Beyond hunger: Food insecurity in later life linked to dementia

Researchers at the University of Michigan found that older adults who experienced food insecurity in both midlife and later life had nearly four times the risk of probable dementia. Food insecurity was concentrated among those who experienced it later in life, rather than midlife alone, suggesting a strong association between later-lif...

Study finds that cognitive decline after omicron infection is largely reversible

A 2-year multicenter cohort study found that most hospitalized survivors maintained or regained cognitive function after Omicron infection, while older and reinfected patients may face progressive decline. The study identified age, infection history, and disease severity as risk factors for progressive decline.

The 2026 vehicle emissions standard rollback is founded on faulty assumptions

The 2026 vehicle emissions standard rollback is founded on faulty assumptions, according to a recent study. The analysis hinges on incorrect valuation of fuel savings, which results in billions of dollars in benefits being removed from vehicle emissions standards. A new framework for translating consumer behavior into cost-benefit anal...

Researchers develop stepwise evaporation method to reduce contact resistance in transistors

A new stepwise evaporation method called Step-Eva has been developed to reduce contact resistance in transistors. This process enables the direct in situ growth of single-crystal metal films on semiconductors, promoting atomic diffusion and facilitating lateral domain coalescence. The resulting single-crystal metal contacts exhibit low...

SNU professor min hyuk park’s joint research team reveals how ‘oxygen vacancies’ determine memory performance

A research team tracked the crystallization process of HZO thin films in real-time, revealing that oxygen vacancies affect the material's performance. Films with fewer oxygen vacancies crystallized at lower temperatures and formed the ferroelectric phase required for information storage more favorably.

Venus’s mysterious clouds may hide an exceptionally strong light absorber

Researchers have estimated that the unknown absorber in Venus's clouds must absorb light very efficiently, occur at a high concentration, or both, with a required decadic absorption coefficient reaching approximately 1,278 cm-1 at 375 nm. This suggests that highly absorbing conjugated organic molecules could be the culprit, but the stu...

New insights into how neurosurgeon Paul Kalanithi conceptualized death while facing terminal cancer

A new study examines death-related conceptual metaphors employed by neurosurgeon Paul Kalanithi in his memoir, shedding light on how he depicted death after being diagnosed with stage IV lung cancer. The research reveals that Kalanithi predominantly conceptualizes death as a transition or movement, followed by a negative presence.

The flat side of evolution: Even when multiple evolutionary paths are equally advantageous, the choice among them is not random

When multiple evolutionary paths are equally advantageous, organisms tend to drift toward flatter regions of the evolutionary landscape, favoring traits that provide greater robustness and tolerance. This suggests that biological robustness and resilience can emerge spontaneously through evolutionary dynamics.
