• Following the catastrophic dam collapse at Vale’s Corrego de Feijao mine in Brumadinho, the Global Industry Standard of Tailings Management (GISTM) was developed to enhance the safety and strengthen the governance of tailings facilities across the globe.

• The candidate aims are to design, manufacture, and study advanced photonic integrated waveguides and microresonators based on a thin-film periodically poled lithium tantalate nanowaveguide platform. The main focus will be the development of advanced nanofabrication technologies for optical waveguide fabrication with low optical loss and high optical nonlinearity to demonstrate breakthroughs in the efficiency and bandwidth of nonlinear optical amplification and frequency conversion. The research will be performed at the Department of Electronic Systems, NTNU, and supported by scientific partners in Switzerland and China.

• John McAdam had originally created the method of using crushed stone road surfaces, with the name of tarmacadam derived from him. But he was not able to create a surface where stones stuck together. Mr Hooley took what he saw and spent a year working on a method to replicate it elsewhere. By 1902 he had patented a process of adding slag to heated tar and breaking stones within the mixture to create a smooth, sold surface. He made Radcliffe Road in Nottingham the world’s first Tarmac road, covering five miles of it with his mixture.

• Holton, R. A. et al. First total synthesis of taxol .2. Completion of the C-Ring and D-Ring. J. Am. Chem. Soc. 116, 1599–1600 (1994).

• The physical properties and crystal structures of most tellurate materials were only discovered during the last two decades, but they have tantalizing properties. For example, they respond to light in a way very similar to current solar materials.

• What happens when you expose tellurite glass to femtosecond laser light? That's the question that Gözden Torun at the Galatea Lab at Ecole Polytechnique Federale de Lausanne, in collaboration with Tokyo Tech scientists, aimed to answer in her thesis work when she made the discovery that may one day turn windows into single material light-harvesting and sensing devices. The results are published in Physical Review Applied.

• The Spaniard then talked about his tenure at Madrid itself, and the regret he has from the two seasons at the club.

• Cancellus heatherae, female holotype, shield length – 4 mm: (A) habitus, dorsal; (B) habitus, right side; (C) habitus, ventral; (D) sixth tergite and telson, dorsal. Image credit: Felder & Lemaitre, doi: 10.11646/zootaxa.4890.4.10.

• The approach to investigating where the wing formed involved reverse engineering. Using gene knockouts and a microsurgery experiment, the team found that the cells on the tergum and not the pleura, or sides, are key to wing formation. 

• Augsten R, Konigsdorffer E, Strobel J. Surgical approach in terson syndrome: vitreous and retinal findings. Eur J Ophthalmol. 2000;10:293–6.

• DHARAMSHALA, April 19: Former Tibetan political prisoner Namkyi, who escaped into exile last year shared a gripping testimonial of her suffering and persecution under Chinese occupation in Tibet, at a press briefing on Friday, at the exile Tibetan government’s compound here.

• Erupting from the page and screen with a masterful use of colour and form, Esther's illustrations blend the nuanced textural drawing techniques of watercolours and ink with the precision and perfection of modern digital mediums. This powerful combination captures the essence of her subjects as well as the emotional and social narratives that underpin daily experiences.

• The collection was a masterclass in textural alchemy. The black laminated jersey of the distorted drape dresses reflected the light, imparting a liquid-like quality that contrasted sharply with the solid structure of the tailored coats with T-bar chain backs. McGirr's use of black wool mohair accented with smashed jet stone embroidery and complemented by natural shearling vests exemplified his skillful hand — a blend of tailored discipline and tactile opulence.

• Ukrainian drones have begun using gravity thermite munitions to destroy equipment and fortifications.

• Schiavone says Jami flew to Cincinnati from New York with thermite -- a powder used in fireworks -- and sparklers.

• In a landmark achievement for physics, the United Kingdom and Ireland-based Institute of Physics this month published a first-of-its-kind monograph on phototransferred thermoluminescence authored by Rhodes University’s head of Physics, Professor Makaiko Chithambo.

• Doped with carbon and magnesium, the material becomes thermoluminescent in response to UV radiation

• Her senior thesis was on the light-emission properties of thermoluminescent chips, used as radiation measuring devices. She doesn’t remember how anyone at Reed obtained the mysterious TLDs, but once they were in her hands (so to speak), she was able to gamma-irradiate them in the reactor, and then use a newly acquired Tektronix rapid-scan spectrophotometer to look at the heated chips’ light emissions. 

• PM1K+, PM3K+, and PM6K+ water-cooled, thermopile sensors incorporate a BB+ broadband coating to measure power of continuous-wave or modulated lasers up to 1 kW, 3 kW, and 6 kW in output power, respectively, within the spectral range of 190 nm to 11 µm. A 50-mm-diameter active area measures fiber lasers, CO2, lasers and high-power industrial laser sources.

• Among his creations are a set of military compasses (sectors) that were simple enough for artillery crews and surveyors to use. Together with instrument maker Marc’Antonio Mazzoleni, he would produce 100 such compasses with an instruction manual for each. Galileo also offered training courses on how to use them that he himself would teach, for roughly twice the cost of one such instrument. He also created the thermoscope and thermometer — the latter of which used the thermal expansion of air to push water up in an attached tube.
