Children too young to know words like 'impossible' and 'improbable' nonetheless understand how possibility works, finds new work with two- and three-year-olds. The findings demonstrate that young children distinguish between improbable and impossible events, and learn significantly better after 'impossible' occurrences.

Researchers used an electrophysiological computer model of the heart's electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They discovered far less energy is needed than is currently used in state-of-the-art defibrillation techniques. The authors applied an adjoint optimization method and discovered adjusting the duration and the smooth variation in time of the voltage supplied by defibrillation devices is a more efficient mechanism that reduces the energy needed to stop fibrillation by three orders of magnitude.

Researchers employed analysis tools and machine learning algorithms to identify two genes linked to rheumatoid arthritis and osteoporosis that could serve as diagnostic tools and potential targets for treatments. Drawing from a large database of genetic information, they gathered dozens of sequenced genomes from people with rheumatoid arthritis and osteoporosis to look for any similarities, using recently developed computational methods to narrow down their search. They identified genes ATXN2L and MMP14 as significantly associated with the progression of both rheumatoid arthritis and osteoporosis.

Scientists have long suspected the keto diet might be able to calm an overactive immune system and help some people with diseases like multiple sclerosis. Now, they have reason to believe it could be true. Scientists have discovered that the diet makes the gut and its microbes produce two factors that attenuated symptoms of MS in mice.
