Two epicenters led to Japan's violent Noto earthquake on New Year's Day      (via sciencedaily.com)     Original source 

The 7.5- magnitude earthquake beneath Japan's Noto Peninsula on Jan. 1, 2024, occurred when a 'dual-initiation mechanism' applied enough energy from two different locations to break through a fault barrier -- an area that locks two sides of a fault in place and absorbs the energy of fault movement, slowing it down or stopping it altogether.

Scientists call for an update in environmental decision making that takes human rights into account      (via sciencedaily.com)     Original source 

Researchers argue that to protect human wellbeing global decisions with the potential to impact the environment must be guided by our understanding of the inseparable connection between humans and nature. The article's authors are aiming to support fair and inclusive decision-making for a healthy ocean for people and planet.

Colorful traits in primates ease tensions between groups      (via sciencedaily.com)     Original source 

Primate ornamentation plays a crucial role in communication not only within social groups but also between them, according to a new study. The research reveals that the males of species with overlapping home ranges often display vibrant colors or elaborate features, traits that may help reduce intergroup aggression by enabling quick assessments of potential rivals.

Fisheries research overestimates fish stocks      (via sciencedaily.com)     Original source 

The state of fish stocks in the world's ocean is worse than previously thought. While overfishing has long been blamed on fisheries policies that set catch limits higher than scientific recommendations, a new study reveals that even these scientific recommendations were often too optimistic. The result? Far more global fish stocks are overfished or have collapsed than we thought.

Mitochondria are flinging their DNA into our brain cells      (via sciencedaily.com)     Original source 

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm.

Creature the size of a dust grain found hiding in California's Mono Lake      (via sciencedaily.com)     Original source 

Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.

What works: Groundbreaking evaluation of climate policy measures over two decades      (via sciencedaily.com)     Original source 

Researchers have unveiled the first comprehensive global evaluation of 1,500 climate policy measures from 41 countries across six continents. The study provides a detailed impact analysis of the wide range of climate policy measures implemented over the last two decades. The findings reveal a sobering reality: many policy measures have failed to achieve the necessary scale of emissions reductions. Only 63 cases of successful climate policies, each leading to average emission reductions of 19 percent, were identified. The key characteristic of these successful cases is the inclusion of tax and price incentives in well-designed policy mixes.

Fighting coastal erosion with electricity      (via sciencedaily.com)     Original source 

New research has systematically demonstrated that a mild zap of electricity can strengthen a marine coastline for generations -- greatly reducing the threat of erosion in the face of climate change and rising sea levels. The new process forms natural cement between grains of sand, transforming it into solid, immoveable rock. Mollusks use a similar process to turn naturally occurring minerals into shells.

Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.

Will EEG be able to read your dreams? The future of the brain activity measure as it marks 100 years      (via sciencedaily.com)     Original source 

One hundred years after the human brain's electrical activity was first recorded, experts are celebrating the legacy of its discovery and sharing their predictions and priorities for its future. A survey saw respondents -- with 6,685 years of collective experience -- presented with possible future developments for EEG, ranging from those deemed 'critical to progress' to the 'highly improbable,' and asked to estimate how long it might be before they were achieved.

Pollution drives families to relocate -- but only the rich can afford to live in healthier areas      (via sciencedaily.com)     Original source 

Pollution levels factor in households' decision to relocate within the United States, but only richer households can afford areas with improved air quality, a new study finds. Researchers analyse detailed origin and destination information of relocating households, rather than just aggregate migration flows, and uncover a direct link between a household's income and their new chosen county of residence. They find inequalities exist when it comes to who is exposed to the worst areas of pollution -- with poorer families hit hardest. Richer households opt to move into cleaner, healthier areas that tend to be more expensive. However poorer families are priced out of these counties and are the ones who move into areas with higher levels of toxic releases.
