On Wednesday, NASA scientists said that, unlike green plants on the planet Earth, plants on other planets may be the color red or yellow.

Plants on Earth are green because they contain chlorophyll. The chlorophyll appears green because it absorbs mainly blue and red light in order to produce food for the plant via photosynthesis, while reflecting the green light frequency.

Scientists at NASA point out that if the stars for other planets were in a different state than our sun and if the light frequency that reached the planets’ surface was different, then the plants on those planets would have also evolved a different type of photosynthetic pigment other than chlorophyll. This pigment would be dedicated towards the different light frequencies received by the planet causing the plant to appear a different color from green such as red and yellow.

Carl Pilcher, director of the NASA Astrobiology Institute, said, “This work broadens our understanding of how life may be detected on Earth-like planets around other stars, while simultaneously improving our understanding of life on Earth. This approach–studying Earth life to guide our search for life on other worlds–is the essence of astrobiology.”

The research into the color of plants on other planets was started by California Institute of Technology astrobiologist Vikki Meadows and a host of other scientists who were studying how light is absorbed and reflected by plants and some bacteria on Earth. Using this data, a computer model was designed to predict the color of plants and bacteria on other planets.

Nancy Kiang, a biometeorologist at NASA’s Goddard Institute for Space Studies, noted that it was unlikely any of the plants would be the color blue, “It appears that harvesting blue light is very common across the board for photosynthetic organisms. I think it is unlikely that anything will be blue.”

Wikinews accredited reporter Killing Vector traveled to the G-20 2009 summit protests in London with a group of protesters. This is his personal account.

London — “Protest”, says Ross Saunders, “is basically theatre”.

It’s seven a.m. and I’m on a mini-bus heading east on the M4 motorway from Cardiff toward London. I’m riding with seventeen members of the Cardiff Socialist Party, of which Saunders is branch secretary for the Cardiff West branch; they’re going to participate in a march that’s part of the protests against the G-20 meeting.

Before we boarded the minibus Saunders made a speech outlining the reasons for the march. He said they were “fighting for jobs for young people, fighting for free education, fighting for our share of the wealth, which we create.” His anger is directed at the government’s response to the economic downturn: “Now that the recession is underway, they’ve been trying to shoulder more of the burden onto the people, and onto the young people…they’re expecting us to pay for it.” He compared the protest to the Jarrow March and to the miners’ strikes which were hugely influential in the history of the British labour movement. The people assembled, though, aren’t miners or industrial workers — they’re university students or recent graduates, and the march they’re going to participate in is the Youth Fight For Jobs.

The Socialist Party was formerly part of the Labour Party, which has ruled the United Kingdom since 1997 and remains a member of the Socialist International. On the bus, Saunders and some of his cohorts — they occasionally, especially the older members, address each other as “comrade” — explains their view on how the split with Labour came about. As the Third Way became the dominant voice in the Labour Party, culminating with the replacement of Neil Kinnock with Tony Blair as party leader, the Socialist cadre became increasingly disaffected. “There used to be democratic structures, political meetings” within the party, they say. The branch meetings still exist but “now, they passed a resolution calling for renationalisation of the railways, and they [the party leadership] just ignored it.” They claim that the disaffection with New Labour has caused the party to lose “half its membership” and that people are seeking alternatives. Since the economic crisis began, Cardiff West’s membership has doubled, to 25 members, and the RMT has organized itself as a political movement running candidates in the 2009 EU Parliament election. The right-wing British National Party or BNP is making gains as well, though.

Talk on the bus is mostly political and the news of yesterday’s violence at the G-20 demonstrations, where a bank was stormed by protesters and 87 were arrested, is thick in the air. One member comments on the invasion of a RBS building in which phone lines were cut and furniture was destroyed: “It’s not very constructive but it does make you smile.” Another, reading about developments at the conference which have set France and Germany opposing the UK and the United States, says sardonically, “we’re going to stop all the squabbles — they’re going to unite against us. That’s what happens.” She recounts how, in her native Sweden during the Second World War, a national unity government was formed among all major parties, and Swedish communists were interned in camps, while Nazi-leaning parties were left unmolested.

In London around 11am the march assembles on Camberwell Green. About 250 people are here, from many parts of Britain; I meet marchers from Newcastle, Manchester, Leicester, and especially organized-labor stronghold Sheffield. The sky is grey but the atmosphere is convivial; five members of London’s Metropolitan Police are present, and they’re all smiling. Most marchers are young, some as young as high school age, but a few are older; some teachers, including members of the Lewisham and Sheffield chapters of the National Union of Teachers, are carrying banners in support of their students.

Stewards hand out sheets of paper with the words to call-and-response chants on them. Some are youth-oriented and education-oriented, like the jaunty “Gordon Brown‘s a Tory/He wears a Tory hat/And when he saw our uni fees/He said ‘I’ll double that!'” (sung to the tune of the Lonnie Donegan song “My Old Man’s a Dustman“); but many are standbys of organized labour, including the infamous “workers of the world, unite!“. It also outlines the goals of the protest, as “demands”: “The right to a decent job for all, with a living wage of at least £8 and hour. No to cheap labour apprenticeships! for all apprenticeships to pay at least the minimum wage, with a job guaranteed at the end. No to university fees. support the campaign to defeat fees.” Another steward with a megaphone and a bright red t-shirt talks the assembled protesters through the basics of call-and-response chanting.

Finally the march gets underway, traveling through the London boroughs of Camberwell and Southwark. Along the route of the march more police follow along, escorting and guiding the march and watching it carefully, while a police van with flashing lights clears the route in front of it. On the surface the atmosphere is enthusiastic, but everyone freezes for a second as a siren is heard behind them; it turns out to be a passing ambulance.

Crossing Southwark Bridge, the march enters the City of London, the comparably small but dense area containing London’s financial and economic heart. Although one recipient of the protesters’ anger is the Bank of England, the march does not stop in the City, only passing through the streets by the London Exchange. Tourists on buses and businessmen in pinstripe suits record snippets of the march on their mobile phones as it passes them; as it goes past a branch of HSBC the employees gather at the glass store front and watch nervously. The time in the City is brief; rather than continue into the very centre of London the march turns east and, passing the Tower of London, proceeds into the poor, largely immigrant neighbourhoods of the Tower Hamlets.

The sun has come out, and the spirits of the protesters have remained high. But few people, only occasional faces at windows in the blocks of apartments, are here to see the march and it is in Wapping High Street that I hear my first complaint from the marchers. Peter, a steward, complains that the police have taken the march off its original route and onto back streets where “there’s nobody to protest to”. I ask how he feels about the possibility of violence, noting the incidents the day before, and he replies that it was “justified aggression”. “We don’t condone it but people have only got certain limitations.”

A policeman I ask is very polite but noncommittal about the change in route. “The students are getting the message out”, he says, so there’s no problem. “Everyone’s very well behaved” in his assessment and the atmosphere is “very positive”. Another protestor, a sign-carrying university student from Sheffield, half-heartedly returns the compliment: today, she says, “the police have been surprisingly unridiculous.”

The march pauses just before it enters Cable Street. Here, in 1936, was the site of the Battle of Cable Street, and the march leader, addressing the protesters through her megaphone, marks the moment. She draws a parallel between the British Union of Fascists of the 1930s and the much smaller BNP today, and as the protesters follow the East London street their chant becomes “The BNP tell racist lies/We fight back and organise!”

In Victoria Park — “The People’s Park” as it was sometimes known — the march stops for lunch. The trade unions of East London have organized and paid for a lunch of hamburgers, hot dogs, french fries and tea, and, picnic-style, the marchers enjoy their meals as organized labor veterans give brief speeches about industrial actions from a small raised platform.

During the rally I have the opportunity to speak with Neil Cafferky, a Galway-born Londoner and the London organizer of the Youth Fight For Jobs march. I ask him first about why, despite being surrounded by red banners and quotes from Karl Marx, I haven’t once heard the word “communism” used all day. He explains that, while he considers himself a Marxist and a Trotskyist, the word communism has negative connotations that would “act as a barrier” to getting people involved: the Socialist Party wants to avoid the discussion of its position on the USSR and disassociate itself from Stalinism. What the Socialists favor, he says, is “democratic planned production” with “the working class, the youths brought into the heart of decision making.”

On the subject of the police’s re-routing of the march, he says the new route is actually the synthesis of two proposals. Originally the march was to have gone from Camberwell Green to the Houses of Parliament, then across the sites of the 2012 Olympics and finally to the ExCel Centre. The police, meanwhile, wanted there to be no march at all.

The Metropolitan Police had argued that, with only 650 trained traffic officers on the force and most of those providing security at the ExCel Centre itself, there simply wasn’t the manpower available to close main streets, so a route along back streets was necessary if the march was to go ahead at all. Cafferky is sceptical of the police explanation. “It’s all very well having concern for health and safety,” he responds. “Our concern is using planning to block protest.”

He accuses the police and the government of having used legal, bureaucratic and even violent means to block protests. Talking about marches having to defend themselves, he says “if the police set out with the intention of assaulting marches then violence is unavoidable.” He says the police have been known to insert “provocateurs” into marches, which have to be isolated. He also asserts the right of marches to defend themselves when attacked, although this “must be done in a disciplined manner”.

He says he wasn’t present at yesterday’s demonstrations and so can’t comment on the accusations of violence against police. But, he says, there is often provocative behavior on both sides. Rather than reject violence outright, Cafferky argues that there needs to be “clear political understanding of the role of violence” and calls it “counter-productive”.

Demonstration overall, though, he says, is always a useful tool, although “a demonstration is always a means to an end” rather than an end in itself. He mentions other ongoing industrial actions such as the occupation of the Visteon plant in Enfield; 200 fired workers at the factory have been occupying the plant since April 1, and states the solidarity between the youth marchers and the industrial workers.

I also speak briefly with members of the International Bolshevik Tendency, a small group of left-wing activists who have brought some signs to the rally. The Bolsheviks say that, like the Socialists, they’re Trotskyists, but have differences with them on the idea of organization; the International Bolshevik Tendency believes that control of the party representing the working class should be less democratic and instead be in the hands of a team of experts in history and politics. Relations between the two groups are “chilly”, says one.

At 2:30 the march resumes. Rather than proceeding to the ExCel Centre itself, though, it makes its way to a station of London’s Docklands Light Railway; on the way, several of East London’s school-aged youths join the march, and on reaching Canning Town the group is some 300 strong. Proceeding on foot through the borough, the Youth Fight For Jobs reaches the protest site outside the G-20 meeting.

It’s impossible to legally get too close to the conference itself. Police are guarding every approach, and have formed a double cordon between the protest area and the route that motorcades take into and out of the conference venue. Most are un-armed, in the tradition of London police; only a few even carry truncheons. Closer to the building, though, a few machine gun-armed riot police are present, standing out sharply in their black uniforms against the high-visibility yellow vests of the Metropolitan Police. The G-20 conference itself, which started a few hours before the march began, is already winding down, and about a thousand protesters are present.

I see three large groups: the Youth Fight For Jobs avoids going into the center of the protest area, instead staying in their own group at the admonition of the stewards and listening to a series of guest speakers who tell them about current industrial actions and the organization of the Youth Fight’s upcoming rally at UCL. A second group carries the Ogaden National Liberation Front‘s flag and is campaigning for recognition of an autonomous homeland in eastern Ethiopia. Others protesting the Ethiopian government make up the third group; waving old Ethiopian flags, including the Lion of Judah standard of emperor Haile Selassie, they demand that foreign aid to Ethiopia be tied to democratization in that country: “No recovery without democracy”.

A set of abandoned signs tied to bollards indicate that the CND has been here, but has already gone home; they were demanding the abandonment of nuclear weapons. But apart from a handful of individuals with handmade, cardboard signs I see no groups addressing the G-20 meeting itself, other than the Youth Fight For Jobs’ slogans concerning the bailout. But when a motorcade passes, catcalls and jeers are heard.

It’s now 5pm and, after four hours of driving, five hours marching and one hour at the G-20, Cardiff’s Socialists are returning home. I board the bus with them and, navigating slowly through the snarled London traffic, we listen to BBC Radio 4. The news is reporting on the closure of the G-20 conference; while they take time out to mention that Canadian Prime Minister Stephen Harper delayed the traditional group photograph of the G-20’s world leaders because “he was on the loo“, no mention is made of today’s protests. Those listening in the bus are disappointed by the lack of coverage.

Most people on the return trip are tired. Many sleep. Others read the latest issue of The Socialist, the Socialist Party’s newspaper. Mia quietly sings “The Internationale” in Swedish.

Due to the traffic, the journey back to Cardiff will be even longer than the journey to London. Over the objections of a few of its members, the South Welsh participants in the Youth Fight For Jobs stop at a McDonald’s before returning to the M4 and home.

Viktor Schreckengost, the father of industrial design and creator of the Jazz Bowl, an iconic piece of Jazz Age art designed for Eleanor Roosevelt during his association with Cowan Pottery died yesterday. He was 101.

Schreckengost was born on June 26, 1906 in Sebring, Ohio, United States.

Schreckengost’s peers included the far more famous designers Raymond Loewy and Norman Bel Geddes.

In 2000, the Cleveland Museum of Art curated the first ever retrospective of Schreckengost’s work. Stunning in scope, the exhibition included sculpture, pottery, dinnerware, drawings, and paintings.

At least nine people have died in northern Italy after a landslide caused the derailment of a passenger train. A further 25 people were injured, according to emergency services.

The incident occurred earlier this morning near the border with Austria, in a mountainous region near Merano, a city around 300 kilometres north of Venice.

“There are nine confirmed victims, while 28 people have been injured, seven of them seriously,” reported the governor of the Bolzano-Bozen province, Luis Durnwalder, to the Reuters news service. Initially, eleven people were reported dead, due to what the governor described as a “counting error”. However, he noted that “there could still be someone buried in the mud”, so the death count is not yet final.

According to the ANSA news agency, the train had about forty passengers on board when it derailed. Sky TV, meanwhile, quoted officials as saying that three people are reported to be missing. The authorities say the landslide was due to a broken irrigation pipe, which caused rocks to fall onto the tracks below. Authorities say they are looking into why the pipe burst.

The trains front car hit two trees upon derailment, local media says, which prevented it from dropping off into a river below. The carriage, however, was hanging over the river, and firefighters had to use cables to stop it from falling any more. A crane was also dispatched the scene to help clean up debris, ANSA reported.

“The train is hanging off the rails about five meters from the river. It is now only a few trees that are holding up the train and preventing it falling into the river,” said a witness, Alex Rowbotham, to the BBC.

“[…] The landslide occurred at the very passage of the train. It hit the train,” said Thomas Widmann, a transport official for the city of Bolanzo.

The crash was the deadliest in Europe since February, when eighteen people died after two commuter trains ran into each other near Brussels, Belgium. Italy saw its worse rail crash two decades ago, when 29 people died following the derailment of a freight train carrying petroleum gas, resulting in several explosions.

Wikinews reporter Iain Macdonald has performed an interview with Dr Isabella Margara, a London-based member of the Communist Party of Greece (KKE). In the interview Margara sets out the communist response to current events in Greece as well as discussing the viability of a communist economy for the nation. She also hit back at Petros Tzomakas, a member of another Greek far-left party which criticised KKE in a previous interview.

The interview comes amid tensions in cash-strapped Greece, where the government is introducing controversial austerity measures to try to ease the nation’s debt-problem. An international rescue package has been prepared by European Union member states and the International Monetary Fund – should Greece require a bailout; protests have been held against government attempts to manage the economic situation.

Russian President Vladimir Putin heavily criticized the United States in a speech at the 43rd Munich Conference on Security Policy Saturday for what he called its “almost uncontained” use of force in the world.

Putin also criticized US plans for missile defense systems and NATO’s expansion.

Putin said that nations are witnessing an “almost uncontained hyper use of force” in international relations. The Russian President pointed out that only the UN, and not the EU or NATO, can sanction the legitimate use of force. “One state, the United States, has overstepped its national borders in every way.”

Putin stated that the “excessive use of force” showed a lack of capacity for “complex solutions”.

“This is very dangerous. Nobody feels secure anymore because nobody can hide behind international law,” he said, speaking through a translator. “This is nourishing an arms race with the desire of countries to get nuclear weapons,” he told the 250 officials, including more than 40 defense and foreign ministers.

Speaking about the US missile defense system, possibly to be deployed in Poland and the Czech Republic, he stated that Washington’s reasons for the system weren’t plausible. Even such problem states like North Korea would not be able to build any missile in a foreseeable time necessitating such a defensive measure, the President opined.

Vladimir Putin also stated his doubts about the United States’ willingness to really go ahead with disarmament. He said that Russia was strictly adhering to the agreement to destroy thousands of strategic nuclear weapons until the end of 2012. He also said, he hoped the partner was acting in an equally transparent manner and would not keep a few hundred warheads for “bad times”.

The Munich Conference on Security Policy, founded in 1962, is an international forum composed of more than 250 leading politicians, diplomats, military officials, members of the business community, academics and public figures from more than 40 countries. It has become an annual opportunity for world leaders to discuss the most pressing issues of the day.

A study published in journal Astronomy & Astrophysics last month reported astronomers from the European Southern Observatory (ESO) and elsewhere discovered a black hole in the Telescopium constellation. The study stated the black hole is about 1010 ± 195 light years (310 ± 60 parsec) away from the Solar System, meaning it is the nearest known black hole from the Earth. The nearest previously known black hole — V616 Mon — the study noted was usually estimated at more than 3000 light years away.

The black hole described in the study is located in the HR 6819 stellar system of Telescopium constellation, making it the first system visible to the naked eye to contain a black hole. HR 6819 contains two stars, and they are visible from the Southern Hemisphere. The astronomers started observing the system in 1999. Initially, they thought it was just a binary system, consisting of two stars. However, upon examination, the researchers concluded there was a third unseen object in the system. One of the two stars in the HR 6819 system is close to the black hole and orbits the black hole in just 40.333 ± 0.004 days.

This newly discovered black hole does not have an accretion disk. A black hole forms an accretion disk when a significant amount of matter orbits the black hole, as depicted in the image. Accretion disks often emit electromagnetic radiation. Since this black hole does not have an accretion disk, researchers had to rely on the gravitational effect of the black hole on the nearby star in order to discover it.

Researchers used the binary mass function to conclude the black hole had a mass of at least 4.2 M_? (Solar masses; 1 Solar mass = mass of the Sun). Its companion star, which orbits the black hole in about 40 days, is classified as a B3 III star. The outer star is classified as a Be star. Be stars rotate very quickly around their axes. Since the outer star rotates so rapidly, the star is not exactly spherical, but instead oblate, bulged at its equator, forming a gas disk around the equator.

The research suggested HR 6819 was very similar to another system LB-1. The HR 6819 system is estimated to be between 15–75 million years old (myr). The inner star has estimated mass of at least 6.3 ± 0.7 M_?. Using the mass and the speed at which the inner star rotates, the researchers concluded the black hole had an estimated mass of 5.0 ± 0.4 M_?. Researcher and co-author of the study Thomas Rivinius told Wikinews the inner star and the black hole are closer than the Sun and the Earth (1au; 150 million km; 93 million miles).

The researchers dedicated the paper to Stanislav Štefl, one of the fellow researchers who died in a car accident in 2014 in Santiago, Chile.

Wikinews caught up with Thomas Rivinius to discuss about this discovery.
