Contrary to the movie Jurassic Park, in which scientists recreate dinosaurs from ancient DNA, genetic material more than about 50 thousand years old cannot be reliably recovered. Nevertheless, a team of scientists has now demonstrated that computers could be used to reconstruct with 98 percent accuracy the DNA of a creature that lived at the time of the dinosaurs more than 75 million years ago--a small, furry nocturnal animal that was the common ancestor of all placental mammals, including humans.
Knowing this ancestral mammal’s complete genome--the sequence of As, Cs, Ts, and Gs in the DNA that made up its chromosomes--would not mean that scientists could bring it to life. (For one thing, synthesizing that much DNA would be prohibitively expensive and technically difficult.)
But that’s not the point. The point is to understand the evolution of humans and other mammals at the molecular level, said David Haussler, professor of biomolecular engineering at the University of California, Santa Cruz. "We will be able to trace the molecular evolution of our genome over the past 75 million years. It’s a very exciting new way to think about our origins, a kind of DNA-based archaeology to understand how we came to be," said Haussler, a Howard Hughes Medical Institute (HHMI) investigator and director of UCSC’s Center for Biomolecular Science and Engineering.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
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...
