Three new drugs stop acute myeloid leukemia in mice, suggesting the treatments will work in people with this deadly blood cancer. (p. 371)
-
A team of veteran hunters of planets outside the solar system has come up with a landmark finding: a Jupiterlike planet orbiting a Sunlike star at a Jupiterlike distance. (p. 371)
-
Scientists have discovered a gene that controls whether flowers lean to the left or the right. (p. 372)
-
Rather than relegate magnetic fields to the usual backup role of data storage for computers, a new microcircuit exploits those fields for computation, possibly leading to cheaper, lower-power chips than traditional electronic ones. (p. 373)
-
Groups of species may persist through major extinction events only to die off in the aftermath. (p. 373)
-
Some people coordinate language use with both sides of their brains, allowing them to retain verbal skills after damage to one side or the other. (p. 374)
-
Reef corals that spawn in great mixed-up soups of many species may be maintaining their diversity because their hybrids are sterile mules. (p. 374)
-
Studies in space can help physicians better understand a disorder in which patients get faint or dizzy while standing. (p. 376)
-
Compared with the snail's-pace processes that normally shape Earth's surface, the impacts of extraterrestrial objects change our planet's geology in a flash. (p. 378)
-
Researchers have developed a way of encapsulating drugs in red blood cells, which can be used to deliver low doses of anti-inflammatory drugs to cystic fibrosis patients. (p. 381)
-
Wood rats may be fumigating their nests with bits of California bay leaves, sprigs that killed flea larvae in lab tests. (p. 381)
-
Researchers have developed a protein that short-circuits allergic reactions in mice and in tissue cultures of human cells. (p. 381)
-
The new farm bill explicitly exempts rats, mice, and birds from coverage under the federal Animal Welfare Act. (p. 381)
-
Scientists studying sediment cores drilled in eastern Virginia say they’ve possibly identified a new clue to the locations of ancient, hidden impact craters: Just look for broken or twisted microbial fossils. (p. 382)
-
When scientists last month tried to revisit an undersea hydrothermal vent first discovered nearly a quarter of a century ago, they found the site desolate, possibly paved by a fresh volcanic eruption. (p. 382)
-
Even though the two Voyager probes launched in 1977 passed the outermost planets in our solar system more than a decade ago, their sensors show that they can't yet outrun the influence of solar flares. (p. 382)
