Graphene discovery could help generate hydrogen cheaply and sustainably      (via sciencedaily.com) 

Researchers have finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory.

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.

Mapping methane emissions from rivers around globe reveals surprising sources      (via sciencedaily.com)     Original source 

A new study finds rivers and streams at higher latitudes contributing as much methane, a potent greenhouse gas, to the atmosphere as warmer waters in the tropics. The surrounding habitat, not temperature, is the important driver of methane emissions. The findings could improve methane estimates and models of climate change, and point to land-management changes and restoration opportunities that can reduce the amount of methane escaping into the atmosphere.

This fish doesn't just see with its eyes -- it also sees with its skin      (via sciencedaily.com)     Original source 

Without a mirror, it can be hard to tell if you're blushing, or have spinach in your teeth. But one color-changing fish has evolved a clever way to keep watch on the parts of itself that lie outside its field of view -- by sensing light with its skin.

New test chamber created to find better ways to keep people cool      (via sciencedaily.com)     Original source 

A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures. Researchers created the 60 square-foot chamber to test passive systems that use wind towers along with water evaporation instead of electricity to cool spaces.

'Coastal squeeze:' Massive loss of U.S. coastline tidal flats over 31 years      (via sciencedaily.com)     Original source 

The entire contiguous U.S. has experienced massive urban expansions and the Atlantic Coast shows outstandingly high rates. Urban expansion has substantially squeezed the space of tidal flats and affected surrounding environments. In new urban areas, tidal flats have undergone considerable degeneration with more significant patterns as they get closer to new urban locations. Tidal flats protect against the ocean's destructive powers such as hurricanes. Without some inland spaces to move around, they will likely disappear, which will have dire consequences for beachfront communities.

Thinning ice sheets may drive sharp rise in subglacial waters      (via sciencedaily.com)     Original source 

A new study shows that water underneath glaciers may surge due to thinning ice sheets -- a dangerous feedback cycle that could increase glacial melt, sea level rise, and biological disturbances.

Climate win-win: Study quantifies benefits of enhanced weathering      (via sciencedaily.com)     Original source 

Applying ground-up silicate rock to Midwestern farm fields can capture significant amounts of carbon dioxide and prevent it from accumulating in the atmosphere, according to a new study that successfully quantified those climate benefits for the first time.

US can cut building emissions by up to 91%, saving $100 billion per year in energy-related costs, modeling study shows      (via sciencedaily.com)     Original source 

The US has committed to reaching net-zero emissions by 2050. To accomplish this goal, large cuts in emissions are necessary, especially in high-emission sectors like the building industry. Researchers use a computational model to analyze several scenarios of future building energy use in the US. They find that by tackling emissions on multiple fronts and placing focus on 'demand-side measures' that affect how power is drawn from the grid, such as technologies like electric heat pumps and smart thermostats, the US can achieve its climate goals, decrease building emissions by 91% from their 2005 peak, and save over $100 billion each year on energy costs.

Increasing legumes and reducing red meat is safe for bone health and protein intake      (via sciencedaily.com)     Original source 

A study has demonstrated that the partial substitution of red and processed meat with pea- and faba bean -- based food products ensured sufficient intake of amino acids in the diet and did not negatively affect bone metabolism.

Pollutants are important to biodiversity's role in spread of wildlife diseases      (via sciencedaily.com) 

Conventional wisdom among ecologists holds that the more species there are inhabiting an ecosystem, the less vulnerable any one species will be to a threat like a parasite. A new study of tadpoles illustrates how overlapping biological and environmental factors can complicate how we value protecting diverse animal communities. The researchers found that environmental pollutants like road salt influence whether increased biodiversity helps or hinders disease outbreaks in wildlife, which can complicate how we value protecting diverse animal communities.

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.

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.
