Published Can cities make room for woodpeckers?
(via sciencedaily.com) Original source Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.
Published English language pushes everyone -- even AI chatbots -- to improve by adding
(via sciencedaily.com) Original source A linguistic bias in the English language that leads us to 'improve' things by adding to them, rather than taking away, is so common that it is even ingrained in AI chatbots, a new study reveals.
Published Ants took over the world by following flowering plants out of prehistoric forests
(via sciencedaily.com) Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.
Published Scientists analyze sounds emitted by plants
(via sciencedaily.com) Researchers have recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.
Published How plants cope with the cold light of day -- and why it matters for future crops
(via sciencedaily.com) New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published Can AI predict how you'll vote in the next election?
(via sciencedaily.com) Artificial intelligence technologies like ChatGPT are seemingly doing everything these days: writing code, composing music, and even creating images so realistic you'll think they were taken by professional photographers. Add thinking and responding like a human to the conga line of capabilities. A recent study proves that artificial intelligence can respond to complex survey questions just like a real human.
Published New chip design to provide greatest precision in memory to date
(via sciencedaily.com) Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware become 'the bottleneck.' New collaborators might change that. They believe that they have developed a new type of chip with the best memory of any chip thus far for edge AI (AI in portable devices). To put it in context, right now, ChatGPT is running on a cloud. The new innovation, followed by some further development, could put the power of a mini version of ChatGPT in everyone's personal device. It could make such high-powered tech more affordable and accessible for all sorts of applications.
Published How whale shark rhodopsin evolved to see, in the deep blue sea
(via sciencedaily.com) A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Even Sonoran Desert plants aren't immune to climate change
(via sciencedaily.com) In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct
(via sciencedaily.com) New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Climate change threatens lemurs on Madagascar
(via sciencedaily.com) Even supposedly adaptable mammal species face increased risk of extinction.
Published What should we call evolution driven by genetic engineering? Genetic welding, says researcher
(via sciencedaily.com) With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.
Published First silicon integrated ECRAM for a practical AI accelerator
(via sciencedaily.com) The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.
Published Earth's first plants likely to have been branched
(via sciencedaily.com) A new discovery changes ideas about the origin of branching in plants.
Published Researchers find clue to help plants grow with low phosphorus levels
(via sciencedaily.com) Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Published AI 'brain' created from core materials for OLED TVs
(via sciencedaily.com) A research team develops semiconductor devices for high-performance AI operations by applying IGZO materials widely used in OLED displays.
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 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 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.
