A new genetic analysis suggests that the strains of influenza circulating in the United States can migrate to the rest of the world.
A mysterious swallowing disorder bears similarities to a disease that afflicts parrots and other exotic birds.
A genome-wide search reveals a genetic survival pathway that is switched on in many of the most aggressive glioblastomas.
A unique analysis of environmental contributors to type 2 diabetes has confirmed a link between several pollutants and the disease, while also pointing toward a form of vitamin E as a possible risk factor.
A groundbreaking comparison of human and Neandertal genomes reveals astonishingly few differences in the DNA that codes for proteins.
Scientists have new clues about what makes some people's immune systems better equipped to control HIV.
In a new study investigating just how pervasive a fruit fly’s sexual identity actually is, researchers find that most cells in flies’ bodies are identical, regardless of whether they are in a male or a female.
El parásito intestinal Giardia lamblia cambia de vestimenta casi tan frecuentemente como una modelo en una pasarela parisina, pero su amplio guardarropa de proteínas superficiales podría en realidad ser su propia perdición. Parásitos Giardia diseñados para que expresen todas sus proteínas de superficie se comportaron como vacunas que podrían ayudar a prevenir o a atenuar futuras infecciones intestinales.
A Giardia parasite engineered to express its extensive wardrobe of surface proteins worked as a vaccine that could help prevent or mitigate future intestinal infections.
By switching off a single gene, researchers have created mice that behave much like people with obsessive-compulsive disorder. The animal model could help scientists design new therapies for the debilitating condition.
Some bacteria take over cells by interfering with an important process called SUMOylation, which helps cells respond to stress.
On May 26, Egnor will give a free public lecture titled, "Whistling in the Dark: What Can Mouse Vocalizations Tell Us about the Brain?"
Scientists have uncovered thousands of DNA segments that were missing from the reference sequence of the human genome.
A molecule best known for fighting off cellular clutter is now recognized as an important defender against another cellular threat: viruses.
New research provides details of how genetic mismanagement by RNA can lead to a human disease—in this case, breast cancer.
New research suggests that training to do a new task causes groups of brain cells to “learn” how to work together more efficiently.
A new discovery shows how wing spots evolved in a species of polka-dotted fruit fly, and underscores the concept that evolution likes to tinker with existing genetic machinery.
Kaelin is one of five scientists honored with the 2010 Canada Gairdner International Award in recognition of their contributions to medical science.
New research reveals how genetic and environmental factors influence an organ that has not traditionally taken much of the blame for diabetes and cardiovascular disease.
Researchers have identified key cells involved in zebrafish heart regeneration and begun to decipher the instructions the cells use to carry out their work.
New studies of how the heart develops in mouse embryos have brought researchers closer to understanding how to induce the body’s own cells to rebuild damaged arteries.
Scientists have found several new ways to kill M. tuberculosis, which could lead to the development of alternative drugs.
An ambitious survey has identified differences in the binding of master regulators called transcription factors that affect how genes are expressed in different people.
In a discovery that may one day aid law enforcement in identifying suspects, researchers have found that skin bacteria left behind on keyboards and computer mice can identify the objects’ users.
A new software package promises to greatly speed up scientists’ ability to assemble and manipulate extremely detailed microscope images.
