The diamond is known to be the hardest mineral in the world. Well, after being under a lot of pressure and under high temperatures, who wouldn’t be made tough? But when it comes to hardness, diamonds can’t get any harder. Scientists have discovered that the mineral in question is “metastable”.

In a series of new experiments, scientists have found that diamonds retain their crystal structure at pressures five times higher than that of Earth's core.

This contradicts predictions that diamond should transform into an even more stable structure under extremely high pressure, suggesting that diamond sticks to a form under conditions where another structure would be more stable, what is referred to as being 'metastable'.

The discovery has implications for modelling high-pressure environments such as the cores of planets rich in carbon.

A great sleep and dreams of chicken and gravy. If you’re the person who longs for these things, then you might consider getting yourself the Mocchiri Juicy Karaage (“Springy Juicy Fried Chicken”) pillow made by the Japanese brand Fellisimo. The pillows, which cost around $32 apiece, are available in three sizes.

The pillows include a pouch to hold your smartphone, and you’re encouraged to play the ASMR YouTube video of chicken sizzling and frying provided by Fellisimo…

Careful not to get hungry, though.

Have you ever wondered how the thumb, the most important finger in your hand, evolved? Scientists also wonder the same about the said finger, and they might finally have an answer to that question through this study modeling muscle in fossilized thumbs.

It’s a “thorough, robust analysis,” says Tracy Kivell, a paleoanthropologist at the University of Kent who was not involved with the work. But she and others caution that the research is too preliminary to provide a true smoking gun.

Figuring out how ancient thumbs worked isn’t easy. Fossils don’t preserve muscles, so most previous attempts to estimate ancient dexterity relied on how closely our ancient relatives’ hand bones resembled our own. Hand bones are also small and relatively rare in the fossil record. But resemblance can be deceiving: Depending on how the muscles are connected, some species with similar bone anatomy might have very different grip strengths, and vice versa.

January 28, 1986. It was the day when five NASA astronauts and two payload specialists lost their lives. It was the day that the Space Shuttle Challenger unexpectedly exploded after 73 seconds into its flight. It was a day worth learning from.

The shockwaves through NASA and its aerospace and defense partners were immense, and it took more than two years to resume flights after an external investigation, redesigns and other measures. The accident also caused a few program cancellations, such as an astronaut jetpack that flew spacewalkers on satellite rescue missions and a plan to launch space shuttles from California in addition to Florida.

NASA remembers and since then has learned from its mistakes that led to the tragedy 35 years ago.

It seems that humans are not alone when it comes to having diverse languages and dialects. Mole rat colonies have those, too. And much like how we humans sometimes identify ourselves with those who have the same dialect as ours, mole rats also do the same.

Shared dialect [in mole rats] also strengthens cohesion within a colony, a team led by MDC researcher Gary Lewin reports in Science.

[...]

Lewin worked with Dr. Alison Barker from his own team and other researchers from the MDC and the University of Pretoria in South Africa—Professor Nigel Bennett and Dr. Daniel Hart—to more closely analyze the chirps that the naked mole-rats use to greet one another. "In so doing, we established that each colony has its own dialect," reports Barker, lead author of the study published in Science. "The development of a shared dialect strengthens cohesion and a sense of belonging among the naked mole-rats of a specific colony."

Foreigners are not welcome in an established naked mole rat colony. "You might even say that these animals are extreme xenophobes," says Lewin, who has been studying naked mole rats for around 20 years at the MDC.

There are games that make players want to replay all over again because it’s just that good (for them). Besides personal preferences, games also incentivize its players to replay the game by adding benefits, new features, or new gameplay mechanics as the player starts all over again. From easing the difficulty of the game, to adding a new higher difficulty mode, to giving bonus levels or experience points, there are multiple ways to encourage players to replay their favorite games. Design Doc delves deeper into what criterias make a good new game plus. 

TOI-178 is a unique planetary system. The system is not just a group of heavenly bodies revolving around a star, no. The planets dance around their star in a rhythmic pattern, and astronomers can actually hear the beat to which the planets are dancing to. Strange, indeed!

Remember the viral Bernie meme from a few days ago? Well, a crochet doll version of the politician sitting during inauguration day sold for a whopping $20,000. Texas resident Tobey King turned the meme into a crochet doll for about seven hours of non-stop crocheting. The doll captured the exact look, including the mittens that stole the show during the inauguration.

Ever wondered what the interior of a military submarine looks like? Well, wonder no more! The Royal Netherlands Navy (RNN) has provided a drone tour inside their Walrus-class diesel electric submarine. Walrus-class submarines are one of the most effective non-nuclear powered submarines used for intelligence collection : 

The drone video shows off a number of important spaces in the sub, starting with the torpedo room. Each submarine has four 533-millimeter torpedo tubes. A typical load of ammunition includes 20 torpedoes and missiles, including American-made Mk. 48 heavyweight general purpose torpedoes and Sub-Harpoon anti-ship missiles.

In this video, the weapon storage racks are empty, and the missiles and torpedoes have been offloaded while the boat is in port, but the drone does give a closeup of the hatches leading to the torpedo tubes themselves.

Penn Holderness (previously at Neatorama) sings a song about his Attention Deficit Hyperactivity Disorder (ADHD) to the tune of "Under the Sea" from The Little Mermaid. It's the most cheerful description you'll ever hear. He has learned to channel his differences into creativity, which he refers to a "superpower." Holderness is lucky to have a supportive wife to keep him on track. -via Metafilter

The short answer is to turn them into foundations for new coral reefs! Take for example, the Platform Holly, a decommissioned oil rig. Standing 235ft (72m) above the waters of the Pacific Ocean, the abandoned oil rig is now home to colourful fish, crabs, starfish and mussels that congregate on the oil rig’s huge steel pylons. BBC has more details on how we can turn other oil rigs into new homes for creatures and coral reefs: 

But there is one way in which these old rigs can be remarkably useful: the subsurface rig provides the ideal skeleton for coral reefs. Teeming with fish and other wildlife, scientists say that offshore rigs like Platform Holly are in fact the most bountiful human-made marine habitats in the world.

The practice of transforming rigs into reefs in the United States dates back almost 40 years. In 1984, the US Congress signed the National Fishing Enhancement Act which recognised the benefits artificial reefs provided and encouraged states to draw up plans to turn defunct rigs into reefs. The five coastal states on the Gulf of Mexico – Alabama, Florida, Louisiana, Mississippi and Texas – all have rigs-to-reefs programmes and have converted more than 500 oil and gas platforms into artificial reefs.

When oil companies cease drilling in these states, they decommission their platform by sealing the oil well. Then they can either choose to remove the entire platform or convert it into a reef by removing just the upper section of the structure.

The owner of most Ikea stores recently purchased a property in the state of Georgia to protect it from development. Ingka Group worked with nonprofit organization The Conservation Fund to save the 10, 840-acre land from destruction. This is not the first property that the company has bought, as it has over 613,000 acres of forest land across Europe and the U.S.: 

Ikea’s mission has long included looking out for the well-being of the environment, but buying land is still relatively new for the company. That investment will pay off in spades toward Ikea’s goal of becoming entirely carbon-neutral by 2030.

It’s easy to buy up carbon offsets on the internet — it’s another level of commitment entirely to buy full-on forests. And Ikea’s only getting started.

Ikea said this week that its 2020 operations used fewer fossil fuels than ever before and that it expects that trend to continue moving forward. Last year, the company sourced more than 98 percent of wood for its products from responsibly managed forests — and announced that, by 2030, at least a third of its wood will be recycled.

Ikea also made other big sustainability moves last year, like discontinuing the sale of non-rechargeable batteries, ending the print version of its catalog, and launching its own secondhand store.

What do you think about the company’s movements against deforestation?

Thanks to global warming, archaeologists were able to obtain hundreds of Viking artifacts from the ice. Well, at least the phenomenon brought something good for us, right? Archaeologists from the Secret of the Ice project discovered 68 arrows from an ancient Viking hunting ground. The Langfonne ice patch, where the arrows were found, was once part of a Viking trade route. Artnet lists the top six discoveries from ice patches in the recent years, and how the Vikings used them. Check the full list here.
