Published Protecting endangered monkeys from poachers, habitat loss
(via sciencedaily.com) Original source The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.
Published Discovery of mechanism plants use to change seed oil could impact industrial, food oils
(via sciencedaily.com) Original source Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.

Published When does a conductor not conduct?
(via sciencedaily.com) Original source A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material create an unusual electrically-insulating phase in which electrons are 'frozen'. By reducing the population of electrons, the authors are able to unfreeze the remaining electrons, allowing for controlled transitions between insulating and electrically-conductive phases: the key to the on-off binary operations of classical computing.
Published Getting dynamic information from static snapshots
(via sciencedaily.com) Original source Researchers have created TopicVelo, a powerful new method of using the static snapshots from scRNA-seq to study how cells and genes change over time. This will help researchers better study how embryos develop, cells differentiate, cancers form, and the immune system reacts.
Published Ancient Maya blessed their ballcourts
(via sciencedaily.com) Original source Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.
Published Barley plants fine-tune their root microbial communities through sugary secretions
(via sciencedaily.com) Original source Different types of barley recruit distinct communities of soil microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study.
Published Climate change could become the main driver of biodiversity decline by mid-century
(via sciencedaily.com) Original source Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century.
Published A shortcut for drug discovery
(via sciencedaily.com) Original source For most human proteins, there are no small molecules known to bind them chemically (so called 'ligands'). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines. Researchers at CeMM, in a collaboration with Pfizer, have now leveraged and scaled a method to measure the binding activity of hundreds of small molecules against thousands of human proteins. This large-scale study revealed tens of thousands of ligand-protein interactions that can now be explored for the development of chemical tools and therapeutics. Moreover, powered by machine learning and artificial intelligence, it allows unbiased predictions of how small molecules interact with all proteins present in living human cells. These groundbreaking results have been published in the journal Science (DOI: 10.1126/science.adk5864), and all generated data and models are freely available for the scientific community.
Published Nanomaterial that mimics proteins could be basis for new neurodegenerative disease treatments
(via sciencedaily.com) Original source A newly developed nanomaterial that mimics the behavior of proteins could be an effective tool for treating Alzheimer's and other neurodegenerative diseases. The nanomaterial alters the interaction between two key proteins in brain cells -- with a potentially powerful therapeutic effect.
Published The longer spilled oil lingers in freshwater, the more persistent compounds it produces
(via sciencedaily.com) Original source Oil is an important natural resource for many industries, but it can lead to serious environmental damage when accidentally spilled. While large oil spills are highly publicized, every year there are many smaller-scale spills into lakes, rivers and oceans. The longer that oil remains in freshwater, the more chemical changes it undergoes, creating products that can persist in the environment.
Published Deer are expanding north, and that's not good for caribou
(via sciencedaily.com) Original source In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published The secret to saving old books could be gluten-free glues
(via sciencedaily.com) Original source 'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators restore and preserve treasured tomes for future generations.
Published Unveiling the lionfish invasion in the Mediterranean Sea
(via sciencedaily.com) Original source Researchers have published a comprehensive study on the invasion of lionfish in the Mediterranean Sea, highlighting a rapid spread and the potential ecological impacts. The research shows the lionfish species Pterois miles has significantly expanded its territory in the Mediterranean since the invasion began around ten years ago. The invasive species has established presence in the eastern Mediterranean, with observations now extending to colder waters previously thought to be unsuitable for the species.
