Researchers discover the key to staying dry underwater

Oftentimes, the state of being “underwater” and being “wet” are used synonymously, but one can be wet without being underwater; and according to researchers at Northwestern University, one can be underwater without being wet (1). Through a combination of analysis of “air-retaining insect surfaces” used by aquatic insects, aging and...

 
 

High levels of CO2 threaten oceans

The oceans, Earth’s great bodies of water, help keep the climate stable by stopping dramatic temperature changes with their ability to slowly absorb and release heat. They also provide a home to millions of marine ecosystems. However, lately, this great safe-haven is being threatened by an increase in greenhouse gas emissions. (1) In...

 
 

Promising breakthrough in Cystic Fibrosis research: Nebulization of CFTR gene therapy

For the first time, a non-viral gene therapy in a phase 2 trial has been demonstrated to be advantageous to lung function in people afflicted with cystic fibrosis (1). Normally, people with cystic fibrosis have one or more mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. These mutations...

 
 

High testosterone levels in female athletes: Weighing in on the debate

In a recent case at the “Supreme Court of Sport” in Switzerland, female Indian sprinter Dutee Chand challenged a policy that prevents women with naturally high testosterone levels from competing against other female athletes. The policy, enacted by the International Association of Athletics Federations (IAAF), prohibits women whose testosterone levels...

 
 

Mobile Phone-Based Nanomedicine

The mobile phone-based microscope that Wei and colleagues in the Ozcan Lab at UCLA developed in 2010 was portable, cost-effective, easy to use, had high sample throughput, and could be mass-produced.

On March 5, Qingshan Wei, Postdoctoral Scholar in Electrical and Bio-engineering at UCLA, gave a seminar on his research into developing mobile phone-based systems for imaging, sensing, and diagnostics. Although the first compound microscope was invented in 1595, the past three decades have seen rapid advances in imaging technology. However,...
