On 25 May 2014, a rain-on-snow–induced rock avalanche occurred in the West Salt Creek valley on the northern flank of Grand Mesa in western Colorado (United States). The avalanche mobilized from a preexisting rock slide in the Green River Formation and traveled 4.6 km down the confined valley, killing three people.
Researchers have found one of the oldest and most detailed fossils of the central nervous system yet identified, from a crustacean-like animal that lived more than 500 million years ago. The fossil, from southern China, has been so well preserved that individual nerves are visible, the first time this level of detail has been observed in a fossil of this age.
Grasslands across North America will face higher summer temperatures and widespread drought by the end of the century, according to a new study. But those negative effects in vegetation growth will be largely offset, the research predicts, by an earlier start to the spring growing season and warmer winter temperatures.
Medical implants and spacecraft can suddenly go dead, often for the same reason: cracks in ceramic capacitors, devices that store electric charge in electronic circuits. These cracks, at first harmless and often hidden, can start conducting electricity, depleting batteries or shorting out the electronics. Now, researchers have demonstrated a nondestructive approach for detecting cracks in ceramic capacitors before they go bad.
Metabolic phenotyping of blood plasma by proton nuclear magnetic resonance identified unique metabolic biomarkers specific to lung cancer patients and allowed for the accurate identification of a cohort of patients with early and late-stage lung cancer.
