Birds-of-paradise are known for their bright and colourful plumage, but it turns out they are even more dazzling than previously thought.

Researchers have found 37 of the 45 species show biofluorescence – in other words, patches of their plumage or other body parts absorb UV or blue light, and emit light at lower frequencies.

“At a minimum, it would make these biofluorescent areas brighter – a yellow feather may be more green-yellow, a white feather may be brighter and slightly more green-yellow,” said Dr Rene Martin from the American Museum of Natural History in New York, who was first author of the study.


Published in the journal Royal Society Open Science, Martin and colleagues reported how they studied preserved specimens of each bird-of-paradise species, held in the ornithology collection at the American Museum of Natural History.

The team placed males and females of each species under blue light in a dark room and recorded the wavelengths and intensity of light emitted. In some cases they also shone UV light on the skins.

The results revealed that males of 21 species showed biofluorescence on parts of their plumage such as their head, neck, belly and tail feathers, or on fleshy lobes known as face wattles. In addition, these species plus an additional 16 species showed – or were deemed likely to show – biofluorescence in their inner mouth and throat.

Females of 36 of these species, and most likely all 37, also showed biofluorescence. Several showed this on their chest and belly, or on feathers that form an eye stripe on the side of their head.

The team said the emitted light ranged from light or teal blue wavelengths to green and green-yellow.

“It may not have the effect of making something look different, but becoming brighter and more eye-catching,” said Martin.……

Eating from plastic takeout containers may significantly increase the chance of congestive heart failure, a new study finds, and researchers suspect they have identified why: changes to gut biome cause inflammation that damages the circulatory system.

The novel two part, peer-reviewed study from Chinese researchers adds to mounting evidence of the risks associated with eating from plastic, and builds on previous evidence linking plastic chemicals to heart disease.

The authors used a two-part approach, first looking into the frequency with which over 3,000 people in China ate from plastic takeout containers, and whether they had heart disease. They then exposed rats to plastic chemicals in water that was boiled and poured in carryout containers to extract chemicals.

“The data revealed that high-frequency exposure to plastics is significantly associated with an increased risk of congestive heart failure,” the authors wrote.


Plastic can contain any of about 20,000 chemicals, and many of them, such as BPA, phthalates and Pfas, present health risks. The chemicals are often found in food and food packaging, and are linked to a range of problems from cancer to reproductive harm.

While researchers in the new paper didn’t check which specific chemicals were leaching from the plastic, they noted the link between common plastic compounds and heart disease, and a previous link between gut biome and heart disease.……

It was when British archaeologist Dr Piers Litherland saw that the ceiling of the burial chamber was painted blue with yellow stars that he realised he had just discovered the first tomb of an Egyptian pharaoh to be found in more than a century.

Litherland had been exploring the Valley of the Kings in Egypt for more than a decade when he discovered a staircase that led to the tomb, now known to have belonged to Thutmose II, who reigned from 1493 to 1479BC.

It took months to clear flood debris from the descending corridor and during this time, he and his team assumed the tomb belonged to a royal wife.

But as soon as he saw the ceiling of the burial chamber had been decorated with scenes from the Amduat, a religious text reserved for kings, he knew he had made what has since been hailed as the most significant discovery since Tutankhamun.

He felt an “extraordinary sort of bewilderment” at that moment, he told the BBC World Service. “When I came out, my wife was waiting outside and the only thing I could do was burst into tears.”

He then set about clearing the flood debris, expecting to find the crushed remains of a burial underneath it.……

The video keeps saying basically "the map has land masses that resemble the americas" and then shows a map that has basically every continent shown exactly how they look. So i'm trying to figure out if it's the actual map. If it is then can they stop saying "resemble" but they are so accurate I think I can see my house on it!

But if it's true then it's really time to give 'ol Columbus's title of "founding the americas" the boot. We all know the Vikings were here before him but what if the Egyptians or Phoenicians were THOUSANDs of years before?!

We all "know" that the Earth was mapped with ET's help tens of thousands of years ago. Even Antartica was mapped before it was covered in ice.

If none of his contemporaries knew, then it still counts. It takes cajones to sail off the end of the world. Even if he was not the first to do it, he was the first to do it and effectively record it.

It looks like a brilliant way to avoid a traffic jam, until you imagine hundreds of people with those things. You'd get 3D traffic jams, 3D road rage, and 3D bodily injury.

Driving now, you mostly think about one dimension (speed in a straight line) and occasionally about a second dimension (turn left or right). But with those things, you'd have to constantly think about three dimensions. Are you gonna trust your Fellow Man to do that?
