The Lasker Awards, which honor fundamental discoveries and clinical advances that improve human health, were given on Thursday to scientists for discovering hidden complexity in cells, new states of biological matter, and a potent treatment for cystic fibrosis.

The prizes are named for Mary and Albert Lasker. Ms. Lasker was an advocate for medical research, and her husband is sometimes referred to as the father of modern advertising. The prizes are among the most prestigious in medicine, and scores of Lasker winners have gone on to receive the Nobel Prize. Recipients in each category share a $250,000 prize.

“Many people think they are a miracle that saved Millions of lives,” Mr. Trump wrote on Truth Social. “Others disagree!”

In “The Descent of Man,” published in 1871, Darwin argued that humans arose from apes. And one of the most profound changes they underwent was turning into upright walkers.

The pygmy sea horse is an inch-long fish that lives on corals in the Pacific. The corals, fan-shaped and knobby, are venomous, yet the sea horse can safely wrap its tail around a branch to feed on tiny animals passing by.

Some species of pygmy sea horse are pink, others are yellow, each a perfect match to the species of coral on which it lives. The sea horse also has knobs on its body to match the size and spacing of the knobs on its corals. Instead of the typical sea horse snout, the pygmy sea horse has a face like a pug; its snout resembles yet another coral knob.

For more than 260 years, scientists have consider giraffes a single species. Giraffa camelopardalis, as it was long known, existed across thousands of miles of African grasslands and woodlands.

But scientists now see giraffes differently. One species is officially four, the International Union for Conservation of Nature announced on Thursday. Conservation biologists will now evaluate the status of each; preliminary data suggest three of the species are threatened with extinction.
