Stanford scientists make major breakthrough in regenerative medicine
...ful. If the genetic sequence described in the sea squirt
applies to humans, this study represents a major step for regenerative medicine. The sea squirt
is more closely related to humans than many would expect. It may appear similar to a sea sponge, wor...

Botrylloides leachi. Sea squirts (also called "tunicates" after their tough outer tunic) are widely distributed in shallow coastal waters as colonies of genetically identical individuals called "zooids." To investigate WBR in B. leachi, Rinkevich ...

...sumer." The animal, Diazona angulata , is a sea squirt
a few inches wide that lives in colonies anchored to rocks. It was discovered offshore of the Philippines in 1990 as scientists were looking for species that might lead to useful drugs. From a few specimens, scientists extracted a tiny amount of a to...

out a thick gel of silk solution. (One teaspoonful can make 10,000 webs.) They then use their hind legs as well as their body weight and gravity to elongate the gel into a fine thread. Kojic, who first practiced on silkworms, learned how to extract ...

Velvet worm brains reveal secret sisterhood with spiders
...lt to approach with a pair of forceps because they squirt
out this gluey substance that bungs up one's dissection tools. In the wild they use it to immobilize their prey," Strausfeld said of the 2-inch-long critters. "They're really quite extraordinary." Strausfeld and his colleagues compared the brain ar...
Getting ACL tears to heal themselves

the gel into the wound via two small incisions in the knee. Her team is also trying to enhance the gel to speed the healing process. MORE: Until the 1970s, surgeons tried to repair ACL tears by sewing the ligament ends back together, but the sutur...
