Ancient atmospheric oxygen sleuthing with ocean chromium
Found in jewelry, car parts, pigments, and industrial chemical reactions, the metal chromium and its compounds are often employed for their color, finish, and anti-corrosive and catalytic properties. Currently, geoscientists and paleoceanographers fr.....»»
Medicinal tree successfully grown from 1,000-year-old seed found in cave
An international team of botanists, agriculturists and historians has successfully grown a mature tree from an ancient seed found in a cave in Israel. In their paper, published in the journal Communications Biology, the group describes where the seed.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
Nanostructures in the deep ocean floor hint at life"s origin
Researchers led by Ryuhei Nakamura at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan and The Earth-Life Science Institute (ELSI) of Tokyo Institute of Technology have discovered inorganic nanostructures surrounding deep-ocean hydro.....»»
"Invisible forest" of phytoplankton thrives as ocean warms, study shows
An "invisible forest" of phytoplankton is thriving in part of our warming ocean, new research shows......»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
Atmospheric methane increase during pandemic due primarily to wetland flooding, satellite data analysis finds
A new analysis of satellite data finds that the record surge in atmospheric methane emissions from 2020 to 2022 was driven by increased inundation and water storage in wetlands, combined with a slight decrease in atmospheric hydroxide (OH). The resul.....»»
Tropical and subtropical industrial fisheries account for about 70% of methylmercury fished from the ocean: Study
Industrial fishing practices are increasing human exposure to methylmercury, a neurotoxicant associated with developmental delays in children and impaired cardiovascular health in adults......»»
1,000-year-old textiles reveal cultural resilience in the ancient Andes
Archaeologists have analyzed textiles from the ancient city of Huacas de Moche, Peru, showing how the population's cultural traditions survived in the face of external influence......»»
New Zealand scientists discover ghostly "spookfish"
Scientists in New Zealand said Tuesday they have discovered a new species of "ghost shark", a type of fish that prowls the Pacific Ocean floor hunting prey more than a mile down......»»
Businesses trying to come clean about their impact on nature can end up concealing more than they reveal
Humans have overfished the ocean, cleared forests, polluted water and created a climate crisis by burning fossil fuels. These actions are affecting biodiversity around the world, from remote islands to our own backyards......»»
Water-free manufacturing approach could help advance 2D electronics integration
The future of technology has an age-old problem: rust. When iron-containing metal reacts with oxygen and moisture, the resulting corrosion greatly impedes the longevity and use of parts in the automotive industry......»»
Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»
Data from robots show steady increase in deep-ocean warming
New research published Sept. 19 in Geophysical Research Letters shows that using data collected by deep ocean robots, called Deep Argo floats, combined with historical data from research vessels has increased confidence that parts of the global deep.....»»
Scientists propose new "golden rules" for sustainable fishing
Top ocean experts have published a report that redefines the concept of "sustainable fishing" and proposes 11 "golden rules" that radically challenge the flawed approach that currently prevails in fisheries management......»»
Can AI help save our planet?
Last year was the hottest on record. Around the world, we are witnessing more extreme events—from massive forest fires to floods to "hot tub'" ocean temperatures—with devastating consequences for human life and our planet's biodiversity......»»
Study reveals large ocean heat storage efficiency during the last deglaciation
As one of the largest heat reservoirs in the climate system, the global ocean absorbs more than 90% of the excess energy from ongoing anthropogenic warming. In the last century, the greatest warming in the ocean has occurred in the upper 500 m, with.....»»
Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Sea surface micro layer: Researchers study boundary between the ocean and the air
The boundary between the ocean and the atmosphere, where the air and sea interact, is known as the sea surface microlayer. Understanding how nutrients, pollutants and organic matter are exchanged between the air and the sea is also vital for better u.....»»
Mysterious Pacific Ocean sounds identified as a type of whale—a new AI app helps track them
A team of oceanographers and marine biologists from the NOAA Pacific Islands Fisheries Science Center and Oregon State University has identified a mysterious noise heard in the Pacific Ocean for two decades as the sounds of Bryde's whales......»»
Cleaning the ocean has a price — and layers of complications
Pulling plastic from the ocean and recycling that into auto parts is the plan. The challenges are immense, but worth it......»»
