Scientists examine how a gut infection may produce chronic symptoms
For some unlucky people, a bout of intestinal distress like traveler’s diarrhea leads to irritable bowel syndrome. Recent discoveries have given scientists a better idea of how this happens, and potential leads for new treatments.
New clues about why a universal flu vaccine is so elusive
To scientists' surprise, the immune system develops its response to each virus variant mostly from scratch, instead of building on what it has already learned.
Study pinpoints rare genetic change that may boost risk of HPV-related illness
The human papilloma virus is usually kept in check by the immune system, but scientists identified a genetic variant that makes some infected children prone to developing warts in the throat.
Findings shed new light on why Zika causes birth defects in some pregnancies
Researchers have shown that antibodies against Zika might be involved in causing birth defects in babies born to infected women. The findings might provide important caveats for the development of a vaccine.
To curb infection, bacteria direct their defenses against themselves
To fight off invading viruses, bacteria have evolved a slew of creative defense tactics. New research shows that in some cases, microbes go to great lengths to keep an infection from spreading, even destroying bits of their own genetic material.
New study reveals gut segments organized by function, and opportunities for better drug design
New findings provide insights about how the intestine maximizes nutrient uptake, while at the same time protecting the body from potentially dangerous microbes.
Researchers find genetic link to tuberculosis
Rockefeller scientists have identified a genetic condition that makes people prone to developing tuberculosis. In a British population, they found that the condition underlies one percent of cases of the disease—a finding that may ultimately lead to new treatment options.
Gene-editing technique opens door for HIV vaccine
Researchers successfully modified immune cells to produce antibodies that fight HIV. This strategy could eventually be used to develop a vaccine against the virus, among other conditions.
Lysin therapy offers new hope for fighting drug-resistant bacteria
Increasingly, bacteria do not succumb to antibiotics. Rockefeller researchers have developed a new class of antimicrobial drug, lysin, with one compound showing promising results in a clinical trial—suggesting that an alternative to antibiotics may be on the horizon.
Study explains how geckos gracefully gallop on water
Geckos are amazingly agile. In addition to running across land and up trees, the animals can prance across the surface of water. A new study reveals how they do it.
