“Missing Link” Uncovered: The Secret History of Corn Revealed Through RNA

Posted by in categories: biological, food, genetics

Researchers at Cold Spring Harbor Laboratory have traced the domestication of maize back to its origins 9,000 years ago, highlighting its crossbreeding with teosinte mexicana for cold adaptability.

The discovery of a genetic mechanism known as Teosinte Pollen Drive by Professor Rob Martienssen provides a critical link in understanding maize’s rapid adaptation and distribution across America, shedding light on evolutionary processes and potential agricultural applications.

Cold Spring Harbor Laboratory (CSHL) scientists have begun to unravel a mystery millennia in the making. Our story begins 9,000 years ago. It was then that maize was first domesticated in the Mexican lowlands. Some 5,000 years later, the crop crossed with a species from the Mexican highlands called teosinte mexicana. This resulted in cold adaptability. From here, corn spread across the continent, giving rise to the vegetable that is now such a big part of our diets. But how did it adapt so quickly? What biological mechanisms allowed the highland crop’s traits to take hold? Today, a potential answer emerges.

Missing Link Discovered: New Research Paves the Way for Charging Phones in Under a Minute

Posted by in categories: biological, chemistry, computing, engineering, mobile phones, particle physics, sustainability, transportation

CU Boulder scientists have found how ions move in tiny pores, potentially improving energy storage in devices like supercapacitors. Their research updates Kirchhoff’s law, with significant implications for energy storage in vehicles and power grids.

Imagine if your dead laptop or phone could be charged in a minute, or if an electric car could be fully powered in just 10 minutes. While this isn’t possible yet, new research by a team of scientists at CU Boulder could potentially make these advances a reality.

Published in the Proceedings of the National Academy of Sciences, researchers in Ankur Gupta’s lab discovered how tiny charged particles, called ions, move within a complex network of minuscule pores. The breakthrough could lead to the development of more efficient energy storage devices, such as supercapacitors, said Gupta, an assistant professor of chemical and biological engineering.

Electron Dynamics Redefined Through Super-Bloch Oscillations

Posted by in categories: physics, transportation

Researchers achieve advances in periodic oscillations and transportation for optical pulses, with potential for next-gen optical communications and signal processing.

Researchers have achieved significant advances in wave physics by conducting experiments on Super-Bloch Oscillations (SBOs), which demonstrate the potential for manipulating optical pulses. By applying both DC and nearly detuned AC electric fields, they not only observed SBO collapse for the first time but also extended these oscillations to arbitrary wave driving situations, paving the way for innovative optical communication technologies.

Revolutionary GPS Method Reveals Earth’s Crust Movements Post-Earthquake

Posted by in categories: evolution, innovation

A groundbreaking study using sub-daily GPS has improved our understanding of early afterslip following earthquakes, offering a more accurate assessment of seismic hazards and enhancing emergency response and preparedness strategies.

A groundbreaking study has revealed new insights into the Earth’s crust’s immediate behavior following earthquakes. Researchers have utilized sub-daily Global Positioning System (GPS) solutions to accurately measure the spatial and temporal evolution of early afterslip following the 2010 Mw 8.8 Maule earthquake. This innovative approach marks a significant advancement in seismic analysis, offering a more precise and rapid depiction of ground deformations, which is essential for assessing seismic hazards and understanding fault line activities.

The aftermath of an earthquake is marked by intricate postseismic adjustments, particularly the elusive early afterslip. Daily seismic monitoring has struggled to capture the rapid and complex ground movements occurring in the critical hours post-quake. The intricacies of these initial activities and their profound implications for seismic hazard assessment highlight an urgent need for more refined and immediate monitoring techniques.

“The moment when we wrote down the terms of this equation and saw that it all clicked together, it felt pretty incredible,” Wordsworth said. “It’s a result that finally shows us how directly the quantum mechanics links to the bigger picture.”

In some ways, he said, the calculation helps us understand climate change better than any computer model. “It just seems to be a fundamentally important thing to be able to say in a field that we can show from basic principles where everything comes from.”
