What is photography for? Can it change our minds? An exhibition just opened at Paris’s Palais de Tokyo, of the 18 photographers short listed for the first Prix Pictet, poses these questions loud and clear.

The Pictet prize, established this year by Pictet & Cie, one of Switzerland’s largest private banks, and co-sponsored by the Financial Times, is the only international photography prize that concerns itself directly with sustainable development and environmental issues. In that sense it isn’t quite a conventional art prize but an award – of 100,000 Swiss francs (SFr) – to be given annually to the artist who best uses the power of the camera to communicate a vital dispatch on one of the most serious issues facing us all.

Wealthy nations are reneging on commitments to help feed the world's hungry and may cite the banking crisis as a reason why they cannot do more, former U.N. Secretary-General Kofi Annan told an international conference on combating starvation. Annan's address emphasized that 10,000 children in the Third World would die from malnutrition on World Food Day alone - and this should be viewed as great a tragedy as the collapse of a bank. "The financial crisis deserves urgent attention and focus. But so does the question of hunger. Millions (this year) are liable to die. Is that any less urgent?" Annan told journalists at the Fighting Hunger conference attended by 200 foreign-aid experts from Europe, Africa and the United States.

A sweeping prominence, a huge cloud of relatively cool dense plasma is seen suspended in the Sun's hot, thin corona. At times, prominences can erupt, escaping the Sun's atmosphere. Emission in this spectral line shows the upper chromosphere at a temperature of about 60,000 degrees K (over 100,000 degrees F). Every feature in the image traces magnetic field structure. The hottest areas appear almost white, while the darker red areas indicate cooler temperatures.

The Sun is now in the quietest phase of its 11-year activity cycle, the solar minimum - in fact, it has been unusually quiet this year - with over 200 days so far with no observed sunspots. The solar wind has also dropped to its lowest levels in 50 years. Scientists are unsure of the significance of this unusual calm, but are continually monitoring our closest star with an array of telescopes and satellites. Seen here are some recent images of the Sun in more active times.

A transit of the Moon across the face of the Sun on February 25, 2007 - but not seen from Earth. This sight was visible only from the STEREO-B spacecraft in its orbit about the sun, trailing behind the Earth. NASA's STEREO mission consists of two spacecraft launched in October, 2006 to study solar storms. STEREO-B is currently about 1 million miles from the Earth, 4.4 times farther away from the Moon than we are on Earth. As the result, the Moon appears 4.4 times smaller than what we are used to.

Over Earth and Ocean, with gentle motion,
This pilot is guiding me,
Lured by the love of the genii that move
In the depths of the purple sea;
Over the rills, and the crags, and the hills,
Over the lakes and the plains,
Wherever he dream, under mountain or stream,
The Spirit he loves remains;
And I all the while bask in Heaven's blue smile,
Whilst he is dissolving in rains.

- Percy Bysshe Shelley

The work of the legendary portraitist is celebrated at a centenary exhibit at Boston's Museum of Fine Arts. Among the portraits -

Audrey Hepburn, 1956
"The French novelist Colette picked her out of a ballet lineup to play Gigi on stage, and her career was launched. When I photographed her in Hollywood and commented on her quality of sophisticated vulnerability, she told me of her harrowing experiences during the Second World War. Years later, in the Kremlin, Chairman Brezhnev agreed to sit for me only if I made him as beautiful as Audrey Hepburn."

Ice sculptures constructed from the spare core samples by the scientists working on the North Greenland Eemian Ice Drilling project.

The ice samples, which the researchers analyze for clues to the temperature and concentration of greenhouse gases of the ancient atmosphere, are collected using this drill.

The visiting group of scientists, journalists and Danish environmental officials land at NEEM, the North Greenland Eemian Ice Drilling project. NEEM had arranged for the visitors to examine their research, which focuses on the climatic conditions which shaped the warm geologic period before the earth's last Ice Age, an important clue in understanding global warming. The camp is located approximately 600 miles north of the Arctic Circle.  read more »

The new Moon drew its shadow across Earth's Eastern Hemisphere earlier today, totally eclipsing the Sun along a track that crossed the Arctic, Siberia, and interior China. Thousands of eclipse chasers had stationed themselves along the path in anticipation. The Moon's shadow arced over the Earth as the lunar body passed directly between our planet and its star. In all, the path of darkness covered about 10,200km (6,300 miles). Russia saw the longest full eclipse, for two minutes, 27 seconds, at 1021 GMT - but the UK and most of Europe experienced just a partial eclipse.

"Totality" began at sunrise at 0921 GMT in Queen Maud Gulf off Victoria Island in the territory of Nunavut, Canada. The instant of greatest eclipse occurred at 1021 GMT close to the Russian city of Nadym, before totality came to an end at 1121 GMT near the Chinese city of Xi'an, in Shaanxi province.

Tourists and amateur and professional astronomers flocked to towns in the best viewing locations along the path of totality. In Novosibirsk, Siberia's cultural and scientific capital, more than 5,000 foreign tourists were expected to show up in the city. China experienced the eclipse just a week before the opening ceremony of Beijing's Olympic Games. Chinese TV was due to broadcast the eclipse live, with crowds of people gathered along the Silk Road, a fabled trading route through the country's western deserts. Eclipses were once viewed as unlucky events in China, but the country's media had rebranded the event as "the Olympic eclipse", reports said, hoping for good fortune ahead of the sporting jamboree.

The eclipse allowed astronomers a glimpse of the Sun's corona - its outer atmosphere of super-heated gases. The area is usually impossible to see because of the bright light of the Sun, but is visible during a total eclipse as the Sun's light is obscured. Total solar eclipses usually take place about once every 18 months, and always at new Moon - when the lunar body sits directly between the Sun and the Earth. However, they do not happen every new Moon. The lunar orbit is slightly tilted to that of our planet and therefore the Moon's shadow often misses the Earth.

The world's next total eclipse of the Sun comes less than a year from now, on July 22, 2009. It will begin at sunrise in India, cross parts of Nepal, Bangladesh, Bhutan, Burma, and thickly inhabited areas of China, and will end at sunset over the South Pacific. The next total solar eclipse for North America comes on August 21, 2017. The path of totality will sweep from Oregon to South Carolina.

The Moon's shadow has two parts: an umbra and a penumbra. The umbra is the "inner" part of the Moon's shadow, and people inside this zone will witness the full glory of the eclipse. The penumbra is the Moon's faint "outer" shadow. It will only give surface viewers a partial eclipse.

In London, where the Moon's disc took its biggest bite out of the Sun at 1016 BST (0916 GMT), a maximum of 12% of the star was blotted out. Conditions were better further north. In Lerwick in the Shetland Isles, the Moon obscured as much as 36% of the Sun.

Astronomical groups reminded the public that viewing the Sun without protective equipment - even in partial eclipse phases - could result in a retinal burn and permanent eye damage. Viewing the Sun's harsh light should only be done through proper solar telescopes or glasses, or through a pinhole projection system.

The announcement by NASA of the discovery of water ice on Mars by its Phoenix Lander probe made big news everywhere. The discovery involved the observation of water ice sublimating into the air - that is, the water went from solid to vapor state without reaching the liquid stage. The Martian atmosphere has perfect conditions for sublimation - extremely thin, dry and cold. How cold? Well, you can check the Live Martian Weather Report, with data from a station on board the Phoenix Lander.

What more do we know about Mars' atmosphere? It's hundreds of times thinner than Earth's atmosphere and is made of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen, water, and methane. We also know, from observations that it can support dust storms, dust devils, clouds and gusty winds. With an amazing number of six current live probes exploring Mars (two rovers, a lander, and three orbiters), there are many thousands of images available. Only a few, however show atmospheric phenomena. Presented here are some of the best images of Martian atmosphere (and beyond) in action.

The next generation iPhone will be released in 22 countries on July 11 - and is cheaper and faster than its predecessor. Apple boss Steve Jobs unveiled the new iPhone 3G at the company's Worldwide Developers Conference in San Francisco on Tuesday morning.
"Just one year after launching the iPhone, we're launching the new iPhone 3G that is twice as fast at half the price," he told the conference. The new version will be available through Vodafone in New Zealand, and will roll out in 22 countries on July 11. By the end of 2008 it will be on the market in 70 countries.

Jobs said that the new, thinner iPhone would be "more affordable" for consumers, at US$199 for an 8-gigabyte model, and $299 for a 16GB version. The original, which has now sold out, launched last June at $599 and was reduced to $399. There will be a choice of black or white for the flagship version, although the entry-level 8GB will only be available in black. As expected, the new iPhone will be 3G network capable, meaning higher speed web browsing than the current model. This will make it more competitive in the smartphone market against Research In Motion's BlackBerry and Nokia's N95. Currently Apple enjoys a 20 percent share of the US smartphone market, but only 5 per cent in the rest of the world. The iPhone's slow internet browsing speed has been widely criticised - but it was originally designed with a firm focus on the American market, and 'official carrier' AT&T did not, at that time, have a network that was up to speed with 3G. Other countries, like New Zealand, have been 3G capable for some time.

The new iPhone also comes with GPS satellite navigation built in for location-based services, whereas the previous model used a combination of Wi-Fi and cell tower responses to determine a users' location. In true iTunes Store style, the new App Store - available in 62 countries at launch - will let users download applications directly to their phones. Most will need to be purchased, but Apple promises some free content. iPhone 3G addresses numerous issues with the original, adding a flush-mounted headphone jack and, importantly, increasing battery life. Apple now claims a standby time of 300 hours, with 10 hours talktime on a 2G network or 5 on a 3G network. Enthusiastic web browsers will get five to six hours of surfing, and the battery will play audio for up to 24 hours. iPhone 3G is compatible with quad-band GSM and tri-band HSDPA for voice and data connectivity around the world. It supports Wi-Fi, 3G and EDGE networks and automatically switches between them to ensure the fastest possible download speeds. It runs simultaneous data and voice connections so it's possible to check email or look up directions while on a call. Push email has now been added with MobileMe, a new web service that pushes email, contacts and calendars from an online 'cloud' to apps on iPhone, iPod Touch, Macs and PCs. Essentially, this means everything is updated without the need to continuously check email or update schedules.

It will cost $140 for individuals with 20GB of storage, or NZ$199 for a 'Family Pack' which has one master account with 20GB and four family member accounds with 5GB each. Free 60 trials will be available online, and current .Mac account holders will be automatically upgraded to the new service. For business, in an intelligent which makes the iPhone more corporate-friendly, it is now compatible with Microsoft Exchange ActiveSync, as well as remote wipe and Cisco IPsec VPN for encrypted access to networks.

A father leans out of a smoke-choked second-floor window. Just released from his grasp, his infant son hurtles backward through the air, pudgy arms flung wide. On the sidewalk below, a throng of men stare up at the baby. One holds his arms up, fingers splayed, ready to make the catch.

The dramatic moment, captured in a black-and-white photo taken by an amateur, has been retold countless times to William Sheridan Jr. since that morning 30 years ago yesterday, when his father, William Sr., dropped him into the arms of neighbor Tom Connally. Just moments before that, his father had dropped his twin sister, Nichole, who was snagged by another neighbor, Jimmy Madden. Minutes later, firefighters used a ladder to save his father and mother, Kathy Sheridan, from the raging blaze that tore through their home on East 2d Street in South Boston on May 28, 1978.

"I just remember my husband saying: 'Get up! Get up! Get up!" said Kathy Sheridan, who was 24 at the time. "And as soon as I opened my eyes, the whole apartment was full of smoke." Her husband, who was 25, grabbed the twins, but thick, black smoke blocked the stairway to the street. He broke open a window, and the couple saw neighbors on the street below, screaming, "Throw the babies!" "I just couldn't do it," Kathy Sheridan said. "All I could see was concrete." Her husband took the infants, leaned out, and dropped them. "It was just one of those crazy things," he said yesterday. "And for the most part I don't think about it."

The photo was taken by David G. Mugar, who was then a new owner of Boston's Channel 7 with a hobby of amateur news photography. He was parked in Dorchester when he heard the fire call on a scanner in his car, raced over, captured the shot, and later gave the $5,000 in proceeds from his photos to the Sheridans, whose belongings were destroyed in the fire. The photo won Mugar a number of awards, including second place in a World Press Photo Awards competition in Holland.
