Do we know what we want in a romantic partner? No more than a random stranger would — ScienceDaily

We all can describe our ideal partner. Perhaps they are funny, attractive and inquisitive. Or maybe they are down-to-earth, intelligent and thoughtful. But do we actually have special insight into ourselves, or are we just describing positive qualities that everyone likes? New research coming out of the University of California, Davis, suggests that people’s ideal partner preferences do not reflect any unique personal insight. The paper, “Negligible Evidence That People Desire Partners Who Uniquely Fit Their Ideals,” was published last…

Retrie: Haskell refactoring made easy

What’s new: We’ve open-sourced Retrie, a code refactoring tool for Haskell that makes codemodding faster, easier, and safer. Using Retrie, developers can efficiently rewrite large codebases (exceeding 1 million lines), express rewrites as equations in Haskell syntax instead of regular expressions, and avoid large classes of codemodding errors. Retrie’s features include the ability to rewrite expressions, types, and patterns; the ability to script rewrites and add side conditions; and a library for scripting more advanced rewrites. Retrie also respects and…

Single Pair Ethernet Changes Scope of Next-Gen Cabling Systems

For almost a half-century, the development of Ethernet has moved inexorably in one direction—faster. When Robert Metcalfe co-invented it with his team at Xerox Palo Alto in the 1970s, Ethernet had an initial speed of 2.94 megabits/second over coaxial cable. In 1980, the original 10 Mbit/s standard was published with an additional option: twisted pair copper cables. Fast Ethernet (100Mbit/s) debuted in 1995, followed by Gigabit Ethernet in 1998. Today Industrial Ethernet has reached 400 Gbit/s, and true terabit speeds—exceeding…

New sequencing technology will help scientists decipher disease mechanisms — ScienceDaily

New technologies capable of sequencing single molecules in fine detail will help scientists better understand the mechanisms of rare nucleotides thought to play an important role in the progression of some diseases. A review paper, led by a scientist at the University of Birmingham, describes how emerging sequencing technologies will transform our understanding of these molecules, ultimately leading to new drug targets. The paper is published in the journal Trends in Biotechnology. Expression of genes to make protein involves making…

Reverse engineering of 3-D-printed parts by machine learning reveals security vulnerabilities

Credit: NYU Tandon School of Engineering Over the past 30 years, the use of glass and carbon-fiber reinforced composites in aerospace and other high-performance applications has soared along with the broad industrial adoption of composite materials. Key to the strength and versatility of these hybrid, layered materials in high-performance applications is the orientation of fibers in each layer. Recent innovations…

A New 3D Approach to Remote Engineering in the Post-pandemic World

Just one hour of unplanned downtime can cost an organization hundreds of thousands of dollars. But in the post-pandemic world, fixing equipment failures is no longer as simple as flying in an expert to sort things out on the spot. In fact, most aspects of doing business have now become more complex as organizations have suddenly been forced to adapt to new ways of remote working. Conferencing services have taken off as a way for remote teams to collaborate on…

Jellyfish-inspired soft robots can outswim their natural counterparts

Illustration of a soft robot jellyfish. Credit: NC State University Engineering researchers at North Carolina State University and Temple University have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful. “Our previous work focused on making soft robots that were inspired by cheetahs—and while the robots were very fast, they still had a stiff inner spine,” says Jie Yin,…

This Week in PowerBites: EV Drivetrain MOSFETs, Hybrid Aircraft

>> Electronic Design Resources.. >> Library: Article Series.. .. >> Article Series: PowerBites  4th-Gen SiC MOSFETs Boast Ultra-Low On-Resistance, Target EV Drivetrains With an eye on automotive powertrain applications, ROHM announced its fourth-generation AEC-Q101-qualified, 1200-V silicon-carbide (SiC) MOSFETs. They offer exceptionally low on-resistance that can improve the efficiencies of main drive inverters, as well as power supplies in industrial equipment. As electric vehicles (EVs) and plug-in hybrid EVs (PHEVs) face growing expectations to deliver the range and performance of their…

Manufacturing Sets Off Fireworks in June

The International Manufacturing Technology Show is the latest major trade show to close up shop due to the global pandemic. The Association for Manufacturing Technology (AMT), which stages the biannual show in Chicago, said late Monday that the 2020 edition of IMTS has been cancelled after show officials said they could not get assurances from state or city officials that the venue would be cleared to open in time for the September show. “In early May, [Illinois Gov. J.B. Pritzker]…
