Atmospheric Particles Aren’t the Same Cloud Seeds They Once Were

Once there were twenty.

Aminoacyl-tRNA synthetases play a central role in protein synthesis by covalently linking the correct amino acid to the correct tRNA (1). Each aminoacyl-tRNA is then carried to the ribosome where it interacts with the cognate trinucleotide codon on the mRNA and transfers the amino acid onto a growing polypeptide chain. Work on tRNAs and aminoacyltRNA synthetases from bacteria, fungi, plants, an...

All adults once were children.

All adults once were children, and children exposed to unrelenting adversities or toxic stress are at risk for developing a multitude of health conditions that threaten their development and eventual adult health status. Pediatricians and their pediatric surgeon colleagues can help families and their children develop resiliency by properly addressing the needs of families and their children and...

How quickly do cloud droplets form on atmospheric particles?

The influence of aerosols on cloud properties is an important modulator of the climate system. Traditional Köhler theory predicts the equilibrium concentration of cloud condensation nuclei (CCN); however, it is not known to what extent particles exist in the atmosphere that may be prevented from acting as CCN by kinetic limitations. We measured the rate of cloud droplet formation on atmospheric...

Standardized patients versus simulated patients in medical education: are they the same or different

In order to equip medical students with all the necessary skills in dealing with patients to provide optimal treatment, the need for the use of real patients in educational settings has become prominent. But all the required skills cannot be practiced on real patients due to patients’ safety and well-being. Thus, the use of standardized patients (SPs) or simulated patients (SiPs) as a substitut...
