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

The abundance of large orb web spiders in the Swiss midland has declined drastically over the last 40 years. The main reason for this is the shrinking food supply available to these insectivorous animals.
Spider combs tame unruly nanofibers
on April 22, 2020 at 3:23 pm
Cribellate spiders spin thousands of tiny nanofibers into sticky threads. To keep from getting caught in their own webs, these spiders use a nonstick comb on their back legs. Now, researchers have patterned an antiadhesive nanostructure inspired by this comb onto a foil surface, creating a handy tool to control sticky lab-made nanomaterials for medical, smart textile and other applications.

Stream pollution from mountaintop mining doesn't...

Since the 1980s, a mountaintop mine in West Virginia has been leaching selenium into nearby streams at levels deemed unsafe for aquatic life. Now, even though the mine is closed, a new study finds high concentrations of selenium in emerging stream insects and the spiders that eat them along the banks, an indication that the contaminant moves from water to land as it moves up the food chain.
To prevent tick encounters, where you dump your...

While many homeowners heed the advice to clear their lawns of fallen leaves in autumn to avoid creating tick-friendly habitat in high-use areas, a new study on tick abundance in leaf litter says raking or blowing leaves just out to the forest edge is not enough. In fact, dumping leaves where grass meets woods may inadvertently create an ideal habitat for blacklegged ticks.

A 425-million-year-old millipede fossil from the Scottish island of Kerrera is the world's oldest "bug"—older than any known fossil of an insect, arachnid or other related creepy-crawly, according to researchers at The University of Texas at Austin.

For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.
Peculiar behavior of the beetle Toramus larvae,...
on May 22, 2020 at 2:07 pm
When studying the larval morphology of Toramini (Coleoptera: Erotylidae) we found that larvae of the genus Toramus attach their exuviae to their distal abdomen, with each exuvia from the preceding instar attached to the next to form a vertical pile. Exuvial attachment is facilitated by modified hook-like setae with flattened shafts inserted into the exuvia of the previous instar. We discuss the possibility that the exuvial attachment serves as a kind of autotomy—"exuvial autotomy."
Q&A: How synthetic biology will change us

John Cumbers is founder and CEO of SynBioBeta, a global network of biological engineers and entrepreneurs in a promising new scientific field known as "synthetic biology." The San Francisco Bay Area is a leader in this little-known but fast-growing industry, which reassembles the building blocks of life in imaginative and diverse ways.
Enrichment programs help children build knowledge
on May 21, 2020 at 3:04 pm
How we organize information plays an integral role in memory, reasoning and the ability to acquire new knowledge. In the absence of routine education programs, the pandemic is exacerbating the disparities in educational opportunities available for children to develop new skills. While children of higher socio-economic means often benefit from enrichment programs, these opportunities are unfortunately not available to every child.
