Two new 250 million year-old species of large, meat-eating amphibians have been discovered by researchers, including investigators from McGill University. Their findings published in todays issue of Nature, describe the first and oldest amphibious carnivores from the Republic of Niger in West Africa.
"This the first evidence of carnivores in this area," says McGill paleontologist, and co-author, Hans Larsson. "This find is particularly interesting because the animals we found are not present anywhere else in the world at that time. These animals seemed to be restricted to this one region of Africa that had one of the driest climates on the planet. Animal communities found in other parts of the world are similar to each other, but completely different from those in Niger. We think the shared temperate climates of these other communities may have forced them to evolve independently and in relative isolation from the Niger fauna."
The two species of amphibians discovered are similar to crocodiles in shape. Nigerpeton ricglesi had rounded noses, with small eyes and both small and large fang-like teeth. Saharastega moradiensis had curved horns on the back of its head and an array of small teeth.

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...
