The Microbiome Is Shaped By Genetic Differences In The Immune System

Differences in the genes of the immune system sculpt the assortment of bacteria that colonize the digestive system, new research[1] by scientists at the University of Chicago indicates. “When the input is standardized, you can compare mice of different genetic strains and see what these genetics do to the microbiome…Continue readingThe Microbiome Is Shaped By Genetic Differences In The Immune System

In Collecting Genetic Data, An Ethical Catch-22

In 2009, researchers collected DNA from four elderly men in Namibia, each from one of the many San indigenous communities scattered across southern Africa. A year later, analyses of the men’s DNA were published in the journal Nature — alongside that of South African human rights activist Desmond Tutu. The…Continue readingIn Collecting Genetic Data, An Ethical Catch-22

Second Gene That Makes People Sleep Less Found

A mother and daughter who share a rare genetic mutation and who routinely need just six hours of sleep a night have led to researchers taking a further step in untangling the genetic web of sleep[1]. “Before we identified the first short-sleep gene, people really weren’t thinking about sleep duration…Continue readingSecond Gene That Makes People Sleep Less Found

How Transcriptomics Is Changing How We Think About Brain Cells

Neurons, the fundamental component of the nervous system, exist in a multitude of forms and types. There may be as many as 10,000 specific types of neurons in the human brain. There is even a type of cell discovered in 2005 known as the “Jennifer Aniston neuron” that specifically responds…Continue readingHow Transcriptomics Is Changing How We Think About Brain Cells

A High-definition Map Of Liver Cells In Health And Disease

Researchers have created a high-resolution picture of the cells at work inside a key hub of metabolism — the liver — and shown how disease reprograms individual cell types. In every tissue throughout our bodies, various cell types communicate and coordinate their efforts to perform vital functions and maintain health.…Continue readingA High-definition Map Of Liver Cells In Health And Disease

Study Advances Radically New Model Of Gene Control

In recent years, MIT scientists have developed a new model for how key genes are controlled that suggests the cellular machinery that transcribes DNA into RNA forms specialized droplets called condensates. These droplets occur only at certain sites on the genome, helping to determine which genes are expressed in different…Continue readingStudy Advances Radically New Model Of Gene Control

CBD And Genetic Testing Provide Hope For ‘Intractable’ Epilepsy In Children

It can start with a vacant stare, what appear to be muscle twitches or a full-blown seizure. But no matter how it begins, any time a child is diagnosed with epilepsy is often a frightening time for families. About 470,000 children are living with epilepsy in the U.S. While there…Continue readingCBD And Genetic Testing Provide Hope For ‘Intractable’ Epilepsy In Children
