Trees in wetter forests more sensitive to drought than trees in drier regions – a finding with policy implications

A recent study analyzing tree ring measurements from 122 species found that trees in wetter forests are more vulnerable to drought than those in drier regions. This suggests that land management policies focused solely on drier regions overestimate the resilience of forests in wetter areas.

Mortality burden of air pollution from coal-burning power plants has been underestimated

A new study estimates that over 460,000 US deaths were attributed to air pollution from coal-burning power plants between 1999 and 2020. The findings highlight the increased mortality risks from coal electricity generation, while also showing that emission-reduction policies have been effective in preventing excess death.

Dolomite crystals require cycles of saturation conditions to grow

Researchers have discovered that dolomite crystal growth requires cycling of saturation conditions, resolving the 'dolomite problem' that has puzzled scientists for nearly two centuries. This process can speed up dolomite growth by up to 10 million times, which may be crucial for producing large amounts of dolomite on Earth's surface.

Introducing: Ceramic- and glass-based passive radiative cooling materials resistance to harsh environments

Researchers have developed microporous glass and ceramic coatings that exhibit passive daytime radiative cooling and high solar reflectance, with the potential to reduce air conditioning demands and mitigate climate change. The materials maintain their properties even under harsh environments, making them suitable for large-scale outdo...

A safer alternative to CRISPR-Cas approaches?: Retroelement-based genome editing tools

Researchers propose retroelement-based gene editing as a safer alternative to CRISPR-Cas systems due to reduced risk of DNA double strand breaks and unwanted chromosomal modifications. This approach leverages endogenous mobile genetic elements, which can be programmed for targeted genomic engineering without generating DSB.

A new “species” of legal subject: AI-led corporate entities, requiring interspecific legal frameworks

The American Association for the Advancement of Science suggests that AI-operated corporate entities should be recognized as a new 'species' in the legal system. This would involve developing interspecific legal frameworks to address rights and obligations, allowing AI systems to function autonomously without human oversight.

New, independent ages confirm antiquity of ancient human footprints at White Sands

Ancient human footprints discovered in White Sands National Park have been confirmed to be over 20,000 years old. Multiple independent age estimates from radiocarbon and optically simulated luminescence methods support the previous study's claims, showing humans inhabited southern North America during the Last Glacial Maximum.

What are the risks of radioactive wastewater release – the next of which is October 5th – from Fukushima Daiichi nuclear plant?

The planned releases of radioactive wastewater from Fukushima Daiichi will have negligible effects on the environment, according to a study published in Science. The predicted radiation doses from the discharges are smaller than exposure to natural radiation or medical x-rays, posing no real threat to local seafood consumers.
