Cerebral malaria may have passed from gorillas to us

Humans may have originally caught malaria from gorillas, scientists say. Until now, it was thought that the human malaria parasite split off from a chimpanzee parasite when humans and chimpanzees last had a common ancestor.But researchers from the US, three African countries, and Europe have examined malaria parasites in great ape faeces.They found the DNA from western gorilla parasites was the most similar to human parasites.

Cerebral malaria
Malaria is caused by a parasite called Plasmodium, and is carried by mosquitoes. The most common species found in Africa, Plasmodium falciparum, causes dangerous cerebral malaria. Over 800,000 people die from malaria each year in the continent.
Until now, scientists had assumed that when the evolutionary tree of humans split off from that of chimpanzees - around five to seven million years ago - so had Plasmodium falciparum. This would have meant that humans and malaria co-evolved to live together. But new evidence suggests human malaria is much newer. Dr Beatrice Hahn of the University of Alabama at Birmingham, in the US, is part of a team that had been studying HIV and related infections in humans and great apes.

DNA analysis
To study the DNA of infections in wild apes, you cannot use blood samples. So the team collected 2,700 samples of faecal material from two species of gorilla - western and eastern - and from common chimpanzees and bonobos, also known as pygmy chimpanzees.They tried sequencing Plasmodium DNA from the faeces with techniques that use a large sample, and drew a genetic family tree to see which parasites were related. Dr Hahn said "When we did conventional sequencing, the tree didn't make any sense, because each sample contained a mixture of parasites."
They diluted the DNA so that they had just one parasite's genome represented in a single sample, and then amplified the DNA from there. This means they were able to separate the DNA from different species of the parasite much more effectively.They then found the tree made much more sense. But they also found some surprising results.The human Plasmodium was not very closely related to chimpanzee Plasmodium, as had been thought - but it was very closely related to one out of three species of gorilla Plasmodium from western gorillas in Central and West Africa.There was more genetic variety in the gorilla parasites than in human parasites, and Dr Hahn said this means the gorilla is likely to be the "reservoir" - the origin of the human parasite. "Other studies have just looked at chimps, so didn't find the gorilla parasite," said Dr Hahn. She added that some studies have looked at animals in captivity - so it is possible any parasites have "jumped" from their human keepers.

Cross-infection
The researchers, who report their findings in Nature, are now going to investigate further to see exactly how different the gorilla and human parasites are. Dr Hahn says that it is possible they are even the same species, and that cross-infection between humans and gorillas may be going on now. Members of the team Dr Martine Peeters and Dr Eric Delaporte of the University of Montpelier in France are working with hunters and loggers in Cameroon, who spend a lot of time in the forests. They will investigate whether these workers carry malaria parasites from the gorillas, which would suggest that new infections from other species can still happen.They also do not yet know how badly apes are affected by malaria. Dr Hahn said that the team would now like to find out whether apes are able to catch the malaria parasite, without getting ill or dying in the way that humans do.

Show me your dance moves, and I'll tell you if you are healthy

Scientists say they've carried out the first rigorous analysis of dance moves that make men attractive to women.

The researchers say that movements associated with good dancing may be indicative of good health and reproductive potential. "When you go out to clubs people have an intuitive understanding of what makes a good and bad dancer," said co-author Dr Nick Neave, an evolutionary psychologist at Northumbria University, UK. "What we've done for the very first time is put those things together with a biometric analysis so we can actually calculate very precisely the kinds of movements people focus on and associate them with women's ratings of male dancers."

Dr Neave asked young men who were not professional dancers, to dance in a laboratory to a very basic drum rhythm and their movements with 12 cameras.

These movements were then converted into a computer-generated cartoon - an avatar - which women rated on a scale of one to seven. He was surprised by the results. "We thought that people's arms and legs would be really important. The kind of expressive gestures the hands make, for example. But in fact this was not the case," he said.

"We found that (women paid more attention to) the core body region: the torso, the neck, the head. It was not just the speed of the movements, it was also the variability of the movement. So someone who is twisting, bending, moving, nodding."
Movements that went down terribly were twitchy and repetitive - so called "Dad dancing".

Dr Neave's aim was to establish whether young men exhibited the same courtship movement rituals in night clubs as animals do in the wild. In the case of animals, these movements give information about their health, age, their reproductive potential and their hormone status. "People go to night clubs to show off and attract the opposite sex so I think it's a valid way of doing this," Dr Neave explained. "In animals, the male has to be in good physical quality to carry out these movements. We think the same is happening in humans and certainly the guys that can put these movements together are going to be young and fit and healthy."

Dr Neave also took blood samples from the volunteers. Early indications from biochemical tests suggest that the men who were better dancers were also more healthy

Non-stick pans can affect our hormones, new research suggests

Norwegian study highlights the effects of PFC and PCB chemicals on human health.

A group of chemicals found in common household items may be having dangerous effects on our hormones, new research suggests. A study on sheep and cells grown in the laboratory by Norwegian vets found that perfluorinated compounds (PFCs) found in water resistant clothes and non-stick frying pans can affect the body's steroid hormones including oestrogen, testosterone and cortisol. These hormones are necessary for regulating a number of bodily functions in humans and animals, including our ability to reproduce.

The research also discovered similar effects caused by polychlorinated biphenyls (PCBs), a group of chemicals that have been banned since the 1970s but continue to persist in the environment.

Limit exposure

Study author Dr. Marianne Kraugerud, from the Norwegian School of Veterinary Science, said consumers could limit their exposure to both chemicals.
'To regulate uptake of PFCs, one could try to limit the use of clothes treated with water and grease repellent containing PFCs.

'It may also be wise to use cookware coated with non-stick "Teflon"-type coatings with care, especially when damaged. Alternatively, one may consider going back to the good old-fashioned cast iron frying pan,' she said.

I get by with a little help from my friends

Study finds being sociable is good for your health, while loneliness is as bad for you as smoking 15 cigarettes a day.

A life of booze, fags and slothfulness may be enough to earn your doctor's disapproval, but there is one last hope: a repeat prescription of mates and good conversation.

A circle of close friends and strong family ties can boost a person's health more than exercise, losing weight or quitting cigarettes and alcohol, psychologists say.
Sociable people seem to reap extra rewards from their relationships by feeling less stressed, taking better care of themselves and having less risky lifestyles than those who are more isolated, they claim.

Being lonely and isolated is as bad for a person's health as smoking 15 cigarettes a day or being an alcoholic. It is as harmful as not exercising and twice as bad for the health as being obese.

If this is true, imagine what a visit at your elderly relatives can do, not only for their quality of life, but also for their health... It might be worth planning an extra visit this month, if you want them to stick around as long as possible :-)

Does bathroom cleaner cause cancer??

Scientists claim the risk of breast cancer is doubled by the overuse of air fresheners and cleaning products that combat mould and mildew. Astonishing research claims that the perfect housewives with spotless bathrooms could be twice as likely to get breast cancer.

The amazing findings - which may even be linked to a bizarre combination of the two - emerged in a huge US study.

Breast cancer researchers for the American Silent Spring Institute quizzed more than 1,500 women about what kind of cleaning products they used - and how often.

Many were housewives waging a constant battle against bathroom mould and the build-up of mildew on windows - while at the same time trying to keep homes smelling fresh.
The institute's Julia Brody said: "Women who reported the highest combined cleaning product use had a doubled risk of breast cancer compared to those with the lowest reported use. "Use of air fresheners and products for mould and mildew control were associated with increased risk."

Insect repellents also boosted the chance of getting the disease - although there appeared to be little linking it to pesticides. The institute urged further urgent research.

If this is indeed right many of us women are at high risk because of external influences from our household. A way to minimise the risk is to use non-toxic cleaning products. Have a look here for our range of Green Home Cleaning Kits online.

Siberia melting away

If you live in a developed country, you're pretty well insulated from climate change. Shifts in weather patterns, heavier rainfall, gradually rising sea levels and temperature increases - at the moment western society absorbs these changes without us really noticing much difference. But for the indigenous peoples of the arctic who live on one of the front lines of climate change, such shifts in the planet's behaviour are much more obvious.

The Nenets people of the Yamal peninsula are nomadic reindeer herders who live within the Arctic circle on the northern coast of Siberia. In summer they graze their herds on the tundra of the peninsula, and in winter as the ground freezes they move south to milder parts of the Siberian steppes. They use the frozen surface of the landscape to cross the large rivers that criss-cross the peninsula. But things are changing.

The arctic is the most sensitive area of the planet to climate change. While the global average temperature has risen by around 0.8 degrees, some parts of Siberia have warmed by as much as five or six. And so the Nenets have noticed the freeze is happening later and later in the year. The reindeer herders have to wait longer and longer before they can move their animals south across frozen ground.

Here, on the frontiers of the world, the warming of Siberia is already threatening a way of life that has remained fairly constant for thousands of years. It's not only that the Nenets have to move later in the year - many of the freshwater lakes that dot the landscape are leaking away as the frozen walls of earth that contain the water melt, and collapse. And so the Nenets are also losing the fishing that provides one of their main sources of food.

Eternal ice
Siberia is a landscape that's underpinned by frozen ground called permafrost, but this ground is beginning to thaw. Off the coast, the coastline and even whole islands made of permafrost are vulnerable to an Arctic sea that is increasingly turbulent as sea ice also disappears. The sea is literally washing away the melting land. Melting permafrost is causing roads, pipelines and foundations to collapse across the country. Every year, there's an increase in the area of ground that melts in summer and the area that doesn't refreeze in winter.

This isn't just a problem in the arctic. This melt has global implications, because it's going to speed up climate change. Permafrost is like a giant frozen compost heap - full of dead plants, animals, trees and other carbon-rich organic matter, and in places it reaches 1500m deep. While it stays frozen, that carbon is locked up in the ground. But as the arctic warms and the permafrost thaws, microbes start to break down that organic matter, releasing carbon dioxide and methane into the atmosphere.

Flaming lakes
Methane is a potent greenhouse gas - probably causing, tonne for tonne, around 25 times more global warming over a hundred years than carbon dioxide. By lighting escaping methane, scientists can capture dramatic images of plumes of flame bubbling up through holes cut into Siberian lakes.

Melting permafrost is releasing additional emissions of greenhouse gases into the atmosphere, accelerating climate change. Permafrost contains massive amounts of carbon - probably about twice what's currently in the atmosphere, and about five times more than all greenhouse gases we've released by burning fossil fuels. While we don't have a really clear understanding of how much carbon might be released as the permafrost melts, it's fair to say that any extra greenhouse gases in the atmosphere from melting permafrost are bad news.

Because of the melting permafrost, what happens in the arctic doesn't stay in the arctic. And so we need strong political action from world leaders at Copenhagen. We need to control the warming that's leading the arctic to melt away. It's probably too late to stop climate change ending the Nenets' traditional way of life for good. But if we don't act now, that's going to be the case for pretty much everyone.

Mount Everest to host Nepal cabinet meeting

Nepal is to hold a cabinet meeting on Mount Everest to highlight the threat global warming poses to glaciers.

On 4 December prime minister Madhav Kumar Nepal and those politicians physically fit enough will ascend 17,192ft (5,250m) to base camp. In October the Maldives held a cabinet meeting underwater to warn of the effect of rising sea levels.

This meeting, to be held before the Copenhagen climate conference, aims to highlight Himalayan glacier melt. With ice in the region melting at a rapid rate, lakes have been formed which could flood nearby villages.

Melted ice and snow also makes mountaineering routes more hazardous. At such a high altitude health is a major concern, so a team of doctors will accompany the politicians. They will fly to Everest's only airstrip, Lukla. Doctors will make a final health assessment before a helicopter takes the cabinet to base camp, at the foot of Everest. Once there they will hold a brief outdoor meeting.

Mount Everest is the highest point on earth, with a summit 29,035 ft (8,850 m) above sea level.

Amazon summit in Brazil

Brazil is hosting a regional summit to discuss climate change and ways of tackling deforestation in the Amazon.

Delegates from eight nations who share the Amazon basin, as well as France which has an overseas department there, have been holding talks in Manaus. They are discussing Brazil's plan on slowing deforestation with the financial help from rich nations.
The meeting comes ahead of a global summit on climate change in Copenhagen, Denmark, next month. Brazilian President Luiz Inacio Lula da Silva is chairing the one-day summit. Delegates from Bolivia, Colombia, Ecuador, Guyana, Peru, Venezuela and Surinam, are attending, while French President Nicolas Sarkozy is representing French Guiana.

'Ambitious message'

Presidents Sarkozy and Lula said richer nations must increase their aid to help the poorer countries fight global warming. "The poor need to be supported without any country giving up its sovereignty," President Lula said.

The BBC's Paulo Cabral reports from Manaus that for the past few days diplomats have been negotiating a common position to be presented by the Amazon countries and France at the conference in Copenhagen. He says most of the presidents invited did not come to Manaus, though diplomats say that the ministers and ambassadors sent in their place are in position to close a deal. Mr Lula's spokesman said the Brazilian leader hoped that the talks would yield "an ambitious message on issues of great relevance to the region".

"Brazil believes it is crucial for the [Amazon] region to have a converging and co-operative participation," AFP news agency quoted the spokesman as saying. Brazil is proposing to combat deforestation in the Amazon basin with financial backing from wealthy nations. "Let no gringo [foreigner] ask us to let an Amazonian starve to death under a tree," Mr Lula said in a speech ahead of the meeting. "We want to preserve [the forest], but [other countries] have to pay for that preservation."

At the summit, the Brazilian government was expected to present its efforts to reduce destruction in the Amazon as a key part of its strategy to combat climate change. Earlier this month, Brazil's government said the rate of deforestation in the Amazon had dropped by 45% - and was the lowest on record since monitoring began 21 years ago. It said that just over 7,000 sq km (2,700 square miles) had been destroyed between July 2008 and August 2009. Brazil is seeking an 80% reduction in the deforestation rate by 2020.

The environmental group Greenpeace has welcomed the latest drop but says there is still too much destruction in the rainforest. Earlier this month, Brazil said it aimed to cut its carbon emissions by at least 36% below 1990 levels by 2020.

Obama to vow greenhouse emissions cuts in Denmark

Putting his prestige on the line, President Barack Obama will personally commit the U.S. to a goal of substantially cutting greenhouse gases at next month's Copenhagen climate summit. He will insist America is ready to tackle global warming despite resistance in Congress over higher costs for businesses and homeowners.

Obama will attend the start of the conference Dec. 9, a week from next Wednesday, before heading to Oslo to accept the Nobel Peace Prize. He will "put on the table" a U.S. commitment to cut emissions by 17 percent over the next decade, on the way to reducing heat-trapping pollution by 80 percent by mid-century, the White House said.

Cutting U.S. carbon dioxide emissions by one-sixth in just a decade would be likely to hike energy bills, but the administration says there would be important health trade-offs. Slashing carbon dioxide emissions could save millions of lives, mostly by reducing preventable deaths from heart and lung diseases, according to studies published this week in The Lancet British medical journal.

The White House said Obama's decision to attend the international conference in Denmark was "a sign of his continuing commitment and leadership to find a global solution to the global threat of climate change." But Obama's stopover on the conference's second day — instead of later when negotiations will be most intense and when most other national leaders will take part — disappointed some European and U.N. climate officials, as well as some environmentalists. Others said Obama's personal appeal will resonate with the delegates from more than 75 countries and help reset the U.S. image on the climate issue after eight years in which the Bush administration staunchly opposed mandatory reductions in greenhouse gases.

The president's first trip to Copenhagen — just last month — was less than fruitful. He made an unsuccessful pitch for the 2016 Summer Olympics to be held in Chicago. Obama's participation had been in doubt since it became clear that the Dec. 7-18 conference was unlikely to produce a binding agreement, The original goal of the conference was to produce a new global climate change treaty to replace the 1997 Kyoto Protocol. But in recent weeks it became clear that delegates were likely to produce at best an outline for an agreement to be considered late next year. Administration officials don't want to repeat the mistake of Kyoto, when the U.S. agreed to emission reductions but never implemented them because of strong political opposition at home. The U.S. never ratified the Kyoto agreement.

Most environmentalists hailed Obama's decision to go to Copenhagen, even if it's early in the conference. They said it will help set the tone of the talks and reverse America's image internationally on climate change. Said Michael Oppenheimer, a professor of geoscience and international affairs at Princeton University: "The U.S. has stood as the bad guy for so long that it's critically important for the U.S. president to set the tone for the meeting." But Kyle Ash, climate policy adviser for Greenpeace USA, said Obama should be even more involved, and later in the conference. "The Copenhagen climate summit is not about a photo opportunity. It's about getting a global agreement to stop climate chaos. President Obama needs to be there at the same time as all the other wold leaders," he said.

Not enough time for climate change deal?

China and the US say there isn't enough time left to agree a legally-binding agreement on climate change this year.

Charlie Kronick, senior climate advisor at Greenpeace, argues that the vast majority of countries signed up to the convention are still clamouring for an agreement with
188 countries still wanting a deal in Copenhagen....

World Food Summit Opens Amid Charges It May Be ‘Waste of Time’

World leaders start a United Nations summit on food security in Rome today that international aid agencies say may be a “waste of time” because it won’t commit donors to provide more money to end world hunger.

A draft of the final declaration for the Nov. 16 to Nov. 18 “World Summit on Food Security,” promises no new financial commitments. Governments will “reinforce all our efforts” to halve the number of hungry by 2015, it says, and rich nations should reverse the decline of aid dedicated to agriculture, which fell from 19 percent in 1980 to 3.8 percent in 2006.

Jacques Diouf, who is hosting the meeting as director general of the Food and Agriculture Organization, has urged governments to invest $44 billion a year to end chronic hunger suffered by 1.02 billion people and achieve “food security.” World hunger has continued to rise even with food prices falling from their peaks of last year, which coincided with FAO’s previous summit where donors pledged $11 billion in aid.

The lack of new funding requests prompted two aid agencies, Oxfam and ActionAid, to say on Nov. 12 the summit may be a “waste of time and money,” and that “governments are at risk of throwing away a great chance” to reduce the number of hungry. Francisco Sarmento, ActionAid’s food rights coordinator, called the declaration “just a rehash of old platitudes.”

Sixty heads of state and government plan to attend the meeting, which Pope Benedict XVI and UN Secretary-General Ban Ki-Moon will address, FAO said.

Previous Crisis

Last year’s surge in food prices sparked riots in more than a dozen countries from Ivory Coast to Haiti, where the unrest prompted the dismissal of Prime Minister Jacques Edouard Alexis.

Prices for wheat, which supplies about 20 percent of food calories consumed in the world, more than doubled between the start of 2007 and a peak in March 2008. Soaring energy prices boosted costs of fertilizer and transport while also lifting demand for grain-based alternative fuels like ethanol.

Today’s summit opens as the Rome-based UN agency predicts world cereal stocks will expand by about 4 million metric tons to 509 million tons next year, the highest level since 2002. Saudi Arabia has agreed to pay the $2.5 million cost of the gathering.

The Group of Eight nations, at a July summit in L’Aquila, Italy, approved $20 billion in aid over three years to help farmers in developing nations grow and sell food.

‘Summit Fatigue’

“My biggest concern is that we have to make sure that there is no summit fatigue,” Abdolreza Abbassian, a senior FAO economist, said in an interview. “If FAO felt there was a need for another summit, it is probably because it felt that the previous ones haven’t achieved what they were supposed to.”

Ertharin Cousin, U.S. Ambassador to the UN agencies in Rome, says the international community should use the summit as an opportunity to redefine how rich and poor countries work together to boost food production and cut poverty.

“When there is an opportunity, you don’t say ‘it is just another summit,’ you say ‘OK we are having this, how do we make it add value,’ and that was our goal,” the ambassador said in a Nov. 10 interview.

Developing countries must design their own plans and donor nations must work with them as partners, Cousin said.

“For us to suggest at the global level that we can have a patterned answer that is going to resolve all the issues on the entire continent of Africa of 54 countries is far too simplistic and very naïve,” she said.

Private Sector Role

At a FAO-organized meeting with food and agriculture companies, including Nestle, Unilever, and Bunge Ltd., in Milan on Nov. 12-13, private sector officials pledged to increase investment in farming in poor countries.

“We stand ready to invest meaningfully to help build national capacities in applied agriculture and food systems research and technology transfer in developing countries,” the companies said in a statement after the meeting.

Foreign direct investment in agriculture tripled to more than $3 billion since 2000, FAO said in report on its Web site.

Oxfam and ActionAid say the best way to reduce the number of hungry is to target resources on small farming families, who make up a third of the world’s population, FAO estimates.

Hunger Frontline

“Smallholder farmers, mostly women, are on the frontline in the fight against world poverty, hunger and climate change and we must not continue to ignore them,” said Frederic Mousseau of Oxfam.

While increased cereal production has slowed the rise in global food prices, Abbassian of FAO predicts future shortages and price hikes.

“The one certainty is that there will be a food crisis, and the reason is simple: we haven’t done much to prevent such a thing from happening,” he said. “We have talked a lot, we have committed a lot, but we haven’t really acted.”

How to Be Green: Dishwashers

Water, energy, and and often chemicals are involved in the act of washing dishes. Increasingly, so is a dishwashing machine. To stay out of hot water with your dishwashing habits, you wash and we'll dry with our dishwasher tips!

Top Tips for Greening Your Dishwashing

Check Your Habits: As usual, going green starts with a re-evaluation of what we take for granted. For example, by using fewer dishes and utensils over the course of the day, you will end up doing fewer loads in the dishwasher, saving energy, water, and detergent. Of course, you could sometimes wash your dishes by hand.

Wash Wisely: The most efficient way to use your dishwasher includes waiting until you have a full load and then running it at off-peak hours, not pre-rinsing the dishes in the sink, using an earth-friendly cleaning product, and allowing the dishes to air dry.

Shop Around: Which dishwasher you buy and use naturally plays a role in the greenness of your kitchen. To find the right machine for you, check Energy Star ratings and look into compact dishwashers.

Did You Know?

- 80% of the energy used by dishwashers goes to heating hot water
- The amount of water saved by using a fully loaded dishwasher, without pre-rinsing, in relation to the water consumed by hand-washing all of those dishes: 35%
- 400 gallons of water can be saved each month by running your dishwasher only when it is full

Punggol Waterway to have eco-friendly features

Singapore's first public housing project along the Punggol Waterway will have eco-friendly features and resort-like designs.

The 1,200-unit waterfront project will be launched in the middle of next year. The firm behind the winning design is a partnership between international architectural firm Group8asia and local design company Aedas.

They stole the crown with a distinctive sky terrace concept which creates public spaces along the waterway. More than 100 design firms from Europe and Asia took part in the Punggol Waterfront Housing Design Competition. They had to submit plans that matched the housing board's theme of "Green Living by the Waters".

HDB said the waterfront flats will be kept affordable. National Development Minister Mah Bow Tan said: "New HDB estates look like private condominiums, but don't cost as much as private condominiums.

"New innovative construction methods like pre-fabrication reduces cost and construction time. And that's one of the reasons why we are able to keep the cost of construction down."

Japan planning solar station in space!

It may sound like a sci-fi vision, but Japan's space agency is dead serious: by 2030 it wants to collect solar power in space and zap it down to Earth, using laser beams or microwaves.

The government has just picked a group of companies and a team of researchers tasked with turning the ambitious, multi-billion-dollar dream of unlimited clean energy into reality in coming decades. With few energy resources of its own and heavily reliant on oil imports, Japan has long been a leader in solar and other renewable energies and this year set ambitious greenhouse gas reduction targets.

But Japan's boldest plan to date is the Space Solar Power System (SSPS), in which arrays of photovoltaic dishes several square kilometres (square miles) in size would hover in geostationary orbit outside the Earth's atmosphere. "Since solar power is a clean and inexhaustible energy source, we believe that this system will be able to help solve the problems of energy shortage and global warming," researchers at Mitsubishi Heavy Industries, one of the project participants, wrote in a report.

"The sun's rays abound in space."

The solar cells would capture the solar energy, which is at least five times stronger in space than on Earth, and beam it down to the ground through clusters of lasers or microwaves. These would be collected by gigantic parabolic antennae, likely to be located in restricted areas at sea or on dam reservoirs, said Tadashige Takiya, a spokesman at the Japan Aerospace Exploration Agency (JAXA).

The researchers are targeting a one gigawatt system, equivalent to a medium-sized atomic power plant, that would produce electricity at eight yen (cents) per kilowatt-hour, six times cheaper than its current cost in Japan.

The challenge -- including transporting the components to space -- may appear gigantic, but Japan has been pursuing the project since 1998, with some 130 researchers studying it under JAXA's oversight. Last month Japan's Economy and Trade Ministry and the Science Ministry took another step toward making the project a reality, by selecting several Japanese high-tech giants as participants in the project. The consortium, named the Institute for Unmanned Space Experiment Free Flyer, also includes Mitsubishi Electric, NEC, Fujitsu and Sharp.

The project's roadmap outlined several steps that would need to be taken before a full-blown launch in 2030. Within several years, "a satellite designed to test the transmission by microwave should be put into low orbit with a Japanese rocket," said Tatsuhito Fujita, one of the JAXA researchers heading the project.

The next step, expected around 2020, would be to launch and test a large flexible photovoltaic structure with 10 megawatt power capacity, to be followed by a 250 megawatt prototype. This would help evaluate the project's financial viability, say officials. The final aim is to produce electricity cheap enough to compete with other alternative energy sources.

JAXA says the transmission technology would be safe but concedes it would have to convince the public, which may harbour images of laser beams shooting down from the sky, roasting birds or slicing up aircraft in mid-air. According to a 2004 study by JAXA, the words 'laser' and 'microwave' caused the most concern among the 1,000 people questioned.

2009 MTV Europe Music Awards

Music industry leaders find time for charity too.

Major celeb-packed events like the EMAs are not exactly light in the consumption department. To put it in perspective, we're talking 600 false eye lashes, more than 25 different glitters, 60 eye shadows, 300 nail polishes, 20 pots of loose powder, 200 powder puffs, and 125 different shades of lipstick to get those faces in the limelight alone, reports Reuters.

The arena, which boasts an energy-efficient design, 400 bicycle stands, and a bicycle rental service, does have vocal green efforts. And while it would be better to ban the bottled water, staff will recycle the 24,000 bottles of water artists, crew and guests were predicted to drink on site during the event.

With precision-highlighted curly locks flying in the wind machine, Beyoncé Knowles cleaned up at the 2009 MTV Europe Music Awards (EMAs), held at Berlin's O2 World arena. From four nominations, the 28-year-old Knowles took home three coveted awards: Best Female, Best Song, ("Halo") and Best Video, ("Single Ladies (Put A Ring On It)"). The Houston, Texas native gave a shout-out to hubby Jay-Z for "putting a ring on it" and a gushing thank you to friend and fellow nominee for Best Female, Shakira.

Now U2: Were the Environmentalists in the House; despite a tour said to have the same carbon footprint as a trip to Mars, U2 was probably the most environmentally active group in the house. The Irish rockers landed Best Live Act and gave a free show at the Brandenburg Gate the same night. With organic clothing company Edun, launched by Bono and his wife Ali Hewson to drive trade into Africa. Bono also wears recycled clothing, combats HIV/AIDS, and fights poverty and pushes for trade reform with One, the global activist organization he co-founded. Take that Beyoncé!

Global warming could create 150 million 'climate refugees' by 2050

Global warming will force up to 150 million "climate refugees" to move to other countries in the next 40 years, a new report from the Environmental Justice Foundation (EJF) warns.

In 2008 alone, more than 20 million people were displaced by climate-related natural disasters, including 800,000 people by cyclone Nargis in Asia, and almost 80,000 by heavy floods and rains in Brazil, the NGO said.

President Mohamed Nasheed of the Maldives, who presented testimony to the EJF, said people in his country did not want to "trade a paradise for a climate refugee camp". He warned rich countries taking part in UN climate talks this week in Barcelona "not to be stupid" in negotiating a climate treaty in Copenhagen this December. Nasheed urged governments to find ways to keep temperature rises caused by warming under 2C. "We won't be around for anything after 2C," he said. "We are just 1.5m over sea level and anything over that, any rise in sea level – anything even near that – would wipe off the Maldives. People are having to move their homes because of erosion. We've already this year had problems with two islands and we are having to move them to other islands. We have a right to live." Last month, the president held a cabinet meeting underwater to draw attention to the plight of his country.

The EJF claimed 500 million to 600 million people – nearly 10% of the world's population – are at risk from displacement by climate change. Around 26 million have already had to move, a figure that the EJF predicts could grow to 150 million by 2050. "The majority of these people are likely to be internally displaced, migrating only within a short radius from their homes. Relatively few will migrate internationally to permanently resettle in other countries," said the report's authors.

In the longer term, the report said, changes to weather patterns will lead to various problems, including desertification and sea-level rises that threaten to inundate low-lying areas and small island developing states. An expert at the Institute for Sustainable Development and International Relations in Paris recently said global warming could create "ghost states" with citizens living in "virtual states" due to land lost to rising seas.

The UN's Intergovernmental Panel on Climate Change (IPCC) predicts sea-level rise in the range of 18-59cm during the 21st century. Nearly one-third of coastal countries have more than 10% of their national land within 5 metres of sea level. Countries liable to lose all or a significant part of their land in the next 50 years, said the EJF report, include Tuvalu, Fiji, the Solomon islands, the Marshall islands, the Maldives and some of the Lesser Antilles. Many other countries, including Bangladesh, Kenya, Papua New Guinea, Somalia, Yemen, Ethiopia, Chad and Rwanda, could see large movements of people. Bangladesh has had 70 climate-related natural disasters in the past 10 years.

"Climate change impacts on homes and infrastructure, food and water and human health. It will bring about a forced migration on an unprecedented scale," said the EJF director, Steve Trent. "We must take immediate steps to reduce our impact on global climate, and we must also recognise the need to protect those already suffering along with those most at risk." He called for a new international agreement to address the scale and human cost of climate change. "The formal legal definition of refugees needs to be extended to include those affected by climate change and also internally displaced persons," he said.

With so many serious climate issues affecting us and our planet - sometimes a bit of humour can be a great tonic and raise just as much awareness in the process! Enjoy :)

5 Fun Green Ways to Manage Stress

Want to stop stressing? Then start swearing, kissing, getting dirty, cluttered and eating garlic instead!

Being "stressed" seems to be as trendy as being "on a diet." Everyone's doing it, throwing the terms around as if it's an excuse for a bad mood or short fuse. Problem is: stress has some serious side-effects that can be detrimental to your health and happiness if it isn't addressed. Of course there are lots of pills to help you ease off angst, but we prefer to do it green… naturally. No drugs, no chemicals, just good natural cures. Our favorite and the most fun by far: Kissing!

Touching, Kissing, Hugging

Touching, kissing, and hugging (or any other affectionate activities) are eco activities that stimulate the brain's release of the hormone oxytocin. If you want to take it up a notch, get a room! Recent Studies reveal that the surge of oxytocin released during orgasm can lower blood pressure, calm nerves and tame tension. In fact, according to the British Medical Journal, sex is so good for your heart that it cuts your risk of heart attack and stroke in half when performed three times a week.

Reduce Stress by Swearing it Off!

Swearing has been shown to minimize stress and increase workplace camaraderie. That's according to scientists at East Anglia Norwich University in England.

Reduce Stress by Eating Garlic

The main ingredient in garlic when digested is organosulfur allicin, which triggers your body to produce hydrogen sulfide. The combo creates an internal reaction that relaxes blood vessels and encourages blood flow. Translation: garlic is good for your heart and your head and helps manage stress.

Reduce Stress by Eating Chocolate

Balance isn't just for yoga. In fact, a little bit of chocolate can go a long way when it comes to your diet. Dark chocolate has been shown to be filled with antioxidant flavonoids (which can minimize your risk of heart disease and reduce blood pressure). Some scientists have gone so far as to claim that the sweet stuff has more flavonoids than any other food (including blueberries). According to research published in Proceedings of the National Academy of Sciences, those said flavonoids help blood vessels relax, helping calm overall stress. Word to the wise, choose the lower fat dark chocolate to milk chocolate. It has a higher count of the good stuff. And of course opt for organic chocolate.

Reduce Stress by Rubbing your Hoku

Your "hoku" is that flap of skin on your palm that connects your pointer finger to your thumb. It's also an acupressure spot related to upper body tension that, when squeezed, can minimize stress by up to 39%—that's according to scientists at Hong Kong Polytechnic University.

Climate change a challenge for Singapore

Climate change is one of the biggest challenges ahead for Singapore and Prime Minister Lee Hsien Loong said the country will bear its fair share of the global effort to reduce emissions.

This is despite the fact that Singapore's carbon emissions are a 'negligible' part of global output and it is not among nations which committed themselves and were obliged to make specific cuts in greenhouse gas emission levels.

'We don't have this obligation,' he noted on Friday in a reference to what is known as Annex I countries. 'But as a responsible member of the international community, we have to bear our fair share of the collective global effort to reduce carbon emissions.

'Therefore, provided other countries also commit to do their part in a global deal, we will reduce emissions from 'business-as-usual' levels and do what we need to do with other countries to reduce humankind's carbon-dioxide emissions.'

Speaking at the launch of the Clean and Green 2010 campaign at the HortPark on Thursday, Mr Lee said that Singapore faced serious limitations in switching to alternative energy sources or reducing its dependence on fossil fuels.
