Published How consciousness in animals could be researched
(via sciencedaily.com) Animal consciousness should not be thought of as a light switch, which can be on or off, philosophers say. They advocate a different approach.
Published Bald eagles aren't fledging as many chicks due to avian influenza
(via sciencedaily.com) Bald eagles are often touted as a massive conservation success story due to their rebound from near extinction in the 1960s. But now a highly infectious virus may put that hard-fought comeback in jeopardy. New research showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers of mating pairs of bald eagles.
Published U.S. birds' Eastern, Western behavior patterns are polar opposites
(via sciencedaily.com) Scientists have established what could be considered a baseline map of annual avian functional and species diversity patterns in the U.S., finding that functional diversity patterns in the West, where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high.
Published Researchers provide proof of the helical coiling of condensed chromosomes
(via sciencedaily.com) Original source In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture sequencing. Still, the direct visualization of the coiled chromonema confirming the helical model was lacking. Now, an international research team provides the direct proof of the helical coiling of condensed chromatids via super-resolution microscopy of specifically labelled chromonema regions.
Published Bronze Age well contents reveal the history of animal resources in Mycenae, Greece
(via sciencedaily.com) Original source A large Bronze Age debris deposit in Mycenae, Greece provides important data for understanding the history of animal resources at the site, according to a new study.
Published Prehistoric sea monster may have been shorter, stouter, than once believed
(via sciencedaily.com) A big fish story? Maybe so: The greatest sea monster of the Devonian Period (Dunkleosteus terrelli) may be getting downsized. A new article contents that the famous sea monster of the Age of Fishes may not have neared 30-feet in length, as long believed, but topped off at maybe 13 feet. The new assertion brings attention to a famously fierce looking armored fish from 360 million years ago -- and maybe a new debate.
Published Mulching time of forest meadows influences insect diversity
(via sciencedaily.com) Researchers have examined how mulching at different times affects insect flower-visitors and larvae.
Published Artificial Intelligence from a psychologist's point of view
(via sciencedaily.com) Researchers test cognitive abilities of the language model GPT-3.
Published Reaching like an octopus: A biology-inspired model opens the door to soft robot control
(via sciencedaily.com) Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.
Published Theory can sort order from chaos in complex quantum systems
(via sciencedaily.com) Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on photosynthesis models.
Published AI analyzes cell movement under the microscope
(via sciencedaily.com) Using artificial intelligence (AI), researchers can now follow cell movement across time and space. The method could be very helpful for developing more effective cancer medications.
Published Scientific AI's 'black box' is no match for 200-year-old method
(via sciencedaily.com) A new study finds that a 200-year-old technique called Fourier analysis can reveal crucial information about how the form of artificial intelligence called deep neural networks (DNN) learn to perform tasks involving complex physics. Researchers discovered the technique can directly connect what a DNN has learned to the physics of the complex system the DNN is modeling.
Published Researchers take a step toward novel quantum simulators
(via sciencedaily.com) If scaled up successfully, the team's new system could help answer questions about certain kinds of superconductors and other unusual states of matter.
Published COVID calculations spur solution to old problem in computer science
(via sciencedaily.com) A mathematician was keen to forecast the evolution of the COVID epidemic. Instead, he ended up solving a problem which had troubled computer scientists for decades.
Published Modelling the collective movement of bacteria
(via sciencedaily.com) A new paper presents a mathematical model for the motion of bacteria that includes cell division and death, the basic ingredients of the cell cycle.
Published A peculiar protected structure links Viking knots with quantum vortices
(via sciencedaily.com) Original source Mathematical analysis identifies a vortex structure that is impervious to decay.
Published Revealing the complex magnetization reversal mechanism with topological data analysis
(via sciencedaily.com) The reliability of data storage and writing speed in advanced magnetic devices depend on drastic, complex changes in microscopic magnetic domain structures. However, it is extremely challenging to quantify these changes, limiting our understanding of magnetic phenomena. To tackle this, researchers developed, using machine learning and topology, an analysis method that quantifies the complexity of the magnetic domain structures, revealing hidden features of magnetization reversal that are hardly seen by human eyes.
Published Finding simplicity within complexity
(via sciencedaily.com) With the theory that for every action, even those seemingly complex and random, there is a math problem that describes it, a researcher is publishing a new formula that helps find that equation quickly. Yes, he's speeding up science.
Published Math approach may make drug discovery more effective, efficient
(via sciencedaily.com) Researchers have devised a computer-based platform for drug discovery that could make the process more effective, more efficient and less costly.
Published Using math to better treat cancer
(via sciencedaily.com) Researchers have identified a new method for scheduling radiation therapy that could be as much as 22 percent more effective at killing cancer cells than current standard radiation treatment regimens.
