Good Morning. The WHO says don't panic. The ship is now on the move. We break down the hantavirus outbreak tracking dozens.

Plus, Wall Street's narrowest rally on record, AI that copies itself, and David Attenborough's 100th birthday lesson (forwarded this email? Join 523k readers).

Health agencies on four continents are tracking dozens of passengers who left the MV Hondius cruise ship before a deadly hantavirus outbreak was detected. Three have died, including a Dutch couple and a German national. Several others are sick onboard.

The first death happened April 11. Roughly 30 to 40 passengers disembarked at remote St. Helena two weeks later with no contact tracing. Hantavirus was not confirmed until May 2, in a British passenger now in intensive care in South Africa. Why this isn't the next Covid, according to the WHO.

Singapore, Switzerland, and St. Helena are now monitoring contacts. Some have been told to isolate for 45 days. The World Health Organization says public risk stays low. The strain is the rare human-to-human variant from South America.

The S&P 500 has surged more than 12% since April, but five tech stocks (Alphabet, Nvidia, Amazon, Broadcom, and Apple) account for more than half the gains. UBS says the number of stocks materially driving the index hit a record low of 42 last week, down from a typical 100.

Investors started 2026 betting on a "broadening" rotation into supermarkets, housebuilders, and miners. The Middle East war flipped that. Energy prices spiked, earnings outside tech stalled, and money piled back into AI names. The Philadelphia Semiconductor index is up over 40% since the war started.

Goldman Sachs is now warning that this narrow breadth signals drawdown risk if the tech sector stumbles. Now, only 20 stocks now control 50.8% of the S&P 500.

▲ How concentrated is too concentrated? A historical comparison to 1972 and 1999

Scientists just published the most precise measurement ever of how fast the universe is expanding. A galaxy 3 million light-years away moves from us at 46 miles per second. Double the distance, double the speed.

The number is roughly 10% faster than the standard model of cosmology predicts it should be. That gap suggests something is missing from physics' core theory of the universe, possibly an unknown force tied to dark matter or dark energy.

The expansion is microscopically slow. A football field expanding at this rate would take a million years to grow one centimeter. The bigger problem: the prevailing "heat death" theory of the universe's end may no longer hold.

Sir David Attenborough turns 100 today. The skill that made him the most trusted voice on earth is one most communicators get wrong: he learned to say less.

In one of Planet Earth II's most cinematic sequences (a four-and-a-half-minute snake-versus-iguana chase), Attenborough speaks just 89 words. "Words aren't all that necessary," he has said. "You're just completely held."

Where most narrators push for authority through volume and pace, Attenborough whispers. Where Hollywood actors take three or four days to record narration for a 90-minute film, he records a 50-minute documentary in roughly an hour, in one take.

The lesson for anyone who writes, presents, or sells: trust the material. The voice that resonates isn't the loudest one in the room.

A former YC founder and mother of four under five just rebuilt how parents work, and the lesson applies to anyone with a fragmented schedule.

Jesse Mostipak runs sophisticated AI projects during what she calls "confetti time," the 10-15 minute windows scattered through a parent's day. Instead of waiting for an 8-hour focus block that never arrives, she assigns tasks by voice note and lets agents execute while she's with her kids.

The shift: stop guarding your calendar for the perfect work session. Start matching small tasks to small windows. Five minutes between meetings is enough to delegate, dictate, or kick off a draft.

The real productivity unlock isn't longer focus blocks. It's getting comfortable working in fragments.
