Researchers Link Protein to Tumor Growth

Johns Hopkins Medicine

Johns Hopkins researchers working on mice have discovered a protein that is a major target of a gene that, when mutated in humans, causes tumors to develop on nerves associated with hearing, as well as cataracts in the eyes.

Live Imaging Puts New Light on Stem Cell Division

University of Oregon

A long-held assumption about asymmetrical division of stem cells has cracked. Researchers at the University of Oregon report that the mitotic spindle does not act alone -- that cortical proteins help to position a cleavage furrow in the right location.

Explaining “How & Why” Cancer Cells Eat Us Alive

Thomas Jefferson University

Four key studies now propose a new theory about how cancer cells grow and survive, allowing researchers to design better diagnostics and therapies to target high-risk cancer patients. These studies were conducted by a large team of researchers at Thomas Jefferson University’s Kimmel Cancer Center.

Bacteria Make Thrift a Habit

University of Michigan

In these lean times, smart consumers refuse to pay a lot for throwaway items, but will shell out a little more for products that can be used again and again. The same is true of bacteria and other microbes, researchers at the University of Michigan have learned.

Materials Scientist Seeks Dwarfism Clues in a Cell’s Membrane

Johns Hopkins University

A common form of dwarfism is caused by a single genetic mutation. If a scientist could figure out precisely how this errant protein causes trouble, then a way to prevent the condition might be found. Sounds like a job for a biologist. But what about an engineer?

Researchers Discover New Mechanism Behind Cellular Energy Conversion

Mount Sinai Health System

Researchers from Mount Sinai School of Medicine have enhanced our understanding of the mechanism by which cells achieve energy conversion, the process in which food is converted into the energy required by cells. This groundbreaking research helps scientists gain atomic-level insight into how organisms synthesize their major form of chemical energy.

Scientists Closer to Finding What Causes the Birth of A Fat Cell

Ohio State University

Just what causes the birth of a human fat cell is a mystery, but scientists using mathematics to tackle the question have come up with a few predictions about the proteins that influence this process.

RNA Snippets Control Protein Production by Disabling mRNAs

Whitehead Institute for Biomedical Research

Short pieces of RNA, called microRNAs, control protein production primarily by causing the proteins’ RNA templates (known as messenger RNA or mRNA) to be disabled by the cell, according to Whitehead Institute scientists.
