how far can the wind can carry a plant's seeds? New model      (via sciencedaily.com)     Original source 

Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.

Slash-and-burn agriculture can increase forest biodiversity, researchers find      (via sciencedaily.com)     Original source 

The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.

Compact accelerator technology achieves major energy milestone      (via sciencedaily.com)     Original source 

Researchers have demonstrated a compact particle accelerator less than 20 meters long that produces an electron beam with an energy of 10 billion electron volts (10 GeV). There are only two other accelerators currently operating in the U.S. that can reach such high electron energies, but both are approximately 3 kilometers long. This type of accelerator is called a wakefield laser accelerator.

Deoxygenation levels similar to today's played a major role in marine extinctions during major past climate change event      (via sciencedaily.com)     Original source 

Scientists have made a surprising discovery that sheds new light on the role that oceanic deoxygenation (anoxia) played in one of the most devastating extinction events in Earth's history. Their finding has implications for current day ecosystems -- and serves as a warning that marine environments are likely more fragile than apparent. New research, published today in leading international journal Nature Geosciences, suggests that oceanic anoxia played an important role in ecosystem disruption and extinctions in marine environments during the Triassic--Jurassic mass extinction, a major extinction event that occurred around 200 million years ago.  Surprisingly however, the study shows that the global extent of euxinia (an extreme form of de-oxygenated conditions) was similar to the present day.

First experimental evidence of hopfions in crystals opens up new dimension for future technology      (via sciencedaily.com)     Original source 

Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. New findings open up new fields in experimental physics: identifying other crystals in which hopfions are stable, studying how hopfions interact with electric and spin currents, hopfion dynamics, and more.

Deep-sea mining and warming trigger stress in a midwater jellies      (via sciencedaily.com)     Original source 

The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.

Three-pronged approach discerns qualities of quantum spin liquids      (via sciencedaily.com)     Original source 

In 1973, physicist Phil Anderson hypothesized that the quantum spin liquid, or QSL, state existed on some triangular lattices, but he lacked the tools to delve deeper. Fifty years later, a team has confirmed the presence of QSL behavior in a new material with this structure, KYbSe2.

New study reveals huge potential for future waves of invasive species      (via sciencedaily.com)     Original source 

Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.

Climate change effects hit marine ecosystems in multiple waves, according to marine ecologists      (via sciencedaily.com)     Original source 

A new approach to examining the effects of climate change on marine ecosystems may provide a more accurate understanding of climate change responses -- and predictions for future consequences -- according to a new article. The paper highlights the interplay between the trend of climate warming and the fluctuations in local temperature. These two properties cause atypically warm events such as marine heatwaves to occur with increasing frequency and magnitude.
