Mimicking natural evolution in a test tube, scientists have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth. The achievement is also likely to yield a powerful tool for evolving new and useful molecules.
Two major genetic studies of autism have newly implicated dozens of genes in the disorder...
A new breakthrough could help kidney stone sufferers get an exact diagnosis and specific...
Should every newborn baby girl be genetically screened for breast-cancer risk? That isn’t...
Researchers have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children’s Hospital. Nationwide, the virus has spread rapidly in recent months.
A new study has allowed researchers to peer into unexplored regions of the genome and understand for the first time the role played by more than 250 genes key to cell growth and development.
When tissues are deprived of blood, as happens during a stroke or heart attack, the lack of oxygen can cause serious damage. A new study shows that surprisingly, a DNA-repair enzyme called Aag actually makes this damage worse.
Scientists have discovered an algae virus never before seen in the throats of healthy people that may subtly alter a range of cognitive functions including visual processing and spatial orientation in those who harbor it.
Starting Monday, millions of people who have avoided colon cancer screening can get a new home test that's noninvasive and doesn't require the icky preparation most other methods do. The test is the first to look for cancer-related DNA in stool.
A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.
Researchers have uncovered the genes that are normally activated during recovery from bacterial infection. The finding could lead to ways to jumpstart this recovery process and possibly fend off autoimmune diseases and chronic inflammatory disorders.
Using an innovative exome sequencing strategy, a team of international scientists has shown that TUBA4A, the gene encoding the Tubulin Alpha 4A protein, is associated with familial amyotrophic lateral sclerosis (ALS).
Researchers now developed a new way to model the effects of these genetic mutations in mice. The approach, based on the genome-editing technique known as CRISPR, is much faster than existing strategies, which require genetically engineering mice that carry the cancerous mutations.
A research team has sequenced the genome of a 45,000-year-old modern human male from western Siberia. A genome comparison showed that he lived close in time to when the ancestors of present-day people in Europe and eastern Asia went different ways.
Sugar-sweetened soda consumption might promote disease independently from its role in obesity, according to a new study that found drinking sugary drinks was associated with cell aging.
Researchers have found vital new evidence on how to target and reverse the effects caused by one of the most common genetic causes of Parkinson’s.
Pancreatic cancer likely takes between 10 and 20 years to develop, providing the potential for a very “broad window” of intervention if detected early, which may be possible for people who inherit a predisposition, say researchers.
Scientists discovered an immune protein with paradoxical roles: It both aids and tamps down aspects of an immune system response, according to new research.
A new form of gene therapy for boys with X-linked severe combined immunodeficiency syndrome (SCID-X1), a life-threatening condition also known as “bubble boy” disease, appears to be both effective and safe, according to new research.
How much coffee do you drink every day? One cup in the morning? Or do you gulp it all day? Scientists have long known that your DNA influences how much java you consume. Now a huge study has identified some genes that may play a role.
By sorting human fat tissue cells by their expression of a certain gene, scientists were able to retrieve a high yield of cells that showed an especially strong propensity to make bone tissue.
Scientists have taken pictures of the BRCA2 protein for the first time, showing how it works to repair damaged DNA. Mutations in the gene that encodes BRCA2 are well known for raising the risk of breast cancer and other cancers.
The largest genome-wide association study (GWAS) to date, involving more than 300 institutions and more than 250,000 subjects, roughly doubles the number of known gene regions influencing height to more than 400.
Scientists have found that an enzyme best known for its fundamental role in building proteins has a second major function: to protect DNA during times of cellular stress.
Scientists studying two genes that are mutated in an early-onset form of Parkinson’s disease have deciphered how normal versions of these genes collaborate to help rid cells of damaged mitochondria.
Researchers have identified microRNAs that may cause colon polyps from turning cancerous. The finding could help physicians provide more specialized, and earlier, treatment before colon cancer develops.
A new study found that a bias toward certain types of DNA sequences during gene conversion may be an important factor in why certain heritable diseases persist in populations around the world.
A new genetic finding suggests that some people who are prone to hostility, anxiety and depression might also be hard-wired to gain weight when exposed to chronic stress, leading to diabetes and heart disease.
Scientists have moved a step closer to improving medical science through research involving muscle manipulation of fruit flies. They discovered in the flight muscles of Drosophila a new regulator of a process called alternative splicing.
