Showing results for "Media Matters" in Science

What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter? When Democritus stated that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

Although consciousness is at the very center of who we are, its exact nature continues to confound modern science. From where does consciousness originate? At our core, are we material bodies or immaterial conscious minds? Many assume that consciousness is a product of our complex brains, a product of evolution—and yet, there is no evolutionary reason that a mechanical function of the brain should allow us to enjoy the beauty of a sunrise or become intoxicated with the smell of rain on dry earth.

Five times winner of the Publisher Podcast Awards, including Best Technology Podcast, Engineering Matters celebrates the work of engineers who use ingenuity, practicality, science, theory and determination to build a better world. In the UK alone 5.7million people work in engineering related enterprises from manufacturing and agriculture to construction and transportation. Their work ensures that the country has sustainable power supplies, better connectivity between cities, increasing efficiency in production processes; advanced manufacturing methods; and is embracing the digital ...

Christopher Wills's claim has its roots in an insight from Charles Darwin: the interactions between species in an ecosystem are a powerful driver of evolution. In this book Wills describes how, by using the latest genetic techniques, we are probing ecosystems and discovering that even the most apparently barren of them are rich in variety, especially of microbes.

Each day we are exposed to a myriad of natural and human-made chemicals in our food, drinking water, air, soil, at home or at the workplace-pesticide residues, food additives, drugs, household products-but how can we gauge the human health risk posed by these chemicals? Should we believe the somber headlines that depict a serious threat for humans and the environment, or should we follow the reassuring voices of others who claim that the angst is totally unfounded?

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

The Secret Life of Science is a dispatch from the frontlines of modern science. It paints a startling picture of a complex scientific ecosystem that has become the most competitive free-market environment on the planet. It reveals how big this ecosystem really is, what motivates its participants, and who reaps the rewards.

In 2020, COVID-19, the Australia bushfires, and other global threats served as vivid reminders that human and nonhuman fates are increasingly linked. Human use of nonhuman animals contributes to pandemics, climate change, and other global threats which, in turn, contribute to biodiversity loss, ecosystem collapse, and nonhuman suffering.
