Poor protein utilization contributes to neurodegeneration

Neurodegeneration can occur more quickly if nerve cells lack retromer proteins, which are responsible for breaking down toxic tau protein. This conclusion was reached by scientists who observed genetically modified fruit flies that produced human tau protein in 39 neurons of the eye. Tau protein itself already caused the death of nerve cells, and the… Continue reading Poor protein utilization contributes to neurodegeneration

Scientists disprove stereotype of lazy cannabis users

The positive effect persisted even after adjusting for several factors, such as childhood environment. The study was published in Psychological Science. Developed cognitive skills can influence academic and professional achievements, as well as health.… Continue reading Playing music in childhood has been linked to long-term improvements in cognitive abilities.

Insulin pump restores brain structure in diabetic teenagers

Researchers from the United States have found out how different methods of insulin administration affect brain development in adolescents with type 1 diabetes. Typically, this disease causes changes in the structure of the brain and leads to a decrease in cognitive abilities.

Plant milk is inferior to cow milk in terms of micronutrient content

Chemical experts from the US Food and Drug Administration (FDA) analyzed 85 milk replacers from eight different plants and found that most of them were low in phosphorus, magnesium, zinc and selenium – micronutrients of which cow's milk is an important source. The exception was drinks made from legumes – in some of these minerals… Continue reading Plant milk is inferior to cow milk in terms of micronutrient content

Scientists have grown another batch of artificial mouse embryos

Embryologists again raised mouse embryos outside the mother's body. Recently, a group of Israeli scientists conducted a similar experiment and raised baby mice to the eighth day of development. Now the British have obtained approximately the same result – and at the same time verified that the Israeli embryo culture system ex utero works. The… Continue reading Scientists have grown another batch of artificial mouse embryos

Chinese scientists have deprived mice of a chromosome. And then another one

It turned out that if the chromosomes are not very large, then it is easy to glue them together and get a mouse with an odd number of chromosomes. Such animals can grow up healthy and fertile… Continue reading Chinese scientists have deprived mice of a chromosome. And then another one
