The Gulf Stream transport of water through the Florida Strait has slowed by 4% over the past four decades, with a 99% certainty that this weakening is more than expected from random chance, according to a new study.

With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.

Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.

Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.

Researchers have identified the threat greenwashing poses to a 'nature positive' world, one where environmental decline halts and biodiversity outcomes improve.

The western edge of Chicago -- including the North and South Lawndale, East Garfield Park, Archer Heights and Brighton Park neighborhoods -- experiences up to 32% higher concentrations of nitrogen dioxide (NO2) air pollution compared to the rest of the city.

Multiyear La Niña events have become more common over the last 100 years, according to a new study. Five out of six La Nina events since 1998 have lasted more than one year, including an unprecedented triple-year event.

In the 'weather kitchen,' the interplay between the Azores High and Icelandic Low has a substantial effect on how much warm water the Atlantic transports to the Arctic along the Norwegian coast. But this rhythm can be thrown off for years at a time. Experts finally have an explanation for why: Due to unusual atmospheric pressure conditions over the North Atlantic, low-pressure areas are diverted from their usual track, which disrupts the coupling between the Azores High, the Icelandic Low and the winds off the Norwegian coast. This finding is an important step toward refining climate models and more accurately predicting the fate of Arctic sea ice in the face of progressing climate change.

A new study suggests patches of fertile soil in the Amazon, known as dark earth, were intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.

An international research team has used the James Webb Space Telescope and the Atacama Large Millimeter/submillimeter Array to observe the most distant galaxy protocluster to date, 13.14 billion light-years away. The team has successfully captured the 'core region' of the galaxy protocluster, which corresponds to a metropolitan area with a particularly high number density of galaxies. The team has revealed that many galaxies are concentrated in a small area and that the growth of galaxies is accelerated. Furthermore, the team used simulations to predict the future of the metropolitan area and found that the region will merge into one larger galaxy within tens of millions of years. These results are expected to provide important clues regarding the birth and growth of galaxies.

Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.

Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.

An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.

In the summer of 2022, one of Tyrol's largest glaciers experienced its most significant loss of mass on record. Last year, the Hintereisferner in Tyrol, Austria, reached its Glacier Loss Day (GLD) earlier than ever before. The GLD serves as an indicator of a glacier's health throughout the year, similar to how the Earth Overshoot Day measures Earth's resource consumption.

Researchers studying diamond-rich rocks from Western Australia's Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth's surface where they can be mined, which could greatly help in the global hunt for new deposits.

Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.

Exposure to endocrine-disrupting chemicals like PFAS and phenols are implicated in hormone-mediated cancers of the breast, ovaries, skin and uterus. To learn more about the environmental exposures experienced by women who developed these cancers, researchers analyzed data from NHANES and found that women who reported having cancer had significantly higher levels of these chemicals in their bodies.

Scientists have used data from the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early Release Science (CEERS) Survey to change the way we think about the universe and its distant galaxies. Astronomers authored a paper confirming very bright galaxies in the early universe, while also disproving the identification of what would have been the most distant galaxy ever found.
