For the past 19 years, the Forensics Engineering Conference at UT Austin’s Cockrell School of Engineering has brought together the best of academia and industry for an exciting exchange on advances in forensics engineering.

The 2025 conference carries special importance, celebrating longtime Lead Faculty David Fowler, Ph.D., and his rich legacy. This year’s conference will be led by Ryan Kalina, Ph.D., P.E., vice president, Forensix Consulting and lecturer, Cockrell School Department of Civil, Architectural and Environmental Engineering.

The 2025 conference topics span real-world case studies, lessons from significant structural forensic failures, ethical issues and the impact of weather on structures. Sessions are presented by industry and academic engineering experts.

What do you think of when it comes to extra terrestrial life? Most popular sci-fi books and TV shows suggest humanoid beings could live on other planets. But when astronomers are searching for extra-terrestrial life, it is usually in the form of emissions from bacteria or other tiny organisms.

A new research paper in the Astrophysical Journal suggests that Cambridge scientists have managed to find this type of emission with a certainty of 99.7% from a planet called K2-18b, 124 light years away. They used NASA’s James Webb Space Telescope to analyze the chemical composition of the planet’s atmosphere and say they found promising evidence K2-18b could host life.

It’s an exciting breakthrough, but it doesn’t confirm alien life.

In a groundbreaking leap toward cleaner, more affordable energy, scientists in France held a fusion reaction steady for over 22 minutes — shattering the previous world record. If that number sounds insignificant, here’s why it’s a big deal: That is 1,337 seconds of controlled, blazing-hot plasma, the critical ingredient needed to power nuclear fusion, a nearly limitless energy source that does not rely on polluting fuels like gas, coal, or oil.

This milestone brings us one step closer to a dream energy future: one where our homes, cities, and electric cars are powered by a technology that mimics the sun — minus the radioactive waste and environmental damage of traditional nuclear power.

Nuclear fusion has the capability to solve a major problem with polluting energy sources. Right now, our power mostly comes from dirty energy that pollutes the air and contributes to extreme weather. While solar and wind energy are gaining momentum, fusion offers something different: the possibility of continuous, around-the-clock clean energy using hydrogen — the most common element in the universe — as fuel.

Quantum gravity is one of the biggest unresolved and challenging problems in physics, as it seeks to reconcile quantum mechanics, which governs the microscopic world, and general relativity, which describes the macroscopic world of gravity and space-time.

Efforts to understand quantum gravity have been focused almost entirely at the theoretical level, but Monika Schleier-Smith at Stanford University has been exploring a novel experimental approach — trying to create quantum gravity from scratch. Using laser-cooled clouds of atoms, she is testing the idea that gravity might be an emergent phenomenon arising from quantum entanglement.

In this episode of The Joy of Why podcast, Schleier-Smith discusses the thinking behind what she admits is a high-risk, high-reward approach, and how her experiments could provide important insights about entanglement and quantum mechanical systems even if the end goal of simulating quantum gravity is never achieved.

In this Perspective, the authors propose that patients with psoriatic arthritis and an inadequate response to therapy can be classified into two distinct subgroups, characterized by persistent inflammatory and non-inflammatory phenotypes, and discuss potential mechanisms underlying these phenotypes, as well as considerations for treatment strategies and trial design.

Many cells in our body have a single primary cilium, a micrometer-long, hair-like organelle protruding from the cell surface that transmits cellular signals. Cilia are important for regulating cellular processes, but because of their small size and number, it has been difficult for scientists to explore cilia in brain cells with traditional techniques, leaving their organization and function unclear.

In a new series of work, researchers at HHMI’s Janelia Research Campus, the Allen Institute, the University of Texas Southwestern Medical Center, and Harvard Medical School used super high-resolution 3D electron microscopy images of mouse brain tissue generated for creating connectomes to get the best look yet at primary cilia.
