A Duke University study has found that cats' inefficient gait is actually an adaptation for stealthy stalking, rather than energy efficiency. This means that while dogs rely on efficient four-footed running to catch prey, cats use a slow and deliberate approach to creep up on their unsuspecting victims.
Entomologist Dave Kavanaugh finds that climate change has altered the habitats of his beloved beetle species, forcing them to seek new rocky patches above tree-line. He documented 85 North American Nebria beetles, many of which were previously unknown or absent due to habitat shifts.

A study confirms climate change is causing thousands of trees and shrubs to die in the Santa Rosa Mountains, with plant species moving up an average of 213 feet as their habitat shifts. This finding has implications for forest management, ruling out air pollution and fire suppression as main causes of plant death.
Researchers discovered that the Douglas-fir tree's wood structure prevents water from being pulled any higher than 350 feet due to air bubble formation. At this height, trees experience drought-like conditions and struggle to transport water, limiting their growth.
The New Zealand mud snail is outcompeting native species, altering food chains and ecosystems in the Great Lakes. Research suggests the snails can survive being frozen for short periods, making control difficult.
A CU-Boulder study using a space-age, low-gravity training machine found it reduced impacts on muscles and joints by nearly half when subjects ran at 50% of their body weight. The G-Trainer, built by Alter-G Inc., was retrofitted with force-measuring technology to quantify its effects.

A fatal mine collapse in Utah's Crandall Canyon coal mine was actually a massive cave-in that covered an area of approximately 50 acres. New calculations reveal the disaster began near where miners were excavating and quickly grew to four times its initially estimated size.
Researchers at University of Washington and Johns Hopkins University propose that shuffling emerged as a precursor to bipedal behavior to conserve metabolic energy. For distances less than 30 feet, shuffling would be efficient, while longer distances would favor all fours.
New research on azhdarchid pterosaurs suggests they were strongly adapted for life on the ground, with features such as long limbs, stiff necks, and padded feet. The study argues that these reptiles were specialized terrestrial stalkers, using their unique anatomy to pick up prey from the ground.
Researchers at the University of Akron discovered that temperature and humidity significantly impact a gecko's ability to stick to glass. The study revealed that under humid conditions, geckos can cling with twice the force as in dry conditions. Conversely, high temperatures reduce their adhesion, making humidity level less crucial.
