Published Bitcoin mining has 'very worrying' impacts on land and water, not only carbon



As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.
Published Adding crushed rock to farmland pulls carbon out of the air



Adding crushed volcanic rock to farmland can pull carbon dioxide out of the air. In a field test, scientists found that the process works even in dry climates.
Published Light, freshwater sticks to Greenland's east coast



Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Certain per- and polyfluoroalkyl 'forever chemicals' identified as potential risk factor for thyroid cancer



Researchers have discovered a link between certain per- and polyfluoroalkyl substances (PFAS) and an increased risk for thyroid cancer.
Published Superdeep diamonds provide a window on supercontinent growth



Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process.
Published Researchers probe molten rock to crack Earth's deepest secrets



An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.
Published Researchers create the most water-repellent surface ever



A revised method to create hydrophobic surfaces has implications for any technology where water meets a solid surface, from optics and microfluidics to cooking.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes



As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published Plants transformed into detectors of dangerous chemicals



What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published Land use: Producing more food and storing more carbon



Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
Published New extremes in stratospheric water vapor



The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published DNA shows where Washington culvert replacements helped spawning salmon



University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.
Published Scientists discover deepest known evidence of coral reef bleaching



Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published New study finds 50-year trend in hurricane escalation linked to climate change



New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
Published California supervolcano is cooling off but may still cause quakes



New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
Published Drought conditions expose rivers to hotter water temperatures



A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published Ancient diamonds shine light on the evolution of Earth



Formed millions to billions of years ago, diamonds can shine light into the darkest and oldest parts of the Earth's mantle. The analysis of ancient, superdeep diamonds dug up from mines in Brazil and Western Africa, has exposed new processes of how continents evolved and moved during the early evolution of complex life on Earth. These diamonds that were formed between 650 and 450 million years ago on the base of the supercontinent Gondwana, were analysed by an international team of experts, and have shown how supercontinents such as Gondwana were formed, stabilised, and how they move around the planet.
Published Researchers study one of the world's darkest rivers



They set out to study the Congo Basin's carbon cycle and in the process have become aware of one of the world's darkest blackwater rivers: the Ruki. In the first study on this major jungle river, an international research team explains how this blackness comes about and what it says about the river system's carbon balance.
Published How to build greener data centers? Scientists say crank up the heat



Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.
Published How to help save plants from extinction



Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.
