Strange Material Gets Better at Conducting Electricity The Thinner It Gets
16+ hour, 27+ min ago (299+ words) Copper is a much sought (and much stolen) metal because it powers the proliferation of data centers, electric vehicles, and energy infrastructure. Copper also forms interconnects, the wires that transfer electricity between the semiconducting transistors that form the basic building…...
Carbon Dots Emerge as a Powerful Weapon Against Superbugs and Biofilms
22+ hour, 20+ min ago (75+ words) A new comprehensive review published in the Journal of Nanoparticle Research surveys one of the most quietly promising corners of nanomedicine: carbon dots, nanoscale specks of carbon that are showing remarkable ability to kill bacteria and dismantle the sticky biofilms…...
Tea-Grown Nickel Oxide Nanoparticles Turn Chitosan Films Into Tunable
1+ day, 3+ hour ago (617+ words) A team of materials scientists has shown that ordinary green tea can do far more than steep a soothing drink: its polyphenol-rich extract can grow phase-pure nickel oxide nanoparticles that, when embedded in a biodegradable chitosan matrix, transform a humble…...
Enzyme Trick Turns Bioethanol Waste Oil Into High-Value Renewable Fuel
1+ day, 7+ hour ago (73+ words) A humble byproduct of bioethanol fermentation, long relegated to low-value disposal, could soon find itself blended into the world’s fuel tanks. Researchers at Lund University in Sweden have shown that fusel oil, the mixture of higher alcohols that distillers skim…...
Banana Peel Hydrogel Packed With Drought-Defying Bacteria Boosts Iron and
1+ day, 11+ hour ago (81+ words) Scientists in India have engineered a biodegradable hydrogel bead that carries a drought-tolerant bacterial consortium straight into the root zone of cowpea plants, and the results are striking. In pot trials described in the journal Discover Plants, the formulation nearly…...
Kaolin Recipe Tweak Controls the Water-Trapping Power of Silica Gel
1+ day, 15+ hour ago (762+ words) Researchers in Cameroon have shown that a deceptively simple change in a well-known chemistry recipe—how much metakaolin powder is stirred into a fixed volume of sodium hydroxide solution—can dramatically reshape the internal architecture of the silica gel that…...
Freshwater shrimp kept for twenty hours at a caffeine concentration detected in highly polluted rivers spent less time in the dark than shrimp kept at ordinary background levels, and that shift was about the same size as the one caused by a parasite that manipulates them into being eaten by water birds
2+ day, 1+ hour ago (524+ words) The high tanks held 10,000 nanograms of caffeine per litre and the low tanks held 100, two levels chosen because both occur in real rivers. There was no caffeine-free group at all, so what the experiment measures is the distance between those…...
Efficient Agrobacterium transformation developed for biofuel crop Brassica
2+ day, 6+ hour ago (55+ words) Scientists in Australia have developed a robust and reproducible genetic transformation system for Brassica carinata, an ancient East African oilseed that is rapidly emerging as one of the most promising non-food feedstocks for sustainable aviation fuel and renewable diesel. The…...
A “jack-of-all-trades” enzyme found in American pokeweed: Chinese scientists discover a promiscuous sugar-stitching tool for natural products
3+ day, 12+ hour ago (187+ words) Credit: Zhang Yi, Wang Jinxin, Zhu Yiqing, et al Then came the functional audition: testing each recombinant protein against three triterpene substrates (phytolaccagenin, jaligonic acid, and bayogenin) with UDP-glucose. Only one enzyme passed: PamUGT, converting all three substrates at 30%–40%. Mass…...
