Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap. Scientists have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs) -- a major step toward making spray-on solar cells easy and cheap to manufacture.

One of the oldest and most widely used antibiotics, penicillin, attacks enzymes that build the bacterial cell wall. Researchers have now shown that penicillin and its variants also set in motion a toxic malfunctioning of the cell's wall-building machinery, dooming the cell to a futile cycle of building and then immediately destroying that wall.

By assessing the impacts of a range of non-steroidal anti-inflammatory drugs, research has shown that the growth of edible crops can be affected by these chemicals -- even at the very low concentrations found in the environment. The research focused its analysis on lettuce and radish plants and tested the effects of several commonly prescribed drugs, including diclofenac and ibuprofen. These drugs are among the most common and widely used group of pharmaceuticals, with more than 30 million prescribed across the world every day.

Rule-applying neurons work better under the influence of the happy hormone, researchers have found. The chemical messenger dopamine – otherwise known as the happiness hormone – is important not only for motivation and motor skills. It seems it can also help neurons with difficult cognitive tasks, they report.

Injections of a new drug may partially relieve paralyzing spinal cord injuries, based on indications from a study in rats. Every year, tens of thousands of people are paralyzed by spinal cord injuries. The injuries crush and sever the long axons of spinal cord nerve cells, blocking communication between the brain and the body and resulting in paralysis below the injury. On a hunch, researchers came up with the idea of designing a drug that would help axons regenerate without having to touch the healing spinal cord, as current treatments may require. The results, they say, are "amazing."
