*Hungry plant, tiny genome*

The plant Utricularia gibba is, perhaps unfortunately, more commonly known as the humped or floating bladderwort. While that sounds like a name that would get a plant beat-up on the playground, U. gibba is decidedly bad-ass in a few ways. Firstly, it's a carnivore. Carnivorous plants are cool. It eats water insects with the tiny bladders pictured below, and it's quite efficient at it apparently. Secondly, it's classified as a weed in most of the world. "Weed" is actually just shorthand for "well adapted to its environmental niche". That's what we're all striving for and U. gibba seems to be doing a good job of it so far.

Now it has one more quality to add to its coolness: a svelte genome. U. gibba has a respectable 28,500 genes but they're all squished into a genome that is just 82 megabases... more »

Beard-second

The beard-second is a unit of length inspired by the light-year, but used for extremely short distances such as those in nuclear physics. The beard-second is defined as the length an average beard grows in one second. Kemp Bennet Kolb defines the distance as exactly 100 angstroms, (i.e. 10 nanometers), as does Nordling and Österman's Physics Handbook. However, Google Calculator supports the beard-second for unit conversions using the value 5 nm, i.e. half the value according to Kolb and Physics Handbook.

"Ferreting out the Truth": Panel Discussion on H5N1 Influenza Virus || Event Page: http://goo.gl/MjFCB 

Later today, +Buddhini Samarasinghe and I are hosting the +ScienceSunday Hangout On Air. This week's topic is on the research being done on the H5N1 Influenza Virus. We'll be discussing not only the research that's been done, but also why there's been so much controversy about it in the news and social media. Is there something we should be concerned about?


Our discussion panel consists of:

+Josh Witten is, of course, entirely correct. There is no greater proof that humans are free from natural selection than the cry of a baby. Or a toddler. Or a big boy who should know better and should really start acting his age. Because "Oh my god there is a [large hungry predator] out there who is going to eat us if you don't be quiet" doesn't work.

And yes, I have tried.

Sometimes you have to spend money to make money

Keeping people addicted to a dangerous product is a lot of hard work.  Everyone seems to be against you and they always are trying to think up new ways to make it harder for you to get people addicted.  You have to constantly come up with clever new business tactics, like, I don't know, say a tumour that has to keep growing and changing.

Take tobacco for example.  Undoubtably dangerous, yet still sold everywhere.  Governments and health professionals and scientists and other do-gooders are constantly trying to discourage people from smoking.  One of the tactics is to impose tobacco taxes.  So, how does the industry counter this and keep the nicotine flowing?  They lower their prices on the cheap cigarettes to match the tax increases.  Get everyone addicted on the cheap stuff and then move them up to the primo productwith th... more »

49th Parallel Coffee - Local Vancouver roaster

Coffee is an important part of every day, but it's particularly important on Mondays.  Like most of Canada, Vancouver coffee is dominated by Tim Horton's and Starbucks.  But there are a myriad of small coffee shops and even a few local roasters.  One of these is 49th Parallel.  They have a couple of cafes where you can get an espresso and a swanky donut, but they also sell their roasted beans to various BC restaurants and to the public at a few grocery stores.  A big plus with their beans is that the roasted date is stamped right on the bottom of the bag, and it's usually only  a week or two old. (JJ Bean does this too.)  Most other brands have no date or a "best-before" date that is a year in the future.  Ick.

Vancouver Housing Price Drop

It seems clear that Vancouver's housing market is now swirling the bowl, with some areas down 10% from the peak a year ago. This is an interesting graph comparing the drop from peak prices (April 2012) to some of the big cities in the US.  [Graph source and more discussion here: https://vancouverpricedrop.wordpress.com/2013/04/19/drop-from-peak-chart-march-2013/]

Vancouver is the light green line that's just about 10 months along, and it appears to be tracking Seattle pretty well.  It will be interesting to see how long the spring bump lasts.  I'd guess not long but we'll have to wait and see.

I'm posting this in the BC forum but everyone else in Canada might find it interesting, if only for the schadenfreude of seeing Vancouver's real estate arrogance dry up just a bit.

Points of View returns to Nature Methods

Gene patents save lives.  Or something like that...

Without the patents, our work would not have been possible. We would not have been able to raise the funds necessary to decode the genes, design and deliver the tests, interpret the results, and help patients.

Exactly.  Which is precisely why testing for the cystic fibrosis gene CFTR is only available in, let's see...

Great profile of the hilarious and clever +Tabatha Southey

Southey is a study in opposites: a shopper at Holt Renfrew who bikes there, a high school dropout with a national column, humourous while making a serious point, a regular joe outside the journalism world, and a celebrity inside it. On Twitter, she banters with other journalists (frequently outwitting them), and come Saturday morning, big names retweet her column—their equivalent of a thumbs-up. Yet, she still has the same voice and outlook she did 10 years ago, and writes about omnibus bills the same way she wrote about getting drunk with men.

The recent issues around the #HeLa genome publication generated a lot of interest in genomic data, privacy, sharing, and access to the sequence data of individuals. The research rubber is hitting the road now, and will only continue to speed up.

Do you want to hear bad news about your own genetics?  You might not get to choose

When the authors of a report include "Highly Anticipated" in the title you know that either: 1) it is highly anticipated, or 2) they're trying to get some attention.  In the case of the recent ACMG guidelines ACMG Recommendations for Reporting of Incidental Findings in Clinical Exome and Genome Sequencing Report (www.acmg.net) it's both.  And what do these recommendations say?  For one thing, they say that if you get a sequencing test you can't choose to not hear about anything bad that is discovered.

As most people are aware, recent advances in genome sequencing technologies have made it possible to sequence most or all of a patient's genome for clinical diagnostic and predictive testing.  Here's a couple of open-access reviews to get you up to speed on thedeta... more »

Molecular Scissors: Restriction Enzymes

✄ Microbial Underworld: Imagine a cut throat, competitive underworld where intruders are efficiently decimated by a custom-made weapon that slashes right through their life lines. These ancient molecular scissors evolved in bacteria to defend against parasitic viruses, called 'phages. Better known as restriction endonucleases, these enzymes recognize a specific DNA sequence as their target. A short 6-8 letter sequence effectively marks the hapless victim for destruction. How does the host go unscathed? The same sequence is protected by a chemical modification (methylation) that makes it invisible to a veritable incarnation of Edward Scissorhands.

✄ Snip, Snip! The molecular scissors are named after the bacteria of origin. For example, Eco RI signifies that it was from the E. coli bacterium. Several thousand have beendis... more »

Interfering with RNA

A birthday tribute to someone I really admire here on G+, who is an amazing mentor and friend. Happy Birthday +Rajini Rao, hope you have a wonderful year ahead and it's been a pleasure knowing and working with you on our many projects together on G+!

A few days ago during our ENCODE Hangout on Air (http://goo.gl/H6KDE), I mentioned microRNAs. I wanted to write a post today about the general mechanism of how a gene can be 'silenced' through a process known as RNA interference.

• As we explained during the Hangout, the Central Dogma of Molecular Biology is DNA --> RNA --> Protein. This means the DNA blueprint makes a sequence-specific copy of RNA, which in turn acts as a blueprint for a specific sequence of amino acids which make up a protein. 

• So imagine if you could somehow destroy the RNAblue... more »
