SpaceX’s Starship SN4 launch vehicle prototype explodes after static engine fire test

Posted by in category: space travel

SpaceX had just conducted yet another static fire test of the Raptor engine in its Starship SN4 prototype launch vehicle on Friday when the test vehicle exploded on the test stand in Boca Chica, Texas. This was the fourth static fire test of this engine on this prototype, so it’s unclear what went wrong versus other static fire attempts.

This was a test in the development of Starship, a new spacecraft that SpaceX has been developing in Boca Chica. Eventually, the company hopes to use it to replace its Falcon 9 and Falcon Heavy rocket, but Starship is still very early in its development phase, whereas those vehicles are flight-proven, multiple times over.

SpaceX had just secured FAA approval to fly its Starship prototype for short, suborbital test flights. The goal was to fly this SN4 prototype for short distances following static fire testing, but that clearly won’t be possible now, as the vehicle appears to have been completely destroyed in the explosion following Friday’s test, as you can see below in the stream from NASASpaceflight.com.

Europe bets R&D spending will bring jobs to battered economy

Posted by in categories: biotech/medical, economics, employment

The European Union wants a massive dose of research spending to lift it out of what could be the worst recession in its history. Last week, as part of a €1.85 trillion budget and pandemic recovery proposal, the European Commission, the EU executive arm, unveiled plans to pump €94.4 billion into research over 7 years, nearly €11 billion more than originally planned for the program, called Horizon Europe. But not everyone thinks the money is the best medicine.


Horizon Europe gets €13.5 billion to spend fast, spur growth.

Joined nano-triangles pave the way to magnetic carbon materials

Posted by in categories: chemistry, nanotechnology, particle physics

Graphene, a two-dimensional honeycomb structure made of carbon atoms with a thickness of only one atom, has numerous outstanding properties. These include enormous mechanical resistance and extraordinary electronic and optical properties. Last year a team led by the Empa researcher Roman Fasel was able to show that it can even be magnetic: they succeeded in synthesizing a molecule in the shape of a bowtie, which has special magnetic properties.

Now, researchers report another breakthrough. Theoretical work from 2007 predicted that graphene could exhibit if it were cut into tiny triangles. Over the last three years, several teams, including the Empa team, have succeeded in producing the so-called triangulenes, consisting of only a few dozen , by chemical synthesis under ultra-high vacuum.

Graphene and 2-D materials could move electronics beyond ‘Moore’s law’

Posted by in categories: computing, mobile phones, nanotechnology, particle physics

A team of researchers based in Manchester, the Netherlands, Singapore, Spain, Switzerland and the U.S. has published a new review on a field of computer device development known as spintronics, which could see graphene used as building block for next-generation electronics.

Recent theoretical and experimental advances and phenomena in studies of electronic spin transport in and related two-dimensional (2-D) materials have emerged as a fascinating area of research and development.

Spintronics is the combination of electronics and magnetism, at the nanoscale and could lead to next generation high-speed electronics. Spintronic devices are a viable alternative for nanoelectronics beyond Moore’s law, offering higher energy efficiency and lower dissipation as compared to conventional electronics, which relies on charge currents. In principle we could have phones and tablets operating with spin-based transistors and memories.

The mystery is over: Greek mathematician successfully solves 78-year-old maths problem

Posted by in category: mathematics

A Greek mathematician has found the answer to a mind boggling maths problem that has remained unanswered for 78 years – until now.

Associate Professor of Mathematics Dimitris Koukoulopoulos together with Oxford University research professor James Maynard, has solved the Duffin and Schaeffer Conjecture.

First expressed in 1941 by mathematicians R J Duffin and A C Schaeffer, the last time a mathematician showed promise in solving the problem was in 1990. But it wouldn’t be until 29 years later that it would be fully proven by Koukoulopoulos and Maynard – two relatively young mathematicians, both aged in their 30’s.

How DNA and RNA subunits might have formed to make the first genetic alphabet

Posted by in categories: biotech/medical, genetics

Understanding the prebiotic origins of the nucleic acids is a long-standing challenge. The latest experiments support the idea that the first nucleic acid encoded information using a mixed ‘alphabet’ of RNA and DNA subunits. RNA and DNA nucleosides might have emerged together on prebiotic Earth.
