In Egypt"s Red Sea, corals fade as oceans warm
Standing on a boat bobbing gently in the Red Sea, Egyptian diving instructor Mohamed Abdelaziz looks on as tourists snorkel amid the brilliantly coloured corals, a natural wonder now under threat from climate change......»»
Holes in baby dinosaur bones show how football-sized hatchlings grew to 3-ton teens
Despite their public image as torpid, lumbering creatures, many dinosaurs were evidently warm-blooded, highly active animals, capable of prolonged and strenuous aerobic exercise......»»
As heat waves warm the Pacific Ocean, effects on marine life remain murky
Scientists are pretty good at recognizing marine heat waves. A global network of thousands of oceanic buoys and orbiting satellites allow them to see, in real time, ocean surface temperatures, changing currents and storm systems as they develop, move.....»»
Jellyfish: Our complex relationship with the oceans" anti-heroes
Ding! The courier hands me an unassuming brown box with "live animals" plastered on the side. I begin carefully unboxing. The cardboard exterior gives way to a white polystyrene clamshell, cloistering a pearly sphere-shaped, water-filled bag. Lightly.....»»
Did animal evolution begin with a predatory lifestyle?
Were the first animals predators or filter feeders like the sponges living in today's oceans? And what role did symbiosis with algae play, as with reef-building corals? Surprising findings by a research group led by Prof. Dr. Thomas W. Holstein of He.....»»
Genetic research is identifying disease-resistant super corals in the Caribbean
Witnessing disease outbreaks that have nearly annihilated staghorn coral colonies in the Caribbean, Northeastern scientist Steven Vollmer wondered what lessons a few lone survivors might offer for the future of coral reefs. Would it be possible to id.....»»
Superbolts: Scientists figure out what causes Earth"s strongest lightning
Superbolts are more likely to strike the closer a storm cloud's electrical charging zone is to the land or ocean's surface, a new study finds. These conditions are responsible for superbolt "hotspots" above some oceans and tall mountains......»»
Keck Cosmic Web Imager offers best glimpse yet of the filamentous network that connects galaxies
Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While astronomers have known about the cosmic web for decades, and.....»»
Accounting for oxygen in modeling coastal ecosystems
Driven by climate change and pollution, the decline of oxygen levels in oceans is altering biogeochemical cycles, threatening marine plants, animals and ecosystems. But how accurately are we projecting the fate of marine life? If models of marine eco.....»»
Tropical climates are the most biodiverse on Earth, but it"s not only because of how warm and wet they are
Life exists in every conceivable environment on Earth, from the peaks of towering mountains to the remote stretches of isolated islands, from sunlit surfaces to the darkest depths of the oceans. Yet, this intricate tapestry of existence isn't spread.....»»
Study sheds new light on strange lava worlds
Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system......»»
Exploring the effect of water on seismic wave attenuation in the upper mantle
The oceanic lithosphere, which constitutes the top layer including Earth's crust and mantle below the oceans, has long intrigued scientists due to its peculiar behavior. This layer appears to glide over a weaker region below called the asthenosphere,.....»»
AI predicts sea surface temperature cooling during tropical cyclones
Tropical cyclones are extreme weather events, characterized by a circular form and formation over warm tropical oceans experiencing low atmospheric pressure, high winds and heavy rain. Tropical storms exceed 39 miles per hour (mph), while hurricanes.....»»
Data show container deposit schemes reduce rubbish on our beaches
Our beaches are in trouble. Limited recycling programs and a society that throws away so much have resulted in more than 3 million metric tons of plastic polluting the oceans. An estimated 1.5–1.9% of this rubbish ends up on beaches......»»
Red Sea corals threatened by mystery sea urchin deaths
The Red Sea's spectacular coral reefs face a new threat, marine biologists warn—the mass death of sea urchins that may be caused by a mystery disease......»»
Behold the Latest Treasures Unearthed at Mexico City"s Templo Mayor
A stone chest with 15 anthropomorphic sculptures and numerous beads, shells, and corals have been discovered in the heart of the ancient Aztec capital......»»
Environmental physicist discusses marine heat waves
An extraordinary heat wave is assailing the world's oceans with an intensity that is surprising climate researchers. Environmental physicist Nicolas Gruber provides some context......»»
Riddle of varying warm water inflow in the Arctic now solved
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......»»
Revealing the role of anthropogenic water regulation in shaping riverine dissolved organic carbon fluxes
Riverine dissolved organic carbon (DOC) plays a crucial role in supporting microbial ecosystems in rivers and oceans while also contributing to greenhouse gas emissions from freshwater systems......»»
Chameleon-inspired coating could cool and warm buildings through the seasons
As summer turns to fall, many people will be turning off the air conditioning and firing up heaters instead. But traditional heating and cooling systems are energy-intensive, and because they typically run on fossil fuels, they aren't sustainable. No.....»»
Black holes eat faster than previously expected: New finding might explain why quasars flare and fade so quickly
A new Northwestern University-led study is changing the way astrophysicists understand the eating habits of supermassive black holes......»»
