Deciphering chromosomes: Using CRISPR-Cas9 gene editing, researchers in two studies squeezed 16 chromosomes into 1 or 2, Eileen Drage O’Reilly reports. The experiment helps scientists gather knowledge towards a long-term goal of addressing faulty chromosomes that can trigger miscarriages and some genetic disorders.
Record heat: Death Valley, Calif., set a record for the hottest month in U.S. history — and quite likely global history as well. The average temperature at the Furnace Creek observing station was 108.1°F, which beat the old record set just last year in the same location by about a half-a-degree Fahrenheit.
30,000 words on global warming: The New York Times devotes its entire magazine this weekend to one story on global warming. While many are lauding the paper for focusing on this issue so intensely, others are pointing out problems with the story, Henrietta Reily reports.
Science adviser named — finally: After a record wait, President Trump has nominated a science adviser. The choice has been met with relief and widespread support from the science community. Kelvin Droegemeier, a longtime severe weather researcher at the University of Oklahoma, has experience working in the federal science policy sphere.
CRISPR enzyme: Researchers say they’ve discovered the enzyme Cas12a may be more precise and safer than Cas9, in most cases, to use with the gene editing tool CRISPR because it discriminates more strongly against mismatches, Eileen reports.
