Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study published in the journal JGR Solid Earth, a group of scientists used deep learning to study a large set of a specific type of seismic wave. The analysis revealed six continuous bands of irregularities at the core-mantle boundary (CMB) that had previously appeared only as...

After reconnection, Lake Erie wetland logged 3.44 million fish detections

A restored 25-acre coastal wetland on the southern shore of western Lake Erie was used continuously by millions of aquatic animals after it was reconnected to nearby waterways, according to a four-year acoustic monitoring study led by researchers at the United States Geological Survey (USGS). The scientific assessment, published in the journal Aquatic Ecosystem Health & Management, tracked aquatic movement across 2,022 hours of high-resolution sonar monitoring between 2011 and 2014.

China’s ‘chemical trap’ targets seawater uranium, beats US benchmark 8-fold

Chinese researchers have developed a new material capable of extracting uranium from seawater at more than eight times the target rate previously set by the US department of energy, SCMP reported. This marsk a potential advancement in the global effort to tap the oceans as a vast source of nuclear fuel. The team from the Chinese Academy of Sciences in Qingdao recovered up to 50.4mg of uranium per gram of the material from natural seawater samples, compared with the US benchmark of 6mg per gram.
