The Daily Dose: Ethics of informed consent and another urgent food warning

Ethics and informed consent: Human challenge studies in which scientists actively expose volunteers to a specific infectious disease in order to study it or to test the efficacy of potential new drugs can be ethically tricky. It gets even more tricky when the studies are conducted in poor countries where there is an inherent imbalance between the scientist and subject. Scientific American took a closer look at the practice.

Another urgent food warning: The CDC issued an urgent health warning “advising consumers, restaurants, and retailers not to eat, serve, or sell any romaine lettuce.” They believe an outbreak of E. coli O157:H7 infections are linked to romaine lettuce. 32 illnesses have been reported in 11 states. 13 people have been hospitalized, one with hemolytic uremic syndrome, a type of kidney failure.

Investing in antibiotic R&D: Roivant Sciences has made a $10 million investment into the development of new antibacterial drugs. The company made a payment to South Korean company, Intron Biotechnology, in order to license a mid stage drug that treats resistant bacaterial infections. The drug, SAL200 (Tonabacase) is a biological drug based on and enzyme derived from a bacteriophage.

Can you dig it?: Researchers working in China have struck paygold in the form of fossilized early marine animals called carapaces. The area where the dig is taking place provides a vivid window into the Cambrian age when modern animal groups made their first appearance in the fossil record.

Walking into history: Finally, last night in the NBA, the Charlotte Hornets’ Kemba Walker made history. He became one of only a handful or players to ever score 60+ points and 40+ points on back-to-back games.
