Scientists capture X-rays from upward positive lightning

Scientists capture X-rays from upward positive lightning

Globally, lightning is responsible for over 4,000 fatalities and billions of dollars in damage every year; Switzerland itself weathers up to 150,000 strikes annually. Understanding exactly how lightning forms is key for reducing risk, but because lightning phenomena occur on sub-millisecond timescales, direct measurements are extremely difficult to obtain. Now, researchers from the Electromagnetic Compatibility … Read more

New offshore wind turbines can take away energy from existing ones

New offshore wind turbines can take away energy from existing ones

As summer approaches, electricity demand surges in the U.S., as homes and businesses crank up the air conditioning. To meet the rising need, many East Coast cities are banking on offshore wind projects the country is building in the Atlantic Ocean. For electric grid operators, knowing how much wind power these offshore turbines can harvest … Read more

The longer spilled oil lingers in freshwater, the more persistent compounds it produces

The longer spilled oil lingers in freshwater, the more persistent compounds it produces

Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. And, according to research published in ACS’ Energy & Fuels, the longer that oil remains in … Read more

Warming Arctic reduces dust levels in parts of the planet

Warming Arctic reduces dust levels in parts of the planet

Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. SEAS researchers found that the decrease in dust … Read more

How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon

How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon

In looking up at the sky during these early weeks of spring, you may very well see a flock of birds moving in unison as they migrate north. But how do these creatures fly in such a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports … Read more

Artificial intelligence helps scientists engineer plants to fight climate change

Artificial intelligence helps scientists engineer plants to fight climate change

The Intergovernmental Panel on Climate Change (IPCC) declared that removing carbon from the atmosphere is now essential to fighting climate change and limiting global temperature rise. To support these efforts, Salk scientists are harnessing plants’ natural ability to draw carbon dioxide out of the air by optimizing their root systems to store more carbon for … Read more

How light can vaporize water without the need for heat

How light can vaporize water without the need for heat

It’s the most fundamental of processes — the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation is all around us, and humans have been observing it and making use of it for … Read more

Modeling broader effects of wildfires in Siberia

Modeling broader effects of wildfires in Siberia

As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere. The global effects of increasing wildfires in Siberia have been modeled by researchers at Hokkaido University and colleagues at the University of Tokyo and Kyushu University. The … Read more

A chemical mystery solved — the reaction explaining large carbon sinks

A chemical mystery solved — the reaction explaining large carbon sinks

A mystery that has puzzled the scientific community for over 50 years has finally been solved. A team from Linköping University, Sweden, and Helmholtz Munich have discovered that a certain type of chemical reaction can explain why organic matter found in rivers and lakes is so resistant to degradation. Their study has been published in … Read more

Frog species evolved rapidly in response to road salts

Frog species evolved rapidly in response to road salts

When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a team led by Rick Relyea, Ph.D., professor of biological sciences and David M. Darrin ’40 Senior Endowed Chair at Rensselaer Polytechnic Institute, found a species of frog that has evolved over the … Read more
