What would the Earth look like to an alien civilization located light years away?      (via sciencedaily.com)     Original source 

What would the Earth look like to an alien civilization located light years away? A team of researchers has used crowd-sourced data to simulate radio leakage from mobile towers and predict what an alien civilization might detect from various nearby stars, including Barnard's star, six light years away from Earth.

A stormy, active sun may have kickstarted life on Earth      (via sciencedaily.com)     Original source 

The first building blocks of life on Earth may have formed thanks to eruptions from our Sun, a new study finds. A series of chemical experiments show how solar particles, colliding with gases in Earth's early atmosphere, can form amino acids and carboxylic acids, the basic building blocks of proteins and organic life.

'Zero plant extinction' is possible, says plant ecologist      (via sciencedaily.com)     Original source 

Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which includes training more plant experts, building an online 'metaherbarium,' and creating 'microreserves.'

Webb finds water vapor, but from a rocky planet or its star?      (via sciencedaily.com)     Original source 

Astronomers used NASA's James Webb Space Telescope to study a rocky exoplanet known as GJ 486 b. It is too close to its star to be within the habitable zone, with a surface temperature of about 800 degrees Fahrenheit (430 degrees Celsius). And yet, their observations show hints of water vapor.

Astronomers detect 'nearby' black hole devouring a star      (via sciencedaily.com)     Original source 

Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest tidal disruption event observed to date, and one of the first to be identified at infrared wavelengths.

Early-nesting ducks at increased risk due to changes in climate, land use      (via sciencedaily.com)     Original source 

Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.

Ant mounds are more important for biodiversity than previously thought      (via sciencedaily.com)     Original source 

The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.

Most massive touching stars ever found will eventually collide as black holes      (via sciencedaily.com)     Original source 

A new study looked at a known binary star (two stars orbiting around a mutual center of gravity), analyzing starlight obtained from a range of ground- and space-based telescopes. The researchers found that the stars, located in a neighboring dwarf galaxy called the Small Magellanic Cloud, are in partial contact and swapping material with each other, with one star currently 'feeding' off the other. They orbit each other every three days and are the most massive touching stars (known as contact binaries) yet observed.

Direct image of a black hole expelling a powerful jet      (via sciencedaily.com)     Original source 

Astronomers have observed, in one image, the shadow of the black hole at the center of the galaxy Messier 87 (M87) and the powerful jet expelled from it. Thanks to this new image, astronomers can better understand how black holes can launch such energetic jets.

How the Amazon rainforest is likely to cope with the effect of future drought      (via sciencedaily.com)     Original source 

A major collaboration involving 80 scientists from Europe and South America has identified the regions of the Amazon rainforest where trees are most likely to face the greatest risk from drier conditions brought about by climate change. Based on the analysis, the scientists predict trees in the western and southern Amazon face the greatest risk of dying. They also warn that previous scientific investigations may have underestimated the impact of drought on the rainforest because those studies focused on the central-eastern part of the forest, which is the least vulnerable to drought.

Abundance of urban honeybees adversely impacts wild bee populations      (via sciencedaily.com)     Original source 

Researchers argue that the rapid growth in urban honeybee-keeping over the past decade may be negatively impacting nearby wild bee populations. Small bees with limited foraging ranges may be especially at risk, they write.

Astronomers solve the 60-year mystery of quasars -- the most powerful objects in the Universe      (via sciencedaily.com)     Original source 

Scientists have unlocked one of the biggest mysteries of quasars -- the brightest, most powerful objects in the Universe -- by discovering that they are ignited by galaxies colliding.

Medium-sized black holes eat stars like messy toddlers      (via sciencedaily.com)     Original source 

In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, intermediate-mass black holes likely devour wayward stars like a messy toddler -- taking a few bites and then flinging the remains across the galaxy.

Woodpecker guides post-fire forest management      (via sciencedaily.com)     Original source 

What's good for the Black-backed Woodpecker is good for restoration of burned California forests. The birds' unique relationship with fire underpins the latest research into improved post-fire management. A study describes a new tool that factors in how fires burn into forest management decisions and turns science into action for wildlife conservation.

Astrophysicists reveal the nature of dark matter through the study of crinkles in spacetime      (via sciencedaily.com)     Original source 

Astrophysicists have provided the most direct evidence yet that Dark Matter does not constitute ultramassive particles as is commonly thought but instead comprises particles so light that they travel through space like waves. Their work resolves an outstanding problem in astrophysics first raised two decades ago: why do models that adopt ultramassive Dark Matter particles fail to correctly predict the observed positions and the brightness of multiple images of the same galaxy created by gravitational lensing?
