Possible blood test for colon cancer
Up to half of people who should be screened for colorectal cancer do not get the routine procedure. A blood test to detect colorectal cancer being developed by Stanford doctors and materials scientists could help change that. Colorectal cancer is the second leading cause of cancer deaths in the U.S. and a growing problem around the world, but not because it's a particularly difficult cancer to detect and halt.

The wood magician
The new head of Empa's Cellulose & Wood Materials lab, Gustav Nyström, has taken everyone by surprise by setting unconventional goals. However, paper batteries and nanocellulose sensors have one main objective: to help solve fundamental, socially relevant questions. When Gustav Nyström sees a tree, he sees more than just a biological marvel.

Wonder material: individual 2D phosphorene nanoribbons made for the first time
Tiny, individual, flexible ribbons of crystalline phosphorus have been made and measured an international collaboration, in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene (the phosphorus equivalent of graphene) in 2014, more than 100 theoretical studies have predicted that new and exciting and properties could emerge by producing narrow ‘ribbons' of this material.

KU Leuven engineers calculate where microplastics will end up
What is the impact of weathering processes on microplastics, and how do the particles spread across seas and oceans' Computer models developed by hydraulics engineers from KU Leuven may help to find the answers. Through rivers and wastewater, enormous amounts of minuscule plastic particles end up in our seas and oceans.

Fuel cell advance a breath of fresh air for future power alternative
A promising alternative to conventional power plants, solid oxide fuel cells use electrochemical methods that can generate power more efficiently than existing combustion-based generators. But fuel cells tend to degrade too quickly, eating up any efficiency gains through increased cost. Now, in an advance that could help lead the way toward longer-lived green energy devices, engineers at the University of Wisconsin-Madison have revealed new insights about the chemical reactions that power fuel cells.

Rotten to the core
Rotten to the core
Fungi that decompose tree trunks can conjure up real works of art in wood. In nature, however, the decay-causing fungi not only decorate the tree, but also destroy it. Empa researchers are now teaching the fungi how to draw. The result: upscale marbled wood that can be processed into design furniture or musical instruments.

AI accurately predicts useful life of batteries
AI accurately predicts useful life of batteries
In an advance that could accelerate battery development and improve manufacturing, scientists have found how to accurately predict the useful lifespan of lithium-ion batteries, used in devices from mobile phones to electric cars. If manufacturers of cell-phone batteries could tell which cells will last at least two years, then they could sell only those to phone makers and send the rest to makers of less demanding devices.

The Best Topological Conductor Yet: Spiraling Crystal Is the Key to Exotic Discovery
The Best Topological Conductor Yet: Spiraling Crystal Is the Key to Exotic Discovery
The realization of so-called topological materials - which exhibit exotic, defect-resistant properties and are expected to have applications in electronics, optics, quantum computing, and other fields - has opened up a new realm in materials discovery. Several of the hotly studied topological materials to date are known as topological insulators.

Deliberate Short Circuits and Nail Torture as a Means of Enhancing Security: Battery research
Deliberate Short Circuits and Nail Torture as a Means of Enhancing Security: Battery research
Most of the people who stroll across the Leonardo campus are unlikely to notice a narrow, single-storey building. The construction in question is about 25 metres long and five metres wide. It is adorned with red and white stripes, has a corrugated iron roof, and is surrounded by a wire mesh fence which is about 1.5 metres high.

Self-extinguishing device uses body movement to determine when workers are in danger Meghan Steele Horan Imagine a device that could stand up to even the most intense fires so that it could automatically signal others when a firefighter is immobilized on the job. UCLA researchers and colleagues at two other universities have designed the first fire-retardant, self-extinguishing motion sensor and power generator.

High-quality bespoke nanocrystals
Stanford researchers redefine what it means for low-cost semiconductors, called quantum dots, to be near-perfect and find that quantum dots meet quality standards set by more expensive alternatives. Tiny, easy-to-produce particles, called quantum dots, may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors and medical imaging tools.

Scientists Take a Deep Dive Into the Imperfect World of 2D Materials
Berkeley Lab-led team combines several nanoscale techniques to gain new insights on the effects of defects in a well-studied monolayer material Nothing is perfect, or so the saying goes, and that's not always a bad thing. In a study at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), scientists learned how nanoscale defects can enhance the properties of an ultrathin, so-called 2D material.

A self-healing composite
Researchers from EPFL's Laboratory for Processing of Advanced Composites have developed a material that can easily heal after being damaged. This cutting-edge composite could be used in aircraft, wind turbines, cars and sports equipment. When a wind turbine blade or an airplane is hit by something, the damaged part has to be either replaced or patched with resin.
