Our sun, born 4.6 billion years ago near the crowded, chaotic heart of the Milky Way, did not make its journey to the galaxy’s calmer outer suburbs alone. A pair of new studies published March 12, 2026, in Astronomy and Astrophysics reveal that thousands of “solar twin” stars — stars with nearly identical mass, age and chemical composition to the sun — migrated outward alongside it in a coordinated stellar exodus spanning roughly 10,000 light-years.

Led by Daisuke Taniguchi of Tokyo Metropolitan University and Takuji Tsujimoto of the National Astronomical Observatory of Japan, the research draws on data from the European Space Agency’s Gaia space telescope, which has mapped positions, motions and compositions for billions of stars with unprecedented precision.

The team identified 6,594 solar twins in Gaia’s latest release, focusing on those matching the sun’s metallicity (a measure of elements heavier than helium) and age. Their orbital paths and chemical signatures point to a shared origin closer to the galactic center, followed by a synchronized outward drift that placed them in the sun’s current neighborhood — about 26,000 light-years from the Milky Way’s core.

Computer simulations had long suggested such a trek would be rare. Stars born in the dense inner regions face formidable barriers: intense radiation, frequent supernovae explosions and gravitational perturbations from the galaxy’s central bar and spiral arms. Models predicted only about 1 percent of stars from the sun’s presumed birthplace could reach the outer disk within 4.6 billion years without being destroyed or scattered.

Yet the Gaia data show thousands succeeded — far more than chance alone would allow. The researchers propose the explanation lies in a massive, galaxy-wide migration wave triggered by the formation and evolution of the Milky Way’s central bar roughly 4 to 6 billion years ago.

As the bar strengthened, it boosted star formation in the inner disk and launched large-scale radial migrations. Gravitational resonances — regions where orbital periods align with the bar’s rotation or spiral arms — funneled stars outward in groups rather than individually. The sun and its twins caught this wave, riding it to safer, less hazardous suburbs where cosmic rays and supernova blasts are less frequent.

This migration may help explain why Earth became habitable. The galactic center teems with dangers: gamma-ray bursts, black-hole activity and dense stellar crowds that could strip planetary atmospheres or trigger mass extinctions. By migrating outward just in time — before the solar system fully formed its planets — the sun escaped the worst risks, providing a stable environment for life to emerge.

Taniguchi told Live Science the pattern suggests “many solar twins of the same age migrated through the Milky Way around the same time as the sun, giving us new clues about when and how the sun moved from its birthplace to its current location.”

The studies build on decades of debate about the sun’s origins. Earlier work proposed the sun formed farther out or migrated via spiral-arm resonances, but the new evidence ties the movement to a specific galactic event: bar-driven migration.

Gaia’s third data release in 2022 and ongoing fourth-release updates have revolutionized stellar archaeology, allowing astronomers to rewind stellar orbits billions of years. By tracing chemical abundances — especially iron-peak elements forged in supernovae — researchers can fingerprint stars born in the same era and region.

The solar twins cluster in both kinematics (motion) and metallicity, supporting group migration over random drift. The wave likely peaked 4 to 6 billion years ago, coinciding with the sun’s youth and the Milky Way’s transition to a more stable barred-spiral structure.

Implications extend beyond our solar system. If many sun-like stars share this history, habitable zones may correlate with migration paths. Regions swept by such waves could host more life-friendly systems, as they escape inner-galaxy perils.

The findings also refine models of galactic evolution. The Milky Way’s bar, a peanut-shaped structure of older stars, drives radial mixing that reshapes the disk over cosmic time. Similar processes occur in other barred spirals, suggesting coordinated migrations are common.

No direct evidence links the migration to Earth’s habitability, but the timing aligns intriguingly. Planet formation took hundreds of millions of years after the sun’s birth; the outward journey may have positioned the nascent system in a quieter galactic suburb just as rocky worlds and oceans stabilized.

Future Gaia releases and upcoming telescopes like the Vera C. Rubin Observatory will test the hypothesis by mapping even fainter twins and refining orbital reconstructions.

For now, the studies paint a dynamic picture: the sun was not a solitary wanderer but part of a vast stellar caravan, carried by galactic forces to the peaceful outskirts where life could take root.

Astronomers say the work underscores how interconnected stellar lives are with their galaxy’s architecture — and how a timely migration may have been key to our existence.

Just Eat Takeaway.com is expanding its push towards sustainable food delivery packaging by introducing a new range of plastic-free takeaway boxes across ten European markets, using a plant-based coating designed to replace conventional plastic linings.

The food delivery giant confirmed that the packaging will be rolled out across Austria, Belgium, Bulgaria, Switzerland, Germany, Italy, the Netherlands, Poland, Slovakia and Spain, following earlier launches with its German brand Lieferando in Germany and Austria.

The initiative is part of a partnership with sustainable packaging manufacturer Huhtamaki and UK materials technology company Xampla, whose Morro Coating technology provides a plastic-free alternative to the thin polymer layers traditionally used to make takeaway containers resistant to grease and moisture.

Unlike conventional takeaway boxes, which rely on plastic coatings to prevent leaks and maintain structural integrity, the new packaging uses a coating derived from natural plant proteins that has not undergone chemical modification. The coating provides the same barrier performance required for takeaway food packaging while remaining fully recyclable within standard paper recycling systems.

The rollout reflects growing pressure on the food delivery and hospitality sectors to reduce reliance on single-use plastics, particularly as regulations tighten across Europe under measures such as the EU’s Single Use Plastics Directive (SUPD).

According to the companies involved, the Morro-coated boxes have been verified as plastic-free by the UK’s National Physical Laboratory, making them one of the first takeaway packaging solutions capable of delivering high-performance food protection without plastic barriers.

The packaging is made from sustainably sourced corrugated paperboard, designed to retain heat and maintain rigidity even when used with greasy or moisture-heavy dishes that traditionally require plastic-lined containers.

Industry experts say solving this challenge is key to reducing plastic waste across the food delivery sector, where millions of takeaway boxes are used daily and often end up in landfill because plastic coatings prevent recycling.

Alexandra French, chief executive of Xampla, said the European expansion demonstrates that natural materials are increasingly capable of replacing plastic in high-volume commercial applications.

“Europe is moving fast on packaging regulation, and the demand for materials that can genuinely replace plastic has never been stronger,” she said.

“There is strong environmental ambition across these markets and a willingness to adopt new materials when they work. For us, this rollout is about scale. We’ve proven Morro Coating works and now we’re bringing it to millions of takeaway meals across Europe.”

French added that large-scale adoption in sectors such as food delivery is critical if sustainable materials are to meaningfully replace plastic packaging.

“If we want to replace plastic, we need to do it in the most demanding environments, where packaging needs to perform under heat, grease and moisture. This expansion shows that natural materials can compete in exactly those conditions.”

Huhtamaki, which manufactures the packaging, said the technology integrates seamlessly with existing foodservice supply chains and recycling infrastructure, enabling restaurants to transition to more sustainable packaging without requiring changes to waste management processes.

Because the coating is free from plastic, the containers can be processed through established paper recycling streams without needing separation of materials, addressing one of the major barriers to recycling takeaway packaging.

The rollout also supports businesses navigating evolving environmental regulations, including extended producer responsibility (EPR) rules that are increasingly placing financial responsibility on companies for the environmental impact of their packaging.

For Just Eat Takeaway.com, the expansion is part of a broader sustainability strategy aimed at reducing plastic waste across the fast-growing food delivery industry.

A spokesperson for the company said the move would allow thousands of restaurant partners across Europe to adopt packaging that meets both environmental and regulatory expectations.

“We’re excited to work with innovative partners who share our vision of reducing single-use plastic waste and creating more responsible packaging solutions,” the company said.

“Expanding our collaboration with Xampla represents a significant milestone in accelerating the adoption of plastic-free packaging across the on-demand delivery industry.”

The announcement comes as food delivery platforms face increasing scrutiny over the environmental impact of takeaway packaging, which contributes significantly to urban waste streams across Europe.

By introducing recyclable, plant-based coatings capable of replacing plastic in food containers, the companies involved hope to demonstrate that large-scale alternatives to plastic packaging are both commercially viable and operationally practical.

With millions of takeaway orders processed across its European markets every week, Just Eat Takeaway.com’s adoption of plastic-free containers could represent one of the most significant real-world deployments of plant-based packaging technologies in the food delivery sector to date.

This story on the January 2026 PCE inflation report is developing and will be updated with more details.

The Federal Reserve’s preferred inflation gauge remained stubbornly high in January as consumers continued to face elevated price growth.

The Commerce Department on Friday reported that the personal consumption expenditures (PCE) index rose 0.3% on a monthly basis in January and is up 2.8% from a year ago. The monthly figure was in-line with the expectations of economists polled by LSEG, while the annual figure was slightly lower than the 2.9% estimate.

Core PCE, which excludes volatile measurements of food and energy prices, was up 0.4% from a month ago and increased 3.1% year over year. Both figures were in line with economists’ expectations from the LSEG poll.

Federal Reserve policymakers are focusing on the PCE headline figure as they try to bring inflation back to their long-run target of 2%, though they view core data as a better indicator of inflation. Compared with December’s readings, headline PCE inflation declined slightly from 2.9% while core PCE rose from 3%.

FED OFFICIALS CLOSELY MONITOR IRAN CONFLICT FOR POTENTIAL INFLATION IMPACT

Prices for goods were up 1.3% in January on an annual basis, down from 1.7% in December. Goods prices increases were even lower last summer, when the index posted annual gains of 0.6% in June and July and 0.9% in August.

Durable goods prices increased 2.2% in January from a year ago, up from a 2.1% reading in December. The index was close to 1% from June through November. Nondurable goods prices rose just 0.8% in January, a decline from the 1.6% annual rate recorded in December and the lowest reading since August.

What does it mean for the Fed?

Costco Wholesale COST 1.12%increase; green up pointing triangle is being sued by a shopper looking to get his tariff costs back. 

A lawsuit filed Wednesday in an Illinois federal court alleges that Costco owes its customers refunds related to tariffs deemed unlawful by the Supreme Court last month. The suit is seeking class-action status on behalf of Costco shoppers nationwide.  

Costco increased product prices to offset the cost of tariffs, but it hasn’t promised shoppers a refund, said the lawsuit filed on behalf of Matthew Stockov, a Costco member who lives in Illinois. Shoppers won’t get a government refund directly, because they aren’t the importer of record, said the lawsuit. “The truly injured parties possess no direct avenue for redress,” alleged the lawsuit, which asks Costco for a refund on price increases related to tariffs, plus interest.

A Costco spokesman said the company had no comment on the lawsuit. “Our commitment will be to find the best way to return this value to our members through lower prices and better values,” if the company receives tariff refunds, said Chief Executive Ron Vachris on an earnings call last week. It has taken a similar approach with past legal winnings, he said.

Entrepreneur and television personality Trinny Woodall has said artificial intelligence could become a powerful tool for women looking to advance in their careers, after pausing operations at her cosmetics company to train staff in AI skills.

Woodall temporarily halted normal activity at her Trinny London business for two days earlier this year so that around 150 employees could take part in an intensive artificial intelligence workshop, aimed at helping staff understand how emerging technologies could support both their current roles and future careers.

The training programme was delivered by Lichen AI, which introduced employees to the fundamentals of working with AI systems and how they can be integrated into everyday business processes.

Woodall said she believes leaders have a responsibility to ensure staff are prepared for the technological shifts reshaping the modern workplace.

“AI is a way women can get ahead,” she said. “It gives us knowledge at our fingertips when we need it. When you have that access to information and insight, you walk into conversations with more confidence and authority.”

The two-day programme was structured around practical exercises rather than theoretical discussion. On the first day, employees were taught how to prompt and interact with a range of leading AI tools including Gemini, Claude and Midjourney, learning how to apply them to marketing, product development, customer engagement and operational tasks.

The second day focused on experimentation and innovation. Staff were divided into 25 teams and tasked with developing AI-powered applications that could potentially enhance different areas of the business. The teams presented their ideas to senior management, with the winning group receiving a prize voucher for Selfridges.

Woodall said the initiative reflects a broader strategy to embed AI more deeply within the company’s operations as it expands internationally.

Trinny London, which reported annual turnover of around £70 million and EBITDA of approximately £4 million in 2025, has grown rapidly in recent years and opened 20 physical retail locations during 2025. The brand is now combining physical retail growth with digital innovation, including the use of predictive AI technology to personalise customer experiences.

The company has begun implementing Dynamic Yield across its online platforms, enabling website content to adapt automatically to individual users. The system analyses browsing patterns and purchasing behaviour to tailor product recommendations and marketing messages in real time.

Woodall believes this technology will help maintain customer loyalty in an industry where trends shift rapidly and brands must constantly engage consumers.

“Beauty is incredibly trend-driven,” she said. “Understanding your customer and being able to serve them the right message at the right moment is critical. AI helps us do that in a way that is far more precise.”

The company is also using AI-powered translation and localisation tools to expand into new markets without the heavy costs traditionally associated with international content production.

By automating translation workflows and adapting marketing content to local audiences, the technology allows the brand to scale its digital presence across regions including Europe, Australia and the United States.

Beyond the operational benefits, Woodall sees AI as an opportunity to address broader gender gaps in the technology sector.

Women remain underrepresented in many areas of AI development and digital leadership, yet are increasingly expected to work with AI systems in a wide range of industries. Woodall believes gaining practical experience with these tools could help women strengthen their professional confidence and competitiveness.

“There’s an opportunity here like never before,” she said. “If women learn how to use these technologies well, they can leap forward.”

The training initiative forms part of a wider effort by Woodall to support female entrepreneurship and professional development. Earlier this year she hosted a networking and mentoring event at Beaverbrook Estate, bringing together around 60 female founders and influencers for workshops on confidence building, business growth, nutrition and AI.

Woodall said she remains passionate about helping other women navigate the challenges of building businesses and careers.

“I don’t have time for any woman who doesn’t support another woman,” she said. “We have to help each other. Seeing women change how they feel about themselves is incredibly powerful.”

The former What Not to Wear presenter returned to television last year when she appeared as a guest investor on Dragons’ Den, where she jointly invested £50,000 with Deborah Meaden in sustainable cleaning brand Seep.

Although she enjoyed the experience, Woodall said she prefers mentoring entrepreneurs outside the pressure of television.

Her longer-term ambition is to establish Trinny London as the leading premium beauty brand for women over 40, a demographic she believes remains underserved in the global cosmetics industry.

“We’ve gone through a lot in life by the time we reach 40,” she said. “We know more about what we want, and what we don’t.”

By combining technology, personalisation and a focus on older consumers, Woodall believes the company is positioning itself for long-term growth in an increasingly competitive beauty market.
