Rapid Variation in Dog Breeds Is 'Regulated,' Not 'Evolved'
Almost all new dog breeds have been established in the last few hundred years. Due to this fast genetic diversification, researchers have been investigating how “descent with modification” occurred so quickly in the dog genome.
Slime Networks Are Better Organized than Railway Systems
What do the Tokyo railway system and slime mold have in common?
Answer: They both employ optimized networks. Researchers found that slime mold growth algorithms are so well-designed that they could be copied and used to improve computer and communication networks.
Bee Landing Strategy May Lead to Better Aircraft
Researchers recently looked into the life of bees and found something of interest to all fliers: bees never crash, even when they land on an upside-down surface. Their efficient landings show that current landing techniques for aircraft and spacecraft are overly complicated. Aircraft designers could learn a lot from a bee.
Is There Evolution in the Congo River?
A recent narrative-style article in Smithsonian magazine highlighted research in the largely unexplored Congo River in central Africa, where researchers have identified new fish species. The researchers preliminarily confirmed that strong currents in deep waters had isolated the breeding populations of certain fishes, including the bottom-feeding elephant fish.
