Astronomers witness vanishing star collapse into a black hole in Andromeda galaxy

Image
  Astronomers may have witnessed the birth of a brand-new black hole in our neighboring galaxy, offering one of the clearest glimpses yet of how some stars quietly collapse into these cosmic abysses without the usual fireworks of an explosion. While scouring archival data from NASA's NEOWISE mission, a team led by Columbia University astronomer Kishalay De discovered that one of the brightest stars in the Andromeda Galaxy mysteriously brightened over a decade ago, faded dramatically and then vanished from view. The star, labeled M31-2014-DS1, lay about 2.5 million light-years from Earth and weighed just 13 times the mass of our sun — relatively lightweight by typical black hole-forming standards, according to De and colleagues' research. "Observations like these are starting to finally change this long-held paradigm that it's only the very massive stars that turn into black holes If this detection holds up, he added, "then it really means that there are many more ...

Integrating Earth and Ecological Sciences with Artificial Intelligence

Image
In the epoch of rapid technological advancement, Artificial Intelligence (AI) has emerged as a transformative force across multiple disciplines, prominently including environmental science. The initiation of the journal “Artificial Intelligence & Environment” (AI&E) stands as a testament to this promising integration.  The scope of the journal is broad yet focused. It aims to enhance the methodological toolkit available to environmental scientists and practitioners by integrating cutting-edge AI strategies into various environmental contexts. Whether it’s ecological preservation, climate change mitigation, water management, pollution control, or sustainable development, AI&E is dedicated to facilitating research that not only deepens understanding but also engenders actionable solutions. As environmental challenges grow increasingly complex, so too must our approaches to addressing them. Thus, the journal will accept submissions from researchers worldwide, fostering a ...

Scientists discover new life forms inside human bodies, remarking 'it's insane'

Image
Every time we think we’re close to fully understanding the human body, something fresh and unexpected shows up. Recently, a team of researchers stumbled upon strange entities, or obelisks, living inside of human bodies that had escaped notice until now. Their surprising presence challenges assumptions and raises pressing questions about what else might be lurking unseen inside us. These new visitors appear smaller than the viruses most people learn about in basic biology classes. Rather than behaving like familiar microbes, they introduce themselves as something different. Their discovery came about when researchers began analyzing massive genetic libraries, searching for patterns that did not match any known organisms. Obelisks inside humans These obelisks do not resemble typical life forms, and their name comes from their distinctive shape. “It’s insane,” says Mark Peifer, a cell and developmental biologist at the University of North Carolina at Chapel Hill (UNC). “The more we look,...

Deceptive AI interactions can feel more deep and genuine than actual human conversations

Image
A new study published in Communications Psychology suggests that artificial intelligence systems can be more effective than humans at establishing emotional closeness during deep conversations, provided the human participant believes the AI is a real person. The findings indicate that while individuals can form social bonds with AI, knowing the partner is a machine reduces the feeling of connection. The rapid development of large language models has fundamentally altered the landscape of human-computer interaction. Previous observations have indicated that these programs can generate content that appears empathetic and similar to human speech. Despite these advancements, it remained unclear whether humans could form relationships with AI that are as strong as those formed with other people. This is particularly relevant during the initial stages of getting to know a stranger. Scientists aimed to fill this gap by investigating how relationship building differs between human partners and...

New fear unlocked: runaway black holes

Image
Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth’s speed around the Sun. Imagine if it had been something much bigger and faster: a black hole travelling at more like 3,000km per second. We wouldn’t see it coming until its intense gravitational forces started knocking around the orbits of the outer planets. This may sound a bit ridiculous – but in the past year several lines of evidence have come together to show such a visitor is not impossible. Astronomers have seen clear signs of runaway supermassive black holes tearing through other galaxies, and have uncovered evidence that smaller, undetectable runaways are probably out there too. Runaway black holes: the theory The story begins in the 1960s, when New Zealand mathematician Roy Kerr found a solution of Einstein’s general relativity equations that described spinning black holes. This led ...

Anomeric effect cannot be explained by hyperconjugation alone

Image
  Computational analysis suggests that the anomeric effect arises from a combination of factors and is not limited to just hyperconjugation. Researchers say that this ‘curiosity-driven’ work reminds chemists that attributing the effect to one dominant cause oversimplifies a ‘fundamentally complex phenomenon’. The anomeric effect helps chemists rationalise why substituents next to a heteroatom in a ring preferentially adopt an axial configuration, rather than the less sterically hindered equatorial orientation. Hyperconjugation of a heteroatom’s lone pair of electrons into the anti-bonding orbital of an adjacent substituent is a common explanation for this effect. However, previous studies suggest that other factors such as stereoelectronics and solvent interactions also play a part.1 Researchers at Florida State University in the US have now tried to quantify the influence of such factors.2 To do this, the team computationally analysed 49 monosubstituted tetrahydropyrans – rings wi...
