Crickets may feel pain, prompting welfare questions for billions farmed annually

A Royal Society B study tested 40 male and 40 female house crickets (Acheta domesticus) by applying a heat stimulus to an antenna and found they groomed the heated area significantly longer than controls, indicating pain-like responses beyond a reflex. With crickets being the world’s most farmed insect (about 370 billion annually), this suggests insects may have subjective experiences and underscores the need for welfare protections as giant-scale farming continues and concerns about animal suffering grow.

Seniors Seek 'Goldilocks' Cannabis for Pain, Sleep, and Mood

A Colorado study of 169 adults aged 60+ found that older first-time cannabis users mainly seek relief from pain, sleep problems, and mental health concerns to improve quality of life, not to get high. They often rely on word-of-mouth rather than healthcare providers, and many favor CBD–THC combination edibles—the so-called 'Goldilocks option'—as a balanced approach. The findings point to a need for better patient–provider information and clinical tools to guide safe, effective use, especially as legal and regulatory contexts vary by state.

Lab-Grown Brain Organoids Spark Pain Question and Ethics Debate

Researchers are growing brain organoids and assembloids to study brain diseases and even model pain pathways, but the organoids are not conscious and remain developmentally immature; the debate now centers on ethics and governance, especially around transplanting human organoids into animals and balancing potential therapies with welfare concerns.

Immune signals and hormones may explain why women's pain lingers longer

New research combining mouse experiments with human vehicle‑crash data suggests that pain after injury lasts longer in women because monocytes produce less IL-10, a molecule that both reduces inflammation and directly dampens pain signals; testosterone boosts IL-10 production in male monocytes, helping men recover faster. This shifts the view of the immune system from solely driving pain to also helping resolve it, pointing to therapies that enhance the body's natural pain‑resolution pathways to prevent chronic pain.

Immune ‘Off-Switch’ for Pain Found to Differ by Sex, Study Shows

A new Science Immunology study links IL-10–producing monocytes to an immune brake that dampens pain after injury. In mice, males had more IL-10–producing cells and recovered faster, with pain lasting longer when IL-10 or its receptor was blocked. Human data from the AURORA trauma study showed higher IL-10 levels at injury in men and lower subsequent pain, suggesting a biological basis for women’s longer-lasting pain. While not the sole pathway for all chronic pain, the findings point to immune signaling as a potential target, with ideas like skin-applied testosterone to modulate IL-10–positive monocytes under exploration (noting more research is needed).

Immune cells and hormones may explain why women's pain lasts longer

New research in mice and humans suggests that immune cells produce IL-10 to help resolve pain, and sex differences in this response—shaped by testosterone—may explain why women often recover more slowly from injury and have a higher risk of chronic pain. These findings point to therapies that boost the body's natural pain-resolution system rather than only blocking pain signals.

Stem-cell derived 'pain sponge' targets pain at the source in arthritis

Researchers engineered human pluripotent stem cell–derived sensory neurons that act as a biological "pain sponge," soaking up inflammatory pain signals at the site of inflammation in mice with osteoarthritis and also promoting bone and cartilage repair. The SN101 approach is in preclinical stages, with safety, immune response and translation to humans unresolved and no peer‑reviewed human data yet.

Gene Therapy Targets Pain Circuits to Relieve Chronic Pain Without Addiction

A preclinical CNS-targeted gene therapy dampens pain signals in specific brain circuits to relieve chronic pain while avoiding the brain reward pathways tied to addiction, using AI-guided imaging and animal models, with an off switch for long-lasting relief and moving toward clinical trials to help the roughly 50 million Americans affected by chronic pain.

Scientists May Have Unraveled the Mystery of Fibromyalgia Pain

A large genetic study has identified 26 genetic regions linked to fibromyalgia, revealing that the condition primarily originates in the brain's neural circuits that control pain sensitivity, rather than in muscles or joints. The findings suggest fibromyalgia is related to nervous system hypersensitivity and shares genetic links with other disorders like chronic fatigue and PTSD, offering new avenues for early detection and targeted treatments.

Brainstem Circuits as Key Regulators of Chronic Pain and Need-State Control

The study identifies Y1 receptor-expressing neurons in the lateral parabrachial nucleus as key modulators of long-term pain, showing that their activity correlates with persistent pain states and can be suppressed by need states like hunger and thirst through NPY signaling, which gates nociceptive input to promote survival.

Reddit Insights: Men’s Experiences with Vasectomy Pain and Regret

A study analyzing Reddit posts reveals that many men experience fear, regret, and persistent pain after vasectomy, challenging the perception of it being a largely risk-free procedure. The findings highlight the importance of transparent, nuanced communication about potential long-term outcomes to ensure truly informed consent, especially as online discussions increasingly influence health decisions.

Old Injuries Cause Lasting Changes in Brain's Fear and Pain Response

A study shows that past injuries can cause long-term hypersensitivity to fear and pain by involving stress hormones and the TRPA1 receptor, which may explain chronic pain and trauma-related disorders. The research highlights that fear and pain, while related, are driven by different biological pathways, offering potential targets for treatment.
