Week 6 Schedule: Section B
How are chemical reactions and energy related? What does it mean to transfer energy? How can we get usable energy out of chemical reactions? How can we measure these properties?
This week we will be answering these questions and more while we study Thermochemistry!

Week 4: CH141 B Schedule
Which chemical reactions happen in our water sources like the the Belgrade Lakes? How does the fluoridation of drinking water protect tooth enamel? How do plants react when eaten by a caterpillar? To answer these questions (and many more!) we first need to explore how chemistry happens in the aqueous phase!
This week we will learn about different types of reactions that can happen when molecules are dissolved in water.
Reminder: Our first exam will happen on Monday, Oct. 1st from 5pm -7pm. More information can be found here. There will be an optional review session on Sunday, September 30 starting at 7:00 pm in Keyes 105.

Can mRNA disrupt the drug industry?
Used by all living things to make proteins, messenger RNA is one of the least explored frontiers of drug discovery. Moderna Therapeutics, and an increasing number of similarly well-funded biotech firms, is built on the promise that mRNA can be turned into a powerful treatment for genetic diseases, cancer, infectious diseases, and more. But turning mRNA into a drug is far from trivial, and companies have kept their technology largely under wraps. Now, Moderna is offering a glimpse of its massive research engine. Read on to learn how researchers are trying to move mRNA out of the lab and into the clinic. – Read more.
