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...

Whole body regeneration from a blood vessel

... WBR in our closest invertebrate relative, the sea squirt 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 ...

Sea creature's toxin could lead to promising cancer treatment

...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...

MIT engineers probe spiders' polymer art

...and twisting fibers to form thread); instead, they squirt 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

... is developing an arthroscopic approach that would squirt 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...

3,317 and counting (the number of marine species in the Gulf of Maine)

...hat New Englanders call the "steamer, "long-neck," squirt clam," or "belly clam" or simply "the clam" -- is a species formally known as Mya arenaria and commonly known as the soft-shelled clam. It is one of 110 known species of bivalves in the Gulf of Maine region, a class of species that also includes mu...

Insight into our sight: A new view on the evolution of the eye lens

Study shows humans have ability to track odors, much like bloodhounds

...l, were able to tell which nostril was receiving a squirt of scent, but anosmic volunteers could only localize the trigeminal odorants, Sobel said. This shows that humans are able to localize odors through the olfactory nerves alone. "One possible objection is that the experimental set-up, with a mask that ...

Little microbe inside sea squirt makes big splash

...ientists couldn't tell if the bacterium or the sea squirt produced the sought-after patellamides, until now. By searching for patellamide synthesis instructions in genomic sequences, scientists found the bacterium indeed has the necessary genes to produce these potentially important biochemicals, solving th...

The eyes behind it look surprisingly unperturbed. "I sprayed the visor beforehand with rhodamine," Katja Tzschtzsch calmly explains, "It's a pigment w...

The simple truth: Animal development not as complicated as it seems

...neages of three different nematode worms and a sea squirt with those randomly generated by a computer program. They found that the real embryos did not behave like the computer-generated ones, but instead showed that these organisms took fewer "different steps" to fully mature than predicted by chance. In...

Invasive sea squirt alive and well on Georges Bank

Woods Hole, Mass.--The invasive sea squirt that federal and university researchers discovered on Georges Bank a year ago is flourishing in U.S. waters near the U.S.-Canada boundary, a joint research team announced today following a research cruise that concluded last week. Scientists from the...
