Published Consistent metabolism may prove costly for insects in saltier water
(via sciencedaily.com) Original source Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater invertebrates (like mollusks and crustaceans) thrive.
Published How male mosquitoes compensate for having only one X chromosome
(via sciencedaily.com) Researchers have discovered the master regulator responsible for balancing the expression of X chromosome genes between males and females in the malaria mosquito. This discovery helps scientists better understand the evolution of the epigenetic mechanisms responsible for equalizing gene expression between the sexes. The findings may contribute to the development of new ways to prevent the spread of malaria.
Published Natural GM crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors
(via sciencedaily.com) Original source Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.
Published Twisted science: New quantum ruler to explore exotic matter
(via sciencedaily.com) Original source Researchers have developed a 'quantum ruler' to measure and explore the strange properties of multilayered sheets of graphene, a form of carbon. The work may also lead to a new, miniaturized standard for electrical resistance that could calibrate electronic devices directly on the factory floor, eliminating the need to send them to an off-site standards laboratory.
Published New discovery may 'unlock' the future of infectious disease and cancer treatment
(via sciencedaily.com) Original source Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and even cancer.
Published The end of genes: Routine test reveals unique divergence in genetic code
(via sciencedaily.com) Original source Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in the DNA code signalling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.
Published Plants could worsen air pollution on a warming planet
(via sciencedaily.com) Original source New research shows that plants such as oak and poplar trees will emit more of a compound called isoprene as global temperatures climb. Isoprene from plants represents the highest flux of hydrocarbons to the atmosphere after methane. Although isoprene isn’t inherently bad — it actually helps plants better tolerate insect pests and high temperatures — it can worsen air pollution by reacting with nitrogen oxides from automobiles and coal-fired power plants. The new publication can help us better understand, predict and potentially mitigate the effects of increased isoprene emission as the planet warms.
Published Shining a light on tiny, solar-powered animals
(via sciencedaily.com) Original source Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
Published New open-source method to improve decoding of single-cell data
(via sciencedaily.com) Original source Researchers have developed a new open-source computational method, dubbed Spectra, which improves the analysis of single-cell transcriptomic data. By guiding data analysis in a unique way, Spectra can offer new insights into the complex interplay between cells — like the interactions between cancer cells and immune cells, which are critical to improving immunotherapy treatments.
Published Ruffed grouse population more resilient than expected, genetic study finds
(via sciencedaily.com) Original source Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
Published Proteins roll the dice to determine bee sex
(via sciencedaily.com) Original source To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.
Published New 'Assembly Theory' unifies physics and biology to explain evolution and complexity
(via sciencedaily.com) Original source An international team of researchers has developed a new theoretical framework that bridges physics and biology to provide a unified approach for understanding how complexity and evolution emerge in nature. This new work on 'Assembly Theory' represents a major advance in our fundamental comprehension of biological evolution and how it is governed by the physical laws of the universe.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
Published Birders and AI push bird conservation to the next level
(via sciencedaily.com) Original source Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Avatars to help tailor glioblastoma therapies
(via sciencedaily.com) Original source Scientists have created a new zebrafish xenograft platform to screen for novel treatments for an aggressive brain tumor called glioblastoma, according to a new study.
Published Honeybees are more selective in their choices for nutrition than previously thought
(via sciencedaily.com) Original source An international research group examined which plants honeybees favor when collecting nectar and pollen. The choices honeybees make have an impact on their health and also on humans, as honeybees pollinate important crop plants.
Published Cats purr differently than previously thought
(via sciencedaily.com) Original source A recent investigation delivers novel insights into how cats produce their purring sounds. A special 'pad' embedded in the vocal folds might explain how cats can produce these low-frequency sounds.
Published Ancient technology turns plant-based cheese into 'something we want to eat'
(via sciencedaily.com) Original source To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Published Scientists develop 3D printing method that shows promise for repairing brain injuries
(via sciencedaily.com) Original source Researchers have produced an engineered tissue representing a simplified cerebral cortex by 3D printing human stem cells. When implanted into mouse brain slices, the structures became integrated with the host tissue. The technique may ultimately be developed into tailored repairs to treat brain injuries.
