Scientists discern new antibiotics resistance mechanism to peptide antibiotics
Tue, 20 Mar 2018 14:13:29 EDT
In a recent study, a group of scientists reveals both the widespread distribution and broad-spectrum resistance potential of D-stereospecific peptidases, providing a potential early indicator of antibiotic resistance to non-ribosomal peptide antibiotics.

Excitations: First steps of photosynthesis

Photosynthesis has driven life on this planet for more than 3 billion years -- first in bacteria, then in plants -- but we don't know exactly how it works.

Continuously killing bacteria on coated stainless steel -- add bleach to recharge
Tue, 20 Mar 2018 08:44:00 EDT
Stainless steel is the gold standard for kitchen appliances and cookware, but bacteria can grow on these surfaces, contaminating food. Current coatings available on the market are pricey and potentially harmful, so scientists have now developed an affordable specialized polymer coating for such surfaces that they can recharge with bleach treatments.

Tiny gels sop up intestinal toxins

Bacterial infections that target the intestine can cause conditions that range from uncomfortable to deadly. While it's easy to blame the bacteria, it's actually the toxins the bacteria produce that trigger inflammation, diarrhea, fever and cramps. Researchers now report the development of a microgel scavenger that targets toxins instead of bacteria.
