    Add penis bacteria to the list of HIV risk factors

    Out-of-whack microbes in the vagina can raise HIV risk — and now there’s evidence that the makeup of the penis microbiome matters, too. The greater the number of anaerobic bacteria tucked under the foreskin, the more likely an uncircumcised man is to become infected with the virus, researchers report July 25 in mBio.

    “This mirrors what’s been seen in women, but it’s the first study of...

    Cows produce powerful HIV antibodies

    An unlikely hero has emerged in the quest to fight HIV: the cow. In a first for any animal, including humans, four cows injected with a type of HIV protein rapidly produced powerful antibodies against the virus, researchers report. Learning how to induce similar antibodies in humans may be key to a successful HIV vaccine.

    The antibodies, called broadly neutralizing antibodies, can stop...

    Common drugs help reverse signs of fetal alcohol syndrome in rats

    A common blood sugar medication or an extra dose of a thyroid hormone can reverse signs of cognitive damage in rats exposed in utero to alcohol. Both affect an enzyme that controls memory-related genes in the hippocampus, researchers report July 18 in Molecular Psychiatry.

    That insight might someday help scientists find an effective human treatment for fetal alcohol spectrum disorders,...

    The fight against gonorrhea gets a potential new weapon: a vaccine

    A vaccine against meningitis has an unexpected side effect: It appears to target gonorrhea, too. If confirmed, the results represent the first instance of a vaccine reducing gonorrhea infections.

    After receiving a vaccine aimed at a type of meningitis, people were less likely to contract gonorrhea, scientists report online June 10 in the Lancet. That’s a big deal because worldwide each...

    Drinking sugary beverages in pregnancy linked to kids’ later weight gain

    An expectant mom might want to think twice about quenching her thirst with soda.

    The more sugary beverages a mom drank during mid-pregnancy, the heavier her kids were in elementary school compared with kids whose mothers consumed less of the drinks, a new study finds. At age 8, boys and girls weighed approximately 0.25 kilograms more — about half a pound — with each serving mom added per...

    Getting a flu ‘shot’ could soon be as easy as sticking on a Band-Aid

    DIY vaccination may be on its way. In the first test in adults, a Band-Aid‒like patch studded with dissolving microneedles safely and effectively delivered a dose of influenza vaccine.

    People using the patch had a similar immune response to the flu vaccine as those who received a typical flu shot, researchers report online June 27 in the Lancet. And nearly all of the patch users...

    Latest stats are just a start in preventing gun injuries in kids

    On June 18, 4-year-old Bentley Thomas Koch fatally shot himself in the face. A few weeks earlier, Harmony Warfield, age 7, was shot and killed by her 2-year-old cousin. And teens Shadi Najjar and Artem Ziberov, both on the eve of graduating from high school, died in a hail of gunfire. Stories like these of kids dying from gunshot wounds are devastating, but, sadly, they aren’t an anomaly.

    Bones make hormones that communicate with the brain and other organs

    Long typecast as the strong silent type, bones are speaking up.

    In addition to providing structural support, the skeleton is a versatile conversationalist. Bones make hormones that chat with other organs and tissues, including the brain, kidneys and pancreas, experiments in mice have shown.

    “The bone, which was considered a dead organ, has really become a gland almost,” says Beate...

    Protein in Parkinson’s provokes the immune system

    Bits of a protein that builds up in Parkinson’s disease trigger the immune system, causing it to tag them as foreign invaders.

    In a blood test, immune cells called T cells became activated when exposed to the protein in about 40 percent of Parkinson’s patients in a new study. This autoimmune response may contribute to the progression of the disease, the researchers report online June 21...

    In 1967, researchers saw the light in jaundice treatment

    Light helps premature babies

    Premature babies, who often develop jaundice because of an excess of bile pigment called bilirubin, can be saved from this dangerous condition by the use of fluorescent light.… The light alters the chemistry of bilirubin so it can be excreted with the bile. Exchange transfusion is the usual treatment when jaundice occurs but this drastic procedure carries a...
