When The Secret Life of Plants came out in 1973, Lincoln Taiz was a graduate student, just embarking on what would become a many-decades long career in plant biology. Plants, the book revealed, can make their own trace elements through fusion, just like the sun. More, they can recognize people. If someo ...read more
At 3.8 million years old, this mostly complete cranium of Australopithecus amanensis is the oldest australopith skull in the fossil record. (Credit: Dale Omori, courtesy of the Cleveland Museum of Natural History)
On Feb. 10, 2016, the face of a ghost emerged from weathered Ethiopian sandstone. The nearly complete skull, 3.8 million years old, was found less than 20 miles from the site where Lucy, the most famous of our distant evolutionary relatives, was discovered in the 1970s.
Lucy was ...read more
Gas glows white, lit by a stellar nursery, in this view of a region within the Large Magellanic Cloud, the Milky Way’s largest satellite galaxy. Most cosmic gas is not so visible and lies outside of galaxies — in halos surrounding galaxies and in the vast spaces in between. Yet the gas determines galactic life cycles.

Most of what astronomers know about the universe comes from what they can see. So their ideas have been prejudiced toward stars and g ...read more
An albino lizard hatchling, one of the first to be gene edited with CRISPR. (Doug Menke)
Skittering among the Caribbean flora are anole lizards, tiny reptiles no bigger than a finger’s length. Sporting shades of grey, brown and green, island life has spurred the evolution of some 150 species there.
As a result, anole lizards have become a key scientific model for research into how reptiles develop and evolve. But scientists have been missing a critical element: the tools to investig ...read more

So, first off, I apologize for the clickbait headline, but don't worry, there actually is a payoff here. What I'm going to say is 100% true. Geology isn't just a pile of rocks, no matter what you might think. Sure, there are rocks involved ... but "geo" doesn't mean rocks. It means Earth, so when we talk about geology, we're talking about the our planet -- and our planet is mo ...read more

A SpaceX Dragon cargo spacecraft will return to Earth on August 27, bringing back experiments from the International Space Station (ISS), including investigations into how moss grows in space.
The capsule originally launched July 25 from Cape Canaveral on a SpaceX Falcon 9 rocket, taking two days to reach the ISS. It successfully completed its cargo resupply mission and has been do ...read more

(Inside Science) -- Extinction wiped out their closest family members as well as most of the ancient reptiles of comparable size. But the largest lizards still on the planet, the Komodo dragon, survived due to a lucky combination of mediocre habitat on their home islands and unintended human interventions.
“You would have thought the Komodo would have been wiped out, and yet it survived,” said Rick Shine, a biologist at Macquarie University in Sydn ...read more

Want to live forever? Or at least well into old age? Results from a new study suggest optimism might be part of the equation. A large-scale study indicates those with a bright outlook on life lived as much as 10 percent longer, and stood a better chance of making it past 85.
"This study ... suggests that optimism is one such psychosocial asset that has the potential to extend the human lifespan,” Boston University School of Medicine clinical research psyc ...read more

Around the world, humans communicate with each other using nearly 7,000 distinct languages. But despite how different languages like English and Chinese are for example, we all use the same basic anatomy to talk. Our lips, tongues and the bones inside our mouths allow humans to make the noises of language.
Now researchers have found that differences in the shape of the roof of the mouth influence how we pronounce vowel sounds. And the team says that these mi ...read more
