Coinciding with Easter Sunday, Glasgow Cannabis Social Club’s annual 420 event was held on Glasgow Green, under sunny blue skies, and overlooking the river Clyde. Despite the city’s council attempting to revoke permission for the gathering at the last minute, police were happy for it to go-ahead with approximately a dozen officers attending in high-visibility vests.

The Daily Record reported five arrests were made for minor offences, likely smoking and possession of small quantities of cannabis. Taking a less-sensational — and more accurate — line of reporting, the Monday edition of Glasgow’s Evening News stated five were referred to the Procurator Fiscal who is responsible for deciding if charges should be brought.

Official figures provided by the police were that 150 attended. With people coming and going, Wikinews reporters estimated upwards of 200 attended, compared to nearly 700 who had signed up for the event on Facebook. Hemp goods were advertised and on sale at the event, and some attendees were seen drinking cannabis-themed energy drinks.

“I was searched and charged under the Misuse of Drugs Act (which is a lot of bollocks)” one attendee noted online, adding “not fair to happen on a brilliant day like it was, other than that I had a great day!” A second said they were openly smoking and ignored by police, who “were only really focusing on people who looked particularly young”.

Cannabis seeds were openly and legally sold at the event and a hydroponics supplier brought a motortrike towing an advertising trailer. Actually growing cannabis is, however, illegal in the UK.

With the event openly advocating the legalisation of cannabis, speakers put their arguments for this to a receptive crowd. Retired police officer James Duffy, of Law Enforcement Against Prohibition, spoke of the failed United States alcohol prohibition policy; stressing such policies needlessly bring people into contact with criminal elements. Highlighting other countries where legalisation has been implemented, he pointed out such led to lower crime, and lower drug use overall.

One speaker, who produced a bottle of cannabis oil he had received through the post, asserted this cured his prostate cancer. Others highlighted the current use of Sativex by the National Health Service, with a cost in-excess of £150 for a single bottle of GW Pharmaceuticals patented spray — as-compared to the oil shown to the crowd, with a manufacturing cost of approximately £10.

Similar ‘420’ pro-cannabis events were held globally.

With two space walks, 78 million miles and six months on board the International Space Station under their belts, Commander-Science Officer Leroy Chiao and Flight Engineer Salizhan Sharipov, the station’s 10th crew, landed in Kazakhstan in a Soyuz spacecraft at 6:08 p.m. EDT Sunday.

Also returning was European Space Agency Astronaut Roberto Vittori of Italy, who launched to the Station with the Expedition 11 crew and spent eight days doing experiments. He was aboard under a contract between ESA and the Russian Federal Space Agency.

The re-entry of the ISS Soyuz 9 spacecraft was perfect, returning the astronauts to Earth 53 miles northeast of the town of Arkalyk after 192 days, 19 hours and 2 minutes in space for the Expedition 10 crew. The recovery team reached the capsule in minutes.

They launched from the Baikonur Cosmodrome in Kazakhstan last Oct. 13 at 11:06 p.m. EDT. During their increment they performed two spacewalks, continued station maintenance and did scientific experiments.

Notable accomplishments included replacing critical hardware in the Joint Quest Airlock; repairing U.S. spacesuits; and submitting a scientific research paper on ultrasound use in space. Chiao was also the first astronaut to vote in the U.S. Presidential election from space. The crew completed two spacewalks, including experiment installation and tasks to prepare the Station for the arrival of the new European Automated Transfer Vehicle next year.

Aboard the Station, Commander Sergei Krikalev and Flight Engineer and NASA Station Science Officer John Phillips, the Expedition 11 crew, are beginning a six-month mission. It will include the resumption of Space Shuttle flights and two spacewalks from the Station. Expedition 11 is scheduled to return to Earth on October 7, 2005. The two latest occupants of the station launched with Vittori from Baikonur April 14.

Krikalev and Phillips will have light duty for the next two days, as they rest after completing a busy handover period. For the past week, they have been learning about Station operations from the two men who called the ship home since October. Chiao and Sharipov briefed Krikalev and Phillips on day-to-day operations and gave them hands-on opportunities at Station maintenance. Chiao and Phillips restored the Quest airlock to working order for future spacewalks and practiced operating the Canadarm2 robotic arm.

Emergency hospital during 1918 influenza epidemic, Camp Funston, Kansas (source: National Museum of Health and Medicine, AFIP).

A bout of the flu can be mild. In young, healthy adults, many infections pass unnoticed. But sometimes the influenza virus evolves into a strain that decimates its victims. The worst known strain swept the world in the Fall of 1918, infecting 500-1000 million and killing 40-100 million, about 2-5% of people.

There are several theories about where the pandemic began, but the likeliest origin was in Haskell County, Kansas, in the United States. People in the sparsely populated county, where farmers raised pigs, poultry, cattle, and grain, began suffering from influenza in late January 1918. Unusually for flu, it was young, healthy adults who were hardest hit. Victims fell ill suddenly, many progressing to pneumonia and dying, often within days. Within weeks, however, the epidemic ended. The natural geographic isolation of this community normally might have contained the fatal flu in a sort of unintentional quarantine, but the First World War intervened. Men were uprooted from their home towns and congregated in huge numbers in army camps for training and then shipping out to other camps or to fight in Europe. The destination for men from Haskell County was Camp Funston, part of Fort Riley, Kansas, where the first influenza case was reported in early March. As soldiers moved among camps, the virus spread. Within two months, the epidemic spread to most of the army camps and most of the largest cities in the United States. As American soldiers went to France, so did the virus, spreading first from the port of Brest.

The flu then spread worldwide. The pandemic reached its height in the Fall of 1918. Spain was affected early, and because Spain was not fighting in the World War, there was no wartime censorship, and news of the outbreak became widely known, leading to the flu being called the Spanish Flu in many countries. In Spain, however, it was called French Flu or the Naples Soldier. In India, about 12 million people died of flu. In some US cities, people died so quickly that morticians couldn’t cope with the bodies. According to Jessie Lee Brown Foveaux, who worked in the Fort Riley laundry during the epidemic: “They were piling them up in a warehouse until they could get coffins for them.”

The disease started with cough, then headache. Temperature, breathing and heart rate increased rapidly. In the worst cases, pneumonia came next, the lungs filling with liquid, drowning the patients and turning them blue from lack of air. Patients bled from every orifice: mouths, noses, ears, eyes. Those who survived often suffered temporary or permanent brain damage. Several million developed encephalitis lethargica, in which victims were trapped in a permanent sleeplike and rigid state, as portrayed in the 1990 movie “Awakenings.” In others, normal thought processes were impaired. During negotiations to end World War I, US President Woodrow Wilson was struck with flu, and people around him noted that his mental abilities never fully recovered. The French leader George Clemenceau had wanted harsher punishment of Germany than Wilson had desired. Clemenceau may have convinced Wilson in his weakened state to accept such harsh terms, which may have been one of the factors causing World War II.

Since flu is highly contagious early in the illness, even before symptoms appear, strict quarantine may be necessary to stop its spread during an epidemic. Australia kept its 1918 flu death rate relatively low by enforcing quarantines. However, in many parts of the world, public health officials hesitated to impose such measures, giving the disease time to gain a foothold. In the US city of Philadelphia, a rally of half a million people was planned in September 1918 to sell bonds to fund the war, at just the time when the flu started to infect residents. Although doctors warned the public health director to cancel the rally, he wanted to meet the city’s quota to raise money for the war and refused to cancel the event. Within days after the rally, half a million city residents caught the flu.

Why was the 1918 flu so deadly? The influenza virus wasn’t preserved at the time of the outbreak, at least on purpose. But in the late 1990s researchers Ann Reid, Jeffery K. Taubenberger, and their colleagues extracted and sequenced the genetic material of the virus, RNA, from tissue of victims who died in the pandemic. They used bits of lung that were preserved in formalin from victims on army bases or from victims buried in permafrost in the Alaskan village of Brevig Mission, where flu killed 85% of adults. Comparisons with known flu viruses in humans, pigs, and birds suggest that some genes of the 1918 virus came from birds or an unknown animal source. Other scientists then were able to show that the amino acid sequence of hemagglutinin protein from the 1918 virus had several changes from other flu viruses that may have helped it to easily bind and invade human cells, and that made the virus look different enough from earlier flu virus strains that people had no immunity.

The possibility exists that another flu pandemic will sweep the world like the one in 1918. In 2004, an H5N1 influenza virus has killed millions of birds and at least 30 people in southeast Asia. So far this virus strain has not evolved the ability to pass directly from human to human, but that possibility becomes more likely as the bird flu pandemic continues and humans remain in contact with chickens, ducks, and other birds. The virus has killed two-thirds of people reported to be infected. Dr. Tim Uyeki, an epidemiologist for the US Centers for Disease Control, says, “you have the ingredients in Asia right now for a public health disaster.”

But since sequences of this bird flu virus are known, it may be possible to develop a vaccine or set of vaccines to protect against it. At a special meeting of influenza experts on November 11th and 12th, World Health Organization influenza program chief Klaus Stohr said, “It is not only possible, but also important, that influenza pandemic vaccines be made available… and there’s a shared responsibility needed to make that happen…. We have a huge window of opportunity now.”

Last month, a study conducted by archæologist Dr. Naomi Martisius and other researchers concluded Neanderthals living in Europe tens of thousands of years ago were more sophisticated than previously thought. The now-extinct species used to carefully select bones from a particular animal species to manufacture their bone tools, the research showed. The research was published on May 8 in Nature’s Scientific Reports journal.

Dr Martisius and her team used five bone tools discovered from Neanderthals’ sites in southwest France for this research. Four of these bone tools were found in a site called Abri Peyrony and the other one was from Pech-de-l’Azé I. These tools were just a few centimetres in size and were about 50 thousand years old, Dr Martisius told Wikinews. Microscopy analysis of these bone tools called lissoirs (smoothers) suggested Neanderthals used these tools for working animal skin to leathers.

The study stated the fauna of the sites were primarily medium-sized ungulates such as reindeer, in one layer nearly 90%. Despite the overabundance of medium-sized ungulates, Neanderthals used ribs of large bovids for making lissoirs. Dr Martisius told Wikinews this was likely due to the physical characteristics of the bovid ribs, which were “thicker” and “stronger” as compared to the “thin and flimsy ribs” of reindeers. In order to check the origins of the bone tools, the researchers used a technology called non-destructive Zooarchæology by Mass Spectrometry (ZooMS).

Instead of damaging the bone artefacts in order to discover its origins, the researchers collected collagen from the plastic containers in which these artefacts were kept. Collagen is a type of protein. These bone artefacts were kept in plastic containers: some were kept for about five years, some for just a few months. During this time, the collagen proteins from bone tools were stuck to the walls of its plastic containers. The collagen samples collected from the walls of the containers are broken into smaller molecules called peptides by using a chemical enzyme called trypsin.

After the trypsin has broken collagen fibres into peptides, it is analysed using a technology called Matrix-assisted laser desorption/ionization (MALDI) Time-of-Flight mass spectrometer (ToF MS). The assisting matrix is a coloured compound. The acidic peptide is combined with the matrix, vapourised, and peptides are released. Some of them are positively-charged particles which travel across a vacuum tube in an electric field. Depending on the weight of the peptides, these molecules reach the end of the vacuum tube at different instances of time, forming a spectrum. These graphs are like unique fingerprints of a species: they are different for different species of animals. Looking at the database of such graphs, taxonomic identifications of the collagen proteins came be made.

All four bone tools from Abri Peyrony gave positive results and showed that the bones were made from large bovids, even though reindeer were more abundant during that time. One of the advantages of using bovid ribs over reindeer’s thin ribs was the bovid ribs would be more resistant to breaking during flexion, Dr Martisius said.

Dr Martisius said such non-destructive ZooMS analysis was previously conducted, but for tools no older than a few centuries. She said such an analysis had never been previously conducted for artefacts so ancient.

Wikinews caught up with Dr Martisius to discuss this research in-depth.

On June 3rd, 2008, two United States Internet service providers (ISPs) announced they would begin tests to slow web access for their most active customers and charge them for extra speed. Comcast and Time Warner Cable, two of the largest ISPs in North America, both made separate announcements of their plans. The actions come in the wake of an investigation by the Federal Communications Commission (FCC), over whether Comcast had restricted some customers from sharing videos, music, and similar files. The FCC investigation led to a US Congress debate over whether and how much control ISPs should have over the flow of customer data.

Public interest groups complained in November 2007 to the FCC that Comcast had specifically targeted customers using applications that made use of the BitTorrent system, a popular form of file sharing. Free Press, an advocacy group that pushes for better oversight of cable operators such as Comcast, stated that Comcast practices were discriminatory towards users of the legal technology. “The cable companies see a hammer hovering above their heads and are scrambling to find ways to reduce the appearance of wrongdoing,” said Ben Scott, head of the group.

According to Roger Entner, a senior vice president from Nielsen IAG, as little as 5 percent of all Internet users may consume as much as 50 percent of all the bandwidth on the Internet. “This is the politically correct version of doing what Comcast had been doing before, though it takes the occasional [peer-to-peer] user off the hook,” Entner said. Sena Fitzmaurice, a Comcast spokesperson, said, “This says we won’t be looking at what type of traffic that there is, even though we still need to manage the network.”

Comcast’s tests are expected to begin in Chambersburg, Pennsylvania and Warrenton, Virginia.

While Comcast will attempt to throttle the speed of all its high-volume users, Time Warner Cable intends to use a different method. They will meter and bill clients, charging more money for faster speeds and larger amounts of transmitted data, functioning more like a traditional public utility, such as an electric company or cell phone service. Their metered billing test will begin on June 5 in Beaumont, Texas for newly enrolled customers. “Instead of raising prices across the board, consumers who are excessive users would pay,” said Alex Dudley, a Time Warner Cable spokesman. “It is clearly the fairest way to fund the investment that is going to be required to support that use.”

An Associated Press report that Time Warner Cable will bill customers between $29.95 to $54.90USD per month has been confirmed by the cable operator, with clients charged an extra $1 for each gigabyte (GB) by which they exceed their purchased plan. Art Brodsky, communications director of Public Knowledge, a consumer advocacy group in Washington D.C., has expressed concerns about the Time Warner Cable plan. Time Warner Cable’s most expensive offering, $54.90, comes with 15 megabits-per-second of data transfer speed and a 40 gigabyte limit on total data transfer.

“An HD (high-definition) movie is 8GB or so, three movies is more than half your allowance for a month, and heaven knows what else you might want to watch,” Brodsky says. “This is not a relieving congestion scheme as much as it is a rationing scheme. All it does is protect an inadequate infrastructure from the cable company.”
