Companies withhold studies of potential harm from pesticides

One in four industry-funded studies examining the potential harm from pesticides on the developing brain were not shared with EU authorities by the producing companies. This finding raises concern about the reliability of EU safety evaluations of pesticides and undermines trust in the system designed to protect European consumers.

Particles from traffic pollution - the silent killer

It is sunny Monday morning, and I found myself next the busy E4 on the outskirts of Stockholm. How did I end up here? I was asked to write about how analytical chemistry is so much more than just chromatograms in a lab – analytical chemistry is also sampling, testing and putting pieces of a larger puzzle together.

While researching dolphins, SU researchers discover possible new method to improve pharmaceuticals

In the human body, crystals – made of things such as calcium or urea – form masses that can cause pain and serious health conditions, such as gout. Researchers from the Xiaodong Zou group reported a new method to control the growth of ammonium urate crystals - the substance known to cause kidney stones in dolphins.

Physics provides new perspective on cellular function and evolution

Researchers have mapped the physicochemical properties of proteins in 20,000 organisms. The results, published in The Proceedings of the National Academy of Sciences (PNAS), show that the properties not only provide clues to understanding evolution and adaptation, but also add new dimensions to the established taxonomical classification system.

A repressor that monitors the supply of DNA building blocks

Ribonucleotide reductase (RNR) is an essential enzyme that catalyzes the synthesis of DNA building blocks. In a new study from Britt-Marie Sjöberg’s and Pål Stenmark’s groups at DBB, they present several cryo-EM structures and the mechanism of action of NrdR. NrdR is the RNR-specific repressor, that controls transcription of RNR genes in bacteria. The repressor uses an unprecedented nucleotide-sensing oligomerization mechanism to control NrdR-dependent transcription of ribonucleotide reductases.

Harmful Boomerang: PFAS Pollution in Ocean Comes Back to Land

Many of the per- and polyfluoroalkyl substances (PFAS) that end up in the ocean boomerang back to shore after they are re-emitted into air with the crashing of waves, according to a study by researchers at Stockholm University published today in Environmental Science & Technology. The findings suggest that this sea-to-air transport process is a significant contributor to PFAS air pollution in coastal areas.

Scientists show how a salt transporter linked to hypertension and diabetes works

NHA2 is a protein spanning the membrane in kidney and -cells that absorbs salt and its activity is linked with hypertension and diabetes in humans. The transporter-protein exchangers the movement of sodium ions across cell membranes with the movement of protons. Researchers at Stockholm University have now determined what the protein looks like and how the protein adapts to the membrane. These findings shed new light into this important biological mechanism, and provide a basis for structural-based drug discovery.

Water oxidation and clean energy carriers, one step closer

Some 200 years ago, Elizabeth Fulhame, a Scottish chemist, came across the power of catalysts – a material that speeds up a chemical reaction without being consumed during the process. In our day, Stockholm university chemists have been part of a large multinational consortium developing a new hybrid material (metal-hydroxide-organic frameworks, MHOFs) that can use the process of catalysis to speed up the oxygen evolution reaction (OER). This work has just been published in Nature Materials.

The Late Quaternary Chronology of Arctic Ocean Sediments

Icebreaker led expeditions into the central Arctic Ocean have retrieved vast numbers of marine sediment cores that record environmental changes on millennial and orbital timescales. A major obstacle to interpreting these records is to establish accurate age models, a unique challenge in the Arctic where many traditional dating methods do not appear to work.
