Looking Past Peer Influence: Genetic Contributions to Increases in Teen Substance Use?

Parents and adults spend a lot of time worrying about the influence of peers when it comes to teen substance use. Using a unique sample of 476 twin pairs who have been followed since birth, a new study examines if there is a genetic component that drives teens’ desire for risk taking and novelty.

Anesthesia Drug Shortages Negatively Affecting Patient Care, American Society of Anesthesiologists (ASA) Survey Finds

A national drug shortage crisis is potentially affecting the care received every day for thousands of patients undergoing anesthesia. In an informal ASA member survey, more than 98 percent of respondents noted that they now regularly experience drug shortages at their institutions and more than 95 percent of respondents said the shortages impact the way they treat their patients.

Molecular Evolution: How the Building Blocks of Life May Form In Space

JCP010815_GlycineFormation_Huels_AJ_IMAGE.jpg

In an experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia and carbon dioxide, the building blocks of life. The experiment tested how the combination of electrons and basic matter leads to more complex biomolecule forms -- and perhaps eventually to life forms. The researchers discuss their work in The Journal of Chemical Physics.

Scientists identified light-induced electrical activity as the brain mechanism controlling chemical code switching related to stress. While studying neurotransmitter switching in rats, they found that specific neurons were responsible, with implications for imbalances underlying mental illness.

EPA’s New Requirement for Scientific Studies is An Attack on Science, Says ATS

In a huge blow to public health, EPA administrator Scott Pruitt announced a new rule that would only allow EPA to consider research studies for which the underlying data are available to the public, thus severely limiting the number of scientific studies that the EPA can use in setting health standards. The new requirements blocking the use of most scientific studies will help big polluters avoid regulations that protect human health.
