Twitter on Friday published data that appeared to show its workforce was more diverse in 2017, but the way Twitter currently measures diversity makes it hard to tell how much progress the company is actually making. According to Twitter's diversity data, ''underrepresented minorities'' - which Twitter defined as non-white and non-Asian - now make up 12.5 percent of the company's total workforce, up from 11 percent in 2016. But that 12.5 percent includes people who specifically declined to identify their ethnicity on Twitter's internal survey, according to a company spokesperson. That unidentified group makes up 2.9 percent of Twitter's workforce and is being classified as ''underrepresented minorities'' even though this contingent specifically declined to be classified. There is no way to tell what ethnicity they actually are. If you subtract that group from Twitter's list of ''underrepresented minorities,'' it shows non-white and non-Asian employees at Twitter made up just 9.6 percent of the company workforce, a decline from 11 percent in 2016. So while Twitter said its ranks were more diverse last year, that may not actually be true.

A new study finds puzzling national differences: a bigger share of STEM degrees for women in Tunisia than in Sweden . A key tenet of modern feminism is that women will have achieved equity only when they fill at least 50% of the positions once filled by men. In some fields, women have already surpassed that target - now comprising, for example, 50.7% of new American medical students, up from just 9% in 1965, and 80% of veterinary students. But the needle has hardly moved in many STEM fields - such as the physical sciences, technology, engineering and math, in which barely 20% of the students are female. A new study suggests some surprising reasons.

Last weekend global leaders in science, technology and diplomacy gathered at the United Nations and universities around the world for the third Annual International Day of Women and Girls in Science. The overall platform aims to mobilize women in a wide range of science disciplines, contributing to achievement of Sustainable Development Goals and the UN's 2030 Development Agenda. When only 30% of the world's researchers are women, this call for educational awareness and advocacy could not be more important to global public health. In recent years, women's involvement - particularly in leadership roles - in the sciences have varied by region and discipline, and continually shift by sector and generational cohorts. The U.S. in particular has seen positive overall results in the number of women in science, but that's not equally reflected in positions of leadership - or for women of color. In fact, according to the National Center for Education Statistics, as recently as 2016 Black women (2.9%), Latinas (3.6%) and Asian women (4.8%) collectively made up very small portions of those graduating with STEM degrees.

The Scirens, a group of three Hollywood actresses passionate about science, share their commitment to creating new stories for women in STEM with DiscovHER.

The GHC 18 tracks is offering a wide-range of fields for every technical woman. Speakers will participate in presentations, panels, or workshops. GHC is actively looking for and encourage you to submit intermediate and advanced level content. They are also accepting submissions for the Mentoring Circles (formerly Student Opportunity Lab) and the Poster Session.

Computer science is taking off in K-12 schools, fueled in part by hundreds of millions of dollars and aggressive lobbying from the technology industry. Cue the concerned chorus. Is Silicon Valley - currently under harsh scrutiny for its consumer products and services - attempting to reshape public schools to serve its own ends? How are the tech industry's desires and dollars actually shaping what computer science looks like in real classrooms? And given rapid advances in artificial intelligence, will a short-term focus on filling today's tech-sector jobs ultimately backfire? As part of deep dive on the 'Computer Science for All' movement, Education Week explored those questions with a number of heavy hitters in the field.

The Grace Hopper Celebration hosts a Poster Session for individuals to share their latest research in computing. It's a perfect chance to get feedback for those who are not yet at the stage of writing a formal paper or just to gain experience talking at a large conference. Are you interested in speaking at the 2018 Grace Hopper Celebration (GHC 18) in September? Don't miss the chance to learn more about your field, network with new people, and discover how you can further your career.

BRAID Affiliates are institutions that have committed to increasing the diversity of their computing departments, but do not receive funding through the BRAID initiative. Institutions selected to be BRAID Affiliates are invited to participate in BRAID for one year. Affiliates learn best practices from our BRAID schools, and participate in the annual BRAID Summit, which gathers together all the BRAID stakeholders for two and a half days of discussion, ideation, and inspiration.

The only conference dedicated to all the diverse groups that comprise our engineering and computing workforce. The vision of the CoNECD (pronounced, ''connected'') Conference is to provide a forum for exploring current research and practices to enhance diversity and inclusion of all underrepresented populations in the engineering and computing professions including gender identity and expression, race and ethnicity, disability, veterans, LGBTQ+, 1st generation and socio-economic status.

ChickTech is a nonprofit organization dedicated to retaining women in the technology workforce and increasing the number of women and girls pursuing technology-based careers. ChickTech envisions a safe, inclusive, and innovative technology future that includes equal pay, participation, and treatment of women. All proceeds from the ACT-W National Conference go towards providing local high school girls with STEM education programs and spreading ChickTech's reach to create a culture of inclusion for all!
