Scientists have long known that learning requires the flow of calcium into and out of brain cells. But researchers at Columbia's Zuckerman Institute have now discovered that floods of calcium origina… [+6820 chars]
Following Tuesday's successful spacewalk, the Expedition 66 crew members aboard the International Space Station (ISS) is set to welcome three new crewmates. The Soyuz MS-21 spacecraft carrying three … [+1235 chars]
It's the largest hornet in the world and one of the most invasive species threatening American crops today. Now, scientists in California claim they know how the Asian giant hornet, also known as the… [+2125 chars]
MIT engineers and collaborators have developed a new acoustic fabric that can remedy hearing trouble. The fabric converts sound first into mechanical vibrations, then electrical signals, like our ear… [+3341 chars]
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-… [+7285 chars]
A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of abrupt global warming known as the Paleocene–Eocene Thermal Maximum (PETM) 56 million years ago. A new… [+4411 chars]
In a pair of world firsts, UBC scientists have 3D printed human testicular cells and identified promising early signs of sperm-producing capabilities. The researchers, led by UBC urology assistant … [+3920 chars]
Parkinson's disease is a neurodegenerative disorder characterized by the destruction of a specific population of neurons: the dopaminergic neurons. The degeneration of these neurons prevents the tran… [+3215 chars]
The golden spiral arms of a distant galaxy sparkle in new images from the European Southern Observatory (ESO). The galaxy , known as NGC 4254 or Messier 99, is an example of a grand design spiral g… [+1787 chars]
Think evolution is a slow, gradual process? Tell that to fruit flies. In a new report in Science, researchers from the University of Pennsylvania used a controlled field experiment to show that flies… [+6498 chars]
Methanotrophic bacteria consume 30 million metric tons of methane per year and have captivated researchers for their natural ability to convert the potent greenhouse gas into usable fuel. Yet we know… [+4708 chars]
Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for in… [+4276 chars]
