Newly published North Carolina State University research into the evolution of birds shows the first definitive fossil proof linking close relatives of living birds to a time when dinosaurs roamed the earth.
Research by paleontologist Dr. Julia A. Clarke, an assistant professor in the marine, earth and atmospheric sciences department at NC State, and colleagues provides unprecedented fossil proof that some close cousins to living bird species coexisted with dinosaurs more than 65 million years ago. Information from a new avian species called Vegavis iaai indicates that these birds lived in the Cretaceous period and must have survived the Cretaceous/Tertiary (K/T) mass extinction event that included the disappearance of all other dinosaurs.
Analysis of fresh evidence from computed tomography (CT) scans of the fossil – which uncovered new bones deep within the rock matrix – and recovery of latex peels made of the specimen just after its discovery in Antarctica in 1992 revealed its importance to avian evolution and that it represented a new species. This partial skeleton is the most complete specimen from the Cretaceous to be found to have its evolutionary relationship to a living bird group. These new data show Vegavis is within the group Anseriformes, which includes ducks and geese.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
