Published Understanding greenhouse gases in oil palm plantations
(via sciencedaily.com) Original source The rapid spread of oil palm plantations and associated high use of fertilizer raises concerns about the emission of nitrous oxide, a powerful greenhouse gas. A new study shows that oil palms’ photosynthesis and their response to meteorological and soil conditions play an important but still widely unexplored role in the amount of nitrous oxide produced by oil palm plantations.
Published Being a vegetarian may be partly in your genes
(via sciencedaily.com) Original source A person's genetic makeup plays a role in determining whether they can stick to a strict vegetarian diet, a new study has found. The findings open the door to further studies that could have important implications regarding dietary recommendations and the production of meat substitutes.
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 Hospital superbugs: Could one vaccine rule them all?
(via sciencedaily.com) Original source A new study shows that a single dose of the vaccine, administered in mouse models, put immune cells into 'Incredible Hulk' mode, providing rapid protection against nine different bacteria and fungi species that lurk in healthcare settings.
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 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 Wastewater detects signs of antimicrobial resistance in aged care facilities
(via sciencedaily.com) Original source A new study analyzing wastewater samples from several aged care facilities and retirement homes, has uncovered worrying signs of antimicrobial resistance (AMR), a concerning trend in aged care facilities.
Published Extreme fires and heavy rainfall driving platypuses from their homes
(via sciencedaily.com) Original source Australia's emerging pattern of severe mega bushfires and heavy rainfall may be driving platypuses from their homes, a new study has shown. Analysis of platypus DNA in rivers and creek water samples collected before and after the Black Summer 2019-2020 megafires suggest Australia's beloved semi-aquatic monotremes might be abandoning severely bushfire-affected areas for up to 18 months after a fire, especially if heavy rainfall has followed the fire.
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 Tracking the bacteria behind life-threatening sepsis in premature babies
(via sciencedaily.com) Original source A new study into sepsis in neonatal babies has uncovered the secrets of the bacteria’s success in causing this life-threatening condition. Using genomic sequencing, they have found how certain strains of bacteria that usually live harmlessly on the skin can evade control measures by colonizing babies’ guts. This will provide new ways to control this threat to babies’ health.
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 Metal-loving microbes could replace chemical processing of rare earths
(via sciencedaily.com) Original source Scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
Published Scientists identify evolutionary gateway helping pneumonia bacteria become resistant to antibiotics
(via sciencedaily.com) Original source An evolutionary gateway which helps pneumonia cells become resistant to antibiotics has been discovered.
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.
