Development of novel fluorogenic probes provide valuable insights regarding the polarity of cancer cell membranes.
Boosting student confidence with micropipette color wheels
Many students learn about how to use the persnickety micropipette while performing other,critical reactions. However instructors at Montmouth College designed a unique teaching exercise to instill confident micropipette usage using color wheels.
Ozone Is The Key To Effective Lipid Detection And Isomer Resolution
Lipids are an important class of biological molecules where the physical and chemical structure will impact its function in our body. Effective lipid detection and analysis are key to understanding specific lipid interactions and overall biological impact. This paper discusses development of new analytical detection technique for mass spectrometry which provides greater insight into lipid biological chemistry.
The Montreal Protocol – a policy saving lives by closing the Antarctic ozone hole
Since it’s ratification in 1987, the Montreal Protocol has saved millions of people from skin cancer and cataracts. This success is due to global collaboration and an effective use of science in policy.

Monitoring plant maturation with a Wack reaction
When the authors’ blurb about their own work is “Okay, bloomer,” you know you have to read it.
The Smell of Success
Although skunks are nocturnal animals that prefer their own company, they won’t hesitate to spray potential predators, people or pets with fluid from their anal glands. For many years, these anal secretions have fascinated natural products chemists but repelled most of the rest of us. Learn about a new way to “de-skunk” from researchers at the University of Oklahoma.
