Researchers release new variety of asparagus

...breeding program in the state, the superior hybrid marks the third time that UCR has released a new variety of the vegetable, the most recent being 1982. "Particularly now, the asparagus industry in this country needs new varieties of the vegetable ?varieties that can compete with those produced in other...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...erent vertebrates (frogs, chickens and zebrafish), marks the first time that a single common mechanism has been identified in left-right patterning in three distinct species. Such a discovery may have far-reaching implications for the understanding of craniofacial development, right-left hand preference, ...

One fish, two fish: New MIT sensor improves fish counts

...were seeing fish - tens of millions of fish. This marks the first time scientists have been able to see the patterns formed by large fish populations. Makris found that fish often congregate in an hourglass pattern, also found among other animals, with a thin "bridge" connecting the two ends. The research...

Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...ay, TRB3 serves as a go-between for an enzyme that marks ACC for degradation," says Jose Heredia, a graduate student in Montminy's lab. TRB3 levels in adipose tissue usually rise only during fasting, when ACC should be turned off. Heredia and co-first author Ling Qi, Ph.D., reasoned that keeping the TRB3...
