  • Green tea consumption and cerebral white matter lesions in community-dwelling older adults without dementia

    Green tea consumption and cerebral white matter lesions in community-dwelling older adults without dementia

    Abstract This study investigated the association between green tea or coffee consumption with cerebral white matter lesions and hippocampal and total brain volumes among 8766 community-dwelling participants recruited from the Japan Prospective Studies Collaboration for Aging and Dementia between 2016 and 2018. A Food Frequency Questionnaire was used to assess green tea and coffee consumption,…

    Earth shattered heat records in 2023 and 2024: is global warming speeding up?

    Earth’s temperature has been climbing for decades.Credit: Mark J. Terrill/AP/Alamy Earth’s temperature has surged in the past two years, and climate scientists will soon announce that it hit a milestone in 2024: rising to more than 1.5 °C above pre-industrial levels. But is this sudden spike just a blip in the climate data, or an…

    Writers & Writing: Memoir blends science and nature

    “23 Woodcock in 22 Years,” by Jeff Wilkerson (University of Iowa Press, ISBN 978-1-60938-987-1) At first glance, Jeff Wilkerson’s memoir of science and nature, “23 Woodcock in 22 Years,” seems a bit of an anomaly. The subtitle, “Reflections on Hunting, the Night Sky and Our Place in the Universe,” seems even more incongruous. #placement_661376_0_i{width:100%;margin:0 auto;}…

    ‘Precocious’ early-career scientists with high citation counts proliferate

    In 2023, more than 450 scientists who had begun publishing research only in the previous eight years were among the ranks of most-cited researchers. Credit: Getty The number of ‘precocious’ scientists — those who become top-cited authors early in their careers — has surged in the past few years, according to an analysis1 of the…

  • Advancing the science of headwater streamflow for global water protection

    Advancing the science of headwater streamflow for global water protection

    Abstract The protection of headwater streams faces increasing challenges, exemplified by limited global recognition of headwater contributions to watershed resiliency and a recent US Supreme Court decision limiting federal safeguards. Despite accounting for ~77% of global river networks, the lack of adequate headwaters protections is caused, in part, by limited information on their extent and…
