Published Genome studies uncover a new branch in fungal evolution
(via sciencedaily.com) Original source About 600 seemingly disparate fungi that had resisted categorization have been shown to have a common ancestor, according to a a research team that used genome sequencing to give these peculiar creatures a new classification home.
Published Human evolution wasn't just the sheet music, but how it was played
(via sciencedaily.com) A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
Published A far-sighted approach to machine learning
(via sciencedaily.com) A new technique enables artificial intelligence agents to think much farther into the future when considering how their behaviors can influence the behaviors of other AI agents, toward the completion of a task. This approach improves long-term performance of cooperative or competitive AI agents.
Published A nanoscale view of bubble formation
(via sciencedaily.com) A nanoscale view of bubble formation: Using computer simulation, a research team succeeded in modeling the behavior of molecules at the liquid -- gas interface at the nanometer scale, enabling them to describe the boiling process with extreme precision. The findings could be applied to future cooling systems for microprocessors, or to the production of carbon-neutral hydrogen, known as green hydrogen.
Published Achieving a quantum fiber
(via sciencedaily.com) Researchers have successfully demonstrated the transport of two-photon quantum states of light through a phase-separated Anderson localization optical fiber.
Published Old World flycatchers' family tree mapped
(via sciencedaily.com) Original source The European robin's closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.
Published Synthetic fibers discovered in Antarctic air, seawater, sediment and sea ice as the 'pristine' continent becomes a sink for plastic pollution
(via sciencedaily.com) Microplastic fibers discovered in samples (air, seawater, sediment and sea-ice) from the last remaining pristine environment on Earth.
Published Spin correlation between paired electrons demonstrated
(via sciencedaily.com) Original source Physicists have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum dots.
Published Decrease in crucial trace element preceded ancient mass extinction
(via sciencedaily.com) A decline in the element molybdenum across the planet's oceans preceded a significant extinction event approximately 183 million years ago, new research shows.
Published Scientists convert waste paper into battery parts for smartphones and electric vehicles
(via sciencedaily.com) Scientists have developed a technique to convert waste paper, from single-use packaging and bags, and cardboard boxes, into a crucial component of lithium-ion batteries. Through a process called carbonisation which converts paper into pure carbon, the researchers turned the paper's fibers into electrodes, which can be made into rechargeable batteries that power mobile phones, medical equipment, and electric vehicles.
Published Quantum algorithms save time in the calculation of electron dynamics
(via sciencedaily.com) Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, quantum computer algorithms can already run on conventional servers that simulate a quantum computer. A team has succeeded in calculating the electron orbitals and their dynamic development using an example of a small molecule after a laser pulse excitation. In principle, the method is also suitable for investigating larger molecules that cannot be calculated using conventional methods.
Published 'Primordial super-enhancers' provide early snapshot of the mechanisms that allowed for multicellularity
(via sciencedaily.com) A new study has found that organelle-like transcriptional condensates are an ancient and flexible tool used by cells to drive rapid gene expression.
Published Glass-like shells of diatoms help turn light into energy in dim conditions
(via sciencedaily.com) A new study has revealed how the glass-like shells of diatoms help these microscopic organisms perform photosynthesis in dim conditions. A better understanding of how these phytoplankton harvest and interact with light could lead to improved solar cells, sensing devices and optical components.
Published World's oldest meal helps unravel mystery of our earliest animal ancestors
(via sciencedaily.com) The contents of the last meal consumed by the earliest animals known to inhabit Earth more than 550 million years ago has unearthed new clues about the physiology of our earliest animal ancestors, according to scientists.
Published International team observes innermost structure of quasar jet
(via sciencedaily.com) Scientists have observed the narrowing of a quasar jet for the first time by using a network of radio telescopes across the world. The results suggest that the narrowing of the jet is independent of the activity level of the galaxy which launched it.
Published Great potential for aquifer thermal energy storage systems
(via sciencedaily.com) Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground and pumped up, if needed. Researchers have now found that low-temperature aquifer thermal energy storage is of great potential in Germany. This potential is expected to grow in future due to climate change.
Published Self-organization: What robotics can learn from amoebae
(via sciencedaily.com) Researchers have developed a new model to describe how biological or technical systems form complex structures without external guidance.
Published Earth might be experiencing 7th mass extinction, not 6th
(via sciencedaily.com) Earth is currently in the midst of a mass extinction, losing thousands of species each year. New research suggests environmental changes caused the first such event in history, which occurred millions of years earlier than scientists previously realized.
Published An exoplanet atmosphere as never seen before
(via sciencedaily.com) New observations of WASP-39 b reveal a never-before-seen molecule in the atmosphere of a planet -- sulfur dioxide -- among other details.
Published Limiting global warming now can preserve valuable freshwater resource
(via sciencedaily.com) A research team has found that the Andean region of Chile could face noticeable snow loss and roughly 10% less mountain water runoff with a global warming of approximately 2.5 degrees Celsius compared to pre-industrial levels over the next three decades. The study also shows that what happens in the Andes could be a harbinger of what is to come for the California Sierra Nevada mountain range, and highlights the importance of carbon-mitigation strategies to prevent this from occurring.
