It's not just humans: City life is stressful for coyotes, too      (via sciencedaily.com)     Original source 

Though cars are the biggest threat to coyotes taking up residence in U.S. cities, a new study suggests urban living poses a different kind of hazard to coyote health -- in the form of chronic stress. Researchers examined the concentration of the stress hormone cortisol in the hair of almost 100 coyotes living in the Chicago Metropolitan Area. Results showed that coyotes that lived in the most-developed areas had higher cortisol levels -- a proxy for chronic stress -- than animals living in suburban or natural areas.

Quantum physicists simulate super diffusion on a quantum computer      (via sciencedaily.com) 

Quantum physicists have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer. This is the first step in doing highly challenging quantum transport calculations on quantum hardware and, as the hardware improves over time, such work promises to shed new light in condensed matter physics and materials science.

Stabilizing precipitate growth at grain boundaries in alloys      (via sciencedaily.com) 

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure. Alloys, a combination of two or more types of metals, are used in many applications, like turbines for jet engines and light-weight alloys for automotive applications, because they have very good mechanical properties due to those embedded precipitates. The average precipitate size, however, tends to increase over time-in a process called coarsening-which results in a degradation of performance for microstructures with nanoscale precipitates.

To improve solar and other clean energy tech, look beyond hardware      (via sciencedaily.com) 

A new analysis reveals that soft technology, the processes to design and deploy a solar energy system, contributed far less to the total cost declines of solar installations than previously estimated. Their quantitative model shows that driving down solar energy costs in the future will likely require either improving soft technology or reducing system dependencies on soft technology features.

America's wealthiest 10% responsible for 40% of US greenhouse gas emissions      (via sciencedaily.com)     Original source 

A new study reveals that the wealthiest Americans, those whose income places them in the top 10% of earners, are responsible for 40% of the nation's total greenhouse gas emissions. The study links income, especially income derived from financial investments, to the emissions used in generating that income. The authors suggest that policymakers adopt taxes focused on shareholders and the carbon intensity of investment incomes in order to equitably meet the goal of keeping the global temperature to 1.5 C of warming.

Race-based variations in gut bacteria emerge by 3 months of age      (via sciencedaily.com)     Original source 

Early social and environmental exposures can have large and lasting effects on child development and adult health. One of the systems that is vulnerable to external influence is the gut microbiome. A new study highlights a critical development window during which racial differences in the gut microbiome emerge. The findings are based on analysis of data from 2,756 gut microbiome samples from 729 U.S. children between birth and 12 years of age.

New type of star gives clues to mysterious origin of magnetars      (via sciencedaily.com)     Original source 

Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they form. Now, using multiple telescopes around the world, researchers have uncovered a living star that is likely to become a magnetar. This finding marks the discovery of a new type of astronomical object -- massive magnetic helium stars -- and sheds light on the origin of magnetars.

New insights into fighting antimicrobial resistance      (via sciencedaily.com)     Original source 

Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut, according to a new study.

Heredity and environment account for people's love of nature      (via sciencedaily.com)     Original source 

Humans have a positive view of nature. But is this due to an approach we have learned while growing up, or is it something we are born with? The answer is 'Both', according to researchers.

Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima      (via sciencedaily.com)     Original source 

Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.

Greater excess mortality after hurricanes more recently and for most socially vulnerable in the U.S.      (via sciencedaily.com)     Original source 

Over recent decades, there was a large variation in cyclone-related excess deaths by hurricane, state, county, year, and social vulnerability for counties in the United States, with 83 percent of hurricane-related deaths occurring more recently and 94 percent in more socially vulnerable counties.

Medications for chronic diseases affect the body's ability to regulate body temperature, keep cool      (via sciencedaily.com)     Original source 

Medications to treat various chronic diseases may hinder the body's ability to lose heat and regulate its core temperature to optimal levels. The loss of effective thermoregulation has implications for elderly people receiving treatment for illnesses like cancer, cardiovascular, Parkinson's disease/dementia and diabetes, particularly during hot weather, according to a review by a team of scientists.

Scientists say deepening Arctic snowpack drives greenhouse gas emissions      (via sciencedaily.com)     Original source 

Human-caused climate change is shortening the snow cover period in the Arctic. But according to new research led by Earth system scientists, some parts of the Arctic are getting deeper snowpack than normal, and that deep snow is driving the thawing of long-frozen permafrost carbon reserves and leading to increased emissions of greenhouse gasses like carbon dioxide and methane.

Microplastic pollution: Plants could be the answer      (via sciencedaily.com)     Original source 

Could plants be the answer to the looming threat of microplastic pollution? Scientists found that if you add tannins (natural plant compounds that make your mouth pucker if you bite into an unripe fruit) to a layer of wood dust, you can create a filter that can trap virtually all microplastic particles present in water. While the experiment remains a lab set-up at this stage, the team is convinced that the solution can be scaled up easily and inexpensively.
