Functionalizing an AFM tip with a single hydrogen atom

Researchers demonstrated the controlled vertical manipulation of a single hydrogen (H) atom using the tip of an atomic force microscope sensor and its application in characterizing and engineering silicon dangling bond-based structures of relevance to nanoelectronic devices.

Optimization for self-production may explain mysterious features of the ribosome

A new study explains the previously mysterious characteristics of ribosomes, the protein production factories of the cell. Researchers mathematically demonstrated that ribosomes are precisely structured to build themselves as quickly as possible to support efficient cell growth.

Patients taking opioids prior to ACL surgery more likely to be on pain medications longer

More than 130,000 Anterior Cruciate Ligament (ACL) surgeries take place each year with the majority of patients not requiring pain medication after three months post-operatively. However, researchers have found that those patients who were filling opioid prescriptions prior to surgery were 10 times more likely to be filling prescriptions five months after surgery.

New insight into genetic basis of neuropsychiatric disorders

New insight into the genetic basis of neuropsychiatric disorders has been provided through new study. In this research, the first mouse model of a mutation in the ARID1B gene was created and then used to show that growth hormone treatments reverse some manifestations of the mutation.

Name that scotch: Colorimetric recognition of aldehydes and ketones

Vodka tastes different from brandy, and connoisseurs can distinguish among different brands of whiskeys. The flavors of spirits result from a complex bouquet of volatile compounds. New colorimetric sensor arrays on disposable test-strips read by hand-held devices allow for their rapid, inexpensive, and sensitive identification by their chemical ‘fingerprints’. They are based on novel sensor arrays that detect and differentiate among a diverse range of aldehydes and ketones.
