Katherine Esau, born in 1898 in Ukraine, was a pioneering botanist who studied plant anatomy & viruses. Esau began studying agriculture in 1916 in Moscow. Her family fled to Berlin & ultimately arrived in the US in 1922. Esau earned a PhD & her research on plant structure spanned 7 decades. She wrote 6 textbooks & was the 6th woman elected to the National Academy of Sciences. In 1989, Esau received the National Medal of Science. https://ccber.ucsb.edu/ucsb-natural-history-collections-library-and-historical-information-katherine-esau/life-katherine #HistoryRemix #science #history

Scientists in China have found evidence that our ancestors were almost entirely wiped out ~1 million years ago. Why? #ClimateChange While not every expert agrees, the research is intriguing & @npub10mwv...xxep has the details:

Humanity’s Ancestors Nearly Died Out, Genetic Study Suggests (Published 2023)

The population crashed following climate change about 930,000 years ago, scientists concluded. Other experts aren’t convinced by the analysis.

Tardigrades have survived every mass extinction on Earth since they evolved about a 1/2 billion years ago.There are ~1,300 known species. And millions of years from now, they won’t even notice we’re gone. https://www.smithsonianmag.com/smart-news/tardigrades-turn-out-not-be-dna-thieves-180964236/ #nature Image: Eye of Science/Science Photo Library

My sweet pup's having surgery right now. I wish we could have more time with our #dogs. We really don't deserve them.

Globally we produce A LOT of #energy, but did you know the majority of fossil energy gets wasted? In the US alone, two-thirds of that energy is *wasted* as heat. As Hannah Ritchie has pointed out, we don’t actually need to produce a low carbon equivalent of all of the coal, oil & gas we currently use. That means we can decarbonize quickly by being less wasteful & more efficient. #ClimateChange #science

In my opinion, Earth is better with emperor penguins on it. So I truly hope we do all we can to prevent their extinction. #ClimateChange #nature

Climate change: Thousands of penguins die in Antarctic ice breakup

Vast numbers of emperor penguin chicks drown as sea-ice melts and collapses underneath them.

We often think of #memes as popular photos, videos, or phrases online. 
 But the term “meme” was coined by evolutionary biologist Richard Dawkins to describe a behavior, style or idea as a unit of culture that can spread or disappear. From social movements to religion to Grumpy Cat.
 Even though most folks may not be aware of it, we’re sharing a popular concept from #science, every single day, across #socialmedia.
