These schematics show the printing of water in oil using a nanoparticle supersoap. Gold nanoparticles in the water combine with polymer ligands in the oil to form an elastic film (nanoparticle supersoap) at the interface, locking the structure in place. Credit: Berkeley Lab

Reconfigurable material could be used for liquid electronics and chemical synthesis, among other applications. Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to print 3D structures composed entirely of liquids. Using a modified 3D printer, they injected threads of water into silicone oil – sculpting tubes made of one liquid within another liquid.

They envision their all-liquid material could be used to construct liquid electronics that power flexible,...

Researchers at Trinity College Dublin may have discovered a way to switch off inflammation(Credit: Ugreen/Depositphotos)

Scientists have discovered a new metabolic process in the body that can switch off inflammation. They have discovered that ‘itaconate’ – a molecule derived from glucose – acts as a powerful off-switch for macrophages, which are the cells in the immune system that lie at the heart of many inflammatory diseases including arthritis, inflammatory bowel disease and heart disease...

A research team led by Monica Bettencourt Dias, from Instituto Gulbenkian de Ciencia (IGC, Portugal), discovered important features of cancer cells that may help clinicians fighting cancer. The researchers observed that the number and size of tiny structures that exist inside cells, called centrioles, are increased in the most aggressive sub-types of cancer. This study will be published in Nature Communications* on the 28th of March.

Cancer is a very diverse disease with some tumours being more aggressive and more resistant to chemotherapy than others...

Pieces of flexible, rechargeable yarn batteries can be connected in series to power electroluminescent panel displays. Credit: American Chemical Society

When someone thinks about knitting, they usually don’t conjure up an image of sweaters and scarves made of yarn that can power watches and lights. But that’s just what one group is reporting in ACS Nano. They have developed a rechargeable yarn battery that is waterproof and flexible. It also can be cut into pieces and still work.

Most people are familiar with smartwatches, but for wearable electronics to progress, scientists will need to overcome the challenge of creating a device that is deformable, durable, versatile and wearable while still holding and maintaining a charge...
