Newswise — Standard genetic sequencing approaches can tell you a lot about the genetic makeup and activity in a sample, like a piece of tissue or drop of blood. But they don’t tell you where specific ...

Researchers at California NanoSystems Institute at UCLA, Stockholm University and Uppsala University are working on a smartphone-based microscope in hopes of developing a cost-effective and accessible ...

Scientists often describe life as a series of chemical reactions. Pallav Kosuri, Ph.D., describes life as movement. Chemical reactions are how you drive the movement of atoms, proteins, cells and ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

A record player-like microscope and computer simulations solve a longtime mystery, showing that metal ions bridge DNA strands that would normally repel.

Joshua Weinstein spent hours in graduate school pulverizing zebrafish in a blender. That was a normal first step toward sequencing the fish’s genes, but it had a high “ick” factor — and he felt like ...
