Study: Too Many Kids With ADHD Given Antipsychotic Drugs
  • Study shows that 2.6% of youths diagnosed with ADHD were prescribed antipsychotic drugs within a year of diagnosis.
  • This is four times more than among young people in general, and it was even higher (4.3%) in children aged 3-5 diagnosed with ADHD.
  • Children using antipsychotic drugs are at bigger risk for weight gain, hyperlipidemia, diabetes, and even unexpected death.
  • Many physicians prescribe antipsychotics without first trying less dangerous stimulants like Ritalin and Adderall, which are recommended for treating ADHD.

Particulate matter air pollution and national and county life expectancy loss in the USA: A spatiotemporal analysis
  • Exposure to fine particulate matter pollution (PM2.5) continues to harm the health of Americans.
  • Study based on population-wide US data from 1999 to 2015 linked PM2.5 pollution to an estimated 15,612 deaths in females and 14,757 in males.
  • The study is observational and cannot prove causality, but it still shows that lowering PM2.5 pollution could benefit the health of the entire US population.

Bacteria-killing gel heals itself while healing you
  • New antibacterial gel uses bacteria’s natural enemy - phages (about 300 trillion in 1 millilitre) - and could have numerous medicinal and environmental applications.
  • The creators grew, extracted, and mixed enough phages that they became liquid crystals, and formed into a gelatin-like substance that heals itself when cut.
  • Phages are the most numerous organisms on Earth, they’re everywhere.
  • The key aspect of creating the gel was concentrating enough phages to create a solid material.
  • Phages are a promising alternative to current methods of killing bacteria, especially since they can kill antibiotic-resistant bacteria.

Exposure to common chemicals in plastics linked to childhood obesity
  • Based on data from US health surveys, researchers found that replacements for harmful industrial chemical bisphenol A are harmful, too.
  • Bisphenol S (BPS) and F (BPF) are used in different plastics, and exposure to these chemicals is very common in the US.
  • Although diet and exercise are still the main drivers of obesity, these chemicals could contribute to the problem in children.
  • Children with greater levels of BPS of BPF in their organisms were more likely to have obesity compared to children with lower levels.

Artificial throat could someday help mute people ‘speak’
  • New device, created by laser-scribing graphene on a thin sheet of polyvinyl alcohol film, could be used to help mute people communicate.
  • Existing detectors for measuring human skin movements can’t convert these motions into sounds.
  • This device is capable of it, but it’s far from being the end-product, and another version is already in development.
  • It would be thinner, skin-like, and would stick to the neck like a temporary tattoo.
  • This would enable mute people to use their throats to control a speaking device.
