This FREAKS me out

Today’s Recipe:

Combine equal parts

…and you’ll get this great article from Scientific American about a major new discovery: fish living under 740 meters of ice in Antarctica. Researchers drilled through the Ross Ice Shelf into a 10 meter deep wedge of water sealed above by that massive amount of ice and below by Antarctica. The water was so clear, the habitat so seemingly inhospitable, the evidence for life so lacking, the thought of anything more than a few microbes living there seemed impossible. And yet –

At last Burnett and Zook brought Deep-SCINI to a standstill a meter above the bottom, while they adjusted their controls. People in the cargo container stared at an image of the sea floor panned out on one of the video monitors, captured by the forward-looking camera. Then someone started to yell and point. All eyes swung to the screen with the down-looking camera.

A graceful, undulating shadow glided across its view, tapered front to back like an exclamation point—the shadow cast by a bulb-eyed fish. Then people saw the creature casting that shadow: bluish-brownish-pinkish, as long as a butter knife, its internal organs showing through its translucent body.

Apparently they saw 20-30 fish, some “shrimpy” things and a handful of other invertebrates. Can you IMAGINE how exciting that was?! Oof. Very cool. Check out the whole story for more details!

Academia vs. Industry

All of the contributors here at NiB are at a not permanent point in their career. Some are finishing their PhD, some wrapping up post docs, but all of us are on some level thinking about the next step.

And as such, I am considering the perpetual question, should I stay in academia or leave and go to industry?

The biggest problem is that I don’t know what industry looks like, and most of the information I hear about the differences are rumors. So this article, where a STEM PhD compares his own experiences in industry vs. academia, is really enlightening.



First new antibiotic in HOW long?

Part of the hoopla over antibiotic resistance involves the lack of new drug targets. But this week, Ling et al. published a paper titled “A new antibiotic kills pathogens without detectable resistance” – talk about a big splash! Not only is it the first new class of antibiotic since 1987 (!) but they also discovered it using non-culture based methods and failed to detect any mutants when they screened a couple of bacterial species for resistance. Although it has yet to be tested on humans, trials in mice were positive. The primary article is behind a paywall (I’ve pasted the abstract below) but there’s some good media coverage where you can read more here and here. Way to go, scientists!

ABSTRACT: Antibiotic resistance is spreading faster than the introduction of new compounds into clinical practice, causing a public health crisis. Most antibiotics were produced by screening soil microorganisms, but this limited resource of cultivable bacteria was overmined by the 1960s. Synthetic approaches to produce antibiotics have been unable to replace this platform. Uncultured bacteria make up approximately 99% of all species in external environments, and are an untapped source of new antibiotics. We developed several methods to grow uncultured organisms by cultivation in situ or by using specific growth factors. Here we report a new antibiotic that we term teixobactin, discovered in a screen of uncultured bacteria. Teixobactin inhibits cell wall synthesis by binding to a highly conserved motif of lipid II (precursor of peptidoglycan) and lipid III (precursor of cell wall teichoic acid). We did not obtain any mutants of Staphylococcus aureus or Mycobacterium tuberculosis resistant to teixobactin. The properties of this compound suggest a path towards developing antibiotics that are likely to avoid development of resistance.

Everything you ever wanted to know about Vaccines, in one cartoon!

As a scientist I often get questions about new and exciting science in the news! Sadly most of this isn’t new… and the excitement is false.

But answering the questions, and better informing the public is worth it.

The anti-vaccine movement really bothers me, and people saying “vaccines cause autism, you can’t prove it doesn’t!”… sigh.

Luckily I stumbled across this amazing cartoon that answers every question you could ever have about vaccines.1-0YNh0FaiIcPmXzgzRO5u2g


Women in STEM 2014

The New Year is always a great time for reflection – Science, I Choose You! has put together an extremely link-tastic review of how 2014 went in terms of women in science. It reminds us of both the good (a woman won a Fields Medal in mathematics for the first time ever!) and the bad (specifically #gamergate and #shirtstorm). I highly recommend checking out the whole post – here!
