Kids, don't try this at home: it's almost certainly not a good idea. But for those of you who are interested in physics, note several important points:

(1) The rocket fires under water: that works because it's a true rocket, carrying both fuel and oxidizer on board and not using air at all. The shape of the nozzle is also important, since water has an amazing ability to absorb heat and thus quench combustion; a caul around the nozzle keeps the water from getting at the ignition point from the sides.

(2) The primary explosion creates a roughly circular set of cracks. Those lead to "big" cracks opening up in the ice, as existing seams and weaknesses get expanded. 

(3) Note that the circular cracks become hexagonal (matching the big cracks) as you move outwards. What's happening is that the inner cracks happen first, and then those start the big cracks, which actually spread faster than the round ones, basically moving at the speed of sound in ice. By the time the last round cracks are forming, they're forming in ice that already has hexagonal cracks in it.

(4) Water is an incompressible fluid, which means that the shock waves are going to hit things under water very, very hard. This is likely to be lethal to anything underwater and nearby, and is how dynamite fishing works. The reasons why that's a terrible idea (and is therefore illegal nearly everywhere) are hopefully obvious.

(5) That said, watching things explode underwater is pretty cool.

1. Engineered Yeast for Opiate Production
After a number of years of effort by multiple groups the final enzymatic synthetic step in the pathway for opiate production (morphine, etc) has been completed and it is now possible to create strains of yeast that produce opiate drugs as part of normal metabolism With such a strain and basic fermentation skills morphine-producing yeast could be grown in a home-brew beer kit, but the original development was intended for cheaper, simpler, production of opiates. I disagree strongly with the alarmist commentary and propaganda around this, including this quote from the linked article “All told, decentralized and localized production would almost certainly reduce the cost and increase the availability of illegal opiates — substantially worsening a worldwide problem.” which I consider myopic; I believe this would substantially improve a worldwide problem. 

2. CRISPR-Based GMO Kill-Switch
CRISPR has now been employed in a novel way to trigger the removal and destruction of modified genes from genetically modified organisms and leaving the original genes intact It seems the system can kill the cells directly, inactivate or delete just the modified or introduced genes, or do both. Triggers for activating the system could include light levels, the presence or absence of a particular molecule - useful for controlling crops for example - and others. This seems to be similar in application to Terminator gene technology that was developed to limit the spread of GMO crops by preventing the growth of new seed, but in this case you would still get seed that could only be grow in desired areas. 

3. Optical Computing Developments
We had a trio of advances in optical computing this week. First, the smallest-ever silicon photonic beam-splitter has been demonstrated, designed by novel algorithms, measuring just 2.4 microns on a side, and promising faster on-chip communication and processing IBM announces new CMOS integrated silicon nanophotonics technology and new chips designed to work alongside electrical chips while transferring data at 100 Gbps (full HD movie in 2 seconds), first application in high end servers and data centers Layers of 2D graphene and boron nitride allow controlled propagation of confined light pulses (within the layered sheets) when a voltage is applied to the graphene

4. Continuous Roll Production of Graphene
A new continuous roll-to-roll production method for manufacturing large sheets of graphene and possibly other 2D materials At a rate of 2.5cm per minute the sheets are uniform and high-quality single-layer graphene; faster rates, up to 20x, still produce coated sheets but these are lower-quality with defects. While the process doesn’t yet produce sheets equal to the best batch-processing methods, different applications will have different quality requirements. Further improvements should result in improved quality and production speed. In related news a new 60% - 70% graphene ink formulation allows 3D printing of robust structures that retain many of graphene’s useful properties and used these as custom tissue scaffolds seeded with stem cells

5. Towards a Periodic Table of Cells
New microfluidics technology can efficiently isolate single cells from a sample for analysis and when combined with new technology for single cell genomic analysis via cataloguing the mRNA expression profile of single cells is leading to an explosion in data and new knowledeg about different cell types in different tissues This has resulted in identifying cells never seen before and recent studies such as a survey of 466 individual brain cells as a step towards a full cellular brain atlas, and mapping thousands of cells from a mouse brain to identify 47 different types. This is inching towards a periodic table of cells and a complete cellular map for the human body and their functions. In related news microfluidic techniques can now squeeze (immune) cells and force the introduction of desired antigens into them in order to create better and more effective vaccines out of the patient’s own cells

6. Better Implants that Evade the Immune System
New studies indicate that the geometry of implanted devices significantly affects how the body and immune system will tolerate their presence While the material is important their results suggest that larger, spherical devices are better able to maintain their function and avoid the buildup of scar tissue. 0.5mm spheres loaded with pancreatic islet cells to treat diabetic mice failed within a month, whereas 1.5mm spheres continued to function past six months. Similar performance improvement were observed in many materials and also in primates. This is a very interesting platform for introducing novel living biosensors and living drug factories into people. 

7. Wearable Muscle Sensors with MyoWare
A new muscle sensor designed to be temporarily stuck on to your skin above the muscle group that you want to use can be used to trigger commands in various electronic devices and is currently available via kickstarter This is related to the Myo gesture control armband that I’ve been keen to try out and I’d be tempted to back the kickstarter myself if the device came with bluetooth and could interface with my phone. I’m looking forward to further miniaturisation that allows these sensors and their wireless transmitters to be implanted and to take higher resolution readings. 

8. Designing a New Molecular Pump
The first entirely artificial molecular pump has been designed in which molecules pump other molecules The pump works via simple chemical reactions, driving molecules step by step up higher energy states and away from a natural equilibrium. The basic architecture involves a ring-shaped molecule that moves along a molecular thread or chain, storing energy as it does so by moving multiple rings towards one end. An interesting research novelty for now the ultimate goal is to have these little molecular machines power nanoscale devices, muscles, and perhaps perform computational operations. 

9. Learning Robots & Machines with Complex Goals
New deep learning algorithms enable some robots to learn new tasks via trial and error without pre-programmed details about the environment A variety of tasks were successfully tested including putting a hanger on a rack, assembling a toy, screwing a cap on a bottle, and others, with learning times averaging 10 minutes to 3 hours depending on the level of complexity. In related news a reinforcement learning approach has demonstrated game-playing software that is capable of creating a hierarchy of goals while working towards a delayed reward

10. Non-Mechanical Laser Scanner
DARPA has demonstrated its SWEEPER technology for enabling drastically improved LIDAR applications Unlike conventional LIDAR devices SWEEPER does not require mechanical components and instead exploits silicon-based on-chip optical phased array technology that can sweep a laser beam back and forth 100,000 times per second. This is expected to enable LIDAR systems that are drastically miniaturised and extremely low-cost. Given LIDAR systems in autonomous vehicles are one of the most expensive components in an autonomous vehicle the benefits for a diverse array of applications are immense. A future version of Project Tango could even have one of these devices.

Genetic basis for Mosquito Bite propensity. 
Why do some people attract all the mosquitoes while others are lucky? 
The answer seems to be in the genes. Scientists comparing identical and fraternal twins have zeroed in a genetic basis for why some people are tastier for mosquitoes. They compared 18 pairs of identical twins and 19 pairs of fraternal twins to see if there was any preference by mosquitoes. While there was biased preference between fraternal twins, there was none for identical twins. #mosquitoes   #mosquitobite   #genetics

Missing link found between brain, immune system; major disease implications
In a stunning discovery that overturns decades of textbook teaching, researchers have determined that the #brain is directly connected to the #immunesystem by vessels previously thought not to exist. The discovery could have profound implications for diseases from #autism to #Alzheimer's to multiple sclerosis.

WTF, Evolution?!

I recently stumbled across what has become my favourite tumblr blog - WTF, Evolution?! 

I like it because:

1. I get to be amazed by an extraordinarily diverse and baffling array of different creatures that I never knew could exist, let alone existed. 

2. The conversational commentary between the blogger and the "entity" that is evolution is pretty humorous at times :) E.g. criticising evolution for seemingly stupid design choices. 

* The latest entry on the comb duck reminds me of the bizarre head ornaments sported by the duck-billed dinosaurs. 

* An example of entries includes trap-door ants, penis-fencing flatworms, anus-dwelling pearlfish, sea-spiders with digestive organs in their legs. 

BUT IF YOU ONLY DO ONE THING TODAY: Watch the giant red leech having a meal:
