View ArticleA little stress is good for cellular health and longevity
Northwestern University molecular bioscientists have discovered that a little stress can be good for cellular health. The findings will help researchers better understand the molecular mechanisms that...
View ArticleArthritis, autoimmune disease discovery could lead to new treatments
More than 23.5 million Americans suffer from autoimmune diseases like rheumatoid arthritis, scleroderma and lupus, in which an overzealous immune response leads to pain, inflammation, skin disorders...
View ArticleDipstick technology could revolutionise disease diagnosis
New dipstick technology that enables pathogen detection and the rapid diagnosis of human, animal and plant disease in even the most remote locations has been developed by University of Queensland...
View ArticleAll-in-one repair kit makes CRISPR gene editing more precise
For the past five years, CRISPR-Cas9 technology has revolutionized the field of gene editing due to its ease and low cost. But although this technology reliably finds and cuts the targeted stretch of...
View ArticleStem cells that generate fat tissue have circadian clock
New discoveries about the circadian-clock machinery in the precursors to fat cells may explain why shift workers are prone to metabolic diseases, such as diabetes, a Stanford study finds.
View ArticleResearchers determine how alphavirus changes into infectious state
A key step in the infectious method of a family of disease-causing viruses has been identified by an international team led by scientists from Purdue University.
View ArticleMolecular beacon signals low oxygen with ultrasound
Areas of hypoxia, or low oxygen in tissue, are hallmarks of fast-growing cancers and of blockages or narrowing in blood vessels, such as stroke or peripheral artery disease. University of Illinois...
View ArticlePlant pathologists discover unusual evolutionary transition in common bacteria
It's the "Strange Case of Dr. Jekyll and Mr. Hyde" in a nursery setting.
View ArticleChimpanzee deaths in Uganda pinned on human cold virus
In the wild, chimpanzees face any number of dire threats, ranging from poachers to predators to deforestation.
View ArticleFrom the omelette to the egg: Reversing protein aggregations
To cook an omelette, you have to scramble an egg, and like Humpty Dumpty it can never be put back together again. This is because the egg undergoes a set of physiological and chemical changes as it...
View ArticleCould deer hold clues about the link between malaria resistance and sickle cell?
Scientists have identified the genetic mutations that cause sickle cells in deer, according to new research in the journal Nature Ecology & Evolution.
View ArticleEarly disease diagnosis could be dramatically improved with new detection system
By attaching specialised molecules to the backbone of DNA, researchers have made it easier to detect rare molecules associated with early disease.
View ArticleStudy warns that snake fungal disease could be a global threat
New research suggests that a potentially fatal snake fungus found in several species in the United States and three in Europe could be global in scale. The study, published today in the journal Science...
View ArticleBreaking up (protein complexes) is hard to do, but new study shows how
A new study by University of Wisconsin-Madison researchers identified the structural basis for how tightly bound protein complexes are broken apart to become inactivated. The structure explains why the...
View ArticleStatistical test relates pathogen mutation to infectious disease progression
Nucleic acid sequencing methods, which determine the order of nucleotides in DNA fragments, are rapidly progressing. These processes yield large quantities of sequence data—some of which is...
View ArticleHow Facebook could stop a disease outbreak
Facebook accounts and telephone records can be used to pinpoint the best individuals to vaccinate to stop a disease outbreak in its tracks, researchers said Wednesday.
View ArticleScientists design bacteria to reflect 'sonar' signals for ultrasound imaging
In the 1966 science fiction film Fantastic Voyage, a submarine is shrunken down and injected into a scientist's body to repair a blood clot in his brain. While the movie may be still be fiction,...
