Plastic Exposure During Pregnancy Hinders Brain Development

Perinatal Exposure to Phthalates Results in Lower Number of Neurons and Synapses in the Medial Prefrontal Cortex

Adult rats that had been exposed before birth and during nursing to a mixture of chemicals found in a wide range of consumer products have a smaller medial prefrontal cortex (mPFC) and perform worse on an attention-switching task than rats not exposed to the chemicals early in life. These findings, published in JNeurosci, demonstrate a long-term influence of endocrine-disrupting compounds on brain development. Kougias et al., JNeurosci (2018)



How Socio-economic Migration Affects DNA Patterns in the UK


A major new study reveals how socio-economic migration within the UK has affected the geographic distribution of human DNA linked to traits such as education levels and health.


Strategy Could Help Treat Behavioral Abnormalities Linked to Autism


Researchers report in Nature Medicine a potential new treatment strategy for autism spectrum disorder – for which many cases are linked to mutated PTEN. Now, using Pten-deficient mice, researchers discover that a previously unexplored pathway goes “awry” in the brain, and by “rescuing” this pathway, it is possible to reverse behavioral and neurophysiological abnormalities.


Real Texture for Lab-grown Meat


Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have grown rabbit and cow muscles cells on edible gelatin scaffolds that mimic the texture and consistency of meat, demonstrating that realistic meat products may eventually be produced without the need to raise and slaughter animals.
