Cell biologists identify new organelle present in mammalian cells made of rings of DNA
Researchers at ETH Zurich recently identified a previously unknown compartment in mammalian cells. They have named it the exclusome. It is made up of DNA rings known as plasmids. The researchers have published details of their discovery in the journa.....»»
Protein signaling pathway provides insights into cell migration and cancer metastasis
The innate immune response is the body's first line of defense against infection, and a successful immune defense takes a village: a combination of physical barriers, chemical attacks, and an army of specialized white blood cells. But maintaining and.....»»
GPT-4-based AI agents show promise for detecting antimicrobial resistance
Researchers at the University of Zurich (UZH) have used artificial intelligence (AI) to help identify antibiotic-resistant bacteria. The team led by Adrian Egli, UZH professor at the Institute of Medical Microbiology, is the first to investigate how.....»»
How can policymakers and scientists speed up progress to achieve Sustainable Development Goals?
IIASA researchers helped to identify three focus areas at the intersection of science and policy, which could foster transformative action to accelerate the achievement of the Sustainable Development Goals (SDGs). Their priorities include exploiting.....»»
DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»

Unique "barcodes" for molecules could help expedite medical advancements
Barcodes are commonly used to track items like groceries or clothing, but University of Central Florida researchers have developed a special "barcode" to identify much smaller objects: molecules......»»
Microtubule formation mechanism sheds light on how cells build their internal skeleton
Inside every cell, a network of tiny filaments, called the microtubule cytoskeleton, helps maintain the cell's shape, allows it to divide, and transports vital materials from one part of the cell to another. The filaments that form this network, term.....»»
Airborne DNA tech transforms endangered wildlife monitoring
University of Queensland researchers have created new tools that could change how conservation experts monitor and protect some of Australia's most endangered species......»»
Is the physics of red blood cells in bats a key to "artificial hibernation" for humans?
The mechanical properties of red blood cells (erythrocytes) at various temperatures could play an important role in mammals' ability to hibernate. This is the outcome of a study that compared the thermomechanical properties of erythrocytes in two spe.....»»
Scientists discover "selfish DNA" crucial for early human development
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found......»»
EV battery companies use AI to identify defects
Detecting defects is the most prevalent use of AI in EV batteries for now, but companies are considering how it could help with battery performance later......»»
