Scientists never would have expected the Amazon River — surging with with more runoff and sediment than any other river in the world — to hold an ecosystem as fragile as a coral reef. But, an international team including scientists from the University of Georgia and the Federal University of Rio de Janeiro found a huge 3,600-square-mile reef system just below the Amazon’s muddy waters.
Scientists have discovered the largest species that has the ability to regrow limbs. According to Business Insider, it's the alligator. Like lizards, young American gators can regrow their tails up to 9 inches. Prof. Kenro Kusumi is a co-senior study author and the director of Arizona State University's School of Life Sciences. Kusumi began studying gator regrowth after receiving a package in the mail that contained a deformed alligator tail in a pickle jar with ethanol. The tail was discolored, forked, and the scales were smaller than normal. Kusumi realized that the tail looked like it had been regrown.
The late, great French biologist Louis Pasteur once said, 'Chance favors the prepared mind.' A group of Dutch cancer scientists says they've discovered a pair of salivary glands that absolutely no one had ever noticed before. CNN reports the glands are hidden away in the skull, where the nasal cavity and the throat meet. The cancer researchers first came across the body part during a scan designed to look for tumorous growths. The 'unknown entity' cannot be seen on X-rays, or in ultrasound, MRI scans, or PET scans. Rather, the glands can only be seen in a new, highly advanced type of scan called PSMA PET/CT The scientists, from the Netherlands Cancer Institute, propose naming them 'tubarial glands.'
