To find answers, oceanographers install observatories beneath remote seafloor
Of all the habitable parts of our planet, one ecosystem still remains largely unexplored and unknown to science: the igneous ocean crust. (more…)
A new study finds that low concentrations of the chemical methylisothiazolinone has subtle but measurable negative effects on the neural development of tadpoles. The chemical is found in some cosmetics, although the study does not provide any evidence that cosmetics are unsafe for humans. (more…)
*Berkeley Lab scientists push chemistry to the edge, testing plans for a new generation of light sources*
For Ali Belkacem of Berkeley Lab’s Chemical Sciences Division, “What is chemistry?” is not a rhetorical question.
“Chemistry is inherently dynamical,” he answers. “That means, to make inroads in understanding – and ultimately control – we have to understand how atoms combine to form molecules; how electrons and nuclei couple; how molecules interact, react, and transform; how electrical charges flow; and how different forms of energy move within a molecule or across molecular boundaries.” The list ends with a final and most important question: “How do all these things behave in a correlated way, ‘dynamically’ in time and space, both at the electron and atomic levels?” (more…)
*The team scoured more than 500 museum drawers of Green River fossils for crickets and katydids with intact front legs, looking for evidence of ears.*
How did insects get their hearing? A new study of 50-million-year-old cricket and katydid fossils sporting some of the best preserved fossil insect ears described to date are helping to trace the evolution of the insect ear.
According to paleontologist Dena Smith of the University of Colorado Boulder’s Museum of Natural History and University of Illinois Professor Roy Plotnick, who collaborated on the new study at the National Evolutionary Synthesis Center, or NESCent, in Durham, N.C., insects hear with help from some very unusual ears.

Biologists have learned in recent years that wild chilies develop their trademark pungency, or heat, as a defense against a fungus that could destroy their seeds. But that doesn’t explain why some chilies are hot and others are not.
New research provides an answer: Hot chilies growing in dry areas need more water to produce as many seeds as non-pungent plants, but the Fusarium fungus is less of a threat in dryer environments so chilies in those areas are less likely to turn up the heat. In wetter regions, where Fusarium thrives, wild chilies build up their reserves of spicy capsaicin in self-defense. (more…)
EAST LANSING, Mich. — A Michigan State University researcher is working with vintners to introduce passito, an age-old Italian wine to the United States. (more…)
*Combination of colossal canines and forceful forelimbs arose repeatedly over time*
The toothiest prehistoric predators also had beefier arm bones, according to results of a study published today in the journal Paleobiology.
Saber-toothed tigers may come to mind, but these extinct cats weren’t the only animals with fearsome fangs.
Take the false saber-toothed cats–also known as nimravids–and their catlike cousins, a family of carnivores called the barbourofelids. (more…)
EAST LANSING, Mich. — Two teams of Michigan State University researchers – one working at a medieval burial site in Albania, the other at a DNA lab in East Lansing – have shown how modern science can unlock the mysteries of the past. (more…)
