Stuck on you: Research shows fingerprint accuracy stays the same over time

A groundbreaking study published in PNAS has found that fingerprint recognition accuracy stays the same even after years of aging. Using large-scale data from the Michigan State Police, researchers Anil Jain and Soweon Yoon demonstrated that fingerprints remain stable over time, addressing a long-standing concern in forensic science.

Lovebird has clear sight during rapid turns

Rapidly turning lovebirds execute extremely fast head turns when their wings cover their eyes, shortening blurry phases and maintaining stable vision. This super-fast behavior allows them to make split-second decisions during maneuvers.

Why big dinosaurs steered clear of the tropics

The study reveals that wild climate swings in the tropics made it difficult for large, warm-blooded dinosaur herbivores to survive. The researchers found that wildfires swept the landscape during arid regimes, continually reshaping vegetation available for plant-eating animals.

Return trips feel shorter in hindsight

A study published in PLOS ONE found that participants estimated the length of a round-trip walk as shorter than the outward trip, even when the times were equal. This phenomenon, known as the return trip effect, may be related to our perception of time and awareness of the destination.

Career tracking of doctorate holders

A pilot study of post-doctorates and doctorate alumni reveals differences in research outputs, satisfaction levels, and employment continuity between permanent and temporary contract holders. The report also discusses the challenges faced by doctorate holders in finding alternative career paths beyond academia.

From worker to queen at the drop of a gene

Biologists from the University of Leicester have discovered that buff-tailed bumblebees develop into queens or workers based on gene expression. The study found that differentiation is not caused by inherited genetic differences, but rather by distinct expression patterns in adults.

Nonfriction literature

The National Science Foundation has funded a project to develop ultralow-wear composite materials for industrial applications, with the goal of reducing friction and wear costs. The research will explore material structures, composition, processing, and operating conditions to improve tribological performance.

Toward 'green' paper-thin, flexible electronics

Scientists have created a light-emitting, transparent and flexible paper out of biocompatible materials, a significant step towards bendable electronics. The innovation uses wood flour and quantum dots made from zinc and selenium, offering a 'greener' alternative to traditional plastics.

Team science is better science

A groundbreaking report from the National Research Council concludes that team science is increasingly used in scientific research, enhancing innovation and impact. However, resolving the challenges of effective team science requires attention to assembling the right people, training and development, and team leadership.

Professor Matei Ciocarlie wins Young Investigator Program grant for hands-on research

Professor Matei Ciocarlie has received a three-year Young Investigator Program grant to develop collaborative manipulation systems for human-robot teams. His research aims to create novel mechanisms that combine mechanical and computational intelligence, enabling robots to perform versatile tasks in cluttered or occluded settings.

Burmese long-tailed macaque stone-tool use catalogued

Eighty percent of Burmese long-tailed macaques on an island in southern Thailand use stone and shell tools to crack open seafood, employing 17 different action patterns. The study catalogued tool use and action patterns, revealing one-handed hammering for precision striking and two-handed hammering for larger shells.

Caution urged in using measures of students' 'non-cognitive' skills for teacher evaluation, school accountability, or student diagnosis

Researchers warn against using existing measures of non-cognitive skills, such as self-control and grit, for evaluating educators, programs, or diagnosing students. The measures are not yet ready for educational use and may yield misleading results. A multi-method approach to measurement can increase reliability and validity.
