Ancient warrior remains belonged to 13-year-old girl

Remains found in a 2,600-year-old Scythian sarcophagus buried with several weapons belong to a 13-year-old girl, according to DNA analysis described in Stratum Plus. "That means we can say with some probability that [Scythian] girls have also participated in hunting or military campaigns," says study author Varvara Busova.

Treatment target identified for leukemia stem cells

Australian scientists are studying the potential for using an antibody to block interaction of the RSPO3 and LGR4 molecules and prevent self-renewal of leukemia stem cells, according to a study in the journal Cancer Cell. "Leukemia stem cells have their own protective mechanisms that make them resistant to anticancer drugs," said researcher Jenny Wang of the Children's Cancer Institute in Australia.

Plant-based diet may reduce gestational diabetes risk

Women who had the most healthful plant-based diet before pregnancy had a 30% lower risk of gestational diabetes, compared with those who had the least healthful plant-based diet, according to a study presented at the virtual American Diabetes Association's Scientific Sessions. "It is crucial to identify novel modifiable risk factors that we can act on to prevent gestational diabetes," said researcher Frank Qian, M.D.

Europa's layers may help in search for life

Jupiter's moon Europa got enough heat to create a dense layered interior through differentiation, which may be why the icy moon has a subsurface ocean, according to findings presented at the virtual Goldschmidt conference. Researchers say the data may help them learn more about the possibility of life on other worlds.

UK researchers awarded $2.7M for COVID-19 drug research

The British research group AGILE received a $2.7 million grant from the nongovernmental organization Unitaid to identify other drugs aside from the ones already being tested that could treat COVID-19 in light of the possibility that the first wave of treatments does not prove to be beneficial to this patient population.

Black female scientists not represented in textbooks

Female scientists overall and Black female scientists in particular are not well represented in common biology textbooks in the US, according to findings published in Proceedings of the Royal Society B: Biological Sciences. Of the 1,000 scientific names listed in the seven undergraduate texts reviewed, 13% were women and 6.7% were people of color, with researchers unable to find any references to a Black female scientist in any biology textbooks they reviewed.

How Does Discipline Integration Help Research?

"We are in this together," people say about our collective distancing efforts to stop the spread of the new coronavirus. Just as the current physical distancing disrupts our natural state of work, higher education has been experiencing a longer period of distancing, one of discipline distancing. The arts, humanities, science, mathematics, and engineering studies have been more specialized and disconnected. Sigma Xi has devoted its 2020 Annual Meeting and Student Research Conference to symposia that illustrate the benefits of interdisciplinary research collaborations and share best practices for carrying them out.

Submit Your STEM-Related Art or Film by July 31

Sigma Xi is bringing back the STEM Art and Film Festival! After it's debut last year, the festival will continue to be the final event of our Annual Meeting and Student Research Conference and take place for the public on November 8 in Alexandria, Virginia. All scientists, artists, engineers, and filmmakers are invited to submit their work by July 31. Visual and performing arts related to science, technology, engineering, and math (STEM) research and education are welcome.
