The Greenland Ice Sheet is the world’s second-largest reservoir of fresh water sitting on the world’s largest island. Suffice it to say: The Greenland Ice Sheet, which contains enough water to refill the Great Lakes 115 times over, is very large. A new study finds that the Greenland Ice Sheet added a quarter inch of water to global sea levels in just the past eight years.

Following Trelles’ lead, Cueto included Wollstonecraft’s work in the catalog bibliography for his own 2002 HistoryMiami Museum exhibit on Cuban flora and fauna without having laid eyes on it or knowing whether it had even survived. Cueto had searched for the manuscript perhaps a hundred times or more in online library catalogs to no avail, but in March 2018, it finally popped up. The author’s name was misspelled as “Wollstonecroft,” reflecting the ambiguous last cursive vowel on the manuscript’s title page.

Now that observatories have begun to record gravitational waves on a regular basis, scientists are discussing how dark matter—only known so far to interact with other matter only through gravity—might create gravitational waves strong enough to be found. Since that first detection, the LIGO collaboration—together with the collaboration that runs a partner gravitational-wave observatory called Virgo—has detected gravitational waves from at least 10 more mergers of black holes and, in 2017, the first merger between two neutron stars. By using gravitational waves to learn about the properties of black holes, LIGO might be able to prove or constrain this dark matter theory.

Even those few modern experimentalists who have won unshared Nobel prizes owe their success to numerous collaborators – especially​ in particle physics and astronomy, which require massive data sets and large teams to analyse them. If the Nobel Prize is a true meritocracy, a scientist should be eligible to win it as many times as she or he makes a prize-worthy discovery. Technically, Arno Penzias and Robert Wilson, co-discoverers of remnants of the early Universe called cosmic microwave background radiation, each won a quarter of the prize; the other half was awarded for completely unrelated work, as a sort of lifetime achievement award to the Russian physicist Pyotr Leonidovich Kapitsa ‘for his basic inventions and discoveries in the area of low-​temperature physics’.

And the institute has hired others: Susan Kaech from Yale, and Kay Tye from M.I.T.

Nearly everyone who has worked there — including the women who sued it — say the Salk Institute has lived up to its founders’ promise in many ways; the lack of bureaucracy facilitates real scientific breakthroughs. As reported by Meredith Wadman in Science that month, eight women, including Emerson and Mellon, accused Verma of sexual assault in a variety of professional situations: pinching the buttocks of a woman who had come to interview for a faculty position; forcibly kissing a young scientist in his lab in 1992; grabbing and kissing Emerson in the Salk library in 2001. Since she was 13 — when she would tag along with her father, a cancer biologist, to his lab — her dream has been a career in academic science, and the Salk seemed like an institution that embodied scientific freedom and creativity.

It’s fast becoming one of the greatest challenges we face in the 21st century,” Walker, an expert in sleep at UC Berkeley and author of the best-selling book Why We Sleep, told a rapt TED audience on Thursday. After a morning of bleak talks on climate change and the harm of viral misinformation online—punctuated by frequent exclamations of “Well, that was alarming” by TED science curator David Biello, and stolen glances at Twitter for updates on the Mueller report and the happenings in the outside world—Walker’s talk felt like a jolt of caffeine to a weary system. After Walker’s talk, he was mobbed by acolytes in the conference center desperate to tell him how much his book—which covers the same topic as his TED talk—changed their lives, how they’d given up caffeine and alcohol and stopped feeling bad for leaving parties early to get sleep or refusing to look at work emails in bed.

For decades, researchers from the Kaua’i-based National Tropical Botanical Garden (NTBG) accessed these cliffs by hiking along treacherous ridgelines and rappelling down vertical cliff faces, scouring each nook and cranny for rare native plants. “Over the last few decades botanists at the NTBG have discovered 11 plant species new to science around the rugged Kalalau cliffs of Kaua’i,” says NTBG research biologist Kenneth R. Wood. The recent drone rediscovery of H. woodii leaves scientists excited about the potential for this technology to find new species—and rediscover ones thought to be extinct—in even the most remote and treacherous areas.

Gaber is also a PhD scientist and a gifted scientific illustrator whose work has been featured on the cover of numerous science journals. Gaber and his daughter, Mi-Ai Parrish, sent off DNA to a consumer genetic testing company called 23andMe to get some information for the family tree. Rubin was also able to help Gaber determine who his paternal father was – ending a mystery that’d persisted for more than 70 years.

In 2013, paleontologist Matthew Borths was doing research at the Nairobi museum for his dissertation on the hyaenodonts, and he asked a curator if he could look at their specimens. So Borths reached out to Ohio University paleontologist and National Geographic grantee Nancy Stevens, who had discovered an important fossil site in Tanzania that’s only a couple of million years older. Stevens later asked Borths to join her lab as a postdoctoral researcher, and together the two returned to the Nairobi National Museum in 2017 to begin analyzing and describing the specimens, which included most of the animal’s jaw as well as bits of skeleton, skull, and teeth.
