A team of plastic surgeons and material scientists has invented a synthetic soft tissue substitute that is well tolerated and encourages the growth of soft tissue and blood vessels. This new material retains its shape without being too dense, overcoming challenges with current tissue fillers that tend to be either too soft or not porous enough to let cells move in and start regrowing tissue.
Controlling the properties of ultrafast light pulses is essential for sending information through high-speed optical circuits and in probing atoms and molecules. But the standard method of pulse shaping is costly, bulky and lacks the fine control scientists increasingly need. Now researchers have developed a novel and compact method of sculpting light with nanoscale precision.

Most implantable and wearable medical devices benefit from having on-board batteries powering them, but because conventional batteries have specific internal geometries, they are not flexible. Now researchers have developed stretchable supercapacitors – devices that can hold onto electrical charge and release it as necessary – that can be pulled to eight times their original size and continue working.

Radiation kills tumors by creating oxygen free radicals that damage the tumor DNA. However, the lack of oxygen in the center of tumors blocks the production of free radicals, inhibiting radiation killing. Researchers have now designed a nanoparticle that generates radiation-induced oxygen free radicals even in the low-oxygen center of tumors, dramatically increasing the success of radiation therapy.

Engineers have made thin polymer films that conduct heat – an ability normally associated with metals. They found that the films, which are thinner than plastic wrap, conduct heat better than many metals, including steel and ceramic. These results may spur the development of polymer insulators as lightweight, flexible, and corrosion-resistant alternatives to traditional metal heat conductors.
