New algorithm sharpens focus of world's most powerful microscopes

We've all seen that moment in a cop TV show where a detective is reviewing grainy, low-resolution security footage, spots a person of interest on the tape, and nonchalantly asks a CSI technician to "enhance that." A few keyboard clicks later, and voila—they've got a perfect, clear picture of the suspect's face. This, of course, does not work in the real world, as many film critics and people on the internet like to point out.

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 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.

Study finds odor-sensing neuron regeneration process is adaptive

Olfactory sensory neurons are nasal neurons that make use of hundreds of different types of odorant receptors to analyze odorous chemicals in our external world and send that information to our brain. These neurons have the unusual ability to undergo turnover throughout life—a process understood to happen due to the special vulnerability of these neurons to environmental insults, such as viruses.

Seeking ancient rainforests through modern mammal diets

Closed-canopy rainforests are a vital part of the Earth's modern ecosystems, but tropical plants don't preserve well in the fossil record so it is difficult to tell how long these habitats have existed and where rainforests might have once grown. Instead, scientists look to the diets of extinct animals, which lock evidence of the vegetation they ate into their teeth. A new study led by scientists at the American Museum of Natural History finds that the paradigm used to identify closed-canopy rainforests through dietary signatures needs to be reassessed. The findings are published this week in the journal Proceedings of the National Academy of Sciences.

As pandemic affects children's health, programs that work are still underused

The coronavirus (COVID-19) pandemic has caused widespread harm to the health and well-being of already vulnerable children and adolescents in the U.S., particularly those in low-income households and children of color. Nevertheless, evidence-based programs known to reverse the negative effects of poverty are being widely neglected, according to a new report in Health Affairs. Such programs include basic income supports, other family supports, and universal health care structured to meet family needs. A combination of these interventions could substantially reduce the risks children face from poverty and early adversity, say the authors.
