Supernova Remnants Accelerate Cosmic Rays

W44 Supernova Remnant

A newly published study provides the first clear-cut evidence that supernova remnants accelerate cosmic rays to incredible speeds. A new study using observations from NASA’s Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step […]

Passenger Mutations Can Slow or Even Halt Tumor Growth

Cancer Mutations Slow Tumor Growth

A newly published study shows that so-called passenger mutations can slow or even halt tumor growth and suggests that cancer should be viewed as an evolutionary process whose course is determined by a delicate balance between driver-propelled growth and the gradual buildup of passenger mutations. A typical cancer cell has thousands of mutations scattered throughout […]

The Large Hadron Collider Prepares for Shutdown

LHC Maintenance

On February 14, 2013, the Large Hadron Collider will begin “Long Shutdown 1,” a shutdown period of almost two years during which the LCH will undergo large-scale work to modernize the infrastructure and prepare the LHC for operation at higher energy. The Large Hadron Collider (LHC) has provided physicists with a huge quantity of data […]

New Model Facilitates Predictions About How Nanoparticles Form

How Nanoparticles Form

While studying magnetite nanoparticles, researchers from the Max Planck Institute developed a new model for predicting how nanoparticles form. Nanoparticles are versatile harbingers of hope: They can serve as active medical agents or contrast media just as well as electronic storage media or reinforcement for structural materials. Researchers from the Max Planck Institute of Colloids […]

Combustible Gases Enable Soft Robots to Jump

Leaping Robots

Using small explosions produced by a mix of methane and oxygen, scientists at Harvard University have developed a soft robot that can leap as much as a foot in the air. The technology may prove useful for future robots designed to avoid obstacles during search and rescue operations following a disaster. They can already stand, […]

Data Suggests Rare Explosion Created Milky Way’s Youngest Black Hole

Supernova Remnant W49B

By tracing the distribution and amounts of different elements in the stellar debris field, scientists were able to compare Chandra data to theoretical models of how a star explodes, finding that in the W49B supernova, jets shooting away from the star’s poles mainly shaped the supernova explosion and its aftermath. New data from NASA’s Chandra […]

Neuroscientists Isolate Chills at a Cellular Level, Turn Off the Ability to Feel Cold

Scientists Turn Off the Ability to Feel Cold

Neuroscientists at USC have isolated and ablated the neurons that express TRPM8, finding that mice depleted of TRPM8 neurons could not feel cold but still responded to heat. USC researchers have isolated chills at a cellular level, identifying the sensory network of neurons in the skin that relays the sensation of cold. David McKemy, associate […]
