The Rialto experiment showed that evidence capture is just one output of body-worn video, and the technology is most effective at preventing escalation during police-public interactions. The 'preventative treatment' of body-worn-video relies on the combination of the camera plus cognition of surveillance, causing individuals to modify ...
Researchers found that hunter-gatherers had stronger bones compared to farmers from the same region, with a 20% difference in bone mass. The study suggests that physical activity is key to preventing bone weakening and conditions like osteoporosis.
The IMF's economic policies have been shown to reduce government spending on healthcare, leading to underfunded and understaffed health systems. The researchers argue that the IMF's campaigns for decentralised healthcare systems also hinder coordinated responses to outbreaks, such as Ebola.
Researchers found that OCD patients were less capable of stopping pedal-pressing habits due to excessive caudate nucleus activity, linking compulsions to the brain's habit system. The study suggests that habits may be behind various psychiatric behaviors, including drug abuse and binge-eating.
Research from the University of Cambridge suggests that a simple supplement could reduce heart disease risk in individuals born with low birth weight. The study found that a molecule called CoQ prevented cells in the aorta from ageing prematurely, which can lead to heart disease.

Researchers discovered sustained human habitation and farming between 2,500-3,400 meters above sea level 3,600 years ago on the Tibetan Plateau. This finding challenges previous understanding of human adaptation to high altitudes.
A new study reveals that females have evolved a highly-effective counter-strategy to stop males from killing their offspring: by having multiple mates in a short time, causing paternity dilution and reducing infanticide risk. This leads to increased testis size in male mouse lemurs as they produce more sperm to outcompete others.
Research on tool use by primates suggests that ecological opportunity, rather than necessity, is the main driver behind their use of tools. The study found that tool use was not influenced by food scarcity, but rather by calorie-rich and hard-to-reach resources.
The HIP HOP PSYCH initiative aims to use hip-hop lyrics and music to improve people's mental health, address stigma towards mental illness, and increase diversity within the psychiatric profession. By integrating hip-hop into psychotherapies, psychologists can refine their tools to make therapies more relevant to specific populations.
A new study on ancient DNA from a 36,000-year-old fossil in western Russia found that the earliest European humans' genetic ancestry survived the Last Glacial Maximum.

Scientists call for better integration of experimental data, computational methods, and mathematical models to predict pandemic risk. They stress the importance of remaining vigilant against unknown high-risk viruses.
A new study reveals five high-risk Ponto-Caspian species, including the quagga mussel and killer shrimp, have established themselves in Britain. The invasion is expected to lead to devastating consequences for native species, with up to twenty additional species projected to arrive in the near future.
A survey of 577 people in southern Ghana reveals that hunters and consumers perceive the risk of infection from eating bat meat as low, despite handling live bats and coming into contact with bat blood. The study finds that regulations alone are not effective solutions to reduce the practice.
A new study finds that more healthy foods have risen significantly in price over time, with a total average increase of £1.84 per 1000kcal for more healthy food across the decade, compared to £0.73 for less healthy food. This trend could contribute to growing food insecurity and health inequalities.
The Greenland Ice Sheet is more sensitive to climate change due to the role of soft ground beneath it, which affects its dynamics and leads to increased ice loss. This study reveals that the ice sheet is vulnerable not only to warming temperatures but also to extreme meteorological events like heavy rainfall and heat waves.
Researchers discovered that autism with early language delay is associated with smaller brain volume in key regions and larger brainstem structures. Current language function also impacts grey and white matter volume changes in specific brain areas.

Researchers at the University of Cambridge discovered that stem cells 'communicate' with damaged cells by transferring molecules via fluid-filled bags called vesicles, helping other cells modify the damaging immune response. This novel mechanism enables stem-cell-based therapies to work more efficiently.
Global homicide rates have been declining since the mid-1990s, with an average drop of 40% in 15 years.

This discovery raises questions about exoplanet formation and highlights challenges in searching for water on Earth-like planets.
A new study found that genetic variations, particularly imprinted genes, play a significant role in determining the age of puberty in girls. The research analyzed DNA data from over 180,000 women and identified six imprinted gene variants associated with earlier or later menstrual cycles.
Researchers found a link between antipsychotic medication and reduced brain volume in schizophrenia patients, but no impact on cognitive function or symptoms over a nine-year follow-up. The study suggests that both older and newer antipsychotics may be associated with similar declines in brain volume.
