Room Temperature Simultaneous Femtosecond X-ray Spectroscopy and Diffraction of Photosystem II

Photosystem II

Researchers have taken a step forward towards producing artificial photosynthesis systems that would provide clean, green and renewable energy. Using pulses of X-rays from SLAC’s Linac Coherent Light Source, researchers were able to simultaneously image at room temperature the atomic and electronic structures of photosystem II, a metalloenzyme critical to photosynthesis. From providing living cells […]

Solving the Mystery of Saturn’s Moonlets

Unlocking the Mystery Behind Saturns Moonlets

Scientists at Loughborough University have revealed a new computer model that could help solve the mystery of Saturn’s moonlets. Research by Loughborough University physicists casts new light on Saturn’s moonlets – and could help solve some of the mysteries surrounding planet formation. Saturn’s F ring has long been of interest to scientists as its features […]

Understanding How Cells Package Fat

Fat is Stored in the Body in Two Distinct Ways

A newly published study suggests that fat is stored in the body in two distinct ways and may lead to ways to prevent cells from storing excess fat and possibly to new approaches for treating obesity. Fat is stored in the body in two distinct ways, Yale researchers have discovered. While the finding may not […]

CMS Test to Detect the Genetic Signals of Positive Selection

Looking for the Footprints of Positive Selection

Researchers from the Broad Institute have developed a tool known as the Composite of Multiple Signals (CMS) test to detect the genetic signals of positive selection and trace these signals to specific sites in the genome, generating a list of 412 candidate signals. For decades, the human genome could only tell us what we already […]

Spitzer Views Star-Forming Region W5

Star Forming Region W5

This NASA image of the day shows the star-forming region called W5. Generations of stars can be seen in this infrared portrait from NASA’s Spitzer Space Telescope. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are […]

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 […]

Engineers Show Feasibility of Organic Topological Insulators

Organic Topological Insulators

Engineers at the University of Utah are the first to demonstrate organic topological insulators, organic materials that conduct electricity on their molecular edges, but act as an insulator inside. University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their edges, but act as an insulator inside. […]
