Phys.org / New modified CRISPR protein can fit inside virus used for gene therapy

Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells. Hongjian ...

Phys.org / Fossil places extinct saber-toothed cat on Texas coast

Important scientific finds don't always come in the biggest, buzziest packages. Sometimes new discoveries come in little ugly rocks. Such is the case of a 6-centimeter-wide, nondescript mass of bone and teeth that helped ...

Phys.org / Historic iceberg surges offer insights on modern climate change

A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs, and the havoc it wrought was on the ocean current itself.

Phys.org / Study shows cuckoos evolve to look like their hosts—and form new species in the process

The theory of coevolution says that when closely interacting species drive evolutionary changes in each other this can lead to speciation—the evolution of new species. But until now, real-world evidence for this has been ...

Phys.org / Misleading COVID-19 headlines from mainstream sources did more harm on Facebook than fake news, study finds

Since the rollout of the COVID-19 vaccine in 2021, fake news on social media has been widely blamed for low vaccine uptake in the United States—but research by MIT Sloan School of Management Ph.D. candidate Jennifer Allen ...
