As kids we were taught that fish, reptile and amphibians are cold-blooded, and birds and mammals are warm-blooded.
Simple, easy classification.
Researchers have found the first fish that is fully warm-blooded. A silvery fish the size of a car tire, the opah has a worldwide distribution.

A recent NPR piece on the series Joe’s Big Idea interviewed Caltech astrophysicist Shrinivas Kulkarni.
During the interview Dr. Kulkarni made the following statement:
“Many scientists are I think, secretly, are what I call ‘boys with toys.”
Needless to say this has had some impact on the blogosphere and the Twitterverse has gone nuts.
Read all about it in an excellent piece by Kate Clancy a woman scientist who plays with toys of her own over at Slate.
Or look at all these photos of women scientist playing with their toys:
Elizabeth Goldschmidt with her blue laser for studying Rydberg atoms
Karen James flanked by sequencing machines, explaining Sanger sequencing to citizen scientists
Katie Mack helping to build a new dark matter detector
Tanya Harrison playing with the Mars rovers
Species: Malayan flying lemur (Galeopterus variegatus)
Habitat: Rainforests and plantations of South-East Asia
“Take one look at a flying lemur, or colugo, sitting in a tree and it brings to mind a scrawny kid forced to wear his big brother’s hand-me-downs. Flaps of skin hang around its ankles and get in the way as it clambers awkwardly around the forest.
Once the colugo leaps into the air, though, everything changes. Its baggy folds transform into enormous wings as the animal sails gracefully through the canopy.”

The global pharmaceutical industry is being called on to pay for a 2 billion dollar innovation fund to find… better antibiotics.
We have noted before on NiB that there are very few new antibiotics in development, and that worldwide antibiotic resistance is on the rise. But economically speaking, developing new antibiotics is not in any given pharmaceutical companies best interest.
Read all about “resistance breakers”, “blue-sky” research and innovation funding for antibiotics over at BBC.
The Hokkaido Salamander comes in two varieties: “attack morph” for when they are in habitats with large prey and “defense morph” for when they find themselves in a space with a predator.
And it turns out the variety of salamander is plastic, and the associated transcriptomic differences have been found.

In 1965 a chemist named Hail Gordon Moore famously predicted that the number of transistors per square inch on integrated circuits would double every two year.
Originally, he assumed it would only last a decade or so. But technology advances have kept pace with what has become known as Moore’s Law ever since.
However, we are approaching the physical limit of Moore’s Law. Read about potential new advances, or the end of increased computing power over at Nature.
