Nutrigenomics: How Diet Can Reprogram Our DNA

The burgeoning field of “nutrigenomics” claims that the food we eat can alter our genetics. Dietitians, scientists and lifestyle companies have all hopped on the bandwagon.

Nutrigenomics (also known as nutritional genomics) is broadly defined as the relationship between nutrients, diet, and gene expression. The launch of the Human Genome Project in the 1990s and the subsequent mapping of human DNA sequencing ushered in the ‘era of big science’, jump-starting the field of nutrigenomics that we know today.

Research: How CRISPR Can Save Lives And End Disease

CRISPR is a technology that can be used to edit genes and, as such, will likely change the world. The essence of CRISPR is simple: it’s a way of finding a specific bit of DNA inside a cell. After that, the next step in CRISPR gene editing is usually to alter that piece of DNA.

Covid-19: mRNA Vaccines Do Not Change Your DNA

With so many myths about COVID-19 vaccines regarding their impact on our health, many people don’t know what to believe. In our fact check, find out what you need to know about the mRNA vaccines — as we expose the myths and reveal the facts.

Science: What Is CRISPR And How Does It Work?

This revolutionary gene-editing system has taken science by storm. CRISPR is the basis of a revolutionary gene editing system. One day, it could make it possible to do everything from resurrect extinct species to develop cures for chronic disease.

CRISPR is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. 

Science & Wildlife: ‘The Bird Genoscape Project’

Billions of birds migrate annually across the Western Hemisphere… but if we don’t know where they go when they leave their breeding grounds, how can we protect them? By extracting DNA from individual feathers (and borrowing cutting-edge technology from the Human Genome Project) scientists can map bird migration with greater precision than ever before. The result is the Bird Genoscape Project, and it’s revolutionizing bird conservation by connecting migratory birds – and the people who care about them – across the Americas. This work was funded by the National Geographic Society. Learn more at http://www.natgeo.org.

Top New Science Podcasts: New Skin That Grows Hair, Spontaneous RNA (Nature)

Nature PodcastThis week, Nature looks at a new method to grow hairy skin in a dish, and new research takes aim at the RNA world hypothesis.

In this episode:

00:45 Hairy Skin

Researchers may have developed a way to make skin that can grow hair in the lab, paving the way for treatment of a variety of skin disorders, and perhaps even baldness. Research Article: Lee et al.News and Views: Regenerative medicine could pave the way to treating baldness

08:56 Research Highlights

How mercury moved during the ‘Great Dying’, and the link between mobile phones and gender equality. Research Highlight: Giant eruptions belched toxic metal during the ‘Great Dying’Research Article: Rotondi et al.

11:21 Does DNA predate life?

The RNA world hypothesis posits that RNA formed spontaneously leading eventually to life. Now new research suggests that RNA and DNA formed together, before life. Research Article: Xu et al.News and Views: How DNA and RNA subunits might have formed to make the first genetic alphabet
