A new lab machine developed by Iowa State University professor Neal Iverson can simulate key elements of glacier sliding, helping researchers understand how glaciers react to climate change. The machine uses a ring of ice and hydraulic press to apply pressures equal to those beneath a 1,300-foot-thick glacier.
Drilled at 17,598ft above sea level in the Cordillera Blanca mountain range, the ice cores contain a number of insects and plant materials that may have originated from the Amazon Basin. The cores provide an annually resolvable record of climate conditions, allowing researchers to determine past temperatures and precipitation rates.

Orthopaedic surgeon Dr. Michael Pinzur questions the logic behind this decision, arguing that it undermines patient choice and access to reasonable treatment options.
A University of Oregon professor has developed a Green Classroom Toolbox to improve energy efficiency in existing US schools. The toolbox provides evidence-based renovation guidelines that consider both human performance and environmental impacts, aiming to enhance student learning.
Chronic ankle pain is a common issue that may not resolve on its own after an initial injury. Tendon injuries to the peroneal tendons are now recognized as a possible cause of chronic pain. Early diagnosis and treatment can alleviate symptoms, and imaging techniques like MRI or ultrasound can help identify the condition.
A study by David Alexander, John Lynch, and Qing Wang found that consumers are four times more likely to choose an incrementally new product over a really new one. The researchers also discovered that actual purchases were twice as likely for the least-new products as the most-new ones, with the difference increasing over time.
New research suggests Titan, Saturn's largest moon, has a subterranean ocean of hydrocarbons and unusual topography, including mountains with lower elevations than surrounding plains. The findings may help explain the presence of large lakes of hydrocarbons at both poles.

The study found that trained subjects were better at controlling the landing foot and unconsciously changed their gait, reducing the risk of falling.
Researchers at Ohio State University found that people consistently estimated the length of road dashed lines to be only two feet, despite them being 10 feet long. This misperception has implications for traffic safety, as drivers may be underestimating their speed and covering more ground than they think.

A new study found that smaller male redback spiders have a ten-times higher paternity rate than larger males when given an early start. This is because they mature faster and are quicker on their feet, allowing them to compete effectively.
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 new University of Colorado at Boulder study concludes that global sea rise of more than 6 feet is physically impossible by 2100. The team estimates a total sea level rise of roughly 3 to 6 feet, which is still potentially devastating for low-lying coastal areas.
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.
Researchers have designed an RFID testbed that can measure hundreds of radio frequency identification tags simultaneously. The system allows for rapid testing of new antenna configurations and enables the evaluation of different signaling schemes without fabricating new chips or constructing multiple antennas.
