Published IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
(via sciencedaily.com) 
Scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date.
Published Ambrosia beetles breed and maintain their own food fungi
(via sciencedaily.com)
Original source 
A recent experiment provides evidence of a bark beetle species' agricultural capability. The fruit-tree pinhole borer can suppress the growth of weed fungi and promote food fungi.
Published Uncovering the massive quantum mysteries of black holes
(via sciencedaily.com) 
Bizarre quantum properties of black holes -- including their mind-bending ability to have different masses simultaneously -- have been confirmed by physicists.
Published ESO captures the ghost of a giant star
(via sciencedaily.com) 
A beautiful tapestry of colors, showing the ghostly remains of a gigantic star, was captured in incredible detail with the VLT Survey Telescope, hosted at the European Southern Observatory's Paranal site in Chile.
Published El Niño increases seedling mortality even in drought-tolerant forests
(via sciencedaily.com)
Original source 
Scientists conducted a 7-year study on seedling recruitment and mortality in a national park in Chiang Mai, in northern Thailand. During the study period, an extremely strong El Niño event occurred, leading to a stronger and longer drought than normal. Seasonally dry tropical forests (SDTFs), which experience an annual dry season, are considered drought-tolerant. Nevertheless, the study found that seedling mortality increased in SDTFs when severe and prolonged drought occurred.
Published Life cycle of tree roots
(via sciencedaily.com)
Original source 
Scientists have developed a method for the direct observation of fine roots, which control the uptake of nutrients and water by trees. This provides a valuable addition to the existing knowledge of carbon and nutrient cycling in the forest floor, leading to further understanding of the carbon cycle from the view point of initial carbon input into the soil and aiding forest management and soil conservation.
Published UV-to-red light converting films accelerate plant growth
(via sciencedaily.com)
Original source 
Plastic sheets coated with an Eu3+ film that converts UV light to red light were able to accelerate growth of vegetal plants and trees.
Published Tree rings offer insight into devastating radiation storms
(via sciencedaily.com) 
A new study has shed new light on a mysterious, unpredictable and potentially devastating kind of astrophysical event.
Published Cosmic rays drive galaxy's winds
(via sciencedaily.com) 
VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.
Published By leaving garden waste alone, we could store 600,000 tons of CO2 per year
(via sciencedaily.com)
Original source 
Danes shuttle nearly a million tons of garden waste from their gardens every year. But we would be doing the climate a great service if we just left it alone, according to the new calculations. At the same time, leaves and other garden waste are a boon for backyard biodiversity and soil.
Published Ancient bacteria might lurk beneath Mars' surface
(via sciencedaily.com) 
Scientists found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. So, if life did, in fact, evolve when the last waters flowed on Mars, it would likely still be there today -- billions of years later.
Published Forest recovery after Montana's 2017 fire season
(via sciencedaily.com)
Original source 
Researchers found thousands of seedlings growing after recent fires in Montana, especially at sites with cooler, damper conditions -- often found in the shade of the dead trees and upper canopy, as well as on the north side of mountains with higher elevations and more undergrowth. Researchers found fewer seedlings at sites with less shade and drier, hotter conditions.
Published Discovery could dramatically narrow search for space creatures
(via sciencedaily.com) 
An Earth-like planet orbiting an M dwarf -- the most common type of star in the universe -- appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.
Published Looking to move to a galaxy far, far away? Innovative system evaluates habitability of distant planets
(via sciencedaily.com) 
The research framework developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those planets.
Published Unprecedented glimpse of merging galaxies
(via sciencedaily.com)
Original source 
Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.
Published New way to make telescope mirrors could sharpen our view of the universe
(via sciencedaily.com) 
Researchers have developed a new way to use femtosecond laser pulses to fabricate the high-precision ultrathin mirrors required for high-performance x-ray telescopes. The technique could help improve the space-based x-ray telescopes used to capture high-energy cosmic events involved in forming new stars and supermassive black holes.
Published NASA's Webb takes star-filled portrait of pillars of creation
(via sciencedaily.com)
Original source 
NASA's James Webb Space Telescope has captured a lush, highly detailed landscape -- the iconic Pillars of Creation -- where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear -- at times -- semi-transparent in near-infrared light.
Published The most precise accounting yet of dark energy and dark matter
(via sciencedaily.com) 
Analyzing more than two decades' worth of supernova explosions convincingly bolsters modern cosmological theories and reinvigorates efforts to answer fundamental questions.
Published NASA's Swift, Fermi missions detect exceptional cosmic blast
(via sciencedaily.com) 
Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB) -- the most powerful class of explosions in the universe -- that ranks among the most luminous events known.
Published Heaviest element yet detected in an exoplanet atmosphere
(via sciencedaily.com) 
Astronomers have discovered the heaviest element ever found in an exoplanet atmosphere -- barium. They were surprised to discover barium at high altitudes in the atmospheres of the ultra-hot gas giants WASP-76 b and WASP-121 b -- two exoplanets, planets which orbit stars outside our Solar System. This unexpected discovery raises questions about what these exotic atmospheres may be like.
