A debris disk around an isolated young neutron star

Article Abstract:

Pulsars are rotating, magnetized neutron stars that are born in supernova explosions following the collapse of the cores of massive stars and if some of the explosion ejects falls to escape, it might fall back onto the neutron star or it might possess sufficient angular momentum to form a disk. Fallback disks could dramatically affect the early evolution of pulsars, yet there are few observational constraints on whether significant fallback occurs or even the actual existence of such disks.

Mechanism of silk processing in insects and spiders

Article Abstract:

The identification of emulsion formation and micellar structures from aqueous solutions of reconstituted silkworm is discussed. The morphological features of these silk materials are described to be similar to those in native silkworm fibres.

Silk's secrets

Article Abstract:

The production of silk, which was solely by insects and spiders, is described now to be a biotechnological reality. The ways in which silk proteins can be processed into fibres are explained.
