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 […]

Small Worm May Help the Fight Against Alzheimers

Scientists have discovered that a substance called N-acetylglucosamine has the ability to enhance defense mechanisms against neurodegenerative diseases, clear toxic protein aggregates and extend life span. Scientists at the Max Planck Institute for Biology of Aging in Cologne have found that a naturally occurring molecule has the ability to enhance defense mechanisms against neurodegenerative diseases.

Scientists Discover that the Obesity Associated Elements within FTO Interact with IRX3

A new study shows that the IRX3 gene controls body mass and regulates body composition, and appears to be the functional obesity gene. Mutations within the gene FTO have been implicated as the strongest genetic determinant of obesity risk in humans, but the mechanism behind this link remained unknown. Now, an international team of scientists […]

Peruvian Green Velvet Tarantula

Yale researchers find new hope for safe and novel painkillers from the venom of the Peruvian green velvet tarantula. Screening more than 100 spider toxins, Yale researchers identified a protein from the venom of the Peruvian green velvet tarantula that blunts activity in pain-transmitting neurons. The findings, reported in the March 3 issue of the […]

Gene Linking Brain Structure to Intelligence Discovered

An international team of scientists has identified a gene linking brain structure to intelligence, finding that teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere and performed less well on tests for intellectual ability. For the first time, scientists at King’s College London have identified a gene linking the […]

A Key Insight into the Biology of Embryonic Development

In a newly published study, Yale researchers detail a genetic mutation associated with congenital heart disease that disrupts a key signaling mechanism and leads to a form of heart defect associated with misalignment of major organs. The search for the cause of devastating birth defects has led Yale School of Medicine researchers to a key […]
