Reviews: How Butterflies And Moths Inspire Science

DW Documentary (October 18, 2023) – Butterflies and moths. Graceful and beautiful, they flit about our spring and summer skies. Their delicate choreographies and dazzling colors are among the most amazing in the animal kingdom. But beauty is not their only quality!

Through the lenses of powerful microscopes, scientists discover unexpected secrets about these fragile creatures that can be adapted and applied to make our world better and more sustainable. This film is a journey into the nano-dimensions of butterflies, taking viewers from high-tech labs to dense forests and lavender fields around the world. We take a close look at the iconic morpho butterfly and find out how its iridescent blue wings reveal a way to produce structural color, a discovery which allows researchers to control light.

Physicist Chunlei Guo, whose work involves reproducing butterfly structures, has created a material capable of absorbing all the colors of the spectrum, a discovery that might revolutionize the field of renewable energies. He is also investigating how the amazing hydrophobic properties of butterfly wings could be used to create an unsinkable metal, which could be useful for constructing floating cities if ocean levels continue to rise.

The blue morpho, the industrious silk moth, the transparent glasswing butterfly, the resistant Heliconius, the enigmatic monarch and the delicate white cabbage butterfly – all have inspired discoveries. These have taken place in many different scientific fields, including energy efficiency and medicine — and even in the detection of toxins, thereby helping save lives in the event of chemical or gas attacks. We take a look at the work of researchers, biologists and geneticists.

We also talk to experts, such as physicist and biomimicry expert Serge Berthier, as well as to Jessica Ware, an entomologist at the American Museum of Natural History, about butterflies’ incredible behaviors and capacities. Tiny as they are, butterflies and moths can inspire groundbreaking scientific progress. And they also serve as a warning about what’s at stake if we fail to protect our extraordinary natural environment.

Diet, cooking, and the human microbiome

IN THE LATE 2000s, Rachel Carmody was spending a lot of time counting calories. An anthropology graduate student at Harvard, she was studying whether cooking changed the number of calories the gut can extract from food. When humans invented cooking thousands of years ago, she and her advisor Richard Wrangham wondered, had they opened the door to a new source of energy?

The Brain-Cancer Link

DURING THE past two decades, the number of annual cancer deaths in the United States has fallen by 27 percent, a remarkable improvement driven by new precision diagnoses and treatments tailored to individual patients. Today, oncologists can detect cancer in its earliest stages and deliver drugs that enlist the patient’s own immune system to improve their odds of survival. Yet cancer remains the second deadliest disease in the United States, claiming more than 600,000 lives every year. Its persistence underscores the urgent need for a deeper understanding of how cancer interacts with the body. Assistant professor of neurology Humsa Venkatesh believes she may have found a promising new pathway for highly effective cancer treatments in the most unexpected of places: the human brain.

A cell census provides information on the source of human brain specialization

The brain is composed of multiple regions associated with distinct functions, which have become further specialized in the human lineage. To define how this specialization is implemented, how it arises during development, and how it has emerged over the course of human evolution, a detailed understanding of the cells that make up the human brain is required.

Assyrian Women of Letters

Kanesh Turkey Excavations

4,000-year-old cuneiform tablets illuminate the personal lives of Mesopotamian businesswomen

By DURRIE BOUSCAREN

Excavations at the ancient Anatolian city of Kanesh in Turkey have revealed a district where merchants from the distant Mesopotamian city of Assur in Iraq lived and worked. Some 23,000 cuneiform tablets, mostly dating from about 1900 to 1840 B.C., have been found in the merchants’ personal archives in Kanesh.

The parents of an Assyrian woman named Zizizi were furious. Like many of their neighbors’ children, their daughter had dutifully wed an Assyrian merchant. Sometime around the year 1860 B.C., she had traveled with him to the faraway Anatolian city of Kanesh in modern-day Turkey, where he traded textiles. But her husband passed away and, instead of returning to her family, Zizizi chose to marry a local.

MARILYN HARBERTASHA BALAKRISHNAN

Orbital debris has been a looming issue for decades, and it’s only getting worse as activities in space increase. With technical expertise and authority over space activities widely distributed across the US government, officials need to determine the appropriate regulations and policies to address how space is changing.

The risks of radioactive waste water release

The wastewater releas e from the Fukushima Daiichi nuclear plant is expected to have negligible effects on people and the ocean

In 2011, the east coast of Japan suffered an earthquake and tsunami that resulted in the meltdown of three of the reactors at the Fukushima Daiichi nuclear plant. This led to an uncontrolled release of large amounts of radioactive material to the surrounding land and to the Pacific Ocean. 

Dating the arrival of humans in the Americas

A debate about the age of ancient footprints continues

Dating the oldest evidence for the presence of Homo sapiens in the Americas is a matter of ongoing debate. One view is that the earliest such evidence is from 16,000 to 14,000 years ago, after the Last Glacial Maximum (LGM), when people would have crossed the Beringian strait from Siberia over a dry land bridge.
