A low-power pulsed laser has been used to weld ceramic materials together in room-temperature environments for the first time. [52] A group of researchers at the University of Illinois at Urbana-Champaign and Kyushu University has developed a way to remove ice and frost from surfaces extremely efficiently, using less than 1% of the energy and less than 0.01% of the time needed for traditional defrosting methods. [51] Light and sound waves are at the basis of energy and signal transport and fundamental to some of our most basic technologies-from cell phones to engines. [50] NUS scientists have developed a method for directional excitation of plasmons at molecular length scale with electrically driven sources. [49] Titanium oxide (TiO2) nanofibers can have various applications, such as in catalyzers and filters. [48] Today, scientists report progress in making versions of these nanoparticles that could someday give built-in night vision to humans. [47] A new piece of a difficult puzzle-the nature of memory-fell into place this week with a hint at how brain cells change structure when they learn something. [46] Researchers at the University of Alberta have found an important protein in the cells of a deadly infectious parasite, opening the door to less harmful treatment for millions of people suffering from diseases like sleeping sickness in Africa and Chagas disease in South America. [45] The remarkable ability of a small Australian sea snail to produce a colourful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical. [44] Gene editing technology is a technology that eliminates the underlying causes of and treats diseases by removing specific genesor editing genes to restore their normal function. In particular, CRISPR gene editing technology is now commonly used for immunotherapy by correcting the genes of immune cells to induce them to attack cancer cells selectively. [43]
