A third of the population can’t see the Milky Way at night

At night, a river of stars cuts through the dense darkness of space. These celestial bodies form our galaxy’s core and their soft glow earned our galaxy the moniker “Milky Way.” But for more than a third of Earth’s population, the glare of artificial lights conceals this cosmic wonder from view, researchers report June 10 in Science Advances. Nearly 80 percent of North Americans and 60 percent of Europeans can no longer see the galactic core at night, the researchers estimate.

Using a combination of satellite measurements and on-the-ground observations, the researchers assembled the first global atlas of artificial sky luminance, recording light pollution from everything from streetlamps to spotlights. Nearly four in five people worldwide live under light-polluted skies, the atlas reveals. Singapore boasts the brightest nights, the team found, with skies so luminous that no one living there can fully adapt to night vision. Nights are darkest in Chad, the Central African Republic and Madagascar, where more than three-quarters of inhabitants can gaze up at the stars under pristine viewing conditions.
Bright nights aren’t just an eyesore for stargazers. Artificial lights can disrupt wildlife by, for example, confounding sex-seeking fireflies (SN Online: 8/12/15) and misguiding moths (SN: 6/13/15, p. 9).

On a mission for science, on Jupiter and on Earth

I am on a mission. I want everyone to appreciate and understand science — even those who assume (often based on the way they were taught in school) that they don’t like it. Science is important, and frequently amazing. In this issue alone, you can read about the solar-powered spacecraft that, after a five-year journey, will soon arrive at Jupiter to discover what lurks beneath the planet’s blanket of haze and clouds. As NASA’s Juno spacecraft settles into a cloud-skimming series of orbits around the gas giant, it will probe what makes up the planet, its origins and the nature of its core. Learn about efforts to developvaccines for mosquito-ferried scourges , from Zika to dengue. And read about the latest volley in the confounding search for the cause of Alzheimer’s and ancient cave circles built by Neandertals.
Luckily, I work for an organization with a mission aligned with my own. And Society for Science & the Public just got a big boost in its efforts to sow understanding and appreciation of science. On May 26, the Society announced a new sponsor of its flagship competition, the Science Talent Search. Like the science fair I wrote about in the last issue (SN: 6/11/16, p. 2), STS offers young scientists a national stage on which they can shine. Regeneron Pharmaceuticals Inc. of Tarrytown, N.Y., has stepped in to replace Intel, STS sponsor since 1998. (Founded by the Society in 1942, STS was originally sponsored by Westinghouse.)

Regeneron has also upped the game, pledging $100 million over 10 years and increasing the value of the scholarships and other awards to $3.1 million annually. The top student winner will now get $250,000, enough for a full-ride at many universities. “We are over the moon,” Maya Ajmera, CEO and president of the Society and publisher of Science News, told the Washington Post. “Regeneron is truly helping the Society scale its work in an unprecedented way,” she says.
Regeneron, founded in 1988, developed the cholesterol-fighting drug Praulent that went on sale last year and Eylea, used to treat vision diseases such as wet macular degeneration, among other products. Regeneron’s chief scientific officer George Yancopoulos was a top-10 finalist in STS in 1976. Yancopoulos (a former trustee of the Society) and his fellow STS alum Leonard Schleifer, Regeneron CEO and president, now want to give back. “The Westinghouse was a game changer for me as a high school student,” Yancopoulos says. “It truly set me on the path I am on today. I want to be able to grow that ability to motivate the best and the brightest to pursue careers in science.”

Notably, the biotech firm will dedicate $30 million of the total to expand the Society’s efforts in outreach and equity, designed to encourage more young people to engage in original research. In addition to better supporting educators using research-based approaches, the new funds will increase grants to teachers working with underserved students. It will also grow the Science News in High Schools program, sending the magazine to 4,000 more high schools and, I hope, inspiring students to make discoveries of their own.

We are also expanding efforts to get Science News to you. Look for our updated iPad app in July and, coming soon, apps for Android tablets, Kindle Fire and smartphones.
