Secrets of the Pyramids

The technical knowledge of Egyptian architects once again exceeds expectations. Was Egypt’s oldest pyramid, the Step Pyramid of Djoser, built using some seriously high-tech kit? And what’s with the huge, unexplained cavity that’s been discovered in the Great Pyramid of Giza?

Living fossils

Meet the creatures for whom time has almost stood still. These animals give us a glimpse into what life was like millions of years ago, and show us just how resilient some groups have been to the calamitous events that have consigned others – such as the dinosaurs – to extinction.

A mysterious UFO

There’s a mysterious object hurtling at one million miles per hour across the Milky Way. It’s moving so fast that it could exit the Milky Way entirely – and scientists are still trying to figure out what it is. Not quite a planet and not quite a star, so what is it?

Proba-3

The Proba-3 mission aims to unravel the mysteries of the Sun’s atmosphere by creating artificial eclipses on demand. But achieving this feat means teaching two spacecraft to perform a complicated dance with an unprecedented level of precision. If the mission is successful, scientists will be able to study the Sun’s corona in unprecedented detail, ushering in a new era for space observation.

Science: What Is It That Makes Humans Unique?

DW Documentary (September 14, 2024): What made our ancestors evolve in such an extraordinary way? This film presents the latest scientific theories on how the human species evolved and looks at the shadow side of our unique abilities.

Some animals see, hear or smell better than humans. Others can find their way in the dark much better than we can. Some can fly. All animals communicate, some have excellent memories and others build complex structures and have highly-developed social skills. So what sets humans apart? Why have humans evolved such highly developed cognitive abilities in comparison to animals?

The documentary sheds light on this major question of human evolution — one of the mysteries that has long puzzled the world of science. What is it that makes humans so fundamentally different from other animal species? And will our extraordinary abilities ultimately lead us to self-destruction?

Moondance

Experience the marvel that is night-blooming tobacco By Leigh Ann Henion

In western North Carolina, the mountain growing season is short, and autumn is already tossing yellow-and-red confetti against my windshield as I drive the back roads to my friend Amy’s homestead. Curve after curve, I find locust trees that are a few shades lighter than they were last week. Buckeyes also seem well on their way to change. It is now hard to tell the difference between orange leaves falling and monarch butterfly wings rising. The signs of summer and fall, all intertwining.

What If Fungi Win?

Arturo Casadevall Johns Hopkins Univ. Press (2024)

Earth’s largest organism, the ‘Humongous Fungus’, thrives under the floor of Malheur National Forest in Oregon. Sprung from a tiny spore 8,000 years ago, it weighs an estimated 31,500 tonnes spread over 10 square kilometres, sucking in nutrients from trees. Fungi are regarded as being more closely related to animals than to plants. “Fungi and humans share nearly 50% of their DNA,” observes epidemiologist Arturo Casadevall, in his brilliant book exploring the properties of fungi that are both fruitful and deadly to humans.

Possible: Ways To Net Zero

Chris Goodall Profile (2024)

Net-zero carbon emissions by 2050 are the global goal. China leads the world in installing wind- and solar-energy capacity, comments businessperson and environmental writer Chris Goodall, in this realistic but hopeful analysis of the technological and attitudinal challenges that all nations face in achieving net zero. The UK laundry company Oxwash — founded in 2018 by a university student tired of broken washing machines — provides services fuelled by renewable electrical power and gas from anaerobic digesters of farm waste.

Human Rights: The Case For The Defence

Shami Chakrabarti Allen Lane (2024)

International agreements on fundamental human rights, such as entitlement to a fair trial and free speech, are now under threat in Europe, the United States and elsewhere. Shami Chakrabarti, a human-rights lawyer and former director of the UK National Council for Civil Liberties, considers how to defend these rights. How can “global inequality, conflict, climate catastrophe and the new and under-governed continent of the Internet” be tackled without global values and higher laws, or ways to enforce them?

One Step Sideways, Three Steps Forwards: One Woman’s Path to Becoming A Biologist

Rosemary Grant Princeton Univ. Press (2024)

A scientific life “requires critical thinking, following exceptions to your pet theory, respect for others and strong ethical values”, concludes evolutionary biologist Rosemary Grant. Her memoir tells of a girl fascinated by birds and fossils, who later formed a celebrated team with her biologist husband Peter. While raising a family, the couple studied Darwin’s finches in the Galapagos Islands, Ecuador, for six months each year from 1973 to 2012. They revealed visible natural selection in a bird’s lifetime — contrary to Charles Darwin’s initial thinking.

The Occasional Human Sacrifice: Medical Experimentation and the Price of Saying No

Carl Elliott W. W. Norton (2024)

Bioethicist Carl Elliott’s analysis of medical malpractice begins grippingly: “Let me present my credentials as a coward.” He then lists the times he failed to object to mistreatments as a medical student, followed by his frustrating campaign to publicize a case of suicide at his university in which a psychiatrist enrolled a patient in a dubious drug study. These experiences illuminate six historical cases of “occasional human sacrifice” caused by people’s alleged consent to participate in programmes that they did not comprehend.

Learning from a climate disaster: The catastrophic floods in southern Brazil

The catastrophic floods that affected southern Brazil last May should serve as a warning to human societies that, despite the still widespread climate change skepticism or denial, mitigation and adaptation to cope with the ongoing climate crisis are urgently needed. The toll was 213 people killed or missing; 2.4 million people affected, including 600,000 displaced; and unprecedented losses in urban and rural infrastructure, including livestock.
