Most massive stellar black hole in our galaxy found      (via sciencedaily.com)     Original source 

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency's Gaia mission because it imposes an odd 'wobbling' motion on the companion star orbiting it. Astronomers have verified the mass of the black hole, putting it at an impressive 33 times that of the Sun.

Twisted pollen tubes induce infertility      (via sciencedaily.com)     Original source 

Plants with multiple sets of chromosomes, known as polyploids, are salt-tolerant or drought-resistant and often achieve higher yields. However, newly formed polyploid plants are often sterile or have reduced fertility and are unsuitable for breeding resistant lines. The reason is that the pollen tube in these plants grows incorrectly, which keeps fertilization from taking place. Pollen tube growth is mainly controlled by two genes that could be useful in crop breeding.

'One ring to rule them all': How actin filaments are assembled by formins      (via sciencedaily.com)     Original source 

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing filament. Furthermore, the scientists elucidated the reasons for the different speeds at which the different formins promote this process.

How Pluto got its heart      (via sciencedaily.com)     Original source 

The mystery of how Pluto got a giant heart-shaped feature on its surface has finally been solved by an international team of astrophysicists. The team is the first to successfully reproduce the unusual shape with numerical simulations, attributing it to a giant and slow oblique-angle impact.

Millions of gamers advance biomedical research      (via sciencedaily.com)     Original source 

4.5 million gamers around the world have advanced medical science by helping to reconstruct microbial evolutionary histories using a minigame included inside the critically and commercially successful video game, Borderlands 3. Their playing has led to a significantly refined estimate of the relationships of microbes in the human gut. The results of this collaboration will both substantially advance our knowledge of the microbiome and improve on the AI programs that will be used to carry out this work in future.

Green-to-red transformation of Euglena gracilis using bonito stock and intense red light      (via sciencedaily.com)     Original source 

Euglena gracilis, often regarded as a 'superfood,' is a promising microalga with many health and nutritional benefits. In a recent study, researchers found an efficient and low-resource approach to trigger a reddening reaction in E. gracilis using red light and a bonito fish-based culture medium. This reaction is a sign of higher and diverse carotenoid content ratio, meaning the proposed method could help turn E. gracilis into an even more nutritious food source.

Even the simplest marine organisms tend to be individualistic      (via sciencedaily.com)     Original source 

Sport junkie or couch potato? Always on time or often late? The animal kingdom, too, is home to a range of personalities, each with its own lifestyle. Biologists report on a surprising discovery: even simple marine polychaete worms shape their day-to-day lives on the basis of highly individual rhythms. This diversity is of interest not just for the future of species and populations in a changing environment, but also for medicine.

How seaweed became multicellular      (via sciencedaily.com)     Original source 

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.

Brightest gamma-ray burst of all time came from the collapse of a massive star      (via sciencedaily.com)     Original source 

In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.

Innovative antiviral defense with new CRISPR tool      (via sciencedaily.com)     Original source 

The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: Cas13d-NCS. This new molecular tool allows CRISPR RNA molecules that are located within the nucleus of a cell to move to the cytoplasm, making it highly effective at neutralizing RNA viruses. This advancement opens doors for precision medicine and proactive viral defense strategies.

PFAS exposure from high seafood diets may be underestimated      (via sciencedaily.com)     Original source 

A study suggests that people with diets high in seafood may face a greater risk of exposure to PFAS -- the family of human-made toxins known as 'forever chemicals' -- than previously thought. The researchers stress the need for more stringent public health guidelines that establish how much seafood people can safely consume to limit their exposure, particularly in coastal areas where seafood is frequently eaten.

Beautiful nebula, violent history: Clash of stars solves stellar mystery      (via sciencedaily.com)     Original source 

When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system's fate.
