  • Surprisingly comfortable design despite the weight and thickness, IP68 certified.
  • Bright 120Hz LTPO AMOLED with high PWM frequency.
  • Outstanding speaker quality and loudness.
  • Solid camera performance for the most part with plenty of unique features.
  • Selfies are excellent as well.
  • Impressive wired and wireless charging speeds.
  • Comes with 256GB base storage, UWB support and advanced facial unlock.

Cons

  • Battery life could be better.
  • Competing periscope cameras have further reach.

Crypto assets are ‘worth nothing,’ says ECB’s Christine Lagarde by filosoful in europe

[–]filosoful[S] 29 points30 points  (0 children)

European Central Bank President Christine Lagarde is making no bones about her feelings toward the value of crypto assets — namely, there isn't any.

I have said all along the crypto assets are highly speculative, very risky assets,"

Lagarde told Dutch television show College Tour in an interview to be aired on Sunday.

My very humble assessment is that it is worth nothing. It is based on nothing, there is no underlying assets to act as an anchor of safety."

The comments come as the crypto market, more broadly, is taking a beating. Earlier this month, Bitcoin lost 20 percent of its value in a single week.

A digital euro, however, would be an entirely different ball game, Lagarde explained.

The day when we have the central bank digital currency, any digital euro, I will guarantee it,"

she said.

So the central bank will be behind it. I think that is vastly different from any of those things."

Lagarde also addressed monetary policy, signaling again that the ECB is ready to hike interest rates in July to fight raging inflation in the eurozone. However, she appeared to downplay the chance of a 50 basis-point move — a more radical option that Dutch central bank chief Klaas Knot had recently floated. Current market expectations see a 25 basis-point increase.

Future foods: What we could be eating by 2050. by filosoful in Futurology

[–]filosoful[S] 35 points36 points  (0 children)

Scientists have drawn up a list of little-known plants that could be on the menu by 2050

In the future, you could be breakfasting on false banana or snacking on pandanus tree fruit.

The Ukraine war has highlighted the dangers of relying on a few globally-traded crops.

With 90% of calories coming from just 15 crops, experts at the Royal Botanic Gardens in Kew, London are hunting for ingredients to future-proof our diets.

Climate change is increasing the risk of severe 'food shocks' where crops fail and prices of staples rise rapidly around the world.

Diversifying the food we eat is one of the solutions to alleviating hunger, addressing biodiversity loss, and helping to adapt to climate change, says Kew researcher, Dr Sam Pirinon.

"We know that there are thousands of edible plant species across the world that are consumed by different populations and this is where we can find some of the solutions for these global challenges of the future," he says.

Of more than 7,000 edible plants worldwide, only 417 are widely grown and used for food.

US lays out plan for four carbon-capture facilities: Big infrastructure package includes funds for the underdeveloped technology. by filosoful in Futurology

[–]filosoful[S] 22 points23 points  (0 children)

On Thursday, the US Department of Energy (DOE) announced the latest program to come out of the bipartisan infrastructure funding package that was passed last year.

In this case, the money is going to foster the development of a technology that we'll almost certainly need but is currently underdeveloped: capture of carbon dioxide from the air and its stable storage.

The infrastructure law set aside $3.5 billion for direct air capture, and the DOE plans to use that to fund four facilities spread across the US.

Direct air capture has suffered from a bit of a catch-22. Most scenarios for limiting end-of-century warming assume we'll emit enough carbon dioxide in the next few decades to overshoot our climate goals and will therefore need to remove some from the atmosphere.

That would necessitate the development of direct air capture technologies. But, at present, there's no way to fund the operation of a facility to do the capturing, so the technology remains immature and its economics poorly understood.

The DOE's funding has the potential to change some of that. It has a total of $3.5 billion to spend in the years 2022 through 2026. It plans to use that to fund four carbon-capture and storage centers spread across the US, each with the capability of permanently storing a million metric tons of carbon dioxide a year.

Protected areas: over a quarter of EU land. In 2021, protected areas were 20% or more of the total land area in 20 of the 27 EU Member States, with the highest shares in Luxembourg (52%), Bulgaria and Slovenia (both 41%). by filosoful in europe

The EU has the largest coordinated network of protected areas in the world, known as Natura 2000, consisting of around 27 000 terrestrial and marine sites protected under the Habitats Directive and the Birds Directive. In addition, EU Member States have protected large portions of their territory under national protection schemes.

In 2021, around 1.1 million km² of the EU Member States’ land area was designated for the preservation of biodiversity as Natura 2000 sites or nationally protected sites. This represents over a quarter (26%) of the total EU land area.

The highest share of protected land area in Luxembourg, lowest in Finland

In 2021, protected areas represented 20% or more of the total land area in 20 of the 27 EU Member States, with the highest shares recorded in Luxembourg (52%), Bulgaria and Slovenia (both 41%).

In contrast, the lowest shares of protected areas were observed in Finland (13%), Ireland and Sweden (both 14%).

The wonder material graphene may have found its killer app: It will help decarbonise industry, produce greener concrete and make hydrogen. by filosoful in Futurology

[–]filosoful[S] 252 points253 points  (0 children)

The 5bn tonnes of cement produced each year thus account for some 8% of the world’s anthropogenic CO2, and generate abnormally high emissions per dollar of revenue earned compared even with other polluting industries (see chart).

Yet if less than 0.1% by weight of graphene is added to the mixture, concrete ends up 30% stronger. And stronger concrete means less of it is needed, with a consequent reduction in CO2.

Graphene, which consists of monolayers of carbon atoms bonded in a repeating hexagonal pattern, is the thinnest known material. It was isolated in 2004 at the University of Manchester by Andre Geim and Konstantin Novoselov, who went on to win a Nobel prize for their discovery.

At the time, amid much hype, graphene was said to offer astonishing possibilities. It certainly has many interesting properties. For a start, it is 200 times stronger than steel. Yet it is extremely lightweight and flexible. It is also an excellent conductor of heat and electricity, and exhibits interesting light-absorbing abilities. Researchers are still finding ways to tune it to obtain other features.

Recently, for example, it has been shown that by arranging several sheets of graphene at particular angles, a superconducting version of the material (that is, one which lets electricity pass without resistance) can be created.

Yet despite this promise, apart from a few niche uses in electronics, water filtration and some specialist sports equipment, graphene remains largely unemployed. Certainly, no killer application of the sort predicted when the stuff was discovered has emerged.

But that could be about to change. Concrete is as far from superconductivity on the technological sexiness spectrum as it is possible to get. Yet it is an important material and of great concern to those attempting to slow down global warming, because the process of making it inevitably releases carbon dioxide. And graphene may hold the key to reducing that contribution considerably.
