Lockheed Martin has officially begun production of its experimental jet capable of flying at supersonic speeds without creating loud supersonic booms

Sun’s long-lost sibling — A nearby star, HD 186302, was almost certainly born from the same cloud of gas the Sun was 4.6 billion years ago. Astronomers have found it has an almost identical chemical composition as the Sun, is on a similar orbit around the Milky Way, and has the same age (within uncertainties). Interestingly, it’s only 184 light years away, implying statistically many more such stars are waiting to be discovered.
~ Hear that, Elon Musk? Maybe it’s time for you to leave us. 

The Earth is sucking up water — The Earth around the Mariana Trench, which contains the deepest point on the planet, could be slurping up at least four times more water than previously estimated, according to new research.
~ This fact does my head in. 

‘Experimental’ Lockheed jet enters production — Lockheed Martin’s X-59 Quiet Supersonic Technology aircraft (main picture, above) is officially in “the manufacturing phase,” bringing the company “one step closer to enabling supersonic travel for passengers around the world.” The experimental jet was awarded a contract from NASA earlier this year as it is capable of flying at supersonic speeds without creating loud supersonic booms. Currently, commercial supersonic aircraft are banned from flying over land because of the noise and potential damage the booms may cause.
~ So, it creates quiet supersonic booms? Looks like there’s room for two passengers – and they’ll have to lie down. 

Solid plane flies without moving parts — The first ever ‘solid state’ plane, with no moving parts in its propulsion system, has successfully flown for a distance of 60 metres, proving that heavier-than-air flight is possible without jets or propellers. The flight represents a breakthrough in ‘ionic wind’ technology, which uses a powerful electric field to generate charged nitrogen ions, which are then expelled from the back of the aircraft, generating thrust. Steven Barrett, an aeronautics professor at MIT and the lead author of the study published in the journal Nature, said the inspiration for the project came straight from the science fiction of his childhood.
~ Shh! Don’t tell them about paper darts, kites, gliders and balloons! (And they say Americans don’t understand iony!)

First full-body human scans — EXPLORER, the world’s first medical imaging scanner that can capture a 3-D picture of the whole human body at once, has produced its first scans. The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined positron emission tomography (PET) and X-ray computed tomography (CT) scanner that can image the entire body at the same time.
Because the machine captures radiation far more efficiently than other scanners, EXPLORER can produce an image in as little as one second and, over time, produce movies that can track specially tagged drugs as they move around the entire body.
~ I hate it when my drugs get tagged. When is the Council going to do something!?

High-fat, low-carb Keto diet gets critiqued by scientists — Diet fads often make the lofty claim that adjusting food habits one way or another will produce the dieter’s desired results. More specifically: eat this, not that, and watch the kilos fall off. But diets are hard to sustain, and diet debunking is constantly calling into question what and how much we should be eating.
In a review published this week in Science, scientists from diverse backgrounds and research focuses came together to address whether a high-fat, low-carbohydrate diet or vice versa was the better option for maintaining good health, as well as whether the specific kinds of fat and carbs mattered.
~ All I know is that too much of any one thing will never be good for you, and the darker the fruit or vegetable, the better it is for you. 

Entirely new and bizarre microbes — Canadian scientists have identified microscopic creatures that are so unlike anything seen before, they had to create an entirely new branch on the evolutionary tree of life to slot them in. A new paper published in Nature offers the first genetic analysis of hemimastigotes: a rare and poorly understood group of single-celled microorganisms. Biologists have known about these wee beasties for well over a century, but only now can hemimastigotes be officially slotted into the evolutionary tree of life, a process more formally known as phylogeny. And by doing so, scientists have stumbled upon a completely new branch on the tree of life – one dating back billions of years.
~ They were collected from soil found along the Bluff Wilderness Trail in Nova Scotia, Canada.

Dutch art sleuth finds missing Byzantine mosaic — Art sleuth Arthur Brand, famous in the art world for tracking down works of art thought to be lost or destroyed has delivered one of his greatest finds yet: a 1600-year-old Byzantine-era mosaic of Saint Marks stolen from a Cyprus church after the Turkish invasion in 1974. It was in the possession of a British family, who bought the mosaic in good faith more than four decades ago. They were horrified when they found out that it was, in fact, a priceless art treasure, looted from the Kanakaria Church after the Turkish invasion, and they agreed to its return.
~ Nice job, Art!
