Bacteria

The origin of complex life is delayed

One of the great challenges of paleontology is to know how multicellular life could have sprung up from simple unicellular beings, such as bacteria.

What is infectobesity?

As strange as it may seem, the intestinal flora can be one of the main causes of weight gain. The closest example supporting the association between infection and inflammation is the Helicobacter pylori germ, which causes most stomach ulcers.

Typical Summer Diseases – Infections

Summer, in addition to bringing sun and heat, is also usually accompanied by several typical ailments of this time, favored by the excessive increase in temperatures. These are some of the most frequent:

Non-human DNA found in Ötzi, 'the ice man'

A team of scientists from the EURAC Institute in Bolzano (Italy), as well as several researchers from the University of Vienna (Austria) have discovered non-human DNA in the sample of hip bone that was extracted from the 5,300-year-old mummy found on a glacier in the Alps and named Otzi, the Iceman.

Washing raw chicken increases the risk of food poisoning

What seems like a common custom in any neighbor's house poses a huge risk to our health, according to the United Kingdom Food Standards Agency (FSA).

They create a new type of DNA without a base in nature

A team of researchers from the Scripps Research Institute in California (USA) has succeeded in incorporating new letters into the genetic alphabet after developing a bacterium whose DNA includes two artificial bases that do not exist naturally, thus creating the first semi-synthetic living organism.

They create living materials with bacteria cells

A team of engineers from the Massachusetts Institute of Technology (MIT) has managed to design living materials (biofilms or biofilms) that can incorporate non-living materials such as quantum dots or gold nanoparticles. All from bacterial cells. The work has been published in the journal Nature Materials.

What is Tularemia?

Tularemia, or also called "rabbit fever", is an infectious disease, as dangerous as smallpox or anthrax and common in the northeastern United States, Europe and Asia. The bacterium that causes it is Francisella tularensis and due to its strong environmental resistance (it resists cold at sub-zero temperatures and even bleach), it becomes a threat to public health.
