Day two down in London started off dismally. I am not sure how many other people feel this way, but some days I feel that all of my photography is not worthy of showcasing and that I may as well give it up. I have no idea why I get like this sometimes, but it becomes a vicious circle as when I feel uninspired, uninterested in photography, I cannot take a good image to save my life. So the feeling of uselessness gets compounded. At times like this, I crave inspiration. I crave something to come along to help me turn the corner and begin once more to believe in art. Today, it came in the form of one of the most beautiful sunrises I have ever seen.
London is rarely a clear city, with the smog dominating the sky and turning everything a mottled grey. That was exactly how it started out when I left my hotel at 6am. It was drizzling and the sky was featureless and bland. My feet were hurting and my well of creativity was dry. I stumbled forwards along the cobbled streets towards Tower Bridge with a feeling of emptiness. But all of a sudden, as I was just approaching the bridge, the sun erupted from over the top of the Docklands and the sky above me began to turn a salmon colour. All of a sudden my spirits were lifted and I decided on the shot I wanted to take. I knew this colour in the sky would not last forever and the shot I wanted to take would take a good few minutes. I wanted a panorama of the entire city taken right in the centre of tower bridge. The Shard and the city skyline would act as bookends for the scene and this would be balanced out by London Bridge in the distance. There would be a symmetry to the image and a lot of detail, 50mp simply wasn't going to cut it. So, instead of settling for a single 16mm shot of the city, I decided on a gigantic 400mp image, spanning the entire city. 8 individual shots, stitched together to make a single piece. This would take a while, as I would shoot it with both a polariser and Pro Glass filter on, slowing my shutter down by 4-stops. I had to get into position.
By the time the images were taken, the sky was turning more orange. So I decided to walk back towards the city along the South Bank. From there, I took photographs as the sky turned from red to orange, to yellow and then to a soft purple. Using my 6-stop ND filter, which mixes colour in an image like pigment on a paint palette, some of the colours I managed to capture are incredible. Each image looks like it must have been taken on a different day, such is the difference in colour. Yet the images were taken only minutes apart. I am very happy with the results, and my spirits are lifted once more. Tomorrow, it is the turn of Westminster and the London Eye.

Contaminated drinking water has led to the country having one of the highest rates of stunting for under-fives, causing lasting physical and cognitive damage
“Do you think giving my daughter this to drink makes me happy?” asks Perline as she holds out a cup of putrid brown water for Felasoa*, eight, one of her four children. “I know this water makes us all sick. But if a human being doesn't drink, we die. So we have no choice.”
The dirty water was collected from one of the small streams that run by the paddy fields near Bekalalao village in Madagascar. The streams irrigate the fields and provide drinking and bathing water for humans and animals.

Bespoke typefaces have become all the rage in Silicon Valley. Google has its Roboto font family that's become a cornerstone of the identity of many of their Material Design applications. Apple has its custom-made San Francisco, which recently became the default typeface across the entire Apple family of devices. And while Microsoft can't take credit for developing Segoe, the company has made the font its own, using it as a core part of the Microsoft, Windows, and Office branding.

Sunset over London
Conservationists and law enforcement have struggled to catch the Walter Whites behind wildlife trafficking. But could some plastic eggs and GPS trackers change the game?
Sometimes life really does imitate art. In the fourth season of the hit TV show, Breaking Bad, police put GPS devices on barrels of methylamine to try and track the show's protagonists to their meth lab. Inspired by the episode, Kim Williams-Guillen, a conservationist with Paso Pacifico, decided to take the concept one step further: what if you could catch wildlife poachers by slipping GPS devices into convincingly faked wildlife parts? In this case: Hollywood-inspired, high-tech sea turtle eggs; fake eggs so convincingly crafted that poachers would have a hard time distinguishing them from the real thing.
“Every year millions of sea turtle eggs are taken by poachers for sale on the black market. Paso Pacifico's solution has the potential to reveal the trade routes and destination markets for trafficked sea turtle eggs,” the U.S. Agency for International Development (USAID) said.

Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight. But such batteries have some pretty serious drawbacks: They waste much of the injected energy as heat and degrade relatively quickly. They also require expensive extra components to pump oxygen gas in and out, in an open-cell configuration that is very different from conventional sealed batteries. In a new concept for battery cathodes, nanometer-scale particles made of lithium and oxygen compounds (depicted in red and white) are embedded in a sponge-like lattice (yellow) of cobalt oxide, which keeps them stable. Researchers propose that this material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight.

A freshwater spider (Dolomedes) runs along the water's surface, leaving vortices behind its four pairs of stroking legs. In this National Science Foundation-supported project, dye studies were performed in order to determine what the propulsion mechanism is of the water strider (Gerris remigis), a common water-walking insect, approximately 1 centimeter long that resides on the surface of ponds, rivers and the open ocean.
