All art is political in the sense that all art takes place in the public arena and engages with an already existing ideology. Chinese artist, Ai Weiwei, offers an important contemporary example. The news that Chinese artist Ai Weiwei has been detained by authorities has prompted significant concern. Ai Weiwei has ben arrested by the Chinese authorities.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Metastasis is the leading cause of breast cancer-related death, but traditional Chinese medicines such as Aiduqing (ADQ) can help prevent it. ADQ is known to target caveolin-1, CXCL1-mediated autophagy, and matrix metalloproteinase-related epithelial-mesenchymal transition, but it remains unclear whether it also modulates tumor-associated macrophage (TAM)/CXCL1 activity to remodel the tumor microenvironment. To find out, researchers recently examined the effects of ADQ in mice and cultured cells. In mice, ADQ significantly reduced xenograft tumor growth and lung metastasis without causing toxicity. ADQ also remodeled the immunosuppressive tumor microenvironment. Mechanistic studies revealed that ADQ reduced CXCL1 expression and secretion from TAMs to suppress CD4+ T cell chemotaxis and Treg differentiation, thus increasing CD8+ T cell cytotoxicity..."

This designed instruction looks to provide students with the tools they need to become an active participant in reading and writing. The specific focus of this one-hour OER module will be to aid learners in determining main ideas and supporting details in statements and paragraphs. Learners will be able to understand the main idea of a paragraph and identify the supporting details that promote the main point.

Aileen Cole Stewart became one of the first African American women to serve in the Army Nursing Corps.

This resource is from a collection of biographies of famous women.

Jason Allen offers a comparative discussion of two important Caribbean poets and playwrights, Aime Cesaire and Derek Walcott, to emphasize the impact of Caribbean literature upon the postcolonial world. By using biographical and historical detail to support his analysis of some of Cesaire and Walcott's key texts, Allen offers insight into what it means to be a Caribbean writer - looking back to a colonial past, and forward to a global future. This audio recording is part the Interviews on Great Writers series presented by Oxford University Podcasts.

Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.

This research seeks to analyze air cargo hubbing and air cargo operations in Hong Kong International airport and the Leipzig/Halle airport both of which have been awarded numerous times due to their excellent service delivery to their customers and efficient handling of air cargo. The Hong Kong international airport has been rated the busiest airport for worldwide air cargo since 1996. 1n 2013, Hong Kong international airport handled 4.12 million tonnes of freight. The airport covers an area of 1,255 hectares. It has a total of 66 boarding gates with 66 jet bridge gates and seven virtual gates. Leipzig/Halle airport moved more than 887,000 tonnes of cargo in the year 2013. It has been ranked number 2 of all German cargo airports and among the 10 best in Europeans cargo airports. The airport offers a variety of services including airfreight and airmail, warehouse and documentation, perishables, pharma handling and customs clearance among others. Leipzig/Halle airport has presented itself as a reliable air transport and logistics industry. Located at the heart of the German logistics section it has proved itself competitive enough to enter the ever growing markets of East Europe and Asia.

This STEM challenge can be used during an air unit. Students work together in groups to create a parachute for a lego person. Students are able to find ways to best maximize air resistance. The students need to find the best way to increase the time that the lego person stays in the air when dropped from the second floor to the first floor.

This lesson plan engages students in a real-life exploration of climate change as it is affected by greenhouse emissions from vehicles. The aim of this activity is for students to realize the impact of vehicle use in their family and to give students the opportunity to brainstorm viable alternatives to this use.

This is a series of activities demonstrating that air has mass, takes up space, and can exert a force on objects enough to lift them.

By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
