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.

Human-wildlife overlap expected to increase across more than half of land on Earth by 2070      (via sciencedaily.com)     Original source 

Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.

New study reveals devastating power and colossal extent of a giant underwater avalanche off the Moroccan coast      (via sciencedaily.com)     Original source 

New research has revealed how an underwater avalanche grew more than 100 times in size causing a massive trail of destruction as it traveled 2000km across the Atlantic Ocean seafloor off the North West coast of Africa. Researchers provide an unprecedented insight into the scale, force and impact of one of nature's mysterious phenomena, underwater avalanches.

Pilot study uses recycled glass to grow plants for salsa ingredients      (via sciencedaily.com)     Original source 

Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.

Will climate change lead to the extinction of a newly discovered tarantula species?      (via sciencedaily.com)     Original source 

Biologists have discovered a new species of tarantula from the Madrean Sky Island biodiversity hotspot in southeastern Arizona. This remarkable new species is endemic to the Chiricahua Mountains and is predominately distributed in mid- to high-elevation forests, which are increasingly threatened due to climate change.

Scottish and Irish rocks confirmed as rare record of 'snowball Earth'      (via sciencedaily.com)     Original source 

The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.

A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth's history. These plagioclase-rich igneous rock formations, which can cover areas as large as 42,000 square kilometers and host titanium ore deposits, have puzzled scientists for decades due to conflicting theories about their origins.

Ecologists put an insect group on century-old map of biodiversity      (via sciencedaily.com)     Original source 

The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.
