Why don’t we cover the desert with solar panels?

The Sahara Desert receives an abundance of solar energy, raising the possibility of covering it with solar panels to solve global energy problems. However, there are limitations to solar panel efficiency and challenges associated with large-scale solar farms, such as heat absorption and environmental impact. Alternative solutions, such as concentrated solar power plants using giant mirrors, are being explored. Additionally, solar energy can exist on smaller scales, providing a passive source of energy for individual buildings and rural communities.

Vultures The heroes of the ecosystem

The article discusses the importance of vultures as nature’s cleanup crew and the threats they face. Vultures play a crucial role in removing pathogens from the environment, but their populations have declined significantly due to factors such as poisoning from man-made chemicals and habitat loss. Conservation efforts, such as banning harmful drugs and implementing breeding programs, are being made to protect and repopulate vulture communities.

The myth of the boiling frog

The article presents the metaphor of the frog parable to illustrate human behavior towards climate change. It emphasizes the need for immediate action to reduce greenhouse gas emissions and prevent further global warming, highlighting the role of fossil fuels in climate change and the potential consequences of rising temperatures. The article suggests that while transitioning to clean energy sources will take time, efforts to remove carbon from the atmosphere can help mitigate the damage caused by climate change.

The woman who stared at the sun

Hisako Koyama, a Japanese woman with no formal training in astronomy, made remarkable contributions to the study of solar activity. Through her observations and sketches of the sun’s surface, she created one of the most important records of solar activity in human history. Her work allowed scientists to track sunspots and clusters, providing real-time indication of the sun’s magnetic activity and helping predict and plan for volatile solar flares.

What is the coldest thing in the world

Scientists are able to create the coldest materials in the world in physics labs by using laser beams to slow down moving particles. This allows for a better understanding of the inner workings of matter and the development of sensitive instruments, such as atomic clocks and detectors for underground resources. Cold atoms also have the potential to be used in the study of atomic and subatomic phenomena and the detection of gravitational waves.

Why don’t we throw trash in volcanoes?

The article explains why using volcanoes as a solution for waste disposal is not a viable option. It highlights the high cost and impracticality of transporting trash to volcanoes, as well as the risks involved in waiting for eruptions or drilling into magma chambers. The article also discusses the environmental impact and potential dangers associated with using volcanoes for garbage disposal. Ultimately, it concludes that exploring sustainable and less harmful waste disposal methods is necessary.

How did the deepest part of the ocean get so polluted

The Mariana Trench, the deepest part of the ocean, is found to be alarmingly polluted with physical trash and chemicals. Plastics, which are not easily broken down by organisms, and persistent organic pollutants (POPs), including banned chemicals, are contaminating the ocean floor. This pollution not only harms marine life but also poses a threat to human health, as these chemicals can enter the food chain. Moreover, ocean pollution reduces oxygen levels and causes mass death of marine life and reproductive issues for animals. The article highlights the need to address ocean pollution and its consequences.

Why do venomous animals live in warm climates

The article explores the phenomenon of why the most venomous species are found in the warmest places on Earth. It discusses the correlation between global average temperatures and the number of venomous species in each country. The article also explains the functions of venom molecules, the effects of venomous bites, the production of anti-venom, and the role of evolutionary history in the distribution of venomous species.

The bees that eat corpses

The article discusses vulture bees, a species of bees that are unique in their diet of carrion, or dead animals. The study explored the microbiome of vulture bees and found that they have adapted their gut microbes to accommodate their meat-eating diet. This adaptation sheds light on how the microbiome can change in response to changes in diet.
