Digging through history: Theorists use old LHC data to search for new particles

The Large Hadron Collider (LHC) near Geneva, Switzerland, is the largest and most energetic particle collider in the world. Since it was activated in 2008, it has collided nearly a quadrillion protons. When particles collide they shatter, annihilate, and completely reorganize into a firework of new particles flying out in all directions, producing hundreds of millions of gigabytes of data. Physicists have used this data … Continue reading Digging through history: Theorists use old LHC data to search for new particles

Scientists control rat’s movements with their minds

The concept of mind control sounds like something that only exists in sci-fi movies. Until now. Recent work from Zhejiang University on developing a system appears to allow human mind control over the rat’s movements. This “brain-to-brain interface”, or BBI, is achieved by wirelessly coupling the brains of a human operator and a “rat cyborg” and transmitting brain activity in real time. Brain cells communicate … Continue reading Scientists control rat’s movements with their minds

Efficient drug delivery platform into the brain

Treatment of neurological disorders, such as Parkinson’s disease and stroke, has always been a challenging task, partly due to the existence of the blood-brain barrier (BBB). The BBB is a border that separates the blood circulation from the surrounding brain tissue. In a healthy brain, the BBB only allows the passage of nutrients crucial to brain function, while restricting the transportation of other substances, including … Continue reading Efficient drug delivery platform into the brain

‘Pacemaker for the brain’ may help prevent seizures and treat movement disorders

Anyone who has ever been scolded for talking over someone knows that speaking and listening simultaneously is a hard thing to do. Conducting an intelligent conversation requires active listening, understanding the received knowledge, and crafting a meaningful response, which often requires blending the new information with one’s own experiences. On a microscopic scale, each neuron in the brain must do exactly this – listen to … Continue reading ‘Pacemaker for the brain’ may help prevent seizures and treat movement disorders

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?
