We are not what we eat when it comes to gut bacteria

When it comes to gut bacteria, we are not what we eat. The types of gut bacteria that populate the guts of primates depend on the species of the host as well as where the host lives and what they eat, says a new study.

The study led by Howard Ochman at Yale University examines the gut microbi... Read More

Atomic snapshot shows how RNA ruled

Using powerful X-rays, researchers have produced an atomic picture of how ribonucleic acid (RNA) molecules interacted in the ancient world.

It is a rare glimpse of the transition from a time when RNA reigned supreme to the present, where proteins carry out the processes essential to life.

Parasites: Learning a Worm-Killer’s Modus Operandi

Researchers have finally discovered how ivermectin, one of the most important worm-killing drugs used in both humans and animals for decades, actually works.

Ivermectin, extracted from a soil fungus in the 1970s, was originally sold under names like Heartgard to deworm pets.

Beginning in 1... Read More

New Bacteria-Killing Light Can Destroy Superbugs With the Flip of a Switch

Sterilization is hands down one of the most important technologies ever developed by mankind, but though we’ve known how to do battle with bacterial pathogens in places like the operating room for decades, superbugs like MRSA and Clostridium difficile persist in hospital environments, often caus...

LEDs kill hospital superbugs

A lighting system that kills bacteria, including superbugs such as MRSA and C difficile, has completed trials at a Glasgow hospital.

The LED technology, which can be used alongside or instead of traditional lighting, continually disinfects the air and exposed surfaces with certain violet wave... Read More

Prokaryotes considered

As a college biology major during the 1970s I was taught that cells in which the genetic material is separated from the cytoplasm by a nuclear membrane – such as those of animals, fungi, plants, and protists – are called eukaryotes. In contrast, the DNA of bacteria is not bounded by such a struc... Read More

Problem-solving bacteria crack sudoku

The appeal of sudoku has spread to the prokaryotic world. A strain of Escherichia coli bacteria can now solve the logic puzzles – with some help from a group of students at the University of Tokyo, Japan.

"Because sudoku has simple rules, we felt that maybe bacteria could solve it for us, as ... Read More

Telltale bacteria could reveal time of drowning

When a fisherman's body washed ashore on Australia's Queensland coast last week, police initially had no way of working out when he had died. "Unless a body is witnessed entering the water, there is no reliable method for determining the length of time that a body has been submerged," says Gemma... Read More

Designer bacteria can heal cracks in concrete buildings

Researchers have designed bacteria that can produce a special glue to knit together cracks in concrete structures.

The genetically modified microbe has been programmed to swim down fine cracks in concrete and once at the bottom it produces a mixture of calcium carbonate and a bacterial glue. ... Read More
