How the 'mute' cicada sings

Researchers found that 'mute' cicadas produce sound by banging their forewing costa against the operculum, a newfound mechanism. This discovery expands our understanding of acoustic signaling in cicadas without tymbal organs.

Crocs rocked pre-Amazonian Peru

A new study has uncovered seven different species of crocodiles co-existing in the same place and time, filling gaps in understanding the Amazon's rich biodiversity. The research suggests that a peak in mollusk diversity was correlated with the rise of 'durophagous' crocodiles, which went extinct when the mega-wetlands transformed.

Neighboring birds sing 'out of tune'

Researchers found that neighboring birds sang at significantly different rates than non-neighboring birds, according to a study published in PLOS ONE. Great tits use their songs to signal territory boundaries, and the study suggests that neighborhood structure may shape variation in territorial birdsong.

Study: Listeria pathogen is prevalent, persistent in retail delis

A study by Purdue University researchers found that Listeria monocytogenes bacteria are widespread in retail delis, with 6.8% of samples tested positive before operation and 9.5% during operation over six months. The bacteria can persist in growth niches, posing a risk to vulnerable immune systems. To mitigate this risk, experts recomm...

Astronomers breathe new life into venerable instrument

A team of astronomers successfully restored the Half-wave Spectropolarimeter (HPOL) instrument, allowing it to conduct measurements with improved performance. The upgraded HPOL is now fully operational at the University of Toledo's Ritter Observatory and enables researchers to study variable or transient objects more effectively.

Stopping cancer in its tracks

A team led by Dr. Andrew Craig is developing inhibitory antibodies targeting key signals that cancer cells require for metastasis. The goal is to identify lead antibodies and test their potency in pre-clinical models to develop new immunotherapies for clinical trials.

State performance funding falling short in student retention and degree completion

New research found that state performance funding in Washington State did not increase student retention and degree completion, despite being a model for accountability systems. However, short-term certificate programs showed growth in students earning certificates with little value in the labor market.
