The realm of colorectal cancer screening recently has expanded in an unlikely direction; namely, the sense of smell. Researchers at Kyushu University in Fukuoka, Japan recently have shown that a dog can accurately detect CRC based on patient breath and stool samples. Their results, which are published in Gut, the medical journal affiliated with the British Society of Gastroenterology, showed a sensitivity of 0.91 and 0.97 for breath and watery stool samples, respectively. The potential to detect CRC by scent offers the promise of treating this relatively common cancer earlier, and hopefully with a better outcome.

Type 1 diabetes, or juvenile diabetes, has long mystified scientists. Although research during the last few decades pinpointed its cause - the autoimmune attack of insulin-secreting beta cells in the pancreas - its prevention has remained a mystery. The use of nano-engineered vaccines, however, may finally offer clues to preventing this disease that affects nearly 1 million people in the United States.

Much like a science fiction movie, scientists at the Marche Polytechnic University in Ancona, Italy, have uncovered multi-cellular organisms that do not rely on mitochondria and oxygen to live and reproduce, unlike multi-cellular organisms predominantly found on Earth. These three species, of the phylum Loricifera, look like jellyfish, are about one millimeter in size and live 2.2 miles below the deep Mediterranean Sea floor in a basin near the western coast of Crete.
