Molecule-level ‘CT scans’ could lead to faster drug discovery

Scientists like to use x-rays when determining chemical structures to develop drugs, but it’s an agonizingly slow process. As they need large, pure crystals, it can take weeks or even years to produce something big enough for studying. However, that time might be cut down to a matter of minutes. Researchers have developed a CT […]

Ancient city’s LiDAR scans reveal as many buildings as Manhattan

When researchers surveyed the ruins of a Purépecha Empire city in Mexico the old-fashioned way a decade ago, it took them two seasons to explore two square kilometres. Good thing they decided to use LiDAR, because the city called Angamuco turned out bigger than they previously thought. LiDAR gave the researchers the power to see […]

Artificial intelligence has learned to spot suicidal tendencies from brain scans

Arnd Wiegmann/Reuters Clinicians normally have few tools to identify suicidal people at risk. A new machine-learning technique using words could help identify those suffering from suicidal thoughts. Suicide is the second-leading cause of death among young people between the ages of 15 and 34 in the United States, and clinicians have limited tools to identify those […]
