| One particle on two paths: Quantum physics is right Posted: 11 May 2022 09:35 AM PDT The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a two-path-interference experiment has been designed that only has to measure one specific particle to prove that it travelled on two paths. |
| Traveling to the centre of planet Uranus: Materials synthesis research and study in terapascal range Posted: 11 May 2022 09:35 AM PDT Jules Verne could not even dream of this: A research team has pushed the boundaries of high-pressure and high-temperature research into cosmic dimensions. For the first time, they have succeeded in generating and simultaneously analyzing materials under compression pressures of more than one terapascal (1,000 gigapascals). Such extremely high pressures prevail, for example, at the center of the planet Uranus; they are more than three times higher than the pressure at the center of the Earth. |
| Small, mini, nano: Gear units created from a few atoms Posted: 11 May 2022 05:57 AM PDT Ever smaller and more intricate -- without miniaturization, we wouldn't have the components today that are required for high-performance laptops, compact smartphones or high-resolution endoscopes. Research is now being carried out in the nanoscale on switches, rotors or motors that comprise of only a few atoms in order to build what are known as molecular machines. |
| Artificial cell membrane channels composed of DNA can be opened and locked with a key Posted: 10 May 2022 03:55 PM PDT Scientists describe the design and construction of artificial membrane channels, engineered using short segments of DNA. The DNA constructions behave much in the manner of natural cell channels or pores, offering selective transport of ions, proteins, and other cargo, with enhanced features unavailable in their naturally occurring counterparts. |
