Top 5 most populous megacities worldwide
The United Nations has released fresh data on the most populous cities in the world. Let's take a look at the top megacities by population.
There is still a long way ahead for the scientists to achieve new medical breakthroughs. The latest technologies in medicine make it possible to save thousands of lives daily. In our photo gallery, read about 4 medical advances to look forward to in the next 50 years.
Saving premature babies
According to statistics, only 10% of infants in the US are born premature. By contrast in Russia, the number of preterm delivery and newborn mortality is much higher. Medical specialists around the world are working on the solution to tackle this problem and improve the sad statistics.
In 2017, scientists from the Children's Hospital of Philadelphia created an artificial womb to support the development of early born lambs. As the research results showed, the fetus located inside the artificial uterus for 4 weeks displayed positive changes. In the future, these technologies can be applied to premature babies.
Reducing the shortage of donor organs
Currently, there is an acute shortage of donor organs all over the world which is also a reason for increased mortality. To solve this problem, scientists are trying to grow human organs within the pig’s embryos. These animals have organs similar to humans in size and shape. Besides, pig’s organs develop faster than the human ones. At the same time, it is very difficult for cells of one species to take root in another species organism.
In 2016, scientists managed to grow human stem cells inside a pig embryo. This achievement became a real breakthrough in medicine.
Repairing damaged organs with plants
Recently, scientists from Worcester Polytechnic Institute (WPI) in Massachusetts made a breakthrough step in modern medicine. A team of specialists managed to grow blood vessels from spinach leaves that were able to transport water. After that, the plant cells were replaced with muscle cells from the human heart. In this way, it enabled the plant veins to pump water as they would do it in the real heart.
This discovery gives hope that in the nearest future it will be possible to treat damaged organs with plants, from spinach to broccoli, instead of transplanting them.
Regeneration
Regeneration of the living tissue is another ambitious goal of modern medicine. Every year, 185 thousand amputations are carried out in the United States. The field of prosthetics is rapidly developing now which allows people to use nano-technological prostheses that fully replace the lost limb.
However, scientists want to take a step further. In particular, they have paid special attention to animals, such as axolotl, with the ability to regenerate new parts of their body, including limbs, lungs, and even eyes. Scientists have already identified the genes responsible for regeneration ability in these animals. Perhaps, one day it will be possible to create a medicine that stimulates tissue growth in humans.

Deepfake is a technology based on artificial intelligence to create ultra-realistic fake videos, audio, and images featuring real people. In recent years, it has gained incredible popularity, evoking both admiration and concern. Celebrities, whose faces are often used for such purposes, have felt its impact most acutely. In this article, we will discuss five of the most "deepfaked" individuals who have become the main victims of this emerging technology.
The biggest news of recent days has been Donald Trump's victory in the US presidential election. This event has caused a stir around the world, reminding us of the significant role a US president plays in both national development and international affairs. Throughout US history, several presidents have dramatically reshaped the country's domestic landscape and strengthened its influence abroad. Let's take a look at some of the most influential
