A Milky Way collision with a supermassive black hole might be closer than we thought.
Hidden deep in the Large Magellanic Cloud dwarf galaxy that orbits the Milky Way on an ever-closing loop, signs of a massive invisible object clocking in at around 600,000 times the mass of the Sun have been detected.
Since the Large Magellanic Cloud will one day collide with our own galaxy, that means the black hole is also destined to come crashing in.
Researchers have discovered that superconducting nanowire photon.
A photon is a particle of light. It is the basic unit of light and other electromagnetic radiation, and is responsible for the electromagnetic force, one of the four fundamental forces of nature. Photons have no mass, but they do have energy and momentum. They travel at the speed of light in a vacuum, and can have different wavelengths, which correspond to different colors of light. Photons can also have different energies, which correspond to different frequencies of light.
Abstract: Leveraging Multi-modal Large Language Models (MLLMs) to create embodied agents offers a promising avenue for tackling real-world tasks. While language-centric embodied agents have garnered substantial attention, MLLM-based embodied agents remain underexplored due to the lack of comprehensive evaluation frameworks. To bridge this gap, we introduce EmbodiedBench, an extensive benchmark designed to evaluate vision-driven embodied agents. EmbodiedBench features: a diverse set of 1,128 testing tasks across four environments, ranging from high-level semantic tasks (e.g., household) to low-level tasks involving atomic actions (e.g., navigation and manipulation); and six meticulously curated subsets evaluating essential agent capabilities like commonsense reasoning, complex instruction understanding, spatial awareness, visual perception, and long-term planning. Through extensive experiments, we evaluated 13 leading proprietary and open-source MLLMs within EmbodiedBench. Our findings reveal that: MLLMs excel at high-level tasks but struggle with low-level manipulation, with the best model, GPT-4o, scoring only 28.9% on average. EmbodiedBench provides a multifaceted standardized evaluation platform that not only highlights existing challenges but also offers valuable insights to advance MLLM-based embodied agents.

Our entire reality could – in theory – be built on a bed of sand, teetering on the brink of collapse. If so, a new device developed by a collaboration of physicists in Europe might give us some idea of how it all ends.
Using a process known as quantum annealing, the researchers have provided a proof-of-concept method to study the dynamics of a terrifying kind of reality-decay that would pull at the threads of physics, causing them to unravel.
Were such an event to occur somewhere in the cosmos, the quantum laws that lend structure to matter would be rewritten at the speed of light, spelling an end to all reality as we know it.
The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state (i.e., in which waves or particles are spread out) to a localized state, in which they are trapped in specific regions. This state was first studied by physicist Philip W. Anderson, who examined the arrangement of electrons in disordered solids, yet it was later found to also apply to the propagation of light and other waves.
Researchers at Missouri University of Science & Technology, Yale University, and Grenoble Alpes University in France recently set out to further explore the Anderson transition for light (i.e., electromagnetic waves) in 3D disordered systems.
Their paper, published in Physical Review Letters, outlines the simulation of light wave transport in an arrangement of perfect-electric-conducting (PEC) spheres, materials that reflect electromagnetic waves.

Divorce, the legal dissolution of marriage, can be driven by a variety of factors, ranging from changes in the economic status or health conditions of spouses to contrasting values. The end of a marriage can often be challenging to process. Thus, it can have adverse effects on the well-being and mental health of ex-spouses.
On average, the rates of divorce worldwide have increased over the past century. Improved understanding of the primary factors that prompt people to dissolve a marriage could help to devise more effective couples and marriage counseling strategies, potentially contributing to a reduction in divorce rates.
Sari Mentser and Lilach Sagiv, two researchers at the Hebrew University of Jerusalem, recently carried out a study specifically exploring the relationship between people’s values and divorce. Their findings, published in Communications Psychology, suggest that interaction between spouses’ cultural and personal values can predict divorce.
