Some researchers have doubts that mammoths lived in the cold climate zones. Recently, Russian scientists have received strong evidence of woolly mammoths’ frost-resistance – they possessed sebaceous glands. The trip to visit mammoths was paid by the International Scientific and Technical Center, and the researchers’ search for sebaceous glands was supported by the Federal Target Scientific and Technical Program entitled “Investigations and Developments for Science and Engineering Priority Guidelines in 2002-2006”.
Specialists of the VECTOR State Research Center for Virology and Biotechnology and the Zoological Institute (Russian Academy of Sciences) have discovered sebaceous glands in the skin of woolly mammoths, the scientific community unsuccessfully looking for sebaceous glands for more than a hundred years. As sebaceous glands are an instrument of adaptation to cold climate, the discovery by Russian scientists serves a convincing argument in the dispute whether the mammoths did live in the frost.
The doubting researchers claim that we can restore appearance of zoolites, but not the conditions they used to live in. According to some data, the ice age climate was much warmer then it is believed, and therefore, the mammoths probably did not have to endure long ice-cold winters. However, questions arise not only about the climate of Beringia, but also about the mammoth’s constitution. Although its appearance is habitual to us, many physiological peculiarities of this fur mountain with tusks are hard to reconstruct. For example, researchers failed to find mammoth’s cutaneous, sudoriferous and sebaceous glands. The hair was known to be present, but sebaceous glands accompanying it were not in place. However, the elephant, mammoth’s alive next-of-kin, does not possess them. Nevertheless, mammoths used to live in other latitudes and they are somehow entitled to differ anatomically from elephants.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
