Bat disease: Scientists identify tissue-degrading enzyme in white-nose syndrome
Scientists have figured out the likely way that white-nose syndrome breaks down tissue in bats, opening the door to potential treatments for a disease that has killed more than six million bats since 2006 and poses a threat to the agricultural industry.

Ocean currents disturb methane-eating bacteria
Bacteria that feed on methane can control its concentration once it is released from the ocean floor. This can potentially stop the greenhouse gas from entering the atmosphere. But ocean currents can easily disturb dinner, according to a new study.

Sixth DNA base discovered?
Is there a sixth DNA base? A team of researchers suggests that the methyl-adenine that would regulate the expression of certain genes in eukaryotic cells could have a specific role in stem cells and in early stages of development.

Coal-tar-sealant runoff causes toxicity and DNA damage
Runoff from pavement with coal-tar-based sealant is toxic to aquatic life, damages DNA, and impairs DNA repair, according to new research. Rainwater runoff collected as long as three months after coal-tar-sealcoat application caused 100% mortality to minnows and water fleas, which are part of the base of the food chain.

Mechanisms for continually producing sperm
Continually producing sperm over a long time is important to procreate the next generation. Researchers have revealed that there are differences in reactivity to retinoic acid in spermatogonial stem cells, and these differences are a key factor to the persistence of sperm production with inexhaustible stem cells.

See flower cells in 3-D: No electron microscopy required
High-resolution imaging of plant cells is important in many plant studies, and the most commonly used method is scanning electron microscopy (SEM). But SEM can have limitations, including damage to material during sample preparation and high equipment costs. Researchers have developed an optical sectioning-3-D reconstruction method using a compound fluorescence light microscope. The new method is simpler and more cost-effective than SEM.
