6 most horror science ideas

These deadly viruses revive. Foxes eat human meat. The soldiers never sleeps. It is not a horror film but a bold idea of ​​today's scientists. Popular Science magazine has listed 6 most scary science ideas.

The most scary modern science ideas

1. Revive deadly virus

About 50 million people worldwide have died in the Spanish flu pandemic in 1918. Within 1 year, the virus suddenly deformed, humans became immune and the flu disappeared. In October 2005, a group of scientists at the Centers for Disease Control and Prevention recreated the genome of the virus from a victim's lung tissue in 1918, buried in Alaska, and revived the dead. time And now, it's there, in the lab, and still as dangerous as ever.

2. Every day 22 hours

A new drug can help people stay awake without any side effects. Darpa Research Center of the US Department of Defense tested the CX717 drug by sending soldiers to the front for 20 hours in 4 consecutive days. C sleeps 4 hours a day , these soldiers remain alert and energetic. Meanwhile, modafinil helps the civilians stay awake for 48 hours. And the next product armodafinil, waiting for the US Food and Drug Administration to approve, also helps people stay awake longer.

" This drug can be effective for a while, but it is impossible to replace sleep, " Dinges said.

3. Robots are not tolerant

The Korean government and Samsung Techwin have launched a weapon- equipped robot that automatically detects intruders as far as 4 kilometers away with high-resolution infrared cameras. Anyone who does not give the correct password for the system to recognize the robot's voice will be treated as an enemy and immediately suffers a series of warning bullets, tear gas or even real bullets.

4. Armor protects the earth

The latest plan to combat global warming sounds like a galactic war: Airborne clouds of tiny spacecraft can bend 1.8% of sunlight. out of the earth. Roger Angel at Arizona Space Observatory Laboratory came up with the initiative. Now, with financial support from NASA 's Advanced Institute of Concepts, he is creating materials that bend light. Machines weighing only a few grams that he imagined would be fired on L1 orbit, the earth's annual path. From that vantage point, the cloud consists of tiny ships that will cool the entire planet.

"Imagine that we have doubled the amount of CO2, tripled, quadrupled, the temperature of the earth has risen to more than 10 degrees, and we still hold it back. Then one day something is broken, "The ships will disappear. The earth will suffer sudden climate change. It will be a shock to the whole system," said climate expert Richard Alley at the University of Pennsylvania.

5. The most aggressive carnivore

Scientists at the Institute of Genetics and Cytology in Novosibirsk, Russia, have bred selectively to create extremely aggressive silver gray foxes . After 36 generations, about 200 foxes are always screaming, rushing to pounce when people approach their pen.

Why is that? The late geneticist Dmitry Belyaev initially performed his experiment for the sake of peace rather than finding the most pure ones. Since 1959, Belyaev has begun to breed friendly fox generations, essentially repeating the process of purification for 12,000 years in a short period of time. The project continues to show how many foxes have become obedient dogs under human hands.

But in 1970, to discover more aspects of animal behavior, the program began to breed fierce animals."Having animals in different extremes, you can learn the evolution of each personality , " said Sergio Pellis, a scientist at the University of Lethbridge, Canada.

However, the foxes cannot go anywhere. They live in metal stables in one of the most remote cities in the world. And even if they escape, they cannot survive long. These are just overly self-defense animals, they do not attack but can escape until starvation.

6. Regrowing limbs

Amphibians can re-grow limbs. But mammals do not. " It's really an important issue ," said cell biologist Ken Muneoka at Tulane University. Now two groups of biologists have repaired the defect of evolution in a $ 7.6 million project funded by Darpa. The goal is to create a germ of stem cells of mammals - the germ cell that forms a new amphibian limb. For 4 years, Darpa wanted a rat toe to regrow. And research on people will be the next step.

Research will be able to change the lives of those with amputated hands. Scientists believe that the mixing of cellular and extracellular components, which may be hormones, vitamin A, fibroblasts, and covering up limbs, may lead to regrowth."We can create a person for 9 months, an arm or leg is not a problem," Badylak said.
