Need To Know

CNN's Strategic Pivot

CNN is cutting about 100 jobs, nearly 3% of its workforce, as CEO Mark Thompson yesterday unveiled a new digital strategy for the company amid declining TV viewership and revenue.


In a memo to staff, Thompson outlined his plan to release a video-heavy subscription product this year through CNN.com as well as paywalled lifestyle content. The announcement comes two years after the abrupt launch—and shuttering—of CNN+, its subscription streaming service. Last year, the company released CNN Max, a live news streaming platform available through parent company Warner Bros.' Max.


For years, CNN's prime-time viewership ratings have declined, trailing Fox News and MSNBC. Profit last year fell below $1B for the first time in years as advertising revenue in early 2023 dropped almost 40% from the year before. CNN's struggles come amid a broader trend in news consumption habits; today, a majority of Americans get at least some of their news through digital products.


Brittle Bone Breakthrough

Scientists have solved a long-standing mystery about how new mothers retain bone strength during breastfeeding, according to a new study. The results may lead to treatments to help injuries heal more quickly and prevent bone diseases in the general population.


The high nutritional demands of milk can deplete bones of essential calcium-based minerals during lactation. Because estrogen, which typically helps promote healthy bones (see overview), drops in the postpartum period, it was unclear how new mothers maintain near-healthy bone density. The study found that a hormone produced exclusively during breastfeeding—known as CCN3—jumps in to take the place of estrogen, triggering bone formation throughout the body.


Although CCN3 is only produced by new mothers, introducing it to any mouse—young or old, male or female—strengthened and promoted bone growth. Researchers hope the findings may one day help treat osteoporosis, which affects more than 200 million people globally. 


Tariffs, Tightened

The White House yesterday released new rules strengthening tariffs on metals routed through Mexico. The rules build upon former President Donald Trump’s 2018 tariffs, which set a 25% tax on steel imports and a 10% tax on aluminum imports.


Mexico won an exemption to the tariffs in 2019; under the new rules, however, companies shipping steel and aluminum from Mexico will have to prove their origin. Officials say 13% of steel and 6% of aluminum imported from Mexico originate from outside of North America, including from China, which produces half of the world’s steel. The announcement comes after the Biden administration raised tariffs on $18B of Chinese imports earlier this year. Goods targeted included electric vehicles, solar panels, semiconductors, syringes, and medical gloves.


The announcement comes as the value of US-China trade has soared in recent decades, with imports surpassing $420B last year, up more than 300% from the turn of the century. Last year's imports nonetheless represented a 20% drop from 2022, as tariffs narrowed the trade deficit with China.
