New Material Could Aid in Nuclear Nonproliferation
A newly discovered quasicrystal that was created by the first nuclear explosion at Trinity Site, N.M., on July 16, 1945, could someday help scientists better understand illicit nuclear explosions and curb nuclear proliferation. The newly discovered material was formed accidentally in the blast of the first atomic bomb test, which resulted in the fusion of surrounding sand, the test tower, and copper transmission lines into a glassy material known as trinitite.

New Replication Crisis: Research Which Is Less Likely to Be True Is Cited More
Papers in leading psychology, economic and science journals that fail to replicate and therefore are less likely to be true are often the most cited papers in academic research, according to a new study. The study explores the ongoing “replication crisis” in which researchers have discovered that many findings in the fields of social sciences and medicine don’t hold up when other researchers try to repeat the experiments.

Previously Unrecognized Tsunami Hazard to Coastal Cities Identified
A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay Area, Izmit Bay in Turkey and the Gulf of Aqaba in Egypt.

Shape-Shifting Computer Chip Thwarts an Army of Hackers
A processor is the piece of computer hardware that runs software programs. Since a processor underlies all software systems, a secure processor has the potential to protect any software running on it from attack. We have developed and tested a secure new computer processor that thwarts hackers by randomly changing its underlying structure, thus making it virtually impossible to hack.

Rare Earth Supply Disruptions Have Long-Range Impacts
Rare earth materials are essential to a variety of industries. From phones to fighter jets, a range of devices and machines rely on rare earth elements that are mined and refined largely in China. Disruptions to this supply can have wide-ranging consequences, but the understanding of how those disruptions play out in global markets is limited. A new study from explores the effects of supply disruptions such as mine shutdowns.

Solar Geoengineering May Alleviate Impacts of Global Warming on Crops
Solar geoengineering — putting aerosols into the atmosphere to reflect sunlight and reduce global warming — is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture.

Engineers and Economists Prize Efficiency, but Nature Favors Resilience – Lessons from Texas, COVID-19 and the 737 Max
The damage from Winter Storm Uri, the economic devastation from the COVID-19 pandemic and the fatal Boeing 737 Max accidents show the price society pays for a relentless pursuit of efficiency. Modern society has prioritized free-market economics and efficient computer systems to the detriment of other priorities. Studies of algorithms show that efficiency can come at a high cost. Sexual reproduction and car insurance highlight the benefits of resilience.

“Viable but Narrow” Pathway to Zero Carbon Emissions by 2050: IEA
The world has a viable pathway to building a global energy sector with net-zero emissions in 2050, but it is narrow and requires an unprecedented transformation of how energy is produced, transported and used globally, the International Energy Agency said in a landmark special report released Tuesday.

The U.S. Is Trying to Reclaim Its Rare-Earth Mantle
Rare earths elements (REEs) are used in cancer treatment and electric engines, telescope lenses and TVs, cellphones and fighter jets. Many REEs are extracted and refined almost entirely in China. The U.S. was 100% net import reliant on rare-earth elements in 2018, importing an estimated 11,130 metric tons of compounds and metals valued at $160 million. The Department of Energy is funding research to make separating rare earths easier and more efficient, and to promote recycling. “There is a clock ticking in the background of this race for a rare-earth supply chain. There is a danger that the electric vehicle market, which will demand large quantities of critical minerals including rare earths, may move faster than the rare-earth supply chain, which would feed it,” Sabri Ben-Achour writes.

Hydropower’s Evolving Value to the Grid and Energy Storage
Across the United States, hydroelectric dams are capturing energy from river water to create electricity that powers everything from street lights to mega industrial plants. Hydropower represents 41 percent of all renewable energy generated across the nation and is a key element of a flexible, resilient electric grid. But in some parts of the country, operations at dams are changing.
