How weather patterns will change in the future      (via sciencedaily.com)     Original source 

In a warming Pacific Northwest, summers are getting hotter and winters less cold, but the atmospheric patterns that influence the weather aren't necessarily expected to become stronger or more frequent by the end of the century, according to a new study.

New study definitively confirms Gulf Stream weakening, understanding the changes could help predict future trends in extreme events      (via sciencedaily.com)     Original source 

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.

Jellyfish, with no central brain, shown to learn from past experience      (via sciencedaily.com)     Original source 

Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.

Migratory birds can be taught to adjust to climate change      (via sciencedaily.com)     Original source 

One result of climate change is that spring is arriving earlier. However, migratory birds are not keeping up with these developments and arrive too late for the peak in food availability when it is time for breeding. By getting the birds to fly a little further north, researchers have observed that these birds can give their chicks a better start in life.

Researchers' analysis of perching birds points to new answers in evolutionary diversification      (via sciencedaily.com)     Original source 

When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time.

We could sequester CO2 by 're-greening' arid lands, plant scientists say      (via sciencedaily.com)     Original source 

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.

Greenwashing a threat to a 'nature positive' world      (via sciencedaily.com)     Original source 

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

Chicago's West Side is air pollution hotspot      (via sciencedaily.com)     Original source 

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.

Understanding the sex life of coral gives hope of clawing it back from the path to extinction      (via sciencedaily.com)     Original source 

Scientists have mapped the reproductive strategies and life cycle of an endangered coral species, the purple cauliflower soft coral Dendronephthya australis. Lab-grown larvae have been successfully introduced back into the wild.

Long-lasting La Nina events more common over past century      (via sciencedaily.com)     Original source 

Multiyear La NiƱa 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.

Riddle of varying warm water inflow in the Arctic now solved      (via sciencedaily.com)     Original source 

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.

Ancient Amazonians intentionally created fertile 'dark earth'      (via sciencedaily.com)     Original source 

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.

Genetically modifying individual cells in animals      (via sciencedaily.com)     Original source 

Researchers have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered genes that are relevant for a severe rare genetic disorder.

Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle      (via sciencedaily.com)     Original source 

A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly, these early crocodylomorphs were not the lethargic, semi-aquatic creatures we are familiar with today; they were small, active, and fully terrestrial. The study also suggests that this slow-growth strategy was not a mere evolutionary quirk but a survival mechanism, as only the slow-growing crocodylomorphs managed to survive the End-Triassic mass extinction. This stands in stark contrast to the fast-growing dinosaurs of the same era, setting the stage for the divergent evolutionary paths that would later define their modern descendants.

Urban light pollution linked to smaller eyes in birds      (via sciencedaily.com)     Original source 

The bright lights of big cities could be causing an evolutionary adaptation for smaller eyes in some birds, a new study indicates. Researchers found that two common songbirds, the Northern Cardinal and Carolina Wren, that live year-round in the urban core of San Antonio, Texas, had eyes about 5% smaller than members of the same species from the less bright outskirts. Researchers found no eye-size difference for two species of migratory birds, the Painted Bunting and White-eyed Vireo, no matter which part of the city they lived in for most of the year. The findings have implications for conservation efforts amid the rapid decline of bird populations across the U.S.

New research brings greater understanding of Asian winter monsoon      (via sciencedaily.com)     Original source 

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.
