Curious Kids: Why doesn't the International Space Station run out of air? - The Conversation - ABC Education -

The students of Class 3E from Ferny Grove State School, Brisbane, want to know where the oxygen in the International Space Station comes from, and why don’t they run out of air. An expert in astronomy explains. That’s a really good question. The short answer is the astronauts and cosmonauts (that means a Russian astronaut) bring oxygen from Earth, and they make oxygen by running electricity through water (this is called electrolysis). The air and water on the Space Station all originally came from Earth. But fresh supplies from Earth aren’t enough to sustain the Space Station.

Road Salt Sensor for Better Highway Safety, Less Environmental Damage. Spreading salt on roadways is still the most cost-effective tool for preventing death, injury, and property damage from winter traffic accidents around the world.

Road Salt Sensor for Better Highway Safety, Less Environmental Damage

In 2011, highway departments in the U.S. alone spread 19.6 million tons (1.8 billion kilograms) of salt on icy roads. They pay anywhere from $37 to $130 a ton for rock salt, so the total price tag is in the $1 billion to $2 billion range. But that’s just the beginning of the cost.

What Is Bleach and How Does It Work?

Types of Bleach There are several different types of bleach: Chlorine bleach usually contains sodium hypochlorite.Oxygen bleach contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate or sodium percarbonate.Bleaching powder is calcium hypochlorite. Other bleaching agents include sodium persulfate, sodium perphosphate, sodium persilicate, their ammonium, potassium, and lithium analogs, calcium peroxide, zinc peroxide, sodium peroxide, carbamide peroxide, chlorine dioxide, bromate, and organic peroxides (such as benzoyl peroxide). Does the five second rule really work? In May 2007, scientists at Clemson University in South Carolina decided to find out just how much ick sticks to food as well as to various floor surfaces.

Does the five second rule really work?

By applying a "salmonella soup" to tile, wood and nylon carpet, the researchers were able to not only see how long the germs lived in those environments, but also how many of the micromenaces transferred to slices of bread and bologna.

Teen Scientist Looking for a Covid Cure

Anika Chebrolu, 14, from Texas, has been named America's Top Young Scientist 2020 for finding a compound that could bind to the distinctive spike protein in the SARS-Cov-2 virus and potentially inhibit its ability to infect human cells. Anika is a keen science student and had initially entered the 3M Young Scientist Challenge with a project researching cures for the flu virus, after being ill with the disease. She was named one of 10 finalists for this year’s competition, which meant she could work all summer with the mentor she had been allocated, 3M scientist Dr Mahfuza Ali. Together, they decided to switch the focus of Anika’s research to the Covid-19 virus. (61) L’Oréal-UNESCO For Women in Science Programme 2020 - English version.

Top Jobs For Under 18s - 2020. Equality in science: A mission still not accomplished. Before NASA had computers, they had people, generally women, who performed calculations by hand, or with the aid of slide rules and adding machines. During 1960s-era NASA, mathematical calculation was considered menial, low-status work that was relegated to those who were barred from more prestigious job titles, like ‘engineer’ or ‘physicist’, due to their social status and prejudices at the time. The film Hidden Figures, based on the true story told in the book by Margot Lee Shetterly, follows three ‘human computers’ whose unparalleled mathematical and physical genius made the first American crewed space flights a success.

Our diet can influence the tiny changes in our genome that underlie several diseases, including cancer and obesity. When you look at yourself in the mirror you may ask, ‘How, given that all the cells in my body carry the same DNA, can my organs look so unlike and function so differently?’ With the recent progress in epigenetics, we are beginning to understand. We now know that cells use their genetic material in different ways: genes are switched on and off, resulting in the astonishing level of differentiation within our bodies.

Epigenetics describes the cellular processes that determine whether a certain gene will be transcribed and translated into its corresponding protein. Science and art. Annika Duda What are the links between science and art? There might be more than you think. Science and art have often been perceived as mutually exclusive: scientists are believed to be rigid, logical thinkers, whereas artists are less rational and creative. But these stereotypes can be damaging, especially if students believe they must choose between following the path of arts or sciences. There are many examples, however, of individuals who do not fit this stereotype: Leonardo da Vinci was both a great artist and scientist; theoretical physicist Richard Feynman was also a semi-secret artist; and Albert Einstein – who believed that the greatest scientists were artists as well – was a keen musician.

When science meets art Science and art are complimentary, and graphic designer and computer scientist John Maeda believes that innovation is born when the two subjects come together. When science helps art The act of preserving art is an important science.
