The antibiotics market is forecast to reach more than $50 billion by 2025, according to an Oct. However, in experiments on mice, the altered venom was able to keep 80% of the animals alive after exposure to normally fatal strains of E. The venom from the wasps is highly toxic with an ability to destroy red blood cells and trigger allergic reactions. "We think that venom-derived molecules such as the ones we engineered in this study are going to be a valuable source of new antibiotics." "New antibiotics are urgently needed to treat the ever-increasing number of drug-resistant infections and venoms are an untapped source of novel potential drugs," lead scientist César de la Fuente said. Using toxic proteins found in the Korean yellow-jacket wasp, the researchers were able to separate molecules and alter them so that the venom can kill bacteria without harming human cells. Scientists at the University of Pennsylvania have developed a bacteria-killing substance from the venom in wasps that could potentially serve in the fight against antibiotic-resistant infections. The scientists are looking to make the hydrogel even more sensitive to temperature changes to further control the suction. The team created a material made of a temperature-sensitive substance called a hydrogel that, when heated, would expand to form suction with other materials, allowing it to pick them up without causing harm the way normal sticky surfaces might. "However, handling these living substances remains a grand challenge because they are fragile and easily crumple when picking them up from the culture media." "A crucial aspect of tissue transplantation surgery, such as corneal tissue transplantation surgery, is surgical gripping and safe transplantation of soft tissues," lead researcher Hyunjoon Kong said. The same method can be used to create sheets of cells or electronics that can aid in wound healing, regenerative medicine and biosensing. The group of scientists took inspiration from the octopus's ability to pick up various materials using small pressure changes in the suction cups on its tentacles. Researchers at the University of Illinois have turned to an unlikely source to create material used in surgery and wound healing: the suckers that line the tentacles of an octopus. Scientists are researching octopus tentacles to possibly develop new surgical tools.
