When it comes to designing better gizmos, efficiency is the name of the game. Why have two separate components to do two separate tasks, if you can have one do both? We have a whole bird-killing metaphor about how great it is to be efficient.
Well, what’s good for the goose, it turns out, is also good
for the robot fish.
A team of engineers at Cornell and the University of Pennsylvania have created a soft fish-shap ...read more
The James Webb Space Telescope -- minus the telescope -- recently underwent another round of testing. (Credit: NASA/Chris Gunn)
The James Webb Space Telescope (JWST) is NASA’s long-planned – and long-delayed – successor to Hubble. But after a recent spate of testing to mimic the extremes of space, it’s looking like the telescope is still on track for its 2021 launch date.
The telescope itself, along with its instrumentation, passed many of its final tests last year ...read more

I don’t know who said “you are what you eat,” but it really doesn’t make sense. I am objectively not made of peanut butter and coffee, though I’m certain that would be my fate if the sentiment were true. That said, the general idea — that what we eat matters — seems to hold more and more weight as studies of our diet pile up. Now, researchers say there's yet another wrinkle to the question of what to eat, one rooted in ...read more
Wildfires blazing in Siberia, as seen by one of the Sentinel 2 satellites on June 11th. (Source: Copernicus Sentinel image data processed by Pierre Markuse)
I started writing this post last week after seeing the stunning satellite image above showing a blazing Siberian wildfire.
When I returned to finish the post today, I learned from a story in the Siberian Times that wildfires in this part of Russia's Sakha Republic are now threatening a spectacular landscape feature known among locals ...read more
A section of limestone riddled with burrows bored by a unique rock-eating shipworm. (Credit: Shipway et al 2019, Proc. R. Soc. B 20190434. http://dx.doi.org/10.1098/rspb.2019.0434)
What would a shipworm do if a shipworm didn't eat wood? The humble bivalve has long had outsized influence on both its environment and even the global economy. That's because, until now, every known species consumes wood, sometimes with destructive results.
A shipworm species new to science, however, tunnels th ...read more
