The latest technology news from Science Daily

A laboratory is putting chemistry to work on a simple, inexpensive way to identify falsified or substandard antibiotics, offering a practical solution to a very real problem. The researchers have created a paper-based test that can quickly determine whether an antibiotic sample is appropriate strength, or diluted with filler substances like baking soda. Similar to the mechanism of a home pregnancy test, a strip of paper turns a distinctive color if a falsified antibiotic is present.

The critical, structural changes that enveloped viruses, such as HIV, Ebola and influenza, undergo before invading host cells have been revealed by scientists using nano-infrared spectroscopic imaging.

Researchers have used computer models on the Stampede2 supercomputer to replicate the dispersal of gases from the April 4, 2017 chemical weapons attack in northwest Syria. The simulations were able to capture real world conditions despite a scarcity of information. Recently, the team developed a coarse model that uses seasonal conditions as background information to speed up calculations, reducing forecasting time from days to minutes.

After an earthquake, hurricane, tornado or other natural hazard, it's considered a win if no one gets hurt and buildings stay standing. But an even bigger victory is possible: keeping those structures operational. This outcome could become more likely with improved standards and codes for the construction of residential and commercial buildings, according to a new report.

Researchers who tested two commercially available baby monitors are raising serious concerns about the accuracy of these products, which are marketed to parents, but are not regulated by the US Food & Drug Administration.

Researchers have significantly upgraded the interaction system for the conversational android ERICA, by implementing 'backchanneling' and 'attentive listening' ability.

Researchers have investigated heat transport in a model system comprising nanometer-thin metallic and magnetic layers. Similar systems are candidates for future high-efficiency data storage devices that can be locally heated and rewritten by laser pulses (Heat-Assisted Magnetic Recording). Measurements taken with extremely short X-ray pulses have shown that the heat is distributed a hundred times slower than expected.

An algorithm-based system that identifies telltale linguistic cues in fake news stories could provide news aggregator and social media sites like Google News with a new weapon in the fight against misinformation.

Scientists using an innovative quantum simulation technique have made one of the first observations of a mobility edge in a low-dimensional system. Scientists were able to combine a disordered virtual material -- in this case a pair of coupled 1D chains -- with artificial magnetic fields to explore this phenomenon.

Ceramic materials are used in nuclear, chemical and electrical power generation industries because of their ability to withstand extreme environments. However, at high temperatures, ceramics are susceptible to thermal-shock fractures caused by rapid temperature-changing events, such as cold water droplet contact with hot surfaces. In a novel interdisciplinary approach, engineers report the use of a cheap, simple, water-repelling coating to prevent thermal shock in ceramics.
