Scientists Smash Atoms to Smithereens, Revealing Hidden Nuclear Shapes

Posted by in categories: nuclear energy, particle physics

Scientists have developed a novel technique using high-energy particle collisions at the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research located at DOE’s Brookhaven National Laboratory. Detailed in a newly published paper in Nature, this method complements lower-energy approaches for studying nuclear structure. It offers deeper insights into the shapes of atomic nuclei, enhancing our understanding of the building blocks of visible matter.

“In this new measurement, we not only quantify the overall shape of the nucleus — whether it’s elongated like a football or squashed down like a tangerine — but also the subtle triaxiality, the relative differences among its three principle axes that characterize a shape in between the ‘football’ and ‘tangerine,’” said Jiangyong Jia, a professor at Stony Brook University (SBU) who has a joint appointment at Brookhaven Lab and is one of the principal authors on the STAR Collaboration publication.

Deciphering nuclear shapes has relevance to a wide range of physics questions, including which atoms are most likely to split in nuclear fission, how heavy atomic elements form in collisions of neutron stars, and which nuclei could point the way to exotic particle decay discoveries. Leveraging improved knowledge of nuclear shapes will also deepen scientists’ understanding of the initial conditions of a particle soup that mimics the early universe, which is created in RHIC’s energetic particle smashups. The method can be applied to analyzing additional data from RHIC as well as data collected from nuclear collisions at Europe’s Large Hadron Collider (LHC). It will also have relevance to future explorations of nuclei at the Electron-Ion Collider, a nuclear physics facility in the design stage at Brookhaven Lab.

Mystery Solved: Magnetars in Massive Galaxies Behind Cosmic Radio Flashes

Posted by in category: space

Researchers have linked the origins of fast radio bursts to magnetars, highly magnetized neutron stars, which often arise from the mergers of massive stars in star-forming galaxies.

By utilizing the Deep Synoptic Array-110, they’ve localized 70 FRBs, discovering that these bursts are more frequent in massive, metal-rich galaxies. This suggests that the environmental conditions conducive to FRB occurrence are also ideal for magnetar formation.

Introducing Daisy, The ‘AI Granny’ Outwitting Scammers

Posted by in categories: law enforcement, robotics/AI

Amid heated debates about the potential pitfills of artificial intelligence, the technology has finally taken a form we can probably all get behind — an “AI granny” created expressly to waste scammers’ time.

British telecom company Virgin Media O2 on Thursday introduced Daisy, a custom-made human-like chabot that answers calls in real time, keeping fraudsters on the phone as long as possible in a bid to annoy and frustrate them, just as they do to consumers worldwide. Daisy (that’s “dAIsy”) automates the practice of “scambaiting,” which involves people posing as potential victims to squander scammers’ time and resources, publicly expose their wily ways, gather information useful to law enforcement and even confuse the con artists’ devices.

Daisy, newly dubbed O2’s “head of scammer relations,” impersonates an older adult, making her part of a demographic that’s particularly vulnerable to scams. Unlike human scambaiters who need to sleep and shower once in a while, Daisy can spend all day and night on the phone with swindlers. “While they’re busy talking to me they can’t be scamming you, and let’s face it, dear, I’ve got all the time in the world,” Daisy says in the introductory video from O2 embedded below. The video personifies her as a photorealistic AI-generated woman with gray hair, glasses and pearls talking on a pink landline.

New model could calculate probability of intelligent life in our Universe and beyond

Posted by in categories: alien life, computing, information science, physics

A team of astrophysicists, led by our Institute for Computational Cosmology, have developed a new model that could estimate how likely it is for intelligent life to emerge in our Universe and beyond.

In the 1960s, American astronomer Dr Frank Drake came up with an equation to calculate the number of detectable extraterrestrial civilisations in our Milky Way galaxy.

More than 60 years on, researchers at Durham, the University of Edinburgh and the Université de Genève, have produced a new model based on the conditions created by the acceleration of the Universe’s expansion and the amount of stars formed instead.

Researchers have long observed that neurons in the brain tend to be organized in clusters, with neighboring neurons often sharing similar functions. This phenomenon is also seen in the brain’s language system, where certain areas respond to different aspects of language, such as syntax (sentence structure) or semantics (meaning). However, the exact mechanisms behind this organization remain a mystery.

Platelets gliding along surfaces: Using this concept to improve anti-thrombotic treatments

Posted by in category: biotech/medical

The risk for thrombosis on equipment within coronary arteries during PCI – and the potential dangerous complications – has led to nearly 50 years of targeted research on the mechanisms of normal and pathologic thrombosis. This research has in turn led to the development of blood-thinning drug treatments to prevent thrombosis during and after PCI. However, the blood thinning (‘anti-thrombotic’) therapies can also lead to life-threatening excessive bleeding. Research to identify the optimal balance of anti-thrombotic drugs that minimises both pathologic thrombosis and excessive bleeding continues through today.

Dr Scott Denardo at Duke University Medical Center in the USA has modelled the behaviour of platelets inside blood vessels and near medical device surfaces. Some of his observations are just now entering the contemporary understanding of thrombosis. Denardo believes that applying these observations can refine existing anti-thrombotic therapies to improve their safety (less bleeding) while not compromising their effectiveness (preventing thrombosis on PCI equipment, including stents).
