DNA shed from colon cancers into bloodstream successfully guides chemotherapy after surgery: Helps clarify the benefit of chemotherapy in stage II cancers
A new research study showed that circulating tumor DNA (ctDNA) — genetic material shed from tumors into the bloodstream — can identify stage II colon cancer patients who can most benefit from chemotherapy following surgery and spare other patients the need for this form of treatment. The multi-institutional, international study, led by researchers at the […]
New material can ‘capture toxic pollutants from air’
Researchers at University of Limerick, Ireland have developed a new material that has the ability to capture toxic chemicals from the air. The material is capable of capturing trace amounts of benzene, a toxic pollutant, from the air and crucially use less energy than existing materials to do so, according to the researchers. The sponge-like […]
Seashell-inspired shield protects materials in hostile environments: Environmentally friendly coating outperforms conventional materials
Word of an extraordinarily inexpensive material, lightweight enough to protect satellites against debris in the cold of outer space, cohesive enough to strengthen the walls of pressurized vessels experiencing average conditions on Earth and yet heat-resistant enough at 1,500 degrees Celsius or 2,732 degrees Fahrenheit to shield instruments against flying debris, raises the question: what […]
Templating approach stabilizes ‘ideal’ material for alternative solar cells
Researchers have developed a method to stabilise a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance. The researchers, from the University of Cambridge, used an organic molecule as a ‘template’ to guide perovskite films into the desired phase as they form. Their results are reported in the journal Science. […]
Research finds key advances towards reducing the cost of plant improvement
Crop improvement often involves the transfer of genetic material from one organism to another to produce a valuable trait. Some major examples of crops with these so-called “transgenes” include disease-resistant cotton and beta-carotene-enhanced golden rice. However, when foreign DNA is introduced into a host organism, a natural defensive response in plants is to repress or […]
Novel quantum effect discovered in naturally occurring graphene: International research team finds atomically-thin carbon generates its own magnetic field
Usually, the electrical resistance of a material depends very much on its physical dimensions and fundamental properties. Under special circumstances, however, this resistance can adopt a fixed value that is independent of the basic material properties and “quantised” (meaning that it changes in discrete steps rather than continuously). This quantisation of electrical resistance normally occurs […]

Scientists observe a new type of topological defect in chiral magnets
“Topological defects” are formed when the symmetry of a magnetic material is disrupted. Domain walls (DWs) are a type of topological defect that separates regions of different magnetic orientations. A widely studied phenomenon, the manipulation of these defects has potential applications in high-performance memory storage devices, energy processing devices, and quantum computing. Recently, the possibility […]
