Scientists Discover That the Genes for Learning and Memory Are 650 Million Years Old

Posted by in categories: biotech/medical, chemistry, genetics

A team of scientists led by researchers from the University of Leicester has determined that genes responsible for learning, memory, aggression, and other complex behaviors emerged approximately 650 million years ago.

The research spearheaded by Dr. Roberto Feuda, of the Neurogenetic group within the Department of Genetics and Genome Biology, in collaboration with colleagues from the University of Leicester and the University of Fribourg (Switzerland), has recently been published in the journal Nature Communications.

<em>Nature Communications</em> is a peer-reviewed, open-access, multidisciplinary, scientific journal published by Nature Portfolio. It covers the natural sciences, including physics, biology, chemistry, medicine, and earth sciences. It began publishing in 2010 and has editorial offices in London, Berlin, New York City, and Shanghai.

Google DeepMind’s new AI tool can predict genetic diseases

Posted by in categories: biotech/medical, genetics, robotics/AI

DeepMind has released a catalog of 71 million possible variants that can cause diseases.

Genetic mutations are changes to our DNA sequence. This happens when cells make copies of themselves during cell division. Mutation is the ultimate source of human genetic variation and has evolutionary and disease genetics implications. A mutation affecting our genes might give birth to a genetic disorder. But just because you have a mutation doesn’t mean it will be a genetic disorder.

That is why researchers at DeepMind, the artificial intelligence arm of Google, have announced that they have trained a machine learning model called AlphaMissense to classify which DNA variations in our genomes are likely to cause disease.

Researchers identify inherited gene mutation linked to esophageal cancer

Posted by in categories: biotech/medical, genetics

Studying genes in families with a propensity for certain diseases has led to many critical advances in medicine, including the discovery of statins in family members who suffered heart attacks at an early age.

Now, a team of researchers at Case Western Reserve University has identified an in a gene linked to a highly lethal cancer called (EAC).

“With this discovery, we will be able to identify early those at a high risk of developing EAC in their lifetime, and accordingly tailor screening, lifestyle and treatment strategies to prevent cancer development,” said Kishore Guda, an associate professor at the Case Western Reserve School of Medicine and member of the Case Comprehensive Cancer Center.

New Research Reveals That Butterflies and Moths Share Ancient “Blocks” of DNA

Posted by in categories: biotech/medical, genetics

New research indicates that butterflies and moths share “blocks” of DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New research offers insight about the reason mitochondria

Posted by in categories: biotech/medical, genetics

New research provides insight about the bedrock scientific principle that mitochondrial DNA -; the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body -; is exclusively passed down by the mother.

The study, a collaboration among Oregon Health & Science University and other institutions, published today in the journal Nature Genetics.

Scientists have long recognized the fact that mitochondrial DNA, or mtDNA, comes exclusively from egg cells in humans, meaning only the mother contributes the genetic code carried by thousands of mitochondria necessary for energy production in every cell in the body.
