Approximately 10,000 years after the last mammoths used to roam across the North American and Eurasian spaces, they still remain an exciting subject of inquiry for researchers. Mammoths and elephants belong to the most ancient group of mammals, therefore, when studying mammoths the researchers reveal secrets of evolutionary origin of contemporary species. Discussions continue about genetic kinship of mammoths and contemporary elephants.
Now, Russian researchers working at several institutes of the Russian Academy of Sciences, Russian Academy of Medical Sciences and Lomonosov Moscow State University, as well as at Universities of Massachusetts and California managed to obtain independent proof this kinship. The researchers managed to reconstruct the most ancient (as of today) complete DNA sequence of mitochondrial genome received from remains of a mammoth that died about 33,000 years ago.
Professor Rogayev, Doctor of Biology, and his colleagues (from UMASS MS, Scientific Center of Mental Health, Russian Academy of Medical Sciences, Institute of General Genetics, Russian Academy of Sciences, Moscow State University, UCSD) published the article entitled “Complete mitochondrial genome and phylogeny of Pleistocene mammoth Mammuthus primigenius” on February 7 in the Plos Biology magazine, Public Library of Science (Plos), where they described the DNA sequence of 16,842 signs (16,842 pairs of nucleotides). This is a complete mitochondrial genome of a mammoth, whose remains had been extracted from the permafrost. The remains date back to the Pleistocene era – the period of time from 10,000 through 1.6-1.9 million years B.C. The investigations have showed that mammoths and Asia’s elephants are related species that drifted apart in the course of evolution soon after separation of their common ancestor from the line of African elephants.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
