Scientists have the power to genetically engineer many types of animals. Most Americans think it’s OK to alter or insert genes in animals and insects — provided it’s done in the interest of human health, according to a poll released August 16 from the Pew Research Center. The findings are similar to those from an earlier Pew survey, which found that a majority of Americans are fine with...
What may be the oldest known solid cheese has been found in an ancient Egyptian tomb.
Made from a mixture of cow milk and either sheep or goat milk, the cheese filled a broken clay jar unearthed from a 13th century B.C. tomb for Ptahmes, the mayor of the ancient city of Memphis, researchers report online July 25 in Analytical Chemistry.
Chemist Enrico Greco, who did the work while...
“The camera never lies” is a thing of the past.
A new computer program can manipulate a video such that the person on-screen mirrors the movements and expressions of someone in a different video. Unlike other film-fudging software, this program can tamper with far more than facial expressions. The algorithm, to be presented August 16 at the 2018 SIGGRAPH meeting in Vancouver, also tweaks...
When pondering the deepest scientific questions — What is time? What is consciousness? Is there life on other worlds? — it helps to have a knowledgeable guide. But not too knowledgeable.
In The Most Unknown, a documentary now available on Netflix, nine scientists perform a research round robin: Each one visits another from an entirely different discipline. Esteemed experts in their own...
A year ago, while news reports focused on the inundation of Houston by Hurricane Harvey, much of the Indian city of Mumbai was also underwater. Both coastal cities, more than 14,000 kilometers apart, had been swamped by extreme rainfall. Deputy news editor Katy Daigle, who had reported from India for seven years for the Associated Press before joining Science News, knew that flooding...08/09/2018 - 07:15 Science & Society, Climate, Earth
When researchers announced last year that they had edited human embryos to repair a damaged gene that can lead to heart failure, critics called the report into question.
Now new evidence confirms that the gene editing was successful, reproductive and developmental biologist Shoukhrat Mitalipov and colleagues report August 8 in Nature. “All of our conclusions were basically right,”...
When it comes to politics, people on one side of the aisle often love to accuse everyone on the other of living in an echo chamber. Liberals hear only what they want to hear, while conservatives read only the news they agree with. (Of course, all those making the accusations are not in bubbles themselves. Oh no, of course not.)
A study published earlier this year suggests that those...
The question of how many died in the aftermath of Hurricane Maria has yet another answer.
Using vital statistics records from hard-hit Puerto Rico, researchers estimate that 1,139 more people died than expected from September 20, 2017 — the day the Category 5 hurricane made landfall — through that December.

Women face an uphill battle in biomedical science, on many fronts. There is bias in hiring and in how other scientists view their research. Fewer women are chosen to review scientific papers. Men still outnumber women at the ivory tower’s highest floors, and of course, women in science face harassment based on their gender. But once the top of the hill is in sight — once a female scientist...

Only a day after the first test-tube baby turned 40, a poll about American’s attitudes toward tweaking unborn babies’ genes reveals the hopes and hesitations of being on the brink of the latest reproductive era.
Americans generally favor gene editing, but only for heading off diseases. Boosting intelligence would be “taking medical technology too far,” survey respondents said. (Not that...
