The deadly tapeworm spreading across America has reached the Pacific Northwest

7 hours 5 minutes ago
A potentially dangerous tapeworm linked to severe, cancer-like disease has now been found in the Pacific Northwest, marking its first detection in wild animals along the U.S. West Coast. Researchers discovered the parasite, Echinococcus multilocularis, in 37% of coyotes tested around Puget Sound—a surprisingly high rate for a region where it had never been reported until recently.

Beyond technical access in digital eldercare: how ethical lag shapes stratified responsiveness to institutional welfare in rural China

10 hours 37 minutes ago
CONCLUSIONS: The findings suggest that limited uptake of digital elder care is closely tied to moral legitimacy and ethical recognition. Digital care services are more likely to be accepted when perceived as a supportive extension of, rather than a replacement for, family care responsibilities. Addressing ethical lag through culturally resonant service design and trusted community mediation may help reduce inequalities in engagement and improve the effectiveness of ageing-related service...

Scientists shut down cancer DNA repair to overcome drug resistance

1 day 7 hours ago
Cancer cells often survive treatment by fixing the DNA damage that therapy is meant to cause. Researchers found that UNI418 can disrupt this repair ability, leaving cancer cells more exposed. When combined with a PARP inhibitor, it helped resistant cancer cells respond to treatment again. The findings point to a new strategy for overcoming cancer drug resistance.

A classic brain test exposed AI's biggest weakness

1 day 9 hours ago
Researchers gave top AI models a classic attention test used in psychology and found a major flaw. While the models could correctly name colors in short lists, their performance deteriorated sharply as the task became longer and more complex. Some leading systems fell from over 90% accuracy to nearly complete failure.

Scientists mapped every neural connection in a fruit fly and found a surprise

1 day 10 hours ago
A groundbreaking new connectome maps every neural connection in an adult fruit fly’s central nervous system, creating an unprecedented view of how the brain and body work together. The findings suggest that complex behaviors emerge from distributed local circuits rather than a single central controller, offering new clues about intelligence, movement, and brain function.

Cerebral hypoperfusion and the vascular-metabolic-immune-glymphatic network in Alzheimer's disease: mechanisms, diagnosis, and therapy

1 day 10 hours ago
Alzheimer's disease (AD), characterized by progressive cognitive decline, represents a major public health challenge in aging societies. Since the proposal of the amyloid cascade hypothesis, Aβ-targeted therapeutic strategies have dominated this field for over three decades. Although recent anti-Aβ antibodies have shown modest promise, their limited clinical benefits coupled with safety concerns underscore the necessity of re-evaluating the pathological mechanisms underlying AD. Cerebral...

Cerebellar aging is spatially heterogeneous and supports cognitive resilience in later life

1 day 10 hours ago
The cerebellum contains most of the brain's neurons and supports many functions, yet how it changes with age remains unclear. Here we used three brain imaging studies spanning 47,000 adults and examined how different parts of the cerebellum age and their relation to cognition. We characterized cerebellar aging using volumetry and the T1-weighted/T2-weighted ratio, and corroborated these findings with quantitative magnetic resonance imaging in an independent sample. We show a spatially...

Dual-target gene therapy in Parkinson's disease: a multicenter phase 1 trial

1 day 10 hours ago
Restoring striatal dopamine synthesis is a promising gene therapy strategy for Parkinson's disease. Previous adeno-associated virus-mediated aromatic L-amino acid decarboxylase (AADC) monotherapies remain dependent on exogenous levodopa, whereas multigene delivery is constrained by strict adeno-associated virus packaging limits. A 'dual approach' targeting the two rate-limiting enzymes, tyrosine hydroxylase (TH) and AADC, offers the potential for autonomous dopamine synthesis. We report the...

A decline in skeletal muscle NOX4 abrogates exercise-induced adaptive homeostasis and exacerbates biological aging

1 day 10 hours ago
A decline in nuclear factor erythroid 2-related factor 2 (NFE2L2)-orchestrated adaptive homeostasis and oxidative distress are thought to be key features of aging. In contracting skeletal muscle, the reactive oxygen species-producing enzyme NADPH oxidase 4 (NOX4) is a potent inducer of NFE2L2 adaptive homeostasis. Here, we report that skeletal muscle NOX4 levels decline in aged mice and humans, resulting in abrogated NFE2L2 adaptive homeostasis, increased protein oxidative damage, and decreased...
