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

- Model predicts where ticks, Lyme disease will...on December 23, 2020 at 12:29 am
By drawing from decades of studies, scientists created a timeline marking the arrival of black-legged ticks, also known as deer ticks, in hundreds of counties across 10 Midwestern states. They used these data - along with an analysis of county-level landscape features associated with the spread of ticks - to build a model that can predict where ticks are likely to appear in future years.
- A gene from ancient bacteria helps ticks spread...on December 10, 2020 at 4:21 pm
One reason ticks spread Lyme disease so well goes back to a unique evolutionary event. Researchers discovered that an antibacterial enzyme in ticks, Dae2, protects them from bacteria found on human skin, while still allowing them to harbor Borrelia burgdorferi, the bacterium that causes Lyme disease. Ticks acquired the gene for this enzyme 40 million years ago from an unknown species of ancient bacteria.
- Spiders in space: Without gravity, light becomes...on December 9, 2020 at 4:51 pm
Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.

A team of zoologists and microbiologists have published a new study showing that common house spiders carry bacteria susceptible to infect people, with the Noble False Widow spiders also carrying harmful strains resistant to common antibiotic treatments.

The spirea aphid, Aphis spiraecola, an invasive pest, has been discovered for the first time in Denmark by University of Copenhagen researchers. The extent of its current distribution remains unknown, but in time, it could prove to be a troublesome pest for Danish apple growers.

A team of researchers from the Centre of the SAVA Region and the University of Antananarivo, both in Madagascar, and one from the University of Goettingen in Germany, has found evidence of a huntsman spider living in a northeastern part of Madagascar creating a trap for tree frogs. In their paper published in the journal Ecology and Evolution, the group describes their observation of a huntsman spider pulling a dead frog into what appeared to be a custom-made leaf trap.

Using the Arecibo 305-m radio telescope, an international team of astronomers has investigated eight binary millisecond pulsars (MSPs). Results of this study, presented in a paper published December 30 on the arXiv pre-print server, provide important information about the properties of these sources.
