BPA Causes Interspecies Mating
The hormone-disrupting chemical makes it hard for some fish to recognize their own species, a problem that could ripple throughout ecosystems.

Scientists Create ‘MRI’ of Sun’s Interior
The equivalent of an MRI of the sun was created by scientists, who studied high-resolution images of the sun’s surface taken by NASA’s Solar Dynamics Observatory showing motions on the sun’s surface caused by convection. The findings challenge our existing explanations of the formation of sunspots and magnetic field generation.

Hubble Captures ‘Ghost Galaxies’ of Early Universe
The Hubble Space Telescope has captured images of three odd galaxies that may help scientists solve a 13 billion-year cosmic mystery. The galaxies are so old and faint that astronomers nicknamed them “ghost galaxies” in a description. The objects are among the smallest and faintest galaxies near our own Milky Way galaxy, researchers said. “These…

Graphene Holes ‘Heal Themselves’
Graphene – the “wonder material” made of sheets of carbon just one atom thick – undergoes a self-repairing process to correct holes, researchers report. Graphene’s outstanding mechanical strength and electronic properties make it a promising material for a wide range of future applications. But its almost ethereal thinness makes it easily damaged when working with…

A Blip That Speaks of Our Place in the Universe
It is natural for those not deeply involved in the half-century quest for the Higgs Boson – one of the most important missing pieces of the jigsaw puzzle that is nature – to ask why they should care about this seemingly esoteric discovery. There are three reasons. First, it caps one of the most remarkable…

Why “Big Science” Is Worth the Cost
Physicists at CERN delivered big news when they announced the almost certain discovery of the Higgs boson — the so-called “God particle” thought to be the key to the formation of matter, and life. They were able to detect what they believe to be the Higgs boson by firing particles around a giant, $10 billion…

Can Higgs Research Be Used to Transport Matter or Bend Time?
A century after Albert Einstein came up with his theories of relativity, a constellation of Global Positioning System satellites is orbiting Earth, making practical use of his ground-breaking understanding of time. If the discovery of the Higgs boson particle pans out, will even more mind-bending technologies result? It’s theoretically possible, says Arizona State University physicist…

Giant Filament of Dark Matter Connects Galaxy Clusters
A giant string of invisible dark matter has been discovered across the universe between a pair of galaxy clusters. The filament forms a bridge between two huge clusters called Abell 222 and Abell 223, which lie 2.7 billion light-years away. The universe is thought to be filled with such strings of dark matter, a mysterious…

Health Apps Bump Up Against FDA
Health apps are hot, but until now the field has been unregulated. It is hard to know which apps actually live up to their claims or provide accurate information. Now, the FDA is laying down the law, releasing a first draft of guidelines that require developers making medical claims to apply for FDA approval. But app developers are bristling.

A Closer Look at the Higgs Boson
Scientists working at the world’s biggest atom smasher near Geneva have announced the discovery of a new subatomic particle that looks remarkably like the long-sought Higgs boson. Sometimes called the “God particle” because its existence is fundamental to the creation of the universe, the hunt for the Higgs involved thousands of scientists from all over…
