ASU cosmologist suggests studying moon for alien artifacts

first_img Though some might see it as farfetched, or heaven forbid, lunacy, Davis and Wagner are convinced that it’s worth the small amount of investment such a search would entail. What if, they suggest, close-up photographs of the moon that are already being made available to the masses (from NASA’s Lunar Reconnaissance Orbiter) via the Internet, were to be presented with a request that anyone that would like to participate, study whichever photos they find interesting, looking for anything that appears of unnatural origin, then report back. Interesting “finds” could then be studied by many others, and those that seem promising could be studied further by professionals. It all seems so easy, after all, other group projects are underway, and by most accounts, appear to meet with relative success.Another possibility, the team suggests, is using image or shape recognizing software to scan photos of the moon to help narrow down search areas and to alert humans when it finds something interesting.The idea of putting resources towards searching for the existence of intelligent alien life wouldn’t be new of course, the SETI project exists for that sole purpose. Looking for evidence that we’ve been visited by an extraterrestrial is of course a little different, but in this case, it seems to make sense. After all as Davis and Wagner point out, because the moon is so barren, has no atmosphere and because it is so seldom hit with meteorites, things that go on there are preserved for tens or even millions of years. If any aliens visited the moon during that time span, it should be possible to find traces of their activity, or their equipment, offering proof for the very first time, that there really is someone else out there. New calculations suggest Jupiter’s core may be liquefying (PhysOrg.com) — If you were part of a team sent to explore an unknown planet; and that planet had a natural orbiting moon, wouldn’t it make sense to use that moon as a base camp or remote observation post? Especially if you didn’t want those being observed to know you were there? Professor Paul Davis and research technician Robert Wagner think so, and that’s why they’ve published a paper in Acta Astronautica that suggests we humans begin taking a little closer look at our own moon to see if any alien life forms might have left behind some evidence of their visit. More information: Searching for alien artifacts on the moon, Acta Astronautica, In Press. doi:10.1016/j.actaastro.2011.10.022AbstractThe Search for Extraterrestrial Intelligence (SETI) has a low probability of success, but it would have a high impact if successful. Therefore it makes sense to widen the search as much as possible within the confines of the modest budget and limited resources currently available. To date, SETI has been dominated by the paradigm of seeking deliberately beamed radio messages. However, indirect evidence for extraterrestrial intelligence could come from any incontrovertible signatures of non-human technology. Existing searchable databases from astronomy, biology, earth and planetary sciences all offer low-cost opportunities to seek a footprint of extraterrestrial technology. In this paper we take as a case study one particular new and rapidly-expanding database: the photographic mapping of the Moon’s surface by the Lunar Reconnaissance Orbiter (LRO) to 0.5 m resolution. Although there is only a tiny probability that alien technology would have left traces on the moon in the form of an artifact or surface modification of lunar features, this location has the virtue of being close, and of preserving traces for an immense duration. Systematic scrutiny of the LRO photographic images is being routinely conducted anyway for planetary science purposes, and this program could readily be expanded and outsourced at little extra cost to accommodate SETI goals, after the fashion of the [email protected] and Galaxy Zoo via The Guardian Moon.

Researchers use magnets to cause programmed cancer cell deaths

first_img Citation: Researchers use magnets to cause programmed cancer cell deaths (2012, October 8) retrieved 18 August 2019 from https://phys.org/news/2012-10-magnets-cancer-cell-deaths.html More information: A magnetic switch for the control of cell death signalling in in vitro and in vivo systems, Nature Materials (2012) doi:10.1038/nmat3430AbstractThe regulation of cellular activities in a controlled manner is one of the most challenging issues in fields ranging from cell biology to biomedicine. Nanoparticles have the potential of becoming useful tools for controlling cell signalling pathways in a space and time selective fashion. Here, we have developed magnetic nanoparticles that turn on apoptosis cell signalling by using a magnetic field in a remote and non-invasive manner. The magnetic switch consists of zinc-doped iron oxide magnetic nanoparticles5 (Zn0.4Fe2.6O4), conjugated with a targeting antibody for death receptor 4 (DR4) of DLD-1 colon cancer cells. The magnetic switch, in its On mode when a magnetic field is applied to aggregate magnetic nanoparticle-bound DR4s, promotes apoptosis signalling pathways. We have also demonstrated that the magnetic switch is operable at the micrometre scale and that it can be applied in an in vivo system where apoptotic morphological changes of zebrafish are successfully induced.

The application of the magnetic field, as described in their paper published in the journal Nature Materials, triggers a “death signal” that leads to programmed cell death. last_img read more

Delhis date with asardar sardars

first_imgSunday evening, it was west Delhi’s turn to hog the limelight. The highlight of the day? A stand-up act called  A’Sardar, which was a comedy gig presented by two most funniest sardars — Maheep Singh and Vikramjit Singh.The performance was a part of the ongoing Atelier ACT Festival which is a workshop of communication enthusiasts who have been organising creative educational programmes and devising socially relevant plays. It has conducted various workshops on creative teaching and creative learning. Also Read – ‘Playing Jojo was emotionally exhausting”We are continuously devising and designing specific learning enhancement programmes for special educators and are incorporating creative drama and theatre-in-education techniques,’ said a member of the group.’A’sardar, the word itself has a dual connotation. It refers to asardar (catalyst to change) sardars. Dedicated to the ones who are performing and the ones who are witnessing it. We are sardars but not the usual typical ones,’ said Maheep.His act mostly took a dig at regular mishaps in a Also Read – Leslie doing new comedy special with Netflixsardar’s life. Like how a sardar is always greeted by specific terms like balle balle or paaji instead of his regular name or how he gets served sarso ka saag and makke ki roti even in an Italian restaurant and how he is much scarier than a scarecrow (toy) to horrify little children to manage them,’ laughed Maheep.Vikramjit’s act on the other hand started with a disclaimer note claiming — the jokes today are offensive but you need not worry since they are in English. He tickled the funny bone with his uncanny yet humourous remarks on fitness freaks seen at gyms, how shopping is not a natural thing (unlike what women call it) which should be solely replaced by lots of sex and food (much natural and pleasurable) and the advertisements on TV.Vikramjit has been doing stand up for over an year now, and says that he derives his punches from the daily problems he deals with in life.’Instead of ruminating over them, I make a joke out of them. Just like how batting comes to Sachin,’ Vikramjit said.’Comedy for me is being in the moment and suit according to the scene. I am a big believer in laughing at oneself. Then only you can succeed in bringing a few laughs,’ Maheep signed off.last_img read more

Marilyn Monroes final photoshoot to be auctioned

first_imgRare photos of screen icon Marilyn Monroe, taken just weeks before her untimely death, are going to auction in London. The stunning snapshots were taken by her friend, photographer George Barris, on Santa Monica beach on July 13, 1962, just three weeks before she was found dead at 36 in her Los Angeles bedroom.Eight of the prints, several of which show Monroe romping on the beach in a towel or bikini, are expected to sell for 8000 pound at Dreweatts & Bloomsbury Auctions in London on June 4.Barris, who met Monroe in 1954 on the set of her hit film The Seven Year Itch, originally intended to use the pictures for a book he was working on about the iconic actress, but he scrapped it after her death. In 2001, Barris published a book called Marilyn: Her Life in her Own Words: Marilyn Monroe’s Revealing Last Words and Photograph.last_img read more
