Scientists studied a three-droplet structure that, tagged with fluorescent dye, reminds them of Dr. Seuss’ Grinch in a Santa hat. Credit: Kennedy lab We know a lot about how genes get passed from parent to child, but scientists are still unraveling how so-called epigenetic information—instructions about which genes to turn on and off—is conveyed from […]Continue Reading ...
There’s no single gene for eye colour. Credit: Shutterstock When humans’ genetic information (known as the genome) was mapped 15 years ago, it promised to change the world. Optimists anticipated an era in which all genetic diseases would be eradicated. Pessimists feared widespread genetic discrimination. Neither of these hopes and fears have been realised. The […]Continue Reading ...
Functional magnetic resonance imaging (fMRI) and other brain imaging technologies allow for the study of differences in brain activity in people diagnosed with schizophrenia. The image shows two levels of the brain, with areas that were more active in healthy controls than in schizophrenia patients shown in orange, during an fMRI study of working memory. […]Continue Reading ...
An international team, led by scientists from the School of Science at IUPUI and Erasmus MC University Medical Center Rotterdam, has developed a novel tool to accurately predict eye, hair and skin color from human biological material. The innovative high-probability and high-accuracy complete pigmentation profile webtool is available online without charge. Credit: Walsh lab in […]Continue Reading ...
Credit: CC0 Public Domain Once upon a time in Europe, pregnant women avoided rabbits to prevent their babies from being born with a “harelip.” But, that apparently isn’t the only misconception about the condition now known as cleft lip. In the May 1 issue of Cell Reports, UConn Health researchers report the popular modern belief […]Continue Reading ...
The C/EBPß-LIP gene regulator is involved in the aging process. If LIP is missing, the lifespan of mice increases and physical fitness is maintained during aging; without a calorie restriction. Credit: Kerstin Wagner / FLI Aging is a major risk factor for physical frailty and the development of age-related diseases such as cancer, cardiovascular diseases, […]Continue Reading ...
Babies with inherited intolerance of fructose face a risk of acute liver failure if they are fed certain formulas containing sucrose or fructose, pediatricians and geneticists are warning.

Many conclusions drawn from a common approach to the study of human genetics could be distorted because of a previously overlooked phenomenon, according to researchers at the Department of Genetics and Genomics Sciences at the Icahn School of Medicine at Mount Sinai and collaborators from Massachusetts General Hospital and the Broad Institute. Their conclusions and […]Continue Reading ...
Credit: CC0 Public Domain The nauseating, often debilitating, headaches affect 15-20 percent of adults in developed countries, yet they remain stubbornly hard to explain. Scientists know that migraines tend to run in families but aren’t sure exactly how. A new study published May 3 in the journal Neuron shows why some families are susceptible to […]Continue Reading ...
Acute angle closure glaucoma of the right eye (intraocular pressure was 42 in the right eye). Credit: James Heilman, MD/Wikipedia Glaucoma—the leading cause of vision loss worldwide—includes a heterogeneous group of disorders. Primary open-angle glaucoma (POAG) and exfoliation glaucoma (XFG) are linked to decreased outflow of aqueous humor, which affects intraocular pressure. A multi-institutional team […]Continue Reading ...
If Canada’s Genetic Non-Discrimination Act (GNA) is overturned by a challenge from the Province of Quebec, it will open the doors to genetic discrimination, argue authors in a commentary in CMAJ (Canadian Medical Association Journal). “The GNA is a critical law affording comprehensive protection prohibiting genetic discrimination by any individual or sector,” writes Dr. Yvonne […]Continue Reading ...
This electron microscopic image of two Epstein Barr Virus virions (viral particles) shows round capsids—protein-encased genetic material—loosely surrounded by the membrane envelope. Credit: DOI: 10.1371/journal.pbio.0030430.g001 A far-reaching study conducted by scientists at Cincinnati Children’s reports that the Epstein-Barr virus (EBV)—best known for causing mononucleosis—also increases the risks for some people of developing seven other major […]Continue Reading ...
Credit: CC0 Public Domain You are what you eat, the old saying goes. But it turns out that may be backwards. What if, in fact, you eat certain things because of who you are? Scientists have known since 2013 that a common version of the gene FGF21 makes us consume more carbohydrates. Now, for the […]Continue Reading ...
Credit: CC0 Public Domain The largest analysis to date of genetic data in amyotrophic lateral sclerosis (ALS) – the muscle-crippling neurodegenerative disease that afflicted the late astrophysicist Stephen Hawking and cut short the career of iconic Yankee baseball slugger Lou Gehrig – has identified two previously unrecognized genetic risks that are significantly associated with the […]Continue Reading ...
