Live Cells Have Been Found In Frozen Mammoth

05.02.2003


’We consider these cells conditionally alive’, explains Professor Vladimir Repin, leader of the research team, ’because they were fixed in formalin to preserve after extracting them from the mammoth body in the field. However, the inner structure of these cells is undamaged, so we suggest that the rest frozen tissues contain similar cell layers, which could be defrozen’. The sensational finding was made by Oleg Taranov, a member of the research team.

The story is as follows. Last summer an international paleontology expedition supported by International Science and Technology Center worked in Yakutia. Russian scientists from the Institute of Applied Ecology of the North, Yakutsk and NPO Vector and Japanese scientists from several research centers took part in the expedition. The researchers have found two well-preserved mammoth’s legs, which were frozen in the soil on the bank vault of the Maksunokha-River near Deputatsky village not far from Yakutsk. The valuable finding was not dug out, but washed out with a water jet. The animal’s legs with muscles and skin, covered with reddish fur were put into the freezer and transported to Yakutsk, into the famous Museum of Mammoth.

One may wonder, why the finding of living mammoth cells is so important for the scientists. The point is the amazing idea of Japanese biologists to clone the extinct animal. Maybe, DNA samples from the found cells will do for these plans.



Last summer Russian scientists found a frozen mammoth in Yakutia. In the subcutaneous cellular tissue of the animal they discovered living cells with intact nuclei. Possibly, these cells are good enough for cloning the extinct mammal.

Im Focus: The taming of the light screw

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...

Im Focus: Magnetic micro-boats

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...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

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...

Im Focus: Stellar cartography

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...

Im Focus: Heading towards a tsunami of light

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...
