If you summitted the Andes 20 million years ago, you might have looked out on a glinting inland sea, big enough to sail from Paraguay to Venezuela. I wrote about that waterway and the #forest #biodiversity that may be its legacy. pnas.org/content/118/10… #Miocene #Amazon PNASNews

An electronic skin that wraps around a #robot’s finger can detect pressure, friction, and strain. This is the first time that researchers have arranged a mix of #sensors in complex 3D layouts similar to those of sensory cells in human skin. #ElectronicSkin pnas.org/post/journal-c…

At just 4 weeks, a human #embryo begins to grow arms and legs. The gene #TBX3 plays a key role in establishing the #AnteriorPosteriorAxis of the limb responsible for the formation of the thumb on the front side and the pinkie on the back side. #BirthDefect pnas.org/post/journal-c…

Thank you to Amy McDermott for writing a nice piece for the Front Matter section of PNAS on our recent paper by Geoffrey Soussi et al. The gene TBX3 plays a critical role in early limb formation | Journal Club | PNAS pnas.org/post/journal-c…

FROG SAUNA is the only cover i want to see today

One gene family is consistently duplicated across #ResurrectionPlants, which adapted to survive #drought by completely drying out, down to less than 10% water in their tissues. The genetic duplications hint at an underlying mechanism for the #adaptation. pnas.org/post/journal-c…

NOOO! What a gut punch. Sadly, Hakai Magazine will be shuttering at the end of this year because of a lack of funding. I’ve loved the community and writing for and reading the magazine, and I’m hoping it can continue in some form.

The rocky walls of #volcanoes are studded with crystals, formed underground in hot #magma. By studying how long the #crystals take to form, #volcanologists are calibrating #CrystalClocks that reveal how long magmas can linger below ground before erupting. pnas.org/doi/10.1073/pn…

Hey #ESA2024 anyone wanna check out the #GrunionRun? We're here right around the new moon, so may spot one of the most iconic SoCal marine ecological phenomena. Grunion fish should come up on the sand around 11pm this week, you just never know what beach. wildlife.ca.gov/Fishing/Ocean/…

Professor Maulik Jagnani spoke to Amy McDermott of PNASNews about his new study, which examines sleep and education outcomes in India. pnas.org/post/journal-c…

Join me on an expedition into the #CloudForest, to unpack research on the delicate plants carpeting the canopy. They're canaries in the coal mine of #ClimateChange and may hold clues for impending change to the forest water cycle. Pulitzer Center PNASNews pnas.org/doi/10.1073/pn…

It's OFFICIAL. Hakai Magazine will continue; not in name, but in spirit. In January 2025, senior staff from Hakai will be joining bioGraphic magazine biographic.com That means more awesome narrative features and science-based news. But, of course, WE NEED YOUR HELP

How can people live alongside the growing reality of #wildfire? One approach: likening fires to other natural hazards, like hurricanes or tornadoes. Communities can’t stop these forces of nature. But they can design around them. From PNASNews pnas.org/doi/10.1073/pn…

A study in the pond-dwelling cousin of the #BrainEatingAmoeba finds that a cell's #microtubules can be tailored to different functions by its component tubulins. In PNASNews. #amoeba #proteins #cellbio pnas.org/post/journal-c…

Feral sheep roam Hirta, a rugged and windswept island far off the #Scottish coast. This short video unpacks new research, finding that long-term success for the #sheep hinges on the first year of life—especially for males. #Ecology tiktok.com/@amy_g_mcd/vid…

The practice of killing animals to manage populations is called "lethal control." Think: western coyote culls, or barred owls in the Pacific Northwest. But what does the science say about killing as a management tool? Does it work? PNASNews investigates. pnas.org/doi/10.1073/pn…

In the ocean, baby #fish can drift thousands of miles on currents. How far they go, and where they end up are ongoing mysteries in #MarineEcology. Our latest PNASNews feature story unpacks the research on this phenomenon, called #PelagicLarvalDispersal. pnas.org/doi/10.1073/pn…
