They have been a scourge for thousands of years, responsible for the spread of lethal diseases such as malaria and dengue fever, and, much less urgently, a threat to barbecues around the globe. What if there was a way to render humans invisible to mosquitoes?
For decades, the mouse has been a mainstay for researchers studying human diseases because the two species share many of the same genes. But now, a comprehensive analysis of the inner workings of the DNA in humans and mice has uncovered some striking differences in the way their genes are controlled.
Researchers have developed new insight into a rare but deadly brain infection. Read more...
Scientists report a new method for establishing whether chemical compounds are safe for human use without in vivo testing. Read more...
Researchers designed a therapeutic molecule that both targets the acidic microenvironments of tumors and penetrates cells to deliver a therapeutic cargo. Read more...
New study shows that in the core of the brain’s reward system are specific neurons that are active both with use of and withdrawal from nicotine. Read more...
A new study shows that calorie-reduced diets stop the normal rise and fall in activity levels of close to 900 different genes linked to aging and memory formation in the brain. Read more...
Scientists at The University of Manchester are attempting to map the genes of an endangered British sea creature to aid a captive breeding program. Read more...
A new study from geneticists has found that the DNA replication plan— including where the origin points are and in what order DNA segments get copied- varies from person to person.
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 such as sensors for environmental and medical monitoring.
Damaged messenger RNA can jam cellular machines that make protein. The failure to clear the jams and chew up bad messengers is associated with neurodegenerative diseases such as Alzheimer's.
Scientists have discovered gene mutations that give people naturally lower cholesterol levels and cut their risk of heart disease in half. That discovery may have a big implication for a blockbuster heart drug.
With the help of mouse models, induced pluripotent stem cells (iPSCs) and the “tooth fairy,” researchers have implicated a new gene in idiopathic or non-syndromic autism.
When munched by grazing animals (or mauled by scientists in the lab), some herbaceous plants overcompensate– producing more plant matter and becoming more fertile than they otherwise would. Scientists say they now know how these plants accomplish this feat of regeneration.
People who carry a particular type of gene have natural resistance against typhoid fever according to new research. The study is the first large-scale, unbiased search for human genes that affect a person’s risk of typhoid.
Researchers have developed the first gene network to be operated via brainwaves. Depending on the user’s thoughts, it can produce various amounts of a desired molecule.
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome reveals some surprising clues.
Scientists have uncovered how the massive DNA molecules that appear in some tumors are formed like Frankenstein’s monster, stitched together from other parts of the genome.
“Berlin Patient” Timothy Brown was cured of HIV after he received stem cells from a naturally immune patient. His story inspired two companies to try and recreate that natural immunity in HIV patients using stem cells and cutting-edge gene-editing. Now Harvard has joined the race.
More than a decade after the completion of Human Genome Project, precision medicine has struggled with what it known as the "last mile." Despite major leaps in the field, the technical work needed to integrate genomic information into the day-to-day practice of medicine has lagged far behind.
Scientists have sequenced the mitochondrial genome in glaucoma patients to help further understanding into the genetic basis for the disease. Glaucoma is a major cause of irreversible blindness, affecting more than 60 million people worldwide.
A research team has used whole genome sequencing to identify a new genetic cause of a severe, rare and complex form of epilepsy that becomes evident in early childhood and can lead to early death.
Bacteria in colonies don’t reproduce sexually and are genetically identical, yet they can prepare in advance for changing environmental conditions. Researchers have shown that bacteria carry out this strategy by producing cells with differing amounts of specific proteins that govern their response to chemical signals.
The human populations now predominant in Eurasia and East Asia probably split between 36,200 and 45,000 years ago, according to a study released Thursday.
Ebola and Marburg are 16 to 23 million years old, not thousands of years old as once thought, according to a new study. The research also indicates that while Ebola and Marburg diverged from each other millions of years ago.
