Sometimes nothing feels better on stiff, aching joints than a little heat. But many heating pads and wraps are rigid and provide uneven warmth, especially when the person is moving around. Researchers have now made a wearable heater by modifying woven Kevlar® fabric with nanowires that conduct and retain heat. They report their results in ACS' journal Nano Letters.
A laboratory experiment with 600 mock jurors has found the more severe an alleged crime, the higher a juror's confidence in guilt becomes, regardless of the evidence. 'If the crime is more serious or more heinous, [mock jurors] are more likely to be convinced by the same amount of evidence,' said lead study author John Pearson of Duke University.
Getting behind the wheel after cannabis use is on the rise in the US, and THC, not alcohol, is now the most commonly detected intoxicant in US drivers. Detecting levels of THC, however, is challenging and the methods used so far cannot accurately determine a person's level of impairment.
A new study looked at a nationally representative sample of Americans to identify factors related to individuals (e.g., political affiliation, gender) and states (e.g., voting patterns) that predict opposition to Black Lives Matter (BLM) movement.
A new study that estimated the effects of risk factors for black and white men and women found that black men were reincarcerated more often and more quickly than all others, despite having lower risk scores on nearly all of the variables on a standardized tool that assesses risk.
Questions about conscience protections for health care providers, how bioethics can shape artificial intelligence, a special report on citizenship and justice in aging societies, and more in the (September-October 2018 issue https://onlinelibrary.wiley.com/toc/1552146x/2018/48/5).
A major global report confirms gun-related homicides, suicides and accidents are falling in Australia after the introduction of anti-gun laws, and that the effect of such tough laws is similar elsewhere.
Developed countries imposing their own Security Sector Reform (SSR) processes onto nations recovering from war often rely on entrenched colonial attitudes with no guarantee of success. Research led by the University of Kent looked at the Democratic Republic Congo and Nepal contrasting their outcomes and examining the reasons for success or failure of SSR policies based on Europe. They question whether the systems work in their countries of origin where statistics show ongoing institutional racism.
Doping remains an ongoing problem in competitive sports, but researchers have never before asked athletes to rank the effectiveness of available anti-doping strategies. A new poll of a national pool of top German cyclists and field athletes finds that, according to the athletes, better diagnostics, increased bans and laws against doping are perceived as far more effective than increased fines or leniency programs.
