coastguard. it is only one line but it is sufficient for them to put it out and they have not been doing that to the course of the last few days so i suspect that is significant, but the detail also is very significant and certainly it is pushing back, normally when they talk to us and update us they give themselves more time to actually analyse what they have actually found. absolutely right and we have been waiting for this information all morning essentially. this urgent search has been going on for a few days now. every day the coastguard has been updating reporters and the press in the afternoon, but this particular press conference is going to be crucial because they will hopefully release more details on what those rovs remote operated vehicles have indeed discovered near the site of the titanic. i want to bring it our reporter carl because he has been here for a few days following all of this. you are at the press conference yesterday as well. they were really looking
we re going to get our first public glimpse of princess catherine since christmas. what the palace said today about her cancer battle and her plans to try and resume some of her royalty duties. but leading this hour yesterday, today and for the next two weeks, the us supreme court will dominate the political conversation in this country. today, it s a major guns decision. the justices ruling six to three to strike down a federal ban on bump stocks. the ban was initially approved by donald trump 2018 after the massacre at a las vegas music festival, you might remember a gunman killed 58 people at the outdoor concert when he set up perch on the 32nd floor of the mandalay bay hotel and open fire for at least ten minutes by the time police breached the room, they say the shooter was dead, but they found 23 weapons in the room 12 with firearms, with bump stocks attached. that attack, by the way, is the deadliest mass shooting in modern american history. so i know some of you are p
catastrophic failure of the - indicate? in the case that this is a catastrophic failure of the main i catastrophic failure of the main housing, the submersible had a carbon fibre main housing and titanium and caps of this would have been subject to incredibly high pressures. if you translate that to actual forces and weights, the equivalent force in pressing the vessel would have been similar to the weight of the eiffel tower. we are talking about weights similar to several thousands to tens of thousands of tonnes. so if this were a catastrophic failure of the main housing it would have happened in an instant. we would not be expecting parts of the carbon fibre housing to be intact. potentially parts of the titanium components may be worn but still intact. but we are talking about a very powerful implosion of the main housing. fine

Tungsten has the highest melting point of all metals, 3,422 degrees Celsius. This makes the material ideal for use at high temperatures in e.g. space rocket nozzles, heating elements of high-temperature furnaces, or the fusion reactor. However, the metal is highly brittle and, hence, difficult to process. Researchers of Karlsruhe Institute of Technology (KIT) have developed an innovative approach to making this brittle material soft. To process tungsten, they have determined new process parameters for electron beam melting.
Tungsten is a metal with very attractive properties: It is corrosion-resistant and as heavy as gold. In the form of tungsten carbide, it is as hard as diamond. And it has the highest melting point of all metals, 3,422 degrees Celsius. However, the metal is highly brittle at room temperature. Due to its properties, tungsten is dif
