Zwitterions make medical implants safer for patients

New coating material inhibits the build-up of proteins, reducing risk of blood clots

Photo showing a person's gloved hand using a pair of tweezers to hold a square of transparent material. Below the material is a beaker full of what looks like blood, but is actually water containing red food dye. The material looks to have been recently dipped in the dye, and the dye has clung to a spiral pattern "painted" onto the material with a zwitterionic coating. In the background are various objects indicating that this is happening in a laboratory.

Solar cell greenhouse accelerates plant growth

A greenhouse with a perovskite solar cell rooftop led to faster growth and larger leaves in radicchio seedlings

Radicchio seedlings grown under glass and perovskite rooftops

AI speeds up detection of neutron star mergers

New approach could aid “multimessenger” astronomy by quickly locating sources of gravitational waves emitted during these cosmic events

Artist's impression of the gravitational wave and electromagnetic radiation signals from a distant binary neutron star merger arriving at Earth. The image shows the Earth floating in space with a telescope hovering above it in the bottom left corner, while in the top right corner a pair of bright spots are emitting ghostly blue waves

Radioactive gold nanoparticles could track drug distribution in the body

Activation imaging using neutron-irradiated gold nanoparticles enables visualization of drug distribution in mice for several days after injection

Brillouin microscopy speeds up by a factor of 1000

The technique can now be used to image viscoelastic properties of biological samples much more quickly and safely, at high resolution

An artist's representation of the new Brillouin microscopy approach that allows entire light-sheets to interact with 3D biological samples. The artwork features neon-green sheets of light and zigzag oscillations (representing waves) intersecting purple blobs decorated with cartoon-style vibration lines (representing phonons), all against a blue background

Electron and proton FLASH deliver similar skin-sparing in radiotherapy of mice

Comparison of electron- and proton-based FLASH radiotherapy reveals remarkable similarity in reducing acute skin damage

Sterile neutrinos are a no-show (again)

Hypothetical fourth neutrino flavour is absent from new data from Fermilab's NOvA experiment

Graph showing a neutral current interaction in the NOvA Far Detector

Atomic anomaly explained without recourse to hypothetical ‘dark force’

Effect observed in 2020 arises from changes in nuclear structure, not new physics

Composite image showing photos of PTB's ion traps and the PENTATRAP Penning trap mass spectrometer at MPIK in Heidelberg superimposed over a grid of blue, black and pink squares labelled with the name and mass number of different isotopes. Some of the black squares are raised, and these are the ytterbium isotopes the team studied

The enigma of Trappist-1 b: a thick atmosphere or airless rock?

Thermal emission measurements from the exoplanet Trappist-1 b suggest two plausible yet contradictory scenarios

Artistic impression of the exoplanet Trappist-1 b

Novel zinc alloys could make bone screws biodegradable

New coarser-grained alloys are strong enough to challenge stainless steel and titanium as materials for orthopaedic implants, say researchers

Photo of Feng Nei in the lab with his zinc alloy prototype. He's wearing glasses and a white lab coat and holding the prototype with metal tweezers, and is slightly out of focus so the emphasis is on the prototype, which is in focus. A rack of blue-lidded chemical bottles is on a shelf in the background.
