A spectrum of possibilities: Insights into the evolution of far-red light photosynthesis      (via sciencedaily.com)     Original source 

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could pave the way for engineering plants with enhanced light absorption capabilities and has implications for our search for extraterrestrial life.

Composition of asteroid Phaethon      (via sciencedaily.com)     Original source 

Asteroid Phaethon, which is five kilometers in diameter, has been puzzling researchers for a long time. A comet-like tail is visible for a few days when the asteroid passes closest to the Sun during its orbit. However, the tails of comets are usually formed by vaporizing ice and carbon dioxide, which cannot explain this tail. The tail should be visible at Jupiter's distance from the Sun.

Solar activity likely to peak next year      (via sciencedaily.com)     Original source 

Researchers have discovered a new relationship between the Sun's magnetic field and its sunspot cycle, that can help predict when the peak in solar activity will occur. Their work indicates that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.

Slash-and-burn agriculture can increase forest biodiversity, researchers find      (via sciencedaily.com)     Original source 

The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.

New way of searching for dark matter      (via sciencedaily.com)     Original source 

Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which scientists never looked at before.

Alien haze, cooked in a lab, clears view to distant water worlds      (via sciencedaily.com)     Original source 

Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles important telescope observations for the search of habitable worlds beyond the solar system.

The Fens of eastern England once held vast woodlands      (via sciencedaily.com)     Original source 

The Fens of eastern England, a low-lying, extremely flat landscape dominated by agricultural fields, was once a vast woodland filled with huge yew trees, according to new research. Scientists have studied hundreds of tree trunks, dug up by Fenland farmers while ploughing their fields. The team found that most of the ancient wood came from yew trees that populated the area between four and five thousand years ago.

Telescope Array detects second highest-energy cosmic ray ever      (via sciencedaily.com)     Original source 

In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and the particle had more energy than was theoretically possible for cosmic rays traveling to Earth from other galaxies. Simply put, the particle should not exist. On May 27, 2021, the Telescope Array experiment detected the second-highest extreme-energy cosmic ray. The newly dubbed Amaterasu particle deepens the mystery of the origin, propagation and particle physics of rare, ultra-high-energy cosmic rays.

Researchers puncture 100-year-old theory of odd little 'water balloons'      (via sciencedaily.com)     Original source 

Quinoa and many other extremely resilient plants are covered with strange balloon-like 'bladders' that for 127 years were believed to be responsible for protecting them from drought and salt. Research results reveal this not to be the case. These so-called bladder cells serve a completely different though important function. The finding makes it likely that even more resilient quinoa plants will now be able to be bred, which could lead to the much wider cultivation of this sustainable crop worldwide.

NASA's Webb reveals new features in heart of Milky Way      (via sciencedaily.com)     Original source 

The latest image from NASA's James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way's central supermassive black hole, Sagittarius A*.

Looking for 'LUCA' and the timing of cellular evolution      (via sciencedaily.com)     Original source 

LUCA, the 'last universal common ancestor' of all living organisms, lived 4.32 to at most 4.52 billion years ago. What LUCA looked like is unknown, but it must have been a cell with among others ribosomal proteins and an ATP synthase.

Forest modeling shows which harvest rotations lead to maximum carbon sequestration      (via sciencedaily.com)     Original source 

Forest modeling shows that a site's productivity -- an indicator of how fast trees grow and how much biomass they accumulate -- is the main factor that determines which time period between timber harvests allows for maximum above-ground carbon sequestration.

Dwarf galaxies use 10-million-year quiet period to churn out stars      (via sciencedaily.com)     Original source 

If you look at massive galaxies teeming with stars, you might be forgiven in thinking they are star factories, churning out brilliant balls of gas. But actually, less evolved dwarf galaxies have bigger regions of star factories, with higher rates of star formation. Now, University of Michigan researchers have discovered the reason underlying this: These galaxies enjoy a 10-million-year delay in blowing out the gas cluttering up their environments. Star-forming regions are able to hang on to their gas and dust, allowing more stars to coalesce and evolve. In these relatively pristine dwarf galaxies, massive stars--stars about 20 to 200 times the mass of our sun--collapse into black holes instead of exploding as supernovae. But in more evolved, polluted galaxies, like our Milky Way, they are more likely to explode, thereby generating a collective superwind. Gas and dust get blasted out of the galaxy, and star formation quickly stops.

'Teenage galaxies' are unusually hot, glowing with unexpected elements      (via sciencedaily.com)     Original source 

Using the James Webb Space Telescope, CECILIA Survey receives first data from galaxies forming two-to-three billion years after the Big Bang. By examining light from these 33 galaxies, researchers discovered their elemental composition and temperature. The ultra-deep spectrum revealed eight distinct elements: Hydrogen, helium, nitrogen, oxygen, silicon, sulfur, argon and nickel. The teenage galaxies also were extremely hot, reaching temperatures higher than 13,350 degrees Celsius.
