A metal-eating plant has been discovered in the Philippines

The new plant guzzles nickel without poisoning itself, and could be used to clean up polluted soil.

The new species, Rinorea niccolifera, somehow accumulates up to 18,000ppm of the metal in its leaves without being poisoned. That's 100 to 1,000 times higher than the level of nickel in most other plants.

The new species, which was reported on in the journal PhytoKeys, was found on the western plant of Luzan Island in the Philippines, an area known for having soils rich in heavy metals.

The ability to accumulate such a large amount of nickel is extremely rare in the plant kingdom, with only around 450 plants around the world known to have the trait, known as "hyper accumulation". Even in areas with nickel-rich soils, less than 1% of plants have the skill.

We know what you're thinking: "silly plant, metals isn't for eating!" But this ability means that not only is the plant fascinating to study, it could also help clean up soils that have been contaminated with metal.

On the other hand, it could also be used to set up a "green mining" industry, where the plant helps extract commercially valuable metals from the Earth.

Einstein’s Lost Theory Describes a Universe Without a Big Bang

Courtesy of the Archives, Calif Inst of Technology. In 1917, a year after Albert Einstein’s general theory of relativity was published—but still two years before he would become the international celebrity we know—Einstein chose to tackle the entire universe . For anyone else, this might seem an exceedingly ambitious task—but this was Einstein. Einstein began by applying his field equations of gravitation to what he considered to be the entire universe. The field equations were the mathematical essence of his general theory of relativity, which extended Newton’s theory of gravity to realms where speeds approach that of light and masses are very large. But his math was better than he wanted to believe—...

There’s a Previously Undiscovered Organ in Your Body, And It Could Explain How Cancer Spreads

Ever heard of the interstitium? No? That’s OK, you’re not alone — scientists hadn’t either. Until recently. And, hey, guess what — you’ve got one! The interstitium is your newest organ. Scientists identified it for the first time because they are better able to observe living tissues at a microscopic scale, according to a recent study published in Scientific Reports , Scientists had long believed that connective tissue surrounding our organs was a thick, compact layer. That’s what they saw when they looked at it in the lab, outside the body, at least. But in a routine endoscopy (exploration of the gastrointestinal tract), a micro camera revealed something unexpected: When observed in a living body, the connective tissue turned out to be “an open, fluid-filled space supported by a lattice made of thick collagen bundles,” pathologist and study author Neil Theise told Research Gate . This network of channels is present throughout ...
