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 Invertebrate biodiversity is improving in England's rivers, long-term trends show
(via sciencedaily.com) Original source Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Bird species changing faster than expected in protected areas
(via sciencedaily.com) Original source A recent study has found that bird communities inside and outside protected areas are beginning to resemble each other as a result of climate change. In both areas, southern species increase in abundance, while northern species decrease.
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 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 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 Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
Published A prehistoric cosmic airburst preceded the advent of agriculture in the Levant
(via sciencedaily.com) Original source Agriculture in Syria started with a bang 12,800 years ago as a fragmented comet slammed into the Earth’s atmosphere. The explosion and subsequent environmental changes forced hunter-gatherers in the prehistoric settlement of Abu Hureyra to adopt agricultural practices to boost their chances for survival.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say
(via sciencedaily.com) Original source The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Large mound structures on Kuiper belt object Arrokoth may have common origin
(via sciencedaily.com) Original source A new study posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper Belt object Arrokoth are similar enough to suggest a common origin. The study suggests that these “building blocks” could guide further work on planetesimal formational models.
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 Viruses dynamic and changing after dry soils are watered
(via sciencedaily.com) Original source Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research.
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.
