41 large polluters to get free passes in Washington state carbon trading market

Credit: CC0 Public Domain Washington is required by law to eliminate or offset all of its greenhouse gas emissions by 2050. But generous exemptions for more than 40 of the state’s biggest polluters in a forthcoming carbon market could push that goal beyond reach. In January, the state Department of Ecology will roll out a … Read more

Toward sustained, stable Raman imaging of large samples at the nanoscale

Conventional nanoscale imaging is usually difficult to perform for large, micron-scale samples owing to drifts caused by thermal effects and vibrations. Now, researchers from Japan address this issue with a newly developed imaging system that compensates for such drifts. Credit: Professor Prabhat Verma from Osaka University Raman spectroscopy, an optical microscopy technique, is a non-destructive … Read more

The Large Hadron Collider returns in the hunt for new physics

Ready, steady, go: the race to discover new physics returns today as the Large Hadron Collider (LHC) is re-ignited, firing heavy ion particles into one another at 99.99% the speed of light to recreate a state of primordial matter not seen since just after the Big Bang. The Large Hadron Collider is the world’s longest … Read more

ALMA observes ongoing star-formation standoff in the Large Magellanic Cloud

30 Doradus is a large star-forming region located in the heart of the Tarantula Nebula. Shown here in composite, the red/orange millimeter-wavelength data from the Atacama Large Millimeter/submillimeter Array (ALMA) stands out like stringlike filaments against optical data from the Hubble Space Telescope (HST). Scientists studying 30 Dor discovered that despite intense stellar feedback— which … Read more

Australia is investigating a digital currency, or e-dollar, but its benefits seem slight and the risks to privacy are large

Credit: Shutterstock We are used to thinking of money as notes and coins, the kind most of us hold in our wallets. But the most money—in Australia it’s 96.3%—is digital, held by financial institutions and moved around via bank transfers, debit cards and credit cards. Late last year Treasurer Josh Frydenberg promised to consult about … Read more

Effects of Large Satellite Constellations on Astronomy – Explaining Science

Many of you will have seen the images back in 2019 which showed long ‘trains’ composed of up to sixty SpaceX Starlink satellites crossing the sky in a straight line. These pictures hit the headlines not only because of the number of satellites, but because of their brightness. A ‘train’ of SpaceX Starlink satellites, the … Read more
