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 New method to measure entropy production on the nanoscale
(via sciencedaily.com)
Original source 
Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser excited materials.
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 Micro-Lisa! Making a mark with novel nano-scale laser writing
(via sciencedaily.com)
Original source 
High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.
Published Tiniest 'starquake' ever detected
(via sciencedaily.com)
Original source 
An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Mathematical innovations enable advances in seismic activity detection
(via sciencedaily.com)
Original source 
Scientists successfully addressed mathematical challenges in conventional Spectral Matrix analysis, used to analyze three-component seismic signals, by introducing time-delay components. The new technique enables the characterization of various polarized waves and the detection of seismic events that have previously gone unnoticed by conventional methods. These findings pave the way for improving a variety of applications, including earthquake detection.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole
(via sciencedaily.com)
Original source 
An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
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 New maps help decision-makers factor albedo into tree-planting decisions
(via sciencedaily.com)
Original source 
A new study provides a global analysis of where restoration of tree cover is most effective at cooling the global climate system, considering not just the cooling from carbon storage but also the warming from decreased albedo. The researchers provide a tool practitioners and land managers can use to determine just how much of a problem albedo is for any reforestation or afforestation project on the globe.
Published Climate change will see Australia's soil emit CO2 and add to global warming
(via sciencedaily.com)
Original source 
New research has shown the warming climate will turn Australia's soil into a net emitter of carbon dioxide (CO2), unless action is taken. Soil helps to keep the planet cool by absorbing carbon, however as the climate gets warmer its ability to retain carbon decreases -- and in some instances can start to release some carbon back into the air. A global research team has predicted the changes in the amount of carbon in Australia's soil between now and the year 2100.
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 Crackdown on illicit drugs detects rise in 'designer' drug substitutes
(via sciencedaily.com)
Original source 
As authorities crack down on illicit drugs, experts have issued an alert on the use of the synthetic stimulant pentylone, as new research finds a 75% increase in detections across Australia.
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 Engineering household robots to have a little common sense
(via sciencedaily.com)
Original source 
Engineers aim to give robots a bit of common sense when faced with situations that push them off their trained path, so they can self-correct after missteps and carry on with their chores. The team's method connects robot motion data with the common sense knowledge of large language models, or LLMs.
Published Novel electrochemical sensor detects dangerous bacteria
(via sciencedaily.com)
Original source 
Researchers have developed a novel sensor for the detection of bacteria. It is based on a chip with an innovative surface coating. This ensures that only very specific microorganisms adhere to the sensor -- such as certain pathogens. The larger the number of organisms, the stronger the electric signal generated by the chip. In this way, the sensor is able not only to detect dangerous bacteria with a high level of sensitivity but also to determine their concentration.
Published Research identifies characteristics of cities that would support young people's mental health
(via sciencedaily.com)
Original source 
As cities around the world continue to draw young people for work, education, and social opportunities, a new study identifies characteristics that would support young urban dwellers' mental health. The findings, based on survey responses from a global panel that included adolescents and young adults, provide a set of priorities that city planners can adopt to build urban environments that are safe, equitable, and inclusive.
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
