Published As the worm turns: New twists in behavioral association theories
(via sciencedaily.com) Physicists have developed a dynamical model of animal behavior that may explain some mysteries surrounding associative learning going back to Pavlov's dogs.
Published Microplastics limit energy production in tiny freshwater species
(via sciencedaily.com) Microplastic pollution reduces energy production in a microscopic creature found in freshwater worldwide, new research shows.
Published Harnessing power of immune system may lessen reliance on antibiotics for infections like TB
(via sciencedaily.com) Researchers have found that the body's process of removing old and damaged cell parts, is also an essential part of tackling infections that take hold within our cells, like TB. If this natural process can be harnessed with new treatments, it could present an alternative to, or improve use of antibiotics, especially where bacteria have become resistant to existing drugs.
Published Newly discovered cell in fruit flies is essential for touch sensation
(via sciencedaily.com) Researchers have uncovered a key role for a new type of cell in touch detection in the skin of the fruit fly.
Published Researchers discover a way to fight the aging process and cancer development
(via sciencedaily.com) Damage in the human genome can be repaired. But this works better in germ cells, sperm and eggs, than in normal body cells. Responsible for this is the DREAM protein complex, which prevents the activation of all available repair mechanisms. A research team has now shown that normal body cells can also be repaired better once this complex has been deactivated. In the long run, the scientists hope to develop better therapies to prevent cancer and aging-associated diseases.
Published Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
Published What really matters in multi-story building design?
(via sciencedaily.com) The impact of multi-story building design considerations on embodied carbon emissions, cost, and operational energy has been revealed.
Published At least 80% of the world's most important sites for biodiversity on land currently contain human developments
(via sciencedaily.com) At least 80% of sites identified as being internationally important for biodiversity on land currently contain infrastructure -- of which more than 75% contain roads. In the future, more sites that are important for biodiversity could contain powerplants, mines and oil and gas infrastructure.
Published Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability
(via sciencedaily.com) Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.
Published Artificial intelligence discovers secret equation for 'weighing' galaxy clusters
(via sciencedaily.com) Astrophysicists have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had. The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists have reported.
Published New in-home AI tool monitors the health of elderly residents
(via sciencedaily.com) Engineers are harnessing artificial intelligence (AI) and wireless technology to unobtrusively monitor elderly people in their living spaces and provide early detection of emerging health problems.
Published New wood-based technology removes 80% of dye pollutants in wastewater
(via sciencedaily.com) Researchers have developed a new method that can easily purify contaminated water using a cellulose-based material. This discovery could have implications for countries with poor water treatment technologies and combat the widespread problem of toxic dye discharge from the textile industry.
Published Pressure-based control enables tunable singlet fission materials for efficient photoconversion
(via sciencedaily.com) Applying hydrostatic pressure as an external stimulus, researchers demonstrate a new way to regulate singlet fission (SF), a process in which two electrons are generated from a single photon, in chromophores, opening doors to the design of SF-based materials with enhanced (photo)energy conversion. Their method overrides the strict requirements that limit the molecular design of such materials by realizing an alternative control strategy.
Published AI finds the first stars were not alone
(via sciencedaily.com) Machine learning and state-of-the-art supernova nucleosynthesis has helped researchers find that the majority of observed second-generation stars in the universe were enriched by multiple supernovae.
Published Without this, plants cannot respond to temperature
(via sciencedaily.com) Scientists have significantly advanced the race to control plant responses to temperature on a rapidly warming planet. Key to this breakthrough is miRNA, a molecule nearly 200,000 times smaller than the width of a human hair.
Published Scientists warn of rise in potentially fatal bacterial infection due to global warming
(via sciencedaily.com) Continued warming of the climate would see a rise in the number and spread of potentially fatal infections caused by bacteria found along parts of the coast of the United States. Vibrio vulnificus bacteria grow in warm shallow coastal waters and can infect a cut or insect bite during contact with seawater. The researchers predict that by 2041--2060 infections may spread to encompass major population centers around New York. Combined with a growing and increasingly elderly population, who are more susceptible to infection, annual case numbers could double.
Published Genome of a drought-tolerant plant: Many genes are involved in 'resurrection'
(via sciencedaily.com) Some plants can survive months without water, only to turn green again after a brief downpour. A recent study shows that this is not due to a 'miracle gene.' Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
Published Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets
(via sciencedaily.com) Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.
Published Paper written using ChatGPT demonstrates opportunities and challenges of AI in academia
(via sciencedaily.com) In an innovative new study, researchers used a series of prompts and questions to encourage ChatGPT to produce the type of content commonly seen in academic publications. Researchers say in their paper's discussion section -- which was written without the software's influence -- that it demonstrates the new levels of sophistication which AI now offers and also the opportunities and challenges it poses for the academic community.
Published Drought, heat waves worsen West Coast air pollution inequality
(via sciencedaily.com) A new study found drought and heat waves could make air pollution worse for communities that already have a high pollution burden in California, and deepen pollution inequalities along racial and ethnic lines. The study also found financial penalties for power plants can significantly reduce people's pollution exposure, except during severe heat waves.
