• Researchers have discovered that a compound in the mucus found on the back of a frog can cause flu virus particles to explode.
• If they can harness this compound, called urumin, they may be able to create a universal flu vaccine.

A compound in the mucus found on the oozy backs of a South Indian frog — known locally as a germ killer — can cause flu virus particles to explode. Researchers at Emory University have discovered that the compound, a peptide they’ve called urumin, is potent, yet precise, and capable of destroying an entire class of flu viruses while other cells and even other viruses emerge unscathed. Unlike other frog-based compounds, urumin is uniquely nontoxic, another unusual feature that makes it more promising from a therapeutic standpoint.

Researchers have developed an artificial womb to sustain the life of premature babies. That womb just proved successful in animal testing for the first time. This advance could radically transform the lives of millions of premature infants around the world.

The wombs look like nothing too spectacular. They appear more like oversized plastic bags with tubes and fluids rather than the Huxleyan tube babies of science fiction. However, eight of these external womb Biobags held a fetal lamb. During the growth, the lambs developed as their brain, lungs, and other vital organs grew. They grew wool. They even moved about and twitched. A few of the lambs have now grown into adulthood.

Researchers are perfecting technology that sniffs out signs of disease in breath, blood and urine.
