Worm Defies Tradition, Stores Gut Bacteria in Gills Instead

by Elizabeth Preston in Inkfish

What—just because they’re called gut microbes, you’ve been keeping them in your colon? How unoriginal. This is Bankia setacea, also called the Northwest or feathery shipworm. Humans usually pay attention to shipworms only when they perform their namesake activity: burrowing face-first into our boats or docks and eating their way through. Shipworms are bivalves, like clams […]The post Worm Defies Tradition, Stores Gut Bacteria in Gills Instead appeared first on Inkfish.... Read more »

A Big Break for Bio-Gasoline

by Gabriel in Lunatic Laboratories

While the world waits for a better battery (and a energy grid system that doesn't require constant power making), scientists are hard at work trying to teach old fuels a new trick. Thankfully an international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, if it is not obvious, is a significant step toward developing a bacterial strain that can yield industrial quantities of renewable bio-gasoline.... Read more »

Steak is bad for the Heart and now We Know why

by Gabriel in Lunatic Laboratories

“Red meat is bad for your heart”, that is typically the story we hear from people. While some might take this as meat is bad for us, or that it is wrong to eat red meat, science has been trying to find a better answer to that question. After all it wouldn’t do for science to say, it just does. Well as luck may have it, new research provides details on how gut bacteria turn a nutrient found in red meat into metabolites that increase the risk of developing heart disease. The findings may lea........ Read more »

Understanding the past to know more about our future: study finds spikes in carbon dioxide levels correlated with end of last glacial cycle

by Jonathan Trinastic in Goodnight Earth

We've always thought that the last glacial cycle correlated with a slow rise in CO2, however new data from Antarctica shows quick spikes in CO2 and methane lasting under 100 years. This data could provide new insights into the carbon cycles useful for understanding today's CO2 increases.... Read more »

NS1: It’s all about location, location, location

by Clay Clark in Biochem Blogs

  Viruses are minimalists when it comes to genomic data. This light packing of genetic information requires that every protein the virus codes for needs to be as versatile as possible. The flavivirus genus is no exception to this; its genome encodes for three structural proteins (capsid, membrane, and envelope) and seven nonstructural proteins (NS1, […]... Read more »

DNA Nanotech: The First Large DNA Crystals

by Gabriel in Lunatic Laboratories

DNA is the stuff of life as we know it, but it is the potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology, and more. Researchers have been working to master the ability to coax DNA molecules to self assemble into the precise shapes and sizes needed in order to fully realize these nanotechnology dreams. A dream that been going on for 20 years now and was just realized.... Read more »

A look at Air Pollution and Your Body

by Gabriel in Lunatic Laboratories

We have all probably seen stories from China on the horrid air pollution there. Accompanying those reports of course are the statistics for air pollution that deaths have caused. For the record, the World Health Organization estimated that ambient air pollution caused 3.7 million premature deaths (worldwide) in 2012 alone – yet what exactly happens to your body when it encounters pollutants?...

Ebola Virus VP40 -A protein straight out of “transformers”

by Clay Clark in Biochem Blogs

  Ebola. Just the word is enough to make people panic. Well “Ebola” is actually just a river in the Democratic Republic of the Congo. Of course when they hear the word, most people think about the deadly virus discovered near this river in 1976. To clarify the terminology, “Ebola” is the river; “Ebolavirus” is […]... Read more »

Solar Panel Hybrid is Cheap and Super Efficient

by Gabriel in Lunatic Laboratories

Solar cells are inefficient, it’s a sad fact. With todays technology they boast about a 10-15% efficiency, compare that to todays gas engine at roughly 20-25% and you can see it’s not quite up to par. Well that could all change very soon thanks to a new method for transferring energy from organic to inorganic semiconductors. This could boost the efficiency of widely used inorganic solar cells to as close as 100% efficiency as they can get.... Read more »

Using “Programmable” Antibiotics to Attack Drug-Resistant Microbes

by Gabriel in Lunatic Laboratories

The body is pretty great at self regulation, that is up until it isn't. The antibiotic era was one that improved human health hundreds of times over. Unfortunately health is a joint effort, a multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once like a wild fire, reg........ Read more »

Survivin: You wouldn’t be alive without it

by Clay Clark in Biochem Blogs

  Enzymes perform numerous tasks in order to contribute to the global goal of organism survival. One such enzyme is Survivin. Survivin wears many “hats” within the cell and is a vital part of cellular homeostasis. Here I will introduce you to two of the main processes Survivin regulates. Survivin is a multifunctional protein involved […]... Read more »
