Detection of Bath Salts in Biological Samples is Difficult

Synthetic cathinones are derived from cathinone which is present in the khat plant. These recreational drugs produce effects similar to amphetamines and have been associated with numerous fatalities.

Although the Drug Enforcement Administration (DEA) banned some synthetic cathinones in 2011, new designer drugs continue to appear, presenting a real challenge for forensic laboratories. The report was published in the Journal of Analytical Toxicology.

An Adult Brain Can Produce New Neurons

Scientists have established that the new neurons produced in adults react preferentially to reward-related sensory stimuli and help speed up the association between sensory information and reward. Adult-born neurons therefore play an important role in both the identification of a sensory stimulus and the positive value associated with that sensory experience. This stuyd has published in  Proceedings of the National Academy of Sciences (PNAS).

To Create Nanoscale Materials By Using DNA Material

A team of researchers has produced 3-D images from 129 individual molecules of flexible DNA origami particles. Their work provides the first experimental verification of the theoretical model of DNA origami. Over the past decade, researchers have been working to create nanoscale materials and devices using DNA as construction materials through a process called "DNA origami." The study has published in Nature Communications.
