Early evidence of Near Eastern viniculture

Researchers discovered chemical evidence of grape wine in Georgia as early as 5400-5000 BC, and radiocarbon age determinations confirm Neolithic hunter-gatherers innovated viniculture around 5800-6000 BC. The study also found abundant grapes in the region during this period, highlighting deep historical roots of Georgian wine culture.

The hidden cost of crime: Tanzanians pay as much as 7 percent to protect money from theft

In Tanzania, consumers are willing to pay up to 7% for mobile money services that provide theft insurance against street robberies and home burglaries. The study found that people prefer to store cash in mobile wallets for short periods, with costs ranging from 1.52% per kilometer or 0.8% per day.

Urban trees are growing faster worldwide

A global study reveals that urban trees have been growing faster than rural trees since the 1960s, with an average growth rate of 20% across all climate zones. The heat island effect is believed to be the primary driver of this acceleration, leading to increased photosynthetic activity and prolonged vegetation periods.

Researchers put new spin on old technique to engineer better absorptive materials

A team of University of Illinois bioengineers has developed a new technique to characterize metal organic frameworks (MOFs) using infrared chemical imaging. This method allows for non-destructive analysis and provides detailed information on the structure and chemistry of MOFs, enabling better detection and utilization of these materials.

Parental Medicaid expansion translates into preventive care for their children

A recent analysis by the University of Pittsburgh Graduate School of Public Health found that when low-income parents enroll in Medicaid, their children have a significantly higher chance of receiving annual well child visits. These visits are crucial for growth and development, immunizations, and proper nutrition and child behaviors.

Record high CO2 emissions delay global peak

Global carbon emissions have surged in 2017 due to increased coal use in China and the US. The country's emissions are projected to grow by 3.5%, reversing two years of decline. This unexpected growth delays efforts to reach a global peak, with CO2 levels expected to rise to a record high.
