Published Vulnerability of England's only resident bottlenose dolphins



New research has provided a detailed examination of England's bottlenose dolphin population's existence and the challenges it faces from human activities and environmental factors on a daily basis.
Published Landscape dynamics determine the evolution of biodiversity on Earth



A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
Published Quantum tool opens door to uncharted phenomena



Scientists have developed a new tool for the measurement of entanglement in many-body systems and demonstrated it in experiments. The method enables the study of previously inaccessible physical phenomena and could contribute to a better understanding of quantum materials.
Published Researchers engineer a material that can perform different tasks depending on temperature



Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
Published Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico



Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.
Published Nextgen computing: Hard-to-move quasiparticles glide up pyramid edges



A new kind of 'wire' for moving excitons could help enable a new class of devices, perhaps including room temperature quantum computers.
Published Unlocking the secrets of cells, with AI



Researchers have developed a new program that provides a more accurate understanding of the peptide sequences in cells. The researchers use machine learning to help analyze the makeup of unfamiliar cells, which could lead to more personalized medicine in the treatment of cancer and other serious diseases.
Published Defending your voice against deepfakes



Computer scientists have developed AntiFake, a tool to protect voice recordings from unauthorized speech synthesis.
Published Giant sea salt aerosols play major role in Hawai'i's coastal clouds, rain



A new study from atmospheric scientists revealed that the coastline can produce up to five times the concentration of giant sea salt aerosols compared to the open ocean and that coastal clouds may contain more of these particles than clouds over the open ocean -- affecting cloud formation and rain around the Hawaiian Islands.
Published Measuring long-term heart stress dynamics with smartwatch data



Biomedical engineers have developed a method using data from wearable devices such as smartwatches to digitally mimic an entire week's worth of an individual's heartbeats. The new 'digital twins' computational framework captures personalized arterial forces over 700,000 heartbeats to better predict risks of heart disease and heart attack. The advance is an important step toward evaluating the risks of heart disease or heart attack over months to years.
Published Scientists find both potential threats and promising resources in the thriving colonies of bacteria and fungi on ocean plastic trash



Scientists have found both potential threats and promising resources in the thriving colonies of bacteria and fungi on plastic trash washed up on shores.
Published Immersive engagement in mixed reality can be measured with reaction time



In the real world/digital world cross-over of mixed reality, a user's immersive engagement with the program is called presence. Now, researchers have identified reaction time as a potential presence measurement tool. Their findings have implications for calibrating mixed reality to the user in real time.
Published Deoxygenation levels similar to today's played a major role in marine extinctions during major past climate change event



Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for current day ecosystems -- and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role in ecosystem disruption and extinctions in marine environments during the Triassic--Jurassic mass extinction, a major extinction event that occurred around 200 million years ago. Surprisingly however, the study shows that the global extent of euxinia (an extreme form of de-oxygenated conditions) was similar to the present day.
Published How heat can be used in computing



Physicists have demonstrated that, combining specific materials, heat in technical devices can be used in computing. Their discovery is based on extensive calculations and simulations. The new approach demonstrates how heat signals can be steered and amplified for use in energy-efficient data processing.
Published Pioneering research method reveals bluefin tuna's fate



The Mediterranean spawning grounds of Bluefin tuna -- the largest tuna and one of the most powerful fish in the sea -- are under threat, due to rising sea temperatures. A pioneering research method to decode bluefin 'otoliths' (a stony tissue found in their ear) has determined the threshold sea temperature at which bluefin thrive to be 28 degrees Celsius.
Published The Fens of eastern England once held vast woodlands



The Fens of eastern England, a low-lying, extremely flat landscape dominated by agricultural fields, was once a vast woodland filled with huge yew trees, according to new research. Scientists have studied hundreds of tree trunks, dug up by Fenland farmers while ploughing their fields. The team found that most of the ancient wood came from yew trees that populated the area between four and five thousand years ago.
Published Separating out signals recorded at the seafloor



Research shows that variations in pyrite sulfur isotopes may not represent the global processes that have made them such popular targets of analysis and interpretation. A new microanalysis approach helps to separate out signals that reveal the relative influence of microbes and that of local climate.
Published How shipwrecks are providing a refuge for marine life



New research has highlighted how the estimated 50,000 wrecks around the UK coastline are protecting the seabed, and the species inhabiting it, in areas still open to bottom-towed fishing.
Published Predicting the fate of shallow coastal ecosystems for the year 2100



A new study of shallow-water ecosystems estimates that, by 2100, climate change and coastal land usage could result in significant shrinkage of coral habitats, tidal marshes, and mangroves, while macroalgal beds remain stable and seagrass meadows potentially expand.
Published Hybrid transistors set stage for integration of biology and microelectronics



Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
