Caesar's Last Breath 23 May, 2025 How many molecules from Caesar’s last breath do we inhale with each breath we take? Shockingly, the answer is about one molecule—we actually do share breaths with Caesar! And, by extension, every breath we take is composed of the previous breaths of everyone who ever lived—Socrates, Lincoln, Einstein, etc. Isn’t that crazy? This is a classic exercise in Fermi estimation—it even has a book named after it. It’s a beautiful introduction to the power of napkin ma

In a new paper published in The Journal of Chemical Theory and Computation, researchers from IBM Quantum® and Lockheed Martin demonstrate how a quantum computer can help accurately model the electronic structure of certain molecules. These so-called, “open-shell” molecules contain one or more unpaired electrons, making them difficult to simulate with classical methods alone. The new research marks the first application of the sample-based quantum diagonalization (SQD) technique to open-shell sy

Forget fingerprints or two factor authentication, scientists may have figured out a way to log into a computer with a synthetic molecule. In the new study published in the Cell Press journal Chem, researchers were able to store and decode an 11-character password encoded in the molecular makeup of a piece of plastic. The technology could help us meet our growing demand for energy-intensive long term data storage, the scientists suggest. “Molecules can store information for very long periods wi

Harnessing the power of qubits is notoriously tricky, though. For example, two of the most common types—superconducting qubits, which are often made of thin aluminum layers, and trapped-ion qubits, which use the energy levels of an ion’s electrons to represent 1s and 0s—must be kept at temperatures approaching absolute zero (–273 °C). Maintaining special refrigerators to keep them cool can be costly and difficult. And while researchers have made significant progress recently, both types of qubit

A species of Paenibacillus bacteria has potent antibacterial activity against some pathogenic bacteria such as Escherichia coli.Credit: Clouds Hill Imaging Ltd/Science Photo Library Researchers have discovered a new antibiotic molecule that targets a broad range of disease-causing bacteria — even strains resistant to commercial drugs — and is not toxic to human cells1. The molecule was found in soil samples collected from a laboratory technician’s garden. The discovery shows that “there is ter

NASA’s Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet. The discovery is one of the most significant findings in the search for evidence of past life on Mars. This is because, on Earth at least, relatively complex, long-chain carbon molecules are involved in biology. These molecules could actually be fragments of fatty acids, which are found in, for example, the membranes surrounding biological cells. Scientists think that, if lif

A team of scientists just discovered the longest organic molecules yet seen on Mars, the fourth planet from the Sun and and a tantalizing venue for humankind’s search for life beyond Earth. Mars today is inhospitable, with significant temperature fluctuations, a thin atmosphere, and an apparent dearth of liquid water on the planet’s surface. But according to new research, published today in Proceedings of the National Academy of Sciences, large molecules found on Mars apparently are as old as l

While the origin of life on Earth is still up for debate, the Miller-Urey hypothesis suggests that a strike of lightning into ocean water mixed with inorganic gases may have triggered the formation of the first organic molecules. Critics of this hypothesis argue that the oceans were—and still are—too vast, and lightning too infrequent, for this explanation to be plausible. New research, however, suggests a solution to these discrepancies: microlightning. Researchers at Stanford University have

Plastics are great, except when it comes to making or disposing of them. Production generally requires the use of chemicals derived from fossil fuels, and so helps to continue our reliance on them. And the final products are generally not biodegradable, so they tend to stick around despite breaking down into ever smaller fragments. Biology might ultimately provide a solution, however. Researchers have identified bacteria that evolved the ability to digest some plastics. And improvements in our

The biological world is awash in chemical signals. Ants lead their nest mates to food with winding trails of pheromones, plants exude aerosols to warn their neighbors of herbivores, and everything you experience as “smell” is a molecule latching onto your nose. Some molecular messages find their targets; most linger unread in the environment. But sometimes, other species — chemical eavesdroppers, bystanders or visitors — can pick up and interpret the signals in their own way. If the message is p
