Integrated circuit techniques can do just about anything - perhaps even help cure sepsis.

Margination is natural phenomenon where bacteria and leukocytes (white blood cells) move toward the sides of blood vessels. Now it's the inspiration for a novel method of treating sepsis, a systemic and often dangerous inflammatory response to microbial infection in the blood.

Anthropogenic climate change is so anthropomorphic.  While we think we have a mighty impact on the atmosphere, sauropod dinosaurs millions of years ago shouldn't be left out of the pollution hall of fame - they alone could have produced enough methane to warm the climate many millions of years ago, according to a numerical model.

Like CO2, methane is a greenhouse gas, but with 23X the warming impact of CO2. It's produced by dying plants and cow burps - and cows share one thing in common with hulking sauropods, distinctive for their enormous size and unusually long necks, that were widespread about 150 million years ago. As in cows, methane-producing microbes aided the sauropods' digestion by fermenting their plant food.

This week's graph comes from a recent publication by the CMS experiment, the one I am a proud member of together with about 3000 colleagues from all over the world.

I make the case for replacing business executives with robots.*† This is no smart-ass slur on the intellects of executives. A transformation of business soon will be upon us. In the transformed enterprises, robots will take on more and more business decisions. Humans will retain a smaller but still crucially important role.

The argument involves ‘real options’ and ‘agency theory.’ Explaining them is simple, though lengthy. So let’s get started, using an illustrative example:

An opportunity requires Rineu Corporation to invest $10,000 now, with an assured first-year cash flow of $6,000. The second-year cash flow is uncertain with a 50-50 chance of either a $15,000 gain or a $5,000 loss.

Badly controlled diabetes are known to affect the brain, causing memory and learning problems and even increased incidence of dementia. How this occurs is not clear but a study in mice with type 2 diabetes has discovered how diabetes affects the hippocampus, causing memory loss, and also how caffeine can prevent this. 

Curiously, the neurodegeneration that Rodrigo Cunha,  from the Centre for Neuroscience and Cell Biology of the University of Coimbra in Portugal, sees as result of  diabetes is the same that occurs at the first stages of several neurodegenerative diseases, including Alzheimer’s and Parkinson’s, suggesting that caffeine (or drugs with similar mechanisms) could help them too.

The medium in which light propagates is space. This space can curve. The curvature is not static. So, this space moves. Its behavior can be analyzed by a kind of fluid dynamics. Let us call this method quantum fluid dynamics. It differs from conventional fluid dynamics in the medium that is treated. In conventional fluid dynamics this is a gas or a fluid. Fluid dynamics concerns density distributions and currents. In quantum fluid dynamics these are space density distributions and space current density distributions. They can be combined in quaternionic distributions, where the real part is the space density distribution and the imaginary part is the space current density distribution.

Entropy. A subject that comes back again and again and again and again and again in this blog. And so does the question in my inbox: "what exactly is entropy?" On the internet you can find a plethora of answers to this question. The quality of the answers ranges from 'plain nonsense' to 'almost right'.

Among cancer deaths worldwide, lung cancer is the leader. 

It isn't just the tumor cells, the growth of blood vessels controls tumors development and blood vessel growth is controlled by several signalling molecules. Scientists have discovered a molecule, phosphodiesterase PDE4, that plays a key role in this process and they have succeeded in reducing tumor growth in their experiments by blocking it.

Stars live for a long time - millions of years - but near the end of their lives, some massive stars go through what astronomers call the yellow supergiant phase.

Because the timeframe is so short, cosmically, witnessing a yellow supergiant phase is rare - almost as rare as a Kardashian staying married when ratings slip.  Like with celebrity relationships, if you want to witness the big meltdown you have to stay vigilant in astronomy. And keep your camera running.

The iconic Coelacanth are fish well-known as ‘living fossils’. Coelacanths were thought to have died out with the dinosaurs and then a living one was caught off the coast of South Africa in 1938, sending waves of excitement throughout the scientific world.
