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

More than 100 years of data show Pennsylvania...
on May 3, 2019 at 12:06 pm
The prevalence of the most abundant species of ticks found in Pennsylvania has shifted over the last century, according to scientists, who analyzed 117 years' worth of specimens and data submitted primarily by residents from around the state. […]
Spider venom is a dangerous cocktail
on May 2, 2019 at 2:08 pm
Spider venom does not only consist of neurotoxins but also of a multitude of dangerous constituents. Researchers present a summary of many years of spider venom research in a new study and show how various substances present in spider venom interact with each other and thus effectively render the spider's prey defenseless. […]

It might be one of nature's most agile and calculating hunters, but the wolf spider won't harm an insect that literally leaves a bad taste in its mouth, according to new research. […]
Case of tick-borne relapsing fever in Mexico
on April 11, 2019 at 6:51 pm
Tick-borne relapsing fever (TBRF) is a recurring fever caused by exposure to infected Borrelia bacteria. Several cases have been reported in Mexico, but the disease gets little attention. Now, researchers describe the details of an additional case of TBRF in Sonora, Mexico in 2012. […]

Hard carbon nanofiber aerogel becomes superelastic
on May 20, 2019 at 2:47 pm
Conductive and compressible carbon aerogels are useful in a variety of applications. In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons demonstrate great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic "house-of-cards" […]
Bumps on peacock spider make dark spots super-dark
on May 15, 2019 at 12:50 pm
A team of researchers with members from Harvard University, the University of Bonn, the University of Denmark and Yale University has identified bumps on the abdomens of male peacock spiders that make their dark-colored patches look even darker. In their paper published in Proceedings of the Royal Society B, the group describes their study of the bumps and what they learned about them. […]

Coastal organisms trapped in 99-million-year-old...
on May 13, 2019 at 7:00 pm
Most amber inclusions are organisms that lived in the forest. It is very rare to find sea life trapped in amber. However, an international research group led by Prof. Wang Bo from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) reported the first known ammonite trapped in amber in a study in PNAS published on May 13.
