Published Cognitive strategies for augmenting the body with a wearable, robotic arm
(via sciencedaily.com)
Original source 
Scientists show that breathing may be used to control a wearable extra robotic arm in healthy individuals, without hindering control of other parts of the body.
Published Wildfires also impact aquatic ecosystems
(via sciencedaily.com)
Original source 
Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for fisheries and water quality.
Published Can AI be too good to use?
(via sciencedaily.com)
Original source 
Much of the discussion around implementing artificial intelligence systems focuses on whether an AI application is 'trustworthy': Does it produce useful, reliable results, free of bias, while ensuring data privacy? But a new article poses a different question: What if an AI is just too good?
Published Artificial intelligence systems excel at imitation, but not innovation
(via sciencedaily.com)
Original source 
Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation, researchers have found.
Published Underwater architects: The 'burrowing effect' of foraminifera on marine environments
(via sciencedaily.com)
Original source 
Impact of single-cell organisms on sediment oxygen levels and bacterial diversity measured for the first time.
Published Have researchers found the missing link that explains the mysterious phenomenon known as fairy circles?
(via sciencedaily.com)
Original source 
Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. New research suggests that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.
Published Immersive VR goggles for mice unlock new potential for brain science
(via sciencedaily.com)
Original source 
New miniature virtual reality (VR) goggles provide more immersive experiences for mice living in laboratory settings. By more faithfully simulating natural environments, the researchers can more accurately and precisely study the neural circuitry that underlies behavior. Compared to current state-of-the-art systems, which simply surround mice with computer or projection screens, the new goggles provide a leap in advancement.
Published World's first logical quantum processor
(via sciencedaily.com)
Original source 
A team has realized a key milestone in the quest for stable, scalable quantum computing. For the first time, the team has created a programmable, logical quantum processor, capable of encoding up to 48 logical qubits, and executing hundreds of logical gate operations. Their system is the first demonstration of large-scale algorithm execution on an error-corrected quantum computer, heralding the advent of early fault-tolerant, or reliably uninterrupted, quantum computation.
Published Coral reefs in peril from record-breaking ocean heat
(via sciencedaily.com)
Original source 
Record breaking marine heatwaves will cause devastating mass coral bleaching worldwide in the next few years, according to a coral reef scientist.
Published ChatGPT often won't defend its answers -- even when it is right
(via sciencedaily.com)
Original source 
ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong.
Published Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat
(via sciencedaily.com)
Original source 
Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.
Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com)
Original source 
The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published Artificial intelligence makes gripping more intuitive
(via sciencedaily.com)
Original source 
Artificial hands can be operated via app or with sensors placed in the muscles of the forearm. New research shows: a better understanding of muscle activity patterns in the forearm supports a more intuitive and natural control of artificial limbs. This requires a network of 128 sensors and artificial intelligence based techniques.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com)
Original source 
A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Published Tiny electromagnets made of ultra-thin carbon
(via sciencedaily.com)
Original source 
Graphene, that is extremely thin carbon, is considered a true miracle material. An international research team has now added another facet to its diverse properties with new experiments: Experts fired short terahertz pulses at micrometer-sized discs of graphene, which briefly turned these minuscule objects into surprisingly strong magnets. This discovery may prove useful for developing future magnetic switches and storage devices.
Published Crocodile family tree mapped: New light shed on croc evolution
(via sciencedaily.com)
Original source 
Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
Published Decoding flavonoid metabolism: A closer look at plant-based diets
(via sciencedaily.com)
Original source 
An international team of researchers has elucidated the process by which the major flavonoids naringenin, apigenin, and genistein are metabolized in the body. These findings are fundamental in elucidating the correlation between the metabolism of flavonoids in the body and their potential health benefits.
Published To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem'
(via sciencedaily.com)
Original source 
Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed life-and-death scenario inspired by the so-called 'trolley problem.'
Published Scientists build tiny biological robots from human cells
(via sciencedaily.com)
Original source 
Scientists have created tiny moving biological robots from human tracheal cells that can encourage the growth of neurons across artificial 'wounds' in the lab.
