Physicists Create New Form Of Light

For the first time, scientists have watched groups of three photons interacting and effectively producing a new form of light.

In results published in Science, researchers suggest that this new light could be used to perform highly complex, incredibly fast quantum computations.

Photons are tiny particles that normally travel solo through beams of light, never interacting with each other. But in 2013 scientists made them clump together in pairs, creating a new state of matter. This discovery shows that interactions are possible on a greater scale.

“It was an open question,” Vladan Vuletic from the Massachusetts Institute of Technology (MIT), who led the team with Mikhail Lukin from Harvard University, said in a statement. “Can you add more photons to a molecule to make bigger and bigger things?” 

The scientists cooled a cloud of rubidium atoms to an ultralow temperature to answer their question. This slowed the atoms down till they were almost still. A very faint laser beam sent just a few photons through the freezing cloud at once.

The photons came out the other side as pairs and triplets, rather than just as individuals.

Photons flit between atoms like bees among flowers

The researchers think the particles might flit from one nearby atom to another as they pass through the rubidium cloud—like bees in a field of flowers. These passing photons can could form “polaritons”—part photon, part atom hybrids. If more than one photon pass by the same atom at the same time, they might form polaritons that are linked. As they leave the atom, they could stay together as a pair, or even a triplet.

“What’s neat about this is, when photons go through the medium, anything that happens in the medium, they ‘remember’ when they get out,” said co-author Sergio Cantu from MIT.

This whole process takes about a millionth of a second.

The future of computing

This research is the latest step towards a long-fabled quantum computer, an ultra-powerful machine that could solve problems beyond the realm of traditional computers. Your desktop PC would, for example, struggle to solve the question: “If a salesman has lots of places to visit, what is the quickest route?”

“[A traditional computer] could solve this for a certain number of cities, but if I wanted to add more cities, it would get much harder, very quickly,” Vuletic previously stated in a press release.

Light, he said, is already used to transmit data very quickly over long distances via fibre optic cables. Being able to manipulate these photons could enable the distribution of data in much more powerful ways.

The team is now aiming to coerce photons in ways beyond attraction. The next stop is repulsion, where photons slam into each other and scatter.

“It’s completely novel in the sense that we don’t even know sometimes qualitatively what to expect,” Vuletic says. “With repulsion of photons, can they be such that they form a regular pattern, like a crystal of light? Or will something else happen? It’s very uncharted territory.”

Kenyans producing, selling or even using plastic bags will risk imprisonment of up to four years or fines of $40,000 (£31,000) from Monday, as the world’s toughest law aimed at reducing plastic pollution came into effect.

The east African nation joins more than 40 other countries that have banned, partly banned or taxed single use plastic bags, including China, France, Rwanda, and Italy.

Many bags drift into the ocean, strangling turtles, suffocating seabirds and filling the stomachs of dolphins and whales with waste until they die of starvation.

“If we continue like this, by 2050, we will have more plastic in the ocean than fish,” said Habib El-Habr, an expert on marine litter working with the UN environment programme in Kenya.

Plastic bags, which El-Habr says take between 500 to 1,000 years to break down, also enter the human food chain through fish and other animals. In Nairobi’s slaughterhouses, some cows destined for human consumption had 20 bags removed from their stomachs.

“This is something we didn’t get 10 years ago but now it’s almost on a daily basis,” said county vet Mbuthi Kinyanjui as he watched men in bloodied white uniforms scoop sodden plastic bags from the stomachs of cow carcasses.

Kenya’s law allows police to go after anyone even carrying a plastic bag. But Judy Wakhungu, Kenya’s environment minister, said enforcement would initially be directed at manufacturers and suppliers.

It took Kenya three attempts over 10 years to finally pass the ban, and not everyone is a fan.

Samuel Matonda, spokesman for the Kenya Association of Manufacturers, said it would cost 60,000 jobs and force 176 manufacturers to close. Kenya is a major exporter of plastic bags to the region.

“The knock-on effects will be very severe,” Matonda said. “It will even affect the women who sell vegetables in the market – how will their customers carry their shopping home?”

Big Kenyan supermarket chains like France’s Carrefour and Nakumatt have already started offering customers cloth bags as alternatives.

Being buried in the sand has a tremendous calming effect on the body. Sand baths are quite common in Mediterranean and Asian countries and are offered as a part of a spa treatment in many large cities.

In addition to relaxing the mind, sand bathing is a super effective means of removing toxins from the body. Sand is very alkaline in nature. It pulls acid out of the body while replacing minerals through osmosis. For a short while after taking a sand bath, you might feel younger and more energetic than ever before.

If you don’t live near the sea, burying yourself in the desert sand will have the same effect as a sauna, purging the body of toxins.

Tribal nomads in the desert regions of Morocco are now making a living from tourists who are looking to remove toxins and rejuvenate that body by burying them in the hot desert sands. These tribes have long run hotels in this region, but now they are using the sand surrounding their hotels as a sort of spa treatment for visitors.

Participants are buried neck deep in the hot desert sand for about 10 minutes. Their attendant will then help them out of the sand and wrap them in hot towels to avoid the shock of a suddenly cooling body. Participants are then encouraged to soak in a warm bath to help gently return the body to a more normal temperature. This sand bath therapy is said to help those who suffer from lumbago as well as skin disorders such as eczema and psoriasis, rheumatism and polyarthritis. The tribesmen will tell you that sand baths are super purifying and remove dangerous toxins from the body.

This is a video capture of the Wolaba Day Parade that happens every year in Costa Rica. Definitely enjoyed myself in the fun atmosphere of music, dancing and celebration!  This was my first time filming a festival so I decided not to get too cinematic with the editing and just cut everything simple and plain to get the sounds that were actually going on while there.
