Hormone cycles shape the structure and function of key memory regions in the brain

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior of our neurons and cognitive processes. Recently, researchers used modern laser microscopy techniques to observe how fluctuations in ovarian hormones shape both the structure and function of neurons in the mouse hippocampus, a brain region crucial for memory formation...

Higher success rate using a simple oral swab test before IVF

Researchers have conducted a clinical study to show how a woman's genetic profile provides information on which hormone treatment is most effective for in vitro fertilization (IVF). The researchers have now developed a simple oral swab test that shows which hormone therapy is the best option for IVF treatment. Read more ›

Remote particle measurement via quantum entanglement

Quantum physics keeps challenging our intuition. Researchers have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough relies on quantum entanglement -- the phenomenon that links particles across distance as if connected by an invisible thread. The discovery opens up exciting prospects for quantum communication and computing, where information becomes accessible only once it is measured. Read more ›

Astrophysicists explore our galaxy's magnetic turbulence in unprecedented detail using a new computer model

Astronomers have developed a groundbreaking computer simulation to explore, in unprecedented detail, magnetism and turbulence in the interstellar medium (ISM) -- the vast ocean of gas and charged particles that lies between stars in the Milky Way Galaxy. The model is the most powerful to date, requiring the computing capability of the SuperMUC-NG supercomputer at the Leibniz Supercomputing Centre in Germany. It directly challenges our understanding of how magnetized turbulence... Read more ›

'Loop'hole: HIV-1 hijacks human immune cells using circular RNAs

Researchers have identified a never-before-seen mechanism that enables HIV-1 to evade the body's natural defenses and use it to support its survival and replication. The 'loophole' is a biological process that involves circular RNAs and marks the first experimental evidence of HIV-1 generating them from an integrated retroviral genome. Findings point to a novel strategy the virus uses to survive, providing a new target in the fight against one of... Read more ›

Butterflies hover differently from other flying organisms, thanks to body pitch

Butterflies' flight trajectories often appear random or chaotic, but their hovering patterns can potentially provide critical design insights for developing micro aerial vehicles with flapping wings. Researchers studied how butterflies use aerodynamic force generation to achieve hovering, using high-speed cameras to observe wild-caught white cabbage butterflies and relying on a deep learning model to track the butterflies' body features and specific wing points during their flight sequences. They found the. Read more ›

New approach to treating aggressive breast cancers shows significant improvement in survival

A new treatment approach significantly improves survival rates for patients with aggressive, inherited breast cancers, according to researchers. In a trial where cancers were treated with chemotherapy followed by a targeted cancer drug before surgery, 100% of patients survived the critical three-year period post-surgery. Read more ›

AI meets the conditions for having free will -- we need to give it a moral compass

AI is advancing at such speed that speculative moral questions, once the province of science fiction, are suddenly real and pressing, says a philosopher and psychology researcher Frank Martela. Martela's latest study finds that generative AI meets all three of the philosophical conditions of free will -- the ability to have goal-directed agency, make genuine choices and to have control over its actions. This development brings us to a critical... Read more ›
