Need To Know
Trump-Xi Summit
President Donald Trump hosted Chinese President Xi Jinping at the White House yesterday, with brief public references to AI. Trump characterized both countries' positions as aligned against the need for regulation prior to the summit; Xi emphasized the need for human control.
The proposal comes amid reports of an OpenAI agent breaching an Australian government website containing Medicare statistics in June. A review found no evidence the agent accessed sensitive information; however, Australian officials criticized OpenAI for informing them of the hack via email three months later. Washington and Beijing officials previously discussed a new safety system that would alert the countries to AI-related threats.
In addition to AI, Xi reportedly pressed Trump to oppose Taiwan independence. Trump previously paused approval of a $14B arms sale to the island in May, an arrangement he characterized as a negotiating tactic. Xi also announced China will send two giant pandas to Atlanta in a diplomatic gesture.
Data Center Headwinds
Oracle invoked a legal provision yesterday to shield it from financial responsibility if regulatory setbacks and local opposition delay the 2028 opening of a $165B New Mexico data center, raising doubts about the viability of AI infrastructure deals. Shares closed down 3.5%.
Project Jupiter—a campus larger than New York's Central Park—would train AI models using as much power as about 1.8 million homes. But state officials have repeatedly denied the permit for a critical natural gas pipeline, citing potential greenhouse gas emissions and dwindling water supplies. The state's largest reservoir is at about 1.4% capacity, its lowest since 1971 (see photos), and data centers can require millions of gallons daily to prevent overheating. Oracle, however, says its closed-loop cooling system will limit 15-year net consumption to the equivalent of nine average US households.
Americans' views of data centers have grown increasingly negative, with roughly 60% saying they would be uncomfortable with a new one in their area. See if there are campuses near you.

Elephants' Forest Pharmacy
Wild elephants in Kenya have been seen using nearly 40 plants and materials for potential medical purposes, a new study found. The observations appear to place the animal in the ranks of chimpanzees, bottlenose dolphins, some birds, and insects.
Researchers interviewed locals near Mount Elgon, including wildlife scouts and rangers. They shared observations of elephants turning to local plants, clays, and soils with known therapeutic applications. Female elephants were observed mixing plants with breast milk before administering the concoction to their young as a form of immunization. Some plants cited are known to aid digestion, improve appetite, or soften stools.
Observation of animals’ medicinal knowledge (a field known as zoopharmacognosy) has a long history. The first story suggesting elephants’ medical knowledge dates back to Claudius Aelianus’ second-century writings, in which he claims an elephant wounded by spears and arrows heals after consuming the flowers and oil of an olive tree (see “18”).
