Life-cycle greenhouse gas emissions of biomethane and hydrogen pathways in the European Union

A new life-cycle analysis of potentially low-greenhouse-gas options for producing hydrogen in Europe finds that only hydrogen produced using renewable electricity can be effectively zero-emission, and that hydrogen pathways involving fossil fuels, even with carbon capture and storage, have greenhouse-gas (GHG) intensity high enough to make it unlikely they can contribute to meeting the European Union's climate targets. The study, from the International Council on Clean Transportation (ICCT), also found that waste-based biomethane production pathways generally have negative GHG intensity, but are subject to significant uncertainties.

Study asserts that assessments of parolees' risk should consider recidivism-free time

As efforts to reverse mass incarceration rise, so does the need to supervise more individuals in the community. Faced with heightened demand, corrections agencies increasingly use risk assessment to allocate supervision and treatment resources efficiently and improve public safety. A new study examined the time individuals have spent without being arrested or returning to prison, looking at the relation between recidivism-free time in a community and recidivism among individuals on parole supervision in Pennsylvania. The study concludes that those assessing parolees' risk should incorporate information about recidivism-free time.

Surface chemistry reveals corrosive secrets

One can easily see with the naked eye that leaving an old nail out in the rain causes rust. What does require the keen eyes and sensitive nose of microscopy and spectroscopy is observing how iron corrodes and forms new minerals, especially in water with a pinch of sodium and calcium.

Chemists' dye method holds promise for long-term data storage

In the digital age, every byte of data needs to go somewhere—and preferably stay there a long time. That last part is a major problem when it comes to data-storage systems, which typically last less than 20 years. A group of Harvard chemists is trying to solve the issue with an innovation that resembles tiny drops of ink.

Improved fluorescent amino acids for cellular imaging

New research conducted by researchers in the lab of Penn's E. James Petersson in collaboration with Oregon State University and the University of Washington describes how proteins in living cells can be engineered to include synthetic fluorescent amino acids that are bright, long-lasting, and have properties that sense their environment. This work can help biologists study proteins more easily, with implications for understanding the mechanisms of complex neurological diseases. The results were published in Chemical Science with two associated studies published in eLife and Scientific Reports.

Did a black hole eating a star generate a neutrino? Unlikely, new study shows

In October 2019, a high-energy neutrino slammed into Antarctica. The neutrino, which was remarkably hard to detect, peaked astronomers' interest: what could generate such a powerful particle?
