Fundamental physics—let alone quantum physics—might sound complicated to many, but it can actually be applied to solve everyday problems. Imagine navigating to an unfamiliar place. Most people would suggest using GPS, but what if you were stuck in an underground tunnel where radio signals from satellites were not able to penetrate? That's where quantum sensing tools come in. USC Viterbi Information Sciences Institute researchers Jonathan Habif and Justin Brown, both from ISI's new Laboratory for Quantum-Limited Information, are working at making sensing instruments like atomic accelerometers smaller and more accurate so they can be used to navigate when GPS is down.

NASA's Historic Achievement: Parker Solar Probe's Closest-Ever Approach to the Sun

NASA's Historic Achievement: Parker Solar Probe's Closest-Ever Approach to the Sun

Introduction: In a monumental breakthrough for space science, NASA's Parker Solar Probe has successfully completed its closest-ever approach to the Sun, bringing us closer than ever before to unlocking the mysteries of our star. This milestone marks a significant achievement in space exploration and has profound implications for our understanding of the Sun’s behavior, its impact on our solar system, and even space weather.

The Parker Solar Probe Mission: Launched in 2018, the Parker Solar Probe was designed to journey into the Sun's atmosphere, known as the corona, to collect data about the Sun’s magnetic fields, solar wind, and energetic particles. This close encounter has never been attempted by any spacecraft before due to the extreme temperatures and radiation near the Sun.

What Does This Historic Close-Approach Mean? The Parker Solar Probe came within approximately 6.2 million kilometers of the Sun’s surface. To put this into perspective, this is seven times closer than the previous record-holder, NASA's earlier spacecraft. This proximity allows scientists to observe phenomena that have been beyond reach for decades.

Why Is This Important? Understanding the Sun’s behavior is critical not only for science but also for the future of space travel and life on Earth. Solar winds and solar flares can interfere with satellite communications, GPS systems, and even power grids. By studying the Sun up close, researchers hope to predict and mitigate the effects of space weather on technology here on Earth.

Technological Innovation: This incredible feat was made possible by the development of cutting-edge technology, including the spacecraft's carbon-composite shield, which can withstand temperatures exceeding 1,370°C (2,500°F). This shield protects the instruments onboard, allowing the probe to gather critical data even in such extreme conditions.

Implications for the Future: With this success, NASA is now positioned to make groundbreaking discoveries that could reshape our understanding of the solar system and space weather. The data collected by the Parker Solar Probe will be invaluable in helping scientists better understand the Sun’s activity, including its cycle of solar flares and coronal mass ejections (CMEs), which can have significant effects on Earth’s atmosphere and space systems.

Conclusion: NASA’s Parker Solar Probe is on the cutting edge of space exploration, providing us with an unprecedented opportunity to explore the Sun up close. As we continue to explore the cosmos, these discoveries offer valuable insights not just for scientific advancement but for our everyday lives as well. The future of space exploration is bright, and this achievement represents just the beginning of many exciting developments to come.

50 Million Years of Climate Change with Christina!

Have you ever thought about how dinosaurs lived on a warm, swampy Earth and how we live on one that’s cold enough to keep pretty much the entirety of Greenland and Antarctica buried under kilometers-thick sheets of solid ice and wondered, hmm, how did we get from there to here? The short answer is that it took 50 million years of declining atmospheric carbon dioxide concentrations and dropping temperatures, not to mention building an ice sheet or two. For the longer story of the last 50 million years of climate change, including some of the reasons why, catch this episode of our podcast with Dr De La Rocha! You’ll hear about plate tectonics and continental drift, silicate weathering, carbonate sedimentation, and the spectacular effects the growth of Earth’s ice sheets have had on Earth’s climate. There are also lessons here for where anthropogenic global warming is going and whether or not its effects have permanently disrupted the climate system. Fun fact: the total amount of climate change between 50 million years ago and now dwarfs what we’re driving by burning fossil fuels, and yet, what we’re doing is more terrifying, in that it’s unfolding millions of times faster.

Mars may have been habitable much more recently than thought

"Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for scientists investigating whether Mars was indeed once habitable, and if so, when.

The "when" question in particular has driven researchers in Harvard's Paleomagnetics Lab in the Department of Earth and Planetary Sciences. A new paper in Nature Communications makes their most compelling case to date that Mars' life-enabling magnetic field could have survived until about 3.9 billion years ago, compared with previous estimates of 4.1 billion years—so hundreds of millions of years more recently.

The study was led by Griffin Graduate School of Arts and Sciences student Sarah Steele, who has used simulation and computer modeling to estimate the age of the Martian "dynamo," or global magnetic field produced by convection in the planet's iron core, like on Earth. Together with senior author Roger Fu, the John L. Loeb Associate Professor of the Natural Sciences, the team has doubled down on a theory they first argued last year that the Martian dynamo, capable of deflecting harmful cosmic rays, was around longer than prevailing estimates claim."

Chinese Researchers have released the World’s First Fully Automated Processor Chip Design System based on Artificial Intelligence (AI) Technology, making AI-designed chips a reality. With its designs comparable to the performance of human experts across multiple key metrics, the system represents a significant step toward fully automated chip design, potentially revolutionizing how chips are designed and manufactured.

The system named QiMeng jointly released by the Institute of Computing Technology, Chinese Academy of Sciences (CAS) and the Institute of Software of CAS, were recently published on arXiv.org, the Science and Technology Daily reported on Tuesday.

The QiMeng works like an automated architect and builder for computer chips. Instead of engineers manually designing every component, it uses AI to handle both the hardware and software aspects of chip creation.

June 10, 2025, Aamir Khollam Representational Image of AI-Driven Chip Design Process in China. Михаил Руденко/iStock. InterestingEngineering.Com

Expected to transform the design paradigms for the hardware and software of processor chip, the system not only significantly reduces human involvement, enhances design efficiency and shortens development cycles, but also enables rapid, customized designs tailored to specific application scenarios – flexibly meeting the increasingly diverse demands of chip design, the Science and Technology Daily reported.

Processor chips are hailed as the “Crown Jewel” of modern science and technology, with their design processes being highly complex, precise, and requiring a very high level of expertise. Traditional processor chip design relies heavily on experienced expert teams, often involving hundreds of people and taking months or even years to complete, resulting in high costs and lengthy development cycles.

Meanwhile, with the development of emerging technologies such as AI, cloud computing and edge computing, market demands for specialized processor chips and their corresponding foundational software optimization are growing rapidly. However, the number of professionals engaged in the processor chip industry in China is severely insufficient to meet this increasing demand.

In response to these challenges, the QiMeng system leverages advanced AI technologies such as large models to realize automated CPU design. It can also automatically configure corresponding foundational software for the chip, including operating systems, compilers and high-performance kernel libraries, according to the report.
