Flies mosquitoes beware slingshot spider
2020/8/21
Running into an unseen spiderweb in the woods can be scary enough, but what if you had to worry about a spiderweb -- and the spider -- being catapulted at you? That's what happens to insects in the Am...
Efficacy of Certain Common Ferns against Red Spider Mite Oligonychus coffeae and Tea Mosquito Bug Helopeltis theivora Infesting Tea

2018/3/5
In search for botanicals as an alternative remedy to synthetic chemicals in the pest control of tea plantations, ferns
such as Adiantum raddianum, Asplenium aethiopicum, Cyclosorus interruptus, Dicra...
A tiny virus that may sting like a black widow spider.That is one of the surprise discoveries made by a pair of Vanderbilt biologists when they sequenced the genome of a virus that attacks Wolbachia, ...
Light Used to Measure the ‘Big Stretch’ in Spider Silk Proteins
Light Big Stretch Spider Silk Proteins
2016/2/23
While working to improve a tool that measures the pushes and pulls sensed by proteins in living cells, biophysicists at Johns Hopkins say they’ve discovered one reason spiders’ silk is so elasti...
The Hawaiian Islands are renowned for some
of the most spectacular species radiations in the world. Most of
these radiations have been attributed to single colonization
events, although the evidenc...
The Spider Algorithm
Spider Algorithm
2015/8/26
One of the reasons complex analytic dynamics has been such a successful subject is the deep relation that has surfaced between conformal mapping, dynamics and combinatorics. The object of the spider a...
For the first time, researchers have created a visual atlas and dictionary of terms for the many strange features on the fearsome-looking jaws of a little known group of arachnids. Called camel spider...
Antenna-coupled TES bolometers for the SPIDER experiment
cosmic microwave background polarization millimeter wave instrumentation
2014/12/23
SPIDER is a proposed balloon-borne experiment designed to search for the imprints of gravity waves on the polarization of the cosmic microwave background radiation. The required wide frequency coverag...
SPIDER - V. Measuring Systematic Effects in Early-Type Galaxy Stellar Masses from Photometric SED Fitting
Measuring Systematic Effects Early-Type Galaxy Stellar Masses Photometric
2011/10/17
We present robust statistical estimates of the accuracy of early-type galaxy stellar masses derived from spectral energy distribution (SED) fitting as functions of various empirical and theoretical as...
Entire functions for which the escaping set is a spider's web
Entire functions escaping set spider's web
2011/1/19
We construct several new classes of transcendental entire func-tions, f, such that both the escaping set, I(f), and the fast escaping set,A(f), have a structure known as a spider’s web. We show that s...
Building on recent work by Rippon and Stallard, we explore the intricate structure of the spider's web fast escaping sets associated with certain transcendental entire functions. Our results are expr...
Spiders may not be everybody's idea of natural beauty, but nobody can deny the artistry in the webs that they spin, especially when decorated with water baubles in the morning dew. Inspired by this sp...
