Indo-Pacific Coral Reefs Face Submergence Risk Due to Accelerating Sea-Level Rise

Indo-Pacific Coral Reefs Face Submergence Risk Due to Accelerating Sea-Level Rise

A new study indicates that over three-quarters of Indo-Pacific coral reefs may not be able to grow fast enough to keep pace with projected sea-level rise, leading to their potential submergence. Researchers from Nanyang Technological University (NTU) in Singapore found that 76% of surveyed reef sites lack the capacity to maintain upward growth under a high greenhouse gas emissions scenario. The study, published in Nature Communications, identified a critical tipping point: if relative sea level rises by more than 5.3mm per year, there is a greater than 90% chance reefs will be unable to sustain their growth. Current trends suggest this threshold could be crossed within 35 years unless significant reductions in emissions occur. Historically, coral reefs have kept pace with rising seas by building themselves upward through calcium carbonate production, which keeps them close to the surface for sunlight and wave protection. However, if sea levels rise too quickly, reefs become progressively submerged, losing ...

UT Health San Antonio Researchers Discover Liver's Circadian Clock Controls Metabolic Protein Release

UT Health San Antonio Researchers Discover Liver's Circadian Clock Controls Metabolic Protein Release

Researchers at UT Health San Antonio, part of The University of Texas at San Antonio, have made a significant discovery regarding the liver's role in coordinating metabolism. Their study, published in Nature Communications, reveals that the liver's internal circadian clock precisely controls the timing of when metabolism-regulating proteins are released. This means that the liver sends signals to other organs, such as fat tissue, on a specific daily schedule, rather than randomly. The research found that many of these proteins adhere to a precise daily release schedule. Kevin Koronowski, PhD, an assistant professor in the Department of Biochemistry and Structural Biology, explained that nearly every cell with a nucleus has its own molecular clock, and the study aims to understand how these cellular clocks coordinate their activities. Christopher Litwin, a PhD student in Koronowski’s lab, noted that while it was known the liver secretes some proteins, the detailed timing and mechanism of their release were ...

New Research Uncovers Secret Behind Narwhal Tusk's Straight Growth

New Research Uncovers Secret Behind Narwhal Tusk's Straight Growth

International researchers have discovered the unique structural secret behind the narwhal's unusually straight tusk. Published in the journal Nature Communications, the study reveals that the tusk, which can grow up to three meters long, maintains its straight form due to two opposing spirals within its structure. Study author Henrik Birkedal from Aarhus University in Denmark explained that while the outer layer of cementum has a left-handed spiral, the inner layer of dentine contains a right-handed spiral. This counter-rotating design, similar to how some molecules are structured, allows the tusk to grow perfectly straight despite its spiraled appearance. The project involved collaboration with biologists from Greenland and physicists from Sweden, utilizing advanced imaging techniques akin to CT scans to analyze the tusk's molecular composition.

Researchers Identify Submillimeter Brain Nuclei Involved in Risky Decision-Making

Researchers Identify Submillimeter Brain Nuclei Involved in Risky Decision-Making

A collaborative study by researchers at National Taiwan University and the University of Illinois at Urbana-Champaign has identified submillimeter gray matter nuclei in the human brain that are involved in distinct stages of information processing during rapid, high-stakes decision-making. Published in Nature Communications, the study utilized a 7-Tesla (7T) ultra-high-field magnetic resonance imaging (MRI) system to overcome the spatial resolution limitations of conventional scanners. This allowed for an unprecedented look at the functional activity of mesoscale brain structures, ranging from hundreds of microns to one millimeter in size. The researchers found that when high stakes were involved, the locus coeruleus signaled the frontal cortex to allocate heightened neural resources. They also observed that the ventral tegmental area/substantia nigra (VTA/SN) and nucleus accumbens (NAcc) differentiated gains from losses, and identified a novel functional role for gray matter bridges (GMBs) in signaling wh...

3D X-ray imaging unlocks the secrets of the narwhal's spiral tusk

By Will Dunham Aug 20 (Reuters) - In the Middle Ages, narwhal tusks were sold as unicorn horns blessed with magical powers such as neutralizing poisons and curing diseases — prized possessions of monarchs and nobles worth more than their weight in gold.

Wild Mice Identified as Reservoirs for Antibiotic Resistance Genes on Farms

Wild Mice Identified as Reservoirs for Antibiotic Resistance Genes on Farms

New research published in 'Nature Communications' reveals that wild mice on farms serve as significant reservoirs for antibiotic resistance genes (ARGs). A team led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Max Delbrück Center analyzed gut microorganisms from 875 wild house mice collected from German farms. They discovered that these wild mice carry approximately 50 percent of the ARGs found in livestock such as cattle, pigs, and poultry. The study correlated the presence of ARGs in mice with various environmental and host factors, including land use, farming practices, livestock density, and the mice's own characteristics. The intensity of livestock farming was found to play a decisive role in the transfer of these resistance genes into the mice's microbiome. This finding indicates that antibiotic resistance is not confined to clinical or agricultural settings but extends into wildlife populations.

Princeton University Research Reveals Music Activates Brain Networks for Imagination and Meaning Similar to Spoken Narratives

Princeton University Research Reveals Music Activates Brain Networks for Imagination and Meaning Similar to Spoken Narratives

Researchers at Princeton University have published a study in Nature Communications demonstrating that music activates brain networks associated with imagination and meaning in a manner similar to spoken narratives. The study utilized fMRI scans on participants who listened to unfamiliar instrumental music and spoken stories. After each excerpt, participants described their imagined narratives. The fMRI results indicated that imaginative and meaning-making networks were similarly engaged by both music and speech. Furthermore, varied listeners reported shared associations to the same unfamiliar musical excerpts, with an average of 71% matching a 'consensus' story for each piece of music. Matched excerpts of speech and music that triggered similar imagined stories also evoked similar patterns in the same brain regions, including auditory areas and the higher-level default mode network, which is crucial for imagination, memory, and meaning.

University of Rochester Researchers Develop Advanced Time-Gating Imaging System for Deep Tissue and Dense Fog

University of Rochester Researchers Develop Advanced Time-Gating Imaging System for Deep Tissue and Dense Fog

Researchers at the University of Rochester have developed a new, lower-cost imaging system capable of seeing through challenging environments such as deep tissue and dense fog. This system addresses limitations of existing near-infrared imaging technologies, which often struggle with scattering effects in such conditions and rely on expensive specialized detectors. The new technology utilizes inexpensive silicon-based detectors and quickly converts near-infrared light to visible light, producing clearer images. The core of this innovation is a time-gating technique, refined over a decade by the laboratory of Robert Boyd, the William F. Krupke Distinguished Professor in Optics. This technique functions like a camera shutter, using ultrafast bursts of light to allow infrared photons through a gate for only about a picosecond. The gate itself is a thin film made of indium tin oxide, which converts the near-infrared photons into visible light in real-time. The research, led by Yang Xu, was published in Nature ...
