California's August Complex largest fire in state's history

NOAA/NASA's Suomi NPP satellite captured another startling image of the August Complex of fires that has grown to over 1,000,000 acres burned (1,006,140 acres total) and because of that grim milestone the complex has been dubbed a "gigafire." The August Complex is only 58% contained. Inciweb reports that: "In the northeast zone, active behavior continues. Structures in Hidden Valley, Trinity Pines/Post Mountain, Wildwood and Platina are threatened by fire spread. Short range spotting and fire spread toward Hidden Valley has increased potential for impact to structures."

New study rebuts 75-year-old belief in reptile evolution

Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the stamps in Tiago R. Simões ' passport.

New 3-D model could explain the formation of a hexagon storm on Saturn

With its dazzling system of icy rings, Saturn has been a subject of fascination since ancient times. Even now the sixth planet from the sun holds many mysteries, partly because its distance away makes direct observation difficult and partly because this gas giant (which is multiple times the size of our planet) has a composition and atmosphere, mostly hydrogen and helium, so unlike that of Earth. Learning more about it could yield some insights into the creation of the solar system itself.

Fighting pandemics with plasma

Most types of personal protective equipment, like N95 masks, gowns, and gloves, are designed for single use, which has led to both scarcity and waste during the COVID-19 pandemic. But new research suggests these vital supplies can be safely disinfected and reused.

Plasma scientists optimize plant growth and yield

Ever since scientists discovered that plasma treatment leads to faster growth and higher yields of some agricultural crops, physicists, chemists, and biologists have been working together to tease out the mechanisms driving this phenomenon.

This 'squidbot' jets around and takes pics of coral and fish

Engineers at the University of California San Diego have built a squid-like robot that can swim untethered, propelling itself by generating jets of water. The robot carries its own power source inside its body. It can also carry a sensor, such as a camera, for underwater exploration.

Applying artificial intelligence to science education

A new review published in the Journal of Research in Science Teaching highlights the potential of machine learning—a subset of artificial intelligence—in science education. Although the authors initiated their review before the COVID-19 outbreak, the pandemic highlights the need to examine cutting-edge digital technologies as we re-think the future of teaching and learning.
