Which way does a mammoth skeleton point in Siberia? No, it’s not a Christmas cracker joke. To find the answer you have to look in a rather surprising place – the Institute of Physics’ new online archive.
Jerry Cowhig, Managing Director of Institute of Physics Publishing and Professor Kathy Sykes, Collier chair of public engagement of science and engineering at Bristol University, are searching the online IOP Journal Archive. Every journal article published by the Institute of Physics since 1874 is now available to subscribers
In an article published in the first edition of Proceedings of the Physical Society in 1874, John Rae writes about the physical properties of ice and mammoth remains. He put forward a theory as to why so many of the mammoth skeletons found near the Yenesei river in Siberia had been found with their heads pointing southwards. He said that if these mammoths died in or near the river, their bodies would get swept down the river to the shallow area near the mouth. The mammoth’s head, weighed down by its tusks and skull, would drag along the bottom and in shallow water the body would still float with the current – in a similar way to a boat pulling on an anchor. When the river froze in winter, the mammoths would become frozen in this position – with their heads pointing southwards with the flow. As this river flows from south to north, the heads would be pointing southwards when they froze.
This fascinating article can be accessed for the first time on the World Wide Web on the IOP Journal Archive. Every journal article published by the Institute of Physics since 1874 is now available to subscribers – that is over 500 volume-years of journals, over 100,000 articles and over one million pages of scientific research.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
