Do Animals Really Anticipate Earthquakes? Sensors Hint They Do
An anonymous reader quotes Scientific American:
For centuries, people have described unusual animal behavior just ahead of seismic events: dogs barking incessantly, cows halting their milk, toads leaping from ponds… Now researchers at the Max Planck Institute of Animal Behavior and the University of Konstanz, both in Germany, along with a multinational team of colleagues, say they have managed to precisely measure…
New Imaging System Creates Pictures By Measuring Time
An anonymous reader writes: Photos and videos are usually produced by capturing photons — the building blocks of light—with digital sensors. For instance, digital cameras consist of millions of pixels that form images by detecting the intensity and color of the light at every point of space. 3-D images can then be generated either by positioning two or more cameras around…
Scientists make quantum technology smaller
A way of shrinking the devices used in quantum sensing systems has been developed by researchers at the UK Quantum Technology Hub Sensors and Timing, which is led by the University of Birmingham. …
Human-linked Earth vibrations dropped 50% during Covid-19 lockdown
Between March and May 2020, many people across Earth went into lockdown. During those months, seismographs recorded a drop in human-linked vibrations in the solid Earth, by an average of 50%.

U.S. Hatches Plan To Build a Quantum Internet That Might Be ‘Unhackable’
U.S. officials and scientists unveiled a plan this week to pursue what they called one of the most important technological frontiers of the 21st century: building a quantum Internet. From a report: Speaking in Chicago, one of the main hubs of the work, they set goals for forging what they called a second Internet — one that would function alongside the…
The Entire World’s Carbon Emissions Will Finally Be Trackable In Real Time
An anonymous reader quotes a report from Vox: There’s an old truism in the business world: what gets measured gets managed. One of the challenges in managing the greenhouse gas emissions warming the atmosphere is that they aren’t measured very well. The ultimate solution to this problem– the killer app, as it were — would be real-time tracking of all global…
