Bacteria get new badge as planet's detoxifier

A study published this week in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual.

Engineered bacteria produce biofuel alternative for high-energy rocket fuel

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications.

"Social" bacteria that work together to hunt for food and survive under harsh conditions

When considering the behavior of bacteria, the word "social" doesn't often come to mind. Yet some bacteria are quite social, chief among them Myxococcus xanthus, a soil-dwelling bacterium that organizes itself into multi-cellular, three-dimensional structures made up of thousands of cells that work together to hunt for food and survive under harsh conditions.

How bacteria respond so quickly to external changes

Understanding how bacteria adapt so quickly to changes in their external environment with continued high growth rates is one of the major research challenges in molecular microbiology. This is important not least for our understanding of resistance to antibiotics. A research study from Uppsala University is now presenting a model of how bacteria can rapidly adapt to environmental changes through smart regulation of their gene expression.

High-octane bacteria could help at the pump

New lines of engineered bacteria can tailor-make key precursors of high-octane biofuels that could one day replace gasoline.

Bacteria exploits hydrogen, carbon dioxide to produce electricity

Researchers have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.

Bacteria to power your gadgets

A technique that tethers bacteria to electrodes means your future gadget could be powered by microbes in the future.

Algae steals genes to survive toxic environment

A species of algae that can cope with 'battery acid' conditions managed it by copying genes from bacteria.

Bacteria found thriving in troposphere

Large numbers of microorganisms, mostly bacteria, have been discovered five miles up in the sky.

Clues for bacteria on Mars could be found in Río Tinto

Researchers at the Centre of Astrobiology have positively identified microorganisms living inside salt deposits in the acidic and ferrous environment of the Tinto River in Huelva, Spain.

Genetically engineered bacteria grow fuel from sunlight

Scientists have engineered bacteria to make the precursor chemicals for fossil fuels and plastics, a breakthrough for the chemical industry.

Ancient microbes tough it out in Antarctic lake

Scientists have discovered a group of microorganisms capable surviving one of the toughest environments on our planet: ancient bacteria living under 65 feet of ice at the bottom of a brine-filled lake in Antarctica. 

'Living electrical cable' discovered on sea bed

Researchers have discovered an extraordinary type of bacteria that creates electrical currents on the ocean floor.

Ocean bacteria colonized land billions of years ago

Researchers at the University of Washington have determined that "some" microbial life migrated from the Earth's oceans to land some 2.75 billion years ago.

Bacteria turn CO2 into soil improver

Tiny microbes and a tropical tree can be used to lock up carbon dioxide - and turn it into an agricultural soil improver.

Thousands of bacterial species live on every person

You're carrying around over 10,000 different species of bacteria in and on your body right now, in such numbers that they weigh several pounds.

Bacteria discovered after 86 million years

Living bacteria have been discovered deep beneath the ocean where they've had no new food or oxygen since dinosaurs roamed the earth.

Hard drives could be built using magnetic bacteria

Researchers at the University of Leeds say that a type of bacterium which 'eats' iron to create tiny magnets could be used to make larger hard drives and faster connections.

'Nomad planets' could carry bacterial life

Free-flying planets, not anchored to a star, could outnumber stars in the Milky Way by 100,000 to one.

NAND gate built from bacteria

Scientists have taken another step towards biological computing, with the creation of logic gates from gut bacteria and DNA.
