Taking a look at the future can be fascinating, especially when you think of some of the advances that are on the horizon. Some of these advancements include high speed trains and online doctors’ appointments. Another area that is attracting people’s attention is the use of artificial brain implants to reverse the aging process.
High-speed trains have become increasingly popular in Europe and Asia. These modern train cars can travel between dense urban centers, and can be as fuel efficient as air travel. Unlike aircraft, which run on kerosene, trains run on electricity. The power can be produced from a wider range of sources. It is also more fuel-efficient. There are a number of different kinds of high-speed trains. Some can travel at speeds of over 200 miles per hour. They can be equipped with tilting train sets or air brakes. However, while these trains may be good for the environment, they may not be the best option. A life cycle assessment of trains found that even the most energy efficient trains can’t be considered eco-friendly if they are not in service.
Artificial brain implants
In the future, people with paralysis might be able to move their hands and speak, thanks to an artificial brain implant. The device would be implanted into the person’s skull and would use electrodes to monitor and record neuronal activity. It could also be a part of a system that incorporates external sensors and AI control systems.
The brain is a highly complex organ. Scientists have already used conventional silicone implants to improve the functioning of the brain. However, these devices are limited in their power. There is still a great deal of work to be done before the devices can be trusted to perform well. Several academic groups are working to develop brain-stimulating devices. One company, Neuralink, has been studying the implant’s feasibility.
Reverse aging by reprogramming DNA
Reverse aging by reprogramming DNA is a growing field of research. Some researchers believe reprogramming can reverse the age-related decline of tissues and cells and possibly increase lifespan. But before the approach can be used as an anti-aging intervention, rigorous proof of its effectiveness is required.
A recent study from the Salk Institute for Biological Studies shows that reprogramming can turn back the aging process of mice. The researchers successfully restored vision in mice with damaged retinal nerves. They also showed that reprogramming can reverse age-related damage to neurons in the eye. In addition, the researchers found that reprogramming can reverse age-related changes in the epigenome, the chemical mark on DNA. These changes may affect gene expression and lead to cell dysfunction.
The Stanford team discovered a method to reverse the aging process of epigenetics. Using a virus, they injected the genes of reprogramming factors into the eyes of mice. This treatment prevented the death of the retinal ganglion cells.
Online doctor’s appointments
Online doctor’s appointments are a great way to get high quality medical care without leaving your home. However, it’s important to be aware of some of the challenges that come with this type of treatment.
The first obstacle is that online doctors do not provide all of the services that an in person primary care physician offers. Some offer only a few services, while others specialize in chronic care, urgent care, mental health, weight management, and other types of care.
Another challenge is that patients who are unable to see a provider in person may have a hard time making an appointment with the right technology. For example, elderly or disabled people may have trouble using smart devices to schedule their appointments.
In addition, patients who require medication or physical examinations might not be able to make an appointment. These are reasons why many healthcare providers have shifted to virtual “telehealth” appointments.
Restoration of extinct species
De-extinction is the process of purposely adapting a living organism to perform the function of an extinct species. It can save living animals from extinction and restore an ecosystem. However, de-extinction remains a controversial issue and continues to spark debates and ethical issues.
In order to revive extinct species, scientists must develop a new species that has genetic characteristics that can survive in the wild. Scientists can use a variety of breeding techniques to create a replacement population. Some of the most popular methods used to revive extinct animals are cloning, back-breeding, and artificial selection.
The International Union for Conservation of Nature defines de-extinction as the generation of “faithful replicas” of an extinct species. These animals are created by manipulating DNA to mimic the extinct gene’s sequence.
