About The Study: The results of this randomized clinical trial suggest that while over-the-counter (OTC) and OTC+ (audiologists provided limited services for OTC hearing aids) service models were effective, they did not achieve the same outcomes as the audiologists fitted prescription hearing aids following best practices service model. As high-end and low-end hearing aids yielded similar outcomes, support for the higher cost of high-end hearing aids was not identified for individuals with mild ...

Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19th and early 20th centuries. With its discovery, scientists began to understand how small, self-produced organic molecules could influence physiological processes in plants such as growth, cell division, flowering, fruit ripening, and stress responses. The auxin family of phytohormones promotes cell elongation and root development and is involved in directional growth, such as growing toward light. It works by moving directionally within plant tissues to establish concentration ...

Many an orange cat-affiliated human will vouch for their cat’s, let’s say, specialness. But now scientists have confirmed that there is, in fact, something unique about ginger-hued domestic felines. In a new study, Stanford Medicine researchers have discovered the long-posited but elusive genetic mutation that makes orange cats orange — and it appears to occur in no other mammal. The finding adds to our understanding of how subtle genetic changes give rise to new traits, the researchers said. Lots of mammals come in shades of orange — think tigers, ...

At its heart, this research uncovers the hidden geometric principles behind the unique shape of rose petals. While scientists extensively studied shape morphing in natural sheets such as leaves and petals, the team at Hebrew University discovered a new player: MCP incompatibility—a geometric principle that causes the petal’s signature cusps. It turns out that as the petal grows, stress builds at the edges, shaping the curves we recognize and love. The discovery not only uncovered the geometric origin of the shape of rose petals, but also introduces a new paradigm for ...

A new study shows that highlighting shared values and common goals can significantly increase the acceptance of civic organizations that are often seen as controversial and delegitimized for challenging the status quo. The research tested different messaging strategies on more than 1,600 Jewish Israeli participants, using real-world examples from a delegitimized prominent NGO. Messages that focused on widely supported activities—like providing services to marginalized communities—or that framed the organization as part of a shared value-based identity led to greater perceived legitimacy. The findings offer a practical ...

South African study identifies two new breast cancer genes in black women   Genetic factors contribute to some 30% of breast cancer cases in SA, necessitating investment in genomic research in African contexts.   A seminal genetic study published in Nature Communication has discovered two genetic variants linked to breast cancer in black South African women, deepening knowledge about the genetic basis for this disease in African populations. The genome-wide association study (GWAS) of breast cancer is the first to have been done in African women living on the continent. A GWAS is a powerful ...

A new, incision-free technique developed at UVA Health to treat debilitating brain lesions called cerebral cavernous malformations, or cavernomas, has shown great promise in early testing, halting the growth of the lesions almost entirely. The new approach could represent a paradigm shift in how the malformations, commonly called CCMs, are treated, the researchers say. The technique uses tiny, gas-filled “microbubbles” propelled by focused sound waves to open the brain’s protective barrier and stunt the growth of the malformations. “This is a clear example ...

Prevention and treatment campaigns are not adequately targeting the particular needs of the 50+ years age group. Indeed, between 2000 and 2016, the number of adults aged 50 years and older living with HIV in sub-Saharan Africa doubled. At present, their HIV prevalence is exceeding that of younger adults. By 2040, one-quarter of people living with HIV in Africa will be aged 50 years and older; tailored awareness and treatment campaigns are pressing. Dr Luicer Olubayo, a researcher at the Sydney Brenner ...

There is always a need for a refrigerant with a large ΔH at operating temperature. On the other hand, refrigeration equipment generally available typically functions near/below RT. Thus, for ferroelectric refrigeration to be practical, a large ΔH at a transition near/below RT is essential. Representative PST ceramics demonstrate substantial promise for EC refrigeration near RT, attracting considerable interest. The highly ordered PST ceramic always has excellent EC properties, while it is difficult to achieve. Previous researchers often employed a heat treatment process combining high-temperature quenching and long-term annealing to obtain highly ...

New research uncovers the strongest solar event ever detected — rewriting our understanding of space weather and radiocarbon dating. An international team of scientists has discovered an extreme spike in radiocarbon corresponding to the year 12350 BC during the dusk of the last Ice Age. However, the strength of the event could not be assessed earlier because of the lack of an appropriate model. Presently, it has been identified as the most powerful solar particle storm known to date – a colossal ...
