SpaceX’s Starship is powered by methane. Its Falcon 9 runs on highly refined kerosene known as RP-1.

But if a new tweet means anything, SpaceX CEO Elon Musk already has his eyes set on a much higher-tech rocket fuel: antimatter.

In a reply to a post about antimatter rockets — hypothetical spacecraft that would be powered by antimatter — Musk tweeted just two words: “Ultimately, yes.”

When developers deliver software to their clients, they often also provide what is known as a ‘test suite.’ A test suite is a tool that allows users to test software, unveil any bugs it might have and give developers a chance to fix these bugs or other potential issues.

In addition to evaluating software, therefore, developers also need to ascertain the efficacy of a test suite in identifying bugs and errors. One way to run test suite evaluations is via mutation testing, a technique that generates several ‘mutants’ of a program by slightly modifying its original code. While mutation testing tools have proved to be incredibly helpful, most of them cannot be applied to software that is only available in binary code (a way of representing texts or instructions for computers using two symbols, generally ‘0’ and ‘1’).

Researchers at Arizona State University, Worcester Polytechnic Institute and the University of Minnesota have recently developed SN4KE, a framework that can be used to carry out mutation analyses at a binary level. This framework, presented at the Binary Analysis Research (BAR) NDSS symposium ‘21 in February, is a new tool to efficiently test suites for software based on binary codes.

A new type of supply chain attack unveiled last month is targeting more and more companies, with new rounds this week taking aim at Microsoft, Amazon, Slack, Lyft, Zillow, and an unknown number of others. In weeks past, Apple, Microsoft, Tesla, and 32 other companies were targeted by a similar attack that allowed a security researcher to execute unauthorized code inside their networks.

The latest attack against Microsoft was also carried out as a proof-of-concept by a researcher. Attacks targeting Amazon, Slack, Lyft, and Zillow, by contrast, were malicious, but it’s not clear if they succeeded in executing the malware inside their networks. The npm and PyPi open source code repositories, meanwhile, have been flooded with more than 5000 proof-of-concept packages, according to Sonatype, a firm that helps customers secure the applications they develop.

“Given the daily volume of suspicious npm packages being picked up by Sonatype’s automated malware detection systems, we only expect this trend to increase, with adversaries abusing dependency confusion to conduct even more sinister activities,” Sonatype researcher Ax Sharma wrote earlier this week.

Bluetooth sunglasses are a great idea—but these aren’t quite good enough.

Materials capable of performing complex functions in response to changes in the environment could form the basis for exciting new technologies. Think of a capsule implanted in your body that automatically releases antibodies in response to a virus, a surface that releases an antibacterial agent when exposed to dangerous bacteria, a material that adapts its shape when it needs to sustain a particular weight, or clothing that senses and captures toxic contaminants from the air.

Scientists and engineers have already taken the first step toward these types of autonomous materials by developing “active” materials that have the ability to move on their own. Now, researchers at the University of Chicago have taken the next step by showing that the movement in one such active material—liquid crystals—can be harnessed and directed.

This proof-of-concept research, published on February 182021, in the journal Nature Materials, is the result of three years of collaborative work by the groups of Juan de Pablo, Liew Family Professor of Molecular Engineering, and Margaret Gardel, Horace B. Horton Professor of Physics and Molecular Engineering, along with Vincenzo Vitelli, professor of physics, and Aaron Dinner, professor of chemistry.
