Published Scientists uncover ocean's intricate web of microbial interactions across depths
(via sciencedaily.com) Original source An international team of scientists has uncovered the ocean's intricate web of microbial interactions across depths. Their research provides crucial insights into the functioning of ocean ecosystems.
Published Generating stable qubits at room temperature
(via sciencedaily.com) Original source Quantum bits, or qubits, can revolutionize computing and sensing systems. However, cryogenic temperatures are required to ensure the stability of qubits. In a groundbreaking study, researchers observed stable molecular qubits of four electron spins at room temperature for the first time by suppressing the mobility of a dye molecule within a metal-organic framework. Their innovative molecular design opens doors to materials that could drive the development of quantum technologies capable of functioning in real-world conditions.
Published First direct imaging of small noble gas clusters at room temperature
(via sciencedaily.com) Original source Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental research in condensed matter physics and applications in quantum information technology. The key to this breakthrough was the confinement of noble gas atoms between two layers of graphene.
Published Toxic algae blooms: Study assesses potential health hazards to humans
(via sciencedaily.com) Original source Water samples from 20 sites were tested using a panel of immortalized human cell lines corresponding to the liver, kidney and brain to measure cytotoxicity. Results show that each control toxin induced a consistent pattern of cytotoxicity in the panel of human cell lines assayed. Known toxins were seen only during blooms. Because cell toxicity was seen in the absence of blooms, it suggests that there might be either emergent toxins or a combination of toxins present at those times. Findings suggest that other toxins with the potential to be harmful to human health may be present in the lagoon.
Published Focus on biological processes does not capture the whole picture
(via sciencedaily.com) Original source The ocean plays a crucial role in the storage of carbon dioxide (CO2). The so-called marine biological carbon pump is an important research topic in this context. However a key component is often overlooked. Colleagues outline why it is insufficient to focus solely on biological processes when investigating the accumulation of CO2 in the ocean by the biological carbon pump.
Published A red knot's character is formed in first year of life
(via sciencedaily.com) Original source In any group of red knots, respective individuals exhibit a remarkable array of distinct character types. Birds with an exploratory character are motivated to investigate their environment and readily explore unfamiliar areas. Meanwhile, birds with inactive character types are content to remain in familiar territory. Interestingly, the birds do not appear to hatch with predetermined character types. Their characters are formed later, in the first year of life, as a result of their experiences in the Wadden Sea.
Published Observing macroscopic quantum effects in the dark
(via sciencedaily.com) Original source Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.
Published In hot water: Coral resilience in the face of climate change
(via sciencedaily.com) Original source Researchers have been studying the effects of climate change on coral reefs. Monitoring two coral species off the coast of Hawaii, one team found that local adaptations in response to near-severe heat stress allowed certain populations to endure such events.
Published Acidity of Antarctic waters could double by century's end, threatening biodiversity
(via sciencedaily.com) Original source Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss.
Published Researchers demonstrate that quantum entanglement and topology are inextricably linked
(via sciencedaily.com) Original source Researchers have demonstrated the remarkable ability to perturb pairs of spatially separated yet interconnected quantum entangled particles without altering their shared properties.
Published Stranger than friction: A force initiating life
(via sciencedaily.com) Original source As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.
Published New study uses machine learning to bridge the reality gap in quantum devices
(via sciencedaily.com) Original source A study has used the power of machine learning to overcome a key challenge affecting quantum devices. For the first time, the findings reveal a way to close the 'reality gap': the difference between predicted and observed behavior from quantum devices.
Published Protecting coral 'nurseries' as important as safeguarding established coral reefs
(via sciencedaily.com) Original source New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.
Published Fastest swimming insect could inspire uncrewed boat designs
(via sciencedaily.com) Original source Whirligig beetles, the world's fastest-swimming insect, achieve surprising speeds by employing a strategy shared by fast-swimming marine mammals and waterfowl, according to a new study that rewrites previous explanations of the physics involved.
Published The snail or the egg?
(via sciencedaily.com) Original source Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research has shed new light on the genetic changes that allow organisms to make the switch.
Published Male southern elephant seals are picky eaters
(via sciencedaily.com) Original source New research suggests these large marine mammals are extremely fussy and only eat their favorite foods.
Published The choreography connecting kelp forests to the beach
(via sciencedaily.com) Original source A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.
Published Vitamin discovered in rivers may offer hope for salmon suffering from thiamine deficiency disease
(via sciencedaily.com) Original source Researchers have discovered vitamin B1 produced by microbes in rivers, findings that may offer hope for vitamin-deficient salmon populations.
Published 'Giant' predator worms more than half a billion years old discovered in North Greenland
(via sciencedaily.com) Original source Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.
Published Functional semiconductor made from graphene
(via sciencedaily.com) Original source Researchers have created the first functional semiconductor made from graphene, a single sheet of carbon atoms held together by the strongest bonds known. The breakthrough throws open the door to a new way of doing electronics.
