  1. What we can learn from God's creative works with regard to living creatures.
  2. Try squeezing a banana and a mess will squirt out from its ends. But what happens to Miura-ori when you throw in a few defects? By reimagining the kinks and folds of origami as atoms in a lattice, researchers are uncovering strange behavior hiding in simple structures. The Atomic Theory of Origami (Quanta Magazine)
  3. Scientists at Imperial College London gave psilocybin, the active ingredient in magic mushrooms, to 20 patients who had depression that hadn’t been helped by other treatments. Patients first took a 10mg dose of psilocybin, then a 25mg dose the week after. All the patients said they still felt better a week after treatment, and about half of them felt better five weeks later, too. These self-reports were confirmed by before-and-after brain scans. After the treatment, there was less blood flow in the part of the brain that is involved in emotion processing, called the amygdala. Interestingly, scans of the brain while on drugs show a type of “disintegration” where there’s less connectivity between different parts. Researchers have suggested that this disintegration is responsible for why people report losing their sense of self or ego while on drugs. But the scans of the brain afterward found that there’s more connectivity and integration, suggesting that maybe psychedelics work by breaking down the old pattern and kickstarting the brain into a new one. Magic mushrooms might help depression by resetting the brain (The Verge) Psilocybin for treatment-resistant depression: fMRI-measured brain mechanisms (Nature)
  4. Man Partly Wakes From 15-Year Vegetative State—What It Means After a person spends a year in a vegetative state, the condition is considered permanent—there will never be someone “in there” again. That’s why it’s so surprising French researchers were able to boost the consciousness of a patient who had spent 15 years in a vegetative state following a car accident. Brains aren’t supposed to work that way. (National Geographic)
  5. Ancient fossils in African cave are tantalizing glimpse of early man One of the richest collections of early-human fossils ever found has been hauled out of an African cave, thanks to the efforts of a handpicked team of scientists slender enough to fit through ancient narrow passageways, researchers announced today. http://www.wkyc.com/story/news/2015/09/10/fossils-humans-cave-ancient-bones/71966570/
  6. I'd like to share an interesting site from the University of Manchester, that allows you to create your own earth in three forms - recent earth, ancient earth and alien earth. Using parameters such as temperature, climate, tilt etc, the program models what the planet would have been like. In the case of recent earth, it shows a snapshot of what our planet was like, say in 1975. That's useful in itself for showing the changes on earth in our lifetime. I find this fascinating! I hope someone here will too. It's not too complicated, and I've included the lecture notes for the instructions and interpretations from the modelling. http://www.buildyourownearth.com/ https://www.dropbox.com/s/icckq0vx820rqwa/Build%20Your%20Own%20Earth.pdf?dl=0
  7. Spanish newspaper La Razón has published today an interview with Russian physicist Andrei Linde, who proposed in 1983 a Big Bang refinement known as "cosmic inflation theory". The reason for the interview is that now, thirty years later, some evidence has been found that seems to confirm his hypothesis, so he's likely to be awarded the Nobel prize on Physics. I found interesting some of his comments about religion. (I haven't been able to find this interview in any newspaper in English, so I'm translating from Spanish). Even though he is not a religious person, he admits there are some questions science has no answers for. "We don't know how to explain the simple fact that we are alive, the meaning of pain or happiness, or what is it that makes us all alive, or the meaning of all of that in general", he declared. "I think we will ultimately try to understand all those questions at the same time our knowledge about the universe grows, and maybe at that point we will have a wide vision", he added. "It's not that we want to deny the existence of someone superior to our own intelligence, we only want to explore all the easier possibilities first", he explained.
  8. Sounds about right. However 48% don't know man came about by (D)evolution either Wonder where they think we came from? Did notice article is from down under http://www.news.com.au/technology/science/in-4-americans-unaware-that-earth-circles-sun-poll/story-fnjwlcze-1226828958882
  9. Very Interesting Fibonacci numbers found in human hand & arm. Is Jehovah marvelous or what! Humans exhibit Fibonacci characteristics, too. The Golden Ratio is seen in the proportions in the sections of a finger. It is also worthwhile to mention that we have 8 fingers in total, 5 digits on each hand, 3 bones in each finger, 2 bones in 1 thumb, and 1 thumb on each hand. The ratio between the forearm and the hand is the Golden Ratio! http://jwilson.coe.uga.edu/emat6680/parveen/fib_nature.htm
  10. http://www.theverge.com/2013/8/13/4617750/regenerative-medicine-breakthrough-lab-grown-human-heart-tissue Progress in regenerative medicine has been coming fast and furious in recent months: scientists are now using far-out tissue engineering techniques to restore liver function in mice, regrow human muscle, and even implant bioengineered blood vessels into ailing patients. Now, a team at the University of Pittsburgh has managed to grow human heart tissue that can beat autonomously in a petri dish — an exciting step towards devising transplantable replacement organs. The group, who reported their progress in the journal Nature Communications, used induced pluripotent stem cells (iPS cells) to accomplish the feat. These mature human cells are first "reprogrammed" to an embryonic state, before being spurred to develop into a specialized type of cell. In this instance, iPS cells derived from human skin were induced to become multipotential cardiovascular progenitor (MCP) cells — basically heart cells that can further differentiate into three varieties of highly specialized cells required for cardiovascular function. From there, scientists transplanted the cells onto a mouse heart that had been completely stripped — turning the organ into what's known as a "scaffold." Over a period of weeks, the transplanted human cells proliferated and differentiated, rebuilding the scaffold into a functional organ capable of beating on its own. Right now, the heart tissue contracts at a rate of 40 to 50 beats per minute (on-par with a human's resting heart rate) but needs to be further refined before it's capable of beating strongly enough to distribute blood, or speeding up and slowing down when necessary. This isn't the first time that scientists have managed to engineer heart tissue — in recent years, other teams have created lab-grown beating rat hearts and even human heart tissue. The latter breakthrough, however, relied on embryonic stem cells, which can't be derived from a specific patient for subsequent, personalized transplant the way this new technique allows. A full-sized, fully functional replacement human heart is, of course, several years off. But in the near future, scientists hope to develop personalized "patches" of human heart muscle to repair damaged organs, and hope to see their technique used to more accurately study the effects of new pharmaceuticals to treat cardiovascular ailments.
  11. http://www.popularmechanics.com/how-to/blog/what-created-these-mystery-radio-waves-from-another-galaxy-15657576?click=pm_latest CSIRO's Parkes radio telescope, which has been used to confirm a population of Fast Radio Bursts, is shown superimposed on an image showing the distribution of gas in our Galaxy. Credit: Swinburne Astronomy Production. A single, gleaming flash of radio waves zooms toward us from halfway across the universe. Where it came from, nobody was sure, and it was gone in an instant. The Lorimer burst, named after the astronomer who discovered it in a stack of half-a-decade old records, has stumped scientists for the last six years. But today a team of astronomers has announced that they’ve found four more flares just like it. "You have to look at the sky for a very long time to find these," says Dan Thornton, the astrophysicist at the University of Manchester who discovered the new radio wave bursts. "The reason that we’re detecting them now is we’ve simply looked long enough." Thornton and his colleagues have just published a paper in the scientific journal Science saying that these strange radio wave bursts are an entirely new astronomic phenomenon. "Some people actually suspected the Lorimer burst was an atmospheric event," and a fluke measurement, says Manjari Bagchi, an astrophysicist at the International Centre for Theoretical Sciences, in Bangalore, India, who has also searched for these radio wave flares but was not part of the study. "But this proves that these are all natural phenomenon," Bagchi says. Each flash of energy lasts only a few milliseconds, and researchers still don’t know what causes them. "We think they’re probably caused an explosive event, because we haven’t seen them repeat," Thornton says. And pinpointing their exact origin is just about out of the question, given how rare they are and how big space is. Thornton and his colleagues think a good bet for the burst’s beginnings might be magnetars, which are rare and incredibly dense husks of past supernovae that are prone to occasional explosions of energy. "A magnetar can give off more energy in a millisecond than the sun in 300,000 years," Thornton says. Whatever created them, Thornton’s radio wave bursts hail from so far away that that they’ve taken half of the universe’s life to reach us. "That’s halfway to the big bang," Thornton says. That long travel leaves its mark on the radio waves: As the waves pass through charged particles in space, they’re stretched out slightly. Thornton believes that even though we don’t know the cause of the flares, by measuring that stretch and studying more of them, "we can use them to probe the material between us and the big bang."
