Researchers at the University of Illinois at Urbana-Champaign and the Shenyang National Laboratory for Materials Sciences in China have developed a new catalyst that uses visible light to disinfect bacteria and viruses. The new process – which works in either ...

This digitally-colorized scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, ...

An international team of researchers has successfully developed an artificial leaf that can convert sunlight into energy. The team firstly simulated the extremely efficient bacteria light antennae by modifying chlorophyll from an alga. Using the alga’s properties, the ‘artificial leaf’ ...

Scientists from the Weizmann Institute in Israel, led by Prof. Yitzhak Pilpel, have recently shown that bacteria can anticipate certain future events in their environment and prepare for the upcoming changes. According to the scientists, these findings do not only ...

Scientists at the Agricultural Research Service (ARS) and North Carolina State University (NC State) have developed cooperatively a new “green” technology which could lead to clean production of hydrogen from nitrogen-fixing bacteria. Thermotoga maritima (green/yellow rods) growing in co-culture with ...

It has been long thought that normal gut bacteria were involved in colon cancer, but the exact mechanism was not clear. Now, scientists from the USA have uncovered a process in which a molecule produced by a common gut bacterium ...

Novartis, an international drug company, has recently developed a vaccine against the meningococcal B strain. This is the first vaccination to be developed for this often deadly disease that usually affects young children and infants. This new vaccine has the ...

Bacterium is known to be a single cell creature. However, a mass of bacteria can create ‘biofilm’, a layer of bacteria acting together. Some bacteria must be present in biofilm in order to execute some of its features, especially pathogenesis ...

The resistance of bacteria to antibiotics makes the bacteria increasingly dangerous. Bacteria are capable of changing their genes in a random manner, possibly creating new proteins that are resistant to certain types of antibiotics. The problem worsens when you consider ...

A research team from Japan was able to store data on the DNA of a bacteria. Although this breakthrough doesn’t seem to have any immediate applications it might be an important step in the development of future biological computers. Biological ...
