Xenopus 1 Social Network

2009-11-11T11:26:00.000-08:00

at Xenopus 1, we have three goals in our social media presence.
Of course, we want to extend brand awarenes. But we also want to have fun in a community of dedicated people who we have a natural connection with: A love for and use of the xenopus frog. We don´t want to sell frogs or create binding relationships unique to that end (of selling a frog). We do want to inform and collaborate and learn. And of course be in the loop, so to speak.
We also want to engage and connect the fascinating and dedicated community of laboratories and research directions and institutions where xenopus are used. There is a chearleader section that has to be a part of the community given the need (and competitivity) in research, mainly concerned with talent, etc. so any glory the frog gets as connected to biomedical fields, genetics, cellular development etc. adds luster and romance. It makes the humble frog attractive. It makes the research with it glamorous. Could a mouse do that? So, for today I passsed the three goal limit, wanna buy a frog?

There's not much that could eclipse the USA science noble trove. Except maybe my much anticipated Tropicalis Lab Notes. However, this NYT article and the the ideas it reports on are game changing concepts and show the flip side of cognitive development.

Take One: Nobel Prize for Obama

2009-10-09T07:36:00.000-07:00

I sorta get the premature arguments...but, Nobel committees have to DO THINGS too. What he's put out there has been right, what he's acted on has been right, his language has been right and his intellect as sharp as his stage unequalled. There's been a ripple effect through consciousness-in many areas-a soothing of the edginess for many in the world. And the surprise of his election, given many think we're racists, simple, war-mongering, provincial, elitist, etc. really threw a curve at the perceptions of the USA. I mean what a guy for the moment! For example: In terms of the posturing by politicians worldwide referring to the evil empire-You can’t stir people up or win votes anymore asking to vote against the USA as opposed to for some good policy. The ripple effect, in this sense, has been multi-faceted and could go on and on and on.

In this sense, who cares about premature?

Adding this up gets you a Nobel as much deserved, accidental or even premature, as anyone’s in history.

Truth is, previous post took our (frog) breath away. But back at it here with this news.

Speaking of Interesting, Welcome Dr. Nathan Dascal

2009-08-26T19:51:00.000-07:00

We have the great pleasure of presenting our distinguished guest contributor Dr. Nathan Dascal, Tel Aviv University. He explains these fascinating photos in detail:

Fig. 1: Oocytes expressing a CFP-labeled G protein activated K+ channels, GIRK. The channel is composed of Cerulean Fluorescent Protein (YFP)-fused GIRK1 subunit, coexpressed with a wild-type GIRK2 subunit. The image was taken using the ×5 objective, focused on the midline (equator) of the oocytes.

Fig. 2: Oocytes expressing a Yellow Fluorescent Protein (YFP)-fused G protein α subunit, Gαi3. The image was taken using the ×5 objective, focused on the midline (equator) of the oocytes.

Fig. 3. Zoom on one of the oocytes shown in Fig. 2, using the ×20 objective and an optical zoom of ×2. The focus was approximately at the equator of the oocyte, the thus the optical slice is a transverse plane through about the middle of the oocyte. Only the plasma membrane and a thin submembrane region are labeled with the expressed protein (which normally accumulates in the plasma membrane anyway), the rest of the oocyte being non-transparent.

Fig. 4. Zoom on one of the oocytes shown in Fig. 2, using the ×20 objective and an optical zoom of ×2. In this case, the focus was on the bottom surface of the oocytes, so that the optical slice shows a transverse plane through this part of the cell, as if viewing the oocyte's membrane and the adjacent submembrane region (about 5 μm thick) from below or above. The optically dense circles are the pigment granules, each about 1 μm in diameter.

Methods: Oocytes were devitellinized and injected with the RNAs encoding the different proteins 3-5 before the imaging experiment. All images were taken with the Zeiss 510 Meta confocal microscope, working in its spectral mode. Standard virtual coloring was used in all images. The spectra were collected with 405 nm (CFP excitation; emission was collected between 450 and 610 nm) and 514 nm (YFP excitation; emission was collected between 524 and 610 nm) laser lines.

And we raise frogs. Interesting enough. I guess we sorta like interesting things. This article points to the difficulty in changing behavioral patterns. It also gets to why some are "addicted to stress". A whole host of deep water questions can be raised here, as the frog blog gets its legs.

Monday postings. This was culled from bookmarked stuff. And it requires some thought (which is why it was bookmarked in the first place). So now it is out on the Frog Blog. And I'm still thinking about it.

The work of Darcy B. Kelley, Ph.D. with singing frogs outlined here. In reading this article about Nora Ephron's "Julia & Julia" I couldn't stop thinking of food and harmony in male/female relationships. And what about this in Discovery, showing that stressed birds sing better? More on Dr. Kelley's work here.

It is common knowledge that frogs paved the way for this. OK, a few chimps too. Apart for the hip hip hooray for the contributions to science frogs have made let's refer to what seems to be a dramatic Op-Ed piece in the New York Times.

Researcher in focus: Dr. Joseph Pomerening

2009-06-22T20:44:00.000-07:00

Dr. Joseph Pomerening, cell biologist at Indiana University has been named a 2009 Pew Scholar. Article here. The Indiana University news brief cites Dr. Pomerening's work as focusing on "how specific enzyme systems that control cell growth and division are regulated. Pomerening's research takes advantage of single-cell approaches along with cell sorting and live cell imaging of mammalian cells, as well as biochemical studies using Xenopus laevis egg extracts and embryos. He is specifically investigating the role of cyclin-dependent kinases, proteins that modify other proteins to alter their expression and that allow for dynamic changes that ultimately direct the cell to complete the complex and elegant process of division". Pictured from left to right are members of his lab: Joseph Ipe, Dr. Yan Ma (postdoc), Dr. Joe Pomerening (PI), Xi Yuan, Qing Kang. We thank Dr. Pomerening for the picture and salute him and his great team!

This ARS Tecnica article doesn't mean we will write the history for the common good around the The Greatest Frog on Earth™but one has to like administration's efforts to strongly re-position the US education system. The ARS Technica article quotes Obama: "I'm going to participate in a public awareness and outreach campaign to encourage students to consider careers in science and mathematics and engineering," Obama said, "because our future depends on it." If that actually pans out, it could be a powerful message, especially for fields that have had trouble attracting talented minority students."

When will we become a real frogblog? Meanwhile, this snippet Paul Cohen editorial item in the New York Times may be the definitive counter-balance to our nation's present course:

"Churn is the American way. Companies are born, rise, fall and die. Others come along to replace them. The country’s remarkable capacity for innovation, for reinvention, is tied to its acceptance of failure. Or always has been. Without failure, the culture of risk fades. Without risk, creativity withers. Save the zombies and you sabotage the vital.

If America loses sight of these truths, it will cease to be itself."

Big Ideas

2009-02-10T09:13:00.000-08:00

The topic of the day comes in the afterglow of Obama's first press conference, or speech. Timely enough given his attempt last night to de-mystify some very complex economic concepts. The sense is that we're in some very uncharted territory that many are trying to get their arms around. So here we are with the big ideas post. First one here. Second one here. let's close with a frog pic to keep it real.

Research

2009-02-04T06:47:00.000-08:00

This appears to be a game changer. Will the true triumph of Obama be the opening of the American Mind? (Allan Bloom's 1987 book outlines its closing). There was debate years back on Harvard's endowment-at that time 20 billion-and the shear weight of it being able to have great influence for the better. In fact, the discussion was on the moral responsibility Harvard may have in the endowment's final use. Time to connect trends:
Green, do good in the world. Obama's triumph as one of the intellect. Bad karma on going into wall street jobs. This means....
SCIENCE gets the brains and a new moral high ground!

Skin Cancer Drugs

Welcome. We'll not pretend to be the definitive FROGBLOG, but would like to have a fun forum. I invite all comments-this will keep things interesting. If things get wacky or go off topic, please don't be alarmed. Your faithful editor has been involved, in varied degrees, with xenopus frogs for almost 30 years and witnessed most of "what can happen will happen" highlights of frog husbandry. Quite to the point: My father, Robert D. Weymouth started Xenopus 1 in 1977 or so. So, let the posts begin!
