University of Chicago scientists are part of an international research team that has discovered superconductivity—the ability to conduct electricity perfectly—at the highest temperatures ever recorded.

A cache of microscopic fossils from the Arctic hints that fungi reached land long before plants.

More than 130 years after its discovery, scientists just got their first high-tech peek at the unexpected crystal structure inside the Ram’s Horn.

The nonprofit Allen Institute in Seattle has produced a visualization of human cell division that promises to be useful for professional scientists and curious amateurs alike.

During the height of the Civil War, the Confederate Surgeon General commissioned a guide to traditional plant remedies of the South, as battlefield physicians faced high rates of infections among the wounded and shortages of conventional medicines. A new study of three of the plants from this guide—the white oak, the tulip poplar and the devil’s walking stick—finds that they have antiseptic properties.

Scientific Reports is publishing the results of the study led by scientists at Emory University. The results show that extracts from the plants have antimicrobial activity against one or more of a trio of dangerous species of multi-drug-resistant bacteria associated with wound infections: Acinetobacter baumannii, Staphylococcus aureus and Klebsiella pneumoniae.

“Our findings suggest that the use of these topical therapies may have saved some limbs, and maybe even lives, during the Civil War,” says Cassandra Quave, senior author of the paper and assistant professor at Emory’s Center for the Study of Human Health and the School of Medicine’s Department of Dermatology.

Governments are becoming ever more reliant on digital technology, making them more vulnerable to cyber attacks. In 2007, Estonia was attacked by pro-Russian hackers who crippled government servers, causing havoc. Cyber attacks in Ukraine targeted the country’s electricity grid, while Iran’s nuclear power plants were infected by malware that could have led to a nuclear meltdown.

In the US, president Trump recently declared a “national emergency” to recognise the threat to US computer networks from “foreign adversaries”.

Politically-motivated cyber attacks are becoming increasingly commonplace but unlike traditional warfare between two or more states, cyberwarfare can be launched by groups of individuals. On occasion, the state is actually caught in the crosshairs of competing hacking groups.

Information theory, which was developed by Claude Shannon starting in the late 1940s, deals with questions such as how quickly information can be sent over a noisy communications channel. Both the information carriers (e.g., photons) and the channel (e.g., optical fiber cable) are assumed to be clas…

The more I read about cryonics—i.e. freezing yourself after death—the more I realized it’s something we should all be talking about.

A drug cocktail could be the key.
