Dark matter, an elusive and invisible substance, constitutes a significant portion of the universe's mass, detectable only through its gravitational effects. First proposed by Fritz Zwicky in the 1930s and supported by Vera Rubin's observations in the 1970s, dark matter does not interact with light, making it invisible. Scientists explore its nature through various theoretical candidates like WIMPs, axions, and sterile neutrinos. While detection remains challenging, methods include underground labs, particle accelerators, and indirect observations. Ongoing research promises to unravel this ...

Here for the first time, in rich human, political, and scientific detail, is the complete story of how the bomb was developed, from the turn-of-the-century discovery of the vast energy locked inside the atom to the dropping of the first bombs on Japan. Few great discoveries have evolved so swiftly - or have been so misunderstood. From the theoretical discussions of nuclear energy to the bright glare of Trinity, there was a span of hardly more than 25 years.

Ed Dwight: A Trailblazer's Journey from Astronaut Trainee to Space Traveler Edward Joseph Dwight Jr., commonly known as Ed Dwight, was born on September 9, 1933, in Kansas City, Kansas, during an era marked by deeply entrenched racial segregation and widespread discrimination against African Americans.

Dwight's father, Ed Dwight Sr.,...

There is nothing more essential to our health and well-being than breathing. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices.

The remarkable stories of the world's most famous body parts. All too often, historical figures feel distant and abstract; more myth and legend than real flesh and blood. These stories of bodies and its parts remind us that history's most-loved, and most-hated, were real breathing creatures who inhabited organs and limbs just like us - until they're cut off that is. Medical historian Dr Suzie Edge investigates over 40 cases of how we've used, abused, dug up, displayed, experimented on, and worshipped body parts.

It takes tremendous biological creativity to be a plant. To survive and thrive while rooted in a single spot, plants have adapted ingenious methods of survival. In recent years, scientists have learned about their ability to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit, to name just a few remarkable talents.

Yet the full story of what happened, and why, has never been told.

The Earth teems with sights and textures, sounds and vibrations, smells and tastes, electric and magnetic fields. But every kind of animal, including humans, is enclosed within its own unique sensory bubble, perceiving but a tiny sliver of our immense world. In An Immense World, Ed Yong coaxes us beyond the confines of our own senses, allowing us to perceive the skeins of scent, waves of electromagnetism, and pulses of pressure that surround us.
