Tunisian snail remains provide insights on a possible 7700-year-old local food tradition
A new study by Dr. Ismail Saafi from the Aix-Marseille Université provides details on the discovery of cooked snail remains at Kef Ezzahi in northern Tunisia. The snail remains, dating back approximately 7710 years, are the only known cases of snail.....»»
AI and quantum mechanics team up to accelerate drug discovery
Drug discovery is much like working a jigsaw puzzle. The chemical compounds behind drug molecules must be shaped to fit with the proteins in our bodies to produce therapeutic effects. That requirement for a meticulous fit means the creation of new dr.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
