BOISE, Idaho — Shares of Micron Technology Inc. climbed more than 2% on Thursday after the memory chipmaker unveiled plans for a $10 billion research initiative focused on artificial intelligence technologies, underscoring investor confidence in sustained demand for high-bandwidth memory amid the ongoing AI infrastructure buildout.

The stock rose about $21 to trade near $958 in afternoon trading on the Nasdaq, recovering ground after recent volatility in the semiconductor sector. The move followed Micron’s announcement of Micron Research Labs, a new U.S.-based innovation hub headquartered in Boise and backed by a planned $10 billion investment over the next decade. The facility will concentrate on critical memory technologies, advanced memory and compute architectures, packaging, and future semiconductor manufacturing.

“The decisions we make today will determine who leads the AI economy of tomorrow, and America’s AI future will be built on American-made memory,” said Sanjay Mehrotra, chairman, president and chief executive of Micron. “With a planned $10 billion investment in Micron Research Labs, we are looking around the corner to the memory and compute systems the future will demand, bringing together the best minds across academia, government, startups and industry. This builds on the more than $250 billion we have separately committed to manufacturing and R&D across the United States, because as the only U.S.-based manufacturer of memory, we have long believed in the future that AI is now making real.”

The lab is described as the first dedicated memory research hub of its kind in the United States. It will feature a flagship campus in Boise designed to support hundreds of researchers, along with university collaborations, global satellite labs and partnerships across the semiconductor ecosystem. Construction is expected to begin in 2027. The investment is separate from Micron’s broader U.S. manufacturing expansions, including new fabs in Boise and New York.

Mehrotra reinforced the strategic shift in memory’s role during a subsequent interview. “Memory is no longer a component in a system, memory is the strategic infrastructure for AI,” he said. “It is no longer a commodity, it is a high value. Without memory, you cannot make AI smarter, cannot make it faster, you cannot scale up AI. AI is driving a whole hierarchy of memory requirements from HBM to DRAM to SSDs.”

Micron has emerged as one of the clearest beneficiaries of the AI boom. In its fiscal third quarter ended in late May, the company reported revenue of $41.46 billion, more than quadrupling from $9.3 billion a year earlier and well above analyst estimates. Adjusted earnings reached $25.11 per share, also exceeding expectations. Data center revenue alone exceeded $25 billion in the quarter, implying an annualized run rate above $100 billion. Gross margins expanded sharply, reflecting higher pricing power in a tight supply environment.

Looking ahead, Micron guided for roughly $50 billion in revenue in the current quarter. The company has signed 16 strategic customer agreements, many with multi-year terms running into 2030, locking in substantial future volume at minimum pricing. Fourteen of those agreements carry a cumulative revenue potential of about $100 billion. Management has collected significant customer deposits and said demand for high-bandwidth memory continues to exceed available supply. HBM4 revenue has already surpassed $1 billion, with ramps proceeding faster than previous generations.

Industry conditions remain constrained. Micron and peers have repeatedly indicated that memory supply is unlikely to catch up with AI-driven demand before 2028 at the earliest, and possibly later. High-bandwidth memory production consumes substantial wafer capacity that would otherwise go to conventional DRAM used in servers, PCs and smartphones, amplifying shortages across the broader market. Prices for both specialized and commodity memory have risen accordingly.

Micron’s market capitalization has crossed the $1 trillion threshold at points during 2026 as the stock delivered gains of several hundred percent over the past year. The company remains the sole U.S.-based producer of leading-edge DRAM and NAND, a position that has drawn support from federal policy aimed at strengthening domestic semiconductor supply chains. Recent comments from administration officials have emphasized reducing reliance on foreign memory sources.

Scott DeBoer, Micron’s executive vice president and chief technology and products officer, framed the research initiative as an extension of the company’s long history in Boise. “For nearly 50 years, from four people in a Boise basement to America’s memory leader, Micron has pushed the boundaries of what memory can do,” he said. “Micron Research Labs gives that legacy a dedicated home for long-horizon innovation, the kind of research that sits upstream of every product we build.”

Investors have weighed the strong near-term fundamentals against the traditional cyclicality of the memory business. After earlier peaks above $1,200 earlier in the summer, the shares experienced pullbacks amid broader technology-sector rotations and valuation concerns. Analysts remain largely constructive, citing multi-year visibility from the strategic customer agreements and the structural nature of AI demand. Some have raised long-term earnings estimates significantly, pointing to potential operating leverage as capacity comes online and pricing remains elevated.

The Boise announcement also aligns with larger capital commitments already under way. Micron has outlined more than $200 billion in planned U.S. manufacturing and research spending, including leading-edge fabs expected to begin producing DRAM in Idaho in 2027. Those projects are positioned to support both HBM and conventional memory output as demand continues to broaden beyond training clusters into inference, edge devices and enterprise applications.

Market participants will watch closely for updates on yield ramps, additional customer agreements and any signs that supply constraints are easing. For now, the combination of robust financial results, multi-year contracts and a fresh commitment to long-horizon research has reinforced Micron’s position at the center of the AI memory story. Shares remain sensitive to shifts in hyperscaler spending plans and competitive capacity additions from peers in South Korea and elsewhere, yet the latest investment signals management’s confidence that the current demand environment has multi-year durability.

Federal agencies are warning that hackers are actively targeting industrial control systems used across U.S. water plants, factories, energy facilities and other critical infrastructure.

The NSA, FBI, Department of Energy, EPA and Cybersecurity and Infrastructure Security Agency said Wednesday there is an “active threat” targeting Siemens S7 Series programmable logic controllers.

Siemens said Thursday that it had not detected an increased level of attacks or any previously unknown vulnerabilities affecting its industrial control systems products.

The devices are used to monitor and control industrial equipment across sectors including manufacturing, energy, water and wastewater, chemicals, food and agriculture.

A successful attack could disrupt critical operations, force facilities offline, damage equipment and create safety hazards, according to the advisory. Officials also warned that breaches could trigger cascading disruptions across interconnected systems.

The government said hackers are increasingly using artificial intelligence to make such attacks easier, dramatically reducing the expertise and time needed to develop tools capable of exploiting industrial systems.

According to the advisory, attackers are scanning the internet for exposed or poorly protected Siemens controllers and using AI-generated tools to help gain access to them.

Federal agencies said the activity appears aimed in part at studying targeted systems and developing the ability to disrupt operations in the future.

Such attacks could affect production, public services and supply chains, while also causing equipment damage or prolonged downtime.

Officials also warned that some operators may not realize their systems are exposed, particularly when outside vendors have remote access to industrial equipment.

The warning comes amid a recent wave of cyberattacks against local water systems that cybersecurity experts suspect may have links to Iran, though federal officials have not formally attributed those incidents to Tehran.

CISA warned July 30 of a significant increase in attacks targeting programmable logic controllers. Days earlier, the agency said Iranian-affiliated hackers had been exploiting industrial equipment made by Siemens, Rockwell Automation and Schneider Electric.

Concerns intensified after Minnesota became the first state to report a wave of at least 30 cyber incidents involving local water systems on July 26 and July 27.

Federal officials have stopped short of blaming Iran for those attacks. President Donald Trump said July 31 that he did not believe Tehran was responsible and instead criticized Minnesota over the incidents.

The latest warning underscores the vulnerability of operational technology — systems that control physical equipment rather than simply store corporate data.

HACKERS ARE GOING AFTER WHATEVER THEY CAN ATTACK TO MAKE NEWS, RUBRIK CEO SAYS

Unlike conventional cyberattacks focused on stealing information, attacks on industrial control systems can have direct physical and economic consequences, potentially interrupting utilities, shutting down production or damaging costly equipment.

Siemens told FOX Business that it is aware of the alert and is coordinating with CISA.

“Siemens will provide updates around this issue to potentially affected customers through our ProductCERT team,” a company spokesperson said. “At this point in time, we have not identified increased attack levels or unknown vulnerabilities in Siemens ICS products.”

Welsh Fire co-chair Mark Rhydderch-Roberts dissects The Hundred season, and urges doubters to give it a go

After a frenetic 27 days and a gripping and sold out Finals Day last Sunday at Lord’s, the 2026 Hundred tournament has concluded.

Despite the best efforts of some to focus on a marginal decline in total attendances, this season has seen an incredibly competitive and successful tournament with many of the best men’s and women’s players in the world involved.

Many games have gone down to the last few balls and there has been a noticeable increase in intensity on all levels. Teams, owners and fans are desperate to win.

Despite a crowded and competitive sporting calendar over the summer, including a football World Cup, The Hundred has recorded its third best campaign in terms of ticket sales in the last six years, with around 550.000 sold, with three new record attendances.

Probably more significantly, given the fact that media revenues drive operating performance and valuations, the growth in the average broadcast audience on Sky Sports and the BBC was 7.5 per cent. Furthermore, this has been the most viewed and engaged season ever digitally for The Hundred with a 36 per cent rise in engagement and 55 per cent growth in views on social channels.

Objectively, this is a very creditable performance given the context of a major reset of The Hundred, the first year of co-ownership with new international investors, and a number of rebrands taking place. This year was never going to be straightforward. Taking on co-ownership or new ownership meant new teams, new brands and commercial challenges with a short pre-season lead time.

Hundred plan

The Hundred was designed from the outset to bring cricket to new audiences, especially children and families. As in previous years, the demographic of fans attending The Hundred has continued to grow strongly and is sharply differentiated to many competitor sports – 2026 saw 22 per cent of tickets go to under-16s, 40 per cent to families and 28 per cent for women.

At Welsh Fire – following the 50/50 joint venture agreement between Glamorgan County Cricket Club and Sanjay Govil – we have had record breaking attendances for both the men’s and women’s games in Wales, with ticket sales up almost 10 per cent year-on-year. Nearly half of ticket buyers were new to Sophia Gardens home, Wales’ Test-standard arena. Welsh Fire was the only Hundred franchise to increase its ticket sales in percentage terms year on year.

The Hundred achieved a valuation of just under £1bn after the franchise sale last year and provided an immediate and much needed cash injection in excess of £550m into English and Welsh cricket at all levels, with 10 per cent of proceeds earmarked for the recreational game.

The double headers have turbo-charged the growth of the women’s game and the introduction of international investors has not only brought capital but a global dimension and commercial expertise to the sport in Britain. Other sports, including rugby union, which traditionally has had a similar audience profile in size and demographic will only look on enviously.

The sports asset class has seen sustained and rapid uplifts in valuations as the sector has become investment grade for many institutional investors, as well as for private equity companies and high-net-worth individuals. This trend has been confirmed with the recently announced sale of the LA Lakers for £9bn, the highest price ever paid for a sports team and £2bn more than it sold for 14 months ago. In the UK, Jeff Bezos is part of a consortium that is buying 38 per cent of Liverpool FC which values the club at £5.5bn, 18 times more than the £300m that John Henry’s Fenway Sports Group paid for the club in 2010. It would be logical to assume that The Hundred franchise valuations have already benefited from this macro trend.

International growth

Growth in cricket and international franchise valuations has, and will continue to be, driven by India which accounts for over 70 cents in every dollar generated by cricket globally. The overall business and brand valuation of the Indian Premier League is in excess of $20bn and it ranks as the second richest sports league in the world by per-match value, second only to the NFL. Media revenues also remain critically important for valuations – around 95 per cent of the ECB’s total revenues are derived from this source. Independent forecasts give global cricket media revenues around ten years of strong future growth. This is in contrast to several other sports, including Football, where they have plateaued or are in decline.

Realistically, the valuations enjoyed by the IPL, where two franchises in the Rajasthan Royals and Royal Challengers Bengaluru were recently sold for $1.65bn and $1.8bn respectively, are some way ahead of where The Hundred teams are right now. However, I believe that there is a strong case that over the next few years that The Hundred can take its place as the second most important and valuable short format global cricket league.

In a nation where sporting life has long been defined by rugby and football, Welsh Fire is an elite team and brand the nation can get behind. Demand and interest has surged not only in south Wales and along the M4 corridor but also from the south west of England.

Our chief commercial officer Ed Rice says that “Wales needed more than a franchise cricket name, it needed a team that felt Welsh, and belonged to Wales”, adding that a “deep local understanding has driven every decision, and the commercial results speak for themselves”.

A case for Cardiff

Cardiff is the UK’s premier event city after London, and this summer has seen an extraordinary array of major music and sports events. Against that backdrop, Welsh Fire cut through by offering something distinctive: elite sport combined with a genuinely entertaining day out at a competitive price point. We embraced a challenging fixture list, which included a Monday and two Wednesday fixtures, and invested in it. The iconic Welsh rock band Feeder performed in between matches on the Monday evening and we recorded a total attendance in excess of 10K.

The challenge for The Hundred and for Welsh Fire will be to build from here. A breakthrough first “Hundred reset” year does not remove the economic headwinds facing sport, nor does it make audience growth automatic. It gives us something valuable for all of us to work with; a larger database, a more engaged fan base, stronger awareness and proof that The Hundred can prosper and grow.

This is why The Hundred season should be celebrated, and we remain in the early days of something real and significant in global cricket. At Welsh Fire, we now have the opportunity to invest further in growth, technology, content, partnerships and community engagement, while maintaining a laser focus on a team built for Wales.

We also have learned much from our co-owner, and will continue to build and develop the significant operational and commercial synergies that exist between Welsh Fire and Sanjay’s Washington Freedom MLC franchise.

I wish The Hundred doubters could have been at our sold-out Saturday fixture against MI London a few weeks ago. The atmosphere at Sophia Gardens as the fans chanted “Wales, Wales” was unique, the excitement and engagement of the crowd total. There will be many more days like these to come.

Sony’s PlayStation Network experienced a fresh wave of user-reported access problems Thursday, according to outage-tracking service Downdetector, adding to what has become an unusually persistent pattern of disruptions affecting the gaming service throughout 2026.

Downdetector posted on its official account on the social platform X that “user reports indicate problems with Playstation Network since 12:55 PM EDT,” tagging the post with the hashtag #PlaystationNetworkDown and directing affected users to its outage-tracking page for further updates. The post had drawn nearly 1,200 views within a short period after being published.

Thursday’s reported disruption extends a notably rocky year for PSN reliability. According to a running tally maintained by Tech Insider, PlayStation Network went down six separate times over just over four months earlier this year, most recently during a roughly five-hour, 23-minute worldwide disruption affecting PS5, PS4 and web services on July 24. That outage, one of the most severe of the year, drew significant attention given that Sony has offered no public explanation for the cause behind any of the six confirmed incidents logged so far in 2026.

Coverage of the July 24 outage from Push Square documented the incident unfolding in real time over several hours that afternoon and evening. Sony’s own service status page described the network as “experiencing issues” for an extended period, with the company specifically flagging difficulty accessing the PlayStation Store even as other functions gradually returned. According to Push Square’s live updates, Downdetector showed a substantial spike in user reports across the United States during the outage, which only began meaningfully easing several hours after the initial disruption began. By that evening, Sony confirmed PSN was “up and running” again, though the outlet noted some isolated issues could still linger even after the broader network had stabilized.

The timing of PSN’s repeated 2026 outages has drawn particular scrutiny given a separate decision by Sony earlier this year to raise PlayStation Plus subscription prices. According to Tech Insider, Sony increased PlayStation Plus pricing across all tiers effective May 20, 2026, citing “ongoing market conditions,” with the Monthly Essential tier rising from $9.99 to $10.99 and Monthly Premium climbing from $17.99 to $19.99, while annual subscription pricing remained unchanged in that particular round of increases. A network disruption followed less than 24 hours after that price hike took effect, logging 176 reports within the first 24 hours on outage-tracking service IsDown, according to Tech Insider’s reporting, with the outlet noting that, as of its most recent update, no public explanation had been offered for that specific incident either. The recurring outages carry added significance for subscribers specifically because online multiplayer functionality on both PS5 and PS4 requires at least a PlayStation Plus Essential subscription, meaning each PSN disruption this year has directly blocked a feature that subscribers are now paying more to access following the May price increase.

Sony has faced additional headwinds beyond the outage pattern and pricing changes in recent months. According to Tech Insider, the company also settled a $7.85 million antitrust case related to older digital purchases, and is separately planning to retire the “PlayStation Network” branding by September 2026 in favor of a visual rebrand, while keeping user accounts, friends lists and underlying services otherwise unchanged. The outlet emphasized that none of these developments, including the repeated outages, the pricing changes, the antitrust settlement and the branding shift, are legally connected to one another, even as their overlapping timing has drawn continued attention from gaming media and PlayStation’s user base.

The stakes surrounding PSN reliability have also grown given Sony’s broader strategic direction for its console business. According to Game Informer, PlayStation announced earlier this year that it will cease production of physical game discs for new titles beginning in January 2028, a shift that will leave players increasingly dependent on digital distribution and, by extension, on PSN’s continued reliability. Game Informer noted that during PSN outages, physical discs have historically allowed players to at least access offline-playable content stored directly on a disc, while many digital games, including some single-player titles, require an online authentication check that becomes impossible to complete when the network is down, leaving affected players locked out of games they own entirely during service disruptions.

Sony’s history with major PSN outages extends well beyond this year’s cluster of incidents. The most severe disruption in the network’s history remains the 2011 PlayStation Network outage, a 24-day incident caused by an external security intrusion that exposed personal data for 77.1 million PlayStation Network accounts and ultimately cost Sony an estimated $171 million. More recently, a major outage in February 2025 left PlayStation users worldwide unable to access online services, manage accounts or make purchases through the PlayStation Store for more than 18 hours, according to Notebookcheck’s coverage at the time, affecting popular titles including EA Sports FC and Call of Duty and disrupting scheduled online tournaments and promotional events tied to those games.

As of this report, independent monitoring service Entireweb Status had most recently characterized PlayStation Network as operating normally, based on a check conducted roughly a week prior to Thursday’s reported disruption, recording 80 user reports over a 24-hour period at that earlier point, with three of those submitted within the final hour before the check. Given the discrepancy between that earlier reading and Thursday’s fresh spike in Downdetector complaints, the scope and duration of the current disruption remained unclear as of this report, with Sony not having issued an updated public statement addressing Thursday’s specific reported issues.

Given the network’s documented pattern of repeated, unexplained outages throughout 2026, gamers experiencing difficulty accessing PSN services Thursday were likely to view the disruption as consistent with what has become an increasingly familiar, if still frustrating, feature of the platform’s reliability this year, with continued scrutiny expected regarding whether Sony will offer any public explanation for the underlying cause behind this latest incident, as it has similarly declined to do for each of the network’s prior confirmed outages so far in 2026.

The U.S. economy is currently “worse” than when former President Joe Biden departed office last year, economic and political commentator Peter Schiff asserted, warning that the nation faces the “threat” of a Democratic socialist winning the White House during the 2028 presidential election.

President Donald Trump is “unpopular because the economy is worse now than it was when Biden left office,” Schiff, chief economist and global strategist of Euro Pacific Asset Management and host of “The Peter Schiff Show” podcast, told Fox News Digital during an interview on Wednesday. 

“So Trump ran promising to fix what Biden broke,” but then “broke it more,” Schiff asserted. 

“He said that prices will come down on day one as soon as I become president,” Schiff said, adding “inflation is a bigger problem now than it was when Trump was elected.”

Fox News Digital reached out to the White House on Thursday.

TRUMP’S APPROVAL RATING PLUMMETS TO NEW LOW AHEAD OF CRITICAL MIDTERMS: ‘MORE WORK TO DO’

McCormack/Getty Images for London Blockchain Conference; Eric Lee/Getty Images)

While Republicans currently hold majorities in both chambers of Congress, Schiff said that he thinks the GOP will lose many House seats in the midterm elections this year and that they “have a real chance of losing the Senate too.”

Schiff said he expects the party to lose control of the Senate in 2028 if they haven’t lost their majority in the chamber before then and that he thinks the GOP will lose the presidency in 2028 as well. He warned that “the real threat” looming over the 2028 White House contest is the possibility of “a real Democratic socialist” getting elected as president.

Schiff, who is involved in selling precious metals through SchiffGold, made a case for people buying gold and silver. “Buy real money that will preserve its purchasing power,” he said.

He argued that investors should be “diversifying into stocks in international markets” to protect against “a weak U.S. dollar.”

Schiff said “stagflation” will “be a big problem for the U.S. economy for years to come,” warning of a “crisis” pertaining to “sovereign debt” as well as “currency.”

“But I want people to understand that this is not about a failure of capitalism. It’s about a failure to have capitalism. It’s a failure of central planning, central government, central banking. It’s big government that interfered with the free market that created the problem. And the solutions that are gonna be proposed by government to increase the size of government, to have even more regulation, to have even more taxes, they will just make all the problems worse,” Schiff said.

The U.S. national debt has surpassed $40 trillion, according to the U.S. Treasury.

“We need to rein in government. We need massive cuts to government spending, deregulation, we need free market forces,” he said.

Schiff said, “Republicans are in a predicament because doing the right thing economically is probably political suicide, which is why they won’t do it.”

People who live past age 100, and especially those who reach 110 or beyond, appear to carry a striking abundance of rare, cancer-fighting immune cells in their blood, according to new research that offers a possible clue into how so-called supercentenarians manage to avoid the illnesses that typically claim most people decades earlier.

The findings, published in the journal Cell Reports through Cell Press, focus on a rare category of T helper cells that appears to proliferate significantly as people age past roughly 100 years old, expanding and adapting over time in ways researchers say reflect an active, evolving immune response rather than simple biological decline.

The human immune system relies on T helper cells, also known as CD4 cells, as a core component of adaptive immunity. Among the many subtypes of CD4 cells, a particularly rare variant known as cytotoxic CD4 T cells, or CD4 CTLs, typically occurs only infrequently in the human body. Unlike most helper cells, which coordinate immune responses, CD4 CTLs function more like dedicated killers, patrolling the body to identify and destroy infected, damaged or cancerous cells before they can cause further harm.

According to the study, these normally scarce CD4 CTLs become increasingly common as people age into their 90s and beyond, with the effect growing even more pronounced among centenarians and supercentenarians specifically. Researchers analyzed blood samples from 28 Japanese participants across different age brackets, a group the study’s authors acknowledge represents a small sample size drawn from a single country and therefore may not necessarily be representative of the broader global population.

Among eight participants in their 70s, 80s and 90s, the median proportion of CD4 CTLs in their blood samples measured 4%. That figure rose sharply among the study’s 10 centenarian participants, where the median proportion reached 9.6%. Among supercentenarians specifically, individuals who have lived past 110, the median proportion climbed even further, to 17.6%. Notably, even within this small sample, researchers identified at least one outlier: a participant who had not yet turned 100 but nonetheless showed the highest proportion of these cells recorded anywhere in the study. Researchers also noted that the CD4 CTLs identified in older participants showed no signs of cellular exhaustion, remaining biologically active despite the advanced age of the individuals carrying them.

Kosuke Hashimoto, an immunologist at the University of Osaka in Japan and one of the study’s researchers, said the findings challenge a common assumption about how the immune system changes with age. “Immune aging is not simply a process of decline,” Hashimoto said. “The selective expansion of certain T cells suggests that, even in extreme old age, the immune system may continue to adapt to age-related challenges.”

To better understand how these cells develop, the research team examined specific proteins present on the surface of the cells. They found that CD4 CTLs appear to emerge through a process in which helper cells sequentially lose two particular surface proteins, first CD27 and later CD28, a transformation that effectively converts the cells from their original helper function into their rarer, cytotoxic killer form.

The researchers also observed a hallmark of active immune defense within the samples: clonal expansion, a process in which killer T cells replicate themselves in response to a perceived threat, effectively building a targeted immune “army” against a specific antigen. According to the study’s findings, roughly 33% of the CD4 CTLs identified in older participants’ blood were, on average, clones descended from a single original cell. In one particularly striking centenarian sample, researchers found that approximately half of that individual’s total CD4 CTL population consisted of copies derived from the very same original cell.

The study’s authors interpret this pattern as evidence that the human body faces a growing burden of immune threats as it ages, and that an expanding population of CD4 CTLs may be helping certain individuals, at least among the Japanese supercentenarians studied, successfully manage those threats well beyond the age at which most people succumb to illness. Describing the underlying immune activity captured in the research, the study’s authors wrote that “these cells exhibit stepwise differentiation and cytokine plasticity, suggesting adaptive responses to persistent antigens during healthy aging.”

Hashimoto connected the broader biological backdrop driving this immune adaptation to the natural accumulation of cellular abnormalities that occurs with advancing age. “As we age, abnormal cells, including senescent and cancerous cells, become more common,” Hashimoto said. “Our findings suggest that immune adaptation to these changes may contribute to exceptional longevity.”

The new findings add to a growing body of research examining the biological underpinnings of extreme human longevity, an area of study that has drawn increasing scientific attention as global populations of centenarians and supercentenarians, though still exceedingly rare, have continued to grow in recent decades. Related research has previously identified other biological markers associated with slower aging among centenarians, including a set of 37 distinct proteins found in the blood of long-lived individuals that researchers have linked to a slower overall pace of biological aging, according to prior coverage of separate longevity research.

Given the modest size and geographic limitation of the current study’s sample, the researchers have cautioned that further work involving larger and more diverse populations will likely be necessary to confirm whether the abundance of CD4 CTLs observed among Japanese supercentenarians represents a broader, universal biological feature of extreme human longevity, or whether it may instead reflect genetic, environmental or lifestyle factors more specific to the population studied. Even so, the findings offer researchers a promising new avenue for understanding how, at a cellular level, a small subset of humans manage to avoid succumbing to cancer and other age-related illnesses well beyond the point at which most people’s immune systems begin to falter.

JONESBORO, ARK. — Contract manufacturer SANY Nutrition Group has opened a food production plant in Jonesboro that will turn out a range of better-for-you and comfort snacks and other products for the private label and branded channels in North America.

In a more than $30 million investment, SANY Nutrition acquired and remodeled the former Butterball manufacturing plant in Jonesboro, according to the Arkansas Economic Development Commission (AEDC). Operations at the facility, which can make up to 400 million bars and bites annually, are underway. The site is expected to create over 150 new jobs in three years.

SANY Nutrition’s manufacturing capabilities cover six product categories: better-for-you snacks (high protein, reduced sugar, functional, plant-based and nutritionally balanced); sports nutrition (performance bars/bites and functional snacks to support energy, endurance, recovery and active living); indulgence-focused comfort snacks (with rich textures, layered fillings, chocolate coatings and bold flavors); frozen plant-based snacks (made with real fruit and vegetables such as pumpkin, beetroot and sweet potato and then protein-enriched and coated in sugar-free chocolate); baked foods and pastries (sweet, savory, better-for-you and functional bakery products, from cinnamon rolls and filled pastries to protein-rich, individually wrapped items); and pet nutrition (treats and functional snacks formulated to meet the needs of pets).

The Jonesboro plant also can produce a range of food ingredients, inclusions, fillings, coatings, bases and semi-finished solutions for food manufacturers, retailers, foodservice operators and brand partners, the AEDC said.

The Jonesboro facility has the capacity to produce up to 400 million bars and bites annually.

“SANY Nutrition Group is an innovative protein snack manufacturing company that combines the speed and fearless mindset of a startup with the technology, expertise and scale of a global organization,” said Angela Pernsteiner, an investor in Jonesboro-based SANY Nutrition. “Through tailor-made formulation, premium ingredients, state-of-the-art equipment and European-American process excellence, we transform bold ideas into distinctive, shelf-ready products — in weeks, not years.”

With the Jonesboro facility, SANY Nutrition also brings an integrated platform that encompasses consumer insight, concept development, formulation, design, regulatory support, advanced manufacturing, shelf-ready packaging, warehousing and distribution, the AEDC added.

“SANY Nutrition Group is choosing to invest its capital to grow in Jonesboro, Ark., building a new manufacturing facility and creating 150 new jobs,” said Clint O’Neal, executive director of the AEDC. “Jonesboro has become a food manufacturing hub thanks to its abundant natural resources, low costs, and the strategic vision of its leadership. This has led to investments from companies like SANY.”
