A spacetime tremor and a celestial light show.
sciencemag.org SCIENCE IL L U S T R A T IO N : E S O / L . C A L Ç A D A / M . K O M M E S S E R F our times in the past 2 years, physicists working with mammoth gravitationalwave detectors have sensed something go bump in the dark, sending invisible ripples through spacetime. This week, they announced the detection of a fifth such disturbance—but this time astronomers saw it, too, at every wav...
متن کاملLight and X-ray scattering show decorin to be a dimer in solution.
Decorin is a widely distributed member of the extracellular matrix small leucine-rich repeat glycoprotein/proteoglycan family. For investigation of its physical properties, decorin from two sources (young steer skin and a recombinant adenovirus) was used. The first sample was extracted into 7 m urea and purified, while the second was isolated from medium conditioned by 293A cells infected with ...
متن کاملVaccinia virus proteins A36 and F12/E2 show strong preferences for different kinesin light chain isoforms
Vaccinia virus (VACV) utilizes microtubule-mediated trafficking at several stages of its life cycle, of which virus egress is the most intensely studied. During egress VACV proteins A36, F12 and E2 are involved in kinesin-1 interactions; however, the roles of these proteins remain poorly understood. A36 forms a direct link between virions and kinesin-1, yet in its absence VACV egress still occu...
متن کاملA Time-symmetric Hubble-like Law: Light Rays Grazing Randomly Moving Galaxies Show Distance-Proportional Redshift
A new class of dissipative structures is proposed that live in real space rather than phase space. A light ray passing through a soup of randomly moving gravitating masses is a case in point. It suffers a “dynamic path elongation” since the random pushes and pulls have a greater probability of increasing than decreasing its path length. Time reversal then re-shrinks the path in question in a co...
متن کاملStatistical Power Considerations Show the Endocrine Disruptor Low-Dose Issue in a New Light
BACKGROUND The endocrine disruptor field has been vexed by difficulties in reproducing various claims of effects at unusually low doses. In previous analyses, variations in control responses from experiment to experiment and problems with observing effects in positive controls have been identified as possible explanations of the resulting impasse. OBJECTIVE In this article, we argue that both...
