Sent there recently by California high school students to measure the radiation from a solar storm. Details here. I wish my high school science projects had been that cool. Instead, they were all intensely boring. The only one I even remember was a water electrolysis experiment that I had to work on for weeks, and which involved the edge-of-your-seat thrill of watching a battery split water into hydrogen and oxygen.
Dutch artist Berndnaut Smilde creates temporary clouds inside rooms by regulating the temperature and humidity inside the rooms.
When I saw this it immediately reminded me of an experiment conducted in the eighteenth century by the Dutch scientist Martin van Marum. He created two artificial clouds by filling calf's bladders with hydrogen, causing them to float around his laboratory. He gave one of these bladder-clouds a positive charge, and another a negative charge. As these charged clouds floated around, sparks would pass between them. This was Van Marum's way of simulating a lightning storm.
But van Marum had an extra trick that was always a great crowd pleaser. He introduced a third (non-charged) cloud into the room. When this non-charged cloud passed between the two charged ones as they were exchanging sparks, it would noisily explode into flames (kinda like a miniature Hindenburg). That's how to do an interior cloud installation properly!
When Iranian national Golshifteh Farahani decided to take a stand against Iran's notoriously strict rules for women, she wanted maximun exposure. So what better way for the Paris based actress to show Ahmedinejad the finger than to show a whole lot more than than, by posing naked for a French magazine. Well it certainly got their attention (plus the attention of a many others judging by the huge upsurge in visitors to her Facebook page from her home country), the Iranian government has banned her from ever returning home. According to Ms. Farahani, an official from Iran's Ministry of Culture told her that Iran didn't need any actors or actresses, which was especially ironic since Iran won it's first ever Golden Globe award this year for the film "A Separation" (The Independent).
From the nude to the rude now, as popular British daytime quiz “Countdown” stirred up a bit of controversy this week when a contestant won one round with the word “wanker”. The object of the game is to make the longest possible word from a random selection of vowels and consonants in just 30 seconds, and in this particular round this meant the letters RAEPKWAEN. Mark Murphy’s six letter offering left host Nick Hewer at a loss for words, but was the longest and is in the dictionary, hence took the round after his opponent could do no better than 5. Clearly though “wanker” shouldn’t have netted Mark the points, he could have had “reawaken” for eight (Orange).
A slightly more pleasant shock greeted teacher Parijat Saha from Dinajpur in India when he checked his bank account online one evening. In a classic Monopoly moment, a bank error in his favour gave him a balance of 490 billion rupees (about $9.7 billion). Mr. Saha promptly rang the State Bank of India to report the mistake, joking that the bank appeared to have so much money it was overflowing into his account. A bank spokesman later claimed that the funds were uncleared, and in any case couldn’t have been withdrawn (Digital Spy).
Finally, a three-night astronomy special on British television scored two spectacular successes this week. The BBC show “Stargazing Live”, hosted physicist Brian Cox and comedian Dara O’Briain live from Jodrell Bank, encouraged viewers to get more involved with astronomy, both from their gardens and online, and has led to a 500% surge in telescope sales in the UK in the last few days, but more spectacularly, one viewer may have actually discovered a new exo-planet after visiting a website featured on the show. Chris Holmes was one of sixty thousand people who were inspired to visit planethunter.org after watching the show, and despite having no more than a passing interest before, he identified a possible eclipse of the star SPH10066540 by a Neptune sized object in a 90 day orbit (BBC News).
Back in March, patty reported here on a Chinese man who – after being born without one – received a surgically constructed artificial anus. Now scientists have gone one better and actually grown a working anal sphincter in the laboratory. The team, who hail from Wake Forest Baptist Medical Center, grew the artificial orifices from cultured human muscle and nerve cells in about six weeks. Then, to test if they worked, the sphincters where implanted in laboratory mice. Ultimately, the scientists hope a patient’s own muscle and nerves could be used to create ‘personalized’ replacements, avoiding any immune response. In the near future, the “test tube” anus could be a boon for both the faecally incontinent and former porn stars alike (CBS News).
But an artificial exit may be just the start, as scientists are now one step closer to understanding the development of the entire intestine, in this case, why it coils the way it does. A rare collaboration between Harvard’s Medial and Engineering schools finally untangled the problem of why the intestine coils so predictably during the growth of the foetus while essentially unconstrained. Previously it had been thought that growth of the gut might be being restricted by the abdomen, but that didn’t explain why nearly everyone’s intestines fold into exactly the same shape. Then a chance conversation led Harvard Professor of Applied Mathematics, L. Mahadevan, to suggest a simpler hypothesis, the gut and its connective tissue, called the mesentry, grow at proportionally different rates. Now two teams, led by engineer Thierry Savin and biologists Natasza Kurpios and Amy Shyer, have confirmed that insight with a combination of computer and physical models and experiments, finally unravelling what makes our insides so loopy (Science Daily).
And speaking of loopy, what would you prescribe to someone with chronically inflamed bowels? Well for a growing number of people, the best medicine is a healthy(?) dose of parasites. The parasites in question are whipworms, also known as helminths, hence the name of the process, helminthic therapy. It has been known for over a century that some parasite infestations seem to reduce the symptoms of other diseases, but it is only fairly recently that any serious study has been made into why this is so. The current hypothesis is that the worms, which live in the human intestine, partially suppress the host’s immune response to protect themselves, and in doing so prevent the aggressive autoimmunity behind conditions such as Crohne’s disease and IBS, and so far the results have been startlingly good. However the success of the treatment is causing its own problems as some sufferers are refusing to wait on the medical establishment and are treating themselves by deliberately swallowing doses of the parasites’ eggs obtained over the internet. The worry for some is that the parasites, which are naturally infectious, might spread to very young or otherwise vulnerable people where they might have more serious effects (University of Massachusetts (PDF)).
Yet as one weird treatment rises, another shall fall. Colonic irrigation, the practice of repeatedly flushing out your lower intestines with water or various herbal infusions, has no medicinal benefit according to a study by doctors from the Georgetown University School of Medicine. Moreover, it can actually be harmful, carrying not just a risk if perforation of the bowel, but a list of side effects that range from intestinal cramps and nausea to renal failure. The team, lead by Dr. Ranit Mishori, looked at over 20 studies carried out in the past 10 years and found little to no evidence of any health improvements associated with the treatment, but a litany of problems, including cases of anaemia and increased liver toxicity. She also highlighted the dangers from poorly trained and regulated operators performing the procedure, and from “do-it-youself” detoxing kits that often combine a less invasive form of the therapy with strong laxatives (The Independent).
