moons, and so on.

Does Mars Have Rings? Not Right Now, But Maybe One Day

He's now been in jail for eight months for suspected connections to an organization that allegedly plotted a coup against the country's government. A new article in the New York Times shares Serkan's story. He's been in solitary confinement for six months, his wife says, and he gets...
