Senior Olivia Rosenstein balances cross-country competitions with research in quantum gasses and early-universe radio wave signals. Newton’s third law of motion states that for every action, there is an equal and opposite reaction. The basic physics of running involves someone applying a force to the ground in the opposite direction of [...]

NASA is seeking alternative designs for its Mars Sample Return (MSR) mission, which is meant to bring back soil and rocks gathered by the agency’s Perseverance rover. But with the MSR beset by cost hikes and delays, NASA concedes that the current design is “too expensive” and that its aim [...]

Stacking layers of two-dimensional materials on top of each other and varying the twist angle between them massively alters their electronic properties. The trick is to get the twist angle just right, and to know when you’ve done so. Researchers in China have now developed a technique that helps with [...]

Researchers in the US and Canada have detected an effect known as quantum Barkhausen noise for the first time. The effect, which comes about thanks to the cooperative quantum tunnelling of a huge number of magnetic spins, may be the largest macroscopic quantum phenomena yet observed in the laboratory. In the [...]

The US Department of Energy has given the green light for the next stage of the Electron-Ion Collider (EIC). Known as “critical decision 3A”, the move allows officials to purchase “long-lead procurements” such as equipment, services and materials before assembling the collider can begin. The EIC, costing between $1.7bn and $2.8bn, will [...]

A nuclear clock based on thorium-229 is one step closer now that researchers in Germany and Austria have shown that they can put nuclei of the isotope into a low-lying metastable state. The exceptionally low 8 eV excitation energy corresponds to light in the vacuum ultraviolet, which can be generated by [...]

Two photos of a letter from Peter Higgs to Jo Allen dated 1 May 2012
I can’t really claim to have known the Nobel-prize-winning physicist Peter Higgs, but after the sad news emerged last week that he had died on 8 April at the age of 94, I was immediately reminded of my one brush with him. An obituary in the Times described Higgs as “warm, funny [...]
