For more than 80 years, scientists around the world have been searching for neutrinos—tiny but elusive subatomic particles with zero electric charge. These particles may hold the secrets to the nature of anti-matter and tell us what the universe was like just seconds after the Big Bang – if we can find them. Trillions of these ghostly particles pass through our bodies every second, but they are so pathologically “shy” that neutrino hunters have to use Olympic-size pools deep underground and a gigantic cube of Antarctic ice to catch just a few.
In this podcast, renowned astrophysicist Ray Jayawardhana takes us on a thrilling journey into the world of neutrinos and the colorful lives of those who chase them, as discussed in his new book “Neutrino Hunters: The Thrilling Case for a Ghostly Particle to Unlock the Secrets of the Universe.”
Inspired by The Power of Poison, this year’s Origami Tree features a collection of nearly 800 wicked, wild, and wonderful origami models, including this cobra.
Fun fact: doctors are testing the venom of the India monocellate cobra (Naja kaouthia) for use against arthritis. It has been used as a traditional remedy against the ailment for thousands of years.

Among the Museum library’s rare books is a silk-covered album containing over 100 beautiful hand-painted butterflies on a dozen plates produced sometime between 1830 and 1871.
A fine example of Chinese trade art intended for Western consumption, the book is important for two reasons.

Name: Hemlock (Conium maculatum)
Also Known As: Poison Hemlock, Devil’s Bread, Beaver Poison, or Poison Parsley
Found in: Europe, North Africa, and Asia. Hemlock grows near streams and pools of standing water, especially along the borders of pastures and cropland.
This toxin disrupts messages between the nervous system and the muscles, causing “ascending muscular paralysis.” Within hours after consumption the heartbeat slows, and paralysis begins in the lower legs, moving up to the waist and lungs. The mind remains alert until death is very near.
Poison Plus: In 339 BC, after being accused of corrupting young Athenians with his radical ideas, the philosopher Socrates was sentenced to the death penalty—a cupful of poison hemlock.

These flower-like anemones are no shrinking violets—they’re deadly predators. Without the ability to see or swim, they rely on their poisonous tentacles to snare prey. (Don’t worry, clownfish have a special adaptation—a thick layer of mucus—that protects them from the anemone’s poison).
And, as it happens, venoms from various anemone species are currently being studied for potential uses to treat cancer (Entacmaea quadricolor), obesity, and multiple sclerosis (Stichodactyla helianthus).
