A seaweed-like marine invertebrate contains a molecule that has piqued interest as a drug but is in short supply: Collecting 14 tons of the critters, a type of bryozoan, yields just 18 grams of the potential medicine. Now, an efficient lab recipe might make bryostatin 1 easier to get.
Making more of the molecule could help scientists figure out whether the drug — which has shown mixed...
An imaging technique that freezes tiny biological objects such as proteins and viruses in place so that scientists can peer into their structures at the scale of atoms has won its developers the 2017 Nobel Prize in chemistry.

For Chong Liu, asking a scientific question is something like placing a bet: You throw all your energy into tackling a big and challenging problem with no guarantee of a reward. As a student, he bet that he could create a contraption that photosynthesizes like a leaf on a tree — but better. For the now 30-year-old chemist, the gamble is paying off.
An imaging technique that lets scientists capture 3-D views of proteins, viruses and other molecules at the atomic scale has won its developers the 2017 Nobel Prize in chemistry.
Jacques Dubochet of the University of Lausanne in Switzerland, Joachim Frank of Columbia University and Richard Henderson of the MRC Laboratory of Molecular Biology in Cambridge will share the prize, the Royal...
News in Brief
Six years after the Fukushima nuclear reactor disaster in Japan, radioactive material is leaching into the Pacific Ocean from an unexpected place. Some of the highest levels of radioactive cesium-137, a major by-product of nuclear power generation, are now found in the somewhat salty groundwater beneath sand beaches tens of kilometers away, a new study shows.
Scientists tested for...

After five years on Mars, the Curiosity rover is an old pro at doing science on the Red Planet. Since sticking its landing on August 5, 2012, NASA’s Little Robot That Could has learned a lot about its environs.
Its charge was simple: Look for signs that Gale crater, a huge impact basin with a mountain at its center, might once have been habitable (for microbes, not...
Mums are now a flower of a different color. Japanese researchers have added a hint of clear sky to the humble plant’s palette, genetically engineering the first-ever “true blue” chrysanthemum.
“Obtaining blue-colored flowers is the Holy Grail for plant breeders,” says Mark Bridgen, a plant breeder at Cornell University. The results are “very exciting.”
Compounds called delphinidin-...
Tsutomu Miyasaka was on a mission to build a better solar cell. It was the early 2000s, and the Japanese scientist wanted to replace the delicate molecules that he was using to capture sunlight with a sturdier, more effective option.
So when a student told him about an unfamiliar material with unusual properties, Miyasaka had to try it. The material was “very strange,” he says, but he...
Walls can’t talk, but scientists can now read stories written in their subatomic particles. And that could make it harder to store radioactive material in secret.
Nuclear radiation rearranges the electrons in insulators such as brick, glass and porcelain. So comparing the positions of electrons in atoms at different spots on walls, windows and floors could provide a rough snapshot of...

Caesar’s Last BreathSam KeanLittle, Brown and Co., $28
Julius Caesar could have stayed home on March 15, 44 B.C. But mocking the soothsayer who had predicted his death, the emperor rode in his litter to Rome’s Forum. There he met the iron daggers of 60 senators.
As he lay in a pool of blood, he may have gasped a final incrimination to his protégé Brutus: You too, my son? Or maybe...
