Recycled paper and compost could both be key tools to control plant disease

...very cheap or waste by-products. So, paper wastes fit this bill in terms of being cheap and they also hold a lot of water, which is what you need for plant growth". The suppression of plant diseases was particularly noticeable when the green and recycled paper composts were added to peat. Peat is used...

Special chip provides better picture of salmon health

How do you tell if a fish is fit and well? This is a question which has troubled farmers and biologists for years, but now scientists may have come up with the answer - using DNA chips. By studying the genes of Atlantic salmon scientists from three UK universities are developing a D...

A new target for painkillers

...lives off portions of Australia. RgIA and Vc1.1 fit like keys into lock-like alpha9alpha10 nicotinic acetylcholine receptors, which are found on nerve cells and are in the family of receptors activated by nicotine from cigarette smoking. Alpha9alpha10 nicotinic receptors are found in a variety of b...

Mysterious 'neural noise' actually primes brain for peak performance

...current Nature Neuroscience paper he found that it fit extremely well. "The cortex appears wired at its foundation to run Bayesian computations as efficiently as can be possible," says Pouget. His paper says the uncertainty of the real world is represented by this noise, and the noise itself is in a fo...

RNA map provides first comprehensive understanding of alternative splicing

The power of one: A simpler, cheaper method for cell fusion

...c channel is so small that only two to three cells fit into it," Lu said. Lu said he believes that his device may be developed to have a higher throughput than current methods. Although Lu's technology currently fuses single pairs at once, it may be expanded so that multiple devices simultaneously fus...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

... This approach is somewhat like designing a key to fit a lock by opening the lock and looking inside. The research is being done in collaboration with Charles Gilvarg from Princeton University. "He's the biochemist who characterized the lysine pathway back in the 1950s, and so he had intimate knowledg...

Math model predicts cancer behavior

...validate the model. If the experimental data don't fit the predictions from the model, either the experiments or the model need to be corrected, he said. "You go back and forth, and every time you get a new result, you correct the model, and you're a little bit closer to reality," Quaranta said. "This ...

Faster, low cost sequencing technologies needed to drive era of personalized medicine

...rchers hope to increase the number probes they can fit on a chip. "Right now, we have a mechanical printing technology that could put down billions of probes on a chip surface at very low cost," said Gu. It is estimated that a single base pair can be sequenced for every DNA probe, which means that ...

Protein averts cell suicide but might contribute to cancer

...th half-steps protruding from each. The half-steps fit together down the center to form the complete staircase. In DNA, the half-steps are known as the bases ?the ‘A's, ‘C's, ‘G's and ‘T's ?that run the length of a DNA helix. A complete step is formed by pairs of bases according to a rule: ‘A' always...

Brain works more chaotically than previously thought

...amate sometimes be so dangerous? When an epileptic fit occurs, the nerve cells "fire" very rapidly and fiercely. In this event so many impulses run through the axons that large quantities of glutamate are released all at once. "In these concentrations the neurotransmitter damages the insulating cells," s...

MIT's ocean model precisely mimics microbes' life cycles

...y, then allows the ocean to self-select those most fit for survival in any particular area. What emerged after the model completed its 10-year virtual evolution -which took four to five days on a cluster of parallel computers-is a phytoplankton community with members that are characteristic of observe...

Anti-dandruff compound may help fight epilepsy

...i explains that ZnPy has a shape that allows it to fit into the gate region of the channel protein and allow more potassium flow. “If you think of these channels as doors on the cell’s surface,?Li says, “then ZnPy made this door both easier to open and stay open longer. It’s like a tunable hinge that hel...

Technology reveals 'lock and key' proteins behind diseases

...TH works by scanning cells to reveal proteins that fit with the transporters, the only screening system sophisticated enough to work with delicate membrane proteins. Simply, if two proteins interact in iMYTH, they will stain the yeast cell blue. "Like lock and key, if two proteins interact with one anoth...
