Econophysics: Why Physicists are rewriting the rules of finance

Physicists are now using scientific theories to study financial markets and complex economic systems. Kishan Jaiswal, a student at Shri Ram College of Commerce between 2022 and 2026, explored this field. He said, “You walk me through the physics, and I’ll walk you through the finance. Together, we’ll build the bridge.”

What the evidence says

A 2025 Scientific Reports study shows Kashmiris are an indigenous population with deep local roots and West Eurasian links. Research on ancient DNA from Burzahom and medical data on genetic mutations revealed that the valley acted as a bridge between South and Central Asia, connecting people across mountain corridors.

A hidden black hole stayed invisible until it destroyed a passing star, revealing a cosmic mystery

Astronomers identified a dormant supermassive black hole 30,000 light-years from its galaxy's center on July 27, 2026. The object revealed itself by destroying a passing star. Suvi Gezari said, "What's new is that, until now, we've started with the assumption that supermassive black holes reside in the centers of massive galaxies."

The planet that spins the wrong way: Why Venus broke the Solar System's biggest rule and still has no clear explanation

Venus rotates in the opposite direction compared to other planets in the Solar System, puzzling astronomers for decades. While most planets spin from west to east, Venus moves backwards. Scientists think a massive collision with a large object during the early days of the Solar System caused this unusual movement.

Milky Way-like simulation reveals how central galactic structures grow together

A new simulation shows how Milky Way-like galaxies grow central star clusters and disks together. Researcher Dr. SungWon Kwak said, "Our simulation achieves this by showing how the galactic bar acts like a cosmic conveyor belt." This process channels gas inward, feeding both structures over four billion years of growth.

Trillion-mile gas streamer may explain tilt of triple-star system's outer planet-forming ring

Astronomers using the Atacama Large Millimeter/submillimeter Array captured a trillion-mile gas streamer feeding the triple-star system GW Orionis. Maria Galloway-Sprietsma said, "When our team modeled the infall of this streamer, we found that the angle at which it impacts the disk is closely aligned with the outer ring." This explains tilted rings.

Never-before-seen woven structure that forms naturally inside a crystal discovered

Scientists observed a three-dimensional woven structure forming naturally inside a crystal for the first time. Published in Light: Science & Applications, the study showed how dipoles weave together like fabric. The authors said, "This is the first time anyone has observed a woven structure emerging spontaneously inside a solid crystal."

One ant can trigger colony-wide activity bursts, mathematical model suggests

New research from New York University and the New Jersey Institute of Technology shows one ant can trigger colony-wide activity bursts. Scientists used a mathematical model to explain these synchronized waves. Lead author Michael Napoli said, "Activity bursts emerge as a balance between the responsiveness of the colony to the first ant."

An elegant modification doubles the range of low-noise 'white lasers' in a single fiber

Researchers at DTU Electro doubled the range of low-noise white lasers using a single fiber. Their study in Optica showed the system spans 0.86 to 2.90 micrometers. Andrea Arduin said, "What we have shown is that you can push the spectral width significantly without paying the price in noise."

This is a photo of the Sun, and it can answer a big question about our star

The NSF's Daniel K. Inouye Solar Telescope captured new whirlpools on the Sun in April 2025. These plasma vortices, known as Kelvin-Helmholtz instabilities, appear across the solar surface. Dr Friedrich Wöger said, "These are the highest spatial resolution images of the solar surface ever acquired." These findings help explain solar heat.

India’s flood crisis is 'complicated,' but new tech is finally offering families a fighting chance.

Assam and Kerala face severe monsoon floods that have killed dozens of people across India. Kerala now uses AI, IoT sensors, and community-based systems to improve flood preparedness. Meanwhile, Assam continues to struggle with the mighty Brahmaputra river as heavy seasonal rains and flooding remain a complex, recurring national challenge.

Elon Musk negotiated to buy Russian intercontinental ballistic missiles. Here's why

Elon Musk travelled to Moscow in 2001 and 2002 to negotiate buying surplus Soviet-era missiles for a Mars mission. The plan failed because the missiles cost too much. This setback pushed Musk to start SpaceX in 2002. He decided to build his own rockets instead, which changed the space industry forever.
