Caltech

Scientists from Caltech and WHOI have found evidence that Earth’s core is leaking. High levels of a particular isotope of helium were found in lava flows in Canada, which the team proposes originated in the planet’s core.

On the largest scales possible, the universe resembles a web of light spun by an inconceivably large spider. Now, astronomers have detected very faint light from these cosmic web filaments in the deep, dark, distant universe.

Caltech scientists have developed a new hybrid vaccine that combines mRNA and protein nanoparticles. In mouse tests, the prototype produced five times more antibodies than existing COVID-19 vaccines, and could be used against a range of diseases.

The ingredients in stars are usually pretty evenly mixed throughout, but now astronomers have discovered a bizarre star with two distinct faces, each made of a different element, which defies explanation.

The very fabric of spacetime is constantly warping on unimaginably tiny scales, as ripples from past cataclysms wash over us. Astrophysicists have now detected a background sea of gravitational waves, using a galaxy-scale detector of dead stars.

Robots often struggle to adapt to changing conditions. Now engineers at Caltech have designed a new robot that can roll around on four wheels, flip them into rotors to fly, or transform for six other types of motion.

Scientists have created models of human embryos by programming stem cells. The models give a glimpse into a key stage of development that can reveal new insights into genetic disorders and preventing failure in early pregnancy.

Researchers have developed a wearable, noninvasive sensor that monitors for a biomarker of inflammation in the wearer’s sweat. They say the device could be used at home by people with chronic inflammatory diseases.

Gravity is the only fundamental force that can’t currently be explained by quantum physics. Now scientists have outlined a plan to look for signs of quantum gravity out in the cosmos by listening in to the 'ringing' of colliding black holes.

A Caltech team is celebrating the world's first space-based wireless power transmission, and the first time detectable levels of power have been beamed down to Earth. The Space Solar Power Project aims to unlock huge orbital clean energy resources.

Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity.

Astronomers have witnessed an apocalypse from across the galaxy, as a planet crashed into its star. It’s an event long assumed to happen in many star systems – including our own someday – but this is the first time it’s ever been seen directly.
