Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows



The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published New deep-sea worm discovered at methane seep off Costa Rica



Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.
Published Using light to precisely control single-molecule devices



Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Published New method measures the 3D position of individual atoms



Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Published Shortcut to Success: Toward fast and robust quantum control through accelerating adiabatic passage



Researchers achieved the acceleration of adiabatic evolution of a single spin qubit in gate-defined quantum dots. After the pulse optimization to suppress quasistatic noises, the spin flip fidelity can be as high as 97.5% in GaAs quantum dots. This work may be useful to achieve fast and high-fidelity quantum computing.
Published Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era



Fossils of a strange new species of marine lizard with dagger-like teeth that lived 66 million years ago, show a dramatically more biodiverse ocean ecosystem to what we see today.
Published One way to improve a fusion reaction: Use weaknesses as strengths



Scientists are embracing imperfection, using less-than-ideal magnetic fields to make the plasma more manageable.
Published Spontaneous curvature the key to shape-shifting nanomaterials



Inspired by nature, nanotechnology researchers have identified 'spontaneous curvature' as the key factor determining how ultra-thin, artificial materials can transform into useful tubes, twists and helices.
Published Network of quantum sensors boosts precision



Quantum sensor technology promises even more precise measurements of physical quantities. A team has now compared the signals of up to 91 quantum sensors with each other and thus successfully eliminated the noise caused by interactions with the environment. Correlation spectroscopy can be used to increase the precision of sensor networks.
Published Tests show high-temperature superconducting magnets are ready for fusion



A comprehensive study of high-temperature superconducting magnets confirms they meet requirements for an economic, compact fusion power plant.
Published Orcas demonstrating they no longer need to hunt in packs to take down the great white shark



An orca (killer whale) has been observed, for the first-ever time, individually consuming a great white shark -- and within just two minutes.
Published Convergent evolution of algal CO2-fixing organelles



Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.
Published AI-enabled atomic robotic probe to advance quantum material manufacturing



Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.
Published Scientists make nanoparticles dance to unravel quantum limits



The question of where the boundary between classical and quantum physics lies is one of the longest-standing pursuits of modern scientific research and in new research, scientists demonstrate a novel platform that could help us find an answer.
Published Umbrella for atoms: The first protective layer for 2D quantum materials



As silicon-based computer chips approach their physical limitations in the quest for faster and smaller designs, the search for alternative materials that remain functional at atomic scales is one of science's biggest challenges. In a groundbreaking development, researchers have engineered a protective film that shields quantum semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach.
Published Better neutron mirrors can reveal the inner secrets of matter



Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS. The improved mirror has been developed by coating a silicon plate with extremely thin layers of iron and silicon mixed with boron carbide.
Published When the music changes, so does the dance: Controlling cooperative electronic states in Kagome metals



Playing a different sound track is, physically speaking, only a minute change of the vibration spectrum, yet its impact on a dance floor is dramatic. People long for this tiny trigger, and as a salsa changes to a tango completely different collective patterns emerge. For such a tiny stimulus to have an effect, the crowd needs to know more than just one dance. Electrons in metals tend to show only one behavior at zero temperature, when all kinetic energy is quenched.
Published Slimming down a colossal fossil whale



A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus



Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.
Published Avian influenza virus is adapting to spread to marine mammals



Avian influenza virus H5N1 has adapted to spread between birds and marine mammals, finds a new study.
