University of Illinois researchers have developed heat-triggered self-destructing electronic devices, a step toward greatly reducing electronic waste and boosting sustainability in device manufacturing. They also developed a radio-controlled trigger that could remotely activate self-destruction on demand.
Dolphins found stranded on Gulf of Mexico beaches following the 2010 Deepwater Horizon oil spill were much more likely to have severe lung and adrenal gland damage “consistent with petroleum product exposure” than dolphins stranded elsewhere and prior to the spill, researchers report. One in five dolphins from the spill zone also had primary bacterial pneumonia.
A study of older adults at risk of late-onset Alzheimer’s disease found that those who consumed more omega-3 fatty acids did better than their peers on tests of cognitive flexibility – the ability to efficiently switch between tasks – and had a bigger anterior cingulate cortex, a brain region known to contribute to cognitive flexibility.
Pakpoom Buabthong, a senior in physics, displays the Deployer cellphone app, which enables users to access and share animated educational videos created by Scientific Animations without Borders. Pictured with Buabthong are SAWBO co-founders Julia Bello-Bravo and Barry Pittendrigh.
A new study offers insights into the genetic changes that accompany social complexity in bees, including honey bees. Carl R. Woese Institute for Genomic Biology faculty members Saurabh Sinha, a professor of computer science; Gene Robinson, a professor of entomology and IGB director; and an international consortium of 52 scientists used comparative genomics to discover that the evolution of bee society is associated with increases in the complexity of gene regulation.
Some species of trap-jaw ants use their spring-loaded mandibles to hurl themselves out of harm’s way when an ant-trapping predator stalks, researchers report in the journal PLOS ONE. This dramatic maneuver doubles the ants’ survival when other escape methods fail, the researchers found.
