Quad launches Elegan speakers: high-end sound, approachable price

Quad has unveiled two Elegan Series loudspeakers—Elegan 1 (standmount) and Elegan 2 (floorstanding)—featuring woven Kevlar drivers in two-way and three-way designs, with high-density cabinets, internal bracing and waveguides for wide dispersion and improved midrange clarity. The Elegan 1 is priced at £749 / $995 / AU$1,699 per pair, while the Elegan 2 costs £1,499 / $1,995 / AU$3,499 per pair. Finishes are deep matte black or walnut veneers, and weights are 8.9 kg per Elegan 1 and 27.8 kg per Elegan 2. Quad positions them as spiritual successors to the L Series from the early 2000s.

Darwin’s Bark Spider Spins Ultra-Tough Silk and Bridges Rivers Across Madagascar

A Madagascan spider, Darwin’s bark spider (Caerostris darwini), weaves dragline silk that is the toughest biological material measured to date, absorbing more energy than Kevlar by roughly tenfold; its webs span rivers with bridge lines up to 25 meters. The toughness arises from a mix of solid strength and unusually high elasticity, and researchers note the silk isn’t yet mass-producible due to the impossibility of farming spiders. The work also highlights bioprospecting as a targeted approach to discovering extraordinary natural materials.

Tiny Madagascar Spider Weaves 80-Foot Webs with Kevlar-Tough Silk

A tiny Darwin’s bark spider in Madagascar builds webs spanning rivers up to 80 feet long, using dragline silk that absorbs energy far better than Kevlar—about ten times tougher—setting a new benchmark for natural materials and prompting questions about the silk’s molecular basis.

Revolutionary Microchip Material Outperforms Kevlar by 10-Fold

Researchers at Delft University of Technology have developed a new material called amorphous silicon carbide (a-SiC) that is ten times stronger than Kevlar, rivaling the strength of graphene and diamonds. This material could have applications beyond protective gear, including enabling highly sensitive microchips.

Bulletproof Suit Inspired by John Wick's Style

Bulletproof suits like the ones seen in the John Wick movies actually exist, but they don't have the magic physics-defying powers of the movie version. Most real-life body armor is made from Kevlar or similar ballistic fibers, but they are not completely bulletproof. A prototype Kevlar suit that supposedly cost a little under $100,000 to produce has been created, but carbon nanotubes from Garrison are the best option for a bulletproof suit. However, the laws of physics still apply, and serious damage is likely to occur even with a bulletproof suit.
