By Jon CohenFeb. 15, 2017 , 3:30 PM The U.S. Patent Trial and Appeal Board ruled today in favor of the Broad Institute in the high stakes battle over who will control the valuable intellectual property linked to CRISPR, the powerful genome-editing tool. The ruling came after the feature below, from the 16 February issue […]
By Sarah McQuateFeb. 18, 2017 , 12:15 PM BOSTON—Chesapeake Bay oysters that lived a half a million years ago were on average 1.5 times bigger than the oysters in the bay today, researchers reported here yesterday at the annual meeting of AAAS, which publishes Science. These ancient oysters also lived about four times as long as […]
By Elizabeth PennisiFeb. 24, 2017 , 1:15 PM WASHINGTON, D.C.—When it comes to genome sequencing, visionaries like to throw around big numbers: There’s the UK Biobank, for example, which promises to decipher the genomes of 500,000 individuals, or Iceland’s effort to study the genomes of its entire human population. Yesterday, at a meeting here organized […]
By Gretchen VogelMar. 16, 2017 , 2:45 PM The United Kingdom’s first baby resulting from a controversial assisted reproduction technique could be born by early next year. Regulators there have granted the country’s first license for a technique that would allow some women to avoid passing on a type of inherited disease by combining genes […]
By Patrick MonahanMar. 20, 2017 , 1:00 PM It’s hard to take a picture of something that’s always moving—just ask anyone who’s had to photograph a child. Now, one team of researchers has solved the problem on a tiny scale, with a program that lets microscopes automatically track objects invisible to the human eye. Normally, […]

By Patrick MonahanMar. 31, 2017 , 2:00 PM Biologists sometimes use the phrase “arms race” to describe an evolutionary tug-of-war, but it’s rarely this literal. Microbes called dinoflagellates (above) have developed intricate weapons—including a microscopic version of a Gatling gun—to harpoon their dinners, a new study shows. Scientists have known about these harpoons for decades, […]
Mar. 9, 2017 , 11:15 AM Prochlorococcus is thought to be the most abundant photosynthetic organism—why don’t we know more about it? Learn more.
By David ShultzMar. 14, 2017 , 2:00 PM Life forms that eventually gave rise to animals and plants may have appeared on Earth 400 million years earlier than previously believed. That’s the conclusion a team of scientists is making after discovering 1.6-billion-year-old fossilized cells in sedimentary rocks collected from central India. Based on their size, […]
By Patrick MonahanMar. 14, 2017 , 4:30 PM Ants have all sorts of jobs we normally think of as human, from architect to farmer to insect-in-chief. Now, scientists are adding one more occupation to that list: chemist. A new study shows that wood ants protect their colonies from disease by crafting a potent antibiotic “cocktail” […]
