Southwest Research Institute engineers have developed the next generation of clean diesel engine technology to reduce hazardous nitrogen oxides (NOx) and carbon dioxide emissions while minimizing fuel consumption. Working with regulatory agencies, vehicle manufacturers and suppliers, SwRI combined engine modifications with integrated aftertreatment technology and control strategies to reach near-zero emissions levels. SwRI developed the technology for the California Air Resources Board (CARB), a state organization charged with combatting air pollution.

“Through the continued efforts of a multidisciplinary team, SwRI has developed one of the most fuel-efficient, low-emission diesel engines in the world,” said SwRI Research Engineer Bryan Zavala, a member of the low NOx development t...

Giant planets in our solar system and circling other stars have exotic clouds unlike anything on Earth, and the gas giants orbiting close to their stars—so-called hot Jupiters—boast the most extreme.

A team of astronomers from the United States, Canada and the United Kingdom have now come up with a model that predicts which of the many types of proposed clouds, from sapphire to smoggy methane haze, to expect on hot Jupiters of different temperatures, up to thousands of degrees Kelvin.

Surprisingly, the most common type of cloud, expecte...

In a new study, researchers have discovered how the protein PP2A can inhibit tumor growth in mice. The protein turns off an enzyme that stimulates cell growth, thus inhibiting the development of cancer.

Proteins are found throughout our cells and regulate a lot of biological processes that are important forour survival. But some of them also regulate processes that can make us sick. Now, an international research team, with researchers from the University of Copenhagen at the forefront, has achieved a much better understanding of one such protein.

In a new study, the researchers discovered how the protei...

The 5G revolution has begun, and the first lines of phones that can access the next generation of wireless speeds have already hit the shelves. Researchers at The University of Texas at Austin and the University of Lille in France have built a new component that will more efficiently allow access to the highest 5G frequencies in a way that increases devices’ battery life and speeds up how quickly we can do things like stream high-definition media.

Smartphones are loaded with switches that perform a number of duties...
