Researchers have discovered a way to control the direction of electron spin in a cobalt-iron alloy, influencing its magnetic properties. The result could have implications for more powerful and energy-efficient materials for information storage.

Scientists have produced a new, less invasive platform that uses nanomaterials and may help heal damage in patients who had a heart attack by turning the body's inflammatory response into a signal to heal, rather than a means of scarring the heart.

Ovarian cancer is usually diagnosed only after it has reached an advanced stage, and most patients undergo surgery to remove as many of these tumors as possible. But because some tumors are so small and widespread, it is difficult to eradicate all of them. Researchers at the Massachusetts Institute of Technology have now developed a way to improve the accuracy of this surgery and remove tumors as small as 0.3 millimeters — smaller than a poppy seed — during surgery in mice.

Researchers have found a way to make synthetic hydrogels act like muscles by putting them through a vigorous workout. After being mechanically trained in a water bath, the hydrogels became pliant, soft, and resistant to breakdown.

For years, researchers have been trying to find ways to grow an optimal nanowire, using crystals with perfectly aligned layers all along the wire. Now, researchers have found that a defect that occurs in the growth process causes the layers of crystals to rotate along an axis as they form. This defect creates twists that give these nanowires advantages, particularly in electronics and light emission.
