Nano-antidote provides long-term protection against nerve agents

Nerve agents are toxic chemicals that disrupt signals in the nervous system. They can be absorbed easily through skin contact or by breathing. Exposure to nerve agents interferes with nerve cell signaling and prevents muscles from relaxing, quickly leading to muscle paralysis and eventually death by asphyxiation or cardiac arrest. Treatment is possible but must be administered within minutes of exposure. No long-term vaccine or … Continue reading Nano-antidote provides long-term protection against nerve agents

Recycling Carbon Dioxide with Copper Catalysts

The Earth is undergoing climate change due to human activity. One facet of this change is the Greenhouse Effect, where molecules in the atmosphere trap heat, resulting in globally increasing temperatures. Carbon dioxide is a molecule produced in dangerous amounts by activities like farming and burning fossil fuels. Thus far, sustainably converting carbon dioxide to useful chemicals has been difficult, but scientists at the Lawrence … Continue reading Recycling Carbon Dioxide with Copper Catalysts

3D Printed Robot Plays Jingle Bells and More on the Piano

When looking for the perfect soundtrack to accompany your holiday celebrations, consider putting away the traditional albums and opting for this technologically savvy rendition of Jingle Bells instead.  The performer, the latest work from Josie Hughes and colleagues at the University of Cambridge, is none other than a robot hand designed to play the piano without moving its fingers.  While it may not be a … Continue reading 3D Printed Robot Plays Jingle Bells and More on the Piano

Treating knee osteoarthritis with a nanoparticle injection

Osteoarthritis is a joint disease that occurs when the cartilage (the flexible and slippery tissue that protects the ends of bones in the joints) wears away, causing bones to rub against each other. Common causes of osteoarthritis include aging, sports injuries, and excess body weight. Scientists from Tsinghua University and Shanghai Jiao Tong University have developed nanoparticles that can be injected as lubricant into the … Continue reading Treating knee osteoarthritis with a nanoparticle injection

China’s Genetically Edited babies: What really happened?

A Chinese researcher, He Jiankui, shocked the world two weeks ago when he revealed that the world’s first genetically edited babies had been born. Jiankui claimed to have edited embryos before implanting them into the mother as part of an otherwise routine in vitro fertilization (IVF) procedure. Since his bold announcement via YouTube, the scientific community at-large – both in the United States and in … Continue reading China’s Genetically Edited babies: What really happened?

Seeing with Gravity: How invisible particles can be observed in outer space

Everyone on Earth is familiar with gravity to some extent; it is the force that pulls us down to the planet’s surface. In fact, all objects with mass tug on other objects moving around them because of gravity. The strength of the gravitational pull depends on the mass of the object, and is often too weak to notice. However, for things as massive as galaxies, … Continue reading Seeing with Gravity: How invisible particles can be observed in outer space

The Secret to a Spider’s Superpowered Silk

If you have ever swatted a spider web away from a dusty corner of the house, congratulations—you have unknowingly dismantled one of the toughest materials known to man. The silk which spiders use to spin their webs and capture prey is five times stronger than steel, yet lightweight and more flexible than rubber. Because of these remarkable properties, scientists have been trying for years to … Continue reading The Secret to a Spider’s Superpowered Silk

Worth the Weight: The kilogram is finally being redefined

In a basement vault near Paris, under a series of nested bell jars, sits a one kilogram platinum-iridium cylinder. Even as it wears away or collects dust particles, it is still exactly one kilogram. That’s because it is the kilogram: “Le Grand K.” For more than 100 years, it has been the international standard for the unit of mass, even though its mass has changed … Continue reading Worth the Weight: The kilogram is finally being redefined

The Electron Electric Dipole Moment: How the Shape of the Electron’s Field could Hint at New Particles

The matter in our universe is made of atoms; atoms are made of protons, neutrons, and electrons; and protons and neutrons are made of quarks. In our current theory of particle physics, electrons and quarks are elementary particles–they are the foundation of everything else. The full catalog of all known elementary particles and their interactions is called the Standard Model (SM). The SM has been … Continue reading The Electron Electric Dipole Moment: How the Shape of the Electron’s Field could Hint at New Particles
