A three-step chemical process could successfully recover high-purity silicon from recycled photovoltaic (PV) solar panels, new tests show. The scientists behind the research say that recycling not only helps the PV industry meet regulatory requirements, but also reduces pressure on demand for raw materials.

A team of Carnegie scientists has discovered three giant planets in a binary star system composed of stellar ''twins'' that are also effectively siblings of our Sun. One star hosts two planets and the other hosts the third. The system represents the smallest-separation binary in which both stars host planets that has ever been observed. The findings, which may help explain the influence that giant planets like Jupiter have over a solar system's architecture, have been accepted for publication in The Astronomical Journal.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.)

When natural disasters, such as earthquakes, storms and hurricanes, are reported in the media, they are often accompanied by an assessment of the cost of the disaster. While such information can be useful to help governments and international organisations target aid and recovery efforts, the details of what is included in the assessment, and the methods used, are often unclear.

The environmental and economic costs of a selection of common crops have been determined by a new study, which hopes to improve agricultural sustainability assessments in Europe. The researchers used life cycle analysis on organically farmed tomatoes and pears, and intensively farmed wheat, apples, and lettuce to show the overall impact of agricultural methods.

In this brave new world, an IP that can help a business quickly adapt to remote working conditions, provide reliable and safe supply chain, and safeguard security, will become the game-changer for businesses to survive and even thrive.

Acidification of water bodies can have substantial impacts on aquatic wildlife, and even after chemical conditions improve, biological recovery may lag behind. A study of Swedish lakes shows that, although their chemical quality has improved as a result of international reductions of acidifying emissions, biological recovery has been much slower in some lakes.

The EU would not be breaking World Trade Organization (WTO) rules if it chose to extend REACH’s authorisation scheme on substances of very high concern (SVHC) to products imported to Europe, a recent legal analysis concludes. At present, the scheme — which is effectively a ban on SVHC, with some exceptions — applies only to products made within the European Economic Area (EEA).
