In the world of climate science — and science in general — data is king. The more of it you have, and the higher its quality, the better. And while such trends as the rise in temperatures and sea levels have impeccable data behind them, not every measure of a changing climate has been so lucky.
Take the global wind and wave climate, for example, which measures trends in wind speed and wave height in oceans around the globe. Both of these factors affect the interplay between the atmo ...read more
When researchers with the Event Horizon Telescope (EHT) unveiled the first true picture of a black hole on April 10, they finally succeeded in imaging the invisible. The bright ring of the accretion disk and the dark shadow of the event horizon stood out clearly, validating scientists’ theories as to what a singularity looked like.
The event was a momentous one for the space artists who have spent decades drawing black holes in the absence of actual confirmation of what they look like. We ...read more
Most people would think that it would be hard to hide the evidence of a massive volcanic eruption. It shouldn't be hard to track down the source of tens of cubic kilometers of ash and debris because it should just get thicker and thicker until you reach the volcano that disgorged the mess. Yet, somehow, it isn't that easy. We live on a geologically active planet where all the processes of weather, tectonics, volcanism and more can quickly disassemble the deposits of an eruption -- even a gia ...read more
When navigating through dark environments, rats swish their whiskers against nearby objects to figure out where they are. As the animals explore, they use this sense of touch to build maps of unfamiliar places. Cockroaches and blind crayfish use their antennae in a similar approach.
Now, the go-by-feel strategy has inspired the creation of a robotic catheter capable of finding its way through the beating heart of lives pigs during a surgical procedure without the help of a surgeon’s guidi ...read more
Charred earth, shells, bones and human burials found in mounds on a plain in northern Bolivia are offering scientists new clues about the earliest known inhabitants of the southwestern Amazon.
The remains, excavated from raised areas known as “forest islands” on the Llanos de Moxos, an extensive savanna, show the area was inhabited between 10,600 and 4,000 years ago, according to new study published Wednesday in the journal Science Advances.
“In the late Holocene, about 2,500 ...read more
