EnglishS(tea)ping against metals
Some cultures serve a cup of tea with every meal. Recently, researchers at Northwestern University discovered that tea can filter out some of the heavy metals. As well as being tasty, a cup of tea now seems to have another small health benefit.

EnglishProtective bubbles
Fatty tissue is an important energy reserve. But it also acts as a super-strength protective ‘bubble wrap’ for fragile parts of the skeleton.

EnglishWell marinated
Single-cell techniques offer many possibilities, but it is difficult to reach all the cells inside organs. Researchers at MIT have developed a new approach that brings those hard-to-reach parts into brilliant focus.

EnglishSoft, lightweight and biocompatible
A US team has developed an organic electrochemical transistor that is highly biocompatible, reports Nature Communications.

EnglishTurbocharger for photosynthesis
Hornwort, a moss, is capable of highly efficient photosynthesis thanks to a ‘turbocharger’ that allows this tiny plant to concentrate CO2 in its cells.

EnglishSmall variations, serious consequences
Genetic variants of the BIM protein increase therapy resistance in leukaemia cells, researchers in Singapore show. Important findings for East Asian populations, where these variants are relatively common.

English€5 million for better imaging
Amsterdam-based Confocal.nl has received a €5 million investment to make its live cell imaging more accessible. As a foretaste of what is possible, they have produced this stunning image of a mouse ear.

EnglishCreating colours
Colour is an intriguing phenomenon, as it is truly in the eye of the beholder. To create that sensation of colour, nanometer-scale particles need to be structured in just the right way.

EnglishBiophotonic ‘windows’ enable symbiosis
Several molluscs have developed benificial relationships with symbiotic, photosynthetic algae. Heart cockles boast advanced biophotonic structures in their shells that operate like optic fiber cables to catch and transmit the incoming sunlight.

EnglishThe symmetry of bees lies within
Nature is full of symmetry, though often only on the outside, but recently an international team discovered that honeybees also build the inside of their nests symmetrically. As well as being aesthetically pleasing, this has practical advantages.

EnglishClumping pests
A team from Umeå University in Sweden has been studying how bacteria pass on their resistance genes to each other, resulting in a beautiful picture.

EnglishZapping sand
Turning soft beaches into hard rock. American researchers managed this (at least on lab scale) by exposing sea-soaked sand to a mild electric current.

EnglishSmart intruders
By studying the infection of lung organoids, Swiss researchers revealed how a notorious pathogen deploys a Trojan horse-stategy.

EnglishOrganic synthesis goes golden
Working with dyes is asking for pretty pictures. While synthesising fluorescent tracers, Maarten van Meerbeek took this picture of a Cy5 dye.

EnglishNecessary neurons
Noses are as diverse as the species they belong to. Ants use antennae to detect and process olfactory signals. But without the Orco protein, the development of the required neurons is halted.
-
EnglishFood fight
Harmful bacteria? Don’t be too quick to judge, because sometimes toxins can also be protective.
-
EnglishHey Google, what does a brain look like?
A team from Google Research and Harvard University has published the largest ever dataset of neural connections in a fragment of the human brain.

EnglishDNA diamonds
You can create extraordinary photonic crystals out of ‘tetrapods’ using DNA origami with unprecedented precision.
-
EnglishSensitive channels
Surprisingly little is known about the molecular basis of our sense of touch. A newly discovered ion channel fills in the picture.
