The year 2021 marks the 100th anniversary of a fundamental discovery that's taught in every biochemistry textbook. In 1921, German physician Otto Warburg observed that cancer cells harvest energy from glucose sugar in a strangely inefficient manner: rather than "burn" it using oxygen, cancer cells do what yeast do they ferment it.
Deadly Bacteria Could Be Sharing Antibiotic Resistance Faster Than We Thought
22 JANUARY 2021
Antibiotics have saved countless lives over the decades. Yet to the pathogens they kill, antibiotics are an ancient foe, one they are already adept at fighting.
It turns out the spread of antibiotic resistance might not be as constrained as we assumed, giving more species far easier access to antibiotic resistance than previous models would have us believe.
The findings come from a study carried out by bioinformatics researcher Jan Zrimec from Chalmers University of Technology in Sweden, which looked for signs of mobility among elements of DNA called plasmids.
Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans.
