FRANKFURT. Most of us find it difficult to grasp the quantum world: According to Heisenberg’s uncertainty principle, it’s like observing a dance without being able to see simultaneously exactly where someone is dancing and how fast they’re moving – you always must choose to focus on one. And yet, this quantum dance is far from chaotic; the dancers follow a strict choreography. In molecules, this strange behavior has another consequence: Even if a molecule should be completely frozen at absolute zero, it never truly comes to rest. The atoms it is made of perform a constant, never-ending quiet dance driven by so-called ...

New research in mice reveals that food-induced anaphylaxis is driven by distinct immune pathways involving inflammatory lipids called leukotrienes. The findings, published across two separate studies, identify genetic and cellular factors that influence susceptibility to severe allergic reactions and point to the potential of the drug Zileuton to block this life-threatening response. Food allergies arise when the immune system mounts an exaggerated response to certain proteins found in foods. This reaction is typically driven by Immunoglobulin E (IgE) antibodies, which recognize dietary allergens and activates mast cells throughout the body. In severe ...

In a Policy Forum, Mateo Aboy and colleagues argue that, instead of turning immediately to rigid regulation to govern emerging quantum technologies, the community should apply a standards-based governance approach tailored to the early, technically focused stage of development. Quantum technologies are poised to revolutionize everything from computing to medicine, offering performance leaps that far surpass the limits of current systems. Yet, this promise comes with complex governance challenges, as these powerful tools ...

AUGUST 7, 2025, NEW YORK – Many major cancers, including those of the lung, breast and prostate gland, spread to the bones as they progress. These bone metastases are often debilitating, even deadly. They are also notoriously resistant to all kinds of treatment, including immunotherapy. Now a Ludwig Cancer Research study has identified in the microenvironment of bone tumors a key architect of that resistance. Researchers co-led by Taha Merghoub and Tao Shi of the Ludwig Collaborative Laboratory at Weill Cornell Medicine with colleagues at Nanjing ...

Adding crushed calcium carbonate — limestone — to agricultural fields can remove tons of carbon dioxide from the atmosphere each year while improving crop yields, a Yale-led study published in Nature Water found. Greenhouse gases in the atmosphere hit a record high in 2024 reaching over 420 parts per million. The U.N. Intergovernmental Panel on Climate Change (IPCC) has identified carbon removal as one key tool in limiting warming to 1.5 C above pre-industrial levels to help mitigate climate change. To reach that target, 15 billion tons of carbon would have to be removed from the atmosphere each year. “There ...
