A recent RNZ analysis of political advertising on Facebook and Instagram revealed an intriguing pattern in who was seeing the ads.

Of more than 500 ads National ran this year, 92 were seen only by men, attracting up to 3.9 million views and costing as much as $21,000. Only one was seen solely by women – for a single day, at a cost of less than $100 – and the party says it didn’t place it.

ACT showed a similar tilt, with 14 ads seen only by men and…The Conversation (Full Story)

If being outside in the heat for even a few minutes felt miserable this summer, imagine what it’s like for herders who are always out walking with their livestock and rarely get a break.

“We have never experienced such hot days,” a woman herder in northern Kenya told our research team in 2024. “It is difficult to [do things] outside [with] the high temperatures.”

Her experience is echoed by herders in both the U.S. and Kenya, where we study health and climate. Our team’s recent data from Kenya suggests…The Conversation (Full Story)
