Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Making AI smarter with an artificial, multisensory integrated neuron
(via sciencedaily.com) Original source The feel of a cat's fur can reveal some information, but seeing the feline provides critical details: is it a housecat or a lion? While the sound of fire crackling may be ambiguous, its scent confirms the burning wood. Our senses synergize to give a comprehensive understanding, particularly when individual signals are subtle. The collective sum of biological inputs can be greater than their individual contributions. Robots tend to follow more straightforward addition, but researchers have now harnessed the biological concept for application in artificial intelligence (AI) to develop the first artificial, multisensory integrated neuron.
Published Evolution wired human brains to act like supercomputers
(via sciencedaily.com) Scientists have confirmed that human brains are naturally wired to perform advanced calculations, much like a high-powered computer, to make sense of the world through a process known as Bayesian inference.
Published Battery-free robots use origami to change shape in mid-air
(via sciencedaily.com) Researchers have developed small robotic devices that can change how they move through the air by 'snapping' into a folded position during their descent. Each device has an onboard battery-free actuator, a solar power-harvesting circuit and controller to trigger these shape changes in mid-air.
Published Largest historic fire death toll belongs to aftermath of 1923 Japan Earthquake
(via sciencedaily.com) Original source Fires that raged in the days following the 1 September 1923 magnitude 7.9 Kant earthquake killed roughly 90% of the 105,000 people who perished in and around Tokyo, making it one of the deadliest natural disasters in history -- comparable to the number of people killed in the World War II atomic bombing of Hiroshima. The story of the conflagration, not well-known outside of Japan, holds important lessons for earthquake scientists, emergency response teams and city planners, according to a new article.
Published 'Brainless' robot can navigate complex obstacles
(via sciencedaily.com) Researchers who created a soft robot that could navigate simple mazes without human or computer direction have now built on that work, creating a 'brainless' soft robot that can navigate more complex and dynamic environments.
Published What do neurons, fireflies and dancing the Nutbush have in common?
(via sciencedaily.com) Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.
Published New research highlights opportunities to protect carbon and communities from forest fires
(via sciencedaily.com) Original source As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.
Published Breathe! The shape-shifting ball that supports mental health
(via sciencedaily.com) A soft ball designed to support mental health by 'personifying' breath has been invented by a computer science student.
Published Tiny, shape-shifting robot can squish itself into tight spaces
(via sciencedaily.com) Imagine a robot that can wedge itself through the cracks in rubble to search for survivors trapped in the wreckage of a collapsed building. Engineers are working toward to that goal with CLARI, short for Compliant Legged Articulated Robotic Insect.
Published Paving the way for advanced quantum sensors
(via sciencedaily.com) Quantum physics has allowed for the creation of sensors far surpassing the precision of classical devices. Now, several new studies show that the precision of these quantum sensors can be significantly improved using entanglement produced by finite-range interactions. Researchers were able to demonstrate this enhancement using entangled ion-chains with up to 51 particles.
Published Wildfire, soil emissions increasing air pollution in remote forests
(via sciencedaily.com) Original source Nitrogen dioxide levels in remote forest areas are increasing, and wildfire and soil emissions are likely the reasons why, finds a new study.
Published AI helps robots manipulate objects with their whole bodies
(via sciencedaily.com) A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.
Published Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses
(via sciencedaily.com) Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Published New dual-arm robot achieves bimanual tasks by learning from simulation
(via sciencedaily.com) An innovative bimanual robot displays tactile sensitivity close to human-level dexterity using AI to inform its actions.
Published Do measurements produce the reality they show us?
(via sciencedaily.com) The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.
Published How artificial intelligence gave a paralyzed woman her voice back
(via sciencedaily.com) Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
Published Despite fears to the contrary, Canadian wildfire smoke exposure was not much worse than a bad pollen day in New York City
(via sciencedaily.com) Original source New Yorkers can apparently breathe a sigh of relief, at least for now. Their exposure to the smoke in June 2023 from Canadian wildfires led to only a slightly higher bump in visits to New York City hospital emergency departments for breathing problems or asthma attacks than what is seen on days when pollen counts are high. However, authors of a new study say other possible health effects, such as possible heart attacks and stroke, still need to be investigated.
Published REBURN: A new tool to model wildfires in the Pacific Northwest and beyond
(via sciencedaily.com) Original source Researchers have developed a new tool, REBURN, that can simulate large forest landscapes and wildfire dynamics over decades or centuries under different wildfire management strategies. The model can simulate the consequences of extinguishing all wildfires regardless of size, which was done for much of the 20th century and has contributed to a rise in large and severe wildfires, or of allowing certain fires to return to uninhabited areas to help create a more 'patchwork' forest structure that can help lessen fire severity. REBURN can also simulate conditions where more benign forest landscape dynamics have fully recovered in an area.
Published Without aggressive climate action, U.S. property values will take a hit from escalating wildfire risk and tree mortality, study finds
(via sciencedaily.com) Original source Research attempts to quantify the value of U.S. property at risk in forested areas exposed to increased ecological disturbance associated with climate change, such as wildfire and tree mortality. Property exposed to such climate risks, especially in California, is project to climb substantially if emission-reduction measures are not taken.
