It is basically the founding document of the World Wide Web: 9550 lines of programming code. Now the original files of the inventor Tim Berners-Lee come under the hammer.

“This changed everything” is what Sotheby’s calls the auction quite immodestly. Which, for once, shouldn’t be an exaggeration – because who would deny that the World Wide Web has actually changed almost everything. Even if its inventor Tim Berners-Lee was probably not aware of this when he presented his proposal for a system for the exchange of information on March 12, 1989.

It started at CERN

At that time, the British computer scientist was working at the European nuclear research center CERN and had the problem that parts of the laboratories are located on Swiss territory and other parts on French territory. Because the two countries had different network infrastructures, he developed a system that was supposed to facilitate the exchange of information across borders. This original programming code comprises 9550 lines and has since dictated the basic structures of the Internet: the page description language HTML and the transfer protocol HTTP and the identifier URI. A revolution – not just for the scientific world for which the project was actually intended.

Digital collector’s item

Even if the code has long been “open source” – that is, freely accessible to everyone – it is now going under the hammer: the original files, provided with a time stamp and a signature from Berners-Lee, together with a digital poster that visualizes the source code and a letter from the scientist from 1989 in which he describes his project. Everything is conveniently packed in a so-called NFT – a “non-fungible token”. This is a kind of digital certificate of authenticity that is stored on a so-called blockchain. It should prove that the virtual object is unique – even if any number of digital copies can exist. The collector’s item of the digital age, so to speak.

Minimum bid $ 1000

As a computer scientist, it is only logical to auction his invention as such an NFT, says Berners-Lee. It feels right to put your signature under an all-digital artifact. The online auction lasts a week and starts with a minimum bid of $ 1000. The proceeds will go to a foundation.

After the auction houses had long blocked the auctioning of such NFTs, they have been doing this for some time good sales with digital art . Most recently, the auction of works by crypto artist Pak at Sotheby’s raised $ 17 million. At Christie’s, an NFT of a collage by digital artist Beeple changed hands for just under $ 70 million

Sports car manufacturer What Porsche is planning for the electric future

Status: 06/22/2021 9:24 a.m.

As a rule, Porsche tests new technology first on the race track – including a new high-tech battery. Because there are no suitable batteries on the world market, Porsche will produce them in-house in the future.

From Tim Diekmann, SWR

If you sit in the new Porsche Taycan, you don’t have to do without the usual sound. Although the first fully electric Porsche should glide almost silently across the street, it sounds either like a bubbling sports car or – when accelerating – like an intergalactic rocket. Porsche calls this “Electric Sport Sound” – because the Swabian car manufacturer does not want to deliver its newest vehicle completely without sports car noises. The luxury sports car, which Porsche sold 20,000 times worldwide last year, is only supposed to be the beginning of an electromobility initiative.

High-tech battery made in Germany

In just two years, every third Porsche should be equipped with an electric motor – as a hybrid or fully electric. For this, Porsche needs lots of powerful batteries. But they are hard to find on the world market, says Porsche boss Oliver Blume: “We need high-performance cells for our electric sports cars. But we can’t find them anywhere at the moment. That’s why we develop and build these cells ourselves.” The first battery cells are expected to roll off the assembly line from 2024, initially for around 1,000 vehicles per year. “The focus will initially be on small series for racing and high-performance vehicles. In the future, however, this is not just about racing cars,” explains Blume at the official presentation at the Porsche Development Center in Weissach. In the first step, innovative technologies are usually only developed for a limited high-tech application, “but once the innovations have proven themselves there, they will gradually establish themselves across the board. That must be our goal. At Porsche, that’s what we call it Principle: from motorsport to series production. ”

Range model Tesla

For battery cell production, the Stuttgart-based company is working with the German company Customcells, which it claims to be a world leader in the development of lithium-ion battery cells. The joint venture operates under the name Cellforce Group.

According to automotive expert Stefan Bratzel from the Center of Automotive Management in Bergisch-Gladbach, it is logical that, after Volkswagen, Porsche is now also relying on the production of its own battery cells: “The battery cell accounts for the largest part of the car’s added value, and it has a lot of innovation potential . Automobile manufacturers who develop competencies in this area have a long-term competitive advantage. ” According to Bratzel, Porsche should not chase after the competition for the US electric car manufacturer Tesla, but rather must lead the way as an innovator.

New battery technology promises many advantages

According to the head of electrochemical energy technologies at the Center for Solar Energy and Hydrogen Research in Baden-Württemberg (ZSW), Markus Hölzle, the batteries as we know them today should still develop their potential: “Everything can, must and will be improved Above all, however, the cost of battery cells must be reduced further. And the energy density must also increase so that the batteries become more compact. ” The ability to recharge quickly is also important. To do this, Porsche wants to work with so-called silicon anodes, which “has two major advantages over the previously used carbon: it improves the ability to charge quickly and increases the energy content,” explains Hölzle. But now Porsche must first show that they can do it.

But while Porsche is still planning the future, competitor Tesla is already building the world’s largest battery cell factory in Grünheide near Berlin and promises a production capacity of 100 gigawatt hours per year, a thousand times as much as Porsche’s subsidiary Cellforce Group.

Climate neutral by 2030?

The focus on e-mobility and the setting of climate targets is an important step for the brand, emphasizes car expert Bratzel. “Porsche is a brand that nobody really needs, but many people want to have it because of its positive image. And I believe that it is becoming more and more important for the Porsche clientele in particular to say: ‘I have a sports car and still drive in a climate-friendly way . ‘”

Climate protection has long since become an image factor. This also shows the ambitious goal of the Swabian car manufacturer to be “balance sheet CO2-neutral” by 2030 and thus earlier than Daimler (planned for 2039) or Volkswagen (planned for 2050).

Environmentalists are skeptical

The environmental protection organization Greenpeace is skeptical whether Porsche will really be climate-neutral by 2030. “Unfortunately, ‘climate-neutral’ on the balance sheet ‘usually means that in the end generously cheap CO2 credits are bought from offsetting projects instead of consistently reducing CO2,” says Benjamin Gehrs from Greenpeace. With its large SUVs, Porsche consumes an unnecessarily large amount of resources. Porsche must also get out of the business with climate-damaging diesels and gasoline engines faster and more consistently than before.

So will the Porsche 911 possibly soon hit the streets as an electric car? Unlikely. In addition to battery cell technology, Porsche is also working on the development of synthetic fuels, so-called eFuels, which are to be produced using renewable electricity. Artificial sports car sound, as in the Taycan, is then unnecessary. At Porsche, the first step is to advance research in the field of battery cell development. The federal and state governments support the project with 60 million euros

A heart cell organ that can beat like a real heart. Photo: livescience According to sciencemag.org, this mini organ (cell organelle) mimics the real heart of a 25-day-old human embryo and could help solve many mysteries, such as why children’s hearts don’t have scars. after having a heart attack. Not involved in the new study, but Zhen Ma, a cardiac organelle development bioengineer at Syracuse University, says it’s a great study, and the experiment is important in understanding Congenital heart defects and human heart formation. This process has so far relied solely on animal models. Although other mini-organs such as the brain, intestines, and liver have been grown in the lab for more than a decade, the heart cell organ presents a more challenging challenge for scientists.
The first cardiac organoids were created from mouse heart cells. They may beat on a lab plate, but they look like a bunch of heart cells, not a real heart. According to Aitor Aguirre, a stem cell biologist at Michigan State University, the cardiac organelle needs to function. With the heart, one wants the heart cell organ to have chambers and function to beat in rhythm. Watch a video of a mini heart beating in the lab (source: Sciencemag.org): To create an embryonic-like self-organizing heart cell organelle, the authors of the new study programmed human pluripotent stem cells (cells that have the ability to develop into any type of tissue). which) for this cell to turn into other types of heart cells. They wanted to create three layers of cells in the wall of the chambers of the heart, one of the first developing parts of the heart. Next, they embedded these stem cells in different concentrations of growth-promoting nutrients. They tried until they found a recipe to get these stem cells to form tissue in the correct order and shape in the embryo. After a week of development, the cardiac organelle was structurally equivalent to the heart of a 25-day-old embryo. At this stage, the heart has only one chamber, which will later be the left ventricle of the mature heart. Cardiac organelles are only about 2mm in diameter and have the typical major cell types in this stage of development: myocytes, epithelial cells, fibroblasts, and the epicardium. They also have a clear chamber that beats at a rate of 60-100 beats per minute, similar to the heart rate of embryos of the same age. Lead study author Sasha Mendjan, a stem cell biologist at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences, said: “When I first saw it, I was surprised that these chambers had self-forming. What’s amazing is that you see right away whether this experiment works and if this organelle is working, because it has a pulse.” Scientists were able to study heart formation in unprecedented detail. Photo: livescience The mini-heart has so far been more than three months old in the lab and will help scientists monitor the heart’s development in unprecedented detail. They can know the source of heart diseases such as congenital heart defects in children and heart cell death after a heart attack. Mendjan and his colleagues also frozen organelles to test their response to injury. They found that cardiac fibroblasts, a type of cell responsible for maintaining tissue structure, travel to the site of damage to repair dead cells, as happens in children who have had heart attacks. Scientists have long wondered why children’s hearts can regenerate after being damaged without scarring, unlike adults. Mr. Aguirre said the next step would be to connect this organ of beating heart cells to a network of blood vessels and test its ability to pump blood. Mendjan’s team intends to find a way to modify the nutrient solution to produce a four-chambered heart cell organ. With this innovative heart cell organ, researchers were able to learn more about heart problems that can arise when the walls of the heart’s chambers begin to form. Meanwhile, Mr. Ma said that growing a more mature heart cell organ with all four chambers and structure is a matter of the future. He thinks this will take a decade to materialize.
