Cement is a remarkable building material; it's cheap, durable and readily available. However, its production is a leading source of carbon dioxide emissions, coughing up 2.8 gigatons of emissions every year, as Advanced Science News reported.

The toxic algae blooms that have killed dogs in Texas, North Carolina and Georgia have been detected in three New York City parks. Parents and pet owners are being warned to keep their kids and dogs away from the infected water, which can be fatal when dogs lap it up, swallow it while swimming, or lick it off their own fur, as the New York Times reported.

The latest renewable energy breakthrough took place over a lunch.
Sudeep Joshi, a postdoctoral fellow at Stevens Institute of Technology, told BBC News that he and some colleagues were discussing the problem of cyanobacteria. These are organisms that can convert sunlight into electric current. The problem? They don't live long enough on artificial lab equipment for researchers to be able to take much advantage of that fact.

The same
red tide choking Florida's Gulf coast has spread to waters off Miami-Dade and Palm Beach counties, forcing the closure of many popular beaches on Thursday and leaving hundreds of dead fish in its wake, according to local reports.
This is the first time in decades the toxic algae has affected both of Florida's coasts at the same time, the
Associated Press reported.
