UNIVERSITY PARK, Pa. — As climate change worsens global drought conditions, hindering crop production, the search for ways to capture and store atmospheric carbon causing the phenomenon has intensified. Penn State researchers have developed a new high-tech tool that could spur changes in how crops withstand drought, acquire nitrogen and store carbon deeper in soil. In findings published in the January issue of Crop Science, they describe a process in which the depth of plant roots can be accurately estimated by scanning leaves with ...

Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N2) and hydrogen gas (H2) in a reactor in the presence of a catalyst. This process requires high levels of temperature and pressure, resulting in substantial power consumption. Indeed, ammonia production is estimated to consume 1%-2% of the world’s electricity and to account for about 3% of global carbon emissions. In pursuit of more sustainable alternatives, researchers affiliated with the Center for Development of Functional Materials (CDMF) ...

UNIVERSITY PARK, Pa. — Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team led by Penn State researchers has now found that these ecosystems appear to keep the energy exchanges in balance — a finding that the scientists called surprising. Scientists ...

CORVALLIS, Ore. – A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.

For most people, reading about the difference between a global average temperature rise of 1.5 C versus 2 C doesn’t conjure up a clear image of how their daily lives will actually be affected. So, researchers at MIT have come up with a different way of measuring and describing what global climate change patterns, in specific regions around the world, will mean for people’s daily activities and their quality of life. The new measure, called “outdoor days,” describes the number of days per year that outdoor temperatures are neither too ...

A collaboration between scientists from St. Jude Children’s Research Hospital and Dana-Farber Cancer Institute uncovered four proteins that govern the identity of anaplastic large cell lymphoma (ALCL), an aggressive form of cancer. These proteins comprise a core regulatory circuit (CRC) that surprisingly incorporates a dysregulated signaling protein. Establishing the CRC for this lymphoma gives researchers insight into potential vulnerabilities that may be future therapeutic targets. The findings were published today in Cell Reports Medicine. “Mutations in signaling pathways have long been known to drive oncogenic transformation ...

Expanding organic cropland can lead to increased pesticide use in surrounding conventional fields while reducing pesticide use on nearby organic fields, according to a study based in a leading U.S. crop-producing region. The findings provide insight into overlooked environmental impacts of organic agriculture and suggest that clustering organic fields could reduce pesticide use at the landscape scale. Organic agricultural practices are designed to have less negative local environmental impacts than other forms of intensive agriculture. However, the ...
