What should we do with aging marine structures?
Marine artificial structures (MAS), such as oil and gas platforms and offshore wind farms, have a finite operational period and will eventually need to be decommissioned......»»
Bioluminescence first evolved in animals at least 540 million years ago, pushing back previous oldest dated example
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study from scientists with the Smithsonian's National Museum of Natural History......»»
Gone in a puff of smoke: 52,000 square kilometers of "long unburnt" Australian habitat has vanished in 40 years
Landscapes that have escaped fire for decades or centuries tend to harbor vital structures for wildlife, such as tree hollows and large logs. But these "long unburnt" habitats can be eliminated by a single blaze......»»
From the coast to the deep sea, changing oxygen levels affect marine life in different ways
Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels change within the course.....»»
CMS Collaboration observes new all-heavy quark structures
For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose particle detector at CERN's Large Hadron Collider (LHC)......»»
Study shines light on properties and promise of hexagonal boron nitride, used in electronic and photonics technologies
Single-photon emitters (SPEs) are akin to microscopic lightbulbs that emit only one photon (a quantum of light) at a time. These tiny structures hold immense importance for the development of quantum technology, particularly in applications such as s.....»»
Laser-treated cork absorbs oil for carbon-neutral ocean cleanup
Oil spills are deadly disasters for ocean ecosystems. They can have lasting impacts on fish and marine mammals for decades and wreak havoc on coastal forests, coral reefs, and the surrounding land. Chemical dispersants are often used to break down oi.....»»
Advances in understanding the evolution of stomach loss in agastric fishes
Living beings can evolve to lose biological structures due to potential survival benefits from such losses. For example, certain groups of ray-finned fishes show such regressive evolution—medakas, minnows, puffera, and wrasses do not have a stomach.....»»
Marine microbial populations: Potential sensors of the global change in the ocean
Animal and plant populations have been extensively studied, which has helped to elucidate ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations, due to the impossibility of isolating, culturi.....»»
Meta’s new $199 Quest 2 price is a steal for the VR-curious
Move comes as support winds down for the original Quest headset. Enlarge / For just $199, you could be having as much fun as this paid model. Meta has announced it's permanently lowering the price of its aging Quest 2 h.....»»
Respiratory stress response that stunts temperate fish also affects coral reef fish
Coral reef fish, like the fish in other marine and freshwater ecosystems, are likely to reach smaller maximum sizes and start reproducing earlier with smaller and fewer eggs as climate change continues to warm up the ocean......»»
The largest marine reptile ever could match blue whales in size
Bones from the head of a reptile suggest a body that was well over 20 meters long. Enlarge (credit: Sergey Krasovskiy) Blue whales have been considered the largest creatures to ever live on Earth. With a maximum length o.....»»
First evidence of ancient human occupation found in giant lava tube cave in Saudi Arabia
If you look from above, you can see thousands of stone structures dotting the landscape of the Arabian peninsula. On the ground, you can find a bounty of stone tools and ancient fireplaces scattered along the edges of ancient lakes, as well as rock a.....»»
Ocean environment safety of nanocellulose investigated in study of mussels
Cellulose nanofibers represent a promising resource for multiple industrial sectors, but what is their impact on the marine environment? A study published in Environmental Science: Nano recently addressed this issue in a study on marine organisms con.....»»
Paleontologists unearth what may be the largest known marine reptile
The fossilized remains of a second gigantic jawbone measuring more than two meters long has been found on a beach in Somerset, UK. Experts have identified the bones as belonging to the jaws of a new species of enormous ichthyosaur, a type of prehisto.....»»
A powerful technique for tracking a protein"s fleeting shape changes
Researchers at Weill Cornell Medicine have developed a powerful, new technique to generate "movies" of changing protein structures and speeds of up to 50 frames per second......»»
Spintronics: A new path to room temperature swirling spin textures
In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magn.....»»
Marine plankton behavior could predict future marine extinctions, study finds
Marine communities migrated to Antarctica during the Earth's warmest period in 66 million years long before a mass-extinction event......»»
Improved mid-infrared nanoscopy enables 30 times clearer view of the insides of bacteria
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially.....»»
Researchers uncover human DNA repair by nuclear metamorphosis
Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging......»»
Spectator boats at large sailing events could be impacting marine wildlife with noise pollution
New research led by Heriot-Watt University in Edinburgh, Scotland, suggests that international sailing events should try to reduce the underwater noise they create to avoid impacting marine wildlife......»»
