Extraterrestrial chemistry with earthbound possibilities      (via sciencedaily.com)     Original source 

Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules, researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and environmental applications on our home planet.

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.

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.

New heaviest exotic antimatter nucleus      (via sciencedaily.com)     Original source 

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of the early universe -- have discovered a new kind of antimatter nucleus, the heaviest ever detected. Composed of four antimatter particles -- an antiproton, two antineutrons, and one antihyperon -- these exotic antinuclei are known as antihyperhydrogen-4.

Explanation found for X-ray radiation from black holes      (via sciencedaily.com)     Original source 

Researchers have succeeded in something that has been pursued since the 1970s: explaining the X-ray radiation from the black hole surroundings. The radiation originates from the combined effect of the chaotic movements of magnetic fields and turbulent plasma gas.

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.

Why do plants wiggle? New study provides answers      (via sciencedaily.com)     Original source 

Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow -- spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.

Galaxies in dense environments tend to be larger, settling one cosmic question and raising others      (via sciencedaily.com)     Original source 

A new study has found galaxies with more neighbors tend to be larger than their counterparts that have a similar shape and mass, but reside in less dense environments. The team, which used a machine-learning algorithm to analyze millions of galaxies, reports that galaxies found in denser regions of the universe are as much as 25% larger than isolated galaxies. The findings resolve a long-standing debate among astrophysicists over the relationship between a galaxy's size and its environment, but also raise new questions about how galaxies form and evolve over billions of years.

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.

Unlocking the secrets of salt stress tolerance in wild tomatoes      (via sciencedaily.com)     Original source 

As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
