New algae species rewrites understanding of reef systems      (via sciencedaily.com)     Original source 

An international team of marine scientists has identified and officially named four species of algae new to science, challenging previous taxonomical assumptions within the Porolithon genus. The discovery has far-reaching implications for our understanding of the ecological role of these algae in the coral reef ecosystem.

Mystery resolved: Black hole feeding and feedback at the center of an active galaxy      (via sciencedaily.com)     Original source 

Almost every large galaxy has a supermassive black hole at its center. An international research team has recently observed the Circinus galaxy, which is one of the closest galaxies to the Milky Way, with high enough resolution to gain further insights into the gas flows to and from the black hole at its galactic nucleus.

Fossils tell tale of last primate to inhabit North America before humans      (via sciencedaily.com)     Original source 

Paleontologists have shed light on the long-standing saga of Ekgmowechashala, based on fossil teeth and jaws found in both Nebraska and China. Ekgmowechashala is the last primate found in the fossil record before humans.

Frogs were Florida's first-known vertebrates from the Caribbean      (via sciencedaily.com)     Original source 

A new fossil study shows that frogs from the genus Eleutherodactylus are geologically the oldest Caribbean vertebrates to be found in Florida. They made the journey 20 million years ago, when much of Florida was still underwater.

Crust-forming algae are displacing corals in tropical waters worldwide      (via sciencedaily.com)     Original source 

Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.

Black holes are messy eaters      (via sciencedaily.com)     Original source 

New observations down to light-year scale of the gas flows around a supermassive black hole have successfully detected dense gas inflows and shown that only a small portion (about 3 percent) of the gas flowing towards the black hole is eaten by the black hole. The remainder is ejected and recycled back into the host galaxy.

Adult coral can handle more heat and keep growing thanks to heat-evolved symbionts      (via sciencedaily.com)     Original source 

Adult fragments of a coral species can better tolerate bleaching and recover faster when treated with tougher heat-evolved symbionts, new research indicates. The study also found that treatment with the heat-evolved symbionts did not compromise the coral's ability to grow. This differs from previous studies on Great Barrier Reef corals which found that naturally heat tolerant symbionts could enhance heat resistance in adult corals, but at a cost to its growth.

Researchers find gravitational lensing has significant effect on cosmic birefringence      (via sciencedaily.com)     Original source 

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into account the gravitational lensing effect, reports a new study.

Exploding stars      (via sciencedaily.com)     Original source 

When massive stars or other stellar objects explode in the Earth's cosmic neighborhood, ejected debris can also reach our solar system. Traces of such events are found on Earth or the Moon and can be detected using accelerator mass spectrometry, or AMS for short.

'Jurassic worlds' might be easier to spot than modern Earth      (via sciencedaily.com)     Original source 

An analysis finds telescopes could better detect potential chemical signatures of life in an Earth-like exoplanet that more closely resembles the age the dinosaurs inhabited than the one we know today.

Buzz around new centralized pollination portal for better global bee data      (via sciencedaily.com)     Original source 

A powerful new way to fill major gaps in public bee data -- including from Africa, Asia and other under-reported zones -- has been addressed with a centralized tool for consolidating bee pollinator occurrences around the globe.

Advanced assisted reproduction in white rhinos is safe and reliable, shows evaluation of procedures      (via sciencedaily.com)     Original source 

The BioRescue project develops and pioneers advanced assisted reproduction technologies (aART) for conservation in the face of the imminent extinction of most rhino species and subspecies. In a new scientific analysis, the team evaluated 65 aART procedures conducted from 2015 to 2022. The evaluation showed that aART is safe for the donor females with no detrimental health effects, and successful in that it yielded 51 embryos.

Giant planets cast a deadly pall      (via sciencedaily.com)     Original source 

Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates.

New map of 20th century land use in Britain helps researchers demystify biodiversity change      (via sciencedaily.com)     Original source 

Researchers have mapped how land use changed across Britain throughout the last century. The new map reveals how and where some 50 per cent of semi-natural grassland was lost, including 90 per cent of the country's lowland meadows and pasture, as the nation intensified its agriculture.

The Crab Nebula seen in new light by NASA's Webb      (via sciencedaily.com)     Original source 

NASA's James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. Since the recording of this energetic event in 1054 CE by 11th-century astronomers, the Crab Nebula has continued to draw attention and additional study as scientists seek to understand the conditions, behavior, and after-effects of supernovae through thorough study of the Crab, a relatively nearby example.

Amazon deforestation linked to long distance climate warming      (via sciencedaily.com)     Original source 

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.   The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.
