A materials scientist’s dream come true

Materials can deform plastically by atomic-scale line defects called dislocations. Many technical applications are based on this fundamental process, such as forging, but we also rely on the power of dislocations in our everyday life: in the crumple zone of cars dislocations protect lives by transforming energy into plastic deformation. Researchers have now found a way of manipulating individual dislocations directly on the atomic scale.

Structural fluctuation evaluation in substances from measurement data

Microstructure analysis of materials is a key technology for new material research. Using an information extraction technique called sparse modeling, a collaboration of researchers has developed the world's first method of analyzing a material's atomic structure using only measured data. This method needs no prior assumptions of atomic structure, which are required in conventional microstructure analysis methods. This new approach is expected to improve the functionality of and give longer life to batteries.

Switching DNA and RNA on and off

DNA and RNA are naturally polarized molecules. Scientists believe that these molecules have an in-built polarity that can be reoriented or reversed fully or in part under an electric field. In a new study scientists show that all the DNA and RNA building blocks, or nucleobases, exhibit a non-zero polarization in the presence of polar atoms or molecules such as amidogen and carbonyl.

What Vitalik Buterin’s tweetstorm means for the future Ethereum blockchain

It took 75 tweets, but Ethereum blockchain founder Vitalik Buterin has clarified the roadmap for implementing a new consensus mechanism that promises to greatly increase the speed with which new entries can be added to the distributed electronic ledger technology.
Buterin devoted most of the tweets to explaining the history of Ethereum developer efforts to create a Proof of Stake (PoS) consensus mechanism that would streamline the process while also combating nefarious attacks to control blockchain content.

DHCP defined and how it works

The ability to network devices quickly and easily is critical in a hyper-connected world, and although it has been around for decades, DHCP remains an essential method to ensure that devices are able to join networks and are configured correctly.
DHCP greatly reduces the errors that are made when IP addresses are assigned manually, and can stretch IP addresses by limiting how long a device can keep an individual IP address.
[ Now read 20 hot jobs ambitious IT pros should shoot for. ] DHCP definition DHCP stands for dynamic host configuration protocol and is a network protocol used on IP networks where a DHCP server automatically assigns an IP address and other information to each host on the network so they can communicate efficiently with other endpoints.

Surface Pro 4 firmware update blamed for touchscreen and pen malfunctions

Microsoft’s Surface folks have been on a mission lately, replacing almost all of the firmware and drivers in almost all of the recent Surface machines. It’s as if, golly, somebody finally figured out that the enormous number of Surface bugs have their root in something buried deep inside.
The jury’s still out on the efficacy of most of those firmware/driver updates, but a problem has, uh, surfaced specifically with the Surface Pro 4 firmware/driver updates released on July 26.
