InternationalLipids control lethal launch
Our immune system deploys specialized ‘killers’ to tackle viruses or tumor cells. As it turns out, the cellular lipid metabolism plays a key role in controlling these lethal, but essential tasks.

InternationalNew method for controlled crystal growth
Using a short, fast laser pulse, researchers from the United States were able to precisely control the growth of perovskite crystals on gold nanoparticles. The setup (pictured) looks quite intriguing.

InternationalDeep-sea worm is little miss Sunshine
A worm that lives at hydrothermal vents a kilometer under the seasurface tolerates high levels of arsenic and sulfur by turning them into the bright yellow pigment orpiment.

InternationalGripping the green
When talking about better equipment for golf, probably the clubs first come to mind. But as it turns out, also the balls allow all kinds of tweaking. Including a new type of coating that really puts the player’s qualities to the test.

InternationalNasty nematodes
Tiny worms are already causing havoc among beech in North-America. New research shows that also European beech is susceptible to this invasive pest, raising concerns for the health of European forests.

InternationalStress-resistant algae
Plants have a lot to endure. Burning heat, extreme drought, hungry insects, destructive fungi and so on. Researchers in Göttingen have looked at the response to these stress factors in detail from algae and compared them to land plants.
-
InternationalStem cell switch
A single molecular ‘switch’ seems sufficient to activate stem cells. This finding has the potential to significantly improve the efficacy and reliability of cell therapies and bone marrow transplants.

InternationalS(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.
-
InternationalProtective 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.
-
InternationalTiny tin
A spectacular image of an electrocatalyst that exhibits spectacular behaviour. During CO2 reduction, this combination of tin particles on a nanotextured carbon support manages to improve its performance. The secret: particle breakdown.
-
InternationalWell 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.
-
InternationalSoft, lightweight and biocompatible
A US team has developed an organic electrochemical transistor that is highly biocompatible, reports Nature Communications.
-
InternationalTurbocharger 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.
-
InternationalSmall 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.
-
International€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.

InternationalCreating 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.
-
InternationalBiophotonic ‘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.
-
InternationalThe 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.
-
InternationalClumping 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.

InternationalZapping 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.
