Physicists record "lifetime" of graphene qubits
First measurement of its kind could provide stepping stone to practical quantum computing. Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit - meaning how long it can maintain a special state that allows it to represent two logical states simultaneously.

Team invents method to shrink objects to the nanoscale
Team invents method to shrink objects to the nanoscale
It's not quite the Ant-Man suit, but the system produces 3-D structures one thousandth the size of the originals. MIT researchers have invented a way to fabricate nanoscale 3-D objects of nearly any shape. They can also pattern the objects with a variety of useful materials, including metals, quantum dots, and DNA.

For a longer battery life: Pushing lithium ion batteries to the next performance level
For a longer battery life: Pushing lithium ion batteries to the next performance level
Conventional lithium ion batteries, such as those widely used in smartphones and notebooks, have reached performance limits. Materials chemist Freddy Kleitz from the Faculty of Chemistry of the University of Vienna and international scientists have developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries.

Sun-soaking device turns water into superheated steam
Sun-soaking device turns water into superheated steam
High-temperature steam might be used in remote regions to cook, clean, or sterilize medical equipment. MIT engineers have built a device that soaks up enough heat from the sun to boil water and produce "superheated" steam hotter than 100 degrees Celsius, without any expensive optics. On a sunny day, the structure can passively pump out steam hot enough to sterilize medical equipment, as well as to use in cooking and cleaning.

Answering the mystery of what atoms do when liquids and gases meet
Answering the mystery of what atoms do when liquids and gases meet
How atoms arrange themselves at the smallest scale was thought to follow a 'drum-skin' rule, but mathematicians have now found a simpler solution. Atomic arrangements in different materials can provide a lot of information about the properties of materials, and what the potential is for altering what they can be used for.

Two-dimensional materials skip the energy barrier by growing one row at a time
Two-dimensional materials skip the energy barrier by growing one row at a time
A new collaborative study led by a research team at the Department of Energy's Pacific Northwest National Laboratory , University of California, Los Angeles and the University of Washington could provide engineers new design rules for creating microelectronics, membranes and tissues, and open up better production methods for new materials.

Molecular insights into spider silk
Molecular insights into spider silk
Spider silk belongs to the toughest fibres in nature and has astounding properties. Scientists from the University of Würzburg discovered new molecular details of self-assembly of a spider silk fibre protein. They are lightweight, almost invisible, highly extensible and strong, and of course biodegradable: the threads spiders use to build their webs.

Technique inspired by dolphin chirps could improve tests of soft materials
Technique inspired by dolphin chirps could improve tests of soft materials
Method can be used to quickly characterize any soft, rapidly changing substance, such as clotting blood or drying cement. If you leave the putty in a small glass, it will eventually spread out like a liquid. If you pull it slowly, it will thin and droop like viscous taffy. And if you quickly yank on it, the Silly Putty will snap like a brittle, solid bar.

Switching identities: Revolutionary insulator-like material also conducts electricity
For News Media THIS NEWS IS EMBARGOED BY THE JOURNAL SCIENCE UNTIL 2 P.M. EST, NOV. 29, 2018 × University of Wisconsin-Madison researchers have made a material that can transition from an electricity-transmitting metal to a nonconducting insulating material without changing its atomic structure.

What happens when materials take tiny hits
What happens when materials take tiny hits
High-speed camera shows incoming particles cause damage by briefly melting surfaces as they strike. When tiny particles strike a metal surface at high speed - for example, as coatings being sprayed or as micrometeorites pummeling a space station - the moment of impact happens so fast that the details of process haven't been clearly understood, until now.

Sugar supplement slows tumour growth and can improve cancer treatment
Mannose sugar, a nutritional supplement, can both slow tumour growth and enhance the effects of chemotherapy in mice with multiple types of cancer. This lab study is a step towards understanding how mannose could be used to help treat cancer. The results of the study today (Wednesday). Tumours use more glucose than normal, healthy tissues.

Modified virus used to kill cancer cells
Scientists have equipped a virus that kills carcinoma cells with a protein so it can also target and kill adjacent cells that are tricked into shielding the cancer from the immune system. It is the first time that cancer-associated fibroblasts within solid tumours - healthy cells that are tricked into protecting the cancer from the immune system and supplying it with growth factors and nutrients - have been specifically targeted in this way.

Medication you can wear
Medication you can wear
Drug-releasing textiles could, for instance, be used to treat skin wounds. Empa researchers are currently developing polymer fibers that can be equipped with drugs. The smart fibers recognize the need for therapy all by themselves and dose the active ingredients with precision and accuracy. For the «Self Care Materials» project, fibers are produced from biodegradable polymers using various processes.
