Nature research paper: Rewiring an olfactory circuit by altering cell-surface combinatorial code

Rewiring an olfactory circuit by altering cell-surface combinatorial code - Nature
In Drosophila, changing the expression of a small set of cell-surface proteins in just one type of olfactory neuron rewires its connections almost entirely to a new postsynaptic partner neuron type, altering the fly’s odour response and courtship behaviour.

It's time to remove laptops from classrooms.

24 experiments: Students learn more and get better grades after taking notes by hand than typing. It's not just because they're less distracted—writing enables deeper processing and more images.

Neuroendocrine control of calcium mobilization in the fruit fly
www.nature.com/articles/s41...

We “re”-discovered the calcium storage site in “boneless” Drosophila and revealed how calcium mobilization is regulated.

In our newest paper published in @natcomms.nature.com, we show that DAF-16/FOXO and HLH-30/TFRB promote healthy aging, in part, by activating lipid metabolism genes that remodel lysosomes into tubular networks (more in comments below).

Bluetorial-Jim Watson

I met Jim Watson a few times but did not know him well. However, I was greatly influenced by his book “The Double Helix”. He was a complicated human being with some very, very bad features, but some good contributions.

What follows is my personal perspective.

If you believe either that Franklin discovered the double helix, and / or Watson and Crick stole her data, ask yourself how you know this. Then take a read of this article.

Mariana Wolfner has spent her life studying a creature so small it could rest on the tip of her finger. In her hands, the fruit fly Drosophila melanogaster becomes something extraordinary, a key to understanding how life is shaped, sustained, and passed on. On a windy fall afternoon at Cornell, she sat surrounded by papers, notes, and journals. The light came through the window in soft bands as she lifted a golden model of a fly and smiled.
