Can echolocation help those with vision loss?

A 10-week training program showed that both sighted and blind participants improved on echolocation tasks, with some even performing better than expert echolocators. The study's findings suggest that click-based echolocation can be a valuable tool for people with vision loss or progressive degenerative eye conditions.

Anyone can get super-hearing

Researchers at Aalto University developed a new audio technique that allows people to track bats in flight and localise sources of ultrasonic sound, enabling super-hearing. The device records ultrasound using microphones on a small sphere, pitch-shifts the signal, and plays it back through headphones.

Research suggests BMI may not be best obesity indicator to assess risk for lung cancer

A new study published in the Journal of Thoracic Oncology found that using traditional methods like BMI can misclassify obesity as a non-risk factor for lung cancer. The researchers measured visceral fat index through CT scans and found a clear correlation between central obesity and poor lung cancer outcomes.

Male piglets less resilient to stress when moms get sick during pregnancy

A study from the University of Illinois found that male piglets are more susceptible to neurodevelopmental and neurological anomalies when their mothers are infected with PRRSV during pregnancy. The researchers also discovered changes in gene expression associated with autism spectrum disorder, schizophrenia spectrum disorder, and neur...

Luring bacteria into a trap

Researchers at ETH Zurich developed a vaccine that guides bacteria's evolution to make them a weaker pathogen, rather than trying to kill them. The combination vaccine was shown to be more effective in preventing Salmonella infections than existing vaccines.
