If temperature varies strongly from day to day, the economy grows less. Through these seemingly small variations climate change may have strong effects on economic growth. This shows data analyzed by researchers from the Potsdam Institute for Climate Impact Research (PIK), Columbia University and the Mercator Research Institute on Global Commons and Climate Change (MCC). In a new study in Nature Climate Change, they juxtapose observed daily temperature changes with economic data from more than 1,500 regions worldwide over 40 years - with startling results. "We ...

Negishi cross-coupling reactions have been widely used to form C-C bonds since the 1970s and are often perceived as the result of two metals (i.e zinc and palladium/nickel) working in synergy. But like all relationships, there is more under the surface than what we first expected. PhD student Craig Day and Dr. Rosie Somerville from the Martin group at ICIQ have delved into the Negishi cross-coupling of aryl esters using nickel catalysis to understand how this reaction works at the molecular level and how to improve it. The results have been published in Nature Catalysis. Compared to palladium, nickel has the advantage of being readily available transition metal, ...

It's clear that rising greenhouse gas emissions are the main driver of global warming. But on a regional level, several other factors are at play. That's especially true in the Arctic - a massive oceanic region around the North Pole which is warming two to three times faster than the rest of the planet. One consequence of the melting of the Arctic ice cap is a reduction in albedo, which is the capacity of surfaces to reflect a certain amount of solar radiation. Earth's bright surfaces like glaciers, snow and clouds have a high reflectivity. As snow and ice decrease, albedo decreases and more radiation is absorbed by the Earth, leading to a rise in ...

What The Study Did: Salary information from faculty at U.S. medical schools was used to examine the association between the percentage of female clinicians in a medical specialty and the average and median salaries for that specialty.

Coral reefs are beautiful and diverse ecosystems that power the economies of many coastal communities. They're also facing threats that are driving their decline, including the planet's warming waters. This threat hit extreme levels in 2015, when high temperatures were turning corals white around the globe. Kaneohe Bay in Hawaii was hit hard; nearly half of its corals bleached. Hidden in the aftermath of this extreme event, however, were biochemical clues as to why some corals bleached while others were resistant, information that could help reefs better weather warming waters in the future. These clues have now been uncovered by researchers at Michigan State University and the University of Hawaii at Manoa. "It was kind of horrifying," said coral biologist Crawford Drury, who witnessed ...

Researchers at the University of Massachusetts Amherst have gained new insight into the biological processes of a chytrid fungus responsible for a deadly skin infection devastating frog populations worldwide. Led by cell biologist Lillian Fritz-Laylin, the team describes in a paper published Feb. 8 in Current Biology how the actin networks of Batrachochytrium dendrobatidis (Bd) also serve as an "evolutionary Rosetta Stone," revealing the loss of cytoskeletal complexity in the fungal kingdom. "Fungi and animals seem so different, but they are actually pretty closely related," says Fritz-Laylin, whose lab studies how cells move, which is a central ...

The findings are published in the prestigious journal, Nature Climate Change, and calls on businesses, the financial services industry and regulators to work more closely with climate scientists. Regulators and governments - both domestic and international - are increasingly requiring that businesses assess and disclose their vulnerability to the physical effects of climate change, for example, increased drought, bushfires and sea level rise. "People are making strategically material decisions on a daily basis, and raising debt or capital to finance these, but the decisions may not have properly considered climate risk," said lead author Dr Tanya Fiedler from the University of Sydney Business School. ...
