Atacama surprise: The world’s driest desert is teeming with hidden life

New research reveals that life beneath the surface of one of the driest places on Earth is far more resilient and diverse than many scientists expected. An international team led by the University of Cologne studied tiny soil worms known as nematodes in Chile’s Atacama Desert. Often compared to polar…

ChatGPT as a therapist? New study reveals serious ethical risks

As more people seek mental health advice from ChatGPT and other large language models (LLMs), new research suggests these AI chatbots may not be ready for that role. The study found that even when instructed to use established psychotherapy approaches, the systems consistently fail to meet professional ethics standards set…

Wireless retinal implant helps blind patients see again

A tiny wireless retinal implant has helped restore central vision in people with advanced age-related macular degeneration (AMD), according to results published in the New England Journal of Medicine. Advanced atrophic AMD, also called geographic atrophy (GA), is the most common cause of permanent blindness in older adults and affects…

Turisti in crociera, studenti in gita, connazionali in vacanza: centinaia gli italiani bloccati a Dubai – Notizie – Ansa.it

Nessun rischio sulla incolumità degli italiani, molti studenti, rimasti bloccati a Dubai, ma “preoccupazione per l’alto numero” delle persone presenti negli Emirati Arabi e che devono rientrare in Italia. Il ministro degli Esteri, Antonio Tajani, non nasconde la complessità della situazione che riguarda i tantissimi connazionali presenti nell’area del conflitto.…

In diretta dallo studio di via della Dataria a Roma, Grosso risponderà alle domande del direttore Luigi Contu e dei giornalisti della redazione delle Cronache italiane.     L’evento…

Scientists reveal why a popular anti-aging compound may also fuel cancer

Polyamines are naturally produced molecules present in all living cells. They play a vital role in basic biological functions, including cell growth and specialization. In recent years, scientists have focused on these compounds, especially spermidine, for their potential to support healthy aging. Often described as ‘geroprotectors,’ they have been shown…

Ex Ilva di Taranto, muore un operaio precipitato nel vuoto – Notizie – Ansa.it

Un operaio della ditta di pulizie Gea Power dell’indotto ex Ilva, Loris Costantino, 26 anni, è morto dopo essere caduto da un piano di calpestio nel reparto Agglomerato dello siderurgico di Taranto, da un’altezza di una decina di metri.

Hidden oceans on icy moons may be boiling beneath the surface

The outer planets are surrounded by dozens of moons locked in thick shells of ice. Some of these frozen worlds, including Saturn’s moon Enceladus, are believed to contain vast oceans of liquid water trapped between their icy crust and rocky interiors. Because liquid water is essential for life as we…

A tiny twist creates giant magnetic skyrmions in 2D crystals

In the fast moving field of two dimensional materials, even a slight rotational shift between layers can dramatically change how a material behaves. Scientists previously discovered that when atom thin crystals are stacked with a small angular mismatch, their electronic properties can transform. This approach, known as moiré engineering, has…

Why tipping keeps rising and may not improve service

Why do people leave tips? According to new research, the answer comes down to two main motivations. Some customers tip to genuinely reward good service. Others tip because they feel pressure to follow social norms. The difference matters. Customers who truly value the service often leave more than the customary…

Scientists just turned light into a remote control for crystals

Scientists at NYU have developed a way to use light to guide how microscopic particles arrange themselves into crystals. The work, reported in the Cell Press journal Chem, describes a straightforward and reversible technique for building crystals that could support the creation of a new class of responsive, adaptable materials.…

Scientists discover the genetic switch that keeps your organs healthy

Scientists at the University of Liège have identified a crucial genetic regulator that allows macrophages to fully mature and help maintain organ health. This regulator, called MafB, acts as a “molecular switch” that turns specific genes on or off at precise moments and in specific cells. By controlling this genetic…

New crystal seeding method boosts perovskite solar cell efficiency to 23%

Conventional perovskite solar cells (PSCs) are structured with the electron transport layer underneath the perovskite light absorbing layer and the hole transport layer on top. Although this layout has delivered strong lab performance, it faces obstacles when scaled for large area manufacturing and long term stability. Inverted PSCs swap the…
