Molecular 'hats' allow in vivo activation of disguised signaling peptides
When someone you know is wearing an unfamiliar hat, you might not recognize them. Georgia Institute of Technology researchers are using just such a disguise to sneak biomaterials containing peptide signaling ...
Researchers discover new class of stem cells
Researchers have identified a new class of lab-engineered stem cells-cells capable of transforming into nearly all forms of tissue-and have dubbed them F-class cells because they cluster together in "fuzzy-looking" ...
Origin of the Eukaryotic cell: Part I - How to train your endosymbiont
Neural 3-D compass discovered in mammalian brain
Pilots are trained to guard against vertigo: a sudden loss of the sense of vertical direction that renders them unable to tell "up" from "down" and sometimes even leads to crashes. Coming up out of a subway ...
New technique reveals immune cell motion through variety of tissues
Neutrophils, a type of white blood cell, are the immune system's all-terrain vehicles. The cells are recruited to fight infections or injury in any tissue or organ in the body despite differences in the cellular ...
Quantum world without queues could lead to better solar cells
In a recent study from Lund University in Sweden, researchers have used new technology to study extremely fast processes in solar cells. The research results form a concrete step towards more efficient solar cells.
Japanese scientist resigns over stem cell scandal
A researcher embroiled in a fabrication scandal that has rocked Japan's scientific establishment said Friday she would resign after failing to reproduce results of what was once billed as a ground-breaking study on ...
Researchers glimpse pathway of sunlight to electricity
Four pulses of laser light on nanoparticle photocells in a University of Oregon spectroscopy experiment has opened a window on how captured sunlight can be converted into electricity.
Studies show a pathway for imported proteins through cell membrane that can be hijacked by toxins
Gold nanorods target cancer cells
Using tiny gold nanorods, researchers at Swinburne University of Technology have demonstrated a potential breakthrough in cancer therapy.
EU court clears stem cell patenting
A human egg used to produce stem cells but unable to develop into a viable embryo can be patented, the European Court of Justice ruled on Thursday.
Japan lab cannot repeat ground-breaking cell finding: reports
Some of Japan's top scientists have been unable to reproduce results of what was once billed as a ground-breaking stem cell study, but which spiralled into a scandal that included a respected researcher's suicide, reports ...
Spider's web weaves way to advanced networks and displays
The next generation of light-manipulating networks may take their lead from designs inspired by spiders and leaves, according to a new report from two Boston College physicists and colleagues at South China ...
Bugs life: The nerve cells that make locusts 'gang up'
A team of biologists has identified a set of nerve cells in desert locusts that bring about 'gang-like' gregarious behaviour when they are forced into a crowd.
