Using an approach called DNA origami, scientists at Caltech have developed a technique that could lead to cheaper, reusable biomarker sensors for quickly detecting proteins in bodily fluids, eliminating the need to send samples out to lab centers for testing. "Our work provides a proof-of-concept showing a path to a single-step method that could be used to identify and measure nucleic acids and proteins," says Paul Rothemund (BS '94), a visiting associate at Caltech in computing and mathematical sciences, and computation and neural systems. A paper describing the work recently appeared in the journal Proceedings of the National Academy of Sciences. The lead authors of the paper are former Caltech postdoctoral scholar Byoung-jin Jeon and current graduate student Matteo M. Guareschi, who completed the work in Rothemund's lab.

i was just looking around the rate my professor for caltech… just for fun…

bro why does this fictional character have more ratings than any real faculty 😭 like most of them just have 1 or 2

should i give in to the hype and watch big bang theory???? 🤨

I... a universe of atoms, an atom in the universe.

- Richard Feyneman

Richard Feynman (1918-1988) was an American theoretical physicist who received the Nobel Prize in 1965. Robert Wilson recruited the brilliant young Feynman, only 24 at the time, for the Manhattan Project as a junior physicist soon after completing his Ph.D.  At Los Alamos, Feynman was assigned to the theoretical division of Hans Bethe, and soon became a group leader. Feynman was briefly transferred to the Oak Ridge facility, where he aided engineers in calculating safety procedures for material storage so that inadvertent criticality accidents could be avoided. He was well known for playfully challenging the security at Los Alamos, and was present for the Trinity test in 1945, viewing the explosion through his truck windshield.

After the Manhattan Project, Feynman regretted not reconsidering his work after Germany was defeated in World War II, although he continued to feel that the threat of a nuclear-armed Nazi Germany was enough to justify his initial participation. He turned down an offer from the Institute for Advanced Study and joined Hans Bethe at Cornell from 1945 to 1950, where he taught theoretical physics. Feynman left to join the faculty at Caltech in 1950. There he conducted his groundbreaking research in areas of quantum electrodynamics and superfluidity.

Feynman won his 1965 Nobel Prize in Physics for his work in quantum electrodynamics, a formula well known for its accurate predictions, which combines his path integral formulation and his Feynman diagrams. Additionally, he worked in the fields of the physics of superfluidity and quantum gravity, and developed a model of weak decay. However he caused great controversy when shortly after winning the prize in 1965, he seemingly rejected it. Feynman increasingly felt unease at the award turning the scientists into an institution.

It was no strange thing for Feynman to offer an opinion contrary to authority. Often called a buffoon and a magician, Feynman was scolded by the scientific world for his pursuit of things outside science, like art and music. A series of televised lecturers for the public secured his place in the households of millions in the US and the rest of the world. It was here that his excitement and passion for science trickled into the popular psyche and admitted countless young people into the world of science. He loved science and its limitless possibilities of discovery; it is no surprise, then, that he viewed his Nobel Prize with indifference.

Chemists succeed in upscaling a common reagent for industrial level applications

The metallic element samarium, when bound with other elements, is an incredibly useful chemical reagent for synthesizing molecules that can lead to new pharmaceuticals. Discovered in a Russian mine in 1879, the element was named after the mineral it was found in, called samarskite, which itself was named after Russian mining engineer Vassili Samarsky-Bykhovets. The most common samarium reagent is samarium diiodide, which consists of one atom of samarium and two atoms of the element iodine. But scaling up this versatile reagent to quantities large enough to be used in industrial settings has proved challenging. "The reagent is air sensitive, so you often have to prepare the solution fresh, right before the reaction," says Caltech graduate student Chungkeun Shin, who works in the lab of Sarah Reisman, Bren Professor of Chemistry and the Norman Davidson Leadership Chair of Caltech's Division of Chemistry and Chemical Engineering.
