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

- Possible alternative treatment for Lyme diseaseon October 14, 2021 at 5:11 pm
Researchers have described a new antibiotic that appears to have the potential to cure Lyme disease.

Early in animal evolution, complex life was mostly limited to the sea floor. But a few organisms evolved to move through the water, giving them a big competitive advantage over those left scuttling around in the mud.
- Spider silk’s supposed 'healing properties'...on October 5, 2021 at 4:47 pm
As far back as ancient Rome, spider silk has been used as a remedy to treat everything from skin lesions to warts. In the past, doctors have covered open wounds in cobwebs or advised patients to place cocoons on infected teeth. In modern times, however, the literature contains conflicting reports of whether or not spider silk has antimicrobial properties. Researchers have now revisited these old experiments and debunk the myth of antibiotic spider silk.

A previously unknown virus that can infect humans and cause disease has been identified by scientists in Japan. The novel infectious virus, named Yezo virus and transmitted by tick bites, causes a disease characterized by fever and a reduction in blood platelets and leucocytes.
- Augmented reality helps tackle fear of spiderson September 20, 2021 at 2:09 pm
Researchers have developed an augmented reality app for smartphones in order to help people reduce their fear of spiders. The app has already shown itself to be effective in a clinical trial, with subjects experiencing less fear of real spiders after completing just a few training units with the app at home.

They may be tiny, but mites have shown that we have something to learn from them. Researchers from Japan have discovered that mites can aid in the understanding of the evolution of reproductive barriers.
- Researchers describe new tardigrade fossil found...on October 5, 2021 at 11:00 pm
Tardigrades, also known as water bears, are a diverse group of charismatic microscopic invertebrates that are best known for their ability to survive extreme conditions. A famous example was a 2007 trip to space where tardigrades were exposed to the space vacuum and harmful ionizing solar radiation, and still managed to survive and reproduce after returning to Earth. Tardigrades are found in all the continents of the world and in different environments including marine, freshwater, and […]

- Compelling evidence of the connection between AMR...on September 30, 2021 at 12:50 pm
Antimicrobial resistance (AMR), the resistance of micro-organisms to antibiotics, antivirals or antifungals, is a huge global problem. Left unchecked, AMR threatens to become one of the world's biggest health problems, surpassing diabetes and cancer. As more bugs become drug resistant we will lose the ability to rely on antibiotics for routinely treatments—including for basic surgery, cancer treatments or cesareans.
- First mixopterid eurypterids found in Chinaon September 29, 2021 at 12:47 pm
Eurypterids, normally known as sea scorpions, are an important group of Paleozoic chelicerate arthropods. As a "star animal" in the Silurian (about 430 million years ago) sea, its evolutionary history and paleoecological significance have always attracted attentions.
