Scientists put a lot of effort into uncovering the history of these tiny bits of matter, in the hopes that it will tell us something about the universe, says astrophysicist Marcelo Gleiser.

Imagine you’re visiting your doctor for a checkup. Your doctor takes all the usual measurements like your height, weight, heart rate, and blood pressure, and then tells you she’s going to sequence your DNA.

A scientist cuts a DNA fragment under UV light for DNA sequencing. Image: AP Five years ago, when researchers first discovered that bacterial immune systems could be hijacked to edit DNA in living creatures, it was big news. The technology, called CRISPR, allowed scientists to more easily than ever cut and paste all those As, Cs, Ts, and Gs that make up the base pairs of DNA and encode the world’s living things. With CRISPR, scientists could use genetic engineering to tackle problems from disease to famine. But gene editing with CRISPR is so 2017. Recently, scientists have begun exploring n…

New Whitehead Institute research may prove to be a useful paradigm for targeting diseases caused by abnormal methylation. Credit: Steven Lee/Whitehead Institute Fragile X syndrome is the most frequent cause of intellectual disability in males, affecting one out of every 3,600 boys born. The syndrome can also cause autistic traits, such as social and communication deficits, as well as attention problems and hyperactivity. Currently, there is no cure for this disorder. Fragile X syndrome is caused by mutations in the FMR1 gene on the X chromosome, which prevent the gene’s expression. This abs…
