How dust pollution from shrinking Great Salt Lake affects communities disproportionately      (via sciencedaily.com)     Original source 

Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.

Early-onset El Niño means warmer winters in East Asia, and vice versa      (via sciencedaily.com)     Original source 

Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.

Blue and great tits deploy surprisingly powerful memories to find food      (via sciencedaily.com)     Original source 

Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.

Study explores what motivates people to watch footage of disasters and extreme weather      (via sciencedaily.com)     Original source 

The release in July 2024 of the blockbuster film Twisters (centred around a social-media celebrity storm-chaser) demonstrates an ongoing public fascination in hazards and extreme weather. The arrival of camera and streaming technologies have made it easier to collect and share such footage in recent years, resulting in often dramatic footage being live-streamed on platforms such as YouTube, TikTok and Discord. Now, a new study has analyzed what might be motivating people to watch these streams -- in some instances for up to 12 hours at a time.

Spotted apex predator being pressured by spotted pack hunters -- and it's our fault      (via sciencedaily.com)     Original source 

Leopards, who are already in decline, can't keep up with hyenas when people are around. As we humans move into the their territories more and more, we are helping to disturb and unbalance ecosystems. This has been shown in a new study where researchers used camera traps to observe both large carnivore species.

Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive      (via sciencedaily.com)     Original source 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.

Dampening the 'seeds' of hurricanes      (via sciencedaily.com)     Original source 

Increased atmospheric moisture may alter critical weather patterns over Africa, making it more difficult for the predecessors of many Atlantic hurricanes to form, according to a new study.

The evidence is mounting: humans were responsible for the extinction of large mammals      (via sciencedaily.com)     Original source 

Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.

Antarctic ice shelves hold twice as much meltwater as previously thought      (via sciencedaily.com)     Original source 

Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.

New mathematical model sheds light on the absence of breastfeeding in male mammals      (via sciencedaily.com)     Original source 

Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.

Groundbreaking discovery: Zinc can make crop yields more climate-resilient      (via sciencedaily.com)     Original source 

Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.

To protect corals from summer heatwaves, we should help their microbial symbionts evolve heat tolerance in the lab      (via sciencedaily.com)     Original source 

Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused the bleaching event in the first place. Researchers discuss the potential of improving corals' chances by inducing the evolution of heat tolerance in their symbionts -- the mutualistic microbes that provide corals with nutrients in exchange for shelter and that are expelled during coral bleaching.

Common plastics could passively cool and heat buildings with the seasons      (via sciencedaily.com)     Original source 

By restricting radiant heat flows between buildings and their environment to specific wavelengths, coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve.

New twists on tornadoes: Earth scientist studies why U.S. has so many tornadoes      (via sciencedaily.com)     Original source 

Across the Midwest during the warmer months, studying the sky for signs of storms and tornadoes becomes one of the most popular pastimes. Working at the intersection of climate science and meteorology and using modeling, scientists are looking at the big picture of what causes severe storms and tornadoes -- and what dictates where they occur.

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems      (via sciencedaily.com)     Original source 

Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds      (via sciencedaily.com)     Original source 

We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
