Published Old immune systems revitalized in mouse study, improving vaccine response
(via sciencedaily.com) Original source Those with aging immune systems struggle to fight off novel viruses and respond weakly to vaccination. Researchers were able to revitalize the immune system in mice.
Published The behavior of ant queens is shaped by their social environment
(via sciencedaily.com) Original source The queens in colonies of social insects, such as ants, bees, and wasps, are considered the veritable embodiment of specialization in the animal kingdom. The common perception is that the queen's only task is to lay eggs -- and that this attribute is an inherent trait, not influenced by external factors. In contrast, recent research has demonstrated that in certain ant colonies the social environment can play a crucial role in shaping the behavioral specialization of the queens.
Published New testing approach improves detection of rare but emerging Powassan virus spread by deer ticks
(via sciencedaily.com) Original source Researchers have come up with a new, more accurate method for detecting in ticks the emerging Powassan virus, which can cause life-threatening neuroinvasive disease, including encephalitis and meningitis.
Published Researchers show that introduced tardigrade proteins can slow metabolism in human cells
(via sciencedaily.com) Original source Tardigrade proteins are potential candidates in technologies centered on slowing the aging process and in long-term storage of human cells.
Published Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge
(via sciencedaily.com) Original source A study is the first to evaluate substrate recolonization by sponges in the U.S. Virgin Islands after two catastrophic storms using genetic analyses to understand how much clonality verses sexual recruitment occurs on coral reefs post-storms. Results show that populations of clonal marine species with low pelagic dispersion, such as A. cauliformis, may benefit from increased frequency and magnitude of hurricanes to maintain genetic diversity and combat inbreeding, enhancing the resilience of Caribbean sponge communities to extreme storm events.
Published Silicon spikes take out 96% of virus particles
(via sciencedaily.com) Original source An international research team has designed and manufactured a virus-killing surface that could help control disease spread in hospitals, labs and other high-risk environments.
Published Discovery of amino acid unveils how light makes plants open
(via sciencedaily.com) Original source Scientists have uncovered a unique mechanism that regulates the opening of stomata in plants. Phosphorylation of the amino acid Thr881 on the plasma membrane proton pump plays a key role in this process. The study paves the way for the targeted manipulation of plant physiology, with potential applications in agriculture and environmental sustainability.
Published New roadmap to prevent pandemics centers on protecting biodiversity
(via sciencedaily.com) Original source An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Research lights up process for turning CO2 into sustainable fuel
(via sciencedaily.com) Original source Researchers have successfully transformed CO2 into methanol by shining sunlight on single atoms of copper deposited on a light-activated material, a discovery that paves the way for creating new green fuels.
Published GPT-4 for identifying cell types in single cells matches and sometimes outperforms expert methods
(via sciencedaily.com) Original source GPT-4 can accurately interpret types of cells important for the analysis of single-cell RNA sequencing -- a sequencing process fundamental to interpreting cell types -- with high consistency compared to that of time-consuming manual annotation by human experts of gene information.
Published Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests
(via sciencedaily.com) Original source When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.
Published Pairing crypto mining with green hydrogen offers clean energy boost
(via sciencedaily.com) Original source Pairing cryptocurrency mining -- notable for its outsize consumption of carbon-based fuel -- with green hydrogen could provide the foundation for wider deployment of renewable energy, such as solar and wind power, according to a new study.
Published Bees use antennae to decode hive mates' dances in the dark
(via sciencedaily.com) Original source Scientists have discovered how honeybees can decipher dances by their hive mates that relay directions to food.
Published 'Winners and losers' as global warming forces plants uphill
(via sciencedaily.com) Original source Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.
Published Breakthrough antibiotic shows promise against obstinate mycobacterial infections
(via sciencedaily.com) Original source A team of scientists has developed a novel antibiotic named COE-PNH2 that is capable of combating hard-to-treat mycobacterial lung infections. Such infections, which are notorious for resisting conventional treatment, pose a serious health threat, especially to the elderly and those with underlying conditions.
Published Humans pass more viruses to other animals than we catch from them
(via sciencedaily.com) Original source Humans pass on more viruses to domestic and wild animals than we catch from them, according to a major new analysis of viral genomes.
Published Caller ID of the sea: Tagging whale communication and behavior
(via sciencedaily.com) Original source Biologists use a novel method of simultaneous acoustic tagging to gain insights into the link between whale communication and behavior
Published Researchers discover evolutionary 'tipping point' in fungi
(via sciencedaily.com) Original source Scientists have found a 'tipping point' in the evolution of fungi that throttles their growth and sculpts their shapes. The findings demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.
Published Researchers take major step toward developing next-generation solar cells
(via sciencedaily.com) Original source Engineers have discovered a new way to manufacture solar cells using perovskite semiconductors. It could lead to lower-cost, more efficient systems for powering homes, cars, boats and drones.
