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 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.
Published New pipeline makes valuable organic acid from plants -- saving money and emissions
(via sciencedaily.com) Original source In a breakthrough for environmentally friendly chemical production, researchers have developed an economical way to make succinic acid, an important industrial chemical, from sugarcane. The team has created a cost-effective, end-to-end pipeline for this valuable organic acid by engineering a tough, acid-tolerant yeast as the fermenting agent, avoiding costly steps in downstream processing. Succinic acid is a widely used additive for food and beverages and has diverse applications in agricultural and pharmaceutical products. This same pipeline can be used to produce other industrially important organic acids from crops rather than petroleum-based processes, significantly reducing greenhouse gas emissions.
Published Gut bacteria found in wild wolves may be key to improving domestic dogs' health
(via sciencedaily.com) Original source Gut microbes found in wild wolves may be the key to alleviating a debilitating gastrointestinal condition common to domestic dogs.
Published When cells go boom: Study reveals inflammation-causing gene carried by millions
(via sciencedaily.com) Original source Researchers have found that a genetic change that increases the risk of inflammation, through a process described as ‘explosive’ cell death, is carried by up to 3% of the global population.
Published How new plant cell walls change their mechanical properties after cell division
(via sciencedaily.com) Original source Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the growth of plant organs.
Published DNA from discarded whale bones suggests loss of genetic diversity due to commercial whaling
(via sciencedaily.com) Original source Commercial whaling in the 20th century decimated populations of large whales but also appears to have had a lasting impact on the genetic diversity of today’s surviving whales, new research shows.
Published Preventing spread of parasitic DNA in our genomes
(via sciencedaily.com) Original source Researchers have identified a new enzyme called PUCH, which plays a key role in preventing the spread of parasitic DNA in our genomes. These findings may reveal new insights into how our bodies detect and fight bacteria and viruses to prevent infections.
Published Swap red meat for Quorn protein to improve heart health and reduce waist circumference, study finds
(via sciencedaily.com) Original source People looking to reduce their cholesterol and trim fat from around their waist could try swapping meat for Quorn protein, according to the findings from a new study, which saw positive effects in both areas in just two weeks.
Published Water makes all the difference
(via sciencedaily.com) Original source Water is a major driving force in the formation of separate reaction compartments within cells.
Published A hygiene program for chromosomes
(via sciencedaily.com) Original source Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system.
Published Distributed workload in the fly brain
(via sciencedaily.com) Original source To distinguish motion patterns, a neuronal computation is performed three times in a row.
Published A more effective experimental design for engineering a cell into a new state
(via sciencedaily.com) Original source A new machine-learning approach helps scientists more efficiently identify the optimal intervention to achieve a certain outcome in a complex system, such as genome regulation, requiring far fewer experimental trials than other methods.
Published Researchers studied thousands of fertility attempts hoping to improve IVF
(via sciencedaily.com) Original source By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization.
