"A Mississippi project, a centerpiece of President Obama’s climate plan, has been plagued by problems that managers tried to conceal, and by cost overruns and questions of who will pay."

"Just five months after the Zika virus was declared a global public health emergency, a scientific team’s feverish efforts to create a vaccine against the viral threat have borne promising fruit: With a single shot of either of two different types of vaccine, experimental mice gained near-total immunity to Zika for at least two months."

"Just a week before a Vermont law kicks in requiring labels on food containing genetically modified ingredients, U.S. Senate agriculture leaders announced a deal Thursday that takes the power out of states' hands — and sets a mandatory national system for GM disclosures on food products."

"An airplane powered solely by the sun landed safely in Seville in Spain early on Thursday after an almost three-day flight across the Atlantic from New York in one of the longest legs of the first ever fuel-less flight around the world."

"A solar-powered airplane took off from New York's John F. Kennedy International Airport early Monday, in a bid to have the Solar Impulse 2 craft cross the Atlantic Ocean and land in Spain on Thursday."

"For the first time, carbon dioxide emissions from an electric power plant have been captured, pumped underground and solidified — the first step toward safe carbon capture and storage, according to a paper published Thursday in the journal Science."

"A revolutionary technology known as 'gene drive,' which for the first time gives humans the power to alter or perhaps eliminate entire populations of organisms in the wild, has stirred both excitement and fear since scientists proposed a means to construct it two years ago."

"Coral reefs have almost always been studied up close, by scientists in the water looking at small portions of larger reefs to gather data and knowledge about the larger ecosystems. But NASA's Jet Propulsion Laboratory is taking a step back and getting a wider view, from about 23,000 feet above."

"A team of scientists at Harvard University says it has come up with a bionic leaf — a system that could use solar power and hydrogen-eating bacteria to generate liquid fuel. The findings, described in the journal Science, offer an alternative path to making carbon-neutral solar fuels."

"A new study out this week doesn't show a definitive link, but reopens the debate over whether cell phones cause cancer."
