11:00 AM | A Tale of Two Strategies
by S. Marvin Friedman | Bacteria are for the most part gregarious organisms, living predominantly in dense communities consisting of multiple strains. In fact, the majority of infectious bacteria occur as multi-layered structures called biofilms, many of which are composed of multiple types of bacteria. As one can imagine, neighbor relations in such complex populations can be…

Our fortnightly round-up up of news from the Wellcome Trust research community… Mind and body: link between immune system and mental health The immune system may have a role to play in mental illness, suggests research from the University of Cambridge, published in JAMA Psychiatry last week. With funding from the Trust, as well as the […]

10:06 AM | Barche, il rumore attira il biofouling
Potrebbe esserci una spiegazione biologica del perché i piccoli organismi incrostanti, dannazione di tutti i marinai, prosperino abbondanti sopratutto sugli scafi delle barche e delle navi. E questo motivo potrebbe avere a che fare con il rumore: secondo un gruppo di ricercatori neozelandesi e australiani, infatti, lo sviluppo di alcune di queste specie potrebbe essere influenzato proprio dalle vibrazioni dei generatori. La curiosa correlazione è stata testata, per ora, soltanto […]

9:22 AM | The Power of Yawning
No one looks pretty doing it yet somehow, when we see someone compulsively distort their face into a yawn, we feel inclined to do the same. We share this odd behaviour with a whole bunch of animals, who each do it … Continue reading →

9:00 AM | How do you envisage the new Science Centre Singapore to be?
Re-imagining Jurong – That’s the title of Minister Khaw Boon Wan’s blogpost explaining Jurong’s transformation since Singapore’s industrialisation days and the impending transformation described by PM Lee during the National Day Rally on 17 August. Of particular interest to us at Science Centre Singapore (SCS) would be the announcement about the new Science Centre being… Continue reading »

9:00 AM | Logical Reasoning in Helsinki
Ken and I are in Finland this week co-teaching the Logical Reasoning in Human Genetics course that Ken and Joe Terwilliger have taught a number of times in a number of places over the last 10 years.  People in the class, and/or I, may do some live tweeting at #lrhg14. We'll be away for another week or so after the course.  We will do some blogging this week or next if we find the time.  If not, we'll be back the first week of September. Helsinki: Wikipedia

7:56 AM | CRISPR gene therapy prevents muscular dystrophy
Scientists have used the popular new CRISPR-Cas9 gene editing system to prevent Duchenne muscular dystrophy (DMD) in mice. DMD is caused by mutations in the dystrophin gene. Dystrophin forms part of the scaffolding inside each cell that maintains cell shape. In muscle cells, dystrophin links the contractile apparatus in the cells, called myofilaments, with the […]

7:00 AM | The Origin Of Murphy’s Law And Why It’s Real
If anything can go wrong, it will. This pessimistic phrase has been around for a long time, but it was only called Murphy's law when US Air Force colonel John Stapp applied the label after a technician working on his experiments with G-forces showed up with some key components that were completely defective. Until Stapp applied the unlucky man's name to the rule, it was earlier known as Sod's Law. And researchers have found out that it's a real thing---so next time it feels like the world is […]

5:11 AM | The exceptions of biology
Credit: Stanford University I like stating in my lectures that biology is a science of exceptions.  This in no way invalidates the rules; rather, they give us a new appreciation for them.  I have to confess that I love these exceptions.  In a previous post I wrote about organisms that were at the same time …

2:03 AM | Fototerapia, un tratamiento que avanza contra el cáncer
Investigadores de la Facultad de Farmacia y Bioquímica (FFyB) de la Universidad de Buenos Aires (UBA) sintetizaron compuestos fotoactivables, derivados de las ftalocianinas, y estudiaron su efecto fototóxico en células tumorales con resultados alentadores. La búsqueda de tratamientos eficaces contra el cáncer y con menos efectos secundarios que afecten la calidad de vida de los pacientes es constante. En la actualidad, el cáncer constituye una de las […]

Ophelia has summarized a series of science questions Richard Dawkins asked on Twitter. Hey, I thought, I have answers to lots of these — he probably does, too — so I thought I’d address one of them. Maybe I can take a stab at some of the others another time. I like this one, anyway:…

11:40 PM | The Importance of having a healthy brain
Originally posted on Thoughts of a peculiar mind:What exactly is our brain? Well, is a very important organ of our body which controls our thoughts, functions, our movements and pretty much everything.  Without our brain we wouldn’t be anybody; it evens controls our feelings. When we love somebody, that feeling actually comes from our brain,…

We last left Superhero PhD and her labmates in a state of noncompliance with the system that is supposed to support them. Fortunately, their misdeeds did not attract the attention of accountants higher up in the matrix. Even the recently purchased equipment from e-bay works just fine. These small triumphs make the days in the […]

3:29 PM | The time the cops pulled their guns on me
This post is not about science.I'm writing this because the horrific news out of Ferguson, Missouri—the killing of an unarmed man and the subsequent assault on the populace and media—has been bringing back memories an experience I had with the police ten years ago in Chicago.I should be clear about why I'm choosing to share this. It's not because I think my own problems are particularly deserving of attention in comparison to the violence done to Michael Brown, Eric Garner, and […]

“But the chief cause of our natural unwillingness to admit that one species has given birth to other and distinct species, is that we are always slow in admitting any great change of which we do not see the intermediate steps.” - Charles Darwin. "On the Origin of Species…" Chap. XIV. Recapitulation and Conclusion. 1st ed., p. 481. From the beautiful chapter that summarises the whole work and finishes with the more famous "endless forms most beautiful" quote.

“The human understanding resembles not a dry light, but admits a tincture of the will and passions, which generate their own system accordingly; for man always believes more readily that which he prefers.
