Rest may help reduce PTSD symptoms, UCL study finds

A new UCL study has found that a period of rest following a traumatic event can reduce the development of involuntary 'memory intrusions' in post-traumatic stress disorder (PTSD). The study suggests that increasing memory consolidation, which involves storing and contextualizing memories, may help prevent these disturbances.

Fruit flies live longer with combination drug treatment

A triple drug combination of lithium, trametinib, and rapamycin has been shown to extend the lifespan of fruit flies by 48%, a significant increase compared to previous studies. The treatment targets different cellular processes and may have potential benefits for preventing age-related diseases in humans.

Some high-cholesterol genes differ between countries

A new UCL-led study found that some genes predicting high cholesterol don't apply to people from Uganda as they do in European populations. The researchers investigated genetic variants affecting blood fat levels and found that only 10% of markers were implicated in cardiovascular risk factors among Ugandan participants.

AI uncovers new details about Old Master paintings

Researchers used a newly developed algorithm to study mixed x-ray images of the Ghent Altarpiece, separating features from the front and back of the painting's double-sided panels. The analysis improved our understanding of art masterpieces and provided new opportunities for art investigation, conservation, and presentation.

Early life on Earth limited by enzyme

A study proposes that the nitrogenase enzyme, essential for photosynthesis, blocked its own activity at 2% atmospheric oxygen levels, stabilizing oxygen levels for nearly two billion years. This negative feedback loop prevented further oxygen production and explains why oxygen levels rose to today's levels.

Filming how our immune system kills bacteria

Researchers use atomic force microscopy to track the formation of deadly holes in bacterial surfaces, discovering a bottleneck that prevents harm to human cells. The study provides insight into how the immune system kills bacteria and may guide the development of new therapies harnessing the immune system against bacterial infections.

Deep learning takes Saturn by storm

Researchers from UCL and University of Arizona developed a 'deep learning' approach called PlanetNet to detect storms on Saturn. The algorithm accurately maps the components and features in turbulent regions, revealing previously undetected atmospheric features such as ammonia ice clouds.

Dementia more preventable in Asia and Latin America

A new study found that nearly half of dementia cases in low- to middle-income countries, such as China and India, could be prevented by addressing modifiable risk factors like education, hearing loss, and obesity. Improving childhood education and health outcomes throughout life may lead to significant reductions in dementia rates.
