Engineered Bacteria Can Store Memories of Chemical Exposure

New research from MIT reveals that engineered E. coli can store long-term memories of chemical exposure and other events in their DNA. MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for applications […]

Research Shows Weight Influenced by Microbes in the Gut

New research from King’s College London and Cornell University reveals that genetic makeup influences whether people are fat or thin by shaping which types of microbes thrive in our body, paving the way for personalized probiotic therapies that are optimized to reduce the risk of obesity-related diseases based on an individual’s genetic make-up. By studying […]

Scientists Come Together to Reveal Cancer’s Strategies

In a new study, a group of scientists detail how they fused the power of statistical physics and artificial intelligence into a mathematical toolkit that can turn cancer-mutation data into multidimensional models that show how specific mutations alter the social networks of proteins in cells. While this may sound like the setup to some late-night […]

Study Reveals Embryos Receive Parent Specific Layers of Information

New research from San Francisco State University sheds light on the multilayered process of how a sperm and egg pass along information needed for successful reproduction, revealing that embryos receive parent-specific layers of information. The information that interprets the genetic code in a new embryo differs depending on whether it comes from the father or […]

Research Reveals Coffee Drinking Habits Shaped by Genetic Variations

A study by the international Coffee and Caffeine Genetics Consortium looked at DNA samples and data sets from the coffee-drinking habits of 120,000 people of European and African-American ancestry, providing insight on why caffeine affects people differently, and how these effects influence coffee-drinking behavior. An international research team has found six new genes underlying our […]

Salk Institute Discovers an On Off Switch for Aging Cells

Researchers at the Salk Institute for Biological Studies have discovered an on-and-off “switch” in cells that may hold the key to healthy aging. In our bodies, newly divided cells constantly replenish lungs, skin, liver and other organs. However, most human cells cannot divide indefinitely–with each division, a cellular timekeeper at the ends of chromosomes shortens. […]

New Diagnostic Method Identifies Genetic Diseases

A team of scientists has developed a test procedure that significantly increases the prospect of identifying genetic diseases quickly and reliably based on analyses of genes and symptoms. People with genetic diseases often have to embark on an odyssey from one doctor to the next. Fewer than half of all patients who are suspected of […]

Researchers Discover that a Doppler Effect Influences Segmentation

New research from the Max Planck Institute shows that the rhythm of segmentation is influenced by a Doppler effect that arises from gene expression waves occurring in a shortening embryonic tissue. Many animals exhibit segmental patterns that manifest themselves during development. One classical example is the sequential and rhythmic formation the segmental precursors of the […]

Scientists Engineer First Living Organism that Transmits Added Letters in DNA Alphabet

A newly published study details how researchers at The Scripps Research Institute were able to create the first living organism with an expanded genetic alphabet. Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA “letters,” or bases, not found in nature. The cells of […]

MIT Researchers Reverse a Liver Disorder in Mice

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]

Experts to Consider How Genetic Research Can Help People Colonize Other Planets

A recently held symposium by the HMS Department of Genetics asked experts to consider how genetic research can help people colonize other planets. If you haven’t thought about reworking the human genome so people can colonize other planets, don’t worry. Plenty of people are on it. Scientists of many stripes have been figuring out what […]

Deleting a Single Gene Reduces Fat Mass and Extends Lifespan of Mice by 20 Percent

Researchers discover that mice without the FAT10 gene have an elevated metabolic rate, burn fat as fuel, exhibit reduced glucose and insulin levels, and age more slowly than normal mice. By deleting a single gene, researchers at Yale University were able to dramatically reduce fat mass in mice while expanding their lifespan by 20%. The […]

Yale Researchers Identify a Key Link between Tumors and Healthy Tissue

Researchers from the Yale School of Medicine have discovered a key link between tumors and healthy tissue, revealing a potential mechanism used by cancer cells to recruit healthy cells to promote tumor growth. The delicate balance between development of normal tissue and tumors depends in part upon a key molecular switch within cells, Yale School […]
