New maps help decision-makers factor albedo into tree-planting decisions      (via sciencedaily.com)     Original source 

A new study provides a global analysis of where restoration of tree cover is most effective at cooling the global climate system, considering not just the cooling from carbon storage but also the warming from decreased albedo. The researchers provide a tool practitioners and land managers can use to determine just how much of a problem albedo is for any reforestation or afforestation project on the globe.

Seeing the forest for the trees: Species diversity is directly correlated with productivity in eastern U.S. forests      (via sciencedaily.com)     Original source 

When officials make tough calls on which areas to prioritize for conservation, biodiversity is often their top consideration. But there are several types of diversity, and not all of them overlap perfectly. In a new study, researchers analyzed 20-years' worth of U.S. Forest Service data and show that the simplest measure of diversity is the best predictor of healthy forest growth, providing a roadmap for quickly and efficiently protecting ecological resources.

Astronomers discover 49 new galaxies in under three hours      (via sciencedaily.com)     Original source 

New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.

Researchers discover evolutionary 'tipping point' in fungi      (via sciencedaily.com)     Original source 

Scientists have found a 'tipping point' in the evolution of fungi that throttles their growth and sculpts their shapes. The findings demonstrate how small changes in environmental factors can lead to huge changes in evolutionary outcomes.

James Webb Space Telescope captures the end of planet formation      (via sciencedaily.com)     Original source 

How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons      (via sciencedaily.com)     Original source 

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

Two of the Milky Way's earliest building blocks identified      (via sciencedaily.com)     Original source 

Astronomers have identified what could be two of the Milky Way's earliest building blocks: Named 'Shakti' and 'Shiva', these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy's initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city.

Rays were more diverse 150 million years ago than previously thought      (via sciencedaily.com)     Original source 

Scientists have explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity -- including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.

Species diversity promotes ecosystem stability      (via sciencedaily.com)     Original source 

What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.

Forest, stream habitats keep energy exchanges in balance, global team finds      (via sciencedaily.com)     Original source 

Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.

Scientists weigh up current status of blue whale populations around the world      (via sciencedaily.com)     Original source 

The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming, pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies and pygmy subspecies of the eastern Indian and western Pacific.

High school students contribute to exoplanet discovery      (via sciencedaily.com)     Original source 

A group of high school students from Oakland, California, made contributions to the field of exoplanet research. Researchers worked with the students to use backpack-sized digital smart telescopes. These young citizen scientists played a role in observing and confirming the nature of a warm and dense sub-Saturn planet, known as TIC 139270665 b, orbiting a metal-rich G2 star.

Scientists find one of the most ancient stars that formed in another galaxy      (via sciencedaily.com)     Original source 

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

Astrophysicist's research could provide a hint in the search for dark matter      (via sciencedaily.com)     Original source 

Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.
