‘A class of subluminal, spherically symmetric warp drive spacetimes, at least in principle, can be constructed based on the physical principles known to humanity today,’ the scientists say.


“Conceptually, we demonstrate that any warp drive, including the Alcubierre drive, is a shell of regular or exotic material moving inertially with a certain velocity. Therefore, any warp drive requires propulsion. We show that a class of subluminal, spherically symmetric warp drive spacetimes, at least in principle, can be constructed based on the physical principles known to humanity today.”

The scientists’ theories are based on the Alcubierre warp drive, named after theoretical physicist Miguel Alcubierre. In his paper’s abstract, published in 2000, he wrote that the drive world work by modifying spacetime.

While these tools will enable our society to reopen (and stay open) by improving detection of the virus, CRISPR will also have an important effect on the way we treat other diseases. In 2021, we will see increased use of CRISPR-Cas enzymes to underpin a new generation of cost-effective, individualised therapies. With CRISPR enzymes, we can cut DNA at precise locations, using specifically designed proteins, and insert or delete pieces of DNA to correct mutations.

As we deepen our understanding of the human genome and genetic disorders, patients with previously intractable diseases, such as sickle-cell disease and cancer, will benefit more widely from CRISPR-based therapies that are rapidly moving from the lab to the clinic. In 2019, sickle-cell patient Victoria Gray, for example, became one of the first patients in the world to receive CRISPR therapy for her genetic disease. She has already seen significant improvements to her health, including reduced pain and less frequent need for blood transfusions.

CRISPR will also allow us to act more boldly in the face of other important, interconnected issues such as food security, environmental sustainability and social inequality. The technology will help us grow more nutritious and robust crops, establish “gene drives” to control the spread of other infectious diseases such as Zika, and develop cleaner energy sources such as algae-based biofuels.

Researchers from the Polytechnic University of Valencia (UPV) have come up with and patented a new system for manufacturing beams that aims to revolutionize the architecture, construction and civil engineering sectors. They are manufactured with 3D-printed plastic pieces that can be assembled as if they were pieces of Lego adding a high-performance layer of concrete in the most compressed area.

Its advantages, according to its creators, are several: they weigh up to 80% less than concrete or metallic beams, which means that no heavy cranes or lorries are needed to carry and install them; they save time and money on labor and materials; and they can be printed and assembled in situ, which facilitates their installation anywhere, regardless of how difficult it is to reach. In addition to all of this, it uses recycled plastics as the raw material, giving a new life to this product and thus helping move towards more sustainable construction.

The development of these innovative beams is the result of almost three years of research. “Our goal was to propose an alternative to the current reinforced concrete beams. These are made using profiles built for the length of the piece, which requires expensive installation and are hard to transport,” says José Ramón Albiol, lecturer at the Higher Technical School of Construction Engineering (ETSIE) of the Polytechnic University of Valencia. Following numerous hours of tests and trials, the combination of 3D printing, plastics and concrete provided optimum results. And last October they patented the system.

This image captures about 80% of the test flight. The other 20% off camera is when Starship SN10 was hovering at 10 kilometers and slowly moving west just up and out of the camera view.

SpaceX is getting very close to landing these Starship prototypes. They lost three Starships currently SN8, SN9 & SN10. It’s estimated that Starship is four times as expensive as a Falcon 9 so a very rough cost is about $280 million for each Starship prototype.
