                    <title>Titan and Pluto exhibit the same mysterious spectral feature—and researchers can&#039;t figure out its origin</title>
                    <description>Researchers are constantly sifting through new spectral data gathered by powerful telescopes, like the James Webb Space Telescope (JWST). Most of the time, when they identify spectral features—specific absorption or emission lines from different types of light gathered from a planet, moon or star—these features are known to be caused by certain atoms or molecules. For example, the emission line at 426.7 nanometers is known to come from singly ionized carbon, representing a specific atomic transition between energy states of a carbon ion.</description>

                    <description>Sloths are the slowest mammals on the planet, but living in dense jungles has made them notoriously difficult to study. For the first time, scientists have now sequenced and analyzed the two-toed sloth genome and revealed the genetics behind its extremely slow metabolism.</description>

                    <title>Possible dark matter-deficient twins discovered in the Fornax Cluster</title>
                    <description>Astronomers have identified a possible new example of one of the universe&#039;s strangest galaxy types: galaxies that appear to contain little or no dark matter. The newly studied pair, FCC 224 and FCC 240, on the outskirts of the Fornax Cluster, share several unusual traits with the only known pair of controversial dark-matter-deficient galaxies. The findings were uploaded to the arXiv preprint server on May 22.</description>

                    <description>Cities around the world are planting more trees to cope with rising urban heat. But our research shows trees alone are often not enough. In some cases, the wrong kind of greening can even make streets feel less comfortable on a hot day.</description>

                    <description>For years, scientists studying bowhead whales have relied on a simple idea: if a whale makes a long, square or U-shaped dive, it&#039;s feeding time. A new study demonstrates that assumption may not hold water.</description>

This is especially true for optical biosensing, where scientists try to detect extremely small changes caused by biomolecules binding to a sensor surface.</description>

                    <description>A research team from the Institut Català de Paleontologia Miquel Crusafont (ICP-CERCA) has led the paleohistological study of Ampelomeryx ginsburgi, a giraffomorph ruminant from the Middle Miocene recovered at the Els Casots site (Catalonia, Spain). Through microscopic analysis of bone tissues, the researchers were able to determine that this peculiar animal reached skeletal maturity at three years of age, while reproductive maturity began around the second year.</description>

                    <description>A study conducted in the Brazilian state of Amazonas has demonstrated that small amounts of Amazonian dark earth (ADE)—an anthropogenic soil created by ancient Amazonian populations—can increase the height and diameter of the pink trumpet tree (Handroanthus avellanedae) by up to 55% and 88%, respectively. This tree also occurs in the Atlantic Forest. The research is published in the journal BMC Ecology and Evolution.</description>

                    <description>Researchers at the Indian Institute of Science (IISc) have implemented an advanced microscopy technique to visualize multiple biomolecules inside the nucleus of a cancer cell simultaneously at incredibly high resolution. The biomolecules they visualized include critical components of the cell&#039;s transcription machinery and proteins that provide structural support to the nucleus—providing one of the first detailed maps of nuclear organization.</description>

                    <title>Stem cell embryo model grows yolk sac without hypoblasts or gene editing</title>
                    <description>For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation. The models were made at University of Michigan Engineering. Researchers at the Chinese Academy of Sciences provided monkey embryo data to help confirm that the Michigan team was indeed seeing a yolk-sac-like structure in their models. The work is published in the journal Nature Cell Biology.</description>

                    <description>A joint theoretical study by the University of Innsbruck and Zhejiang University has uncovered the microscopic origin of a striking quantum phenomenon: a periodically driven gas of ultracold atoms that simply refuses to heat up, defying classical expectations.</description>

                    <description>On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn&#039;s largest moon, Titan, a similar mild wind would kick up 10-foot-tall waves. This otherworldly behavior is one prediction from a new wave model developed by scientists at MIT. The model is the first to capture the full dynamics of waves and what it takes to whip them up under different planetary conditions.</description>

                    <description>Alena Tensor is a relatively new mathematical approach that allows for arbitrary curving and straightening of analyzed spacetimes. As it turns out, generalizing this model to all known fields and fully describing matter, spontaneously gives rise to the phenomena known from research on dark matter and dark energy.</description>

                    <description>For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of countless experiments and agreeing with observations down to the smallest known precisions. Yet, some high-intensity scales of QED remain unexplored, prompting some to wonder if quantum computers could deal with these scales&#039; inherent complexity.</description>

                    <description>How can magma buried 5, 10, or even 15 km underground be detected without any surface indicators? The answer lies in ambient noise tomography, a technique that analyzes natural ground vibrations with high precision. A team from the University of Geneva (UNIGE), the Institute of Geosciences and Earth Resources (CNR-IGG), and the National Institute of Geophysics and Volcanology (INGV) has identified a vast reservoir containing approximately 6,000 km3 of magma beneath Tuscany.</description>

Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside these outer solar system bodies.</description>

                    <description>A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The team used gravitational-wave data from pulsar timing arrays to probe galactic centers that are otherwise impossible to observe directly.</description>

                    <description>Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it&#039;s more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations of high-energy particle collisions, they have developed a more accurate method for estimating the impact of calculations that are not performed.</description>

                    <description>For the first time in Brazil, researchers have identified a field of tektites. These are natural glasses formed by the high-energy impact of extraterrestrial bodies against Earth&#039;s surface. These structures, named geraisites in honor of the Brazilian state of Minas Gerais, where they were first discovered, constitute a new strewn field. This expands the incomplete record of impacts in South America.</description>

                    <description>Monarch butterflies have always been remarkably resilient. Every fall, these delicate orange-and-black travelers set out on a journey so improbable it borders on myth, flying some three thousand kilometers from Canadian fields all the way to Mexico&#039;s mountain forests, their overwintering grounds. They&#039;ve been weathering habitat loss, extreme weather and pesticides, but new research from the University of Ottawa suggests a new snag in their epic trek. The culprit? Nectar. Turns out, their main food source isn&#039;t what it used to be.</description>
