Beverage consumption a bigger factor in weight

When it comes to weight loss, what you drink may be more important than what you eat, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Researchers examined the relationship between beverage consumption among adults and weight change and found that weight loss was po...

Male crickets with bigger heads are better fighters, study reveals, echoing ancient Chinese text

Observing and betting on cricket fights has been part of Chinese cultural tradition since at least the Sung Dynasty (A.D. 960-1278). This ancient practice has resulted in quite a detailed list of characteristics that Chinese practitioners think make for champion fighters. "Because money was involv...

In the animal world, bigger isn't necessarily better

TORONTO, ON. Shocking new research shows size isn't always an advantage in the animal world, shattering a widely-held belief that bigger is better. Michael Kasumovic, a former University of Toronto Scarborough PhD student, examined Australian Redback male spiders to determine whether the larg...

Plants grow bigger and more vigorously through changes in their internal clocks

AUSTIN, TexasHybrid plants, like corn, grow bigger and better than their parents because many of their genes for photosynthesis and starch metabolism are more active during the day, report researchers from The University of Texas at Austin in a new study published in the journal Nature . Their...

Insects take a bigger bite out of plants in a higher CO2 world

Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plants defenses against leaf-eating insects, according to the report. The University of Illinois study app...

Seismic images show dinosaur-killing meteor made bigger splash

AUSTIN, TexasThe most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago. The Chicxulub crater was formed when a...

Economists: Reduce fish catch now for bigger net profits later

A new and compelling argument for reducing fish harvests the profit motive could persuade world fishers to endure the short-term pain of lower catches for the long-term gain of higher returns for their labor, according to authors of a ground-breaking study on fisheries over-exploitation. They...

Largest ever study of genetics of common disease just got bigger

DNA samples from 120,000 people are to be analysed in a 30 million follow up to last year's Wellcome Trust Case Control Consortium (WTCCC), the largest ever study of the genetics behind common diseases. The seven-fold increase in the number of samples to be analysed will allow researchers to look ...

Why do cold animals make bigger babies?

Reproduction involves a critical decision: Should an organism invest energy in a few large offspring or many small ones? In a new study from The American Naturalist, Michael Angilletta (Indiana State University), Chris Oufiero (University of California, Riverside), and Adam Leaché (University of Ca...

How to grow a bigger brain

Hatchery-reared steelhead trout show increased growth of some parts of the brain when small stones are scattered on the bottom of their tank, according to a new study by researchers at UC Davis. The brains of those young fish were closer to those of salmon reared in the wild, and the fish also show...

Study finds evolution doesn't always favor bigger animals

Biologists have long believed that bigger is better when it comes to body size, since many lineages of animals, from horses to dinosaurs, have evolved into larger species over time. But a study published this week by two biologists at the University of California, San Diego in an early online ed...
