Conventional wisdom assumes the ratio of gases in a planet’s atmosphere should match the ratio of gases in the natal disk that birthed it. For the first time, researchers compared gases in a still-forming planet’s atmosphere to its natal disk. Team found the planet surprisingly was less carbon-rich than the disk.
Another advance has been made by experts in nano-scale chemistry to propel further development of sustainable and efficient generation of hydrogen from water using solar power.
In a new international collaborative study – led by Flinders University with collaborators in the USA, South Australia and Germany – experts have identified a novel solar cell process to potentially use in future technologies for photocatalytic water splitting in green hydrogen production.
A new study from the University of Oregon shows how one kind of bacteria, Vibrio cholerae, triggers painful intestinal contractions by activating the immune system. The research also finds a more general explanation for how the gut rids itself of unwanted intruders, which could also help scientists better understand chronic conditions like inflammatory bowel disease.
Stanford scientists have discovered multiple forms of a ubiquitous enzyme in microbes that thrive in low-oxygen zones off the coasts of Central and South America. The results may open new possibilities for growing crops with fewer resources and understanding ocean carbon storage.
Researchers analyzed radioisotopes in layers of fossilized volcanic ash. Decay of uranium to lead within tiny crystals enabled scientists to precisely pinpoint dates for certain events. They determined this event occurred 119.5 million years ago — coincident with evidence for massive volcanic eruptions — and lasted for 1.1 million years. Study results help scientists better understand links between atmospheric CO2 levels, climate changes and conditions in the oceans.
A multi-national, multi-institutional team led by Penn State researchers developed a new tool that enables doctors to examine placentas right at the bedside using just a phone. The tool harnesses computer vision and artificial intelligence to make placenta examination more accessible for low-resource and more-advanced health care institutions alike.
