This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO2. The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. The confluence of tectonically exhumed...
Archaeologists discover oldest known bead in the Americas
The bead found at the La Prele Mammoth site in Wyoming's Converse County is about 12,940 years old and made of bone from a hare.
Oregon State University Research Makes Key Advance for Capturing Carbon From the Air
A chemical element so visually striking it was named for a goddess shows a “Goldilocks” level of reactivity – neither too much nor too little – that makes it a strong candidate as a carbon scrubbing tool.
Increased Rainfall Threatens UK Sea Urchins
Sea urchins exposed to diluted seawater for long periods show signs of physical deterioration, according to scientists from British Antarctic Survey, the University of Cambridge and the Scottish Association for Marine Science.
Temperatures are Rising, But Soil is Getting Wetter — Why?
Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide and, perhaps most importantly, how productive our food systems are.
Immune genes are altered in Alzheimer’s patients’ blood
A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for...
Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets
Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon...
Conversion process turns greenhouse gas into ethylene
Engineers have created a more efficient way of converting carbon dioxide into valuable products while simultaneously addressing climate change.
Sensors made from ‘frozen smoke’ can detect toxic formaldehyde in homes and offices
Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
Physical Activity Is Insufficient to Counter Cardiovascular Risk Associated With Sugar-Sweetened Beverage Consumption
Contrary to popular belief, the benefits of physical activity do not outweigh the risks of cardiovascular disease associated with drinking sugar-sweetened beverages, according to a new study led by Harvard T. H. Chan School of Public Health.
