Research reveals evolution of cells' signaling networks in diverse organisms
(Phys.org) —Cells use protein-signaling networks to process information from their surroundings and respond to constantly changing environments. This includes information about the presence or absence of ...
Potent, puzzling and (now less) toxic: Team discovers how antifungal drug works
Scientists have solved a decades-old medical mystery – and in the process have found a potentially less toxic way to fight invasive fungal infections, which kill about 1.5 million people a year. The researchers ...
How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
Amoeba study puts bite on dysentery
An amoeba parasite that causes potentially fatal dysentery in poor countries wreaks its havoc by eating intestinal cells alive, scientists reported on Wednesday.
Nanotubes made from plants could allow delivery of DNA into cells, improve chemotherapy treatment
(Phys.org) —Researchers with the University of Florida's Institute of Food and Agricultural Sciences took what some would consider garbage and made a remarkable scientific tool, one that could someday help to correct genetic ...
Researchers discover ancient virus DNA remnants necessary for pluripotency in humans
Embryonic stem cells: Reprogramming in early embryos
An Oregon Health & Science University scientist has been able to make embryonic stem cells from adult mouse body cells using the cytoplasm of two-cell embryos that were in the "interphase" stage of the cell ...
Small step towards growing tissue in the lab
(Phys.org) —University of Adelaide mathematicians have devised a method for identifying how cell clusters have formed by analyzing an image of the cluster.
New DNA-editing technology spawns novel strategies for gene therapy
The University of California, Berkeley, and UC San Francisco are launching the Innovative Genomics Initiative (IGI) to lead a revolution in genetic engineering based on a new technology already generating ...
A flexible approach is needed for Australia's electronics industry
Australia's manufacturing industry could be given a welcome boost if it takes advantage of some of the latest research here and overseas to create ultra thin and flexible electronic devices.
New cell line should accelerate embryonic stem cell research
Researchers at the University of Washington have successfully created a line of human embryonic stem cells that have the ability to develop into a far broader range of tissues than most existing cell lines.
Whole-genome sequencing of the elephant shark offers insights into bone disease and immunity in humans
Sequencing the genomes of vertebrates can provide scientists with valuable clues about the evolution of the human genome. By analyzing and comparing different genomes, researchers can pinpoint variations ...
Horses set to gain health benefits from stem cell advance
Horses suffering from neurological conditions similar to those that affect humans could be helped by a breakthrough from stem cell scientists.
Microgravity and radiation exposure add up to serious health risks for astronauts
Astronauts floating weightlessly in the International Space Station may appear carefree, but years of research have shown that microgravity causes changes to the human body. Spaceflight also means exposure ...
