Beautiful creation "This glorious 1960 Morris Minor 1000 is the work of friend of TLCB and one of our Master MOCer builders, the incredible Nick Barrett. Nick’s work has featured here countless times over the last two years, and today’s creation takes Lego vehicles to a new level of realism.

Months in the making, Nick’s latest creation is based upon a real 1960 Morris Minor 1000 nicknamed ‘Bluebell’ that he used to own in the 1990s. Under the unusually textured – and incredibly accurate – full-stud bodywork lies some truly inspirational Lego engineering. Working steering, suspension (live axel four link at the rear), opening (and locking) doors, bonnet and boot-lid, a working handbrake, adjustable seats, four speed gearbox and even motorised operational windscreen wipers all feature in a triumph of clever packaging."

The Spring 2014 issue of BioCoder is out now, download your free copy http://oreil.ly/1kp6HpT Fungi; DIYBiomimicry; Hacking Lab Equip + more

We’re at the start of a revolution that will transform our lives as radically as the computer revolution of the 70s. The biological revolution will touch every aspect of our lives: food and health, certainly, but also art, recreation, law, business, and much more.

BioCoder is the newsletter of that revolution. It’s about biology as it moves from research labs into startup incubators, hacker spaces, and even homes. It’s about a very old programming language that we’re just beginning to understand, and that’s written in a code made up of organic chemicals. It’s the product of a sharing community of scientists that stretches from grade school to post docs and university faculty.

Wood soldier fly - Xylomya maculata is one of the few species of the family Xylomyidae. They develop in dead wood, this individual was reared from rotten wood of a tree hollow. Focus stack of 8 shots - for higher resolution go to Flickr! https://flic.kr/p/n59tWP

A Xylomya maculata egy xylofág légycsalád kevés számú fajának egyike. Lárváik holtfákban fejlődnek, ez az egyed egy faodú korhadó anyagából lett kinevelve. Nagyobb felbontás a Flickr-en, link fent!

Hot Maggots
"My maggots bring all the heat to the corpse, and they're like - we're hotter than y'all."
Here's a fascinating post by +Bug Gwen on how maggots bring the heat in a dead, rotting body and how they might even use it against their competitors.

Maggots can generate their own heat. Scientists tested the amount of heat that a mass of maggots makes in order to better understand forensic investigations. The results could help police identify precisely when a body died as well as allow us to calculate the amount of maggots needed to turn into a flaming ball of insect larvae.

Science in action. "The real test will happen when the Planck team releases their results on B-mode polarization. The Plank satellite has polarization data at multiple wavelengths. If these results confirm BICEP2, then we can be sure of an inflationary effect. If not, then we’ve got more work to do. And so it goes, loop de loop, back and forth.

This is how science is done. One team puts forward a result, other teams push back with other ideas, and eventually the best result survives."
 
Loop de Loop

Last month research project known as BICEP2 announced evidence of inflation within the cosmic microwave background (CMB). Now a new paper argues that a different effect known as a radio loop could produce similar results, which raises the question of whether inflation was detected after all.

The evidence for inflation focused on what is known as B-mode polarization of the CMB.  The B-mode polarization has two causes.  The first is due to gravitational lensing.  The cosmic microwave background we see today has travelled for more than 13 billion years before reaching us.  Along its journey some of it has passed close enough to galaxies and the like to be gravitationally lensed.  This gravitational lensing twists the polarization a bit, giving some of it a B-mode polarization. The second mechanism which is more subtle, and requires more data to analyze. It is due to gravitational waves produced during the inflationary period of the big bang.  What the BICEP2 found was evidence of more B-mode polarization than expected by gravitational lensing alone.  Since there are two ways in which B-mode polarization can occur, they needed to show that this “extra” was not just due to lensing.  Thus, they argued, it must be due to primordial gravitational waves.

This new paper looks at another possible source known as radio loops. A radio loop is caused by large magnetic fields that span interstellar space.  When ionized plasma interacts with these magnetic fields, the charged particles spiral along the magnetic field. The spiraling charges then emit radio waves through what is known as synchrotron radiation.  As a result, radio waves are emitted all along the magnetic field loop, hence a “radio loop.”

But the authors point out that these loops can also produce microwave radiation, emitted by charged dust particles within the plasma.  These microwave emissions are in the same wavelength range as the cosmic microwave background.  The emissions are polarized, and their orientation would be similar to the B-mode polarization detected by BICEP2.

Once this “foreground effect” of galactic radio loops is accounted for, there may still be a residual B-mode evidence of inflation.  At this point we can’t be sure because it wasn’t taken into account in the BICEP2 results. What this new paper really points out is a weakness in the BICEP2 results, specifically that it was done at a single wavelength range.

The real test will happen when the Planck team releases their results on B-mode polarization.  The Plank satellite has polarization data at multiple wavelengths.  If these results confirm BICEP2, then we can be sure of an inflationary effect.  If not, then we’ve got more work to do.  And so it goes, loop de loop, back and forth.

This is how science is done.  One team puts forward a result, other teams push back with other ideas, and eventually the best result survives.

How +European Space Agency, ESA worked to get Rosetta off the ground after its original mission got scrubbed "Rosetta was originally planned for launch in February 2003, to head toward a small comet called Wirtanen. At that time, Rosetta was meant to be launched into space on board an Ariane 5 rocket. Unfortunately, just two months before the launch, this rocket – a new variant – failed during the launch of two communications satellites and had to be destroyed some eight minutes after launch to minimise the risk on ground. It was clear that a detailed failure analysis was needed and that Rosetta’s original launch date could not be maintained.

The result was that Rosetta – the spacecraft on which Europe had spent almost a billion Euros – was ready to go with no ride into space, as its target comet steadily arced around the Sun, moving further and further out of reach. And there was no detailed ‘Plan B’ ready for this disaster.

At the end of 2002, ESA was faced with the challenge of quickly redesigning the mission to minimise the time that the spacecraft might have to wait in storage and take advantage of another launch opportunity."
Today’s blog post was contributed by Ruediger Jehn and his colleagues working on the Mission Analysis team at ESOC. These experts work behind the scenes on all of ESA’s interplanetary and observatory missions to map out – in the most incredible detail– every aspect of a mission before it’s launched.

What the H#@% is this, +Google Maps ? The location of Braddell MRT station is way off. Sure you still want to trust Google Maps and not OpenStreetMaps, which gets it right [ http://www.openstreetmap.org/#map=18/1.34070/103.84586 ], +Michael Tan ?
