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.

Hit your head, lose your sense of smell
It's long been known that people who suffer a major concussion can lose their sense of smell temporarily and also develop affective problems, such as anxiety and depression. Now scientists have found that's true even for people who get a minor concussion.

Zhang group identifies gene that may make TNBC cells vulnerable to existing
Certain therapies that have proven effective in treating some types of breast cancers are ineffective for women diagnosed with triple-negative breast cancer (TNBC). In fact, there is limited targeted drug therapy for this type of breast cancer—the most aggressive type, diagnosed in about 20 percent of breast cancer patients.

Buying local? Higher price means higher quality in consumers' minds

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.

Harnessing the power of microbes for mining in space
For centuries, people have done the hard work of mining useful minerals and metals from solid rock. Then, scientists learned how to harness the power of tiny microbes to do some of this labor. This process, called biomining, has become common on Earth.

How to restore a coral reef
New guidelines drafted by a consortium of concerned experts could enable corals to adapt to changing environments and help restore declining coral populations in the Caribbean. The guidelines provide a definitive plan for collecting, raising, and replanting corals that maximizes their potential for adaptation.

Active pharmaceutical ingredients can persist in the environment
Homeowners who rely on private wells as their drinking water source can be vulnerable to bacteria, nitrates, and other contaminants that have known human health risks. Because they are not connected to a public drinking water supply, the homeowners are responsible for ensuring that their own drinking water is safe.

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.

Study identifies cells required for the development of a healthy uterus
Knowledge of the biological processes involved in the development of the uterus is important for understanding uterine health and fertility. A research team led by investigators at Massachusetts General Hospital (MGH) has uncovered important insights on a type of cell that is critical for the formation of a functioning uterus.

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.
