Samsung’s InHouse Robots Are A Chip Play, Not A Product

Samsung didn’t promote from within to lead RX’s strategy — it hired Executive Vice President Lee Dongkun, who previously directed robotics strategy at Hyundai Motor Group, the parent of Boston Dynamics, and who oversaw development of the electric Atlas humanoid and Spot quadruped during Hyundai’s push to commercialize both. That hire, paired with Samsung’s Rainbow Robotics subsidiary already commercializing the RBY1 wheeled dual-arm platform and developing HUBO bipedal prototypes, signals a company assembling deployment expertise, not just research capability. See our coverage of Unitree’s TIME cover hiding a 9% industrial deployment problem for how deployment expertise, not funding or hype, is the scarce resource across this entire sector right now.

Samsung’s in-house robots strategy also extends to components most competitors buy from third parties: the company is developing its own actuators using motor technologies adapted from home appliances, an unusual but financially logical move for a company that already runs enormous consumer-electronics manufacturing lines. Owning that layer reduces both cost and dependency on the same small set of actuator suppliers every other humanoid maker competes for.

⚠ Fiction — composite scenario, not a real event: A robotics analyst covers Samsung’s RX division purely as a Tesla and Unitree competitor, publishing a forecast comparing unit shipment targets. Two years later, Samsung has shipped fewer finished humanoids than expected — but its foundry chip revenue from robotics customers across five different manufacturers has quietly become a bigger business line than the humanoid unit itself, exactly the outcome the shipment-focused forecast never modeled.

Time-restricted eating may help retain cognitive function in older adults

Results from a small clinical trial suggest it may be possible to reduce the risk of dementia by eating during fewer hours of the day. The pilot study, which involved a weight-loss program for older women with overweight or obesity, showed modest cognitive improvements among those who limited their daily eating window instead of just reducing their calorie intake.

“Losing weight alone will ward off some of the aging-related cognitive decline, and these data suggest that there may be additional benefits if you stop eating four hours before going to sleep and reduce food intake to 8–9 hours per day, compared with the usual eating window of 12 hours per day,” said Sue Shapses, Ph.D., RD, DFASN, professor at Rutgers University and Rutgers-RWJ Medical Center and the study’s principal investigator.

Shapses’ group will present the findings at NUTRITION 2026, the flagship annual meeting of the American Society for Nutrition, held July 25–28 in National Harbor, Maryland, just outside Washington, D.C.

Embattled hedge fund Situational Awareness invests $400M in chip startup Source Foundry

Situational Awareness may have had to sell off the majority of its public portfolio last month, but the AI-focused hedge fund is still making some big bets.

This week, the fund invested $400 million into Source Foundry, a startup founded by Stanford researchers aiming to make chip manufacturing faster and cheaper, according to The Wall Street Journal. That brings its total investment in Source Foundry to $500 million.

Situational Awareness was founded by Leopold Aschenbrenner, a former OpenAI researcher in his mid-twenties who had no trading experience when he launched the fund in 2024. Early returns were reportedly strong, but the fund faced steep losses in recent months amidst the decline in AI infrastructure stocks.

Simple biological age score flags higher cognitive decline risk in older adults

A study of 4,818 middle-aged and older Chinese adults found that higher light BioAge was associated with greater risks of cognitive impairment, episodic memory decline, and reduced mental intactness. The simple measure, based on age, creatinine, glucose, and CRP, added modest predictive information but requires further validation before clinical use.

Brain activity reveals two stages of visual processing before conscious perception

Seeing feels immediate; we open our eyes and the world seems to appear as a continuous stream. But some visual illusions show that events occurring later can change how we perceive what happened earlier, suggesting that the brain may collect and combine information for a short time before producing the experience that reaches awareness.

This effect is known as “postdiction.” Here’s an example: Two colored dots appear briefly in different places, but people see only a single moving dot that changes color along the way. This means that the second dot must influence how the first is perceived, a typical example of postdiction.
