  • A Warming Arctic Produces Weather Extremes in Our Latitudes

    Atmospheric researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now developed a climate model that can accurately depict the frequently observed winding course of the jet stream, a major air current over the Northern Hemisphere. 

  • Study Highlights Vulnerability of Rural Coast to Sea-Level Rise

    Type “sea-level rise” in an internet search engine and almost all the resulting images will show flooded cities, with ample guidance on civic options for protecting urban infrastructure, from constructing seawalls to elevating roadways.

  • Threatened Beetles Benefit from Forest Thinning

    Wood-living beetles that use oak trees are a species-rich and threatened animal group in modern forestry and agriculture in southern Sweden.

  • Domino Effect of Species Extinctions Also Damages Biodiversity

    The mutual dependencies of many plant species and their pollinators mean that the negative effects of climate change are exacerbated.

  • A Stanford Geophysicist Discusses Geothermal Energy’s Earthquake Problem – And Possible Solutions

    On a November afternoon in 2017, a magnitude 5.5 earthquake shook Pohang, South Korea, injuring dozens and forcing more than 1,700 of the city’s residents into emergency housing.

  • NASA-Supported Monitoring Network Assesses Ozone Layer Threats

    On the heels of the first definitive signs of the ozone layer recovery last year, an international team of scientists discovered that production and emission of a banned, potent ozone-depleting chemical is on the rise again. 

  • Comet Inspires Chemistry for Making Breathable Oxygen on Mars

    Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. 

  • Finding the Cause of Capacity Loss in a Metal-Oxide Battery Material

    Because of their high energy-storage density, materials such as metal oxides, sulfides, and fluorides are promising electrode materials for lithium-ion batteries in electric vehicles and other technologies.

  • New Study Reveals an Unexpected Survival Mechanism of a Subset of Cancer Cells

    Embedded at the end of chromosomes are structures called "telomeres” that in normal cells become shorter as cells divide. 

  • What Is Known – and Not Known – About Heart Muscle Diseases in Children

    Cardiomyopathies (heart muscle diseases) in children are the focus of a new scientific statement from the American Heart Association that provides insight into the diagnosis and treatment of the diseases as well as identifying future research priorities.
