Borexino spots solar neutrinos from elusive fusion cycle

Neutrinos produced by the elusive carbon–nitrogen–oxygen (CNO) cycle in the Sun have been observed for the first time – confirming a theory first proposed over 80 years ago. The observation was made by physicists working on Italy’s Borexino detector and provides an important insight into how stars power themselves by converting hydrogen into helium.

Gold nanotubes and infrared light could treat asbestos-related cancer

Gold nanotubes can destroy cancer cells, according to physicists and medical researchers at the University of Cambridge and the University of Leeds. They found that their nanotubes, which were tuned to have strong near-infrared absorption, can enter mesothelioma cells and destroy them when heated with laser light.

Microtube implosions could produce megatesla magnetic fields

A newly-discovered mechanism known as microtube implosion could make it possible to generate magnetic fields 1000 times stronger than any yet seen in the laboratory. According to the researchers who developed it at Japan’s Osaka University, the new method could be used to generate super-strong magnetic fields for fundamental research in fields such as materials science, quantum electrodynamics and astrophysics.

Black phosphorus composite makes a better battery

A new electrode material could make it possible to construct lithium-ion batteries with a high charging rate and storage capacity. If scaled up, the anode material developed by researchers at the University of Science and Technology of China (USTC) and colleagues in the US might be used to manufacture batteries with an energy density of more than 350 Watt-hours per kilogram – enough for a typical electric vehicle (EV) to travel 600 miles on a single charge.

Honey flows faster than water in specially coated capillary tubes

Honey and other highly viscous fluids can flow faster than water in specially coated capillary tubes. This surprising discovery was made by Maja Vuckovac and colleagues at Finland’s Aalto University who also show that the counterintuitive effect stems from suppressed internal flows within more viscous droplets. Their results directly contradict current theoretical models of how liquids flow in superhydrophobic capillaries.
