Remora fishes have a unique dorsal suction pad that allows them to form robust, reliable, and reversible attachmentto a wide variety of host organisms and marine vessels. Although investigations ofthe suction pad have been performed, the primary force that remoras must resist, namely fluid drag, has received little attention. This work […]
Periodic food shortages are a major challenge faced by organisms in natural habitats. Cave-dwelling animals must withstand long periods of nutrient deprivation, as—in the absence of photosynthesis—caves depend on external energy sources such as seasonal floods1. Here we show that cave-adapted populations of the Mexican tetra, Astyanax mexicanus, have dysregulated blood […]
Mucus is a significant part of the body’s defense mechanism against illness. Because of its benefits to human health, researchers at MIT found a way to create synthetic mucus by replicating the make-up of real mucins. The new synthetic mucus successfully neutralized the bacterial toxin that causes cholera, and this new […]
A group of researchers from the University of London found that the micro-structure finlets on an owl’s feathers can help reduce aircraft noise. With the flow simulation of these finlets, the study shows how they act as thin guide vanes to reduce vortices and drag. Thus having […]
The remora fishes are capable of adhering to a wide variety of natural and artificial marine substrates using a dorsal suction pad. The pad is made of serial parallel pectinated lamellae, which are homologous to the dorsal fin elements of other fishes. Small tooth-like projections of mineralized tissue from the dorsal […]
Dynamic attachment is the key to moving safely and fast in a threedimensional environment. Among lizards, hexapods and arachnids, several lineages have evolved hairy foot pads that can generate strong friction and adhesion on both smooth and rough surfaces. A strongly expressed directionality […]
In small doses, nitrogen can be beneficial and nutritious to coral species. However, excessive nitrogen in the coral’s local environment can do much more harm than good to the coral’s health. Scientists noticed that there were certain nitrogen-scrubbing microbes that may contribute to balancing the levels of nitrogen in some corals’ […]
If you have driven down a dark road, you have often seen glimpses of bright flashes in the middle of the street. These light reflectors or cat’s eyes are used in road marking to allow drivers to safely drive within their lane. English […]
Researchers estimate that hundreds of millions of birds are killed each year due to collisions with glass windows. To reduce bird-window collisions, Arnold Glas looked to Orb weaver spiders who build their webs with ultraviolet (UV) silk. The reflective properties of the UV […]
