If December 22’s launch goes as planned then the engineers behind the $10 billion James Webb Space Telescope (JWST or “Webb” for short) are in for a nervous Christmas.

Forget that it was originally conceived in the 1990s and was first expected to launch in 2007. Forget also the initial rocket launch—usually viewed as the most nerve-wracking moment. This time it’s not the European Space Agency’s Ariane 5 rocket—due to lift Webb into space from the Guiana Space Center, Kourou, French Guiana on December 18, 2021—that’s giving engineers sleepless nights. It’s the 29 days of “space origami” they’ll have to endure after the launch as Webb unfolds from its collapse state into a “giant sunflower.”

You see, the technological marvel that is Webb is fully assembled, but folded into the 5.4 meter/17.7ft. fairing of the Ariane 5 for launch—the largest rocket fairing NASA could find. When it’s in-situ a whopping million miles/1.5 million kilometers from Earth at the second Lagrange point (L2) —almost certainly too far away for astronauts to fix if the worst happens—it will resemble a huge sunflower once unfurled.

And it would create 4.7 million long-term jobs.

The United States’ energy system that’s running completely on wind, water, and solar, combined with storage, would not only avoid blackouts but also lower energy requirements and consumer costs, a Stanford University study has shown. In addition, this would create millions of jobs, improve health, and free up land for various other purposes.

This is incredibly important because, for some people, a future powered by renewable energy isn’t feasible due to concerns about blackouts driven by inconsistent electricity sources. Take, for example, the grid blackouts caused by extreme weather events in California in August 2020 and Texas in February 2021.

The auto-retracting system can be deployed when solar energy is needed.

California-based energy firm Xponent Power developed an auto-retracting Xpanse Solar Awning that can be deployed if and when solar energy is needed, a report from New Atlas reveals.

With ultrafast decoy targets launching from the biggest plane ever made.

The U.S.-based aerospace company Stratolaunch announced that the company has signed a research contract with the Missile Defense Agency (MDA), which is a part of the U.S. Department of Defense (DoD), on hypersonic flight test services.

The DoD has been focused on hypersonic missiles for a long time now, mainly because of the significant threats they present such as difficulties in detecting, tracking, and intercepting due to being able to reach high speeds with the ability to maneuver along a flight trajectory.

Like a cybernetic pelican.

In all our coverage of air taxis that include wing designs, propulsion technologies, flight endurance, top speeds, we have surely not come across something so radical as this intriguing piece called PHRACTYL. If this appears to you like a bird that has mistakenly grown a pair of propellers at first glance, you are right on spot.

While birds have been the source of inspiration for human flight, after the success of the Wright Brothers, the flat wide wings have become a standard in aviation and technological advancements have happened on getting more lift from these wings. However, the engineers at PHRACTYL have dumped this conventional wisdom for a radically unique design that resembles a bird’s wing. But that’s not where they have stopped. The tail and the landing gear are no different, giving the aircraft the appearance of a bird.

After DeepMind’s breakthrough in protein folding last year, Alphabet will double down on artificial intelligence in biology and health with its new venture.

A newly approved eye drop hitting the market on Thursday could change the lives of millions of Americans with age-related blurred near vision, a condition affecting mostly people 40 and older.

Vuity, which was approved by the Food and Drug Administration in October, would potentially replace reading glasses for some of the 128 million Americans who have trouble seeing close-up. The new medicine takes effect in about 15 minutes, with one drop on each eye providing sharper vision for six to 10 hours, according to the company.

Toni Wright, one of the 750 participants in a clinical trial to test the drug, said she liked what she saw.

The brain is considered a very expensive organ to run.

Your brain may be leaking … energy, according to a new study that may explain why your noggin consumes 20% of the energy needed to keep your body running.

The study researchers found that tiny sacs called vesicles that hold messages being transmitted between brain cells may be constantly oozing energy, and that leakage is likely a trade-off for the brain being ready to fire at all times, according to a new study published Dec. 3 in the journal Science Advances.

Recently, a research team at Osaka University has successfully demonstrated the generation of megatesla (MT)-order magnetic fields via three-dimensional particle simulations on laser-matter interaction. The strength of MT magnetic fields is 1–10 billion times stronger than geomagnetism (0.3–0.5 G), and these fields are expected to be observed only in the close vicinity of celestial bodies such as neutron stars or black holes. This result should facilitate an ambitious experiment to achieve MT-order magnetic fields in the laboratory, which is now in progress.

Since the 19th century, scientists have strived to achieve the highest magnetic fields in the laboratory. To date, the highest magnetic field observed in the laboratory is in the kilotesla (kT)-order. In 2020, Masakatsu Murakami at Osaka University proposed a novel scheme called microtube implosions (MTI) to generate ultrahigh magnetic fields on the MT-order. Irradiating a micron-sized hollow cylinder with ultraintense and ultrashort laser pulses generates hot electrons with velocities close to the speed of light. Those hot electrons launch a cylindrically symmetric implosion of the inner wall ions towards the central axis. An applied pre-seeded magnetic field of the kilotesla-order, parallel to the central axis, bends the trajectories of ions and electrons in opposite directions because of the Lorentz force. Near the target axis, those bent trajectories of ions and electrons collectively form a strong spin current that generates MT-order magnetic fields.

In this study, one of the team members, Didar Shokov, has extensively conducted three-dimensional simulations using the supercomputer OCTOPUS at Osaka University’s Cybermedia Center. As a result, a distinct scaling law has been found relating the performance of the generation of the magnetic fields by MTI and such external parameters as applied laser intensity, laser energy, and target size.
