If forensic experts have access to a suspect’s gun, they can compare the microscopic markings from discarded shell casings with those found at a crime scene. Finding and reporting a mismatch can help free the innocent, just as a match can incriminate the guilty. But new research reveals mismatches are more likely than matches to be reported as “inconclusive” in cartridge-case comparisons.
An Iowa State University professor is creating art out of data produced by tree saplings and the environment using sound, light and artificial intelligence. It’s an experimental approach to science and technology that inspires an alternate awareness of the environment in its audience.
Over the last decade, a growing number of companies and organizations have included messages about diversity and inclusion as part of their employee recruitment efforts.
New research shows entrepreneurs in Mexico become a greater target of crime as their businesses grow and become more profitable. The study also found entrepreneurs typically respond to crime in one of three ways: Truncating business growth, relocating or shutting down their operation.
New research shows crowdsourcing contests for marketing content are associated with high returns — but also high risks.
Many Ukrainian farmers are raising hogs for the first time, converting cheap grain into needed meat. An Iowa State University swine health expert is helping Ukrainian farmers safely navigate the war-driven pivot to pork with a series of online workshops.
With wireless infrastructure installed in and around Ames, Iowa, the $16 million ARA Wireless Living Lab for Smart and Connected Rural Communities is moving to a public testing phase. The progress will be celebrated with technical presentations and field trips during a launch event Sept. 6-8 on the Iowa State University campus.
Using "experiential" descriptions and more photos on Zillow can boost offers and sale prices, especially for homes valued significantly higher or lower than the neighborhood average, according to a new study.
The NFL adopted the Rooney Rule 20 years ago as part of an effort to address racial disparity in top coaching positions. But new research suggests the gap will persist unless it’s closed with lower-level coaching staff.
Chemists are building nanospheres that act as super enzymes to break down the plant fibers in biomass such as crop residues. The new catalysts could make biomass a practical source of sugars that can be converted into fuels and chemicals.
Midwest researchers are working together to develop and promote a new green fertilizer that would reduce greenhouse gas emissions. The $4 million project is supported by a National Science Foundation program designed to build scientific infrastructure and capabilities across the country.
A new study finds unsupervised, online exams can provide a valid and reliable assessment of student learning, but instructors should be aware of potential weak spots.
Iowa State's Electric Power Research Center is helping industry study ways to add renewables to the power grid as the country makes plans to electrify the economy.
Iowa State University researchers found college students who tried to cut their social media use to 30 minutes per day scored significantly lower for anxiety, depression, loneliness and fear of missing out at the end of the two-week experiment and when compared to the control group.
A new paper explores how the Kickapoo Indian Medicine Company pushed stereotypes and claimed authority on Indigenous culture in the 1800s to sell products. It also highlights several ironies. As “Indian remedies” became mainstream, the U.S. government rolled out policies to restrict Indigenous healing and spiritual practices, which are often intertwined.
Service members deployed to conflict zones may be at greater risk of developing post-traumatic stress disorder if they were abused in childhood. This, along with other findings from a new study, help clarify how adverse experiences early in life can make people more vulnerable to trauma later on.
After pioneering a system to improve swine health by collecting and publicizing pathogen testing results from large public veterinary laboratories across the Midwest, a team led by faculty from Iowa State University’s College of Veterinary Medicine is planning to bore even deeper to glean more insight from the vast data set.
A new collection of essays from a dozen Iowa State University faculty underscores how all of us can play a role in cultivating a more peaceful world. The authors demonstrate this by drawing from their own disciplines – agriculture, architecture, business, education, engineering, history, music, nutrition and food systems and philosophy.
Co-authors of a new paper argue that negative emotions – if leveraged in the right way – can help teams adapt. They make their case by dissecting scenes from three blockbuster movies, each of which represent a different type of team and threat.
Iowa State University engineers are developing advanced tools for cell manufacturing that could improve the cost and availability of therapeutic cells capable of fighting diseases such as cancers, heart disease, lupus and other autoimmune diseases.
New research suggests investigative law enforcement officers have a harder time focusing on their work and managing their emotions on days when they're more fatigued. They also face greater difficulty establishing rapport with interviewees.
The National Science Foundation's program to build research capacity across the country has awarded a $20 million grant to support Iowa researchers working to make the state a leader in advanced biomanufacturing. The researchers will use microbes to produce plastics for 3D printing, fibers for flexible and rigid materials and proteins for medical diagnostics and therapeutics.
An interdisciplinary team of Iowa State researchers find women experience cybersickness with virtual reality headsets more often than men. Their ongoing work explores why this difference exists and methods to help people adapt.
Virtual fitting rooms can cut down on returns and nudge hesitant online shoppers to click the checkout button. But findings from a recently published study indicate the technology could backfire on retailers if they assume consumer interactions are uniformly positive. The authors provide several recommendations based on their research.
Researchers are designing nanoparticles to treat inflammatory bowel diseases such as such as Chron’s disease and ulcerative colitis. Key innovations are the design of self-assembling nanoparticles that carry drugs and naturally target inflamed colons. The nanoparticles could deliver relief to more than 3 million Americans who suffer from the diseases.
The recent discovery of a complete sabertooth cat skull from southwest Iowa provides the first evidence of this animal in the state. It also offers clues about an iconic Ice Age predator before the species went extinct roughly 12-13,000 years ago. Researchers believe the skull belonged to a subadult male that may have preyed on giant ground sloths.
Inflation took a bigger bite of rural household budgets throughout much of 2022, but its effects were similar in rural and urban areas by the end of the year, according to a report by an Iowa State University professor. Two years of rising prices have shrunk discretionary income in rural households to less than $500 a month.
A world-renowned criminologist at Iowa State lays out evidence in a new book that Ted Bundy’s criminal career was far lengthier and deadlier than the official record. He says the story of Bundy reflects the unsolved murder epidemic in the U.S. and offers solutions to reduce the backlog of cold cases.
A new study compares the communication strategies of NGOs working on migration issues in two neighboring countries, Turkey and Bulgaria. The research findings highlight how the specific political and cultural context of a country affects an organization’s messaging.
