An interdisciplinary team presents a laser-driven technology that enables them to create nanoparticles out of materials such as copper, cobalt and nickel oxides. At the usual printing speed, photoelectrodes are produced in this way, for example, for a wide range of applications such as the generation of green hydrogen.

Recent research has shown that a small chip inserted under the skin can monitor the heart rate and rhythm, and help physicians detect atrial fibrillation in patients who previously experienced what’s called a cryptogenic stroke, one with no identified cause despite thorough patient testing.

Inspired by Chicago’s many nearby bodies of water, a team has developed a way to repeatedly remove and reuse phosphate from polluted waters. The researchers liken the development to a “Swiss Army knife” for pollution remediation as they tailor their membrane to absorb and later release other pollutants.

An international team has discovered a massive cluster of stars of intermediate age in the direction of the Scutum constellation. This object, which has been named Valparaíso 1, lies some seven thousand light years away from the Sun, and contains at least fifteen thousand stars. To detect it, observations have been combined from ESA’s Gaia satellite, and various ground-based telescopes, including the Isaac Newton Telescope at the Roque de los Muchachos Observatory (Garafía, La Palma, Canary Islands).

A research group has demonstrated that the heat generated by the impact of a small astronomical body could enable aqueous alteration and organic solid formation to occur on the surface of an asteroid. They achieved this by first conducting high-velocity impact cratering experiments using an asteroid-like target material and measuring the post-impact heat distribution around the resulting crater. From these results, they then established a rule-of-thumb for maximum temperature and the duration of the heating, and developed a heat conduction model from this.

Scientists have gained the best view yet of the brightest explosions in the universe: A specialised observatory in Namibia has recorded the most energetic radiation and longest gamma-ray afterglow of a so-called gamma-ray burst (GRB) to date. The observations with the High Energy Stereoscopic System (H.E.S.S.) challenge the established idea of how gamma-rays are produced in these colossal stellar explosions which are the birth cries of black holes, as the international team reports.

Engineers report a new type of glue inspired by stubbornly adherent crustaceans, the barnacles. Starting with the fibrous silk protein harvested from silkworms, they were able to replicate key features of barnacle and mussel glue, including protein filaments, chemical crosslinking and iron bonding. The result is a powerful non-toxic glue that sets and works as well underwater as it does in dry conditions and is stronger than most synthetic glue products now on the market.

Physicists have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. They describe how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications.
