A new study shows for the first time that wildfires burning in West Coast states can strengthen storms in downwind states. Heat and tiny airborne particles produced by western wildfires distantly intensify severe storms, in some cases bringing baseball-sized hail, heavier rain and flash flooding to states like Colorado, Wyoming, Nebraska, Kansas, Oklahoma, and the Dakotas.
Published only days before the Commission for the Conservation of Antarctic Marine Living Resources' annual meeting, this evidence-based commentary notes that current levels of fishing, combined with climate change, are taking a concerning toll on this diverse ecosystem of global importance.
At population level, passive monitoring of walking activity using smartphones offers a pathway toward national screening for health and mortality risk, researchers conclude.
New research shows that black wolves are more likely to survive outbreaks of canine distemper virus (CDV). Yellowstone Natural Park wolves prefer to mate with those of the opposite color in areas where CDV outbreaks happen to improve the fitness of their offspring. CDV outbreaks may explain why black wolves become more common further south in North America.
A new study shows for the first time that carefully placed no-fishing zones can help to restore tunas and other large, iconic fish species.
Spectrometers are widely used throughout industry and research to detect and analyze light. Spectrometers measure the spectrum of light -- its strength at different wavelengths, like the colors in a rainbow -- and are an essential tool for identifying and analyzing specimens and materials. Integrated on-chip spectrometers would be of great benefit to a variety of technologies, including quality...
A new computing architecture enables advanced machine-learning computations to be performed on a low-power, memory-constrained edge device. The technique may enable self-driving cars to make decisions in real-time while only using a fraction of the energy that is currently demanded by their power-hungry on-board computers.
Scientists have developed a new way of looking at sex-biased diseases that is rooted in evolutionary biology.
The quality of food sockeye salmon eat along their migration routes is more important to their growth and condition than quantity, a new study has found, highlighting concerns about the effects of climate change on ocean conditions and salmon.
Research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical treatments.
Scientists have identified a long-sought gene-encoded protein that enables the brain to communicate a broad range of signals across gaps between neurons, known as synapses.
Researchers have provided a measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing complex quantum materials. The identification of both repulsive (long-range)and attractive (short range) interactions, and the underlying mechanisms, is an important step to unraveling the rich physics of complex quantum materials...
Researchers have engineered a quantum box for polaritons in a 2D material, achieving large polariton densities and a partially 'coherent' quantum state. New insights from the novel technique could allow researchers to access striking 'collective' quantum phenomena in this material family, and enable ultra-energy efficient and high-performance future technologies. Laying a 'small' 2D material on...
Eating a handful of almonds a day significantly increases the production of butyrate, a short-chain fatty acid that promotes gut health, according to a recent study.
Researchers used artificial nests to test two methods for reducing the nest predation of vulnerable and endangered ground-nesting birds. The study showed that red foxes can be more easily deceived into not eating bird eggs than raccoon dogs. The methods could be used alongside hunting and offer an alternative, non-lethal solution for creating protection for vulnerable prey.
For proper operation, drones usually use accelerometers to determine the direction of gravity. Scientists have now shown that drones can estimate the direction of gravity by combining visual detection of movement with a model of how they move. These results may explain how flying insects determine the direction of gravity and are a major step toward the creation of tiny autonomous drones.
The research framework developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those...
The skin is a large, complex organ, and it serves as the body's primary interface with the environment, playing key roles in sensory, thermoregulatory, barrier, and immunological functioning. As floods, wildfires, and extreme heat events increase in frequency and severity, they pose a significant threat to global dermatological health, as many skin diseases are climate sensitive.
In response to a high-competition environment, Trinidadian killifish evolve larger brains, increasing their fitness and survival rates, according to a new study.
Ahead of the global meeting of the Conference of the Parties in Montréal, Canada, which decides new targets for nature, a new study outlines an urgent need for larger numbers and better-supported protected area staff to ensure the health of life on Earth. Scientists argue that there are not enough rangers and other staff to manage even the current protected areas around the world. The authors...
The iconic, glacier-carved features of Yosemite Valley appeared sometime during the past 50 million years, when Sierra Nevada granite was first exposed, but geologists have not been able to establish exactly when the valley as we know it today appeared. Using a relatively new rock analysis technique park geologists have narrowed it down to within the past 10 million years, and probably within the...
Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.
A new study has revealed that chimpanzees share a human tendency to unintentionally synchronize their steps when walking alongside one another.
High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behavior. Now, a team has gained new insights into the local environment of a so-called high-entropy Cantor alloy made of chromium, manganese, iron, cobalt and nickel, and has thus also been able to...
