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

Scientists discover why tarantulas come in vivid...
on September 24, 2020 at 2:19 pm
Researchers find support for new hypotheses: that tarantulas' vibrant blue colors may be used to communicate between potential mates, while green coloration confers the ability to conceal among foliage. Their research also suggests that tarantulas are not as color-blind as previously believed, and that these arachnids may be able to perceive the bright blue tones on their bodies.
Toxic masculinity: Why male funnel web spiders...
on September 21, 2020 at 7:13 pm
A team of researchers has revealed why male funnel web spiders develop much deadlier venom than their female counterparts. The team has spent 20 years investigating delta-hexatoxins, the venom peptides that make funnel web spider venom so dangerous.

Molecules from the venom of one of the world's largest spiders could help researchers tailor pain blockers for people with irritable bowel syndrome (IBS).
A new species of spider

Spider home invasion season: why the media may be...
on October 1, 2020 at 1:41 pm
Spiders have an unfortunate media presence. No number of studies emphasising their ecological value or the potential of their silks to inspire wonder materials can overcome the negative press. The more emotive and sensational the coverage, the more likely it is to travel.
Very Large Telescope spots galaxies trapped in...
on October 1, 2020 at 8:12 am
With the help of ESO's Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes, one of which exists at the centre of our Milky Way, formed and grew to their enormous sizes so quickly. It supports the theory that black holes can grow rapidly […]

Future offshore oil and gas fields are most likely to be "satellite developments" that are less expensive and emit less greenhouse gasses than other fields because they do not require new production platforms. An innovative Norwegian computational tool called "Slug Capturing 2" is now enabling the design of longer pipelines that will allow many more fields to be developed as satellites.

Why are some tarantulas so vividly colored? Scientists have puzzled over why these large, hairy spiders, active primarily during the evening and at night-time, would sport such vibrant blue and green colouration—especially as they were long thought to be unable to differentiate between colors, let alone possess true color vision.

A new report on biological collections from The National Academies of Sciences, Engineering, and Medicine points to the need for sustainability, digitization, recruitment of a diverse workforce, and infrastructure upgrades to meet the challenges now facing science and society. The report, "Biological Collections: Ensuring Critical Research and Education for the 21st Century," says these collections are a critical part of the nation's science and innovation infrastructure and a fundamental […]
