12:04 PM | Positive Reinforcement is Defined by the Receiver, Take Two
I’ve been thinking a lot lately about how important it is to remember that “reinforcement” and “punishment” are defined by the receiver. I’m not sure what got me thinking about it. Perhaps it was learning about a study that found cows perceived being yelled at as distressing as being shocked with an electric prod. Or […]

12:11 AM | How Oxytocin Changes Mothers’ Brains
We all know that Nature likes to publish sexy stories. Well, at least we scientists know. For the rest of you, Nature is one of the premier scientific journals that everyone and their mom tries to get their papers published in. The competition is brutal. Not only do you need to have a flawless story (as I’ve discussed before), it usually needs to be sexy, too. … Continue reading →

Picture this, if you will: you and your compatriots have been deathly silent for hours, stalking through dense vegetation. Your prey is none the wiser of your presence and it must remain that way if your family is to survive another day. And there it is! - through the leaves, vines and trees you see […]

11:20 PM | Introducing Lassa-VSV, a hybrid virus that kills brain tumours
Last month, I wrote about using Salmonella to deliver anti-cancer compounds to tumours. Today, I’m sharing with you a paper on cancer-fighting viruses. Why the recent focus on microbiology and cancer? Because they’re much more interconnected than you would think and because they’re both so cool! (And maybe also because I’m a microbiologist and my […]

11:20 PM | How should one handle a racist on twitter?
I got pulled into an upsetting thread on the genetics of race with the Digital Darth Vader Chuck Jones. And I am deeply conflicted. Ignoring these Chucks is bad. But engaging with them increases their visibility and grows their twitter following. It's a lose-lose situation for us and a win-win for Chucks. Any advice? @aepton @joshtpm @lteytelman please read Nicholas Wade's book. — Charles C. Johnson (@ChuckCJohnson) April 17, 2015  I pointed Chuck to Mike Eisen's On Nicholas […]

3:26 PM | e-Cig usage needs our attention
pharmtastic: An interesting study published earlier this month in PLOS ONE, whose major goal was to develop a murine [mouse] model to study the effects of e-cigarette smoke, found that repeated exposure to e-cig smoke resulted in inhibition of pro-inflammatory processes (leading to decreased concentration of pro-inflammatory cytokines) thereby making them more susceptible to bacterial and viral infections. The authors attribute these effects to the high levels of free radicals (although […]

2:50 PM | Where agricultural technology doesn't work - rice terraces
This is a very handsome image of human transformed land. TPP's initial impression was that this was a marvelously fluid work of stained glass art. This image shows rice terraces in Yunnan China that literally show the topography of a valley most people would think is too steep for agriculture. This tells you how valuable land is in some places that people would go to so much trouble for agricultural use. Clearly any modern agricultural equipment bigger than a rototiller is simply useless. It's […]

There’s a nice, but dense, paper out today (pdf here) from Singaporean biophysicists and chemical engineers at MIT demonstrating how existing theory fails to model the tying and untying of knots in polymers. Such knots are found in nature’s macromolecules: proteins and DNA. The most probable knot size (the ’metastable’ size) was found to vary non-monotonically (‘not strictly increasing’) with channel size, as per existing (Grosberg-Rabin) theory. In the […]

10:57 AM | Chemistry Central and the ORCID identifier
If you are a scientist you have heard about the ORCID identifier by now. If not, you have been focusing on groundbreaking research and isolated yourself from the rest of the world, just to make it perfect and get that Nobel prize next year. If you have been working on impactful research, Nobel prize-worthy, and have been blogging and tweeting about your progress, as a good Open Scholar, you know ORCID is the DOI for "research contributors" and you already have one yourself, and probably also […]

Screenshot of an old CDK-basedJChemPaint, from the first CDK paper.CC-BY :)Already a while ago, the American Chemical Society (ACS) decided to allow the Creative Commons Attribution license (version 4.0) to be used on their papers, via their Author Choice program. ACS members pay $1500, which is low for a traditional publisher. While I even rather seem them move to a gold Open Access journal, it is a very welcome option! For the ACS business model it means a guaranteed sell of […]

7:00 AM | How The Wright Brothers Set Back Aviation History
The Wright brothers are generally credited as being aviation pioneers, but it's up for debate just how much they held back the field. After confirming their craft could fly and could be controlled, they sat on the design for some time while they tried to get someone to buy it sight unseen. When that didn't work---and when they were being surpassed in technology and advances---they settled for trying to slap everyone with lawsuits. Their idea man spent much of his time in court, and it's […]

The magnificent creature circled Hercules several times and gave the cameras a chance to capture it in all its glory. According to the scientists, encounters between sperm whales and ROVs are
