Chemical analysis may close the case on life on Venus

Whether or not there’s life on Venus is the subject of much debate among scientists, but a new study may close the case. Researchers at Cambridge have analyzed the Venusian atmosphere and found no sign of the chemical fingerprints microbes would be exp… Continue reading Chemical analysis may close the case on life on Venus

Alzheimer’s discovery hints at drugs to stop cells frying “like eggs”

A first-of-a-kind study has shown how Alzheimer's disease can cause brain cells to overheat

Scientists at the University of Cambridge have taken cutting-edge sensors used to measure temperature changes within cells to gain fascinating new insights into Alzheimer’s disease. The work shows how protein clumps long associated with the condition can cause heat to build up and fry brain cells “like an egg,” and more promisingly, demonstrated how drugs could be deployed to stop things from reaching harmful temperatures.

Algae energy harvester powers electronics for a year on its own

As the number of electronic devices grows, we’re going to have to get creative with our energy sources. Cambridge researchers have now demonstrated how an algae energy harvester can use sunlight to power a microprocessor for over a year without any hum… Continue reading Algae energy harvester powers electronics for a year on its own

Heat shock proteins offer clues to reversing dementia in stressed cells

A specific type of heat shock protein was found to reverse the protein misfolding associated with several neurodegenerative diseases

Researchers investigating the effects of stress on accumulations of toxic brain proteins linked with dementia have discovered a surprisingly counter-intuitive mechanism. A specific cellular stress response involving heat shock proteins has been found to reverse the build-up of these toxic proteins and future research will now look for a way to therapeutically trigger this mechanism.

More salt? Robotic chef learns to taste test as it goes

We’re starting to see robots gain footholds in the food industry in some pretty interesting ways, from droids that carry out deliveries, to systems that churn out 300 pizzas an hour to cybernetic chefs that single-handedly operate fry stations. Researc… Continue reading More salt? Robotic chef learns to taste test as it goes

Cognitive impact of severe COVID equal to 20 years of brain aging

A new study has presented the most rigorous investigation to date into the long-term cognitive impacts of severe COVID-19. The research, led by scientists from Imperial College London and the University of Cambridge, found persistent cognitive deficits… Continue reading Cognitive impact of severe COVID equal to 20 years of brain aging

Study finds seven hours of sleep to be optimal from middle-age onwards

A new study suggests that seven hours of sleep per night is best for brain health in middle and old age

We know sleep to be an essential ingredient for a healthy brain, but scientists continue to explore what a good night’s rest looks like at different stages of life, and how it can impact on our vulnerability to cognitive decline. A wide-ranging new study involving almost half a million subjects has provided compelling new insights, suggesting seven hours of sleep per night to be best for brain health during middle and old age.

Landmark DNA study finds 58 new mutations that cause cancer

A massive study has analyzed the genomes of cancer cells from more than 12,000 patients, identifying 58 new mutational signatures that offer clues to novel causes of cancer. The landmark findings offer researchers a whole trove of new resources to guid… Continue reading Landmark DNA study finds 58 new mutations that cause cancer

Social media use found to impact boys and girls at different ages

New research published in Nature Communications has found boy and girls can be vulnerable to the negative effects of social media use at different times during their adolescence. The study, from researchers at the University of Cambridge and the Univer… Continue reading Social media use found to impact boys and girls at different ages
