Writing and deleting magnets with lasers

Wed, 04/18/2018 - 15:16
Scientists have found a way to write and delete magnets in an alloy using a laser beam -- a surprising effect. The reversibility of the process opens up new possibilities in the fields of material processing, optical technology, and data storage.

Robot developed for automated assembly of designer nanomaterials

Wed, 04/18/2018 - 15:16
Engineers have developed a robot that can identify, collect, and manipulate two-dimensional nanocrystals. The robot stacked nanocrystals to form the most complex van der Waals heterostructure produced to date, with much less human intervention than the manual operations previously used to produce van der Waals heterostructures. This robot allows unprecedented access to van der Waals heterostructures, which are attractive for use in advanced electronics.

Flexible TVs and high performance wearable smart tech one step closer

Wed, 04/18/2018 - 15:11
Flexible televisions, tablets and phones as well as 'truly wearable' smart tech are a step closer thanks to a nanoscale transistor just created.

An AI that makes road maps from aerial images

Tue, 04/17/2018 - 17:00
Map apps may have changed our world, but they still haven't mapped all of it yet. In particular, mapping roads can be tedious: even after taking aerial images, companies like Google still have to spend many hours manually tracing out roads. As a result, they haven't yet gotten around to mapping the vast majority of the more than 20 million miles of roads across the globe.

Digital remains should be treated with the same care and respect as physical remains

Tue, 04/17/2018 - 17:00
A new study advises that people's digital remains, such as, social media activity and online history, should be viewed in the same way as the human body, and treated with care and respect rather than manipulated for commercial gain. The paper suggests regulation akin to those used in museums and commercial use of organic human remains, is the best way to create explicit boundaries around acceptable afterlife activity and grief exploitation.

Machine learning techniques may reveal cause-effect relationships in protein dynamics data

Tue, 04/17/2018 - 15:57
Machine learning algorithms excel at finding complex patterns within big data, so researchers often use them to make predictions. Researchers are pushing the technology beyond finding correlations to help uncover hidden cause-effect relationships and drive scientific discoveries. Researchers are integrating machine learning techniques into their work studying proteins. One of their challenges has been a lack of methods to identify cause-effect relationships in data obtained from molecular dynamics simulations.

Algorithm to locate fake users on many social networks

Tue, 04/17/2018 - 15:57
Researchers have developed a new generic method to detect fake accounts on most types of social networks, including Facebook and Twitter.

Invertebrates inspire first fully 3-D printed active materials for robots

Tue, 04/17/2018 - 13:00
To overcome the material rigidity and actuation limitations in current robotic systems, a joint US Army Research Laboratory and University of Minnesota research project sought inspiration from invertebrates.

Researchers use search engines, social media to predict syphilis trends

Mon, 04/16/2018 - 18:54
New research finds that internet search terms and tweets related to sexual risk behaviors can predict when and where syphilis trends will occur.

Quantum shift shows itself in coupled light and matter

Mon, 04/16/2018 - 18:25
Researchers observe and measure a Bloch-Siegert shift in strongly coupled light and matter in a vacuum. The project could aid in the development of quantum computers.

Two robots are better than one: 5G antenna measurement research

Mon, 04/16/2018 - 18:24
Researchers continue to develop new antenna measurement methods, this time for future 5G wireless communications systems.

Face recognition technology that works in the dark

Mon, 04/16/2018 - 18:24
Researchers have developed an artificial intelligence and machine learning technique that produces a visible face image from a thermal image of a person's face captured in low-light or nighttime conditions. This development could lead to enhanced real-time biometrics and post-mission forensic analysis for covert nighttime operations.

Scientists uncover how to stop cyber intrusions

Mon, 04/16/2018 - 16:15
Researchers have found a proverbial smoking gun signature of the long sought-after Majorana particle, and the find, they say, could block intruders on sensitive communication networks.

BESSY II sheds light on how the internal compass is constructed in magnetotactic bacteria

Mon, 04/16/2018 - 14:58
Bacteria exist in many shapes and with very different talents. Magnetotactic bacteria can even sense the earth's magnetic field by making use of magnetic nanoparticles in their interior that act as an internal compass. Experts have now examined the magnetic compass of Magnetospirillum gryphiswaldense at BESSY II. Their results may be helpful in designing actuation devices for nanorobots and nanosensors for biomedical applications.

Artificial intelligence accelerates discovery of metallic glass

Fri, 04/13/2018 - 18:45
Combining artificial intelligence with experimentation sped up the discovery of metallic glass by 200 times. The new material's glassy nature makes it stronger, lighter and more corrosion-resistant than today's best steel.

When superconductivity disappears in the core of a quantum tube

Fri, 04/13/2018 - 17:36
Predicting the behavior of electrons in a material is not easily done. Physicists have replaced the electrons with ultra-cold neutral lithium atoms that they had circulated in a one-dimensional quantum tube. The scientists were able to confirm an unusual state of matter that retains its insulation regardless of the level of attraction between the particles. This work opens the way to new materials with atypical properties.

Quantum physicists achieve entanglement record

Fri, 04/13/2018 - 15:06
Entanglement is of central importance for the new quantum technologies of the 21st century. A research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of 20 quantum bits. The physicists are pushing experimental and theoretical methods to the limits of what is currently possible.

Chemistry: Observing biological nanotransporters

Fri, 04/13/2018 - 13:38
A research team was able to describe with atomic detail how molecules are transported through biological membranes. Computer simulations and spectroscopic experiments provided insights into the work of so-called ABC transporters. These proteins play an important role in the drug resistance of tumor cells and bacteria.
