3-D printed pill samples gut microbiome to aid diagnosis and treatment

A research team led by Tufts University engineers has developed a 3-D printed pill that samples bacteria found in the gut—known as the microbiome—as it passes through the gastrointestinal tract (GI). The ability to profile bacterial species inhabiting the gut could have important implications for the diagnosis and treatment of conditions that are affected by the microbiome, according to the researchers.

Mouse, not just tick: New genome heralds change in Lyme disease fight

As Lyme disease increases, researchers have taken a significant step toward finding new ways to prevent its transmission. The experts, who include a pioneer in Lyme disease discovery, have sequenced the genome of the animal carrying the bacteria that causes the illness. The advance by researchers at the University of California, Irvine and colleagues provides a launching pad for fresh approaches to stopping Lyme disease from infecting people.

Study shows extra weight in 60s may be linked to brain thinning years later

Having a bigger waistline and a high body mass index (BMI) in your 60s may be linked with greater signs of brain aging years later, according to a study published by a leading University of Miami neurologist researcher in the July 24, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology. The study suggests that these factors may accelerate brain aging by at least a decade.

Frog in your throat? Stress might be to blame for vocal issues

Glossophobia, or the fear of public speaking, often comes up in lists of greatest fears. Such anxiety can often impact voice control leading to stammering or feeling like there is a "frog in your throat." A researcher from the University of Missouri has found that there is more to vocal issues than just feeling nervous and that stress-induced brain activations might be to blame.

Tobacco-21 laws can lower smoking prevalence in the 18-20 age group

A new study published today by the scientific journal Addiction found that raising the legal age of sale of cigarettes from 18 to 21 in the U.S. was associated with a 39% reduction in the odds of regular smoking in 18- to 20-year-olds who had experimented with cigarettes. The reduction was even greater (50%) in those who had close friends who smoked when they were 16.

Folic acid reduces risk of neural tube defects linked to HIV drug dolutegravir

Dolutegravir is a preferred medication for treating HIV infection, but it recently has been linked to a 6- to 9-fold increase in the risk for neural tube defects among babies born to mothers receiving the drug during early gestation. Researchers at Baylor College of Medicine suspected that folic acid (vitamin B9), which is known to prevent the vast majority of neural tube defect cases, could be a part of the puzzle of dolutegravir's negative side effects.

Study: Fat cells play key role in dangerous transformation of melanoma

Researchers at Tel Aviv University, led by Prof. Carmit Levy and Dr. Tamar Golan of the Department of Human Genetics and Biochemistry at TAU's Sackler School of Medicine, have discovered that fat cells are involved in the transformation that melanoma cells undergo from cancer cells of limited growth in the epidermis to lethal metastatic cells attacking patients' vital organs.

Putting the brakes on lateral root development

There's no organ system in the body that does as much for humans as roots do for plants. Part anchor and part mouth, a plant's root system architecture is critical to its success. But the process of growing new roots is costly to a plant, and there can be diminishing returns.

What motivates people to join—and stick with—citizen science projects?

From searching for extraterrestrial life to tracking rainfall, non-experts are increasingly helping to gather information to answer scientific questions. One of the most established hands-on, outdoor citizen science projects is the University of Washington-based Coastal Observation and Seabird Survey Team, COASST, which trains beachgoers along the West Coast, from California to Alaska, to monitor their local beach for dead birds.

PrEP use high but wanes after three months among young African women

In a study of open-label Truvada as daily pre-exposure prophylaxis (PrEP) to prevent HIV among 427 young African women and adolescent girls, 95% initiated the HIV prevention strategy, and most used PrEP for the first three months. However, PrEP use fell among participants in this critical population during a year of follow-up clinic visits, although HIV incidence at 12 months was low. The preliminary results suggest that tailored, evidence-based adherence support strategies may be needed to durably engage young African women in consistent PrEP use. The study, known as HPTN 082, was supported by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Mental Health (NIMH), both parts of the National Institutes of Health. The data were presented at the 10th International AIDS Society Conference on HIV Science.

Most women use vaginal ring for HIV prevention in open-label study

In an open-label study of women in southern and eastern Africa, a vaginal ring that is inserted once a month and slowly releases an antiviral drug was estimated to reduce the risk of HIV by 39%, according to statistical modeling. In addition, the study found that participants appeared to use the ring more in the open-label study than in a previous clinical trial. These and other results of the HIV Open Label Extension (HOPE) study were presented today at the 10th IAS Conference on HIV Science (IAS 2019) in Mexico City.

Left eye? Right eye? American robins have preference when looking at decoy eggs

Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg placed in their nest by another bird species—or by a devious scientist.
