Hubble telescope set its sights on Pluto’s four small moons, which turn out to be eccentrics. Exciting tasks await NASA’s New Horizons spacecraft, which will reach the Pluto-Charon system in July

Astronomers see in Pluto and Charon a kind of planetary system en miniature, because both heavenly bodies revolve around a common gravitational center. The four remaining moons are not unaffected by this close relationship, as two scientists report in Nature. They not only observed the chaotic dance of two moons around Pluto, but were surprised by the characteristics of the quartet of small moons. Hopes are now pinned on NASA’s New Horizons robot, which will soon reach its destination after 9.5 years of flight and study the Pluto-Charon system up close. He was able to confirm the current observations and reveal even more surprising things.

Gated communities in cyberspace

Internet providers offer filters for certain value communities: Does the Web disintegrate into closed communities?

It is strange to observe how the Internet gradually adapts to real life again, or at least was able to do so. The fundamental characteristic of the Web is the possibility of setting hyperlinks or, by typing in URLs, of being able to access a page directly from a "place" to jump to another. Unlike in the real world, where places are characterized by different distances defined by space and time, virtual places in cyberspace are, at least in theory, all equidistant from each other and all equally accessible from any location. Huts are next to palaces, glittering and busy shopping malls are next to dingy alleys, government buildings are next to places where criminals hang out, children’s websites are next to red-light districts, offices are next to casinos. The space is replaced by the infrastructure, which determines, for example, how and with what capacity data is transmitted.

Another characteristic of the web is that the "Places" or "Building" is a "architecture" that determines, for example, the hierarchy of pages on a website, but that, in turn, in principle every page within a website can be reached directly without having to go through a specific path, which, for example, is "Entrance" over "aisle" and "floors" to a certain "Room" leads. If the URL of a certain page is known, i.e. it has been found by a search engine or "Deep Link" is given, then one can jump with the browser immediately from any place to another like with a teleporter.

Vienna summit decides to increase Frontex funds

Yesterday, eleven leaders and ministers from Slovenia, Croatia, Serbia, Albania, Hungary, Bulgaria, Romania, Macedonia, Germany and Austria met in Vienna to discuss the migration crisis. In addition, the meeting, hosted by Austrian Chancellor Christian Kern, was attended by EU Migration Commissioner Avramopoulos and EU Council President Tusk. Tusk explained that it was necessary to "practically and politically ensure that the Western Balkans route for illegal migration is closed forever." In February, German Chancellor Angela Merkel had strongly criticized the decision to stay on this route.

700 Executions in 25 years!

The USA celebrates an anniversary

Congratulations are in order: Last Thursday, the 700th anniversary of the. man has been executed since the reintroduction of the death penalty 25 years ago. Killed with an injection of poison in the state of Texas was 55-year-old Dennis Dowthitt, who eleven years ago allegedly sexually abused and then murdered his son’s 16-year-old girlfriend.

The execution was not broadcast live on television despite the anniversary. Guatemala is much more consistent in this respect. Bereits Mitte vergangenen Jahres zeigten die TV-Stationen des Landes live das amtlich verordnete Sterben zweier Menschen. Die Nachrichtenagentur AP beschrieb den Vorgang damals so:

France: cloning banned

However, the new bioethics law has given the green light to research on supernumerary embryos

While the German Bundestag has just decided to allow the import of embryonic stem cells only in exceptional cases – the Grande Nation has already offered its stem cell lines – the pan-European discussion about the hot potato "Bioethics" in France is already a step further: the question of when one should "Cell accumulation" The question of whether or not a human being worth protecting can be described as a human life worth protecting does not really seem to arise any more.

After years of back and forth, the government has finally decided to present a revision of the bioethics law in line with the signs of the times. However, it is not risking too much: February 22 is the end of the current legislative period.February is the end of the current legislative period, when a new National Assembly and the head of state will be elected. With the result that the currently available text of the law, which still has to pass the Senate in order to come into force, could soon look a little different. Or not.

Reality, realism and simulation

When do computer games actually become dangerous??

Nor are the opponents, who are fought against in killer games with all possible available means, actors controlled by other players or characters who act on the basis of a pre-programmed behavioral repertoire. In such scenarios, the graphical representation of humans or human-like beings is realistic at best. But the virtual actors should also become more human-like in their behavior – for example, in order to rehearse crisis and war operations in realistic simulations.

After the school massacres, there is a debate in Germany about whether killer games train players, especially children and young people, to be violent and thus facilitate or demand the spilling over of actions from virtual reality into reality through imitation, desensitization and familiarization with skills and behavioral models. Gamers themselves object that it is more about skill, i.e. a competition, which remains playful, because the killing of the characters visible in the game – it can also be their own representative in the game – is not understood as the killing of a real living being or even a human being. It is claimed that the separation of fiction. also Brutal Games(r)?).

To mark its 10th anniversary, the Hubble Heritage Project has released a striking image of NGC 3324 in the Carina Nebula

Ten years ago, the Hubble Heritage Project was launched to help bridge the gap between science and the general public and spark interest in astronomy. The project, based at the Space Telescope Science Institute (Baltimore), has set itself the task of reworking images taken with the Hubble telescope to make them aesthetically interesting and to present the universe from an artistic perspective.

Soder and Seehofer warn about "Corona-RAF" – and think not only right-open "lateral thinkers". A comment.

While across camps there is a growing lack of understanding for the sometimes contradictory measures taken by the federal and state governments to contain the corona pandemic – not least because of differing standards in the world of work and leisure – Bavaria’s Minister President Markus Soder (CSU) warns against a "Corona RAF". His party colleague Horst Seehofer blows the same horn as Federal Minister of the Interior.

Omar and the teeth of the president

Iraqi bloggers: propaganda via blog trolling?

Advent with the "Good": Bush obviously in the best mood. Two wise men from the Orient came to visit the President, who, as is well known, receives his orders directly from the superpower, which is America – the only one in the world "second to none!"- God Himself, and expressed their gratitude for their deliverance by the rude man. The coalition was doing a good job, they said, and as far as security in Iraq was concerned, they felt safe. After the American president learned that one of the visitors was a dentist, he showed Omar the president’s white teeth and asked for a new filling. What kind of people are they who put the most powerful man in the world in such a party joking mood?? Iraqi bloggers!

Omar and Mohamed from Iraq met last week as "representatives of the blogosphere" key reprasentatives of the U.S. political, media, and blogging elite (et al. a. Bush, Wolfowitz, Wallstreet Journal, Jeff Jarvis). The two brothers, together with the third brother Ali, maintain the blog "IraqTheModel.com". They have been invited to the United States for a good cause, "Spirit of America", the "Champions for Freedom, Democracy and Peace", and to find benefactors to donate to the Arab Blogging Tool project.
