Adverse childhood experiences, such as being raised in poverty, can be detrimental for cognitive development often leaving children struggling in school and trapped forever in a cycle of hardship. But a study is now suggesting a innovative (and easy) way to help.
Researchers have discovered that females with multiple sexual partners can be more fertile than those that are monogamous, and this because of an “overproduction” of sons. The study, published as a provisional article but already one of the most accessed in BCM Evolutionary Biology, helps to explain a puzzle haunting evolutionary biologist for decades: why so many females chase multiple sexual partners in a mating season, when this is costly and dangerous, and one is enough to fertilize all her eggs.
The recent discoveries that α-Synuclein(α-Syn), a central player in Parkinson´s disease (PD) brain destruction, can not only pass from one neuron to another but also exist outside neuronal cells, has led to a rethink of the disease. A study investigating α-Syn effects out of the cell has found that the protein can interfere with the normal functioning of the hippocampus, the brain area for memory and learning, what might start explaining the cognitive and memory problems seen in so many PD patients.
A team of Portuguese researchers have developed amathematical tool that can classify any region in the world according to itspattern of development into one of 5 types - each with specific characteristicsand predictable behaviours - that call for different interventions and policymeasures. The discovery, just out inNature’s Scientific Reports, representsa major step towards a new type of city planning - objective and, mostimportantly, independent of the personalvisions, interests and ever changing politics .
