Researchers model how ‘publication bias’ does — and doesn’t — affect the ‘canonization’ of facts in science

a bacterium

In an article published Dec. 20 in the journal eLife, researchers present a mathematical model that explores whether “publication bias” — the tendency of journals to publish mostly positive experimental results — influences how scientists canonize facts. Their results offer a warning that sharing positive results comes with the risk that a false claim could be canonized as fact. But their findings also offer hope by suggesting that simple changes to publication practices can minimize the risk of false canonization.

UW researcher pursues synthetic ‘scaffolds’ for muscle regeneration

Miqin Zhang, a professor of materials science and engineering at the University of Washington, is looking for ways to help the body heal itself when injury, disease or surgery cause large-scale damage to one type of tissue in particular: skeletal muscle. Her goal is to create a synthetic, porous, biologically compatible “scaffold” that mimics the normal extracellular environment of skeletal muscle — onto which human cells could migrate and grow new replacement fibers.

A tumor next to a tooth.

University of Washington paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.

For the first time, scientists catch water molecules passing the proton baton

Water conducts electricity, but the process by which this familiar fluid passes along positive charges has puzzled scientists for decades. But in a paper published in the Dec. 2 in issue of the journal Science, an international team of researchers has finally caught water in the act — showing how water molecules pass along excess charges and, in the process, conduct electricity.

A University of Washington study is the first to broadly examine the ecological and financial impacts of seafood mislabeling. The paper, published online Nov. 2 in Conservation Letters, finds that in most cases, mislabeling actually leads people to eat more sustainably, because the substituted fish is often more plentiful and of a better conservation status than the fish on the label.
