A new study published in the journal Environmental Science & Technology and led by researchers at Columbia University Mailman School of Public Health identifies the hidden geological mechanisms behind widespread uranium contamination in Eastern Karnataka, India, where 78% of tested groundwater exceeds safe drinking limits for uranium, and some groundwater uranium contamination reaches levels 75 times the U.S. EPA limit. Uranium exposure can affect the kidneys, bones, and the liver, yet contamination often goes undetected. https://phys.org/news/2025-06-uncover-uranium-groundwater-contamination.html Environment Thu, 26 Jun 2025 16:40:16 EDT news670174802 Magnetic fields can be used to stimulate blood vessel growth, according to a study published in the journal Science and Technology of Advanced Materials. The findings, by researchers at the Tecnico Lisboa and NOVA School of Science and Technology in Portugal, could lead to new treatments for cancers and help regenerate tissues that have lost their blood supply. https://phys.org/news/2021-07-blood-vessel-formation-magnetic-fields.html Biotechnology Thu, 22 Jul 2021 07:46:13 EDT news546158770 The middle of the Earth's oceans are filled with vast systems of rotating currents known as subtropical gyres. These regions occupy 40% of the Earth's surface and have long been considered remarkably stable biological deserts, with little variation in chemical makeup or the nutrients needed to sustain life. https://phys.org/news/2019-08-uncover-ocean-iron-mystery.html Earth Sciences Fri, 30 Aug 2019 03:39:53 EDT news486355182 A nearly $5 billion expected settlement for last year's toxic flood that killed 17 people in Brazil could be challenged by prosecutors, who say the amount is not enough. https://phys.org/news/2016-02-brazil-prosecutor-threatens-torpedo-bn.html Environment Fri, 19 Feb 2016 18:11:07 EST news375127861 The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed – with implications for future climate prediction. https://phys.org/news/2013-07-scientists-variability-iron-oceans-climate.html Earth Sciences Fri, 19 Jul 2013 06:11:27 EDT news293433054 A report on productive aquifers in hard rock on the west coast of Peninsular Malaysia suggests greater water supply than has previously been recognised. The work, published in the Pertanika Journal of Science and Technology, suggests which factors should be taken into account before drilling for industrial and residential water supplies, as groundwater becomes a more important resource worldwide. https://phys.org/news/2012-09-groundwater-viable-resource-malaysians.html Environment Wed, 05 Sep 2012 08:40:00 EDT news266053111 Sony today announced the development of an energy storage module using lithium-ion rechargeable batteries made with olivine-type lithium iron phosphate as the cathode material. Key features of olivine-type lithium iron phosphate cell include high power output, long-life performance and excellent thermal stability. Sample shipments of the new module are scheduled to begin from June, 2010. https://phys.org/news/2010-06-sony-12kwh-class-energy-storage-module.html Engineering Wed, 23 Jun 2010 15:30:01 EDT news196525203 Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. Their findings have potentially important implications for understanding global climate, both past and future. https://phys.org/news/2009-11-iron-patterns-nitrogen-fixation-atlantic.html Earth Sciences Mon, 02 Nov 2009 12:28:36 EST news176387275
