Why do human drugs kill bacteria but not viruses?
On the earth, there will be viruses in any corner of life. Viruses depend on other life to survive and reproduce. They are between life and non-life. They are so simple that only a piece of genetic material is left, and a protective protein shell is wrapped on the outside.

Go Green? Enough Already
Drive a puny, fuel efficient car or hybrid; use an ugly little light bulb that emits a dull light and is hazardous when broken; wear a sweater in your own home in the winter and don’t be afraid to sweat in the summer; all in the name of "going green". I’m tired of being lectured to on how to live my life by elitists who don’t even follow their own rules. It’s time to say enough is enough. I would have no problem if conservation and recycling were spoken of in the context of energy efficiency and cost effectiveness, but the green movement has become an out of control religion based on what many experts now believe is a myth, man-made global warming. Americans are constantly bombarded by the media with this message of "going green" that is designed to give people a false sense of "doing good". In the process, they are willing to give up their individual rights one by one and without question. That is why "going green", which was once a cute little message, is now becoming an oppressive slogan.

What to expect from Egypt COP27 Climate Summit?
We are less than a month away from the climate summit COP 27th, which this year takes place in the luxury resort of Sharm El-Sheikh, in Egypt. This is the second time a Middle Eastern country hosts one of these summits. Morocco hosted the COP22 five years ago. However, since the last time world leaders met for the COP26, in Glasgow, UK, in November 2022, the world has changed a great deal. Russia has invaded Ukraine undermining Europe energy security; global inflation is at 40 years high, and we are headed to economic recession.

How Kenya is harnessing the immense heat from the Earth
rive along the dusty dirt road that winds through Kenya's Hell's Gate National park, past the zebra, gazelles and giraffes, and you'll see a plume of steam shooting skyward in the distance. Vehicles must sometimes swerve to avoid running over warthogs as they enter a vast valley dotted with dozens of steam vents – a factory of clouds.

If mosquitoes were to become extinct, would the ecosystem collapse?
Every day, Jitwadi Murphy opens a stuffy padlocked room at Walter Reed Army Institute of Research in Silver Spring, Maryland, to a swarm of malarial mosquitoes. She grinds up fish food and feeds it to millions of tsetse, then delivers unconscious mice for the many "pregnant mosquitoes" to suck blood from their abdomens - they suck 24 of these rodents dry each month. Murphy has studied mosquitoes for 20 years and has worked to limit the spread of parasitic organisms carried by mosquitoes. That said, Murphy says she'd still rather wipe mosquitoes out of the world altogether.

Why are we having summer when the earth is far from the sun?
Every moment, the Earth is revolving around the Sun. Since the Earth has an elliptical orbit, the distance between the Earth and the Sun is not constant in the process of revolving around the Sun, sometimes the Earth is far away from the Sun, and sometimes it is closer to the Sun.

What are genetically modified mosquitoes?
Humans have been suffering from Aedes aegypti mosquitoes and bone pain fever, struggling for many years, many years of effort, we finally saw a ray of light that can inhibit the growth of Aedes aegypti mosquitoes - the release of genetically modified mosquitoes. However, not yet happy, some people say that genetically modified mosquitoes can harm the natural ecology. Look at the positive and negative side of each side of the word, the public can only open their eyes and feel the head, but can not figure it out! In the end, the release of genetically modified mosquitoes is good or bad?

Why did snakes evolve their legs, and is it really more advantageous to walk on their stomachs?
Snakes are one of the coldest killers in nature. They are natural hunting machines. They use spitting letters to analyze chemicals in the air, and they use the ground to sense the vibrations brought by prey and predators. Some snakes even have infrared sensing capabilities. The body temperature of the prey can also be sensed in the absence of light.

Can pets also catch and spread the new coronavirus?
I can't imagine that the new crown pandemic is already in its third year. Since coronaviruses are RNA viruses, they lack the ability to proofread genes when replicating, so they mutate very quickly.
