InternationalNatural and unnatural amino acids show synthetic synergy
A team from Groningen and Barcelona cleared up what takes place when you put a designer enzyme with unnatural amino acids through a directed evolution campaign, as shown in ACS Catalysis. ‘We didn’t anticipate this at all.’

InternationalTicks owe their tenacity to glycine-rich proteins
Thanks to colloid chemistry, ticks can suck our blood at their leisure. By chance, two groups from Maastricht and Wageningen were the first to shed light on this, as they report in Nature Chemistry.

InternationalAn X-ray lens on catalysts
Researchers in Ghent have found a method to determine the temperature of a catalyst very locally during a reaction, as reported in Nature Catalysis. Their work offers a new fundamental view of catalytic reactions.

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.

InternationalDrug probe fishes for off-targets
Attaching a biotin tail to a cancer drug makes it possible to see very specifically which proteins the drug targets in lysed cancer cells, as a Dutch team shows in ChemBioChem.

InternationalWashing your laundry in hydrochloric acid
Researchers in Amsterdam, together with technology company Avantium, have developed a process to extract glucose from polycotton and recycle the remaining polyester. It is already working on a pilot scale, Nature Communications reports.

InternationalStereospecific superglue
Simple molecules can be used to make a biodegradable glue that is stronger than current petroleum-based mass products. And it does not have to be much more expensive, write US researchers in Science.

InternationalEphemeral active sites form super acid
Research into plastic recycling with sulphated zirconium oxide took an interesting fundamental turn when a team of Dutch and American chemists found signs of transient superacidity, as reported in Angewandte Chemie International Edition.
