We know that dogs have a guilty look, but can they actually be guilty? Well, according to this study, the answer is… kind of. Here, researchers show that dogs are capable of “deceptive-like behavior.” In a set of experiments, dogs tended to lead a human “competitor” away from food when that human would keep it for himself. However, the same dogs happily lead their “cooperative” owner to the ...read more

Despite the current administration’s efforts to roll back the Clean Water Act and dismantle the Environmental Protection Agency, interest and participation is growing in a new EPA- and stakeholder-led citizen science project that aims to inform clean water management.
The Cyanobacteria Monitoring Collaborative has been gathering steam since 2010, wh ...read more

Computer chips continue to shrink ever smaller, but we still wring more processing power out of them.
One of the problems that comes with taking our technology to the nanoscale, however, is that we can no longer s ...read more

All life needs phosphorus and agricultural yields are improved when phosphorus is added to growing plants and the diet of livestock. Consequently, it is used globally as a fertilizer – and plays an important role in meeting the world’s food requirements.
In order for us to add it, however, we first need to extract it from a concentrated form – and the supply comes almost exc ...read more

If, like me, you like fossils and you like sharks, you’re in luck. A recent re-look at a fossil found more than a decade ago has answered a big question about the story of sharks’ evolution.
Published recently in American Museum Novitates, a new high-tech reinvestigation of a well-preserved fossil first described in 2003 revealed the animal was more than an Early Devonian sharklike fish.
