Making a living raising cattle isn’t as simple as just buying a herd and turning it out to pasture. Cattle require specific diets to maintain proper nutrition and weight gain. And how to do this in the most effective and efficient way possible has interested both ranchers and researchers for generations.

Scientists from Tomsk Polytechnic University are developing a technology for fuel production from coal processing wastes. This fuel is ten times more environmentally friendly that will make it possible to resolve two problems at once: to reduce the amount of anthropogenic emissions of TPSs and efficiently dispose wastes from coal processing and beneficiation. The research team of the Department of Automation of Thermal Power Processes led by Professor Pavel Strizhak shares its outcomes.

A new advance on a method developed by MIT researchers could enable continuous, high-precision monitoring of materials exposed to a high-radiation environment. The method may allow these materials to remain in place much longer, eliminating the need for preventive replacement. It could also speed up the search for new, improved materials for these harsh environments.

The new findings appear in the journal Applied Physics Letters, in a paper by graduate student Cody Dennett and assistant professor of nuclear science and engineering Michael Short. This study builds on the team’s earlier work that described the benchmarking of the method, called transient grating spectroscopy (TGS), for nuclear materials. The new research shows that the technique can indeed perform with the high degree of sensitivity and time-resolution that the earlier calculations and tests had suggested should be possible for detecting tiny imperfections.

A novel molybdenum-coated catalyst that can efficiently split water in acidic electrolytes is developed by researchers at KAUST and could help with efficient production of hydrogen.

Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22% power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have been achieved. EPFL scientists have now built a low-cost, ultra-stable perovskite solar cell that has operated for more than a year without loss in performance (11.2%). The work is published in Nature Communications.

While bidets remain unpopular in America, they’re a familiar fixture in bathrooms all over the world. And they raise an inevitable question: Is it better for the environment if you wipe, or should you wash instead?

The answer may surprise you — and could lead you to rethink your next bathroom remodel.

When first responders arrived to the burning home on Eugene Street in Manchester, New Hampshire just after 2 am on January 27, half the home was already up in flames. It was a big fire, but relatively routine: Working in the dark, the firefighters made sure the two residents got out unharmed, and got to work.

Just as Cinderella turned from a poor teenager into a magnificent princess with the aid of a little magic, scientists at the U.S. Department of Energy’s Argonne National Laboratory have transformed a common metal into a useful catalyst for a wide class of reactions, a role formerly reserved for expensive precious metals.

In a new study, Argonne chemist Max Delferro boosted and analyzed the unprecedented catalytic activity of an element called vanadium for hydrogenation – a reaction that is used for making everything from vegetable oils to petrochemical products to vitamins. 

Not long ago in the southwest of England, a local community set out to replace a 1960s-vintage school with a new building using triple-pane windows and super-insulated walls to achieve the highest possible energy efficiency. The new school proudly opened on the same site as the old one, with the same number of students, and the same head person—and was soon burning more energy in a month than the old building had in a year.

Some coastal residents might describe Fowler, California, as the middle of nowhere. But it’s smack in the center of the San Joaquin Valley, a region critical for growing food for the rest of the state and much of the U.S. Like much of the Valley, this town of 5,500 people, located a 15-minute drive south of Fresno, struggles with terrible air quality. But a growing movement may soon change that.
