Scientists in the Philippines have found a small but important radioactive signal moving through the West Philippine Sea. The discovery shows how human nuclear activity can affect oceans far beyond its original source. While the finding sounds alarming at first, experts say there is no immediate danger to people or marine life. What Did Scientists Discover? Researchers analyzed 119 seawater samples collected from different parts of the West Philippine Sea. They detected higher-than-normal levels of iodine-129, a radioactive isotope linked only to nuclear activity. The concentration was about: This makes the finding scientifically meaningful, even though the levels remain very…

Solving a Key CRISPR Problem CRISPR is powerful because it can cut DNA with precision.But until now, it had one big flaw it didn’t always know when to stop. That may have just changed. Why CRISPR Staying Active Is a Problem CRISPR works like molecular scissors. Once turned on inside a cell, it can: This is called off-target damage, and it’s a major safety concern. The New Discovery: A Built-In Off Switch Researchers have created a smart solution. They designed a tiny protein cap that attaches to CRISPR after it finishes editing. Once attached: It’s like putting a cover on…

A Solution to an Awkward Human Problem Everyone deals with gas.But the smell? That’s what makes it uncomfortable. A French inventor decided to do something about it with science.
