Silent hives. Over the last few weeks, several new studies have come out linking neonicotinoids to bee decline. The studies are appearing just as “Silent Spring,” Rachel Carson’s seminal study of the effect of pesticides on wildlife, is about to turn fifty.

Does giving antibiotics to animals hurt humans? The bacon you had for breakfast is at the center of a 35-year debate over antibiotics.

Earth Day ups and downs reflect changing environmental movement. The 42nd Earth Day, held April 22, may not be a round milestone anniversary for those celebrating the annual event devoted to raising awareness about environmental issues, but it will come closer than any in recent memory to the sprit of the first Earth Day held across the U.S. in 1970.

California at top in climate change preparedness  Scarce water supplies and coastal flooding may be part of California’s future, but the Golden State is as ready as any state to tackle those and other problems caused by climate change, according to a national study released Thursday.  California is one of only nine states that have developed comprehensive strategies and implemented policies to deal with water shortages, droughts, a shrinking snowpack and other water-related problems that are expected to occur if global temperatures increase this century as predicted by scientists, the Natural Resources Defense Council report said.

Extreme weather events over the past decade have increased and were “very likely” caused by manmade global warming, a study in the journal Nature Climate Change said on Sunday  Scientists at Germany’s Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global warming. The link between warming and storms was less clear.  “It is very likely that several of the unprecedented extremes of the past decade would not have occurred without anthropogenic global warming,” said the study.

Pre-birth exposures to low doses of a compound—PFOA—that has been widely found in fast food packaging and household products, may increase body weight in women but not men, a new study finds. This is the first time that this chemical, which has been used in the manufacturing of water and stain resistant compounds, has been linked to obesity in humans, although this study was initiated because of research with mice showing that low dose exposures to PFOA in the womb cause post-pubertal weight gain.

EPA issues rules limiting air pollution from fracking.

Cloud computing raises new ethics, sustainability questions  Just a decade ago, it would have been hard for all but the most tech-savvy to imagine the extent of cloud computing today.  The cloud—what some are calling “the factory of the 21st century”—is a complex system of data centers worldwide that store, process and deliver information on demand over the Internet, providing users with resources, applications and information that they previously would have stored locally. The cloud, run by a network of IT service companies, Internet firms and telecommunications services providers, offers services to all of us, from banks and retailers to individuals like you and me. It is both real—requiring traditional inputs such as electricity—and virtual.
