Two days of satellite imagery from NASA's Terra and NOAA's GOES East satellites showed that Hurricane Katia was starting to crawl to the coast of southeastern Mexico.

Adapted an emergency method for measuring strontium levels in milk so that it can be used in routine studies
Strontium (Sr) is an element which in the event of a nuclear accident is the one that is most released into the atmosphere. The chemical behaviour of strontium is similar to that of calcium and can accumulate in the soil, in plants and in animals (in bones, especially). It is an element with two main radioisotopes (90Sr and 89Sr) which have an effective biological life that is relatively high for human beings, and due to its fixation in the bones, ends up giving a dose of radiation over many years.
What the mud tells us about a changing Arctic
The back deck of the Healy is a tough place to work. It’s wet, it’s cold, and the scientists slogging away there are always covered in mud. That’s because getting samples off the bottom of the Chukchi Sea is an important part of our mission this year.
Mercury convention raises heat on producers
A global commitment to reduce health risks and environmental damage from mercury pollution came into effect last month (16 August), when the so-called Minamata Convention on Mercuryentered into force.
Insect eyes inspire new solar cell design by Stanford researchers
Packing tiny solar cells together, like micro-lenses in the compound eye of an insect, could pave the way to a new generation of advanced photovoltaics, say Stanford University scientists.
In a new study, the Stanford team used the insect-inspired design to protect a fragile photovoltaic material called perovskite from deteriorating when exposed to heat, moisture or mechanical stress. The results are published in the journal Energy & Environmental Science (E&ES).
USGS Installs Storm-Tide Sensors along Florida's Coasts prior to Hurricane Irma's Arrival
Hurricane response crews from the U.S. Geological Survey are installing storm-tide sensors at key locations along Florida’s southeast and southwest coastlines in advance of Hurricane Irma.
Under a mission assignment from the Federal Emergency Management Agency, the USGS is currently deploying approximately 58 storm tide sensors, 24 barometers and five rapid deployment gauges, and is consulting with federal and state partners about the need for similar equipment for other coastal areas farther north along the coastlines.
