Master gene controls healing of skin in fruit flies and mammals

...ir genes in the cells surrounding an injury in the cuticle of a fly embryo. These wound repair genes then reg... Melbourne, Australia report that, although insect cuticle and the outer layer of mammal skin are very different chemically, the grainyhead gene is also essent...

Otter adaptations: How do otters remain sleek and warm

...eptional insulation abilities. They found that the cuticle surface structure of the underhairs and base of the less-abundant guard hairs are distinctively shaped to interlock, with wedge-shaped fins or petals fitting into wedge-shaped grooves between fins of adjacent hairs. Weisel and colleagues report their...

Scientists find a maturity gene in fly

...age larva. At 48 hours, the larva molts ?sheds the cuticle that forms its external or exoskeleton ?and becomes a second-stage larva. The larva molts again at 72 hours to become a third-stage larva. At 120 hours ?five days after the egg was laid ?the larva enters metamorphosis and becomes a "prepupa" for 12 h...

Newly recognized gene mutation may reduce seeds, resurrect plants

...be revealed lipid associated with formation of the cuticle that coats plant surfaces may signal whether a seed develops to maturity or is aborted early due to a defective embryo. "This is interesting because in crop production a number of plants have a problem of reduced yield due to seed or fruit abortion,...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

...lved in the hardening of a beetle's exoskeleton or cuticle could lead not only to better pest control, but al...d that by knocking out an enzyme called laccase-2, cuticle tanning, the process of hardening and pigmentation, can be prevented in the red flour beetle, Tribol...

Nanosecond-scale release of stinging jellyfish nematocysts

...d by some bullets, and sufficient to penetrate the cuticle of crustacean prey. The researchers propose that the high speed of discharge is caused by the release of energy stored in the stretched configuration of the collagen-polymer of the nematocyst capsule wall. This ingenious solution allows the cellular ...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

... the tank ?pieces of earthworm, small fish, insect cuticle and blobs of wax and silicon ?and observed the moles' behavior. He saw that, when the moles approached one of these targets, they would blow bubbles that came into contact with the target's surface and then were sucked back into the nostrils. "Beca...
