Large, crystalline lipid scaffolds bring new possibilities to protein, drug research

Proteins and drugs are often attached to lipids to promote crystallization or ensure delivery to targeted tissues within the body, but only the smallest proteins and molecules fit within these fat structures. A new study reveals a lipid structure that can support much larger proteins and molecules than before, potentially increasing the variety of drugs that can be attached to these fat molecules.

Tiny aquariums put nanoparticle self-assembly on display

Seeing is believing when it comes to nanoparticle self-assembly. A team of University of Illinois engineers is observing the interactions of colloidal gold nanoparticles inside tiny aquariumlike sample containers to gain more control over the self-assembly process of engineered materials.

Click beetles inspire design of self-righting robots

Robots perform many tasks that humans can’t or don’t want to perform, getting around on intricately designed wheels and limbs. If they tip over, however, they are rendered almost useless. A team of University of Illinois mechanical engineers and entomologists are looking to click beetles, who can right themselves without the use of their legs, to solve this robotics challenge.

Changes in nonextreme precipitation may have not-so-subtle consequences

Major floods and droughts receive a lot of attention in the context of climate change, but University of Illinois researchers analyzed over five decades of precipitation data from North America to find that changes in nonextreme precipitation are more significant than previously realized and larger than those in extreme precipitation. These changes can have a strong effect on ecosystems, agriculture, infrastructure design and resource management, and point to a need to examine precipitation in a more nuanced, multifaceted way.

Congressional redistricting less contentious when resolved using computer algorithm

Concerns that the process of U.S. congressional redistricting may be politically biased have fueled many debates, but a team of University of Illinois computer scientists and engineers has developed a new computer algorithm that may make the task easier for state legislatures and fairer for their constituents.

Study: Biomarkers as predictive of sepsis as lengthy patient monitoring

One measurement of key biomarkers in blood that characterize sepsis can give physicians as much information as hours of monitoring symptoms, a new study found.

Researchers develop dynamic templates critical to printable electronics technology

When it comes to efficiency, sometimes it helps to look to Mother Nature for advice – even in technology as advanced as printable, flexible electronics.

Researchers at the University of Illinois have developed bio-inspired dynamic templates used to manufacture organic semiconductor materials that produce printable electronics. It uses a process similar to biomineralization – the way that bones and teeth form. This technique is also eco-friendly compared with how conventional electronics are made, which gives the researchers the chance to return the favor to nature.  

Engineers find way to evaluate green roofs

Green infrastructure is an attractive concept, but there is concern surrounding its effectiveness. Researchers at the University of Illinois at Urbana-Champaign are using a mathematical technique traditionally used in earthquake engineering to determine how well green infrastructure works and to communicate with urban planners, policymakers and developers.

Quick test finds signs of sepsis in a single drop of blood

A new portable device can quickly find markers of deadly, unpredictable sepsis infection from a single drop of blood.

Corn better used as food than biofuel, study finds

Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.
