"The Stanford torus was proposed during the 1975 NASA Summer Study, conducted at Stanford University, with the purpose of speculating on designs for future space colonies (Gerard O'Neill later proposed his Island One or Bernal sphere as an alternative to the torus). "Stanford torus" refers only to this particular version of the design, as the concept of a ring-shaped rotating space station was previously proposed by Wernher von Braun and Herman Potočnik.It consists of a torus, or doughnut-shaped ring, that is 1.8 km in diameter (for the proposed 10,000 person habitat described in the 1975 Summer Study) and rotates once per minute to provide between 0.9g and 1.0g of artificial gravity on the inside of the outer ring via centrifugal force." - Mark H from Bookmarklet
"Sunlight is provided to the interior of the torus by a system of mirrors. The ring is connected to a hub via a number of "spokes", which serve as conduits for people and materials travelling to and from the hub. Since the hub is at the rotational axis of the station, it experiences the least artificial gravity and is the easiest location for spacecraft to dock. Zero-gravity industry is... more... - Mark H

Building Blocks for a Generation Ship
"Project Hyperion is working on the first ever design of a manned interstellar vessel. Recently, the team thought about how to leverage on existing heritage for the spacecraft’s subsystems. In particular, two major elements of a crewed spacecraft were of particular interest: the propulsion system and the habitat. A preliminary analysis has already been done by the team about two years ago" - Mark H from Bookmarklet
"Options for the propulsion system included Daedalus, Project Icarus’ Ghost Ship, as well as laser sails. For the habitat, various O’Neill colony designs, the Stanford Torus, as well as the 1976 MIT space colony design and the National Space Society’s Kalpana One colony were considered. Based on these criteria, the current Project Icarus, Ghost Team’s design was chosen for the... more... - Mark H

Bosnia's wartime rape survivors losing hope of justice
"In the garden of a women's refuge overlooking the plant, Lejla describes the brutality she suffered as a teenager. "I was 14 and living with my grandmother when the war began," she says. "I was captured and spent three years in a prison camp, where we were forced to do manual labour. Later, I was separated from the rest of the prisoners along with three other women and taken to a house. "The soldiers would drink. We would have to serve them like slaves and they would rape us." Estimates for the number of women like Lejla who were subjected to sexual violence during the Bosnian War range from 20,000 to more than 50,000." - Mark H from Bookmarklet
"Men were also raped during the Bosnian War, often as a means of humiliation. Zihnija, a former soldier in the Bosnian army, shakes visibly as he recounts what happened to him. "The military police took me to a basement and beat me unconscious," he recalls. "When I woke up, one of the officers took a shovel, ripped my trousers and put it inside me. Then they threw me back on the floor.... more... - Mark H
So horrible that governments always sweep the sexual violence war crimes under the rug. Too many forget it's not just the soldiers who get scarred. - Anika
Bring back any memories Slippy? Went around the Tricorn exhibition in the city museum today. Great to see these pieces of a wonderful example of brutalist architecture sadly no longer around.

"In 1986 it was reported that [Jenny lives with Eric and Martin] was in the library of a school run by the Labour-controlled Inner London Education Authority, and this was a major factor in the Tory government passing Section 28 of the Local Government Act, which prohibited the ‘promotion’ of homosexuality." Looks like we've just got to give Russia and chunks of Africa about 30 years to catch up then. - Mark H from Bookmarklet

"There are many reasons why you might start a blog, but documenting the revival of an 18th century neoclassical ruin seems like a pretty damn good reason if you ask me. In 2013, Australian husband & wife team Karina and Craig Waters purchased the Chateau de Gudanes, a decaying fairytale mansion in the Midi-Pyrénées that had been sitting on the market for four years." - Mark H from Bookmarklet

Regarding Our Zoo's Rebranding as "The Insane Horror Zoo"
"We understand that it can be upsetting that we are killing all these beautiful animals. To be honest, we don't like to do it much, but it is part of our rebranding effort that we announced to members last year. Since zoos around the world have undertaken efforts to become more humane, our own efforts to provide lifelike habitats, ample space, and comfortable interaction with patrons no longer really set us apart. That is why these "culls" are part of the larger plan to rebrand the Copenhagen Zoo as "The Insane Horror Zoo."" - Mark H from Bookmarklet
"We want to create brand synergy by wasting tons of animals. We will become the Hostel of zoos. We will do anything to these animals. We will ice a panda. We will do a hit on a python. If you can't hang with this, you need to get out now, because the carnage has only begun. Our 2014 schedule of animal death is just getting warmed up." - Mark H

Homeopathy product recalled over fears it may contain actual medicine
"A company making homeopathic remedies in the US has had to recall more than 50 different products from across its range after they were found to contain actual medicine. Terra-Medica, based in Ferndale, Washington, promises to provide “a wealth of education and high quality health products [to] holistic health care practitioners across the US”." - Mark H from Bookmarklet
"Yet in a series of tests by the US Food and Drug Administration (FDA), it was found that a variety of tablets, capsules, drops and suppositories – with names like “Pleo-QUENT” and “Pleo-STOLO” – actually contained quantities of penicillin. [...] [Homeopathy] involves the practice of massively diluting active ingredients with large quantities of water, and has since been extensively... more... - Mark H

Fusion reactor wall manages unexpected shielding against extreme heat loads
""During the simulated ELM pulses, we saw a completely counterintuitive behaviour", says de Temmerman: "The more power we sent to the wall material, the less energy actually reached the surface. The temperature of the tungsten samples already peaked part-way through the energy pulse and then started to drop. At the same time, our fast camera saw Hα-light coming from near the surface." Hα-light is a spectral line that indicates that cool hydrogen gas has escaped from the tungsten wall surface. De Temmerman: "We already know that the metal tungsten can absorb limited amounts of hydrogen, like a sponge. It looks like the incoming energy pulse frees a cloud of this absorbed hydrogen from the tungsten. The gas blanket then sucks energy from the incoming power pulse and distributes it evenly, protecting the surface directly below it." Simulations of the hydrogen stored in the tungsten before and after a plasma pulse support this analysis." - Mark H from Bookmarklet
"Fusion researchers try to recreate nuclear fusion, the power source at the heart of the sun, as a sustainable energy source on Earth in tokamak reactors like ITER. In a fusion reactor, hydrogen nuclei collide at hundreds of millions degrees Celsius, then fuse together to form helium and release prodigious amounts of energy. ITER has been designed to demonstrate the technical... more... - Mark H

"If you’ve ever watched a Star Wars space battle and thought, man, I want to be there, playing Elite: Dangerous with the Oculus Rift is as close as you can currently get. Elite has always been prized as a freeform, open-world RPG, so I really wasn’t expecting this Kickstarted update to be one of the most tactile, kinetic and convincing sims I’ve yet played. I’ve never flown a real spaceship, but playing this with a flight stick feels exactly how I imagined being in the cockpit of an X-Wing would be." - Mark H from Bookmarklet
Already planning a future US trip which involves flying into Chicago and driving to Cleveland then onto Maryland (within easy reach of Washington DC). First thing my missus says when I outline that plan: "Does this mean we can eat some food with Derrick?" Yeah, there's a chance that could happen.

"Forget the disco era, the 1970s in New York City was all about danger. With pimps and prostitutes populating the streets, an economic collapse and a crime-filled subway system, the streets of Manhattan were gritty and dark.
