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.

How can Europe restore its nature?      (via sciencedaily.com)     Original source 

Early 2024, the European Parliament will take a final vote on the 'Nature Restoration Law' (NRL), a globally unique but hotly debated regulation that aims to halt and reverse biodiversity loss in Europe. An international team of scientists has investigated the prospects of the new regulation.

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.

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.

Aquatic insects in restored streams need more rocks to lay their eggs      (via sciencedaily.com)     Original source 

Likening it to providing more runways at busy airports, researchers at North Carolina State University found in a new study that adding protruding rocks to restored streams can help attract female aquatic insects that lay their eggs on the rock bottoms or sides.

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.

Twenty-year study confirms California forests are healthier when burned -- or thinned      (via sciencedaily.com)     Original source 

A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.

The configuration of green spaces in cities determines the characteristics of their birds      (via sciencedaily.com)     Original source 

An international study has analyzed the distribution of 115 species of birds in spring and 72 that spend the winter in different cities. The study provides information on how to design urban areas that favor biodiversity and public wellbeing.

When is an aurora not an aurora?      (via sciencedaily.com)     Original source 

While auroras occur at high latitude, the associated phenomena Steve and the picket fence occur farther south and at lower altitude. Their emissions also differ from aurora. A physics graduate student has proposed a physical mechanism behind these emissions, and a rocket launch to test the theory. She argues that an electric field in the upper atmosphere parallel to Earth's magnetic field could explain the green picket fence spectrum and perhaps Steve and the enhanced aurora.

Scholars say it's time to declare a new epoch on the moon, the 'lunar Anthropocene'      (via sciencedaily.com)     Original source 

According to anthropologists and geologists, it's time to acknowledge humans have become the dominant force shaping the moon's environment by declaring a new geological epoch for the moon: the Lunar Anthropocene. They argue the new epoch may have dawned in 1959 when the USSR's unmanned spacecraft Luna 2 alighted on the lunar surface.

Urbanization increases seasonal differences in plant-pollinator networks      (via sciencedaily.com)     Original source 

Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.

Researchers develop grassroots framework for managing environmental commons      (via sciencedaily.com)     Original source 

A team of sustainability scientists recently announced that they have developed a community-based framework, founded on extensive local and traditional knowledge, to help assess and respond to the kinds of ecological threats that are widely dispersed across a varied landscape and whose solutions are not immediately obvious. The framework, which was developed to address watershed issues in Honduras's Lake Yojoa, is widely applicable to a broad range of threats facing ecological commons wherever they may occur around the world.
