This shot shows Saturnís rings nearly edge-on, but dominating the scene is Rhea, 1500 km (950 miles) in diameter, seen here 61,000 km (38,000 miles) distant. Below it is Dione, to the right and just above the rings is Epimetheus, and Tethys is all the way on the right, below the rings......Look to the right of Dione, right at the rings. See that tiny bump? Thatís dinky Prometheus, all of 119 km (71 miles) along its longest dimension ó itís basically a spud orbiting Saturn.

This website (http://scienceblogs.com/aetiology/)is the blog of an epidemiologist, the tracking and study of the progression of diseases and disorders through populations. It's an essential medical science and how flu vaccination predictions are made, for just one example.

However, the reasons for this Campylobacter food poisoning outbreak in two men in the US is just....well....not right! On so many levels.

This is how they caught it. Not for the squeamish (http://scienceblogs.com/aetiology/2011/12/castrating_sheep_with_teeth_no.php), hence only the link.

I caught Campylobacter from undercooked chicken in a restaurant a few years ago. Great weight loss programme but expensive on underwear. Never been the same since.

If you did biology at school you may have come across the Peppered Moth as an example of natural selection. In short, during Britain's industrial era lots of trees became darkened with soot and dead lichen killed by acid rain. This caused the local moth population to become largely black in colour around cities but the county population remained white with peppery black spots. After the clean air acts passed by government in the 1950's the city populations reverted back to its peppered form. The selection pressure was from bird predation. A nice simple and elegant story of natural selection in action in less than two centuries but troubled by flawed experiments causing some doubt.

A newly released paper has confirmed the theory of bird predation with new and better designed experiments. Head over here (http://whyevolutionistrue.wordpress.com/2012/02/10/the-peppered-moth-story-is-solid/) for an easy to read explanation of the Peppered Moth and the new data. It's an interesting slice of science history.

He was not much taller than me, but he was a giant of a man. He was as kind as he was intimidating.

I donít remember what I said to him, or what he said to me, because all I could think the entire time was ďThis man has walked on the ----ing moon.Ē

An interesting article on survivorship bias. (http://youarenotsosmart.com/2013/05/23/survivorship-bias/) Examples from WW2 and interesting ideas and experiments from psychologists and scientists.


After any process that leaves behind survivors, the non-survivors are often destroyed or muted or removed from your view. If failures becomes invisible, then naturally you will pay more attention to successes. Not only do you fail to recognize that what is missing might have held important information, you fail to recognize that there is missing information at all.

Not only do you fail to recognize that what is missing might have held important information, you fail to recognize that there is missing information at all.

This may be true but if you work for a company that employes a bunch of idiots who like to "play the game" then the only attention you get is when you screw up or make a mistake (Failures) and the 99% of good you have done (successes) is ignored.

EDIT: have not read the full article, will read it later, heading out.

MrMojay
28.06.2013, 19:31
Read some of that article in relation to what you posted retro and what they say about advertising and magic tricks is very true, they only show the success and not the failure, I think in science that all of the data should be releveant, all the failures and repeated attempts that lead to a single success should not be ignored, YAY we have a success!!....but look at how many failures and mistakes we made along the way, what does that tell us, did we succeed by chance or on purpose, if on purpose then why did so many failures happen?. It is also my understanding that a lot of humanities scientific discoveries were actually accidental, another thing to ponder. ;)

Survivorship is an interesting debate, I mean I can look at someone who is obese and coughs a lot and suffers with diabetes and aching joints and finds it hard to do anything, I will see all of that persons failures and know just how they got into that state and use that persons failures to improve my own life...hmmmm.

I like this quote in relation to lucky and unlucky as I do not really believe in luck.


The harder they looked, the less they saw. And so it is with luck – unlucky people miss chance opportunities because they are too focused on looking for something else. They go to parties intent on finding their perfect partner and so miss opportunities to make good friends. They look through newspapers determined to find certain type of job advertisements and as a result miss other types of jobs. Lucky people are more relaxed and open, and therefore see what is there rather than just what they are looking for.” – Richard Wiseman

A great quote from the article.


If you spend your life only learning from survivors, buying books about successful people and pouring over the history of companies that shook the planet, your knowledge of the world will be strongly biased and enormously incomplete. As best I can tell, here is the trick: When looking for advice, you should look for what not to do, for what is missing as Phil Plait suggested


those who fail rarely get paid for advice on how not to fail

Source: original paper, pdf. (http://www.tau.ac.il/~tromer/papers/acoustic-20131218.pdf)


Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.
Beyond acoustics, we demonstrate that a similar low-bandwidth attack can be performed by measuring the electric potential of a computer chassis. A suitably-equipped attacker need merely touch the target computer with his bare hand, or get the required leakage information from the ground wires at the remote end of VGA, USB or Ethernet cables.

Don't whether to be impressed or really worried!

MrMojay
19.12.2013, 16:35
Hmmm, have they actually got this to work, because RSA uses 2 really large prime numbers which get multiplied, now for someone to try and decrypt it they may get their hands on the result of the multiplication of the 2 prime numbers but they will have an impossible time trying to figure out what the 2 prime numbers that were used.

In any case I am not worried, by the time they work out how to crack RSA quantum computers will be in service and trying to hack a system that is all things at all times is going to be a nightmare for all the attackers out there. ;)

The Singularity Is Further Than It Appears ("http://www.antipope.org/charlie/blog-static/2014/02/the-singularity-is-further-tha.html#more)


Are we headed for a Singularity? Is it imminent?

I write relatively near-future science fiction that features neural implants, brain-to-brain communication, and uploaded brains. I also teach at a place called Singularity University. So people naturally assume that I believe in the notion of a Singularity and that one is on the horizon, perhaps in my lifetime.

I think it's more complex than that, however, and depends in part on one's definition of the word. The word Singularity has gone through something of a shift in definition over the last few years, weakening its meaning. But regardless of which definition you use, there are good reasons to think that it's not on the immediate horizon.

Read the comments too if you like worrying about this stuff :)

How did wolves change the behaviour of Yellowstone Parks rivers?

The re-introduction of wolves into the park has had a dramatic effect at every level of the local ecosystem (a positive top down trophic cascade). One of them was the predation of out of control deer populations that over-grazed the land, killing trees and shrubs that helped to prevent soil erosion. As a result the course or the parks rivers has stabilised and soil erosion has reduced not just at the rivers but on the hillsides too. This beautiful, short video explains the effects the wolves have had from the rivers to the birds in the sky.

And i won't even start on this one:Facebook intends to acquire virtual reality hardware company Oculus VR for $2 billion. (http://gigaom.com/2014/03/25/facebook-to-acquire-oculus-for-2-billion/)
Mark Zuckerberg's status update.

I'm excited to announce that we've agreed to acquire Oculus VR, the leader in virtual reality technology.

Our mission is to make the world more open and connected. For the past few years, this has mostly meant building mobile apps that help you share with the people you care about. We have a lot more to do on mobile, but at this point we feel we're in a position where we can start focusing on what platforms will come next to enable even more useful, entertaining and personal experiences.

This is where Oculus comes in. They build virtual reality technology, like the Oculus Rift headset. When you put it on, you enter a completely immersive computer-generated environment, like a game or a movie scene or a place far away. The incredible thing about the technology is that you feel like you're actually present in another place with other people. People who try it say it's different from anything they've ever experienced in their lives.

Oculus's mission is to enable you to experience the impossible. Their technology opens up the possibility of completely new kinds of experiences.

Immersive gaming will be the first, and Oculus already has big plans here that won't be changing and we hope to accelerate. The Rift is highly anticipated by the gaming community, and there's a lot of interest from developers in building for this platform. We're going to focus on helping Oculus build out their product and develop partnerships to support more games. Oculus will continue operating independently within Facebook to achieve this.

But this is just the start. After games, we're going to make Oculus a platform for many other experiences. Imagine enjoying a court side seat at a game, studying in a classroom of students and teachers all over the world or consulting with a doctor face-to-face -- just by putting on goggles in your home. (Google glass any one).

This is really a new communication platform. By feeling truly present, you can share unbounded spaces and experiences with the people in your life. Imagine sharing not just moments with your friends online, but entire experiences and adventures (Bye,Bye privacy).

These are just some of the potential uses. By working with developers and partners across the industry, together we can build many more. One day, we believe this kind of immersive, augmented reality will become a part of daily life for billions of people.

Virtual reality was once the dream of science fiction. But the internet was also once a dream, and so were computers and smartphones. The future is coming and we have a chance to build it together. I can't wait to start working with the whole team at Oculus to bring this future to the world, and to unlock new worlds for all of us.

I like the HUD in general. We could get rid of large dashboards that obstruct your view. I just wondered what is the usefulness of seeing angle of terrain when your car is already on it? Wouldn't it be more useful to see the terrain like 100 m before you run into it... All though looking out of the windshield might actually suffice in general... :D

If those things are pressure sensitive they could also be used as speed detectors (law enforcement) and also as a tool for accident investigation (insurance/law) by showing positioning of vehicles before an accident.....of course this would mean storing tons of data on a temp basis.

If people try hard enough they will come up with arguments that the fat cats cannot ignore and this thing will get the go-ahead :)

Would a bad frost affect the structure and make it unsafe when thinking about high speed freeways for example. Would the heating element be able to cope?

One of the great debates amongst biologists is speciation - how do you define a species? Genetically? Geographically? Behaviourally? A set of rules for one species may not work for another.

In Europe, 2 species of crow have been examined, the carrion and hooded crows. Carrion crows range from the far north of Scotland, across Ireland and onto mainland Europe from Portugal to Germany. Italy and the rest of Europe have the hooded crow. However, genetic analysis shows that German carrion crows are more closely related to hooded crows than Spanish carrion crows, due in large part to the last ice age separating the populations allowing the German carrions to spread east and interbreed with the hooded population. Spanish and and German carrion crows behave identically to each other and have distinct behavioural differences to the hooded crows. Aaaargh, my head hurts :)

Here's a nice review (http://whyevolutionistrue.wordpress.com/2014/07/24/a-tale-of-two-crows/) of a paper published just 2 weeks ago that explains what is going on. The paper helps to confirm the theory of population genetics (http://en.wikipedia.org/wiki/Population_genetics).


Although deKnijff’s piece tends to concentrate on the semantic problem—what do we call these birds?—I find the genetic results more interesting: that they maintain their distinctness due to only a very few genetic differences, and those differences are largely bound up in rearranged sections of one small chromosome.

So when my European readers (and I am, for another few days, a writer in Europe) see a hooded or carrion crow, be aware that you’re looking at a remarkable case of recent evolution, and a puzzle that has largely been solved by work published in just the last two weeks.

They are incredibly intelligent, and can plan ahead - they can solve puzzles of over a dozen separate steps to get a reward. It has been shown in primates species that the larger a social group an individual has to keep track of, the brain increases in volume. Corvids are very social birds and I wouldn't be surprised if a similar trend was found in them.

Yes, exactly, touches bunches of associated topics I am interested in.

(1) Categorization connects to the whole problem of how we humans perceive our world, how we structure our knowledge and how it correlates to structures in our nervous system (including the brain).
(2) Selection and adaption connects to the complex interaction of genetics (body), habitat (environment), behaviour and the mind.
(3) Language.

These topics overlap and are investigated by a multitude of sciences.
I am not specifically interested in crows though, nor in biological taxonomy. :icon_lol:

Cosmology awes me. I have no real understandig - just gives me a good feeling to read about it or watch videos/simulations of the cosmos evolving. :)


Btw I am in general more attracted to the phenomenal (=subjective), rather than the scientifical "objective" side of things. Something that is often uncared for in modern sciences, since it is not observable outside of oneself. Imo all meaning and value derives from phenomenology, or from being-in-the-world and relating to it in a certain way.
Hence mainstream modern science is one specific way of relating to the world, and it is rarely discussed what meaning and purpose this kind of relatedness fulfills (or should fulfill).
In this regard we live in a very dangerous period of mankind, since our knowledge and tools evolve very rapidly, but our genetics and basic human behavioural patterns and insticts limp behind. As you know scientific knowledge is unfortunately too often misused as a tool to satisfy certain lower needs (power, money etc.).

But take a moment and let this sink in: Nearly every location depicted in this video is real. These arenít just fanciful places made up in the head of a special effect artist; those are worlds in our solar system that actually exist. And many were based on images taken through telescopes, or probes that have physically visited these distant locales.

Sunset on Mars. The weird ridge wrapped around Saturnís moon Iapetus. The ice fields of Jupiterís moon Europa. Even those cliff divers? Yup: thatís Uranusís moon Miranda, with the highest cliffs known in the solar system.

Every time the scene changed in the video, my jaw dropped a little further and my brain soared to a new height. Nothing in there is impossible; no faster than light travel, no wormholes. Even the space elevator shown towering over Mars and the huge cylindrical rotating colony in space (did you notice the Red Sea in it?) are problems in engineering, not physics. We can build them.

A new antibiotic - Teixobactin - has been discovered using a novel method. The antibiotic itself is limited to use against certain bacteria but has the advantage that it would be hard for the target bugs to develop resistance to it - source (http://pipeline.corante.com/archives/2015/01/08/teixobactin_a_new_antibiotic_from_a_new_platform.p hp).

It was discovered by taking a soil sample, suspending it in water then placing it in wells on a a chip and covered with semi-permeable membranes. It is then buried back in the soil it was removed from and left for a month. This helps to grow bugs that haven't been found under laboratory conditions. The new bugs are then tested against various strains that cause infections to see if it will kill them.

The author of this piece is an organic chemist and has given a bit of information for non chemists on why exploring the environment is still an important method of drug discovery.

As an aside, if you're outside the field, you might wonder why it's worth working so hard to find natural products when we have so many synthetic organic chemists in the world cranking out new compounds. One big reason is the ridiculous, insane hugeness of chemical space: the number of possible compounds at or under the molecular weight of teixobactin defies description, and I mean that in a completely literal sense. There are not enough resources on Earth, or in our entire solar system, to do enough organic synthesis to make any noticeable dent in that array. The idea of having compounds that bind to things like Lipid II is a good one, but they're going to have to be large compounds, and exploring that space is daunting.

And then there's the evolutionary factor. Bacteria are out there elbowing each other for space and nutrients every minute of the day, and they've been doing it for billions of years. They've had the time and motivation to come up with molecules that work to kill off their rivals, and we should take advantage of that legacy as much as we can. These molecules have not only had rigorous real-world tests of their mechanisms of action, they've also (perforce) had their properties optimized against their target organisms as well. Believe it, most large peptidic-looking things like teixobactin would have awful stability and pharmacokinetics as drugs. Finding the ones that don't is nontrivial indeed.

Totality is visible this time along a track a few hundred kilometres wide, which only intersects two landmasses, the Faroe Islands midway between Scotland and Iceland, and the arctic archipelago of Svalbard. Observers in those locations will see between two and two-and-a-half minutes of totality.

Away from the path of the total eclipse the Sun is only partly obscured by the Moon. This time the partial eclipse is visible across a large part of the northern hemisphere, including the whole of Europe, Greenland, Newfoundland, northern Africa and western Asia.
In London the partial phase of the eclipse begins at 08:25 GMT. Maximum eclipse is at 09:31 GMT when 85% of the Sun will be blocked. The eclipse ends at 10:41 GMT. Further north in the British Isles, observers enjoy an even better view. From Edinburgh 93% of the Sun will be covered and from Lerwick in the Shetland Isles, the Moon will obscure 97% of the solar disk.

One of the most effective advances in medicine, if not the number 1, is the introduction of vaccines. Small pox has been eradicated and several other diseases are all but gone in the developing world. New research has discovered an added advantage of the measles vaccine.

There is evidence to suggest that a measles virus infection resets your immune systems memory, leaving you vulnerable to other infections for up to 3 years after initially contracting the virus. After the introduction of the measles vaccine, there was a marked reduction in deaths, disabilities and hospitalisations, not just from measles but from other common infections too. In impoverished countries your chances of survival can increase as much as 90% (from exposure to infectious diseases).

In short, vaccines rule!

Researchers at MIT and Boston Children’s Hospital have developed a system that can take MRI scans of a patient’s heart and, in a matter of hours, convert them into a tangible, physical model that surgeons can use to plan surgery.

The models could provide a more intuitive way for surgeons to assess and prepare for the anatomical idiosyncrasies of individual patients. “Our collaborators are convinced that this will make a difference,” says Polina Golland, a professor of electrical engineering and computer science at MIT, who led the project. “The phrase I heard is that ‘surgeons see with their hands,’ that the perception is in the touch.”

Firedamp is a flammable gas found in coal mines that contributed to the deaths of hundreds of miners, who used open flames to light their way. Humphry Davy, a chemist at the Royal Institution, found a solution to the problem in 1815. He discovered that a flame could not penetrate a wire mesh, meaning that any explosions could be safely contained within a lamp if some metal gauze surrounded the candle.

Andy demonstrates in spectacular fashion exactly how this invention, which in many ways fuelled the industrial revolution, works, and celebrates a beautiful example of applied science in action.
