Australia has already spent more than $100 million dealing with Varroa mite. Here's what we can do next‎

The honeybee mite, Varroa destructor, finally breached Australia's biosecurity defenses four years ago, and is here to stay. Even more concerning, our standard treatments—such as specialized pesticides—are already failing.

Estonian-Swedish grammar challenges established theories‎

A new doctoral thesis from the University of Gothenburg shows that a unique grammatical construction found in Estonia-Swedish dialects contradicts established assumptions about what is possible in Germanic languages.

First quantum biosensor can detect rapid, invisible changes in cells‎

In the development of diseases such as muscular dystrophy, cancer, Ebola and dengue, numerous chemical reactions take place within and between cells that contribute to disease progression. These changes can occur in less than the blink of an eye—within microseconds or faster—making them difficult to analyze. Quantum sensing offers a way to monitor these changes, helping researchers determine when, where and how rapid biological processes occur.

Social inequality can harm the foundations of society‎

Can economic inequality threaten liberal societies? This question lies at the heart of the POLAR project led by Markus Gangl, a sociologist at Goethe University Frankfurt.

Scientists design a clay that can prevent fruits and vegetables from rotting too quickly‎

Avocados from Chile, bananas from Costa Rica, tomatoes from southern Spain, mangoes from Brazil. A large share of the fruit and vegetables we eat have traveled across the globe before they reach store shelves here at home. But many millions of tons are lost every year before they get that far.

What shapes young lives most? Everyday wins, relationships and school outrank crises‎

Which major life events matter to young people? A study by the University of Zurich (UZH) shows that adolescents and young adults primarily cite positive, everyday developmental steps as formative events, for example, school and apprenticeships, friendships, first relationships, travel, and moving out of their parents' home. UZH researchers evaluated open-ended written responses from 1,442 participants in a long-term study. Each participant was surveyed at ages 15, 17, 20 and 24.

Mosquito-borne viruses avoid killing hosts by limiting protein output, study reveals‎

The increase in mosquito-borne virus infections is a growing public health concern. Diseases traditionally confined to tropical or subtropical regions, like dengue or West Nile virus, are expanding their geographic scope. Europe is no longer an exception, and autochthonous infections have already been recorded in Spain.

Leaf-based fluorescence test speeds search for plant gene-editing targets‎

Gene editing of plant DNA has the potential to produce crops with increased performance and resilience, but it can take a long time to achieve these gains. To shorten this process, scientists often use screening tools to determine where and how edits to the plant genome can be most effective.
