"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."

"Radical changes are coming to transportation."

"ExxonMobil and others pursued research into technologies, yet blocked government efforts to fight climate change for more than 50 years, findings show".

"The first genetically modified food animal has been approved for sale in Canada."

"Genetically engineered crops appear to be safe to eat and do not harm the environment, according to a comprehensive new analysis by the advisory group the National Academies of Sciences, Engineering and Medicine."

"Earlier this month, a U.S. satellite known as F17 — which was primarily used for meteorological measurements — experienced operational failures that compromised the integrity of its data. And while there are similar satellites in orbit that can take over the data collection for now, they’re old enough that scientists are unsure how much longer they’ll last."

"Most food, if we trace it back far enough, began as a seed. And the business of supplying those seeds to farmers has been transformed over the past half-century. Small-town companies have given way to global giants."
