Researchers discovered that certain male songbirds like stripe-backed wrens learn calls only from their fathers, while females exclusively learn from their mothers. This unique vocal instruction system reflects sex and kinship in birds' communication, providing insights into avian behavior and social dynamics.

A Cornell University robot made from plastic Tinkertoy parts has been shown to perform repeatable, chattering, human-like stable steps without falling over on a gentle slope. The robot's design provides new insights into the mechanics of walking and may have implications for designing better powered and controlled biped robots.

Researchers found that choline supplementation during pregnancy led to increased memory capability in offspring, as brain circuits were primed to learn and retain new information. This finding has implications for pregnant women and their children, potentially leading to the development of dietary supplements to enhance memory function.

Cornell University researchers have developed simple but effective means to detect harmful bacteria using nanofabrication and biology. The new biosensors can be read using a laser beam and provide an instant reading of bacterial contamination, making them ideal for use in food production lines or other sensitive areas.

Researchers at the University of Pennsylvania School of Medicine found that delivering pain medication to patients before surgery reduces post-operative pain long after. The study, which involved 90 men undergoing radical prostatectomies, showed significant pain reduction in patients who received preemptive analgesia.

Researchers confirm that premature and low-birth weight infants should receive their immunizations at the same ages recommended for healthy, full-term babies. The study found that even the least immunologically mature preterm infants had adequate immune responses that lasted until age three to four.
