What came first in the origin of life?
A study carried out by three European researchers contradicts the 'metabolism first' hypothesis in the origin of life.
[ + ]The DNA transistor
In an effort to build a nanoscale DNA sequencer, IBM scientists are drilling nano-sized holes in computer-like chips and passing DNA strands through them in order to read the information contained within their genetic code.
[ + ]Monitoring protein-tissue interactions in real time
Ridgeview Instruments AB’s LigandTracer Grey facilitates kinetic measurements on living cells by enabling researchers to follow protein-cell interactions in real time.
[ + ]Miniaturised analysis of complex samples
The goal of a ‘lab-on-a-chip’ - an integrated, miniaturised laboratory analysis system - is sample in, answer out. However, researchers wanting to use these microfluidic devices to analyse complex solutions containing particulates or other contaminating materials often find that the first part of the process isn’t so easy.
[ + ]Poo power and disease diagnosis
Researchers have taken high-tech gas sensors normally used to test components for premium cars and applied the same techniques to human blood, human urine and even cow dung samples. The results could lead to a new high-tech medical tool that could provide a fast diagnosis for some of the most difficult gastrointestinal illnesses and metabolic diseases.
[ + ]Vitamin C aids in producing induced pluripotent stem cells
Finding may aid in the development of regenerative medicines and produciton of iPSCs. [ + ]
Ancient koalas had booming voices
A study of the ancestors to modern koalas shows they had a different diet but could produce 'bellowing' calls. [ + ]
Microwave-assisted extraction
Extracting compounds from various samples using traditional methods involves some give and take.
[ + ]Magnetic Curie valve
Senior Scientist Christian Bahl and Development Engineer Dan Eriksen from Risø DTU have invented a three-way valve that controls the flow through a magnetic material which is attracted by an external magnet when the liquid reaches a certain temperature. The design is promising and the group is now looking for a partner in the industry who would like to join them in this work.
[ + ]Analysing high-resolution microscopy images
Automated microscopy enables the acquisition of high-resolution images at rates of one image per second and total numbers in the millions. These high rates pose a new challenge in cell biology: how to analyse the vast amounts of resulting data in a reasonable time frame?
[ + ]Researchers turn mobile phones into fluorescent microscopes
Researchers at the University of California, Berkeley, are proving that a camera phone can capture far more than photos of people or pets at play. They have now developed a mobile phone microscope, or CellScope, that not only takes colour images of malaria parasites, but of tuberculosis bacteria labelled with fluorescent markers.
[ + ]RNA isolation within specific cells
A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.
[ + ]Producing multiple, steady-state chemical gradients
The masterpieces that spring from the talents of Rembrandt, Van Gogh and other artists often begin with the creation of a gradient of colours on a palette. In a similar manner, researchers at the National Institute of Standards and Technology (NIST) have created an innovative device called the ‘microfluidic palette’, which can be used to produce multiple, steady-state chemical gradients.
