Researchers have discovered that the queen naked mole rat uses a distinctive chemical in her urine to suppress the reproductive systems of other females in the colony. This scent-based mechanism maintains the social hierarchy and prevents rivals from breeding. The finding sheds light on how social dominance is enforced in these highly structured animal societies.

The US government is implementing AI safety measures at both state and federal levels. These coordinated actions aim to reduce risks associated with artificial intelligence development. The efforts highlight growing official focus on preventing potential harm from AI systems.

Researchers have used hydrogen bonds to enhance the performance of blue LEDs made from perovskite materials. This approach improves the brightness and stability of the devices, overcoming a key challenge for next-generation display and lighting technologies. The findings represent a significant step toward commercializing perovskite LEDs.

An opinion piece in Nature argues that the world urgently needs a structured global conversation on inequality. It states that rising disparities threaten social stability and economic progress, and that international cooperation is required to address systemic imbalances. The article calls for scientists and policymakers to lead this debate with evidence-based approaches.

A new analysis highlights the strong correlation between improved educational opportunities and increased innovation. The research suggests that better access to education fuels innovation, which then creates new tools and methods to further enhance learning. This feedback loop is crucial for driving progress in society.

A study published in Nature found that a high-fat, low-carbohydrate diet can promote the growth of intestinal tumors. This challenges assumptions about the safety of such diets for cancer patients and highlights the need for tailored nutritional guidance.

Researchers have developed CAR T cells that target GPC3, a protein found in liver cancer cells, and are armored with a modified TGF-beta receptor to resist tumor suppression. This new approach aims to improve immunotherapy effectiveness against hepatocellular carcinoma, a common and deadly liver cancer. The advance could lead to more potent treatments for patients with limited options.

Researchers have developed an optical filter that can distinguish between different types of light based on their quantum statistics, effectively sorting bosons from fermions at the single-photon level. This breakthrough could enable new quantum technologies and deepen understanding of fundamental physics.

Researchers have found that nucleotides can function as molecular glue, binding proteins together, and also sense their own concentration in cells. This dual role suggests a new mechanism for cellular regulation, potentially impacting how DNA and RNA metabolism, signaling, and disease are understood.
