Scientists from the US, UK, and Uruguay analyzed data from 378,932 people aged 40 to 69 to see how those who are genetically ‘programmed’ to nap regularly fared cognitively […]
Zhang, one of the leading scientists in the groundbreaking field of genetic editing, had reached out two days prior to discuss a new company he was working on. Akin Akinc was scouring his email spam box last summer, looking for a missing message, when he stumbled across an unexpected email from a quite recognizable name: Feng Zhang.
Genetic testing provides patients with a diagnosis for their illness, helps patients and family members to understand risks of developing new diseases, and can be used to support clinical trial advancement. What are the benefits and limitations to using genetic testing? It is important to consider the type of testing performed (e.g.,

Team of Japanese and European scientists identify a novel genetic mitochondrial disorder by analyzing DNA samples from three distinct families Credit: Fujita Health University DNA ligase proteins, which facilitate the formation of bonds between separate strands of DNA, play critical roles in the replication and maintenance of DNA.
Credit: Mark Milburn/Atlantic Scuba Red algae that grow in Cornwall’s Fal Estuary are genetically unique, new research shows. University of Exeter scientists studied the population genetics of Phymatolithon calcareum, a coralline red algal species that forms maerl beds in shallow coastal seas from Portugal to Norway.
For two decades, scientists have been comparing every person's full set of DNA they study to a template that relies mostly on genetic material from one man affectionately known as "the guy from Buffalo."
Scientists at the National Institutes of Health have identified new genetic risk factors for two types of non-Alzheimer's dementia. These findings were published in Cell Genomics and detail how researchers identified large-scale DNA changes, known as structural variants, by analyzing thousands of DNA samples.
One reason is a person’s genetic proclivity to abuse substances. […]. CHAPEL HILL, NC – Have you ever wondered why one person can smoke cigarettes for a year and easily quit, while another person will become addicted for life? Why can’t some people help themselves from abusing alcohol and others can take it or leave it?
Forward genetics pinpoints gene linked to ASD involving severe speech impairment and opens door to search for more mutations, future treatments Credit: Photo taken by Brian Coats for UT Southwestern Medical Center DALLAS – Dec.
Scientists have identified more than 1,500 genetic differences between migratory and non-migratory hoverflies. Credit: Will Hawkes Scientists have identified more than 1,500 genetic differences between migratory and non-migratory hoverflies.
But after Cheung herself developed a genetic condition so rare it doesn’t have an official name, causing her to start losing her vision, HHMI decided to stop funding her.
Tissue collection at NOAA Fisheries lab helps reveal genetic distinction Credit: Mansur/WCR Bangladesh New genetic analysis and years of painstaking research has revealed that one of the world’s most endangered marine mammals is actually two species rather than one, as scientists had long assumed.
LA JOLLA, CA—New research shows how genetic variations linked to severe cases of COVID-19 affect our immune cells. Credit: La Jolla Institute for Immunology LA JOLLA, CA—New research shows how genetic variations linked to severe cases of COVID-19 affect our immune cells.
There’s a new kid on the block among companies using artificial intelligence in drug discovery, after 1910 Genetics launched today with $26 million in financing. 1910 Genetics is named after the year in which sickle cell disease (SCD) was first discovered in the US by James Herrick.
Scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have removed a major roadblock to better understanding of mpox (formerly, monkeypox).
Credit: UPMC PITTSBURGH, May 7, 2021 – In a paper published today in Nature Communications, an international group of collaborators led by researchers at UPMC Children’s Hospital of Pittsburgh have identified a genetic cause of a rare neurological disorder marked by developmental delay and loss of coordination, or ataxia.
In our cells, the language of DNA is written, making each of us unique. A tandem repeat occurs in DNA when a pattern of one or more nucleotides—the basic structural unit of DNA coded in the base of chemicals cytosine (C), adenine (A), guanine (G) and thymine (T)—is repeated multiple times in tandem.
Ben Hargreaves finds that the vast amount of genetic data that exists today could help provide a faster, more targeted way of developing new drug candidates. The logical extension to this kind of approach is treating individual patients, with their individual genetic makeup.
