America’s last-mile delivery divide

A recent study by Iowa State University researchers found that Americans' use of home delivery continues to be split sharply along geographic lines. Urban shoppers are more likely to rely on home delivery than rural households, driven by factors such as traffic congestion and limited parking in cities.

For autonomous robots, not all rules are equal

A new rulebooks framework developed by Iowa State University researchers provides a principled way for autonomous systems to rank and reconcile competing goals. The framework avoids the issues of blending weighted trade-offs, allowing systems to clearly define which rules come first and choose the least harmful option.

Tired minds, unreliable evidence

Sleep deprivation can weaken eyewitness recall, reduce autobiographical detail, and increase susceptibility to misinformation in legal proceedings. This can lead to false confessions and wrongful convictions, as exhausted individuals may prioritize short-term relief over long-term consequences.

Are we giving AI a pulse through language?

A study by Iowa State University researchers found that anthropomorphizing language, such as using mental verbs like 'think' or 'know', is less common in news writing than expected. When used, these words often describe what AI requires to function, rather than attributing human-like qualities to the system. The research team identifie...

Soil carbon decomposition varies vastly, holding implications for climate models

A new study found that the rate of organic carbon decomposition in soil samples collected across the US differed by up to tenfold, with factors like fungi and iron levels strongly associated with variation. This could improve the accuracy of soil carbon feedback estimates in climate models, leading to more refined projections.

In chromosome of key biotech bacterium, different setups bring different strengths

Researchers found that Agrobacterium's virulence is more effective in its natural two-chromosome state, but it grows faster and handles stress better when fused into a single chromosome. This study opens the door for optimizing its use as a crop improvement tool or devising new ways to protect crops vulnerable to crown galls.

Iowa State researchers find key factor linking longer maturation to longer life in fruit flies

A recent study by Iowa State University researchers found that fruit flies missing a crucial developmental hormone, PTTH, live up to 30% longer due to reduced inflammaging. The connection between developmental timing and lifespan in fruit flies could be a useful model for studying human longevity.

Disrupting ‘communication’ with plants could limit soybean cyst nematode infections

A study co-authored by an Iowa State University professor identified a single protein that triggers chemical signals called effectors in cyst nematodes, which hijack plant cells. Disrupting this protein could severely reduce nematode infections, making it a powerful method for reducing crop damage.

Diversified cropping systems boost nitrogen supply but not soil carbon, study finds

A new study has found that diversified cropping systems can increase nitrogen supply in the soil, but do not lead to increased soil carbon levels. The study, published in Nature Sustainability, used stable carbon isotopes to analyze soil core emissions and found that decomposition rates were higher in longer rotations.

Growing soybeans has a surprisingly significant emissions footprint, but it’s ripe for reduction

A new study by Iowa State University researchers finds that nearly half of soybean-related emissions come from the natural processes in soil, which can be mitigated through strategies like planting winter cover crops and adjusting planting schedules. These solutions have been found to reduce emissions by one-third while increasing yields.

Pausing biological clock could give boost to lab-produced blood stem cells

Researchers at Iowa State University have discovered a potential breakthrough in producing lab-grown blood stem cells by pausing the initial activation of inflammatory signals. This allows for the production of hundreds of functional stem cells, which could replace bone marrow transplants for blood disorders such as leukemia and anemia.
