Ancient properties of spider silks revealed by the complete gene sequence of the prey-wrapping silk protein (AcSp1). [PDF]
, 2012 Spider silk fibers have impressive mechanical properties and are primarily composed of highly repetitive structural proteins (termed spidroins) encoded by a single gene family.

The $\textit{False Widow}$ Link Between Neutron Star X-ray Binaries and Spider Pulsars [PDF]
, 2023 The discovery of transitional millisecond pulsars (tMSPs) provided conclusive proof that neutron star (NS) low-mass X-ray binaries (LMXBs) comprise part of the evolutionary pathway towards binary millisecond pulsars (MSPs). Redback and black widow `spider' pulsars are a sub-category of binary MSPs that `devour' their companions through ablation - the ...

Spiders in Brazil: from arachnidism to potential therapeutic use of their venom part 1 of 2 [PDF]
, 2022 Spider envenomation, generically known as arachnidism, is described in many places around the world. In terms of medical importance, the following genera of animals stand out as the main origin of the morbid condition: Atrax (Sidney funnel web spider ...

Venomous spiders of Albania –does an increase of temperature influence the toxicity of spider venom?
Toxicon: X, 2022 Black widow spiders (Latrodectus sp.) are distributed worldwide, and in Albania the L. tredecimguttatus Rossi, 1790 has been the dominant spider. Other medically important spiders in Albania include the brown recluse with symptoms known as loxoscelism ...

First measurement of the total gravitational quadrupole moment of a black widow companion [PDF]
, 2020 We present the first measurement of the gravitational quadrupole moment of the companion star of a spider pulsar, namely the black widow PSR J2051$-$0827. To this end we have re-analysed radio timing data using a new model which is able to account for periastron precession caused by tidal and centrifugal deformations of the star as well as by general ...

Polarization of Intrabinary Shock Emission in Spider Pulsars [PDF]
arXiv, 2023 In `spider' pulsars, the X-ray band is dominated by Intrabinary Shock (IBS) synchrotron emission. While the double-peaked X-ray light curves from these shocks have been well characterized in several spider systems (both black widows and redbacks), the polarization of this emission is yet to be studied.

Neutron star mass estimates from gamma-ray eclipses in spider millisecond pulsar binaries [PDF]
, 2023 Reliable neutron star mass measurements are key to determining the equation-of-state of cold nuclear matter, but these are rare. "Black Widows" and "Redbacks" are compact binaries consisting of millisecond pulsars and semi-degenerate companion stars.
