Researchers invent 'methane cleaner': Could become a permanent fixture in cattle and pig barns      (via sciencedaily.com)     Original source 

In a spectacular new study, researchers have used light and chlorine to eradicate low-concentration methane from air. The result gets us closer to being able to remove greenhouse gases from livestock housing, biogas production plants and wastewater treatment plants to benefit the climate.

15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

Scientists measure the distance to stars by their music      (via sciencedaily.com)     Original source 

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and checked the measurements taken during the Gaia mission to study the near Universe.

Astronomers discover first population of binary stripped stars      (via sciencedaily.com)     Original source 

Astronomers have discovered a population of massive stars that have been stripped of their hydrogen envelopes by their companions in binary systems. The findings shed light on the hot helium stars that are believed to be the origins of hydrogen-poor core-collapse supernovae and neutron star mergers.

Reaching for the (invisible) stars      (via sciencedaily.com)     Original source 

Supernovae -- stellar explosions as bright as an entire galaxy -- have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, scientists may have found the missing precursor star population.

Move over Blitzen: Geese outpace reindeer impacts on Arctic ecosystems      (via sciencedaily.com)     Original source 

A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.

Unexpected chemistry reveals cosmic star factories' secrets      (via sciencedaily.com)     Original source 

Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into individual colors, the scientists were amazed to discover light from many different molecules -- more than ever before at such distances. Studies like this could revolutionize our understanding of the lives of the most active galaxies when the universe was young, the researchers believe.

Tiniest free-floating brown dwarf      (via sciencedaily.com)     Original source 

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable with giant planets, weighing just a few times the mass of Jupiter.

Trees in wetter regions more sensitive to drought      (via sciencedaily.com)     Original source 

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.

Wildfires also impact aquatic ecosystems      (via sciencedaily.com)     Original source 

Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for fisheries and water quality.

How forests smell -- a risk for the climate?      (via sciencedaily.com)     Original source 

Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.

The solar forest      (via sciencedaily.com)     Original source 

What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.

Study overturns conventional wisdom about wild turkey nesting survival      (via sciencedaily.com)     Original source 

A new study finds that precipitation levels during nesting season are not related to reproductive success for wild turkeys, which runs counter to the conventional wisdom regarding the role that rainfall plays in wild turkey nesting success. The findings shed new light on how climate change may affect wild turkey populations.

Some icy exoplanets may have habitable oceans and geysers      (via sciencedaily.com)     Original source 

A new study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, beneath icy shells. Water from these oceans could occasionally erupt through the ice crust as geysers. The science team calculated the amount of geyser activity on these exoplanets, the first time these estimates have been made. They identified two exoplanets sufficiently close where signs of these eruptions could be observed with telescopes.

Nature and animal emojis don't accurately represent natural biodiversity      (via sciencedaily.com)     Original source 

The current emoji library doesn't accurately represent the 'tree of life' and the breadth of biodiversity seen in nature according to a new analysis. A team of conservation biologists categorized emojis related to nature and animals and mapped them onto the phylogenetic tree of life. They found that animals are well represented by the current emoji catalog, whereas plants, fungi, and microorganisms are poorly represented. Within the animal kingdom, vertebrates were over-represented while arthropods were underrepresented with respect to their actual biodiversity.
