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.

I can see my house lights!  Click here to check out global composite night time images of Earth in stunning clarity.

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!

While You Were at the Bench: Week 44

The hole in the ozone layer over Antartica reached its smallest maximal size in the last two decades.  NASA and NOA scientists believe the warmer temperatures in the Antartic this year helped reduce the damage to the ozone layer caused by chlorofluorocarbons.

Researchers have engineered a macromolecule that not only inhibits the IgE-Fc Receptor but also dissociates preformed ligand-receptor complexes. This could lead to a new class of fast-acting medication for acute allergic reactions.

Researchers at Stanford University have created the first all carbon solar cell.  While they acknowledge the efficiency (< 1%) is considerably lower than commercially available photovoltaic solar cells, the carbon-based thin film technique can dramatically reduce the cost associated with solar cells.

We already know that redhead, fair skinned individuals are more susceptible to melanoma caused by ultraviolet radiation.  However, new research in ginger mice suggests redheads might develop melanoma through a mechanism of oxidative damage without exposure to the sun.

Researchers at UC Santa Barbara have discovered that Notch signaling is essential for determining cell fate during embryogenesis in C. elegans.  Blocking this signal could lead to new ways of “growing” replacement organs for humans.

And in an update to a former post, the International Thermonuclear Experimental Reactor (ITER) is being delayeddue to a complicated contract process.  The first scheduled energy producing experiments aren’t scheduled until 2027 or 2028.

A great place to go for a run.

Researchers in Montreal have shown that middle-aged, overweight individuals who exercised four days a week for four months not only lost weight, but also improved their cognitive function.  Now, put down that plate of poutine, visit RateMyPI.com, and hit the gym.

Have a great weekend!
