Genetic sequencing uncovers unexpected source of pathogens in floodwaters
CHAMPAIGN, Ill. — Researchers report in the journal Geohealth that local rivers and streams were the source of the Salmonella enterica contamination along coastal North Carolina after Hurricane Florence in 2018 – not the previously suspected high number of pig farms in the region. These findings have critical implications for controlling the spread of disease […]
Why are global carbon emissions starting to increase again?
On Dec. 5, the Global Carbon Project published the Global Carbon Budget 2023, giving world leaders access to data on atmospheric carbon concentrations, emissions and trends. University of Illinois Urbana-Champaign atmospheric scientist Atul Jain is among the many scientists worldwide who contributed data to the report. Jain talked about the current state of the carbon […]
In TED Talk, Long describes three photosynthetic changes that boost crop yields
CHAMPAIGN, Ill. — In a newly released TED Talk, Stephen Long, a University of Illinois Urbana-Champaign professor of plant biology and crop sciences, detailed his and his colleagues’ efforts to boost photosynthesis in crop plants. He described three interventions, each of which increased crop yields by 20% or more. Long is the director of the […]
Researchers engineer a material that can perform different tasks depending on temperature
CHAMPAIGN, Ill. — Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment. The new study conducted by University of Illinois Urbana-Champaign civil […]
Researchers identify unexpected twist while developing new polymer-based semiconductors
CHAMPAIGN, Ill. — A new study led by chemists at the University of Illinois Urbana-Champaign brings fresh insight into the development of semiconductor materials that can do things their traditional silicon counterparts cannot – harness the power of chirality, a non-superimposable mirror image. Chirality is one of nature’s strategies used to build complexity into structures, […]
Science historian Naomi Oreskes to talk about how free market ideology blocks climate action
CHAMPAIGN, Ill. — Climate change is a crisis that has resulted from the massive failure of the energy market, and free market ideology and the rejection of government’s role in correcting such market failures has stymied efforts to address it, says scientist and historian Naomi Oreskes. A leader in examining the efforts to undermine the […]
Researchers propose a unified, scalable framework to measure agricultural greenhouse gas emissions
CHAMPAIGN, Ill. — Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, a team led by scientists at the University of Illinois Urbana-Champaign proposed a supercomputing solution to help measure individual farm field-level greenhouse gas emissions. Although locally […]
Study: YouTube did not actively direct users toward anti-vaccine content during COVID-19
CHAMPAIGN, Ill. — New research led by data science experts at the University of Illinois Urbana-Champaign and United Nations Global Pulse found that there is no strong evidence that YouTube promoted anti-vaccine sentiment during the COVID-19 pandemic. The study, published in the Journal of Medical Internet Research, performed an algorithmic audit to examine if YouTube’s recommendation […]
What prompted tropical cyclone Hilary’s unusual path?
Hilary was the first tropical storm to hit California in 84 years. Atmospheric sciences professor Deanna Hence spoke with News Bureau physical sciences editor Lois Yoksoulian about what made this storm unique and if the Southwest U.S. should expect more like it in the future. Why don’t we usually see tropical cyclones along the western coast of the U.S.? One of […]
Fast, automated, affordable test for cement durability
CHAMPAIGN, Ill. — Engineers at the University of Illinois Urbana-Champaign have developed a new test that can predict the durability of cement in seconds to minutes – rather than the hours it takes using current methods. The test measures the behavior of water droplets on cement surfaces using computer vision on a device that costs […]
Displays controlled by flexible fins and liquid droplets more versatile, efficient than LED screens
CHAMPAIGN, Ill. — Flexible displays that can change color, convey information and even send veiled messages via infrared radiation are now possible, thanks to new research from the University of Illinois Urbana-Champaign. Engineers inspired by the morphing skins of animals like chameleons and octopuses have developed capillary-controlled robotic flapping fins to create switchable optical and […]
What is the state of underwater geolocation technology?
CHAMPAIGN, Ill. — The loss of OceanGate’s Titan submersible this week has triggered questions about how underwater craft navigate and how these vehicles can improve their geolocation abilities. Electrical and computer engineering professor Viktor Gruev spoke with News Bureau physical sciences editor Lois Yoksoulian about the current state of the science behind underwater geolocation, and […]
