In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs -- and offer an extraterrestrial source for mineral mining. But for Georgia Tech researcher Nicholas Hud, asteroids play an entirely different role: that of time capsules showing what molecules originally existed in our solar system. Having that information gives scientists the starting point they need to reconstruct the complex pathway that got life started on Earth.
Focusing science education on students through genetic and genealogical studies may be the way to increase minorities in the pipeline and engage students who would otherwise deem science too hard or too uninteresting, according to a Penn State anthropologist.
After days of lingering off the west Kimberley coast of Western Australia as a slowly organizing low pressure area, Tropical Storm 10S has formed about 50 miles west of Broome, Australia.
Roots face many challenges in the soil in order to supply the plant with the necessary water and nutrients. New work shows that one of these challenges, salinity, can cause root cells to explode if the risk is not properly sensed. Salinity has deleterious effects on plant health and limits crop yields, because salt inhibits water uptake and can be toxic for plants. But plant biologists discovered a never-before-described effect that salt has on the plant cell wall.
NASA-NOAA's Suomi NPP satellite and the GPM core satellite passed over Tropical Cyclone Gita is it began weakening from vertical wind shear.
Scientists have identified a mineral signature for sites that are more likely to contain rare fossils that preserve evidence of soft tissue -- essential information to understanding ancient life.
Sound waves generated by burbling lakes of lava atop some volcanoes point to greater odds of magmatic outbursts. This finding could provide advance warning to people who live near active volcanoes.
Carnegie Mellon University researchers have calculated that the US can meet -- or even beat -- the near-term carbon dioxide emission reductions required by the United Nations Paris Agreement, despite the Trump Administration's withdrawal of the Clean Power Plan (CPP).
A team of Texas A&M AgriLife scientists led by Dr. Charles Randklev in Dallas works alongside collaborators to understand the ecology and taxonomy of Texas' first federally endangered mussel species.
Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest of components: a normal pencil, photocopy paper, and conductive paint are sufficient to convert a temperature difference into electricity via the thermoelectric effect. This has now been demonstrated by a team at the Helmholtz-Zentrum Berlin.
