Are we prepared for a new era of field geology on the moon and beyond?

The authors argue that space agencies should prioritize field geology training for all astronauts, including those with advanced degrees in geology. Developing new science operations strategies using emerging technologies will optimize mission productivity and unlock the full potential of scientific research on the Moon, Mars, and beyond.

How pipeline programs can increase diversity in dentistry

A pipeline program called Saturday Academy at NYU College of Dentistry has shown to increase interest in the health professions, particularly dentistry, among underrepresented high school students. The program exposes students to the field through instruction and hands-on learning, mentoring them through the college application process.

Every time the small cabbage white butterfly flaps its wings it has us to thank

A team of researchers, led by Sean Ryan, documents the invasive history of the small cabbage white butterfly, which they attribute to human activities such as trade and migration. The study uses DNA analysis from over 3,000 submitted butterflies to reveal the butterfly's spread across Europe, Asia, Siberia, North America, and New Zealand.

The vagina monocultures

Researchers at Johns Hopkins have developed a universal screening approach for vaginal microbiota transplantation (VMT) donors to ensure only beneficial microbes are transferred. The pilot study found that 35% of participants might be eligible VMT donors, and the success rate may depend on a small number of willing 'super donors'.

Diabetes nearly double for Japanese-Americans

A new study found that Japanese-American adults with a normal body mass index have a significantly higher risk of developing diabetes compared to their non-Hispanic white counterparts. The study revealed that younger respondents, never smokers, and those with higher education levels were less likely to have diabetes.

What the noggin of modern humans' ancestor would have looked like

Researchers created a virtual 300,000-year-old fossil skull with relatively modern features, similar to some fossils only 100,000 years old. The study suggests that the species Homo sapiens arose through hybridization of South and East African populations, contradicting previous theories.

Adolescents with high levels of physical activity perform better in school over two years

A new study from Finland found that adolescents with higher levels of physical activity performed better in school during a two-year follow-up period. However, the results also showed that increasing physical activity did not necessarily result in improved academic performance, and may even lead to lower grades for some participants.

Lasker Foundation announces 2019 Lasker Awards

The 2019 Lasker Awards recognize Max D. Cooper and Jacques Miller for their discovery of the function of B and T cells in the adaptive immune system. The awards also honor H. Michael Shepard, Dennis J. Slamon, and Axel Ullrich for their development of Herceptin, a monoclonal antibody therapy that targets HER2-positive breast cancer.

Do animals control earth's oxygen level?

Researchers from the GLOBE Institute found that massive fluctuations in ocean oxygen levels during the Cambrian explosion were influenced by animal behavior. The discovery suggests that animals may have controlled their own development through adjustments to oxygen levels, shedding light on Earth's 'heartbeat' and its impact on life.
