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
Arachnology is the scientific study of spiders and related animals such as scorpions, pseudoscorpions, and harvestmen, collectively called arachnids. Those who study spiders and other arachnids are arachnologists. — Wikipedia

- Microbially produced fibers: Stronger than steel,...on July 20, 2021 at 10:58 pm
A new fiber, made by genetically engineered bacteria is stronger than steel and tougher than Kevlar.
- Repairing hearts with deadly spider venom: Studyon July 19, 2021 at 2:31 pm
A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source - the venom of one of the world's deadliest spiders. A drug candidate developed from a molecule found in the venom of the Fraser Island (K'gari) funnel web spider can prevent damage caused by a heart attack and extend the life of donor hearts used for organ transplants.

Parasitoid wasps are one of the most species rich animal taxa on Earth, but their tropical diversity is still poorly known. Now, scientist have discovered the Dolichomitus meii and Polysphincta parasitoid wasp species previously unknown to science in South America. The new species found in the rainforests entice with their colors and exciting habits.

Jumping spiders can distinguish living from non-living objects in their peripheral vision using the same cues used by humans and other vertebrate animals, according to a study publishing 15th July 2021 in the open-access journal PLOS Biology by Massimo De Agrò of Harvard University in the United States.
- Conductive biopolymers using recycled food...on July 15, 2021 at 12:13 pm
Advanced Materials recently published the findings of Technion researchers who created conductors relevant to solar energy generation, biomedical engineering, and more using by-products of the food industry that would otherwise be discarded as waste. The technology demonstrated in the article allows for the simple, fast, cost effective, and environmentally friendly production of biopolymers, which include application for electrophysiological signal sensing.
