  • Living coral cover will slow future reef dissolution

    Living coral cover will slow future reef dissolution

    A team led by David Kline, a staff scientist at the Smithsonian Tropical Research Institute, asked what would happen if they lowered the pH on a living coral reef. By using computer-controlled pulses of carbon dioxide (CO2) enriched seawater, they ...

  • Climate change water variability hurts salamander populations

    Climate change water variability hurts salamander populations

    New research from the University of Montana suggests that streamflow variability brought on by climate change will negatively affect the survival of salamanders. UM biology Professor Winsor Lowe and his partners studied spring salamanders living ...

  • Not all meat is created equal: How diet changes can sustain world`s food production

    Not all meat is created equal: How diet changes can sustain world`s food production

    If you wanted to really mess with the world`s food production, a good place to start would be in Morocco. They don`t grow much here, but it is home to mines containing most of the world`s known reserves of phosphate rock, the main source of the ...

  • Source water key to bacterial water safety in remote Northern Australia

    Source water key to bacterial water safety in remote Northern Australia

    In the wet-dry topics of Australia, drinking water in remote communities is often sourced from groundwater bores. The geochemistry of that groundwater impacts the occurrence of opportunistic pathogens in the drinking water supply, researchers now ...

  • Urban stormwater could release contaminants to ground, surface waters

    Urban stormwater could release contaminants to ground, surface waters

    A good rainstorm can make a city feel clean and revitalized. However, the substances that wash off of buildings, streets and sidewalks and down storm drains might not be so refreshing. Now, researchers reporting in ACS` Environmental Science ...

  • Monitoring CO2 leakage sites on the ocean floor

    Monitoring CO2 leakage sites on the ocean floor

    Injecting carbon dioxide (CO2) deep below the seabed could be an important strategy for mitigating climate change, according to some experts. However, scientists need a reliable way to monitor such sites for leakage of the greenhouse gas. Now, ...

  • New evidence highlights growing urban water crisis

    New evidence highlights growing urban water crisis

    New research has found that in 15 major cities in the global south, almost half of all households lack access to piped utility water, affecting more than 50 million people. Access is lowest in the cities of sub-Saharan Africa, where only 22% of ...

  • A battery-free sensor for underwater exploration

    A battery-free sensor for underwater exploration

    To investigate the vastly unexplored oceans covering most our planet, researchers aim to build a submerged network of interconnected sensors that send data to the surface -- an underwater "internet of things." But how to supply constant power to ...

  • Origin of massive methane reservoir identified

    Origin of massive methane reservoir identified

    New research from Woods Hole Oceanographic Institution (WHOI) published Aug. 19, 2019, in the Proceedings of the National Academy of Scienceprovides evidence of the formation and abundance of abiotic methane -- methane formed by chemical ...

  • Paper filter from local algae could save millions of lives in Bangladesh

    Paper filter from local algae could save millions of lives in Bangladesh

    The problem of access to safe drinking water in most parts of Bangladesh is a persistent challenge. Now, a team of scientists from Uppsala University, Sweden, and Dhaka University, Bangladesh, shows that a locally growing and previously unexploited ...

  • Circulation of water in deep Earth`s interior

    Circulation of water in deep Earth`s interior

    The existence of water in deep Earth is considered to play an important role in geodynamics, because water drastically changes the physical properties of mantle rock, such as melting temperature, electric conductivity, and rheological properties. ...

  • Ice sheets impact core elements of the Earth`s carbon cycle

    Ice sheets impact core elements of the Earth`s carbon cycle

    The Earth`s carbon cycle is crucial in controlling the greenhouse gas content of our atmosphere, and ultimately our climate. Ice sheets which cover about 10 percent of our Earth`s land surface at present, were thought 20 years ago to be frozen ...

  • Oil and water: better monitoring needed to secure vital groundwater supplies, researchers say

    Oil and water: better monitoring needed to secure vital groundwater supplies, researchers say

    When it comes to groundwater quality, fracking receives much of the public attention but misses most of the picture, according to hydrogeologists Jennifer McIntosh from the University of Arizona and Grant Ferguson from the University of Saskatchewan ...

  • Climate change `disrupts` local plant diversity, study reveals

    Climate change `disrupts` local plant diversity, study reveals

    Faster rates of climate change could be increasing the diversity of plant species in many places, according to research from the University of York. Researchers have discovered that the numbers of plant species recorded by botanists have ...

  • Fishing leads to investigation of environmental changes in waterways

    Fishing leads to investigation of environmental changes in waterways

    A fisherman`s curiosity led to identification of the correlation between microbial communities in recreational freshwater locales and seasonal environmental changes, according to a team of researchers from Penn State. Zachary Weagly, a 2018 ...

  • Solving mystery of pilot Amelia Earhart

    Solving mystery of pilot Amelia Earhart

    Researchers from the University of New Hampshire`s Marine School are part of the crew, led by National Geographic Explorer-at-Large Robert Ballard, that is setting out to hopefully find answers to questions around the disappearance of famed pilot ...

  • Unique dietary strategy of a tropical marine sponge

    Unique dietary strategy of a tropical marine sponge

    Research conducted at the University of Hawaiʻi (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) on a marine sponge in Kāneʻohe Bay, O?ahu revealed a unique feeding strategy, wherein the sponge animal ...

  • Sunscreens release metals and nutrients into seawater

    Sunscreens release metals and nutrients into seawater

    Beachgoers are becoming increasingly aware of the potentially harmful effects UV filters from sunscreens can have on coral and other marine organisms when the protective lotions wash off their bodies into the ocean. Now, researchers have studied how ...
