In General Relativity, the fabric of space doesn’t remain static over time. Everything else depends on the details we measure.
When it comes to building the interior of a spacecraft, engineers often prioritize function over aesthetics, focusing on materials and hardware that are both safe and effective for executing the vehicle’s intended mission. But some scientists say it’s time to consider another crucial factor when designing a spacecraft’s insides: how it will affect the behavior of the passengers?
University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.
In the process, however, the researchers discovered a fundamental property of halide perovskites that may prove a barrier to their widespread use as solar cells and transistors.
Alternatively, this unique property may open up a whole new world for perovskites far beyond that of today’s standard semiconductors.
Prof Claudia de Rham’s ‘massive gravity’ theory could explain why universe expansion is accelerating.
Early morning exposure to blue wavelength light can help heal the brain following mild traumatic brain injury (mTBI), new research suggests.
Results of a small, randomized controlled trial showed blue-light therapy improved brain structure and function, cognition, and sleep in this patient population.
“We found that blue-light therapy improved patients’ daytime sleepiness,” study investigator William D. ‘Scott’ Killgore, PhD, told Medscape Medical News. “So those who got the blue light were less sleepy 6 weeks later than they had been at baseline.”
A new paper formulates and suggests laboratory experiments to confirm mass-energy-information equivalence.
Sometimes, being human involves tragedy: unexpected accidents can alter a person’s future, permanently changing how they need to approach their daily lives. Those with traumatic brain injuries suffer long-term mental and physical challenges, such as trouble with their working memory span, which can play a significant role in their education and longevity. However, if used properly, transhuman aids such as prosthetic limbs can provide solutions to human challenges.
Transhumanism, in a nutshell, is the idea that people can use technology to overcome biological limitations. Just as how we use rational means to improve our life experiences and the world around us, we can use such means to improve ourselves as organisms. It is simply a concept, not a tangible characterization of some futuristic cyborg.
There is reasonable fear that using such technologies would be tampering with nature. This is true. However, whether something is good or bad cannot be decided simply by asking whether or not it is natural. Plenty of natural things are horrible, such as diseases and parasites, where our moral interest is to intervene and improve these conditions. The question to ask is not whether the technology is natural, but rather, what are the various possible consequences that would arise from it, both desirable and undesirable, and the likelihood of each. People who are concerned that our species will stray too far away from what it means to be a ‘natural human’ forget how far we have already evolved as a species.
Astronauts who have looked down at planet Earth from the stillness of space often describe the moment as a life-changing experience.
Artificial-intelligence startup Pearl Inc. is using machine learning to analyze dental imagery, helping insurers pinpoint whether the same X-ray was used for more than one patient and whether a procedure was necessary.
The West Hollywood, Calif., company said its system has found thousands of cases in which dentists have used the same X-rays or other images to bill insurers for multiple patients.
The interior design of the International Space Station takes a back seat to technology—the opposite of the majestic and immaculate spacecraft you see in sci-fi blockbusters.
