Since the introduction of antibiotics in World War II, doctors have prescribed courses of treatment that typically ran longer than necessary. Bacterial resistance is forcing a reevaluation, shortening courses sometimes to just a few days and even prompting doctors to advise not using all pills if patients feel better.

Antibiotic resistance has left some serious infections with only one defense and the development of new antibiotics has slowed to a crawl, but a study in the journal Nature Microbiology reveals that scientists have found an entire new family of antibiotics in soil. Researchers say the new antibiotics kill a variety of bacteria, including MRSA, that are mostly resistant to current antibiotics. However its likely to take years before the find can be turned into an effective treatment.
We’ve reported on sibling abuse in the past and now a study in the journal Psychological Medicine shows that it can lead to mental illness later. Researchers say people who were bullied by a brother or sister are up to three times more likely than other children to develop schizophrenia, bipolar disorder, or other psychotic disorders by age 18. Kids who are also bullied at school are four times more likely to develop mental illness.
And finally, babies crawling on the floor, especially on carpeting, kick up a lot of bacteria, dirt, pollen, and other biological bits and they breath a lot of that in. In fact, a new study in the journal Environmental Science and Technology shows that crawling babies inhale four times what an adult would when they walk across the same floor. But scientists say its not necessarily a bad thing, exposure to allergens and microbes in infancy helps babies develop immunity and may reduce the chances they develop asthma and allergies later on.
Antibiotic resistance may mean some infections are untreatable in the future. To combat this bacterial evolution, new federal rules went into effect on January 1 that restrict use of antibiotics in food animals, where the majority of US antibiotics are consumed. Critics worry the rules don’t go far enough. Experts on both sides of the issue discuss.
