The UK's Drop in CO2 Emissions Shows the Power of Carbon Taxes

A new analysis indicates that the UK’s CO2 output is at a record low, and it’s largely down to one major action: a reduction in coal use.

Switzerland could generate more energy out of used wood

Switzerland is not fully exploiting a significant source of clean energy: 173,000 tonnes of used wood could be re-used producing valuable heat and power energy today, in addition to the 644,000 tonnes of used wood already being used. This was the conclusion reached by a nationwide survey conducted by the Swiss Federal Research Institute for Forest, Snow and Landscape Research (WSL) among 567 companies in the construction, waste management and transport sectors.

Atomic map gives malaria drug new lease on life

Researchers have for the first time mapped how one of the longest-serving malaria drugs works, opening the possibility of altering its structure to make it more effective and combat increasing malaria drug resistance.

Looking for 'fingerprints' at the intersection of weather and climate

Scientists have found the seasonal “fingerprints” of Arctic sea ice, El Nino, and other climate phenomena in a new study that probes the global interactions between weather and climate.

Plants Might Have Saved Earth From Permanent Ice Age

In the last 800,000 years, Earth has chilled and thawed its way through eight ice ages, each lasting tens of thousands of years. But why? Why didn’t Earth just freeze the one time and stay that way?

Salad bars in public schools: How to get kids to use them

Thanks to a national initiative, salad bars are showing up in public schools across the country. Now a Brigham Young University researcher is trying to nail down how to get kids to eat from them.   

Star discovered in closest known orbit around black hole

Astronomers have found evidence for a star that whips around a black hole about twice an hour. This may be the tightest orbital dance ever witnessed for a black hole and a companion star.

New research urges a rethink on global energy subsidies

The hidden toll that subsidies for electricity, fossil fuels, and transport have on social welfare, economic growth and technological innovation needs to be exposed through better research says a new paper in Ecological Economics by Benjamin K Sovacool.

Energy subsidies, which have mostly supported fossil fuels and nuclear power over the previous half century, have historically kept energy prices artificially low, compared to market rates. But they come at a high cost to governments and taxpayers. The Indian government, for example, spends as much as it does on fuel subsidies for kerosene and liquid propane, used to light rural houses, as it does on education. India subsidises fossil energy consumption by $21 billion every year, which works out at $16 per person. Given that 500 million of its people live on less than $2 per day, this is a surprisingly large amount.

Stanford scientists map seawater threat to California Central Coast aquifers

Researchers from Stanford and the University of Calgary have transformed pulses of electrical current sent 1,000 feet underground into a picture of where seawater has infiltrated freshwater aquifers along the Monterey Bay coastline.

The findings, which will be published in an upcoming issue of the Journal of Hydrology but are available online now, help explain factors controlling this phenomenon, called saltwater intrusion, and could help improve the groundwater models that local water managers use to make decisions about pumping groundwater to meet drinking or farming needs.

"Preventable" asthma attacks in Houston cost millions

“Preventable” asthma attacks among schoolchildren cost millions in health care dollars over 10 years, according to a new study by the city of Houston, Rice University and the Houston Independent School District (HISD).

The revelation is part of a project that seeks to minimize risk to students by showing where, when and how often emergency medical crews were called to treat “uncontrolled” asthma attacks at public schools in Houston and at students’ homes.
