SpaceX nails second Falcon nosecone recovery in one month

Posted by in categories: internet, military, satellites

SpaceX has successfully recovered two pairs of Falcon 9 payload fairings (nosecones) – one twice-flown – in one month after twin ships GO Ms. Tree and GO Ms. Chief returned to port on July 2nd.

Around 45 minutes after Falcon 9 B1060 lifted off for the first time with the US military’s third upgraded GPS III satellite in tow and around 40 minutes after the rocket’s payload fairing deployed, both fairing halves gently splashed down in the Atlantic Ocean just a few miles apart. Lacking their main recovery nets in an odd configuration, Ms. Tree and Ms. Chief both fished one half out of the ocean with smaller secondary nets before placing the fairings on their decks for technicians to secure them.

A little more than two weeks prior, both ships were in the midst of recovering the Starlink-8 mission’s twice-flown fairings from the ocean, safely returning them – intact – to shore for the first time since SpaceX began fairing reuse. As SpaceX itself noted at the tail end of its GPS III SV03 webcast, the intact recovery of the mission’s fairing halves all but guarantees that they’ll be reused in the near future.

The lightest electromagnetic shielding material in the world

Posted by in categories: chemistry, materials

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals. High-frequency electromagnetic fields can only be shielded with conductive shells that are closed on all sides. Often thin metal sheets or metallized foils are used for this purpose. However, for many applications such a shield is too heavy or too poorly adaptable to the given geometry. The ideal solution would be a light, flexible and durable material with extremely high shielding effectiveness.

Aerogels against electromagnetic radiation

A breakthrough in this area has now been achieved by a research team led by Zhihui Zeng and Gustav Nyström. The researchers are using nanofibers of as the basis for an aerogel, which is a light, highly porous material. Cellulose fibers are obtained from wood and, due to their , enable a wide range of chemical modifications. They are therefore a highly popular research object. The crucial factor in the processing and modification of these cellulose nanofibres is to be able to produce certain microstructures in a defined way and to interpret the effects achieved. These relationships between structure and properties are the very field of research of Nyström’s team at Empa.

A three-dimensional phase diagram of heavy-fermion compound with competing quantum phases

Posted by in categories: particle physics, quantum physics

URu2Si2 is a metal that belongs to the family of heavy-fermion compounds in which several quantum phases (e.g., magnetism and superconductivity) can compete or coexist. These metals exhibit small energy scales that are easy to tune, a characteristic that makes them ideal for testing new physical ideas and concepts.

For instance, researchers have often used these compounds to test theories related to , quantum criticality and unconventional superconductivity. Studying heavy-fermion metals could ultimately unveil new physical properties of other correlated-electron materials that have shown promise for a wide range of applications, such as .

A research team at the National Laboratory of High Magnetic Fields (LNCMI/CNRS) in France and Université Grenoble Alpes, in collaboration with researchers at Okayama University and Tohoku University in Japan, recently carried out a systematic investigation of URu2Si2 under a combination of high pressures and high magnetic fields. Their paper, published in Nature Physics, maps out a phase in the material that is so far poorly understood, delineating a complex three-dimensional phase diagram.

Just 50% of Americans plan to get a COVID-19 vaccine. Here’s how to win over the rest

Posted by in categories: biotech/medical, health

Even before the pandemic, public health agencies around the world were struggling to counter increasingly sophisticated efforts to turn people against vaccines. With vaccination rates against measles and other infectious diseases falling in some locations, the World Health Organization (WHO) in 2019 listed “vaccine hesitancy” as one of 10 major global health threats.

To stop the pandemic, the world’s public health experts must win the coming “story war” over vaccine misinformation.

Hydroxychloroquine lowers COVID-19 death rate, Henry Ford Health study finds

Posted by in categories: biotech/medical, health

Well this is interesting:

A Henry Ford Health System study shows the controversial anti-malaria drug hydroxychloroquine helps lower the death rate of COVID-19 patients, the Detroit-based health system said Thursday.

Officials with the Michigan health system said the study found the drug “significantly” decreased the death rate of patients involved in the analysis.

The study analyzed 2,541 patients hospitalized among the system’s six hospitals between March 10 and May 2 and found 13% of those treated with hydroxychloroquine died while 26% of those who did not receive the drug died.
