Published Recovering tropical forests offset just one quarter of carbon emissions from new tropical deforestation and forest degradation


A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.
Published Neolithic ceramics reveal dairy processing from milk of multiple species


A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.
Published Humans are leaving behind a 'frozen signature' of microbes on Mount Everest


Thanks to technological advances in microbial DNA analysis, researchers have discovered that mountaineers' boots aren't the only things leaving footprints on the world's tallest mountain. When someone sneezes on Everest, their germs can last for centuries.
Published Lasers and chemistry reveal how ancient pottery was made -- and how an empire functioned


Peru's first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE. The pottery they left behind gives archaeologists clues as to how the empire functioned. In a new study researchers showed that rather than using 'official' Wari pottery imported from the capital, potters across the empire were creating their own ceramics, decorated to emulate the traditional Wari style. To figure it out, the scientists analyzed the pottery's chemical make-up, with help from laser beams.
Published Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought


A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
Published Study shows how biodiversity of coral reefs around the world changes with depth


Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Minke whales are as small as a lunge-feeding baleen whale can be


A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Arctic climate modelling too conservative


Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts say.
Published Surprising similarities in stone tools of early humans and monkeys


Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.
Published Existential threats to the iconic Nile River Delta


Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to water-borne contaminants.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems


An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish


An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Arctic river channels changing due to climate change



A team of international researchers have found that the rivers in Arctic Canada and Alaska are not behaving as expected in response to the warming climate. The study focused on large rivers in the region and their movement through permafrost terrain. Their findings highlight the impact of atmospheric warming on these vital waterways.
Published Life in the smoke of underwater volcanoes


Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.
Published How climate change threatens Asia's water tower



Tibet is known as the 'Water Tower of Asia,' providing water to about 2 billion people and supporting critical ecosystems in High Mountain Asia and the Tibetan Plateau, where many of the largest Asian river systems originate. This region is also one of the areas most vulnerable to the compounding effects of climate change and human activities. Researchers are identifying policy changes that need to happen now to prepare for the future impacts projected by climate models.
Published To help dry forests, fire needs to be just the right intensity, and happen more than once


Research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect -- unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn't very good at helping forest landscapes return to their historical, more fire-tolerant conditions.
Published Plant roots fuel tropical soil animal communities


A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.
Published Can artificial intelligence help find life on Mars or icy worlds?


Researchers have mapped the sparse life hidden away in salt domes, rocks and crystals at Salar de Pajonales at the boundary of the Chilean Atacama Desert and Altiplano. Then they trained a machine learning model to recognize the patterns and rules associated with their distributions so it could learn to predict and find those same distributions in data on which it was not trained. In this case, by combining statistical ecology with AI/ML, the scientists could locate and detect biosignatures up to 87.5 percent of the time and decrease the area needed for search by up to 97 percent.
Published Drones detect moss beds and changes to Antarctica climate


Researchers are using drones with highly advanced sensors and AI to map large areas and to study changes to Antarctica's climate.
Published Phone-based measurements provide fast, accurate information about the health of forests


Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.
