This week, astronauts and scientists are venturing under the sea as part of NEEMO-23, the 23rd expedition of the NASA’s Extreme Environment Mission Operations. NEEMO sends specialists to Aquarius, an underwater research station located 3.5 miles off the coast of Key Largo in Florida, and 62 feet under the surface.
Thanks to the buoyancy of seawater and the sandy seafloor,
the area around Aquarius is a ...read more

The real impact of climate change depends on tiny organisms we can’t even see, argues an international panel of more than 30 microbiologists in a consensus statement published Tuesday.
Microbes, or microorganisms, are any organism or virus invisible to the naked eye. Numbering in the nonillions (in the U.S., that’s 10,0 ...read more

When it comes to medical diagnoses, Alzheimer’s is a grim one. Those who develop the disease, which causes ever-worsening memory and behavioral problems, don’t have many treatment options. There are a handful of drugs that can ease symptoms, but none of them slow down the disease’s progression or offer a cure. But one approach, outside the realm of drugs and medications, is quickly showing some strong potential for treatment -- fasting.

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 (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
