Air pollution may reduce health benefits of exercise

A new study found that long-term exposure to toxic air can weaken the health benefits of regular exercise. The study analyzed data from over 1.5 million adults and found that people living in high pollution areas had a reduced risk of dying, but not eliminated, despite exercising regularly. Clean air can still enhance health gains, wit...

Ancient DNA reveals a North African origin and late dispersal of domestic cats

A recent study by Marco de Martino and colleagues sheds new light on the domestication of cats, suggesting they originated from North African wildcats rather than the Levant. Genetic analysis reveals that true domestic cats only appeared in Europe and southwest Asia several thousand years after the Neolithic.

Metronome-trained monkeys can tap to the beat of human music

In a groundbreaking study, macaques were found to synchronize their taps with musical beats in real-time, even when presented with new songs. This ability to perceive and move to rhythm suggests that the roots of beat perception may be more widespread than previously thought.

Platform-independent experiment shows tweaking X’s feed can alter political attitudes

A new study using an AI-powered browser extension reveals that even small changes in exposure to hostile political content on X (formerly Twitter) can measurably influence feelings toward opposing political parties. The findings provide direct causal evidence of the impact of algorithmically controlled post ranking on a user's social m...

Study: New protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications

A new protocol for Treg expansion uses targeted immunotherapy to reduce transplant complications, boosting survival rates while preserving anti-cancer immunity. The protocol, led by Robert Levy, uses TL1A-Ig fusion protein and low-dose IL-2 to stimulate specific receptors on Tregs, promoting a safer environment for stem cell transplants.

Hematological and biochemical serum markers in breast cancer: Diagnostic, therapeutic, and prognostic significance

Serum markers such as NLR, PLR, ESR, LDH, ALP, creatine kinase-BB, SUA, CRP, and CA 15-3/27.29 have been linked to breast cancer diagnosis, prognosis, and therapeutic monitoring. These biomarkers offer affordable, non-invasive, and accessible diagnostic strategies for bridging the diagnostic gap in low-resource settings.

Non-invasive technology can shape the brain’s reward-seeking mechanisms

Researchers at the University of Plymouth have successfully used transcranial ultrasound stimulation (TUS) to change the function of a deep region of the human brain, specifically the nucleus accumbens. This tiny element is triggered by enjoyable experiences and helps us learn behaviours that lead to rewards.
