This lamp runs 8 hours on just a glass of seawater

Rural areas in the Philippines with no access to electricity depend on candles, kerosene lamps or battery operated lanterns as common household light sources. But aside from being costly and inefficient, they are also dangerous to use. Now, thanks to Engr. Aisa Mijeno, a lamp that is totally safe, environmentally-friendly, and capable of emitting light on just a glass of salt water will soon brighten up these communities.

Aisa was inspired to design the SALt lamp (SALt is a contraction of Sustainable Alternative Living) after living with the natives of Kalinga's Butbut tribe for days relying only on kerosene lamps and moonlight to do evening chores.

So how does it work? As simple as it sounds, the lamp uses a solution of one glass of water mixed with two tablespoons of salt to provide 8 hours of light. It will even run off seawater. Oh, and did I mention that you can also charge your smartphone or tablet from the lamp?

The device uses the same science that forms the basis of battery-making. In a typical battery, two metal electrodes are dipped into an electrolyte solution. In this case, the electrolyte is salt water. The electrode in the SALt lamp can last up to a year, depending on how often and long it is used.

Currently in the development stage, the people behind the product aim to have the lamps mass produced later in the year. However, their main priority right now is to deliver the SALt lamps to their target communities.

Preserved tattoos of the dead

The idea of preserving tattoos after death came into existence long before NAPSA . London's Wellcome Collection has over 300 specimens of preserved human flesh bearing tattoos , collected in the late 19th century. There are many more examples of smaller collections in Paris, Poland, Portugal, Berlin, and Austria. But what fascinates me the most is this lesser-known museum at Tokyo University, the Medical Pathology Museum, which houses pieces of skin collected since 1926 by Dr. Masaichi Fukushi. "Fukushi would perform autopsies on donated cadavers and dissect off just the skin. He created a method of treatment to preserve the skin and kept them stretched in a glass frame, essentially like a leather. Later the ownership of the tattooed skin collection was passed on to Fukushi's son Katsunari. Katsunari added a further 20 tattooed skins himself and it's believed that the Medical Pathology Museum has 105 in its collection, many with full body suits." ...

Enigmatic Shapes and Psychedelic Patterns

To say that I love Sanagi 's work is an understatement. Looking at her art feels sort of therapeutic, and I find her drawings refreshingly intricate. They're trippy, psychedelic, and resemble something that you might see under a microscope. Not much is Googleable about Sanagi, but that's fine. There aren't many artists these days that still pull off the whole mysterious vibe, so I commend her for that. By the way... they're all hand-drawn with pen and ink.

Weirdly Charming

If you’re a fan of art that makes you do a double-take, you need to check out Richard Brener . Based in the UK, Richard is an internationally collected artist who works primarily with ink, fineliners, and gouache. When you first see his pieces, they actually look pretty playful. Then you realize the entire canvas is packed with thousands of tiny, ghost-like shapes he calls "champs." They’re all squeezed together like commuters on a rush-hour train, and the level of detail is honestly mind-blowing. Richard spends hundreds of hours drawing these little guys over and over. It’s obsessive, very intentional, and a little bit wild. The cool part is that the longer you stare, the more the vibe shifts. Check out more photos below:
