The Race to Reveal Antimatter’s Secrets

A laboratory at CERN hosts the only usable source of antiprotons, the proton’s antimatter counterpart. In a high-ceilinged hangar at CERN, six rival experiments are...

How to make AI trustworthy

Autonomous cars concept illustration (stock image). Credit: © folienfeuer / stock.adobe.com One of the biggest impediments to adoption of new technologies is trust in AI. Now, a new tool developed by USC Viterbi Engineering researchers generates automatic indicators if data and predictions generated by AI algorithms are trustworthy. Their research paper, "There Is Hope After…

Scientists create artificial catalysts inspired by living enzymes

Molecular models (stock image). Credit: © shotsstudio / Adobe Stock All living organisms depend on enzymes -- molecules that speed up biochemical reactions that are essential for life. Scientists have spent decades trying to create artificial enzymes capable of cranking out important chemicals and fuels at an industrial scale with performance rivaling their natural counterparts.…

How can robots land like birds?

Credit: © ssmalomuzh / Adobe Stock Researchers at Oregon State University are paving the way toward greater safety for coastal residents and infrastructure by developing a better means of modeling the destructive force of tsunami waves. Rare but potentially devastating, tsunamis can cause huge damage to coastal infrastructure, with…

Scurrying roaches help researchers steady staggering robots

Cockroach (stock image). Credit: © vitali_chesnokov / Adobe Stock Ew, a cockroach! But it zips off before the swatter appears. Now, researchers have leveraged the bug's superb scurrying skills to create a cleverly simple method to assess and improve locomotion in robots. Normally, tedious modeling of mechanics, electronics, and information science is required to understand…

Robots need a new philosophy to get a grip

Robotic arm (stock image). Credit: © Nay / Adobe Stock Robots need to know the reason why they are doing a job if they are to effectively and safely work alongside people in the near future. In simple terms, this means machines need to understand motivethe way humans do, and not just perform tasks blindly,…

First-ever successful mind-controlled robotic arm without brain implants

Cursor on computer screen (stock image). Credit: © Mihai Simonia / Adobe Stock A team of researchers from Carnegie Mellon University, in collaboration with the University of Minnesota, has made a breakthrough in the field of noninvasive robotic device control. Using a noninvasive brain-computer interface (BCI), researchers have developed the first-ever successful mind-controlled robotic arm…

Beyond 1 and 0: Engineers boost potential for creating successor to...

Binary data concept. Credit: © gonin / Adobe Stock Computers and similar electronic devices have gotten faster and smaller over the decades as computer-chip makers have learned how to shrink individual transistors, the tiny electrical switches that convey digital information. Scientists' pursuit of the smallest possible transistor has allowed more of them to be packed…

Why are gels elastic?

However, until now, scientists…

Smallest pixels ever created could light up color-changing buildings

Pixels (stock illustration). Credit: © kinako / Adobe Stock The smallest pixels yet created -- a million times smaller than those in smartphones, made by trapping particles of light under tiny rocks of gold -- could be used for new types of large-scale flexible displays, big enough to cover entire buildings. The colour pixels, developed…

New state of matter: Elements can be solid and liquid at...

Potassium chemical symbol (stock image). Credit: © Aleksander / Adobe Stock Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously. Applying high pressures and temperatures to potassium -- a simple metal -- creates a state in which most of the element's atoms form a…

Fracking: Earthquakes are triggered well beyond fluid injection zones

USGS map highlights earthquake risk zones. Blue boxes indicate areas of high activity of human-caused earthquake due to deep bore fluid injection. Credit: USGS Using data from field experiments and modeling of ground faults, researchers at Tufts University have discovered that the practice of subsurface fluid injection used in 'fracking' and wastewater disposal for oil…

New technique could pave the way for simple color tuning of...

The top row is a GaN:Eu LED, which can be tuned from red-yellow due to red and green light mixing from different Eu states. The middle and bottom rows are of a GaN:Eu LED with additionally added Si/Mg, which adds blue emission. Each picture is under a different current injection/filtering condition.

Artificial mother-of-pearl created using bacteria

This abalone shell is a natural form of nacre -- also known as mother-of-pearl -- an exceptionally tough material found in shells and pearls. Rochester biologists have developed an innovative method for creating nacre in the lab -- and maybe on the moon. Credit: University of Rochester photo / J. Adam Fenster The strongest synthetic…

Engineers make injectable tissues a reality

Doctoral student Mohamed Gamal uses a newly developed cell encapsulation device. Credit: Nathan Skolski, UBC Okanagan A simple injection that can help regrow damaged tissue has long been the dream of physicians and patients alike. A new study from researchers at UBC Okanagan moves that dream closer to reality with a device that makes encapsulating…

Snake-inspired robot slithers even better than predecessor

The robot is made using kirigami -- a Japanese paper craft that relies on cuts to change the properties of a material. As the robot stretches, the kirigami surface "pops up" into a 3D-textured surface, which grips the ground just like snake skin.
