New approach to removing toxins from wastewater

The New York State Center for Clean Water Technology (CCWT) at Stony Brook University has made a series of critical discoveries regarding a new approach to protecting Long Island's drinking water, groundwater, and surface waters. Some of the discoveries involve the likely human carcinogen, 1,4-dioxane, which has been found at higher levels in Long Island drinking water than anywhere else in the U.S.

New light shed on the early evolution of limb bone marrow

When and how bone marrow first originated in the limbs of early four-legged animals is disputed in evolutionary biology. With the help of powerful X-ray technology, an international research team, led by Uppsala University, has now discovered that this evolutionary adaptation most likely took place after the first tetrapods stepped ashore.

Ice Age testing reveals challenges in climate model sensitivity

Key to the usefulness of climate models as tools for both scientists and policymakers is the models' ability to connect changes in atmospheric greenhouse gas levels to corresponding shifts in temperature. Equilibrium climate sensitivity (ECS) is one such measure, representing the predicted warming after a doubling of atmospheric carbon dioxide (CO2) levels.

Optimizing disinfection to prevent spread of antibiotic resistance in wastewater

For nearly a century, improvement in human healthcare has depended heavily on the efficiency with which we can treat bacterial diseases. But today, antibiotic resistance—the ability of certain mutant super-bacteria to block out antibiotics—poses a major threat to healthcare, food security and overall social development worldwide, threatening to upend much medical progress.

Plastic solar cells combine high-speed optical communication with indoor energy harvesting

Around the world, there are currently more than 18 billion internet-connected mobile devices. In the next 10 years, anticipated growth in the internet of Things (IoT) and in machine-type communication in general, will lead to a world of hundreds of billions of data-connected objects. Such growth poses two very challenging problems:

How 'green' are environmentally friendly fireworks?

Fireworks are used in celebrations around the world, including Independence Day in the U.S., the Lantern Festival in China and the Diwali Festival in India. However, the popular pyrotechnic displays emit large amounts of pollutants into the atmosphere, sometimes causing severe air pollution. Now, researchers reporting in ACS' Environmental Science & Technology have estimated that, although so-called environmentally friendly fireworks emit 15-65% less particulate matter than traditional fireworks, they still significantly deteriorate air quality.

Examining the environmental impact of computation and the future of green computing

When you think about your carbon footprint, what comes to mind? Driving and flying, probably. Perhaps home energy consumption or those daily Amazon deliveries. But what about watching Netflix or having Zoom meetings? Ever thought about the carbon footprint of the silicon chips inside your phone, smartwatch or the countless other devices inside your home?

Cooperative eco-driving automation improves energy efficiency and safety

Imagine you're driving up a hill toward a traffic light. The light is still green so you're tempted to accelerate to make it through the intersection before the light changes. Then, a device in your car receives a signal from the controller mounted on the intersection alerting you that the light will change in two seconds—clearly not enough time to beat the light. You take your foot off the gas pedal and decelerate, saving on fuel. You feel safer, too, knowing you didn't run a red light and potentially cause a collision in the intersection.
