Mining the microbiome: Uncovering new antibiotics inside the human gut      (via sciencedaily.com)     Original source 

Researchers surveyed the gut microbiomes of nearly 2,000 people, discovering dozens of potential new antibiotics. The lead candidate, prevotellin-2, demonstrated anti-infective capabilities on par with polymyxin B, an FDA-approved antibiotic used today to treat multidrug-resistant infections, suggesting that the human gut microbiome may contain antibiotics that will someday find clinical application.

Versatile fluidic platform for programmable liquid processing      (via sciencedaily.com)     Original source 

Society relies heavily on diverse fluidic technologies. The ability to precisely capture and release various chemical and biological fluids plays a fundamental role in many fields. A long-standing challenge is to design a platform that enables the switchable capture and release of liquids with precise spatial and temporal control and accurate volumes of the fluid. Recently, researchers have invented a new method to effectively overcome this challenge.

The banana apocalypse is near, but biologists might have found a key to their survival      (via sciencedaily.com)     Original source 

The bananas in your supermarket and that you eat for breakfast are facing functional extinction due to the disease Fusarium wilt of banana (FWB) caused by a fungal pathogen called Fusarium oxysporum f.sp. cubense (Foc) tropical race 4 (TR4). However, thanks to recent research from an international team of scientists we now know that Foc TR4 did not evolve from the strain that wiped out commercial banana crops in the 1950s and that the virulence of this new strain seems to be caused by some accessory genes that are associated the production of nitric oxide. The research opens the door to treatments and strategies that can slow, if not control, the as-of-yet unchecked spread of Foc TR4.

Enhancing electron transfer for highly efficient upconversion OLEDs      (via sciencedaily.com)     Original source 

Electron transfer is enhanced by minimal energetic driving force at the organic-semiconductor interface in upconversion (UC) organic light emitting diodes (OLEDs), resulting in efficient blue UC-OLEDs with low extremely turn-on voltage, scientists show. Their findings deepen the understanding of electron transfer mechanisms in organic optoelectronic devices and can lead to the development of efficient new optoelectronics without energy loss.

Recent trials of an experimental malaria vaccine in healthy Malian adults found that all three tested regimens were safe. One of the trials enrolled 300 healthy women ages 18 to 38 years who anticipated becoming pregnant soon after immunization. That trial began with drug treatment to remove malaria parasites, followed by three injections spaced over a month of either saline placebo or the investigational vaccine at one of two dosages.
