Young birds suffer in the city

City life is tough for young birds. But if they survive their first year, they are less susceptible to the effects of stress, according to research from Lund University in Sweden.

Satellites Show Hurricane Katia Crawling to the Mexico Coast

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.

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.

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.

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.

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).

U.S. had 15th warmest summer and 3rd warmest year to date on record

From record heat, fires and floods to hurricanes, tropical storms and even an eclipse, August brought a dramatic and — for those along the Gulf Coast — devastating end to summer as Mother Nature demonstrated her power and ability to awe.

Team gathers unprecedented data on atmosphere's organic chemistry

For a few weeks over the summer in 2011, teams of scientists from around the world converged on a small patch of ponderosa pine forest in Colorado to carry out one of the most detailed, extended survey of atmospheric chemistry ever attempted in one place, in many cases using new measurement devices created especially for this project. Now, after years of analysis, their comprehensive synthesis of the findings have been released this week.

As Hurricane Irma Hits the Caribbean, Two More Storms Take Shape in the Atlantic Basin

While Hurricane Irma moves through the Caribbean islands toward South Florida with sustained winds of 185 miles per hour, forecasters are warning that two other major named storms have formed in the Atlantic Basin — Hurricanes Katia and Jose. It is the first time since 2010 that three hurricanes have been active in the region at the same time.
