A few weeks after a magnitude-7.1 earthquake struck central Mexico on Sept. 19, 2017 — leaving hundreds dead and dozens of buildings destroyed — USGS seismologist Elizabeth Cochran and a team of experts mobilized to Mexico City to assess the performance of the Mexico Seismic Warning System (Sistema de Alerta Sísmica Mexicano or SASMEX)  and the public’s perception of the alerts.

The volume of hydraulic fracturing fluid and the location of well pads control the occurrence and frequency of measurable earthquakes, new research from the Alberta Geological Survey and the University of Alberta shows.

Bean plants that suppress secondary root growth in favor of boosting primary root growth forage greater soil volume to acquire phosphorus, according to Penn State researchers, who say their recent findings have implications for plant breeders and improving crop productivity in nutrient-poor soils.

Tropical forests span a huge area, harbor a wide diversity of species, and are important to water and nutrient cycling on a planet scale. But in ancient Amazonia, over 500 years ago, clearing tropical forests was a way of survival to provide land for families to farm and villages to prosper. Researchers at the University of New Hampshire used high-tech tools to more precisely view where these cleared sites were and how much lasting impact they had on the rainforest in the Amazon Basin in South America.

NASA found heavy rainfall in Tropical Cyclone Berguitta as it closed in on Mauritius and Reunion Islands. On Jan. 18, NASA's Terra satellite captured an early morning visible image that showed the center of the storm just south of Mauritius and the storm blanketing both islands. Warnings were in effect for both islands. A tropical cyclone alert class 3 is in effect for Mauritius and La Reunion is on Orange Alert. 

Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun’s gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury’s orbit.

An international review led by the University of Queensland and WCS (Wildlife Conservation Society) says that many native carnivores that live in and around human habitation are declining at an unprecedented rate – spelling bad news for humans who indirectly rely on them for a variety of beneficial services.

Big data and data mining have provided several breakthroughs in fields such as health informatics, smart cities and marketing. The same techniques, however, have not delivered consistent key findings for climate change.

What if you could run your air conditioner not on conventional electricity, but on the sun’s heat during a warm summer’s day? With advancements in thermoelectric technology, this sustainable solution might one day become a reality.

For decades, scientists have known that blue light will make fruit flies go blind, but it wasn’t clear why. Now, a Purdue University study has found how this light kills cells in the flies’ eyes, and that could prove a useful model for understanding human ocular diseases such as macular degeneration.
