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.

You may need to rethink your drink. A study in the journal Alzheimer’s and Dementia shows that excess sugar, especially the fructose in soda, may damage your brain. People who drink a lot of sugary beverages are more likely to have a poor memory, a smaller overall brain volume, and a significantly smaller hippocampus, a part of the brain that’s important for learning and memory. But researchers say don’t reach for lo-cal soda. Another study in the journal Stroke, shows that people who drink diet soda are nearly three times as likely to have a stroke and develop dementia as those who don’t drink diet soda.

Courses that teach mindfulness and meditation help women, but a new study shows they don’t help men at all. The study in the journal Frontiers in Psychology shows that while women are more prone to depression and downcast mood overall, learning mindfulness significantly helps them overcome it. However, men are mostly unaffected.

And finally, where a baby’s born makes a big difference in how much they cry. A study in the Journal of Pediatrics finds that on average, babies cry about two hours a day their first few weeks of life. Over three hours per day is officially a colicky baby. And you’ll find more of them in England, Canada and Italy than anywhere else. About a quarter to a third of babies there cry more than three hours a day. The lowest percentages were in Denmark and Germany, where only about five percent of babies spend so much time crying.
