Pushing the right buttons: Fern guides its embryo's sense of up and down‎

Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with words, but through pressure. By applying force at precisely the right locations, a fern tells its embryo what is up and what is down, and therefore where roots and leaves should develop. This phenomenon was discovered by Ph.D. candidate Sjoerd Woudenberg in his research on the fern Ceratopteris richardii. He defended his doctoral thesis at Wageningen University & Research.

In Tampa, storm-weary residents detail the costs of extreme weather‎

An Ybor business owner closed her yoga studio repeatedly from worries over moldy, waterlogged walls. A Pinellas woman's home flooded in one hurricane, and a tree crushed her car in another. A Tampa student feared her insulin would become ineffective in extreme, hot temperatures.

Linguist explains how AI makes fake news more credible‎

Fake news generated by AI is often perceived as more credible than texts written by humans. That worries linguist Silje Susanne Alvestad. In 2017, "fake news" was chosen as the new word of the year by the Language Council of Norway. But what are the linguistic features of fake news, and can fake news be uncovered on the basis of linguistic traits? Linguist Silje Susanne Alvestad has examined this in the project "Fakespeak—the language of fake news." She and her research colleagues have investigated the language of fake news in English, Russian and Norwegian.

Australia's happiness crisis could cost us our global mojo‎

Along with cricket, thongs and backyard barbecues, the arrival of the annual Australian Lamb ad has become synonymous with an Australian summer. What began back in 2005 as a pitch to get Australians eating more lamb has since become a yearly cultural icon that tackles an issue that resonates with the moment—from border closures during COVID to the generation gap.

A rethink is needed on zero-tolerance school behavior policies‎

Persistent concerns about poor behavior in UK secondary schools have led to the widespread implementation of disciplinary behavior management strategies. These include the use of isolation rooms, where children are sent to work alone.

The term 'resilience' becoming a burden for women in agriculture, study shows‎

New research from Adelaide University is questioning the widespread use of the term "resilience" in Australian agriculture, arguing that its overuse can place unfair pressure on individual farmers and obscure the need for systemic support. Published in the Journal of Rural Studies, the study explores the perspectives of women involved in farming businesses across Australia, examining how resilience is understood, experienced, and talked about within the sector.

Aging hens may lay fewer eggs as gut health declines, study finds‎

In an era of rising grocery costs, eggs remain one of the most accessible and complete protein sources for families. New research from the University of Hawai'i at Mānoa's College of Tropical Agriculture and Human Resilience (CTAHR) is investigating how chickens age to help keep that high-quality protein on dinner tables.

What is a 'seesaw protein' that switches functions by changing shape?‎

Inspired by the simple mechanism of a seesaw—when one side goes up, the other side goes down—researchers asked an intriguing question: Could a single molecule switch between two different roles like a seesaw? This idea led to the creation of a new type of artificial protein called the "seesaw protein."

How do clouds form in Antarctica? The first flight-based aerosol measurements in 20 years‎

Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how clouds actually form in Antarctica, how they interact with the atmosphere and what role aerosols play in this process has not been sufficiently researched to date. Engaging in the SANAT flight campaign, the Alfred Wegener Institute, the Leibniz Institute for Tropospheric Research and the Max Planck Institute for Chemistry aim to help close this knowledge gap. The flight-based aerosol measurements conducted in Antarctica are the first of their kind in 20 years and also the first to extend deep into the interior.
