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......»»
Study: Airway hillocks challenge our understanding of lung biology
Airway hillocks are mysterious, flat-topped structures that were only recently identified within regular lung tissue, and their role in airway biology and pathology has previously been unknown......»»
Behavioral therapy against aging: Researchers study the effect of therapies on older dogs
It is well known that getting plenty of exercise and mental training are important for a long and healthy life. But which is more effective? Do the tasks develop abilities that go beyond them?.....»»
Climate change reveals intricate dynamics of reproductive barriers in marine species
Monash University scientists have uncovered insights into how rising temperatures influence the reproductive interactions and species boundaries of marine organisms......»»
Microgravity-grown crystals reveal new insights into protein structures
Biochemists have long been working around a blind spot when it comes to proteins. They know that hydrogen constitutes nearly half of the atoms in proteins, but how they contribute to protein function in these complex structures has been less clear. H.....»»
New structures offer insight into how a bacterial motor powers bacterial chemotaxis, a key infectious process
Bacteria existed for millennia before humans and have been infecting us from the beginning. Although we can treat infections through pharmaceuticals, bacteria continue to become resistant to treatment thanks to their rapid evolution. Bacterial infect.....»»
Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
Freeze casting—a guide to creating hierarchically structured materials
Freeze casting is an elegant, cost-effective manufacturing technique to produce highly porous materials with custom-designed hierarchical architectures, well-defined pore orientation, and multifunctional surface structures. Freeze-cast materials are.....»»
Imaging technique shows new details of peptide structures
A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with Alzheimer's disease......»»
AI designs active pharmaceutical ingredients quickly and easily based on protein structures
A new computer process developed by chemists at ETH Zurich makes it possible to generate active pharmaceutical ingredients quickly and easily based on a protein's three-dimensional surface. The new process, detailed in Nature Communications, could re.....»»
New model extends theory of pattern formation to the nano-cosmos
A new model developed by scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) extends the theory of elastic phase separation towards nanoscopic structures. Such patterns are frequent in biological systems and also used.....»»
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......»»
