Personal Experience of Climate Change May Influence Opinion of It

Perceiving Climate Change

A study from scientists at Yale University examined the extent to which 91,000 individuals in 89 countries on five continents detected recent changes in average local temperatures, finding that public opinion of climate change may shift in response to the personal experience of climate change. Human beings around the world are observing and accurately detecting […]

First USA Alzheimer’s Patient Implanted with Brain Pacemaker

The First Brain Pacemaker To Treat Alzheimer's

A new study that involves implanting a pacemaker in the brain is underway to determine if deep brain stimulation (DBS), the same technology used to successfully treat about 100,000 patients worldwide with movement disorders, can be used to treat Alzheimer’s patients. Columbus, Ohio – During a five-hour surgery last October at The Ohio State University […]

Discovery of ‘Bird-Dinosaur’ Eosinopteryx Challenges Bird Evolution Theory

Eosinopteryx

Findings related to the newly discovered ‘bird-dinosaur’ Eosinopteryx suggest that the origin of flight was much more complex than previously thought. The discovery of a new bird-like dinosaur from the Jurassic period challenges widely accepted theories on the origin of flight. Co-authored by Dr Gareth Dyke, Senior Lecturer in Vertebrate Palaeontology at the University of […]

Mathematical Model May Explain What Dark Matter Consists Of

A Revolutionary Theory of Dark Matter

University of Oslo’s leading theorist in astroparticle physics, Are Raklev, has launched a model that explains what dark matter may consist of and how one can discover the invisible particles experimentally. Astrophysicists have known for the last 80 years that most of the universe consists of an unknown, dark matter. The solution to the mystery […]

Scarecrow Gene May Lead to New Varieties of Staple Crops with Higher Yields

A Cross Section of a Mature Maize Leaf

Scientists at Cornell University believe that the Scarecrow gene – the first gene discovered to control Kranz anatomy, which leads to more efficient photosynthesis – may lead to new varieties of staple crops with higher yields. With projections of 9.5 billion people by 2050, humankind faces the challenge of feeding modern diets to additional mouths […]

Controlled Graphene Crumpling Used as Artificial Muscle Actuators

Crumpled Graphene

By developing a method to reversibly control the crumpling and unfolding of large-area graphene sheets, researchers at Duke University were able to demonstrate that crumpled graphene–polymer laminates can be used as artificial-muscle actuators. Durham, North Carolina – Duke University engineers are layering atom-thick lattices of carbon with polymers to create unique materials with a broad […]

NASA’s Image of the Day Shows Saturnian Moons Prometheus and Pan

Image of Saturnian Moons Prometheus and Pan

This NASA image of the day shows Saturn’s moons Prometheus and Pan through Saturn’s rings captured in visible violet light by the Cassini spacecraft narrow-angle camera. The ring-region Saturnian moons Prometheus and Pan are both caught “herding” their respective rings in this image. Through their gravitational disturbances of nearby ring particles, one moon maintains a […]

Hi-C Captures the Highest-Resolution Images Ever of the Sun’s Corona

The Highest Resolution Images Ever Taken of the Suns Atmosphere

Using a resolution five times higher than previous imagers, NASA’s High Resolution Coronal Imager (Hi-C) captured the highest-resolution images ever taken of the sun’s million-degree solar corona. The optics engineering expertise at the NASA’s Marshall Space Flight Center in Huntsville, Alabama, made it possible for a group of solar scientist to see into the sun’s […]

Astronomers Measure the Temperature of the Universe 7.2 Billion Years Ago

Radio Waves from a Bright Quasar Pass Through a Galaxy

Using the CSIRO Australia Telescope Compact Array, scientists led by Sebastien Muller have made the most precise measurement ever of how the universe has cooled down during its 13.77 billion year history. The researchers studied molecules in clouds of gas in a distant galaxy, so far away that its light has taken half the age […]

Scientists Create “Ghost-Illusion” Cloaking Device

The Schematic Composition and Equivalence of the Ghost Illusion Device

Using the space transformation theory and engineering capability of metamaterials, researchers from Southeast University in China, National University of Singapore and University of Birmingham have developed a functional “ghost” illusion device capable of creating wave-dynamic virtual ghost images of the original object’s position under the illumination of electromagnetic waves. This device is different than the […]

The Hormone Oxytocin Plays a Key Role in Maintaining Social Relations in Chimpanzees

The Hormone Oxytocin in Chimpanzees is Likely to Play a Key Role in Maintaining Social Relations

Scientists from the Max Planck Institute have discovered that cooperative relationships between chimpanzees are facilitated by an endocrinological mechanism involving the hormone oxytocin, even when these are between non-kin. Animals which maintain cooperative relationships show gains in longevity and offspring survival. However, little is known about the cognitive or hormonal mechanisms involved in cooperation. Researchers […]

Silicon Nanoparticles React with Water to Produce Hydrogen

Spherical Silicon Nanoparticles React with Water to Quickly Produce Hydrogen

Scientists at the University at Buffalo have created spherical silicon nanoparticles that react with water to form silicic acid and hydrogen, a potential source of energy for fuel cells. Buffalo, New York — Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to University at Buffalo researchers. In a series of […]
