Study seeks to answer whether effects of 'abortion pill' can be reversed
- ScienceDaily
- 19/12/5 23:13
Women who initiate medical abortion but opt to stop in the middle of treatment may be at risk for serious blood loss, a study finds. Researchers found this is true even for women who use an experimental treatment that claims to 'reverse' the effects of the abortion pill. The study provides important insights into the safety of using high doses of progesterone during early pregnancy to try to stop...

Ratcheting up NBA rookie salaries may incentivize athletes to finish college
Going pro early may be a no-brainer for exceptional, young basketball stars like former Duke freshman and 2019 NBA draft first-pick Zion Williamson. But a study in the "International Journal of Sport Finance" proposes a new salary structure that might entice most other college players considering the NBA to graduate before trying their hand at going pro.

As China rapidly adopts clean energy, use of traditional stoves persists
- ScienceDaily
- 19/12/5 21:53
Old habits are hard to break. A new study of replacement of traditional wood and coal burning stoves with clean energy in China suggests that, without a better understanding of the reasons behind people's reluctance to give up traditional stoves, it will be difficult for policies in China and elsewhere in the world to succeed in encouraging this shift towards clean energy.

A blockchain expert is accused of helping North Korea’s leaders. But what would they want from him?
The North Korean regime appears to see cryptocurrency as a shortcut to economic development.
As China rapidly adopts clean energy, use of traditional stoves persists
Old habits are hard to break.

In the not too distant future, we can expect to see our skies filled with unmanned aerial vehicles delivering packages, maybe even people, from location to location. Researchers are developing 'digital twins' that combine computational models and machine learning to predict vehicle health and enable autonomous decision-making at the edge.

OSIRIS-REx mission explains Bennu's mysterious particle events
Shortly after NASA's OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission's science team revealed that the asteroid could be active, or consistently discharging particles into space. The ongoing examination of Bennu—and its sample that will eventually be returned to Earth—could potentially shed light on why this intriguing phenomenon is occurring.
Science Museum 'hiding dirty money' over £2m Sackler donation

Assistance during the first years of a biology major leads to higher retention of first-generation students
For many young college students, the first years are a time of wonder and excitement and early steps toward long-term goals. These years, for some students, are equally fraught with anxiety, as the realities of rigorous curricula set in alongside feelings of unpreparedness and impostor syndrome. In the STEM fields, this results in roughly 50% of first-year majors leaving their original course of...
