Utrecht chemists discover mechanism to design more sustainable molecular catalysts
Utrecht scientists, under the supervision of Marc-Etienne Moret, have discovered a new mechanism to build molecular catalysts. The new mechanism involves the earth-abundant metal nickel instead of precious metals that are often used as part of molecular catalysts. Moret: "This discovery initiates a new area of research that brings about a whole new concept for the design of more sustainable catalysts." In 2017, chemistry researcher Marc-Etienne Moret received an ERC Starting Grant  to study new catalysts with better properties.

New possibilities for botox
PSI researchers have discovered a surprising trick that could expand the possibilities for medical use of botulinun toxin A1, better known under the name Botox, as an active agent. They have developed antibody-like proteins that speed up the enzyme's effect on the transmission of nerve signals. This suggests that Botox might, for example, be able to relief pain more quickly than before.

Digital working in times of crisis
Researchers investigate consensus building in virtual teams during the Covid-19 pandemic Virtual working offers many opportunities, but also harbors risks. In addition to the known disadvantages - less personal contact, communication and coordination difficulties - external crises can pose an additional challenge, especially if employees at different locations work together across local or national borders and are affected to varying degrees by a crisis.

Antibiotic consumption rose massively in the first year of the pandemic
Antibiotic consumption rose massively in the first year of the pandemic
Antibiotics are useless against viruses, including the coronavirus. Nevertheless, doctors in Switzerland prescribed antibacterial drugs about twice as often in the first year of the pandemic as before, report researchers from the University of Basel. A risky practice, warns the research team . It was a time of great uncertainty: when the first coronavirus wave rolled across Switzerland in spring 2020, there were neither diagnostic tests nor a vaccine nor effective medication.

Child and adolescent psychiatry: fewer coercive measures thanks to architectural changes
Child and adolescent psychiatry: fewer coercive measures thanks to architectural changes
Coercive measures are used in psychiatric treatment to avert acute danger to a person's life and health. However, such measures can be associated with considerable risks for patients and treatment teams. It is known from studies in adult psychiatric inpatient wards that environmental factors such as staffing, availability of retreat options, privacy and access to natural light can influence the use of coercive measures.

Set of bacterial genes essential for colonising plant roots
Like humans and animals, plants have a microbiota that shapes their health and thanks to which they assimilate nutrients from the soil. How is this microbiota assembled? Using an innovative approach, scientists at the Max Planck Institute and INRAE have discovered three genes essential for bacteria to colonise plants and live in and on plant roots.

Novel antibiotic substance from the human nose
Researchers at the University of Tübingen have discovered a novel antibiotic substance from the human nose that can be used against pathogenic bacteria. Named epifadin, the molecule is produced from specific strains of the bacterial species Staphylococcus epidermidis , which occur on the mucous membrane of the inside wall of the nose.

Apes remember friends they haven’t seen for decades
Apes recognize photos of groupmates they haven't seen for more than 25 years and respond even more enthusiastically to pictures of their friends, a new study finds. The work, which demonstrates the longest-lasting social memory ever documented outside of humans and underscores how human culture evolved from the common ancestors we share with apes, our closest relatives, was [published today in the journal Proceedings of the National Academy of Sciences .

Rembrandt broke new ground with lead-based impregnation of canvas for The Night Watch
New research has revealed that Rembrandt impregnated the canvas for his famous 1642 militia painting 'The Night Watch' with a lead-containing substance even before applying the first ground layer. Such lead-based impregnation has never before been observed with Rembrandt or his contemporaries. The discovery , published today in Science Advances, underlines Rembrandt's inventive way of working, in which he did not shy away from using new techniques.
