spider : any of an order (Araneae synonym Araneida) of arachnids having a short, usually unsegmented abdomen linked to the cephalothorax by the pedicel, chelicerae modified into poison fangs, and two or more pairs of spinnerets at the posterior end of the abdomen for spinning threads of silk for various uses (as in making cocoons for their eggs or webs to catch prey) — Webster
Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. — Wikipedia

Mystery of how black widow spiders create...
on October 22, 2018 at 7:00 pm
Researchers at Northwestern University and San Diego State University (SDSU) have better unraveled the complex process of how black widow spiders transform proteins into steel-strength fibers. This knowledge promises to aid scientists in creating equally strong synthetic materials. […]
Spider swarm cloaks Greek lake in 1,000-metre web
on October 18, 2018 at 2:40 pm
Lake Vistonida in northern Greece has become an arachnophobe's worst nightmare after it was cloaked recently by massive webs spun by hundreds of thousands of small spiders. […]
NASA's Fermi mission energizes the sky with...

Long ago, sky watchers linked the brightest stars into patterns reflecting animals, heroes, monsters and even scientific instruments into what is now an official collection of 88 constellations. Now scientists with NASA's Fermi Gamma-ray Space Telescope have devised a set of modern constellations constructed from sources in the gamma-ray sky to celebrate the mission's 10th year of operations. […]
3-D printing hierarchical liquid-crystal-polymer...
on October 9, 2018 at 11:34 am
Biological materials from bone to spider-silk and wood are lightweight fibre composites arranged in a complex hierarchical structure, formed by directed self-assembly to demonstrate outstanding mechanical properties. When such bioinspired stiff and lightweight materials are typically developed for applications in aircraft, automobiles and biomedical implants, their manufacture requires energy and labor-intensive fabrication processes. The manufactured materials also exhibit brittle fracture […]
New security scanners safely detect threats from...
on October 8, 2018 at 1:20 pm
With increased threats to soft targets, security personnel need tools to detect menaces in fast moving, crowded environments. The EU-funded SPIDERS project introduces 'MM-Imager', a safe approach working in real-time which can scan bodies at short distances for hidden objects. […]
