Strange Martian mineral deposit likely sourced from volcanic explosions

In a finding that is soon to be ground-truthed by NASA's next Mars rover, researchers show that a Martian mineral deposit was likely formed by ashfall from ancient volcanic explosions.

Need for rigorous procedures within electrochemical production of ammonia

Many experimental studies of electrochemical synthesis of ammonia are flawed. A new study highlights the need for rigorous protocols moving forward.

Quantum rebar: Quantum dots enhance stability of solar-harvesting perovskite crystals

Engineering researchers have combined two emerging technologies for next-generation solar power -- and discovered that each one helps stabilize the other. The resulting hybrid material is a major step toward reducing the cost of solar power while multiplying the ways it can be used.

Eastern forests shaped more by Native Americans’ burning than climate change

Native Americans' use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a researcher who determined that forest composition change in the region was caused more by land use than climate change.

Developing biosecurity tool to detect genetically engineered organisms in the wild

If a genetically or synthetically engineered organism gets into the environment, how will we tell it apart from the millions of naturally occurring microorganisms? Recently, the US government and research scientists have identified a need for new tools that can detect engineered organisms that have been accidentally or intentionally released beyond the lab. Chemical engineers are developing a detection tool based on DNA signatures.

Flamingoes, elephants and sharks: How do blind adults learn about animal appearance?

They've never seen animals like hippos and sharks but adults born blind have rich insight into what they look like, a new study found.

Bonobo mothers help their sons to have more offspring

New research finds that bonobo mothers take action to ensure their sons will become fathers. This way bonobo mothers increase their sons' chance of fatherhood three-fold.

Staying in shape: How rod-shaped bacteria grow long, not wide

Researchers show how the rod-shaped bacteria Bacillus subtilis maintains its precise diameter while growing end to end.

Resilience of Yellowstone’s forests tested by unprecedented fire

Researchers describe what happens when Yellowstone -- adapted to recurring fires every 100 to 300 years -- instead burns twice in fewer than 30 years. Yellowstone as we know it faces an uncertain future, the researchers say, and one of the big questions they hope to answer is whether the forests can recover.

Researchers document impact of coffee on bowels

Coffee drinkers know that coffee helps keep the bowels moving, but researchers in Texas are trying to find out exactly why this is true, and it doesn't seem to be about the caffeine, according to a new study. Researchers, feeding rats coffee and also mixing it with gut bacteria in petri dishes, found that coffee suppressed bacteria and increased muscle motility, regardless of caffeine content.
