New aircraft-scheduling models may ease air travel frustrations

Flight schedules that allow for a little carefully designed wiggle room could prevent the frustration of cascading airport delays and cancellations. By focusing on the early phases of flight schedule planning and delays at various scales, researchers have developed models to help create schedules that are less susceptible to delays and easier to fix once disrupted.

3-D printed sugar scaffolds offer sweet solution for tissue engineering, device manufacturing

University of Illinois engineers built a 3-D printer that offers a sweet solution to making detailed structures that commercial 3-D printers can’t: Rather than a layer-upon-layer solid shell, it produces a delicate network of thin ribbons of hardened isomalt, the type of sugar alcohol used to make throat lozenges. The water-soluble, biodegradable glassy sugar structures have multiple applications in biomedical engineering, cancer research and device manufacturing.

Engineers on a roll toward smaller, more efficient radio frequency transformers

The future of electronic devices lies partly within the “internet of things” – the network of devices, vehicles and appliances embedded within electronics to enable connectivity and data exchange. University of Illinois engineers are helping realize this future by minimizing the size of one notoriously large element of integrated circuits used for wireless communication – the transformer.

Elastic microspheres expand understanding of embryonic development and cancer cells

A new technique that uses tiny elastic balls filled with fluorescent nanoparticles aims to expand the understanding of the mechanical forces that exist between cells, researchers report. A University of Illinois-led team has demonstrated the quantification of 3-D forces within cells living in petri dishes as well as live specimens. This research may unlock some of the mysteries related to embryonic development and cancer stem cells, i.e., tumor-repopulating cells.

New polymer manufacturing process saves 10 orders of magnitude of energy

Makers of cars, planes, buses – anything that needs strong, lightweight and heat resistant parts – are poised to benefit from a new manufacturing process that requires only a quick touch from a small heat source to send a cascading hardening wave through a polymer. Researchers at the University of Illinois have developed a new polymer-curing process that could reduce the cost, time and energy needed, compared with the current manufacturing process.

New CRISPR technology ‘knocks out’ yeast genes with single-point precision

The CRISPR-Cas9 system has given researchers the power to precisely edit selected genes. Now, researchers have used it to develop a technology that can target any gene in the yeast Saccharomyces cerevisiae and turn it off by deleting single letters from its DNA sequence.

Prosthetic arms can provide controlled sensory feedback, study finds

Losing an arm doesn’t have to mean losing all sense of touch, thanks to prosthetic arms that stimulate nerves with mild electrical feedback. University of Illinois researchers have developed a control algorithm that regulates the current so a prosthetics user feels steady sensation, even when the electrodes begin to peel off or when sweat builds up. 

Laser light show machine teaches students math, computer programming

Laser light shows are no longer just the stage dressing for rock concerts. They’re also a fun way for local middle school students to learn the fundamentals of mathematics from educators and scientists at the University of Illinois.

Illinois architecture professor designs transformable, adaptive structures

University of Illinois architecture professor Sudarshan Krishnan designs lightweight and transformable structures that can expand and collapse to adapt to a user’s needs.

New camera gives surgeons a butterfly’s-eye view of cancer

Cancer lurking in tissue could be more easily found when looking through a butterfly’s eye.
