MIT biologists have discovered a fundamental mechanism that helps brain tumors called glioblastomas grow aggressively. After blocking this mechanism in mice, the researchers were able to halt tumor growth.

As a young Marine stationed in South Carolina in 1981, Frank Roberts recognized that the state’s low country was ideal for oyster farming. His family harvested oysters in the Chesapeake Bay and Long Island Sound, and he had a hunch it would work in South Carolina too.

Roberts eventually started his own oyster farm in South Carolina — making a key contribution to a growing nationwide aquaculture trend worth $1.3 billion (2014 figure), with some help from NOAA.  

Olive oil has long been a popular kitchen staple. Yet producing the oil creates a vast stream of wastewater that can foul waterways, reduce soil fertility and trigger extensive damage to nearby ecosystems. Now in a study appearing in ACS Sustainable Chemistry & Engineering, scientists report on the development of an environmentally friendly process that could transform this pollutant into “green” biofuel, bio-fertilizer and safe water for use in agricultural irrigation.

Hurricane Lee continues to strengthen in the Central Atlantic Ocean, and the tiny hurricane appeared well-organized with a clear eye in satellite imagery.

Though you might not think of ants as formidable bodyguards, some do an impressive job protecting plants from enemies. Now, scientists at the University of Toronto have determined what makes some better bodyguards than others.

Examining the relationship between the Amazon rainforest plant Cordia nodosa in Peru and the Amazonian ant Allomerus octoarticulatus, they found the degree to which the ants express two genes significantly impacts the amount of protection they provide to their hosts.
