Perovskite solar cells can not only emit light, they can also emit up to 70% of absorbed sunlight as lasers. Critical signaling molecules can be used to convert stem cells to neural progenitor cells, increasing the yield of healthy motor neurons and decreasing the time required to grow them. Mexican blind cavefish are so close…

The evolutionary capacitor

Heat shock protein 90 (HSP90) helps keep proteins in the body folded properly and is thought to compensate for variations that occur in proteins over time. In a study published in Science magazine, Dr. Nicolas Rohner and colleagues showed that stress can affect the ability for HSP90 to do its job thereby unmasking these alternative…

Ten new species of snails in the genus Plectostoma have been discovered in the limestone hills of Southeast Asia. Limestone hills are not common in this region, so the individual snail species are often isolated to just one hill. Therefore mining has threatened their existence and several species are already extinct or endangered. Source: LiveScience

Scientists use a ‘gene gun’ to insert a gene from a flowering plant called rockcress into the cells of wheat seeds. The genetically modified wheat became more resistant to a fungus called take-all, which in real life can cause “a 40-60% reduction in wheat yields.” T-cells from six HIV+ patients were removed from their bodies,…

Frog songs attract bats

Check out this neat video highlighting how frog-eating bats are using frog mating calls to know where to pick up dinner:

Friday Cephalopod: Frolicking in blue

I just read a really neat study from researchers at Texas A&M University. While admittedly this is not comparative physiology, it was just too interesting not to share. In a study published in the Journal of Nutritional Biochemistry, Dr. Luis Cisneros-Zevallos and colleagues found that administering peach extract to mice inhibited the metastasis (i.e. spread)…

Salamanders can be a proxyindicator for climate change. Changes in salamanders have been linked to climate changes during ancient times, and in a very recent study, salamanders in the US Appalachians seem to have changed in relation to anthropogenic global warming. In fact, the changes observed in these Appalachian salamanders is quite large, very rapid,…
