While You Were at the Bench: Week 49

A small clinical trial has demonstrated that colorectal cancer can be detected in patients by analyzing the volatile organic compounds in their exhaled breath with up to 75% accuracy.  While further studies are required to improve the accuracy, this noninvasive screening method could be applied to detecting other types of cancers.

Voyager 1, launched in 1977, has reached the boundary of our solar system and could be the first craft to pass beyond our solar system in months to years.  Despite being 11 billion miles from Earth, Voyager 1 is still able to transmit scientific data albeit 17 minutes delayed.

Researchers in The Netherlands have discovered that maggot secretions degrade complement proteins thus preventing inflammatory responses thereby helping open sores and wounds to heal faster.  Unfortunately, a topical cream is several years away.

Using tunable plasmonic nanobubbles, researchers at Rice University were able to kill cancer cells while simultaneously performing gene transfer in healthy cells of the same sample.  This rapid procedure can help improve the safety and efficacy of cell and gene therapy or bone marrow transplantation.

First soil samples analyzed by Curiosity indicate water, sulfur, chlorine and carbon on the Red Planet’s surface.  While it is too early to claim organic compounds, the recent success has led NASA to announce another rover sent to Mars by 2020.  No word on sending a rover to Titan. Might it be because the ice is thicker than originally thought?

High levels of dichlorophenols typically found in herbacides and pesticides have been linked to food and other environmental allergens in 64.5% of the study participants.  By the way, did I mention that dichlorophenols are also used in water chlorination.

Extroversion may increase lifespan….at least in gorillas.  An 18 year longitudinal study of 283 captive gorillas has shown that those with high social, play, and curiosity behaviours were linked with increased survival.

Now go get out of the lab and Have a Great Weekend!
