| First evidence of snake-like venom glands found in amphibians Posted: 03 Jul 2020 11:12 AM PDT Caecilians are limbless amphibians that can be easily mistaken for snakes. Though caecilians are only distantly related to their reptilian cousins, researchers describe specialized glands found along the teeth of the ringed caecilian (Siphonops annulatus), which have the same biological origin and possibly similar function to the venom glands of snakes. As such, caecilians may represent the oldest land-dwelling vertebrate animal with oral venom glands. |
| Scientific 'red flag' reveals new clues about our galaxy Posted: 03 Jul 2020 11:12 AM PDT By determining how much energy permeates the center of the Milky Way, researchers have moved closer to understanding the power behind our galaxy. |
| Sneaky salmonella finds a backdoor into plants Posted: 30 Jun 2020 12:04 PM PDT Researchers have discovered that bacteria such as salmonella, E. coli and listeria have a backdoor to take advantage of humans' reliance on leafy greens for a healthy diet. They found that wild strains of salmonella are delivering foodborne illnesses by circumventing a plant's immune defense system, getting into the leaves of lettuce by opening up the plant's tiny breathing pores. |
| Buzzing to rebuild broken bone Posted: 30 Jun 2020 08:15 AM PDT Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, engineers report. Although minor bone breaks usually heal on their own, large fractures with shattered or missing chunks of bone are more difficult to repair. A biocompatible, dissolving polymer device can mimic the body's natural electrical field and help the cells regenerate. |
