A recent study found that two-thirds of studies on 'psychosocial' treatments list co-authors who financially benefit from the treatments, yet few declare a conflict of interest. This lack of transparency may lead to biased research and influenced policy decisions.
A study published in Nature Communication found that a protein called sLR11 acts to inhibit thermogenesis, or heat production, in fat cells, making it harder for the body to burn excess fat. This protein is produced by fat cells and increases with total fat mass, suggesting its role in storing energy over long periods.
Researchers at the University of Cambridge found that people with compulsive sexual behavior seek out new sexual images more frequently than others. They are also more susceptible to environmental cues linked to sexual images, which can trigger their addiction.

Researchers discovered plague has been endemic in human populations for over 3,000 years, with evidence of infection dating back to the Bronze Age. The bubonic form of plague spread through flea carriers after genetic mutations allowed Yersinia pestis bacteria to survive in human guts.
A new study has found that changes in the polar regions can significantly affect the ocean and climate on the opposite side of the world, far quicker than previously thought. The research linked ocean currents to climate conditions during the last ice age, revealing a tight connection between the two.
Experts' advice is often compromised by subjective influences and biases, warn researchers. They suggest integrating expert judgements with evidence-based approaches to improve accuracy and reliability.

Researchers found that individuals with early signs of psychosis relied more heavily on prior knowledge to interpret ambiguous images, leading to improved task performance. This suggests an altered balance in normal brain functions contributing to the emergence of mental illness symptoms.
The sequenced ancient human genome from Africa reveals a significant wave of migration back into the continent around 3,000 years ago, affecting all populations across the African continent. This migration predates the 'Eurasian backflow' event and shares genetic similarities with Early Neolithic farmers who brought agriculture to Europe.
Insects like stick insects can walk up vertical surfaces using adhesive pads on their feet, but scientists long believed that wet and dry feet required different mechanisms to adhere. New research reveals that the fluid on their feet plays a crucial role in controlling adhesion, with potential applications in modern devices.
Research found that young male chimpanzees spend more time manipulating objects in play, but it does not prepare them for adult tool use. In contrast, immature females show a greater diversity of manipulation types and learn to use tools earlier.
Researchers estimated that cyanobacteria in the oceans produce between 300-800 million tonnes of hydrocarbons per year. This production dwarfs crude oil releases by natural seepage or accidental spills.
