A breakthrough study has uncovered that the Southern Ocean's power to pull carbon dioxide from the atmosphere fluctuates dramatically depending on winter sea ice. When sea ice lingers longer into winter, the ocean absorbs up to 20% more CO2, thanks ...
In a surprising twist during an air quality study in Oklahoma, researchers detected MCCPs an industrial pollutant never before measured in the Western Hemisphere's atmosphere. The team suspects these toxic compounds are entering the air through ...
Underground fungi may be one of Earth s most powerful and overlooked allies in the fight against climate change, yet most of them remain unknown to science. Known only by DNA, these "dark taxa" make up a shocking 83% of ectomycorrhizal species fungi ...
Atmospheric rivers, while vital for replenishing water on the U.S. West Coast, are also the leading cause of floods though storm size alone doesn t dictate their danger. A groundbreaking study analyzing over 43,000 storms across four decades found ...
A pioneering study reveals how archaeologists' satellite tools can be repurposed to tackle climate change. By using AI and satellite LiDAR imagery from NASA and ESA, researchers have found a faster, ...
Where do microplastics really go after entering the environment? MIT researchers discovered that sticky biofilms naturally produced by bacteria play a surprising role in preventing microplastics from accumulating in riverbeds. Instead of trapping ...
Ancient carbon thought to be safely stored underground for millennia is unexpectedly resurfacing literally. A sweeping international study has found that over half of the carbon gases released by rivers come from long-term, old carbon sources like ...
Mercury contamination is surfacing as a serious concern in parts of Georgia and South Carolina, particularly in regions like the Okefenokee Swamp. University of Georgia researchers found alarmingly high levels of the neurotoxic metal in alligators, ...
What if all life on Earth followed a surprisingly simple pattern? New research shows that in every region, species tend to cluster in small hotspots and then gradually thin out. This universal rule applies across drastically different organisms and ...
Beneath Earth s surface, nearly 3,000 kilometers down, lies a mysterious layer where seismic waves speed up inexplicably. For decades, scientists puzzled over this D' layer. Now, groundbreaking ...
Scientists have built a lab model that visually tracks how microscopic contact points between fault surfaces evolve during earthquake cycles, revealing the hidden mechanics behind both the slow ...
A new study details processes that keep pollutants aloft despite a drop in ...

The fossils of ancient salamander-like creatures in Scotland are among the most well-preserved examples of early stem tetrapods -- some of the first animals to make the transition from water to land. ...

A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope ...

Researchers created a detailed physical model that suggests a major Atlantic Ocean current will weaken far less under climate change than indicated by more extreme climate model ...

Replanting forests can help cool the planet even more than some scientists once believed, especially in the tropics. But even if every tree lost since the mid-19th century is replanted, the total ...

Lead contamination in municipal water sources is a consistent threat to public health. Ingesting even tiny amounts of lead can harm the human brain and nervous system -- especially in young children. ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Scientists have now used Japan's extensive network ...

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of ...

Scientists show that wolves that are eating sea otters in Alaska have much higher concentrations of mercury than those eating other prey such as deer and ...

With wildfires increasing in frequency, severity, and size in the Western U.S., researchers are determined to better understand how smoke impacts air quality, public health, and even the weather. As ...

Researchers find that iron powder, an inexpensive alternative to activated carbon, does a better job at filtering PFOS from water -- it's 26 times more ...

Researchers found that digestion in hawks and owls can alter the results of isotopic analysis in pellets and ...

Most people have witnessed -- or rather smelled -- when a protein enzyme called sulfite reductase works its magic. This enzyme catalyzes the chemical reduction of sulfite to hydrogen sulfide. ...

Researchers conducted a systematic review of 99 scientific publications that compared the flora or fauna of old-growth forests, managed forests and clearcut sites in boreal Europe. The reviewed ...

Alterations to the diet of pests could impact how quickly they can adapt to ...

Plankton may be tiny, but they play an important role in the ocean. As the foundation of marine ecosystems, they support ocean food webs and help regulate Earth's climate by storing carbon. ...

New international research demonstrates global-scale patterns in how El Ni o-Southern Oscillation (ENSO) influences mangrove growth and degradation. Previously, impacts had only been documented at ...

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA ...

New research shows how rapidly proliferating turf algae are waging 'chemical warfare' to inhibit the recovery of kelp forests along Maine's warming ...

Researchers have analyzed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it ...

Engineers developed a membrane that filters the components of crude oil by their molecular size, an advance that could dramatically reduce the amount of energy needed for crude oil ...
