Researchers Mark Boslough and Randy Gladstone suggest that entry of ordinary meteoroids can form dark spots similar to those observed by satellites, contradicting a theory of frequent small comet bombardment. Their study provides evidence for the existence of high-altitude plumes generated by meteors.
Researchers have discovered reproductive and hormonal problems in alligators from Lake Okeechobee, similar to those found in the highly polluted Lake Apopka. The study suggests that environmental toxicants can affect thyroid function and growth in animals.
Research suggests that virtual reality's immersive and multisensory features facilitate conceptual and three-dimensional learning of abstract science concepts. The study found that VR microworlds can provide experiential referents and enable students to perceive invisible factors and relationships, leading to improved understanding.
Researchers at Georgia Tech developed a new type of microrelay that can switch large current loads at five volts, setting records for contact resistance and current handling capability. The devices offer cost advantages due to batch production and standard microelectronics processing.
