When heat flows backwards: A neat solution for hydrodynamic heat transport

When we think about heat travelling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing kinetic energy in the process. But in some materials heat can travel in a different way, flowing like water in a pipeline that – at least in principle – can be forced to move in a direction of choice. This second regime is called hydrodynamic heat transport. Heat conduction is mediated by movement of phonons, which are collective excitations of atoms in solids, ...

UW researchers use satellite data to quantify methane loss in the stratosphere

Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30% of modern global warming to methane. Observations show that methane levels have increased over time, but the factors driving changes in the rate of accumulation remain unclear. Methane stays in the atmosphere for approximately 10 years before it is broken down, or removed. Researchers need to know how much methane is removed to gauge what percentage of emissions are accumulating in the atmosphere, but the methane removal process is difficult ...

Climate change could halve areas suitable for cattle, sheep and goat farming by 2100

A new study conducted at the Potsdam Institute for Climate Impact Research (PIK) shows that grassland-based grazing systems – currently covering a third of the Earth’s surface and representing the world’s largest production system – will see a severe contraction as global temperatures rise. Depending on the scenario analysed, 36-50 percent of the land with suitable climatic conditions for grazing today will experience a loss of viability by 2100, affecting more than 100 million pastoralists and up to 1.6 billion grazing animals. The study, published in the scientific journal PNAS today, identifies a ‘safe climatic space’ for cattle, sheep and goat grazing. ...

Building blocks of life discovered in Bennu asteroid rewrite origin story

UNIVERSITY PARK, Pa. — Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA’s OSIRIS-REx mission. How those amino acids — the molecules that create proteins and peptides in DNA — formed in space was a mystery, but new research led by Penn State scientists shows they could have originated in an icy-cold, radioactive environment at the dawn of Earth’s solar system. According to the researchers, who published new findings today ...

Deep-sea microbes get unexpected energy boost

For many years, the deep ocean has been seen as a nutrient-poor environment where microbes living in the water survive on very limited resources. But new research from the University of Southern Denmark (SDU) challenges that idea. A study led by SDU-biologists at the Department of Biology shows that nutrients might not be so sparse after all in the deep and that microbes have access to a hitherto unknown source of dissolved organic food. The study shows that sinking organic particles—known as marine snow—begin to leak dissolved carbon and nitrogen when they reach depths of 2–6 kilometres, presenting microbes in the surrounding seawater with nutrients. The leakage is caused ...
