Here’s the summer science you might have missed
From sizzling Siberia and ‘smart’ toilets, to new uses for astronaut pee, more than COVID-19 made news this summer.
- Microbes
Some deep-seafloor microbes still alive after 100 million years!
Some starving microbes nap while awaiting their next meal. For some living miles below the ocean surface, that nap may exceed 100 million years.

Busy beavers may be speeding thaw of Arctic permafrost
As climate change continues, busy beavers are expanding their range in Alaska. Their dams could further speed the loss of permafrost there and promote local warming.

Dust can infect animals with flu, raising coronavirus concerns
Dust particles kicked up from some virus-contaminated surface can become a source of new infections, rodent data show.
- Agriculture
Scientists Say: Carbohydrate
Carbohydrates are molecules with carbon, oxygen and hydrogen. Animals break down these chemicals in food to get energy.
- Space
Scientists Say: Solar
What do solar energy, the solar year and solar flares have in common? They’re all related to the sun.

Pesticides contaminate most food of western U.S. monarchs
Monarch caterpillars eat only milkweeds. A new study finds widespread pesticide use has tainted these plants across the insect’s western U.S. breeding grounds.

Siberian heat wave that caused an oil spill made more likely by climate change
The six-month heat wave in Siberia during the first half of 2020 would not have happened without human-caused climate change, researchers find.

- Ecosystems
Scientists Say: Deforestation
Trees slurp up carbon dioxide and help keep our planet cool. But deforestation cuts those trees down in large numbers.
