Parents don’t pick favorites, at least if you’re a Magellanic penguin
Researchers at the University of Washington wanted to know how Magellanic penguin parents in South America balance the dietary demands of multiple chicks. As they report in a paper published Jan. 23 in the journal Animal Behaviour, when a Magellanic penguin parent returns to its nest with fish, the parent tries to feed each of its two chicks equal portions of food, regardless of the youngsters’ differences in age or size.

The number of single male Magellanic penguins is rising at this breeding colony. Here’s why.
Female Magellanic penguins are more likely to die at sea as juveniles, which has caused a skewed sex ratio of nearly three adult males to every female, as well as population decline of more than 40 percent since 1987 at one of their largest breeding colonies — Punta Tombo in Argentina.
How economic theory and the Netflix Prize could make research funding more efficient
In a paper published Jan. 2 in PLOS Biology, two scientists at the University of Washington and North Carolina State University use the economic theory of contests to illustrate how the competitive grant-application system has made the pursuit of research funding inefficient and unsustainable — and that alternative methods, such as a partial lottery to award grants, could relieve pressure on professors and free up time for research.

High CO2 levels cause plants to thicken their leaves, which could worsen climate change effects, researchers say
When levels of carbon dioxide in the atmosphere rise, most plants do something unusual: They thicken their leaves. Now two University of Washington scientists have shown that this reaction by plants will actually worsen climate change by making the global “carbon sink” contributed by plants was less productive.

Burst of morning gene activity tells plants when to flower
For angiosperms — or flowering plants — one of the most important decisions facing them each year is when to flower. It is no trivial undertaking. To flower, they must cease vegetative growth and commit to making those energetically expensive reproductive structures that will bring about the next generation. Knowledge of this process at the…

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