International Journal of Occupational Safety and Ergonomics reveals that a significant number of office employees use computers for over four hours daily. This kind of sedentary work routine can lead to potential health hazards. It’s well known that spending all day in front of a computer can contribute to issues ranging from eye strain to cardiovascular diseases.

Dedication to typing for a considerable part of your work hours can also result in typing-related pain or injuries. Although jobs that necessitate typing may not be perceived as high-risk for injuries, Alan Hedge, director of the Human Factors and Ergonomics Laboratory at Cornell University, communicated to The Seattle Times that the weekly volume of typing an office worker endures can accumulate significantly. Hedge noted that someone typing at an average pace for seven hours daily will, throughout a standard five-day work week, subject their fingers to pressure that amounts to over 20 tons of force. Furthermore, the stress inflicted on your wrists and joints from typing and computer use is also noteworthy.

Some individuals seek to mitigate discomfort and injuries by choosing ergonomic keyboards. However, efforts might prove futile, as indicated by research from the University of Pittsburgh School of Health and Rehabilitation Sciences, which suggests that more expensive ergonomic keyboards may not provide the expected advantages.

Artemis II is prepared for its monumental lunar expedition. The colossal rocket and Orion spacecraft are currently located at Launch Complex 39B after a lengthy, four-mile trek from the assembly facility, where they completed final inspections. This was not NASA’s initial rollout for the Artemis II mission, but the agency is optimistic it will be the final one. Mission organizers are aiming for an April 1, 2026 launch window. Once ignition occurs, it will take approximately three minutes to reach NASA’s designated boundary of space, and about eight minutes to enter orbit.

The launch demands 8.8 million pounds of thrust, equivalent to the output of 326 F-16 fighter jet engines. Approximately one minute into the ascent, the rocket reduces its throttle for approximately 25 seconds at Max Q, the point of peak aerodynamic pressure, as it navigates through the thick lower atmosphere. Once it breaks through, Orion will continue to gain speed, reaching nearly 3,200 miles per hour. At around 2:09 into the flight, the solid rocket boosters will separate before Orion attains the boundary of space.

How quickly Artemis II ascends to space post-liftoff

The subsequent phase activates the power of the shuttle era. Four RS-25 engines, refurbished from the shuttle program, will propel the spacecraft to 17,500 mph, the minimum velocity required to achieve a stable orbit around Earth. This phase extends from the edge of space into orbit, nearly 100 miles above Earth. The majority of the thrust is directed forward rather than upward.

As the crew experiences microgravity just eight minutes into their 10-day adventure, the RS-25 engines will cease operation, causing the crew to become weightless. The spacecraft will glide in orbit for about 24 hours, awaiting the exact moment when Orion’s Orbital Maneuvering System Engine (OMS-E) executes the translunar injection (TLI) burn that propels Orion towards the moon.

The crew will journey over 230,000 miles to the moon, taking approximately three to four days to achieve its orbit. The Artemis II mission does not involve landing. Instead, the crew will remain about 4,000 to 6,000 miles above the lunar surface as NASA aims to evaluate whether Orion can adequately support a crew in deep space, while simultaneously allowing them to practice navigation and control systems. After orbiting the moon, Orion will return home, splashing down in the Pacific Ocean near San Diego roughly ten days post-liftoff.

The significance of Artemis II

NASA has had to postpone the mission multiple times to ensure the spacecraft remains intact and functional during its initial phases. The latest Artemis II delay was due to a helium pressurization complication. There is a great deal at stake since Orion will transport four astronauts around the moon for the first time since 1972. Onboard Orion are Christina Koch, Victor Glover, and Jeremy Hansen, who will be the first woman, first person of color, and first Canadian, respectively, to reach the vicinity of the moon. NASA veteran Reid Wiseman will be in command.

The rocket utilizes engines from the space shuttle program, but they will facilitate achieving something those shuttles never accomplished: Accelerating to speeds of nearly 25,000 mph upon returning from the moon. Artemis II will represent a significant advancement in maintaining a human presence on the moon. Currently, it remains uncertain when — or if — the subsequent mission, Artemis III, will transport humans to the moon. NASA announced a delay of the planned journey in early March 2026 due to challenges with Artemis II.

numerous “Star Wars” release dates consistently on the horizon. However, several titles have been cancelled or put on hold, such as Taika Waititi’s initiative or those from Kevin Feige, Rian Johnson, and probably the new Ben Solo movie. There’s no point in lamenting over spilled milk, though, because there remains a wealth of content on the way — some of which is bound to be excellent, and some perhaps not. Thus is the ever-swaying pendulum of releases from a galaxy far, far away.

Gazing into the future, certain forthcoming projects generate enthusiasm solely based on their titles and context. “The Mandalorian and Grogu” launches shortly, and it will be reintroducing “Star Wars” to the big screen in a significant manner. Since that is so imminent (and technically out of development), we chose to leave it out of this list — but make no mistake, it is guaranteed to stir things up. If you’re eager about what else looms on the horizon, here are some of the other thrilling “Star Wars” projects presently in development or arriving soon.

which isn’t too terrible for battery life), but even that feels sluggish when compared to an innovative technology that utilizes laser power to charge quantum batteries.

Recently, researchers in Australia revealed they had made significant progress in the area of “quantum batteries.” The research, published in Light: Science & Applications, showcased their ability to employ a strong laser pulse to bombard the battery’s “optical microcavity,” which contains photodiode solar cells, resulting in a “superabsorption” event. The charging rate was so rapid that researchers could only capture it using ultrafast spectroscopy, a technique used to analyze occurrences in the nanosecond to femtosecond (10^-9 seconds to 10^-15 seconds) intervals. Blinking appears to occur at a snail’s pace when compared to this phenomenon.

In contrast to traditional batteries or solid-state batteries, quantum batteries, as their name suggests, harness the principles of quantum mechanics (a semi-theoretical domain of physics that posits that specific microscopic entities exist as both particles and energy) to accumulate and deliver electricity. The battery’s ability to utilize a realm of physics that expands our comprehension of reality is what enables the device to soak up energy and charge at rates beyond the grasp of most individuals.
